The graph of the quadratic function shown on the left is
y = –0.7(x + 3)(x – 4).
The roots, or zeros, of the function are
.
Determine the solutions to the related equation
0 = –0.7(x + 3)(x – 4).
The solutions to the equation are x =
.
Explanation:
We'll use the zero product property. This is the idea where if A*B = 0, then either A = 0 or B = 0.
So if
-0.7(x+3)(x-4) = 0
then either
x+3 = 0 or x-4 = 0
Both of those equations solve to
x = -3 or x = 4
The roots are the locations of the x intercepts, which is where the graph crosses or touches the x axis.

Riley earned $5 for 1 2 of an hour babysitting. What is her hourly rate? Simplify your answer and write it as a proper fraction, mixed number, or whole number.
Answer:
Riley's hourly rate is $10
Step-by-step explanation:
Riley earned $5 for 1/2 of an hour babysitting. What is her hourly rate?
1/2 of an hour = $5
1 hour = $x
Cross Multiply
1/2 × x = $5 × 1
x = $5 ÷ 1/2
x = $5 × 2
x = $10
Hence, Riley's hourly rate is $10

For triangle ABC with A=103, B=24, a=16, find angle C
Answer:
given A=103° , B=24°
In triangle ABC,
A+B+C=180° [angle sum property of triangle]
103°+24°+C=180°
127°+C=180°
C=180°-127°
C=53°

What percent is 14 of 20?
SHOW UR WORK
Answer:
14 is 70% of 20
Step-by-step explanation:
1. We assume, that the number 20 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 100% equals 20, so we can write it down as 100%=20.
4. We know, that x% equals 14 of the output value, so we can write it down as x%=14.
5. Now we have two simple equations:
1) 100%=20
2) x%=14
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
100%/x%=20/14
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
7. Solution for 14 is what percent of 20
100%/x%=20/14
(100/x)*x=(20/14)*x - we multiply both sides of the equation by x
100=1.42857142857*x - we divide both sides of the equation by (1.42857142857) to get x
100/1.42857142857=x
70=x
x=70
now we have:
14 is 70% of 20

Answer:
4^2+2^2, 5^2, 6^2-6
Step-by-step explanation:
4 to the power of 2 is 16 and 2 to the power of 2 is 4. 16+4 is 20.
5 to the power of 2 is 25 which is greater than 20.
6 to the power of 2 is 36 minus 6 is 30 which is greater than 25 and 20.
Michael charges a flat rate of $25 plus $20 per hour, x, to service air conditioners. The total cost Michael charges is f(x). [3 points]
A) What does the independent and the dependent variables represent?
Independent __________________________________
Dependent ____________________________________
B) Write a function rule in function notation for the total cost of his services, for x hours.
Function Rule _____________________________
Show work and answer throughly
Part (A)
Answers:
Independent Variable = x = number of hours
Dependent Variable = f(x) = total cost in dollars
---------------------------------
Explanation:
The independent variable is always x. When dealing with time, the time value is often the independent variable as time does its own thing. It marches on without any influence or external factors to change it.
On the other hand, the total cost is affected by time. The more time goes on, the higher the total cost will be. We say the total cost is dependent on the time. The dependent variable is always y, which can be replaced with f(x). In short, y = f(x).
===========================================================
Part (B)
Answer:
f(x) = 20x + 25
----------------------------------
Explanation:
The flat rate of $25 represents the initial cost. This is the cost if x = 0 hours of work is done. So this is the cost to get in the door, so to speak. You can think of this as the parts cost (from "parts and labor").
On top of that initial cost is the cost of $20 per hour. This can be thought of as the labor cost. If a job takes 1 hour to do, then we add on $20 to the flat rate of $25. If it takes 2 hours, then we add on 2*20 = 40 dollars. And so on. For x hours, we add on 20x dollars. Whatever x is, we multiply by 20.
So overall we have a flat rate of $25 and a variable rate of 20x dollars giving a total cost of f(x) = 20x+25
As a check, plugging x = 0 should lead to f(x) = 25
Plugging x = 1 should lead to f(x) = 20+25 = 45
And so on.

A box of cereal states that there are 90 calories in a 3 4-cup serving. What is the unit rate for calories per cup? How many calories are there in 2 cups of the cereal?
Answer:
Calories per cup = 120 calories
Calories in 2 cups = 240 calories
Step-by-step explanation:
Given that:
Number of calories in a [tex]\frac{3}{4}^{th}[/tex] cup serving = 90 calories
To find:
Unit rate for calories per cup = ?
Number of calories in 2 cups of cereal = ?
Solution:
Here we are given the number of calories in a [tex]\frac{3}{4}^{th}[/tex] cup serving.
To find the calories in one cup, we need to divide 90 calories with [tex]\frac{3}{4}[/tex].
So, unit rate for calories per cup can be given as:
[tex]\dfrac{90}{\frac{3}4}\\\Rightarrow \dfrac{90}{3}\times 4\\\Rightarrow \bold{120 \ calories}[/tex]
To find the calories in 2 cups of cereal, we need to multiply the unit rate for calories per cup with 2.
So, calories in 2 cups of cereal = [tex]120 \times 2[/tex] = 240 calories
Therefore, the answer is:
Calories per cup = 120 calories
Calories in 2 cups = 240 calories

find the range value of x which satistfy inequality (x + 2)² > 2x + 7
Answer:
the range value of x which satisfy inequality [tex](x + 2)^2 > 2x + 7[/tex] is [tex]\mathbf{x>1 \ or \ x<-3}[/tex]
Step-by-step explanation:
We need to find the range value of x which satisfy inequality [tex](x + 2)^2 > 2x + 7[/tex]
Solving:
[tex](x + 2)^2 > 2x + 7[/tex]
Using formula: [tex](a+b)^2=a^2+2ab+b^2[/tex]
[tex]x^2+4x+4>2x+7\\x^2+4x+4-2x-7>0\\x^2+4x-2x+4-7>0\\x^2+2x-3>0[/tex]
Now factoring the term: [tex]x^2+2x-3>0[/tex]
Breaking the middle term: 2x= 3x-x
[tex]x^2+2x-3>0\\x^2+3x-x-3>0\\x(x+3)-1(x+3)>0\\(x-1)(x+3)>0\\x-1>0 \ or \ x+3>0\\x>1 \ or \ x<-3[/tex]
So, the range value of x which satisfy inequality [tex](x + 2)^2 > 2x + 7[/tex] is [tex]\mathbf{x>1 \ or \ x<-3}[/tex]

Answer:
y = (-3/5)x - 7
Step-by-step explanation:
you are given the points (5,-10), (-10,-1)
a slope of (-1+10)/(-10-5) = -9/15 = -3/5 can be determined
using the point (0,-7), we can get y+7=(-3/5)(x - 0)
simplified: y = (-3/5)x - 7
