The value of x is -6, and the value of y is -34. You can figure this out by setting the two equations equal to each other, so it would look like: 5x-4 = 7x+8. Then, use the addition property of equality by adding 4 to both sides of the equation to leave x by itself. After, use the subtraction property of equality by subtracting 7x on both sides to get x by itself. Finally, use the division property of equality by dividing both sides of the equation by 2, to get x by itself. This will give you the value of x or -6. To get the y value, simply substitute x into the original equations.

Hope this helps ^-^

What is the term, coefficient, constant, and factor of 1/2(base1 + base2)h? (Formula used to find area of trapezoid)

vovangra [49]

Answer:

i. Term = $\frac{b_{1}h }{2}$ + $\frac{b_{2}h }{2}$

ii. Coefficient = $\frac{1}{2}$

iii. Constant = $\frac{1}{2}$

iv. Factor = $\frac{h}{2}$

Step-by-step explanation:

A trapezoid is a quadrilateral which has its base parallel to the opposite side. It's area can be determined by;

Area of trapezium = $\frac{1}{2}$ ( $b_{1}$ + $b_{2}$ )h

Where $b_{1}$ is the measure of length of its fist base, $b_{2}$ is the measure of its second base and h is its height.

Considering the given question,

Term = $\frac{b_{1}h }{2}$ + $\frac{b_{2}h }{2}$

Coefficient = $\frac{1}{2}$

Constant = $\frac{1}{2}$

Factor = $\frac{h}{2}$
