HELP ME PLEASE!!! 2(b+3)-(7+b)=-7 ??
2(b + 3) - (7 + b) = -7
2b + 6 - 7 - b = -7
b = -6 + 7 - 7
b = -6
To solve this first distribute the 2, and then distribute the negative sign.
2(b+3)-(7+b)=-7
2b+6-7-b=-7
Combine like terms.
2b+(-b)=b
6+(-7)=-1
b-1=-7
Add 1 on both sides of the equation.
b-1+1=-7+1
b=-6

What is your question exactly??
the parent function of a quadratic equation is vertically stretched by a factor of 2, then translated 5 units to the right and 1 unit down. write the equation of the new function in vertex form
A vertical stretch appears as a multiplier for the function value. Translation right appears as a value subtracted from the independent variable. Translation up appears as a value added to the function value.
For function f(x), stretching by a factor of 2, then translation 5 right and -1 up will give the function
... g(x) = 2f(x-5) -1
When f(x) = x², this becomes ...
... g(x) = 2(x -5)² -1
... g(x) = 2x² -20x +49
The equation of the new function in vertex form after the parent function of a quadratic equation is vertically stretched by 2, translated 5 units to the right and 1 unit down is y = 2(x - 5)^2 - 1.
Explanation:The parent function of a quadratic equation is given by f(x) = x^2. When it is vertically stretched by a factor of 2, it becomes 2f(x) = 2x^2. 5 units translation to the right will give f(x - 5) = 2(x - 5)^2 and a 1 unit downward shift gives f(x) = 2(x - 5)^2 - 1. Therefore, the equation of the new function in vertex form is y = 2(x - 5)^2 - 1.

Given polynomial is:
[tex]-12x^{5}-6 x^{4}+5 x^{3}-x^{2}-12x+9[/tex] ..... Lets say it is "a"
We have to subtract a polynomial from this above one, to get the answer as:

Three friends all have same ages that are consecutive integers. The sum of their ages is 180. What is the age of the oldest friend?
a) 61
b) 59
c) 62
d) 60
Answer:
a) 61
The friend's ages are consecutive, therefore they are each one year apart. There are 3 friends whose ages add up to 180 in total.
[tex]180 / 3 = 60[/tex]
In order to make three consecutive numbers, subtract one and add one to 60.
[tex]60 - 1 = 59\\60 + 1 = 61[/tex]
You get 59, 60, and 61.
61 is the oldest age, that's your answer.

The graph of function g is a vertical stretch of the graph of function f by a factor of 3. Which equation describes function g?
g(x)=f(x3)
g(x)=3f(x)
g(x)=13f(x)
g(x)=f(3x)
Answer: The correct option is second, i.e., [tex]g(x)=3f(x)[/tex].
Explanation:
A functions g(x) is stretch or compressed of graph of function f(x) is defined by the equation,
[tex]g(x)=kf(x)[/tex]
Where, k is a constant and it shows the compress or stretch factor.
If k>0, then it is a stretch factor and the graph of f(x) is stretched by factor of k.
If k<0, then it is a compress factor and graph of f(x) is compressed by factor k.
Since the graph of g(x) is a vertical stretch of the graph of function f(x) by a factor of 3, therefore,
[tex]g(x)=3f(x)[/tex]
So, the option second is correct.
to make a shade of plant called Jasper Green, Mix 4 quarts of green paint with 2/3 cups of black paint. how much green paint should be mixed with 4 cups of black paint to make Jasper Green?
Answer
24 quarts of green paint should be mixed with 4 cups of black paint.
That is (96 cups)
Step by step explanation
Jasper Green mix 4 quarts of green paint with 2/3 cups of black paint.
Let's convert 4 quarts into cups.
1 quart = 4 cups
4 quarts = 16 cups
Here mix 16 cups of green paint with 2/3 cups of black paint.
Let's use the proportion
Green paint Black paint
16 2/3
x 4
16/x =2/3 divided by 4
[tex]\frac{16}{x} = \frac{2/3}{4}[/tex]
Cross multiplying, we get
16*4 = 2/3 x
64 = 2/3 x
x = 64/(2/3)
x = 64 * 3/2
x = 192/2
x = 96 cups
96 cups of green paint should be mixed with 4 cups of black paint.
We can covert 96 cups into quarts by dividing by 4
96/4 = 24 quarts
24 quarts of green paint should be mixed with 4 cups of black paint.
Thank you.
To make Jasper Green with 4 cups of black paint, you need to create a proportional relationship and solve for the amount of green paint needed, which is 96 cups.
Explanation:To solve this, we need to set up a proportional relationship between the amounts of green paint and black paint. In the first mixture, we have 4 quarts of green paint for every 2/3 cups of black paint. Converting 4 quarts to cups (since 1 quart = 4 cups), we get 16 cups of green paint.
Then we can set up the proportion: (16 cups green / 2/3 cups black) = (x cups green / 4 cups black). Cross multiplying and solving for x, we get x = 96 cups of green paint. So, to make Jasper Green with 4 cups of black paint, you need to mix in 96 cups of green paint.

Nicole is running for school president. Her best friend designed her campaign poster, which measured 3 feet by 2 feet. Nicole liked the poster so much, she reproduced the artwork on rectangular buttons that measured 2 inches by 1 1/3 inches. What is the scale factor as a fraction (and how would I do this!?)
[tex]\frac{3 (ft)}{2(in)} by \frac{2(ft)}{\frac{4}{3}(in)}[/tex]
= [tex]\frac{3 (ft)}{2(in)} by \frac{2(3)(ft)}{4(in)}[/tex]
= [tex]\frac{3 (ft)}{2(in)} by \frac{3(ft)}{2(in)}[/tex]
Scale factor is: [tex]\frac{3(ft)}{2(in)}[/tex]
Answer:
9/16 is the scale factor.Step-by-step explanation:
Every transformation has an original figure and a transformed figure.
In order to find the scale factor fo the transformation, we need to divide the transformed dimensions by the original ones.
So, in this case, the poster originally had 3 feet by 2 feet. Then, the reproduced artwork has 2 inches by 1 1/3 inches. Before we divide, we need to transform feet to inches.
We know that 1 feet equals 12 inches, that means
[tex]3ft \frac{12in}{1ft} =36in[/tex]
[tex]2ft\frac{12in}{1ft}=24in[/tex]
Then, we do the divisions
[tex]\frac{36in}{2in}=18\\\frac{24in}{1\frac{1}{3}in }=\frac{24in}{\frac{4}{3}in }=\frac{96}{3}=32[/tex]
Therefore, the scale factor is [tex]\frac{18}{32}=\frac{9}{16}[/tex]

A T-shirt department store cost 7.50.the total cost in dollar of a T-shirt is givien by the function C(a)=7.5a
Given cost function C(a) = 7.5a, where a is the number of T-shirts.
Let us complete table.
We need to plug a=1,2,3,4 in above function to get the costs to complete the table.
For a =1
C(1)= 7.5(1) = 7.50
For a =2
C(2)= 7.5(2) = 15.00
For a =3
C(3)= 7.5(3) = 22.50
For a = 4
C(4)= 7.5(1) = 30.00
In order to find the common difference we need to find the diffrences of costs 15-7.50 = 7.50
22.50-15.00=7.50.
Therefore, common difference is 7.5.a represents the number of T-shirts.
Domain of a is the numbers we can take for a.
So, we can take value for a as 0 or greater value.
Therefore, domain for a would be a is gerater than or equal to 0.
