Answer:
(1, - 6 )
Step-by-step explanation:
Given the 2 equations
y = x - 7 → (1)
y = - 4x - 2 → (2)
Substitute y = x - 7 into (2)
x - 7 = - 4x - 2 ( add 4x to both sides )
5x - 7 = - 2 ( add 7 to both sides )
5x = 5 ( divide both sides by 5 )
x = 1
Substitute x = 1 into either of the 2 equations for corresponding value of y
Substituting x = 1 into (1)
y = 1 - 7 = - 6
Solution is (1, - 6 )
Answer:
-1/2
Step-by-step explanation:
(y2-y1)/
(x2-x1) (-2-2)/(3-(-5))
Nothing multiplies into 12 and adds into 17. Factors of 12 are 1,2,3,4,6, and 12. None of those add up to 17.
Answer:
A) 4
Step-by-step explanation:
Area of a triangle formula:
A = 0.5bh
Given:
b = 4
h = 2
Work:
A = 0.5bh
A = 0.5(4)(2)
A = 2(2)
A = 4
Answer:
36 square feet
Step-by-step explanation:
To get the answer you need to find the area of the triangle and subtract area of the rectangle.
7*12/2 = 42
42 - 3*2 = 36
