Step-by-step explanation:
Consider the line y = 3x - 1.
Find the equation of the line that is perpendicular to this line and passes through the point (-8, 3)
Find the equation of the line that is parallel to this line and passes through the point (-8, 3).
Answer:
y = -1/3x + 1/3
Step-by-step explanation:
The slopes of perpendicular lines are negative reciprocals.
The given line is
y = 3x - 1
This equation is written in the slope-intercept form, y = mx + b, where m is the slope.
slope of given line = m = 3
slope of perpendicular line = -1/3
Now we need the equation of the line with slope -1/3 that passes through the point (-8, 3)
y = mx + b
y = -1/3x + b
3 = (-1/3)(-8) + b
3 = 8/3 + b
9/3 = 8/3 + b
b = 1/3
y = -1/3x + b
y = -1/3x + 1/3
Solve for x if 2(5x + 2)2 = 48.

Answer:
1. It can clearly observed that all the ratios that are written in fractional form simplify to same fraction which means that all the ratios are equivalent.
2. None of them will taste different as the ratios are same.
Step-by-step explanation:
First of all we have to write the three ratios as fractions to see if the ratios are equivalent ratios or not.
We will see the water to cups ratio
The ratios in fractional form are:
[tex]=\frac{1}{3}\\=\frac{4}{12}\\=\frac{6}{18}[/tex]
Putting all the ratios together
[tex]\frac{1}{3} = \frac{4}{12} = \frac{6}{18}\\\frac{1}{3} = \frac{1}{3} = \frac{1}{3}[/tex]
1. It can clearly observed that all the ratios that are written in fractional form simplify to same fraction which means that all the ratios are equivalent. All the recipes will taste same.
2. None of them will taste different as the ratios are same.

Two shapes are similar if their corresponding angles are congruent and their corresponding sides are proportional. Triangle ABC is similar to triangle DEF. What conjecture can you make about the two triangles?
A.) Triangle ABC is bigger than triangle DEF.
B.) ∠A≅∠D.
C.) Triangle ABC is smaller than triangle DEF.
Answer:
B.
Step-by-step explanation:
they would be equal to one another
The solution is Option B) ∠A ≅ ∠D
What are Congruent Triangles?
Transformations change the size or position of shapes. Congruent shapes are identical, but may be reflected, rotated or translated. Scale factors can increase or decrease the size of a shape. Congruent Triangles simply mean the triangles that possess the same size and shape
Given data ,
Two shapes are similar if their corresponding angles are congruent Corresponding sides are proportionalTriangle ABC is similar to triangle DEFNow , Two shapes that are the same size and the same shape are congruent
And ,
For two triangles to be congruent, one of 4 criteria need to be met

2x=8
x=4
Answer:
x = 4
Step-by-step explanation:
The goal is to get x by itself.
1. Multiply both sides by 3 and you are left with:
7 + 2x = 15
2. Subtract 7 from both sides and you are left with:
2x = 8

You are riding a train. Your carry-on bag can weigh no more than 50 pounds. Your bag weighs 38 pounds.
Which inequalities represent how much weight you can add to your bag?
W > 50 - 38
50 > W - 38
38 + w < 50
W < 50 - 38
Can you add both a 9-pound laptop and a 5-pound pair of boots to your bag without going over the weight limit?
Yes, the total being added is 4 pounds, which is a solution of the inequality
No, the total being added is 14 pounds, which is not a solution to the inequality
Yes, the added weight needs to be less than 38 pounds, and 9 plus 5 is less than 38.
No, the added weight needs to be at least 38 pounds, and 9 plus 5 is less than 38.
Answer:
Let the additional weight that can be added be = x
Current weight of the bag = 38 pounds
Total weight can be = 50 pounds
The equation becomes:
38+x < or equal 50
x < or equal 50-38=12
Hence, a weight of 12 pounds cab be added to the current wight.
e. A person walked x feet and then half
that length again.
Answer:
3x/2 feet
Step-by-step explanation:
It is given that, a person walked x feet and then half of that length again. We need to find total distance covered by him.
Total distance covered = sum of path travelled
Initial distance = x feet
Extra distance covered = (x/2) feet
Total distance = x+x/2 = 3x/2 feet
So, he will cover 3x/2 feet.

