Answer:

He needs to score a 19

Step-by-step explanation:

First, I found the mean of the three test scores. The mean was below 17 so I knew he needed a grade higher than the ones he already has. So I went up from 18. So my first equation was 15+18+16+19=68. then I divided by 4 which gives you a mean of 17. (Mean=average)

Answer:

[tex]\bold{-\frac{1}{3}(-12 + 2y)}[/tex]

Step-by-step explanation:

The original expression is

[tex]4 - \frac{2}{3}y[/tex]

Let us write the factored result as
[tex]-\frac{1}{3} (a + by)[/tex]

where a and b are constants to be determined

[tex]-\frac{1}{3} (a + by) = -\frac{1}{3} (a) -\frac{1}{3} (by) = -\frac{a}{3} + -\frac{by} {3}[/tex]

Matching like terms to the original equation we get

[tex]-\frac{a}{3} = 4[/tex]  

Multiplying by -3 on both sides gives

a = -12

Matching the y terms we get
[tex]-\frac{by}{3} = -\frac{2}{3}y[/tex] ==> [tex]-\frac{b}{3} = - \frac{2}{3}[/tex]  ==> b = 2

So the factored expression is

[tex]\bold{-\frac{1}{3}(-12 + 2y)}[/tex]

We can verify this if we multiply the terms inside the parentheses by [tex]-\frac{1}{3}[/tex]

[tex]-\frac{1}{3}(-12) =4[/tex]

[tex]-\frac{1}{3} (2y) = -\frac{2}{3}y[/tex]

Answer:1/36

Step-by-step explanation:

Since the first one has a 1/6 chance because it is a 6-sided dice, and the second roll has to be 1/6. Once you multiply 1/6 by 1/6 you get 1/36

Answer:

Step-by-step explanation:

Answer:

4%

Step-by-step explanation:

1) Subtract the base price from the final price. 40.56 - 39 = 1.56.

2) Divide the tax by the base price to determine the decimal version of the percentage. 1.56 / 39 = 0.04.

3) Multiply this by 100 to turn it into the normal percentage. 0.04 × 100 = 4, so the answer is 4%.

The sales tax is 38.46%.

The percentage is the ratio of number expressed as a fraction of 100.

Determine the difference in the amounts.

Difference = Amount paid - Amount listed

=40.56-39

=1.56

Determine the percent sales tax.

Percent sales tax= (Difference/ Amount paid) ×100%

=(1.56/40.56) ×100%

≈38.46%

Thus, the sales tax is 38.46%.

Answer:

D

Step-by-step explanation:

to find which ordered pair is a solution to the equation.

substitute the x- coordinate into the right side of the equation and if the value obtained is equal to the y- coordinate then the ordered pair is a solution.

A (0, 0 )

y = - 3(0) - 5 = 0 - 5 = - 5 ≠ 0 ← not a solution

B (- 1, 8 )

y = - 3(- 1) - 5 = 3 - 5 = - 2 ≠ 8 ← not a solution

C (1, - 2 )

y = - 3(1) - 5 = - 3 - 5 = - 8 ≠ - 2 ← not a solution

D (1, - 8 )

y = - 3(1) - 5 = - 3 - 5 = - 8 ← solution

then (1, - 8 ) is a solution to the equation

Answer:

D. (1, -8)

Step-by-step explanation:

Given: y = -3x - 5

Using substitution, we can substitute the given value of coordinates into the equation to see which coordinate makes a true statement.

A. (0, 0)

0 = -3(0) - 5

0 = -5

This is a false statement.

B. (-1, 8)

8 = -3(-1) - 5

8 = 3 - 5

8 = -2

This is a false statement.

C. (1, -2)

-2 = -3(1) - 5

-2 = -3 - 5

-2 = -8

This is a false statement.

D. (1, -8)

-8 = -3(1) - 5

-8 = -3 - 5

-8 = -8

This is a true statement.

Therefore, the correct answer is D.

Answer:

given, y≥2x+1 and 

y>21x−1

first, draw the graph for equations  y=2x+1 and y=21x−1

for y=2x+1 

substitute y=0 we get, 2x+1=0⟹x=−0.5

substitute x=0 we get, y=1

therefore, y=2x+1 line passes through (0.5,0) and (0,1) as shown in fig.

Hence,  y≥2x+1 includes the region above the line.

for y=21x−1

(a)

Five rational numbers between -1 and 1 are:-

:: -9/10, -8/10, -7/10, -6/10,-5/10

(b)

Five rational numbers between 4/3 and 3/2 are:-

:: 81/60, 82/60, 83/60, 84/60, 85/60

Explanation:-

If we have to find rational numbers we have to multiply both the numerator and denominator by same number

eg:- 5,10,20. In case you do not find five or ten rational numbers you have to again multiply the numerator and denominator by the same number.

Answer:

The scale factor is 5/2

Step-by-step explanation:

To find the scale factor, divide 20/8; that simplifies into 5/2.

20÷5/2 is 20*2/5, which is equal to 8, so you know it works.

Answer:

154

Step-by-step explanation:

bc z is striaght line = 180

so 180 -26 = 154

remember

y + 26 = z

Answer:

∠y = 154°

Step-by-step explanation:

- angle ∠z is a straight angle meaning it equals 180 180°

this is also known as...

supplementary angles (when two angles whose sum is 180°)

- one of the two angles are given:

angle 1: 26°

angle 2: ∠y °

26 + ∠y = 180 °

subtract 26 from both sides to get y alone

26 -26 + ∠y = 180 ° - 26

∠y = 154°

∠y is an obtuse which is confirmed by 154°

Explanation:

Reflection over the x -axis is (x,y) → (x,−y)

Here the given point:

N(-3, -4)

If reflected:

(-3, 4)

Answer: (-3, 4)

Explanation:

When you reflect a point across the x-axis, the x-coordinate remains the same, but the y-coordinate is taken to be the additive inverse. The reflection of point (x, y) across the x-axis is (x, -y).

(-3, -4) ⇒ (-3, 4)
