-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

Answer:
It would be 80 miles in 1 hour
Step-by-step explanation:
You divide 560/7
7 goes into 56, 8 times and into 0, 0 times.
560/7=80
Answer:
a) Triangle.
b) Triangle.
c) The area is 110 cm.
Step-by-step explanation:
The shape is given because it is a cross section of a Pyramid which we can see shaded in grey.
The area is given by the base times hight devided by 2. So 10cm * 22cm/2= 110cm.
Hope this helped ;)
Yes because there are no constants after
In analytical geometry, we can find the linear distance between two parallel lines by determining the coefficients of the variables and the constants. The general equation for a linear equation is: Ax + By = C.
Line 1: 2x - 3y = -4
Line 2: 2x - 3y = -15
In this case, A=2 and B=-3. The constants are C₁ = -4 and C₂ = -15. The distance follows this formula:
d = |C₁ - C₂|/(√(A²+B²)
d = |⁻4 - ⁻15|/(√(2²+⁻3²)
d = 3.051 units
