Answer:
81, 64, 47, 30, 13, -4
Answer:
The next two numbers are 13 and -4.
Step-by-step explanation:
We are subtracting 17 each time.
30 - 17 = 13
13 - 17 = -4
f (x)=2^2-7x-6 Find f (6)
solve (2x-10)=(65-x) show your work plz!
Answer: x=25
Step-by-step explanation:
Simplifying
(2x + -10) = (65 + -1x)
Reorder the terms:
(-10 + 2x) = (65 + -1x)
Remove parenthesis around (-10 + 2x)
-10 + 2x = (65 + -1x)
Remove parenthesis around (65 + -1x)
-10 + 2x = 65 + -1x
Solving
-10 + 2x = 65 + -1x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add 'x' to each side of the equation.
-10 + 2x + x = 65 + -1x + x
Combine like terms: 2x + x = 3x
-10 + 3x = 65 + -1x + x
Combine like terms: -1x + x = 0
-10 + 3x = 65 + 0
-10 + 3x = 65
Add '10' to each side of the equation.
-10 + 10 + 3x = 65 + 10
Combine like terms: -10 + 10 = 0
0 + 3x = 65 + 10
3x = 65 + 10
Combine like terms: 65 + 10 = 75
3x = 75
Divide each side by '3'.
x = 25
Simplifying
x = 25

Select the equation that contains the point (3,6) and in which the slope equals 1
Answer:
I think it would be y + 6 = x + 3
Step-by-step explanation:
Because they both have to be positive because the points are positive. Also the slope has to be 1 so x cannot have a number with it or else it changes the value.
I would say it is 1)y + 6 = x + 3 but I am not no genius

3. The sum of the two numbers is5/9
If one of the numbers is
1/3 find the other
Step-by-step explanation:
let the one number be X.
and
second one 1/3
then
1/3 +X = 5/9
X = 5/9-1/3
X =( 5-3) /9
X = 2/9 Ans
Answer:
The other number will be 2/9.
Step-by-step explanation:
Let the second fraction be x :
[tex] \frac{1}{3} + x = \frac{5}{9} [/tex]
[tex]x = \frac{5}{9} - \frac{1}{3} [/tex]
[tex]x = \frac{5}{9} - \frac{3}{9} [/tex]
[tex]x = \frac{2}{9} [/tex]

4. Find the slope of the line through the
points A(8, 7) and B(5,-2).
Explanation
Answer:
Your slope would be 3.
Step-by-step explanation:
To find the slope from two points, you would need to use the formula: y2-y1/x2-x1
In this case, the equation would look like -2-7/5-8.
-2 - 7 = -9
5 - 8 = -3
-9/-3 = 3
Slope: 3

Write an equation in standard form of the line that passes through the following
points, where a ≠0 and b ≠0.
Answer:
The equation =3 is equivalent to = 0 +3. From this form, we know the line has slope =0.
Step-by-step explanation:
Answer:
ax + by = c
Step-by-step explanation:
The standard form of the line is
ax + by = c; where a, b and c are numbers
Also a and b are coefficients are not zero so there are x and y terms.
help plz , i don't know how to find it
Answer:
y = 2x + 4
Step-by-step explanation:
y = mx+b
m represents the slope, and b is the y-intercept
The slope is 2 as it's going up 2 unit squares each time, and the b is 4 because that's where the y-axis gets intercepted.
so the answer is y = 2x + 4

Pleas help meh!!I really need help!!!
Answer:
360ft^2
Step-by-step explanation:
We know that the height is always 8 ft. So lets find the area of two of the 4 walls.
We multiply by 2 because there are two of the same wall.
2(8ft x 10ft) = 160ft^2
Now lets find the area of the other wall.
2(8ft x 15ft) = 240ft^2
Now we add it up
160 + 240 = 400
400ft^2
But wait! We aren't done yet! We still have to subtract out the door and window which is 60ft^2.
400 - 60 = 360
360ft^2

help me find the perimeter plzzz!
Answer:
2m-4
Step-by-step explanation:
double both of them and just simplify
the first one will become (6m-12) and the second will become (-4m+8)
subtract 6m and -4m so it's 2m
subtract -12 and 8 so it's -4
so the answer is 2m-4
Answer:
B. 2m - 4
Step-by-step explanation:
When simplifying the expression (3m - 6) + (3m - 6) + (-2m + 4 ) + (-2m + 4) while trying to find the perimeter, you will find your answer to be 2m - 4.

The length of segment AE is 5 centimeters.
a. what is the length of segment CD?
b. what is the length of segment AB?
c. Name a segment that had the same length as segment AB. segment________
Answer/Step-by-step explanation:
Segment AE is a radius of the circle with center of A.
Any segment that has its origin from the center of the Circle, A, and meets at any point along the circumference of the circle, is equally a radius, and would have the same length as segment AE.
Thus:
a. Length of segment CD:
Segment CD is half of the circle. So it is the diameter of the circle.
Diameter of a circle = 2 × length of the radius.
Therefore,
CD = 2 × AE
CD = 2 × 5 (substitution)
CD = 10 cm
b. AB is a radius.
Therefore, AB = AE
AB = 5 cm
c. Any of these segments are also radius of the circle and also have the same length as segment AB:
Segment AG,
Segment AD
Segment FA
Segment AC

A public parking garage charges $5, plus an additional $2 per hour.
Choose the graph of the line.
Answer:
2nd one
Step-by-step explanation:
Graph-2 is correct line that represents the parking charge of the public garage.
What is a linear equation?A linear equation is an equation where the variable has the highest degree of 1.
Given, a public parking garage charges $5, plus an additional $2 per hour.
For 1 hour, the total cost will be = $(5 + 2 × 1) = $7.
For 2 hours, the total cost will be = $(5 + 2 × 2) = $9.
For 3 hours, the total cost will be = $(5 + 2 × 3) = $11.
For 4 hours, the total cost will be = $(5 + 2 × 4) = $13.
For 5 hours, the total cost will be = $(5 + 2 × 5) = $15.
Here, the increase in parking cost is in the form of linear equation and it increases $2 with the increase in every hour.
Therefore, graph-2 represents the actual line of cost of the parking charge and time.
