-7x - 2y = 19
4x + y = -12
Set y equal to each other (opposite signs are fine and you could also set x equal instead of y)
-7x - 2y = 19
8x + 2y = -76
Add equations together
x = -52
Plug x value into an equation
4(-52) + y = -12
Solve for y
-208 + y = -12
y = 196
Hope this helps! ;)
Answer:
or around 57.88
Step-by-step explanation:
We can find the base length by using the formula for the area of a triangle.

Plug in the values that we know, the area and the height, and solve for

6a^2 - 2 -6 a -5a = 0
6a^2 -11 a - 2 = 0
a = 2 , a= -1/6
Answer:
Step-by-step explanation:
This is an exponential function of the form F=Ir^t, in this case
t(x)=948(1-0.045)^x
t(x)=948(0.955^x)
So the first answer
