Answer:
y = 5x + 19
Step-by-step explanation:
y = 5x + b
4 = 5(-3) + b
4 = -15 + b
19 = b

<u><em>Answer:</em></u>45 ft</span>²<span> will be blue
<u><em>Explanation:</em></u><u>1- getting the area of the wall:</u>
area of the rectangle can be calculated as follows:
area = length * width
we are given that:
length = </span>
ft<span>
width = </span>
<span> ft
Now, substituting in the above rule, we can get the area as follows:
area = </span>
*
= 135 ft²<span>
<u>2- getting the area that would be pained blue:</u>
We are given that </span>
<span> of the area of the room would be painted blue, this means that:
area of blue = </span>
<span> * area of room
area of blue = </span>
<span> * 135
area of room = 45 ft</span>²<span>
Hope this helps :)</span>
a) For there to be a y-intercept of 3, when x=0, y=3.
- A. y=(0+1)(0-3)=-3
- B. y=0²-9=-9
- C. y=3(0)(0-3)=0
- D. y=(0+1)(0+3)=3.
So, the answer is D
b) For there to be roots of 0 and 3, there has to be factors of x and (x-3).
- The only choice that satisfies this is C
To know that a relation is a function is it the graph gets approved by the “vertical line text”. If the imaginary vertical lines you draw onto the graph only touch one part of the line, then it is a function. If they touch two or more parts of the line, then the relation isn’t a function.
(Since I cant see the following I’ll also give another tip) If the ordered pairs are given, then if a number in the x points is repeated, then it is not a function. But if I’m y is repeated, it doesn’t matter, it’s still a function. The only thing you need to focus on is on the x list, if one number is repeated then it is not a function.
Answer:
See attachment for diagram
Step-by-step explanation:
Given
Required
Draw the rectangle on a coordinate plane --- (missing from the question)
First, we calculate the distance between the given pairs.
So, the distance between the given pairs is 5 units... Let this be the length of the rectangle.
Using:
The width is 3 units.
This implies that the opposite sides of the rectangle are either 3 units down or 3 units up the given pairs.
Assume they are 3 units up.
