I think it’s c?
Answer:
B. f(x) = -x + 2
Step-by-step explanation:
First, you find the point on the y-axis which is (0,2) in this problem.
This will be your b in y = mx+ b
Then, you'll find how many blocks you are moving or rise over run. Which is -1/1 or -1.
This will be your m in y = mx + b
But we don't write the 1 so it will just be -x
Now add all your numbers in the standered form (y = mx + b) to get y = -x + 2 or f(x) = -x + 2

y- 4/5=1
what does y equal to?
Answer:
y=1.8
Step-by-step explanation:
first change the fraction into a decimal.
4/5 =0.8
plus the 0.8 to both sides
y=1.8
Answer:
[tex]y - \frac{4}{5} + \frac{4}{5} = 1 + \frac{4}{5} \\ y = \frac{5 + 4}{5 } \\ y = \frac{9}{5} [/tex]

Brooke multiplied 3 and 9 and got 17 Brooke knows her answer is wrong because she know it should be approximately
Answer:
Kindly check explanation
Step-by-step explanation:
If Brooke multiplied 3 by 9 and obtained 17 ; then Brooke is definitely wrong
3 * 9 = exactly 27
However, for approximation sake ;
We could round 9 to 10 ; and multiply 10 by 3
10 * 3 = 30 ; this gives an approximate solution for the multiplication problem ;
3 * 9 = exactly 27 or approximately 30

in a bowl there are 20 Hershey bars and 50 bags of skittles. what is the ratio of skittles to hershey bars in the bowl
Answer:
5:2 or in other words 5 to 2
Step-by-step explanation:
The original ratio would be 50:20, but we can divide both sides by 10 to simplify our answer to 5:2.
Answer:
5:2 Or 50:20 (5:2 is the simplified version)
50 bags of skittles to 20 Hershey bars (what it looks like with words)

Factor the expression
15x+35y
Answer:
5(3x+7y)
Step-by-step explanation:
In able to factor, it would require to find the least common number between x and y. In this scenario, it would be 5.
Answer:
You're going to get 5(3x + 7y)
Step-by-step explanation:
Simplifying
15x + 35y
Factor out the Greatest Common Factor (GCF), '5'.
5(3x + 7y)
Final result:
5(3x + 7y)
Oceanside bike rental shop charges seventeen dollars plus seven dollars an hour for renting a bike. Jason paid eighty dollars to rent a bike. How many hours did he have to pay to have the bike checked out?
Answer:This is a linear equation.
y = mx+b
y is the total cost.
The slope m is the rate: that's 9 dollars per hour.
x is the number of hours.
b is the initial value: that's 16 dollars.
y = 9x+16
The problem states that the cost was 79 dollars.
Substitute that for y and solve for x.
79 = 9x+16
63 = 9x
x = 7 hour
Step-by-step explanation:
Answer:
9
Step-by-step explanation:
80-17=63
63/7 = 9
7 times 9 = 63

Function f approximately represents the trajectory of an airplane in an air show, where x is the horizontal distance of the flight, in kilometers. What is the symmetry of the function?
Answer:
[tex](\frac{3}{2},102)[/tex]
Step-by-step explanation:
Given
[tex]f(x)=88x^2-264x+300[/tex] --- Missing from the question
Required
The symmetry
First, we express f(x) as: [tex]f(x) = a(x - h)^2 + k[/tex]
Where the symmetry is: (h, y) and x = h
Equate f(x) to 0
[tex]88x^2-264x+300 = 0[/tex]
Subtract 300 from both sides
[tex]88x^2-264x+300 - 300= 0 - 300[/tex]
[tex]88x^2 - 264x= - 300[/tex]
Factorize
[tex]88(x^2 - 3x) = -300[/tex]
On the left-hand side, the coefficient of x is -3.
Divide by 2 and add the square to both sides.
So, we have:
[tex]88(x^2 - 3x) + (\frac{3}{2})^2 = -300 + (\frac{3}{2})^2[/tex]
Multiply the new terms by 88 (to make it factorizable)
[tex]88(x^2 - 3x ) +88* (\frac{3}{2})^2 = -300 + 88 * (\frac{3}{2})^2[/tex]
Factorize
[tex]88(x^2 - 3x + (\frac{3}{2})^2) = -300 + 88 * (\frac{3}{2})^2[/tex]
The quadratic expression in the bracket is a perfect square. This gives:
[tex]88(x - \frac{3}{2})^2 = -300 + 88 * (\frac{3}{2})^2[/tex]
[tex]88(x - \frac{3}{2})^2 = -300 + 88 * \frac{9}{4}[/tex]
[tex]88(x - \frac{3}{2})^2 = -300 + 22 * 9[/tex]
[tex]88(x - \frac{3}{2})^2 = -102[/tex]
Add 102 to both sides
[tex]88(x - \frac{3}{2})^2 +102= -102 + 102[/tex]
[tex]88(x - \frac{3}{2})^2 +102= 0[/tex]
Equate to y
[tex]y = 88(x - \frac{3}{2})^2 +102[/tex]
Recall that:
The symmetry is: (h, y)
By comparison with [tex]f(x) = a(x - h)^2 + k[/tex] and x = h
[tex]h = \frac{3}{2}[/tex]
So: [tex]x = \frac{3}{2}[/tex]
Substitute [tex]x = \frac{3}{2}[/tex] in [tex]y = 88(x - \frac{3}{2})^2 +102[/tex]
[tex]y = 88(\frac{3}{2} - \frac{3}{2})^2 +102[/tex]
[tex]y = 88(0)^2 +102[/tex]
[tex]y = 0 +102[/tex]
[tex]y = 102[/tex]
So, the symmetry is: [tex](\frac{3}{2},102)[/tex]

A store pays $22 for a surfboard. The store marks up the price by 37%. What is the amount of the mark-up?
Answer:
$8.14
Step-by-step explanation:
Given data
Cost of surfboard= $22
Mark up = 37%
Required