What is Marathon?Around 490 BC, when the Persians invaded Greece, the marathon was first performed. The most well-known narrative concerns Pheidippides, a Greek messenger tasked with telling the Athenians of the Greeks' victory over the Persians at the Battle of Marathon.
Pheidippides went off on foot and ran nonstop because he thought the assignment was vital. He stormed into the government meeting at the city's gates, declared the Greek victory, then collapsed on the ground and passed away from weariness.
The longest southern path between the two cities, Greece and Athens, is around 40.8 kilometers long.

Step-by-step explanation:
The profit (in millions of dollars) for a producer of electric scooters can be modeled by P=-x^3+7x where x is the number of scooters produced (in millions). Currently the company produces 2 millions scooters and makes a profit of $6,000,000. What lesser number of scooters could the company produce and still yield the same profit?
Answer:
1 million scooters
Step-by-step explanation:
We are told that the profit (in millions of dollars) for a producer of electric scooters can be modeled by P = -x³ + 7x where x is the number of scooters produced (in millions).
We are told that currently the company produces 2 millions scooters and makes a profit of $6,000,000.
Thus, the profit equation is;
6 = -x³ + 7x
x³ - 7x + 6 = 0
We are given 2 as a root.
Let's try 1.
1³ - 7(1) + 6 = 0
0 = 0
So 1 is a root.
Thus, the lesser number of scooters the company could produce and still yield the same profit is 1 million scooters

According to the synthetic division below, which of the following statements
are true?
Check all that apply.
The question is not complete, so i have attached it.
Answer:
Options A, B & E are correct
Step-by-step explanation:
In the synthetic division attached, we see that:
: 2 , -2 & -12 are the coefficient of the dividend of the function 2x² - 2x - 12
: The divisor is 3
Thus;
x = 3 is a root of f(x) = 2x² - 2x - 12
Thus, (x - 3) is a factor of the dividend which is the function f(x) = 2x² - 2x - 12
- Now, from the attached image, the coefficients of the quotient are 2 , 4
- The quotient will be 1 degree less than the dividend since it was divided by the factor (x - 3)
The degree of the dividend will be 2 since it contains x²
Thus, the degree of the quotient will be 1
Therefore, the quotient in factor form is (2x + 4)
Looking at the given statements in the options;
- Option A is true, because we have established earlier that 3 is a root of f(x) = 2x² - 2x - 12
- Option B is true because we have established that (x - 3) is a factor of 2x² - 2x - 12
- Option C is not true because the factor is (x + 3) and not (x - 3)
-Option D is not true because the root is 3 and not -3
- Option E is true because we have established that quotient as a factor is: (2x + 4)
Thus, the correct options are A , B , E

weighs 7.8 pounds. What is the percent of increase in the baby's weight
from the time he was born to two weeks later? *
Answer:How much weight should newborns gain?
A healthy newborn is expected to lose 7% to 10% of the birth weight, but should regain that weight within the first 2 weeks or so after birth. During their first month, most newborns gain weight at a rate of about 1 ounce (30 grams) per day.

Write, in slope intercept form, the equation of the line that passes through (8, -9) and has a slope of -5/4.
Answer:
The equation in the slope-intercept form will be:
[tex]y=-\frac{5}{4}x+1[/tex]
Step-by-step explanation:
Given
slope = m = -5/4point = (8, -9)As we know that the equation of a line in point-slope form is
[tex]y-y_1=m\left(x-x_1\right)[/tex]
substituting the values m = -5/4 and point = (8, -9)
[tex]y-\left(-9\right)=\frac{-5}{4}\left(x-8\right)[/tex]
[tex]y+9=\frac{-5}{4}\left(x-8\right)[/tex]
Writing the equation in slope-intercept form
[tex]y=mx+b[/tex]
where m is the slope, and b is the y-intercept
so the equation of the line in slope-intercept form becomes
[tex]y+9=\frac{-5}{4}\left(x-8\right)[/tex]
subtract 9 from both sides
[tex]y+9-9=\frac{-5}{4}\left(x-8\right)-9[/tex]
[tex]y=-\frac{5}{4}x+1[/tex]
Therefore, the equation in the slope-intercept form will be:
[tex]y=-\frac{5}{4}x+1[/tex]
