Answer:
$12 per hour
Step-by-step explanation:
In order to find her hourly rate we have to find the amount of dollars billed per hour. To do this we can use this expression: [tex]\frac{y2 - y1}{x2 - x1}[/tex]
Let's use the points (1, 27) and (2, 39) in the expression:
[tex]\frac{39 - 27}{2 -1}[/tex]
Now let's simplify the expression:
39 - 27 = 12
2 - 1 = 1
The expression simplifies to 12/1, or 12. This means that Brenda is billed $12 every hour she uses her phone.
I hope this helps :)

Solve the system of equations.
\begin{aligned} &-6y+11x = -36 \\\\ &-4y+7x=-24 \end{aligned}
−6y+11x=−36
−4y+7x=−24
Answer:
The solutions to the system of equations will be:
[tex]y=6,\:x=0[/tex]
Step-by-step explanation:
Given the equation
[tex]-6y+11x=-36[/tex]
[tex]-4y+7x=-24[/tex]
solving the system of equations
[tex]\begin{bmatrix}-6y+11x=-36\\ -4y+7x=-24\end{bmatrix}[/tex]
[tex]\mathrm{Multiply\:}-6y+11x=-36\mathrm{\:by\:}2\:\mathrm{:}\:\quad \:-12y+22x=-72[/tex]
[tex]\mathrm{Multiply\:}-4y+7x=-24\mathrm{\:by\:}3\:\mathrm{:}\:\quad \:-12y+21x=-72[/tex]
[tex]\begin{bmatrix}-12y+22x=-72\\ -12y+21x=-72\end{bmatrix}[/tex]
[tex]-12y+21x=-72[/tex]
[tex]-[/tex]
[tex]\underline{-12y+22x=-72}[/tex]
[tex]-x=0[/tex]
[tex]\begin{bmatrix}-12y+22x=-72\\ -x=0\end{bmatrix}[/tex]
solving for x
[tex]-x=0[/tex]
[tex]\mathrm{Divide\:both\:sides\:by\:}-1[/tex]
[tex]\frac{-x}{-1}=\frac{0}{-1}[/tex]
[tex]x=0[/tex]
[tex]\mathrm{For\:}-12y+22x=-72\mathrm{\:plug\:in\:}x=0[/tex]
[tex]-12y+22\cdot \:0=-72[/tex]
[tex]-12y+0=-72[/tex]
[tex]-12y=-72[/tex]
[tex]\mathrm{Divide\:both\:sides\:by\:}-12[/tex]
[tex]\frac{-12y}{-12}=\frac{-72}{-12}[/tex]
[tex]y=6[/tex]
Therefore, the solutions to the system of equations will be:
[tex]y=6,\:x=0[/tex]
Solve the system
x + 3y = 6
2x + 4y = 12

Answer:
y=.1x+3 I think that is the answer
Answer:
y=0.1x+3
Step-by-step explanation:
The slope is 0.1, (Y2-Y1/X2-X1) --> (2.5-3)/(-5-0)= -0.5/-5=0.1
The y-intercept is 3
y=0.1x+3

Answer:
a) x = 5b) x = 4Step-by-step explanation:
a)
4x - 3 = 2x + 7
4x - 2x = 7 + 3
2x = 10
x = 10 / 2
x = 5
b)
2x + 6 = 7x - 14
6 + 14 = 7x - 2x
20 = 5x
x = 20 / 5
x = 4
Which is the best estimate of 11 and one-fifth divided by 2 and three-fourths?
Answer:
4 should be the answer to the question
Answer:
11 1/5 divided by 2 3/4:
11 1/5 is a bit less than 12, and 2 3/4 is a bit less than 3
The answer, therefore, should be fairly close to 12 ÷ 3

The scale factor of the blueprint of a front door to the actual front door is 0.04. The area of the actual front door is 36 ft2 .
What is the area of the front door on the blueprint?
0.0576 ft2
0.04 ft2
0.576 ft2
1.44 ft2
Answer:
0.0576 ft2
Step-by-step explanation:
If the scale factor between a front door's blueprint and the actual front door is 0,04 The front door's actual area is 36 ft2, while its area on the blueprint will be 1.44 ft².
What is a scale factor?The ratio among comparable dimensions of an object and a model with that object is known as an exponent in algebra. The replica will be larger if the scale factor is a whole number. The duplicate will be lowered if the step size is a fraction.
It is given that, the scale factor of the blueprint of a front door to the actual front door is 0.04. The area of the actual front door is 36 ft².
Scale factor =Area of the new shape ÷ Area of the original shape
0.04= Area of the front door on the blueprint÷36 ft²
Area of the front door on the blueprint=0.04×36
Area of the front door on the blueprint=1.44 ft²
Thus, if the scale factor between a front door's blueprint and the actual front door is 0,04 The front door's actual area is 36 ft2, while its area on the blueprint will be 1.44 ft².
