Answer:</h3>
y = -1/2x +(4 1/2)
<h3>
Step-by-step explanation:</h3>
The two marked points (-1, 5) and (1, 4) differ in y-value by -1 and x-value by +2, so the slope is -1/2.
The y-intercept is halfway between the marked y-values, so is at 4 1/2.
Putting these numbers into the slope-intercept form of the equation for a line, ...
... y = mx + b . . . . for slope m and y-intercept b
we have ...
... y = -1/2x +(4 1/2)
Answer:
the value of this is-217÷4 = -54.25
This is a stupid question. The teacher who asked this needs to go back to school.
A = x⁴ - 9y²
That's going to be a number. As long as it's positive we can choose any length for our rectangle L and we can compute the width by W=A/L. So the correct answer is the dimensions are L by (x⁴ - 9y²)/L.
They don't want the correct answer. They want you to factor this expression. We'll do it, but don't believe for a second this factoring somehow constrains the possible dimensions of some rectangle.
We use the difference of two squares, a²-b² = (a+b)(a-b)
A = x⁴ - 9y² = (x²)² - (3y)² = (x²+3y)(x²-3y)
Answer: x²+3y by x²-3y
Answer: The midpoint of AB should be (3,8)
Explanation: Try drawing the triangle using the information given and find the midpoint of AB then measure it
The pic is not drawn to scale but just to get an idea
0.99 x 24 = 23.76 assuming there is no tax.
