Given that RQ=TQ, Angle QSR=(9a+48) and Angle QST=(6a+50), find Angle QST

Answer: 50x+200=y

Step-by-step explanation:

This is the answer because the number of hours is not provided leaving us to multiply 50 by x, 200 is the flat fee so we will know to automatically add that to our first step and since y is the total this will form the equation, 50x+200=y.

Answer:

Line CE

Step-by-step explanation:

We know that lines are perpendicular when their intersections form 90° angles (see below diagram). ∠E is a 90° angle, so line CE is perpendicular to line DF. Assuming that line DF is parallel to line AB, we now know that line CE is also perpendicular to line AB.

Answer: y=-5/3x+4

Step-by-step explanation:

Since the line is parrallel that means that the gradient is the same

We can reorder 5x+3y=6 into 3y=-5x+6 but in order to find the gradient the number infront of y must be 1 so...

3y=-5x+6

y=-5/3x+2

Now we know that the gradient is -5/3

To find th y-intercept we just subsitute the points it passes through (3, -1) into the equation

y=-5/3x+c

-1=-5/3(3)+c

-1=-5+c

Answer:

63 inches

Step-by-step explanation:

The perimeter of a rectangle is found by adding all of the side lengths. Since both pairs of opposite sides have the same length, an equation for the perimeter can be written like this:

[tex]P=2w+2l[/tex]

Where w and l represent the width and length.

Since we are asked to find the length, rewrite the equation in terms of l:

[tex]l=\frac{P-2w}{2}[/tex]

We know the values for P and w, so plug those in:

[tex]l=\frac{150-2(12)}{2}[/tex]

Now simplify!

[tex]l=\frac{126}{2}=63[/tex]

Answer:

l = 63 in  

Step-by-step explanation: If the P=150 in  W=12 in so .... using the formula P=2 (l + w) you get  L= P/2 - W = 150/2 - 12 = 63 in. I hope this helps!

Answer:

11

Step-by-step explanation:

Plug in 1 to the function:

f(x) = 6x + 5

f(1) = 6(1) + 5

f(1) = 6 + 5

f(1) = 11

The vector that translates P to P' is (-4 , 6)

A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction either in it’s range(involving values of y) or in it’s domain(involving values of x).

The points are given;

[tex]{P = (3, -2)}\\{P' = (-1, 4)}[/tex]

The translation rule is calculated as:

{(x,y) = P' - P}

So, we have:

{(x,y) =(− 1, 4) - (3, − 2)}

Combine the terms;

{(x,y) = (-1 -3 , 4 + 2)}

{(x,y) = (-4 , 6)}

Express as vectors;

(x, y) = (-4 , 6)

Hence, the vector that translates P to P' is  (-4 , 6)

Using simplification, if the total ticket sales was $1316, then 70 children, 78 students and 35 students attended.

From the given question,

We know that the capacity of movie theater is 183.

The theater charges $5.00 for children, $7.00 for students and $12.00 of adults.

There are half as many adults as there are children.

If the total ticket sales was $1316, then we have to find how many children, students, and adults attended.

Let the number of children that attended = x

Since, there are half as many adults as children.

Therefore number of adults = 1/2x =0.5x

We know there are total of 183 tickets

Therefore number of students = 183 - x - 0.5x

number of students = 183 - 1.5x

Each children ticket costs = $5

Then the price of children tickets = 5x

Similarly for adults each ticket costs = $12

So total cost of adult ticket = 12×0.5x = $6x

Now the cost of student tickets = 7(183 - 1.5x)

As given that

Total cost of all tickets = $1316

So the expression should be

5x + 6x + 7(183 -1.5x) = 1316

Simplifying

11x + 1281 - 10.5x = 1316

Subtract 1281 on both side

11x + 1281 - 10.5x-1281 = 1316-1281

Simplifying

0.5x = 35

Divide by 0.5 on both side we get

x = 70 children

Now finding the number of adults

= 0.5x

= 0.5×70

= 35 adults

Now finding the number of students

= 183 - 1.5x

= 183 - 1.5×70

= 183 - 105

= 78 students

Hence, If the total ticket sales was $1316, then 70 children, 78 students and 35 students attended.

Answer: Steph is 16 today

Step-by-step explanation:

Austin age today = x

Austin in 4 years = x+4

Steph age today = 4x (because Austin is 1/4 her age today)

Steph age in 4 years is 4x + 4

In 4 years Austin's age is 2/5 of Steph's, so:

2/5 (x+4) = 4x + 4

Now solve for x!

x+4 = (8/5)x + 8/5

12/5 = (3/5)x

Therefore Austin is 4 years old today (x=4) and...

