Which expression is equivalent to : - 2/7 (-14y + 42)
Answer: 4y -12
Step-by-step explanation:
Let's take this step-by-step:
[tex]-\frac{2}{7}[/tex](-14y + 42)
Distribute the [tex]-\frac{2}{7}[/tex] to -14y and 42
[tex]-\frac{2}{7}[/tex] * -14y = 4y
[tex]-\frac{2}{7}[/tex] * 42 = -12
We get
4y + (-12)
Simplify this to get:
4y -12

Answer:
(D)The first column is labeled x with entries 40, 160, 200. The second column is labeled y with entries 60, 15, 0.
Step-by-step explanation:
The piece-wise function, f(x) is defined as follows:
[tex]f(x)=\left\{\begin{array}{ccc}-\frac{5}{4}x+90 &0\leq x<40\\\\-\frac{3}{8}x+75 &40\leq x\leq 200\end{array}\right[/tex]

Answer:
f(x)=2x
Step-by-step explanation:
You can get your (a)term by finding rise/run, and there is no y-intercept so the (b)term is not known. Thus you get f(x)=2x.
The equation of the line is [tex]y = 2 x[/tex]
From the graph, we have the following ordered pairs
(0,0) and (5,10)
The equation of the line is calculated using
[tex]y = \frac{y_2 -y_1}{x_2 -x_1} \times (x -x_1) + y_1[/tex]
So, we have:
[tex]y = \frac{10 - 0}{5 - 0} \times (x -0) + 0[/tex]
[tex]y = \frac{10}{5} \times (x -0)[/tex]
[tex]y = 2 \times x[/tex]
Evaluate the product
[tex]y = 2 x[/tex]
Hence, the equation of the line is [tex]y = 2 x[/tex]

Step-by-step explanation:
The value of r in the given parallelogram is 9 and the length of EF is 55 units.
What is a parallelogram?A parallelogram is a special type of quadrilateral that has both pairs of opposite sides parallel and equal.
Given that, in a parallelogram FCDE sides DC and FE are parallel, and sides FC and ED are parallel. The length of CD is 4r + 19, the length of DE is 8r + 3, and the length of FC is 9r - 6.
Since, we know that,
Opposite side of a parallelogram are parallel and equal, therefore,
FC = DE and DC = FE
Therefore,
8r+3 = 9r-6
r = 9
Therefore,
FE = DC = 4r+19
= 36+19
= 55
Hence, the value of r in the given parallelogram is 9 and the length of EF is 55 units.

Please answer this I need help! There are 90 people going on the field trip. The budget allows for $542.94 total for tickets to Nashville sounds game. There is a service fee of $45.82. How much does each ticket cost?
Answer:
5.52 or less
Step-by-step explanation:
The total cost must be less than or equal to the budget amount
Total cost limit ≥ fee + cost per ticket * number of tickets
542.94 ≥ 45.82 + cost per ticket * 90
Subtract 45.82 from each side
542.94 - 45.82≥ 45.82 -45.82+ cost per ticket * 90
497.12 ≥ cost per ticket * 90

A 14 inch pizza (diameter is 14) was cut in to 8 pieces. What is the angle measure of each slice? *
Answer:
The angle for each slice is 45 degrees.
Step-by-step explanation:
In order to calculate the angle of each slice, we first need to calculate the total area of the pizza, because we will use that to find the area of each slice and as a result it's angle. To calculate the area of the pizza we must use:
pizza area = pi*r²
r = d / 2 = 14 /2 = 7 inches
pizza area = pi*(7)² = 153.86 square inches
Since the pizza was divided in 8 pieces, the area of each piece is given by the area of the pizza divided by the number of slices. We have:
slice area = pizza area / 8 = 153.86 / 8 =19.2325 square inches
Each slice is a circle sector, therefore it's area is given by:
slice area = (angle*pi*r²)/360
Therefore we can solve for angle:
19.2325 = (angle*pi*7²)/360
angle*pi*49 = 6923.7
angle = 6923.7 / pi*49 = 45 degrees
The angle for each slice is 45 degrees.

Asa is supposed to floss his teeth using 18" of floss daily. He began a new roll 50' on March 17th. If he still has 2 feet of floss left after flossing on August 2nd, how many days has he forgotten to floss?
Answer:
Asa forgot to floss for 106 days.
Step-by-step explanation:
First of all, we will start by writing out the details we are given clearly.
Length of floss used per day = 18 inches
Original length of floss bought for use = 50 ft = 600 inches
Number of days between March 17th and August 2nd = 138 days
Length of floss left after August 2nd = 2 feet = 24 inches
From this, we can clearly calculate the length of floss used.
This will be original floss length - length of floss remaining = 600 - 24 = 576 inches
Length of floss used = 576 inches
If Asa used 18 inches per day, we can find the number of days he flossed by dividing the length used in total by the length used per day.
That will be 576/18 = 32 days
if Asa flossed for only 32 days, the number of days he didn't floss is 138 - 32 =106 days
Hence, Asa didn't floss for 106 days.

A square is made using four rods of equal length joined end to end.
The perimeter of this square is 72 cm. Three of these rods are now joined end to end to make an equilateral triangle.
What is the perimeter of this equilateral triangle?
will mark brainliest for correct answer!
Answer: 54 cm
Step-by-step explanation:
Hi, to answer this question we have to apply the next formula:
Perimeter of a square = side length x4
Replacing with the values given:
72 = 4 s
Solving for s (side length)
72/4=s
s = 18 cm
Since the side length of the square is the length of each rod, and all the rods have the same length, to obtain the perimeter of the triangle we have to apply:
Perimeter of an equilateral triangle: 3 side length
P = 3 (18 ) = 54 cm

A motorist travels between two towns. It usually takes 6 hours when travelling at a certain speed. He finds that if he reduces his speed by 15 km/hr his journey will take 1 hour more. Find his usual speed.
Answer:
His usual speed is 105 km/hr.
Step-by-step explanation:
Let his usually speed be s km/hr and the distance between the towns be d km. So we have the equations:
s = d/6
s - 15 = d / (6 + 1)
from the first equation:
d = 6s and from the second:
d = 7(s - 15)
Eliminating d we get:
6s = 7(s - 15)
7s - 105 = 6s
s = 105.
