102+39x=180
180-102=39x
78/39=x
-17=x-15 what does x equal?
Answer:
-17=x-15 +15
-2=x
Step-by-step explanation:
prove me wrong
-17 = x - 15
Move -15 over to -17, it becomes a positive.
15 - 17 = x
15 - 17 = -2
x = -2

The video streaming service that you want to use is represented with the equation below, where y represents the the total monthly cost of the service and x represents the number of videos you plan to stream each month:
y = $1.25x + $5.00
What is the total cost of the service for the month if you stream 30 videos?
Group of answer choices
$36.25
$151.25
$35.00
$42.50
Answer:
$42.50
Step-by-step explanation:
y = mx + b
x = how many videos you watched
y = 1.25(30) + 5.00 = 42.50

Consider the enlargement of the pentagon. A small pentagon has a bottom side length of x centimeters and left side length of 7 centimeters. A larger pentagon has a bottom side length of 7 centimeters and left side length of 15 centimeters. Not drawn to scale What is the value of x, rounded to the nearest tenth? 2.1 centimeters 3.3 centimeters 7.0 centimeters 15.0 centimeters
Answer:
[tex]x = 3.3cm[/tex]
Step-by-step explanation:
Given
Shape: Pentagon
Small
[tex]Bottom = x[/tex]
[tex]Left = 7cm[/tex]
Big
[tex]Bottom = 7cm[/tex]
[tex]Left = 15cm[/tex]
Required
Find x
From the question, we understand that the big pentagon is a dilation of the small pentagon.
What this means is that; both pentagons will have the same equivalent ratio.
The equivalent ratio, in this case is calculated using
[tex]Ratio = \frac{Bottom}{Left}[/tex]
For the small pentagon:
[tex]Ratio = \frac{x}{7cm}[/tex]
For the big pentagon:
[tex]Ratio = \frac{7cm}{15cm}[/tex]
Equate both ratios:
[tex]\frac{x}{7cm} = \frac{7cm}{15cm}[/tex]
[tex]\frac{x}{7cm} = \frac{7}{15}[/tex]
Cross multiply
[tex]15 * x = 7cm * 7[/tex]
[tex]15 * x = 49cm[/tex]
Make x the subject
[tex]x = \frac{49cm}{15}[/tex]
[tex]x = 3.267cm[/tex]
[tex]x = 3.3cm[/tex] --- approximated

Step-by-step explanation:
Form the diagram, you can see that UV is parallel to TS, this means that <UVS = < UTS
Given
<UVS = 5x + 38
<UTS = 12x - 28
Since the sum of opposite angle of a quadrilateral is 180 degrees, hence;
5x + 38 + 12x - 28 = 180
Collect like terms
5x + 12x - 28 + 38 = 180
17x + 10 = 180
17x = 180-1-
17x = 170
x = 170/17
x = 10
hence the value of x is 10

A subset of values of the function g(x) is shown in the following table.
Answer:
Option (4)
Step-by-step explanation:
x g(x) Ist difference IInd difference Ratio
1 13 - - -
2 3 3 - 13 = -10 - [tex]\frac{3}{13}[/tex]
3 -3 -3 - 3 = -6 -6 - (-10) = 4 [tex]\frac{-3}{3}=-1[/tex]
4 -5 -5 - (-3) = -2 -2 - (-6) = 4 [tex]\frac{-5}{-3}=\frac{5}{3}[/tex]
5 -3 -3 - (-5) = 2 2 - (-2) = 4 [tex]\frac{-3}{-5}=\frac{3}{5}[/tex]
This table depicts,
1). Ist difference is not common
2). IInd difference is common
3). Ratio is not common
Therefore, this table represents a quadratic function because the second difference are all the same value.
Option (4) will be the answer.

19. Find the equation of the line that contains the given points. Write the equation in slope-
intercept form, if possible.
(-5,-5) and (1,7)
Please solve step by step
Answer:
y = 2x +5
Step-by-step explanation:
1. use slope intercept for y2 - y1 / x2 - x1 --> 7-(-12) / 1-(-5)
2. solve --> 7-(-12) / 1-(-5) = 2
3. put in slope (2) and a coordinate into equation --> y = mx + b --> 7 = 2(1) + b
4. solve --> 7 = 2(1) + b --> b = 5
5. put the equation together --> y = 2x + 5
