Answer:
subtraction
Step-by-step explanation:
its subtraction because if you do 62.5-2.5 it = 60 and then 60-2.5=57.5 57.5-2.5=55 55-2.5=52.5 52.5-2.5=50 50-2.5= 47.5 47.5-2.5 = 45 s so it was 7 or 8 years ago idk count them see how many times i did it
f(x)=5(1+0.25)^x,f(4)
Please show step by step of how you got the answer
Answer:
f(4) = 12.2
Step-by-step explanation:
we are given that x = 4, plug in 4 into the equation
f(4) = 5(1+0.25)^(4)
f(4) = 5(1.25)^(4)
raise 1.25 to the 4th, which is equal to 2.44
f(4) = 5(2.44)
f(4) = 12.2

Select the correct answer. Celeste can spend no more than $30 to quinoa and rice. She will pay $5 per pound for quinoa and $2 per pound for rice. which graph best represents the number of pounds of quinoa and the number of pounds of rice celeste can buy?
Answer:
5x+2y<=30
Step-by-step explanation:
Inequalities help us to compare two unequal expressions. The graph for the inequality can be made as shown below.
What are inequalities?Inequalities help us to compare two unequal expressions. Also, it helps us to compare the non-equal expressions so that an equation can be formed. It is mostly denoted by the symbol <, >, ≤, and ≥.
As per the graph let the number of pounds of quinoa be represented by x and the number of pounds of rice Celeste can buy be represented by y.
Therefore, the expression that can represent the number of pounds that Celeste can buy is,
5x + 2y
Also, it is given that Celeste can spend no more than $30. Therefore, the inequality can be written as,
5x + 2y ≤ 30
Now the graph for the inequality can be made as shown below.

Solve 4 - x= -8.
Correct answer please
Answer:
12!
Step-by-step explanation:
Heya! What you're searching for is the value of x that would bring you to -8. 4 minus the value of x is what would get you to -8, so I simply plugged 12 in for the value of x. 12 subtracted from 4 gives you -8, so I hope that this helped! (Please mark as brainliest if I was right <3)
Answer:
X = 12Step-by-step explanation:
4 - x = -8

Grace was driving down a road and after 4 hours she had traveled 66 miles. At this speed, how many miles could Grace travel in 8 hours?
Fill out the table of equivalent ratios until you have found the value of x.
Answer:
132 miles
Step-by-step explanation:
4 is half of 8 so you just have to multiple everything by 2 to get your answer
Answer:
132
Step-by-step explanation:
Since in four hours you can travel 66 miles, 8 hours would be 66x2, which is 132.
1hour=16.5
2hour=33
3hour=49.5
4hour=66
5hour=82.5
6hour=99
7hour=115.5

We can write equation in the form of [tex]y=mx+b[/tex]
where m is slope and b is y-intercept.
Finding Slope
We can used the slope formula to find slope: [tex]Slope=\frac{y_2-y_1}{x_2-x_1}[/tex]
From the table we have: [tex]x_1=3, y_1=-5, x_2=7, y_2=-2[/tex]
Putting values and finding slope
[tex]Slope=\frac{y_2-y_1}{x_2-x_1}\\Slope=\frac{-2-(-5)}{7-3} \\Slope=\frac{-2+5}{7-3}\\Slope=\frac{3}{4}[/tex]
So, we get slope [tex]m=\frac{3}{4}[/tex]
Now, finding y-intercept
Using the slope [tex]m=\frac{3}{4}[/tex] and point (3,-5) we can find y-intercept
[tex]y=mx+b\\-5=\frac{3}{4}(3)+b\\-5=\frac{9}{4}+b\\b=-5-\frac{9}{4}\\b=\frac{-5*4-9}{4}\\b=\frac{-20-9}{4}\\b=\frac{-29}{4}[/tex]
The y-intercept is [tex]b=\frac{-29}{4}[/tex]
So, the equation having slope [tex]m=\frac{3}{4}[/tex] and y-intercept [tex]b=\frac{-29}{4}[/tex] will be:
[tex]y=mx+b\\y=\frac{3}{4}x-\frac{29}{4}[/tex]
The required equation is: [tex]\mathbf{f(x)=\frac{3}{4}x-\frac{29}{4}}[/tex]
which ordered pair makes both of these equations true?
A. (-9,25)
B. (-3,-13)
C. (2,-3)
D. (3,-1)
E. (9,11)
Answer:
D. (3, -1)
Step-by-step explanation:
y = 2x - 7 and 4x + y = 11 are two given equation
Now, Name the equation
y = 2x - 7 ...(1)
4x + y = 11 ...(2)
Then, Put the value of y in equation (2)
4x + y = 11
4x + (2x - 7) = 11
4x + 2x - 7 = 11
6x - 7 = 11
6x = 11 + 7
6x = 18
x = 18/6
x = 3
Here, put the value of x in equation (1)
y = 2x - 7
y = 2(3) - 7
y = 6 - 7
y = - 1
Thus, (3, - 1) pair makes both of these equations true

The value of €24 in pounds is 18 pounds or £ 18
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the value of £3 be = €4
So , the equation will be
The value of €1 = £ ( 3/4 )
So , the value of €24 is calculated by the equation
The value of €24 in pounds = value of €1 x 24
Substituting the values in the equation , we get
The value of €24 in pounds = £ ( 3/4 ) x 24
The value of €24 in pounds = £ 3 x 6
The value of €24 in pounds = £ 18
Therefore , the value of €24 in pounds is £ 18
Hence , The value of €24 in pounds is 18 pounds or £ 18

When you graph an inequality, you used a closed dot when you use which
symbols?
You should only use a closed dot for the symbols ≤ and ≥.
When you should use a closed dot?
There are two types of dots used when graphing inequalities, closed and open.
We use closed dots when the value where the dot is, is a solution.We use open dots when the velue where the dot is, is not a solution.So, for exampe in:
x > 3.
We would put an open dot at 3, because the value x = 3 is not a solution, but all the values at the right of the 3 are solutions.
In the other hand, for:
x ≥ 3
Now 3 is in fact a solution, so here we should use a closed dot.
Then, answering the question.

Answer:
[tex](f\circ g)(x)=x^2+9x+20[/tex]
Step-by-step explanation:
We have the two functions:
[tex]f(x)=x^2+5x+6\text{ and } g(x)=x+2[/tex]
And we want to find:
[tex](f\circ g)(x)[/tex]
This is equivalent to:
[tex](f\circ g)(x)=f(g(x))[/tex]
Therefore, we will have:
[tex]f(x+2)[/tex]
By substitution:
[tex]f(x+2)=(x+2)^2+5(x+2)+6[/tex]
Simplify. Square and distribute:
[tex]f(x+2)=(x^2+4x+4)+(5x+10)+6[/tex]
Rearrange:
[tex]f(x+2)=(x^2)+(4x+5x)+(4+10+6)[/tex]
Combine like terms:
[tex]f(x+2)=(f\circ g)(x)=x^2+9x+20[/tex]
