If the vertex of f(x) is (-9,-7), what is the vertex of f(x-5)+3?
Answers
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:

2 right triangles have identical angle measures but different side lengths. The first triangle has side lengths of 6, 10, 8 and the second triangle has side lengths of 3, 5, 4. Which transformation maps the large triangle onto the small triangle?
Answers
Answer:
The transformation is 0.5
Step-by-step explanation:
The lengths of the second triangle is just half the length of the first triangle, from the center. As it is just resizing, the angles would not change, resulting in the same triangle, except for size.

The temperature of a place was 32⁰C on Friday. On Saturday it rose by 4⁰C, then rainfall on Sunday caused the temperature to fall by 7⁰C. What was the final temperature on Sunday?
Answers
Given :
The temperature of a place was 32⁰C on Friday. On Saturday it rose by 4⁰C, then rainfall on Sunday caused the temperature to fall by 7⁰C.
To Find :
The final temperature on Sunday.
Solution :
Temperature on Saturday = initial temperature + 4⁰C
= 32⁰C + 4⁰C
= 36⁰C.
Temperature on Sunday = temperature on Saturday - 7⁰C
= 36⁰C - 7⁰C
= 29⁰C
Therefore, final temperature on Sunday is 29⁰C.
Hence, this is the required solution.
Graph a line that contains the point (3,-6) and has a slope of
2

Answers
Answer:
[tex]\boxed {\boxed {\sf y= 2x-12}}[/tex]
Step-by-step explanation:
We are given a slope and a point, so we can use the point-slope equation.
[tex]y-y_1=m(x-x_1)[/tex]
where m is the slope and (x₁, y₁) is the point.
The slope is 2 and the point is (3,-6).
[tex]m= 2\\x_1=3 \\y_1=-6[/tex]
Substitute the values into the formula.
[tex]y--6=2(x-3)[/tex]
[tex]y+6=2(x-3)[/tex]
Distribute the 2 on the right side of the equation.
[tex]y+6=(2*x)+(2*-3)[/tex]
[tex]y+6=2x-6[/tex]
We want to get the line into the form: y=mx+b. We have to isolate y on one side of the equation. 6 is being added to y. The inverse of addition is subtraction; subtract 6 from both sides of the equation.
[tex]y+6-6=2x-6-6[/tex]
[tex]y=2x-6-6[/tex]
[tex]y=2x-12[/tex]
The line is y=2x-12 (slope=2 and y-intercept=-12)

Write an equation in slope-intercept form with the following information. Goes through the points (6, 2) and (7, 5).
Slope= _____ y-intercept=_____
Answers
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

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
Answers
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

17 What are the x-intercept to the function f(x)=2x-31+2 ?
A {0}
B{-5/2,5/2}. C{ } D{-5/2,-1/2}
Answers
Answer:
See below
Step-by-step explanation:
It seems to be a typo.
[tex]f(x)=2x-31+2[/tex]
[tex]f(x)=2x-29[/tex]
The x-intercept is when the function is equal to zero. Once the function is linear, there will be one x-intercept.
[tex]0=2x-29[/tex]
[tex]x=\dfrac{29}{2}[/tex]
Once there are alternatives with two values, your function is probably a quadratic function.
[tex]f(x)=2x^2-31x+2[/tex], but the roots are not in the alternatives.

Given :
Phil sold 11 small boxes and 10 large boxes of tangerines for a total of $146.
Nick sold 5 small boxes of tangerines and 12 large boxes of tangerines for a total of $126.
To Find :
The price of each small box and large box.
Solution :
Let, price of small box is x and large box is y.
Mathematical expression of given equations :
11x + 10y = 146 ...1)
5x + 12y = 126 ...2)
Solving above equation, we get :
x = 6 and y = 8
Therefore, price of small and large box is $6 and $8 respectively.
Hence, this is the required solution.

Question Blank

Plz due 11:59
Answers
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.
