Elsa works as a tutor for $15 an hour and as a waitress for $9 an hour. This month, she worked a combined total of 101 hours at her two jobs. Let tbe the number of hours Elsa worked as a tutor this month. Write an expression for the combined total dollar amount she earned this month.
Answer:
6t + 909
Step-by-step explanation:
t - tutor (hours)
101 - t = waitress (hours)
$15t + $9(101-t) = 15t + 909 - 9t

The sum of three consecutive odd integers is 459. What are the integers? (show your work please)
Answer:
151+153+155
Step-by-step explanation:
First you divide 459/3. That equals 153. Now you need 3 integers that add to 459. The first integer is 153 and now you subtract and add equal parts from it to get your other two. You subtract 153 by two and get 151. Then you add 153 by 2 and get 155.

According to the synthetic division below, which of the following statements are true? Check all that apply.
-6)2 9 -12 2 -3 11
A. When x = -6,2x2 + 9x-7 = 11.
B. When x = 6,2x2 + 9x-7 = 11.
C. (x-6) is a factor of 2x + 9x- 7.
D. When (2x + 9x-7) is divided by (x - 6), the remainder is 11.
E. When (2x2 + 9x - 7) is divided by (x + 6), the remainder is 11. F. (x+6) is a factor of 2x2 + 9x-7.
The last number on a synthetic division represents the remainder of the division.
The true statements are:
(a). When x = -6, 2x^2 + 9x - 7 = 11. (e). When (2x2 + 9x - 7) is divided by (x + 6), the remainder is 11.From the question, we have the dividend to b 2x^2 + 9x - 7, the last number to be 11, and the zero of the divisor to be -6.
This means that:
[tex]x = -6[/tex] --- the divisor
Set to 0
[tex]x+6 = 0[/tex]
So, when the dividend 2x^2 + 9x - 7 is divided by divisor x + 6, the remainder is 11.
This also means that, when -6 is substituted for x in the dividend, the remainder is 11
Hence, the true statements are (a) and (e)

Answer:
-1/2
Step-by-step explanation:
1. The formula to find the slope given two points is [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]. Now, all we have to do is plug in the values.
2. (Solving)
[tex]\frac{(-6)-(-5)}{(-1)-(-3)}[/tex] [tex]\frac{-6+5}{-1+3}[/tex] [tex]\frac{-1}{2}[/tex] [tex]-\frac{1}{2}[/tex]Therefore, the slope is -1/2.
Answer:
B. - 1/2Step-by-step explanation:
Use slope formula and substitute given coordinates:
[tex]m=(y_2-y_1)/(x_2-x_1)[/tex][tex]m =(-6-(-5))/(-1-(-3))=-1/2[/tex]sketch the graph of the equation 3y+4x=2
Simplifying
3y + 4x = 2
Reorder the terms:
4x + 3y = 2
Solving
4x + 3y = 2
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-3y' to each side of the equation.
4x + 3y + -3y = 2 + -3y
Combine like terms: 3y + -3y = 0
4x + 0 = 2 + -3y
4x = 2 + -3y
Divide each side by '4'.
x = 0.5 + -0.75y
Simplifying
x = 0.5 + -0.75y
The line connecting two coordinates (0,66) and (0.5,0) show below.
What is Mathematical equation ?
By definition, an equation is a mathematical statement made up of two expressions linked by an equal sign. In other words the equation represents the graph between x and y that is for each value of x there exist one value of y.
Here, the given equation is :
3y + 4x = 2
now, to sketch the equation in graph we need to find the two coordinate first,
Let, x= 0 then y will be :
3y+4x=2
3y = 2
y = 2/3 = 0.66
that is first coordinate is (0,66)
Now, for y = 0 , x will be :
3y+4x=2
4x = 2
x = 0.5
that is second coordinate will be (0.5 , 0)
Now, draw the line connecting these two points show below.
