6x + 9 = 4x - 3
2x + 9 =-3
Multiply both sides by 2
- 4(5x-7)=-18
5x - 7 = 4.5
Multiply both sides by-4
8 - 10x = 7+ 5x
4 - 10x = 3 + 5x
Multiply both sides by 1
x = 4
5x =- 16
Add to both sides
- 4x
12x + 4 = 20x + 24
Add to both sides
3x + 1 = 5x + 6
find the equation of the linear function represented by the table below in slope-intercept form. picture of table is below
Answer:
y = 3x+1
Step-by-step explanation:
Well, slope intercept form is y =mx+b, and to find the slope, you have to take two of the examples for y, and divide it by 2 examples of the x, like so:
7- (-5) / 2- (-2) which is 12/4 which is 3, so the slope is 3.
we now can make the first part of the equation:
y = 3x + b
Now we just need "b". To find b, just substitute the x and y values for two values shown on the chart, such as -2 and -5. (They have to be on the same row).
-5 = 3x-2 + b
you get:
-5 = -6+b
which is equal to:
b = 1
So, putting b back in the equation, you get:
y = 3x+1
start with the value of 25, double it, and then calculate the percent increase.
Answer: 100%
Step-by-step explanation:
If you start with 25 and double it you will get 50 and 25 is half of 50 so the percent increase will be 100%.
What is the value of x that makes the equation true 2x+20=-2(4x-25)
2x + 20 = -2(4x - 25)
2x + 20 = -8x + 50
+8x +8x

10x + 20 = 50
-20 -20
_______________
10x = 30

Which graph represents the equation 3x+y=-1?
Answer:
The answer is c
Step-by-step explanation:
I put this into my graphing calculator to solve it. To do this by hand though you need to choose two numbers and enter then for x and that should give you the numbers the you need to plot on your graph.
Hope that help :)
Write an equation of the line passing through the point A(3,−4) that is parallel to the line y = −x+8.
Answer:
y = -x -1
Step-by-step explanation:
The x- and y-coordinates will be the same for the parallel line, so we only need to find the constant that needs to replace the +8 in the given equation.
y = mx +b
y = -x +b . . . . . with the coefficient of x filled in
-4 = -(3) +b . . . with the given point filled in
b = -1 . . . . .add 3 to both sides
The equation is ...
y = -x -1
Answer:y = -x -1

Goran rented a truck for one day. There was a base fee of $20.95, and there was an additional charge of 71 cents for each mile driven. Goran had to pay
$228.98 when he returned the truck. For how many miles did he drive the truck?
Answer:
293 Miles
Step-by-step explanation:
$228.98-$20.95=$208.03
$208.03/$0.71=293 miles
Answer: 94 miles
Step-by-step explanation:
Do $228.98/.71 = 322.51
322.51-228.98= 93.53
what is the slope of the line
Answer:
The slope is 1/2.
Step-by-step explanation:
To find the slope of a line, use the equation (y2-y1 / x2-x1)
Let's say (4,3) is x2 and y2. That means (0,-2) is x1 and y1.
(3 - 0) / (4 - -2)
(3 - 0) / (4 + 2)
3/6, which simplifys to 1/2

Which of the following is the point and slope of the equation y - 2 = 3/2(x - 7)?
(7, 2), 3/2
(7, 2), 3
(-7, -2), 3/2
(7, -2), 3
Point-slope form of the linear functions is like this :
[tex]y - y(point) = (slope) \times ( \: x - x(point) \: ) \\ [/tex]
[tex]y - 2 = \frac{3}{2}(x - 7) \\ [/tex]
So :
[tex]slope = \frac{3}{2} \\ [/tex]
And
Point = ( 7 , 2 )

PLEASE HELP!!! CONVERT TO STANDARD FORM (y=ax^2+bx+c
f(x)=2(x-3)^2+7
Answer:
y = 2x^2 - 12x + 25Step-by-step explanation:
Given function
f(x)=2(x-3)^2+7Converting to standard form
y = 2(x - 3)^2 + 7y = 2(x^2 - 6x + 9) + 7y = 2x^2 - 12x + 18 + 7y = 2x^2 - 12x + 25Which is the equation for the line in slope-intercept form if:
m = -3/2 : b = 5
y = 5x + (-3/2)
y=(-3/2)x+ 5
Oy+(-3/2) = 5x

Round 0.5289 to the nearest thousandth.
Answer:
0.5289 to the nearest thousandth is 0.529.
Step-by-step explanation: If a number is less than 5, round down, but if a number is 5 or more, round up. The digit after the thousandths place is the digit we should look at to answer the question and it is 9, so we round up from 0.528 or 0.529. So, the answer is 0.529.
i’ve never really understood range
Answer:
( -∞, 3]
Step-by-step explanation:
Range is all possible y values that the graph covers.
So in this graph the legs extend all the way to y value -∞ (never mind the x value). However, the top is at y=3 and the graph is not extending above that. Hence the range is from -∞ to and including 3.
