Answer:
The solution is (-17,80.5) and (1,8.5)
Step-by-step explanation:
Equation 1 : 
Equation 2: 
Substitute the value of y from equation 2 in equation 1
Equation 1 :
After substitution :
Substitute the value of x = -17
y = -4x+12.5
y = -4(-17)+12.5
y=80.5
Substitute the value of x = 1
y = -4(1)+12.5
y=8.5
Hence the solution is (-17,80.5) and (1,8.5)
Answer:
No
Step-by-step explanation:
The slope of the equation is y = 2x + 3 is 2.
Find the slope of the points.
m = y₂ - y₁ / x₂ - x₁
m = 1 - 7 / 1 - (-2)
m = -6 / 3
m = -2
The same slope will happen if you also calculate for the third point.
As you can see. The slopes are not the same for one is rising (positive) while the other is fall (negative).
I believe the answer is B. 3
Answer:
yes
Step-by-step explanation:
f the exterior angle of a polygon is given, then the formula to find the interior angle is Interior Angle of a polygon = 180° – Exterior angle of a polygon Method 3: If we know the sum of all the interior angles of a regular polygon, we can obtain the interior angle by dividing the sum by the number of sides
The next number would be 493
