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:

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%.

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).

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

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:

[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:

240/990 = 8/33.

Step-by-step explanation:

Arbitrarily, the chances of this outcome, by picking an apple first, then an orange, then a banana, is:

5/11 × 4/10 × 2/9= 40/990

But we don't care about the order and in reality, there are six orders that would achieve our outcome:

Apple, orange, banana

Apple, banana, orange

Orange, Apple, banana

Orange, banana, Apple

Banana, Apple, orange

Banana, orange, Apple

The probability of each these outcomes is the same as computed above (Just exchanging numerators.) So the answer is 6×(40/990)
