Answer:
-2, -6
Step-by-step explanation:
using cramer rule
5 -3
-2 -1
calculatiing the determinant = (5 x-1) - (-3x-2) = -5 -(6) = -5-6=-11
using cramer rule
to calculate x we change the coefficient of x with the answer (8,10)
8 -3
10 -1
we calculate determinant = (8x-1)-(-3x10) = -8-(-30) = -8+30 =22
to calculate x
22/-11= -2
to calculate y we change the coefficient of y with the answer (8,10)
5 8
-2 10
we calculate determinant = (5x10)-(8x-2) = 50 -(-16) = 50 +16=66
to calculate y
66/-11= -6
Answer:
Is non-linear
Step-by-step explanation:
It is a quadratic function
A single appliance has 6 widgets, and a widget has 7 bolts. Therefore, you need to multiply 6 by 7 to find the number of bolts in a single appliance.
6 x 7 = 42
Now that you know the number of bolts in an appliance, you can find the number of bolts in 20 appliances by multiplying 42 by 20.
42 x 20 = 840
Hence, there are 840 bolts in 20 appliances.
Answer:
y = 0.5x + 50.95
Step-by-step explanation:
Given y is total cost while x is total miles
Slope: m = (y2-y1)/(x2-x1)
m = (75.95-65.95)/(50-30) = 10/20 = 0.5
y = mx + b
y = 0.5x + b
75.95 = 0.5(50) + b
b = 50.95
Slope intercept form: y = 0.5x + 50.95
