Step-by-step explanation:
7m+19/2=13
7m +19 = 13 x 2
7m = 26 - 19
m = 7/7 = 1
Another way :
7m+19/2=13
7m = 26/2 - 19/2
7m = 7
m = 7/7 = 1
Both ways r correct !!
I hope im right!!

Giselle pays $210 in advance on her account at the athletic club. Each time she uses the club, $15 is deducted from the account. Model the situation with a linear function.
b = 195 – 15x
b = 210 + 15x
b = 195 + 15x
b = 210 – 15x

In each of the following graphs, the two given polygons are similar. Write precisely a single dilation (coordinates of center and coefficient) by which the image (labeled with primed letters) was obtained. Will Give Brainiest!!!!!
Answer:
Center: (0,0) coefficient: [tex]\frac{1}{3}[/tex]
Step-by-step explanation:
The side of the smaller polygon is 1/3 the size of the larger one, and that is why the coefficient is 1/3.
Polygon MNPQ was dilated by a scale factor of 1/3 and center of dilation (0, 0) to create M'N'P'Q'.
What is dilation?Dilation is the increase or decrease in the size of a figure by a scale factor of k, thereby creating an image.
From the diagram:
Scale factor = N'P' / NP = 2/6 = 1/3
Center = (0, 0)
Polygon MNPQ was dilated by a scale factor of 1/3 and center of dilation (0, 0) to create M'N'P'Q'.

I need help , I really don’t understand it .
Answer:
slope intercept form is the form of y=mx+b, where the slope is m and the y intercept is b.
what you have to do is to solve the equations for y.
1) 2x+2y = 10
2y = 10 -2x
y = -x +5
2) 12+4y = -4x
4y = -4x-12
y = -x -3
lines are parallel when they have same slope and different y-intercepts. m1=m2 and b1 ≠ b2
lines are perpendicular when the multiplication of their slope gives -1
m1 x m2 = -1
here the slopes are same and y-intercepts are different so lines are parallel.

tell me if the statement below is sometimes, always, or never true. justify your reasoning, (the Expressions x - 3 + y -3 represent the same value.)
Answer:
Sometimes true. It may be true at times if x or y equal each other, but if they do not equal each other it is not true
Step-by-step explanation:
We are given two expressions: x -3 and y - 3
Here x and y are two different variables.
These expressions are equal, when the value of x and the value of y are equal.
x - 3 = y -3 if x = y.
Therefore, the two expressions have the same value in sometimes.
That is, when x = y, then the value of two expressions are the same.
Example.
If x = 2 and y = 2, then
x - 3 = y - 3
2 - 3 = 2 - 3
-1 = -1
If they have different values, for x = 2 and y = 3
x - 3 = y - 3
2 - 3 = 3 -3
-1 = 0
Which is not true.
Therefore, the answer is sometimes.