Steph age today = 4x = 4x4 = 16

The Law of detachment states that if m then n and m is true then q is true.

If two angles are complementary, then the two angles' sum is 90 degrees.

This is m∠E + m∠F = 90.

Option C is the correct answer

The Law of detachment states that if m then n and m is true then q is true.

We have,

If two angles are complementary, then the sum of their measures is 90°.

This is in the form of,

If M then N and if M is true then N must be true.

So,

If two angles are complementary, then the two angles' sum is 90 degrees.

If the two angles are m∠E and m∠F.

m∠E + m∠F = 90

Thus,

If two angles are complementary, then the two angles' sum is 90 degrees.

this slope of a line question is such a common question.  I feel like math teachers all over don't understand how to teach this subject.  Just so you know,  I answer a question like this about 10 times a day when I am on here.  It's like one of the most common questions.  

Here is my copy and paste answer for this...

point P1 (-3,7.2)  in the form (x1,y1)

point P2(2,-2.3)  in the form (x2,y2)

slope = m

m = (y2-y1) / (x2-x1)

m = (-2.3-7.2) / (2-(-3))

notice all the minus signs and how i'm being very careful to keep close track of them.  Also, who ever has written this question is intentionally trying to trip you up by putting in all the minus signs,  there is no need for so many minus signs to teach this well.  Anyway...

m = -8.5 / 5

m = - 1.7

the problem question ends there , but there is a common place this question is supposed to take you.   to the point slope formula.  but for another question.

The slope of (-3, 7.2) and (2, -2.3) is -1.9.

Consider,

(x1, y1) = (-3, 7.2)

(x2, y2) = (2, -2.3)

slope = (y2 - y1)/(x2-x1)

slope = ((-2.3) - (7.2))/((2) - (-3))

slope = (-9.5)/(5)

slope = -1.9

Therefore, the slope of the given points (-3, 7.2) and (2, -2.3) is -1.9.

Answer:

1. 30 years old

2. 7 years old

3. 5 hours

Step-by-step explanation:

We can solve all of these problems using algebraic equations.

1. In this question, we will use variable x to represent the age of Mrs. Olsen's daughter.

In 10 years, x - 20 = 2x. That means that in 10 years, Mrs. Olsen will be 40 years old. That means she is 30 right now.

2. In this question, we will use variable x to represent the age of Alyssa.

If, in 30 years, their total age is 88, their current total is 28. Tyler is 3 times as old as Alyssa, so Tyler is 21 and Alyssa is 7.

3. Ryan leaves home at 50 mph. That means, in an hour Ryan will be 50 miles away from home. At that point, Jacob leaves home at a speed of 60 mph, so the gap between them closes by 10 miles each hour. That means that Jacob will take 5 hours to catch up, counting from when he left (how far is this workplace jeez?!?!?!?).

We could also represent this with a graph.

Hour 1: R = 50, J = 0 (Jacob leaves after this hour so it doesn't count for the answer)

Hour 2: R = 100, J = 60

Hour 3: R = 150, J = 120

Hour 4: R = 200, J = 180

Hour 5: R = 250, J = 240

Hour 6: R = 300, J = 300

The solutions to the expression x³ + 87 = 7x² + x are given as follows:

–3, 5 + 2i, 5 – 2i.

The equation is defined as follows:

x³ + 87 = 7x² + x.

In standard format, it is given by:

x³ - 7x² - x + 87 = 0.

It has one negative solution, hence from the options it is:

x = -3.

The verification is:

(-3)³ - 7(3)² - (-3) + 87 = 0.

Considering the linear factor (x + 3), the function can be written as follows:

x³ - 7x² - x + 87 = (x + 3)(ax² + bx + c).

As the product of a linear function and a quadratic function results in a cubic function.

Expanding the right side of the equality, we have that:

ax³ + (b + 3a)x² + (3b + c)x + 3c = x³ - 7x² - x + 87.

Hence the coefficients of the quadratic equation are given as follows:

Hence the equation is:

x² - 10x + 29 = 0.

And the solutions, using a quadratic equation calculator, are given as follows:

The value of the number is 35

Algebraic expressions are the idea of expressing numbers using letters or alphabets without specifying their actual values.These letters are called variables. An algebraic expression can be a combination of both variables and constants. Any value that is placed before and multiplied by a variable is a coefficient.

If the number is represented by x then,

1x/5+3x= 2x+42

making the left hand side a single fraction, then,

(x+15x)/5= 2x+42

16x/5= 2x+42

multiply both sides by 5
