Write an equation in slope-intercept form with the following information. Goes through the points (6, 2) and (7, 5).
Slope= _____ y-intercept=_____
Answer:
The slope is 3
y-intercept is -16
Step-by-step explanation:
Let's start by using the slope formula, [tex]m=\frac{y2-y1}{x2-x1}[/tex]
plug in the points for the relating x and y and solve,
[tex]m\frac{5-2}{7-6}[/tex] this simplifies to [tex]\frac{3}{1}[/tex] or "3"
we have our slope: 3/1 or "3"
the equation needed to find the y-intercept is y=mx+b
We will need to solve for "b" to figure out the y-intercept.
let's plug in any pair of x and y, i'll just choose (6,2)
2=3(6)+b, 2=18+b, 2-18=18-18+b, -16=b
Y-intercept is -16

If the vertex of f(x) is (-9,-7), what is the vertex of f(x-5)+3?
Answer:The vertex is
(0,7)
Sometimes we have problems with the easier questions because it's not exactly in the form we're used to. Normally for a quadratic, you would complete the square to find the vertex. But this quadratic is already in vertex or standard form:
f(x)=−(x−0)2+7

Given that two sides of a triangle have sides 5 and 7, write the range of the lengths of the third side:
Question Blank
type your answer...
< x
<
Question Blank
type your answer...
Plz due 11:59
Answer:
Step-by-step explanation:
The two sides add up to 12. If the third "side" of the triangle is 12, then 5 and 7 will lie horizontally on 12.
So the maximum value must be less than 12. What's the smallest x could be?
well 5 + something must be > than 7. If they are not larger than 7, then 5 and something will lie on 7 just as it did before. So how big is something?
5 + y > 7
5 - 5 + y > 7 - 5
y > 2
So the range is 2 < x < 12
How else could you write this?
2 < x
x < 12 is one way.

What is the length of DE and the length of AB
Answer:
DE = 15, AB = 6
Step-by-step explanation:
Because the triangles are similar, that means that the sides are proportional to each other. The ratio of CE to AC is 24/8 which is 3. That means that each length of the small triangle is 3 times smaller than the same side on the larger triangle.

1. Natoy's rectangular swimming pool has the length of 3m more than thrice its
width. What are the dimensions of the pool if it has an area of 216m2?
Width (w)
Length (/) = 3w + 3
Answer:
Step-by-step explanation:
Given
Natoy's rectangular swimming pool has the length of 3m more than thrice its
width.
Width=w
Length =3w+3
So
Area of the rectangular swimming pool=length×width
216=(3w+3)×w
216=3w^2+3w
3w^2+3w-216=0
3(w^2+w-72)=0
W^2+w-72=0
W^2+(9-8)w-72=0
W^2+9w-8w-72=0
W(w+9)-8(w+9)=0
(W+9)(w-8)=0
Sotwo value of w are 8,-9
We take positive value for rectangular swimming so we take w=8m
Width=8m
Length=3×8+3
= 24+3
=27m
