1) Which graph shows different numbers of tickets that Elena can sell to raise more than $180?
2) I would like to know who to mark people the brainiest!!! :)

Answer:

x = 4

Step-by-step explanation:

3(4x - 7) = 27

distribute the 3

(3 * 4x) + (3 * -7) = 27

12x + (3 * -7) = 27

12x - 21 = 27

add 21 to both sides of the equations

12x - 21 + 21 = 27 + 21

12x = 27 + 21

12x = 48

divide both sides by 12

12x/12 = 48/12

x = 48/12

x = 4/1

x = 4

Answer:

Length = 3 7/8cm

Width  = 2 3/4 cm

Step-by-step explanation

Let the length of the rectangle by L

Let the width be W

If the length of a rectangle is 1 1/8 cm longer than the width, then;

L = W + 1 1/8

L = W +9/8

perimeter of the  rectangle = 2(L+W)

perimeter of the  rectangle = 2(W + 9/8 + W)

13 1/4 = 2(2W + 9/8)

53/4 = 4W + 9/4

4W = 53/4 - 9/4

4W = 44/4

4W = 11

W = 11/4

Hence the width of the rectangle is 11/4 or 2 3/4 cm

Recall that L = W + 9/8

L = 11/4 + 9/8

L = (2(11) + 9)/8

L = 31/8

L = 3 7/8cm

hence the length is 3 7/8 cm

Answer:

Length = 3 7/8cm

Width  = 2 3/4 cm

Answer:

The correct option is B.

Step-by-step explanation:

Consider the provided information.

The dimensions of bricks are in inches so convert foot into inches.

1 foot = 12 in

4 feet = 48 in

8 feet = 96 in

To calculate the number of bricks that fit into space we divide the space's volume by the volume of 1 brick.

[tex]\text{Number of bricks in space}=\dfrac{12\times 48 \times96}{3\times 4 \times8}[/tex]

[tex]\text{Number of bricks in space}=576[/tex]

Hence, 576 bricks can be fit into a space.

Therefore the correct option is B.

Answer:

9+11i

Step-by-step explanation:

Step-by-step explanation:

We have logb(8) = 3 and logb(0.5) = -1.

=> b³ = 8 and 1/b = 0.5

=> b = 2.

Therefore,

logb(4b) = log2(8) = 3.

Answer:

We have, logb(8)=3 and logb(0.5)=-1

→b³=8 and 1/b=0.5

→b=2

Therefore,

logb(4b) = log2(8)=3.

Answer:

c=15+25x

Step-by-step explanation:

From the information given, you can say that the total amount Tom's Landscaping charges for a job would be equal to the flat fee plus the result of multiplying the charge per hour for the number of hours and this would be:

c=y+25x (1), where:

c is the total cost

y is the flat fee

x is the number of hours

Now, as you know that Tom charged a customer $90 for a job that required 3 hours, you can replace c with 90 and x with 3 and solve for y to find the flat fee:

90=y+25(3)

90=y+75

90-75=y

y=15

Finally, as you know that the flat fee is 15, you can replace this value in (1) to establish the equation that would calculate the total amount that Tom's Landscaping charges for a job that requires x hours of work:

c=15+25x

Answer:

Each bag of chip costs 0.99 (99 cents)

Step-by-step explanation:

Soda = 1.75

Bag of chips = x

1.75 + 3x = 4.72

Subtract 1.75 from both sides;

3x = 2.97

Divide both sides by 3;

x = 0.99

Answer:

The end behavior of a polynomial function is the behavior of the graph of f(x) as x approaches positive infinity or negative infinity. The degree and the leading coefficient of a polynomial function determine the end behavior of the graph.

Step-by-step explanation:

The expression (6.4 × 10³) ÷ (3.2 × 10²) can be simplified to 0.2 × 10² in scientific notation.

Scientific Notation is a way of writing down in the easy form of very large or very small numbers.

To evaluate this expression, you can first divide the numerator by the denominator:

(6.4 × 10³) ÷ (3.2 × 10²) = (6.4 / 3.2) × (10³ / 10²)

Next, you can simplify the fraction in the numerator:

(6.4 / 3.2) × (10³ / 10²) = 2 × (10³ / 10²)

Finally, you can simplify the fraction in the exponent:

2 × (10³ / 10²) = 2 × 10¹

2 × 10 = 20 = 0.2 × 10²

Therefore, in scientific notation, the expression (6.4 × 10³) ÷ (3.2 × 10²)  can be written as 0.2 × 10².

B'(-2,-6)

Step-by-step explanation:

Hope this helps!!

The co-ordinates of B' after a reflection across the line y = -1 are (-2,-6)

A pair of numbers that use the horizontal and vertical separations from the two reference axes to define the location of a point on a coordinate plane. A coordinate curve is created in two dimensions when one of the coordinates in a point coordinate system is kept constant while the other coordinate is permitted to change.

The coordinate curves may be referred to as coordinate lines if they are actually straight lines. The coordinate axes of Cartesian coordinate systems are lines that are orthogonal to one another. The coordinate curves may be universal curves for different coordinate systems. Curvilinear coordinate systems are those in which some coordinate curves are not lines.

x -co-ordinate of B' = -2

y-co-ordinate of B' = -6

The co-ordinates of B' after a reflection across the line y = -1 are (-2,-6)

Answer:

x = (3 + 8y) / (y - 1)

Step-by-step explanation:

y = (x + 3) / (x - 8)

Make x the subject

y = (x + 3) / (x - 8)

Cross product

y * (x - 8) = (x + 3)

xy - 8y = x + 3

xy - x = 3 + 8y

Factorize the left hand side of the equation

x( y - 1) = 3 + 8y

Divide both sides by (y - 1)

x = (3 + 8y) / (y - 1)
