Answer:
Step-by-step explanation:
2x - 3 is a linear expression. y = 2x - 3 is the equation describing y.
If x = 1, y = 2(1) - 3 = -1
If x = 2, y = 2(2) - 3 = 1
and so on.
Isn't there more to this problem that merely "2x - 3"?
Answer:
-4
Step-by-step explanation:
8+4y= -8
4y= -8 -8
4y= -16
divide both sides by the coeffient of the variable. in this case divide both sides by 4
y=-4
Y equals 5 over 7x minus 5
The height is 24.
We can use Pythagorean’s Theorem: a^2+b^2=c^2
substituting values we get:
a^2+7^2=25^2
Solving we get:
a^2+49=625
a^2=576
a=24.
So the height is 24.
Hope this helps!
