Riley's math teacher said that each question answered correctly on a test would be worth 3 points. Answer the questions below regarding the relationship between the number of questions correct and the score on the test.
The independent variable, x, represents the number of questions Riley answered correctly, and the dependent variable is the score, because the score depends on the number of questions Riley answered correctly. A function relating these variables is R(x) = [3x] So R(23) = [69], meaning 23 correct answers will give a score of 69.
The types of variables.In an experiment, there are two (2) main types of variables and these include:
Dependent variable.Independent variable.What is an independent variable?An independent variable can be defined as the variable that is being manipulated by an experimenter or researcher. This ultimately implies that, it is typically considered to be the cause in an experiment and represented by x.
In this scenario, we can infer and logically deduce that the independent variable, x, represents the number of questions Riley answered correctly, and the dependent variable is the score, because the score depends on the number of questions Riley answered correctly. A function relating these variables is R(x) = [3x] So R(23) = [69], meaning 23 correct answers will give a score of 69.

Solve the system of equations –2 + y = 14 and -5x – 7y = 10 by
combining the equations.
Answer:
[tex](x,y)=(-\frac{122}{5}, 16)[/tex]
Step-by-step explanation:
Substitute the value of y
[tex]\left\{{{y=16} \atop {-5x-7y=10}}\right.[/tex]
Solve the equation
[tex]-5x-7*16=10[/tex]
A possible solution is
[tex]x=-\frac{122}{5}[/tex]
Check the solution
[tex](x, y) = (-\frac{122}{5}, 16)\\[/tex]
Simplify
[tex]\left \{ {{-2+16=14} \atop {-5*(-\frac{122}{5})-7*16=10}} \right.[/tex]
The ordered pair is a solution
[tex]\left \{ {{14=14} \atop {10=10}} \right.[/tex]
A bakery sells six cookies for every one cake. Yesterday the store
sold 154 cookies and cakes combined. How many cakes were sold?
Answer:
22 cakes were sold.
Step-by-step explanation:
In order to solve this, add the cookies and cakes together (6+1=7) to get 7. Next, divide the cookies and cakes sold combined and divide that by the 7. 154/7=22. You sold 22 cakes and 132 cookies.
To check this answer multiply 6*22=132. Then multiply 22*1=22.
And add; 132+22=154.
Hope this helps!

An electrician charges $40 to come to your house. She also charges $55 for each hour that she works. The electrician charges you a total of $205. How many hours does the electrician work at your house? Use h for the number of hours.
Answer:
$40 + h = $190
190 - 40 = 150
150 ÷ 55 ≈ 2.70 = 3
SO the electrician worked about 3 hours at your house.
h ≈ 3

What is this? I don’t know the answers plz help
Answer:
C
Step-by-step explanation:
Answer:
c.
Step-by-step explanation:
Starting with the multiplications, first the multiply matrix A by -4, so we multiply every value in the matrix by -4 and we get
16 16 -4
-4 -16 -28
-8 -12 -12
Then we do the next multiplication which is 8 by matrix B, so once again we multiply every value in the B matrix by 8
16 72 -72
64 64 -16
32 80 8
Now that we did both multiplications, just need to sum the results, so we sum each value of matrix A with the value on the matrix B that's on the same spot
16 + 16 16 + 72 -4 + (-72)
-4 + 64 -16 + 64 -28 + (-16)
-8 + 32 -12 + 80 -12 + 8
And the final result is
32 88 -76
60 48 -44
24 68 -4
So it's option c

Problem Situation: Donelle is selling bread for $3 per loaf.
He also sells one specialty cake for $36.
He makes a total of $117.
How many loaves of bread does he sell?
Select the equation that represents this situation.
The letter b represents the number of loaves of bread Donelle sells.
Answer:
36 + 3b = 117
Step-by-step explanation:
36 is the one specialized cake he sold.
3 is the cost and b is how many it represents
117 is your total, so we piece it together.
36 + 3(b) = 117
Answer:
36 + 3b = 117
Step-by-step explanation:
36 is the one specialized cake he sold.
3 is the cost and b is how many it represents
117 is your total, so we piece it together.
36 + 3(b) = 117

Write the equation of the line parallel to y=1/3x-6 that passes through the point (-12,3) in slope-intercept form.
Answer:
y=1/3x+7
Step-by-step explanation:
1. The given equation is y=1/3x-6 and it has to be parallel passing through (-12,3), so you just plug in the x and y values into the equation y=mx+b with 1/3 as the slope since its parallel (meaning the slope is the same for both eqts)
2. 3=1/3(-12)+b
3. 3=-4+b
4. 7=b
5. So, the equation is y=1/3x+7

Given 1000x = 1000, what is x?
Answer:
x = 1
Step-by-step explanation:
Given
1000x = 1000 ( divide both sides by 1000 )
x = [tex]\frac{1000}{1000}[/tex] = 1
The given equation is,
→ 1000x = 1000
Let's find the required value of x,
→ 1000x = 1000
→ x = 1000/1000
→ [x = 1]
Therefore, 1 is the value of x.
Evaluate the function.

Answer:
5)7:8=180
84:96=180
6)4:5=90
40:50=90
7)a). q=135
p=45
b).a=70
b=110
supplementary angle=sum of two angle 180°
complementary angle=sum of two angle 90°
Answer:
5) Ans;The two angle 7 and 8 —> 7x and 8x
Sum of two supplementary angle is 180°
7x +8x =180
15x =180
x= 180/15
x = 12°
7x =7(12)= 84°
8x = 8(12)= 96°
The angles; 84° , 96°
6) Ans;The two angle 4 , 5 —> 4x and 5x
Sum of two complimentary angle is 90°
4x+5x =90
9x =90
x=90/9
x=10
4x—> 4(10) = 40°
5x —> 5(10) = 50°
The angles; 40° , 50°
7) Ans;q= 135 ( Vertically Opposite angles)
q+p = 180
135+p=180
p=180-135
p = 45°
_______o_____o_____
a= 70° ( Alternate angles)
a+ b = 180
70 + b = 180
b =180 - 70
b = 110
So ; angle a=70° , b = 110°
