The answer is (-1,7)

I got this answer because to solve a system, you find the point on the graph where both lines intersect. And that point in this graph is (-1,7). Hope this helps!:)))))

(05.01)Which equation can be used to calculate the area of the shaded triangle in the figure below?
Marina86 [1]

Equation of shaded triangle is \frac{1}{2} (14\times8).

Solution:

Length of the rectangle = 14 ft

Breadth of the rectangle = 8 ft

Area of the rectangle = length × breadth

                                    = 14 × 8

In this rectangle the diagonal splits the rectangle into two equal halves.

Area of the shaded triangle = Half of area of rectangle

                                              $=\frac{1}{2} (14\times8)

Area of the shaded triangle = \frac{1}{2} (14\times8)

Hence the equation can be used to calculate the area of the shaded

triangle is \frac{1}{2} (14\times8).

Find the midpoint of A and B where A has coordinates (-7, 1)<br> and B has coordinates (3,-5).
zepelin [54]

Answer:

A (-7, 1) = (X1, Y1)

B (3, -5) = (X1, Y2)

Now,

Mid point = (X1 + X2÷2, Y1 + Y2 ÷ 2)

= {-7+3÷2, 1+(-5)÷2}

= (-4÷2, 1-5÷2)

= (-4÷2, -4÷2)

= (-2, -2)

Step-by-step explanation:

I hope it will help you to study.
