Answer:
P=9h
Step-by-step explanation:
Since Teresa makes 9 dollars for each hour of work, we can say:
9 dollars/1 hour.
Her total pay will be on one side of the equation:
p=
Since we do not know how many hours, we put the variable ‘h’ as it says in the problem in the hour section:
h hours
Every hour, she makes 9 dollars. Every ‘h’ hour, she makes 9xh or 9h dollars since you multiply the amount of money you get each hour by the number of hours. For example, if she worked 2 hours, you multiply 2x9 to get 18 dollars, which is what she earned in 2 hours.
p=9h

Write a quadratic function in standard form with zeros 5 and 6
Answer:
[tex] {x}^{2} - 11x +30[/tex]
Step-by-step explanation:
Zeros = 5 & 6
Let the variable of the quadratic function be x
Therefore, (x - 5) & (x-6) are factors
[tex](x - 5)(x - 6) \\ \\ = {x}^{2} - (5 + 6)x + ( - 5)( - 6) \\ \\ = {x}^{2} - 11x +30 \\ is \: the \: required \: quadratic \: \\function.[/tex]

Answer:
We can use a graphing calculator.
Step-by-step explanation:
To graph by hand, we simply write a table of values then graph the points in a coordinate plane.
Attached below is a graph of the equation.
evaluate the piecewise function
Answer:
f(-3)=-1
f(4)=7
f(-1)=-3
f(12) = -24
Step-by-step explanation:
Piecewise Functions
The piecewise functions define different pieces or subfunctions where the domain is divided into parts according to some conditions on the independent variable.
The pieces of the function are defined as shown below:
[tex]f(x)=\left\{\begin{matrix}-1 &x\le -2\\ 2x-1 &-2<x\le 4 \\ -3x+8 &x>4 \end{matrix}\right.[/tex]
Let's find the values of:
f(-3). Here the variable x is -3. We have to find the interval where x=-3 belongs. Since -3 ≤ -2:
f(-3)=-1
f(4). The variable x is 4 and it belongs to the second interval, thus
f(4)=2*4-1=7
f(4)=7
f(-1). x = -1. It belongs to the second interval, thus:
f(-1)=2*(-1)-1=-3
f(-1)=-3
f(12). x=12 belongs to the last interval since 12 > 4, thus:
f(12)= -3*12+8 = -36 + 8 = -24
f(12) = -24

1.) Angle 1 and angle 2 are complementary. If the measure of angle 1 is (8x - 6) and the measure of angle 2 is (14 + 8), find the value of x and the measure of angle 1.
Answer:
If the value of second angle is 14x + 8 then :
x = 4
angle 1 = 26°
Here is a table of the average distance and the variation in the distance for the five innermost planets in our solar system: Average Distance and Variation Planet Name Average Distance Variation Mercury 36.0 million miles 7.39 million miles Venus 67.2 million miles 0.43 million miles Earth 93.0 million miles 1.55 million miles Mars 142 million miles 13.2 million miles Jupiter 484 million miles 23.2 million miles "Average distance" means the mean distance that planet is from the sun over the course of its orbit, and "variation" means how far it varies from that mean. For example, if a planet had an average distance of 5 miles and a variation of one mile, it would have distances between 4 and 6 miles at different times. a) Write and solve an inequality to represent the range of distances that can occur between the Sun and one of the planets from the table (your choice). Show your steps/process. b) Why is this best represented as an inequality rather than an equation? Explain in at least 3 sentences.
9514 1404 393
Answer:
a) |e-93|≤1.55; 91.45 ≤ e ≤ 94.55
b) see below
Step-by-step explanation:
a) Let e represent the distance from the sun to the earth in millions of miles. The table tells us the average distance is 93.0 million miles, and the difference from that value can be as much as 1.55 million miles. The corresponding inequality is ...
|e-93.0| ≤ 1.55
We can solve this by rewriting it as a compound inequality.
-1.55 ≤ e -93.0 ≤ 1.55
91.45 ≤ e ≤ 94.55 . . . . . . add 93
__
b) An absolute value equation will give a finite number of particular values as its solution. The question asks for a range of values. An absolute value inequality is well-suited to providing a solution that is a range of values.

Which expressions have a value between 5 and 6?
Select all that are correct.
- pi+2
- square root of 24
- square root of 38
- square root of 26
- pi/2
Answer:
the expression that have the value of 5 and 6 is 17
The expression [tex](\pi + 2)[/tex] and [tex]\sqrt{26}[/tex] lies between 5 and 6.
Square root:The value of [tex]\pi=3.14[/tex]

What is the function rule?
Write the rule in function notation, using the slope-intercept form of a line.
Answer:
y = 2x - 5
Step-by-step explanation:
Okay. We have to get the slope first.
I'll be using points (3, 1) and (4, 3)
3 - 1
/
4 - 3
The slope is 2.
Now we can plug one of the points and the slope into point-slope form.
y - 1 = 2(x - 3)
y - 1 = 2x - 6
y = 2x - 5
Answer:
y=2x-5
(3, 1) and (4, 3)
