Step-by-step explanation:

[tex]y = 6x - 2[/tex]

[tex]y_1 = 6(-5) - 2 = -30 -2 = -32[/tex]

[tex]y_2 = 6(-1) - 2 = -6 -2 =-8[/tex]

[tex]y_3 = 6(0) - 2 = 0 -2 = -2[/tex]

[tex]y_4 = 6(1) - 2 = 6 -2 = 4[/tex]

Step-by-step explanation:

Ok so the function rule is: y=6x-2

We have 4 sets of numbers under the value "x." That means we have to input the given values into the function.

First is x=-5. We input -5 into the function so we get y=6(-5)-2. We multiply 6 and -5 and we get -30, then we subtract 2 from -30. Then for the answer for the first column, we get -32 for the y value.

Now we have x=-1. We input the number for x in the function and we get y=6(-1)-2. We multiply 6 and -1 and we get -6, then we subtract -2 from -6 and we get -8. So out y value for the second row is -8.

need help multie choice​

Answers

the answer is a the same line

Answer:

A - The same line

Step-by-step explanation:

First, let's simplify 6x - 15y = 15:

Add 15y to both sides to get 15 + 15y = 6x, and then subtract 15 on both sides to get 15y = 6x - 15. We can then divide by 15 on both sides to get y = 6x/15 - 1, which can be simplified to (since 6/15 = 2/5):

y = 2x/5 - 1

y = 2x/5 - 1 is the same as the second bullet point, and since the equations of the lines are the same, this means that the lines are the same. Therefore, the answer is A - The same line.

The rectangle and the trapezoid have the same area. What is the length l of the rectangle?
Please show work

Answers

Answer:

length = 18 ft

Step-by-step explanation:

A(rect) = 9l

A(trap) = 1/2(9)(24+12)  →  4.5(36)  → 162

9l = 162

l = 162/9

l = 18

Answer:  18 feet

=====================================================

How to get the answer:

We first need to compute the area of the trapezoid

area of trapezoid = height*(base1+base2)/2

A = h*(b1+b2)/2

A = 9*(12+24)/2

A = 9*(36/2)

A = 9*18

A = 162

The trapezoid has an area of 162 square feet.

---------

The rectangle also has an area of 162 sq ft.

area of rectangle = length*width

A = L*W

A/W = L

L = A/W

L = 162/9

L = 18

The length of the rectangle is 18 feet.

---------

Side note: both rectangle and trapezoid have the same height (9 feet). Notice how the average of the 12 ft and 24 ft sides leads to 18 ft, which is exactly the value of L. It's not a coincidence these two facts line up.

Answers

Answer:
1. 1/50, or 1 megabyte per 50 seconds
2. -5/2, or -5 dollars per 2 months

Explanation:
To find slope, we can use the slope formula:
m = (y2 - y1)/(x2 - x1)

M represents the slope, (x1, y1) represent the coordinates of a point on the line, and (x2, y2) represent the coordinates of another point on the line. The points you pick don’t matter as long as they’re different.

For the first graph, I’ll pick (150, 3) and (100, 2).
m = (2 - 3)/(100 - 150)
m = -1/-50
m = 1/50

From the x and y axis, I can determine the units: megabytes per seconds. The answer becomes 1 megabyte per 50 seconds.

The second graph will have the same process. Since the line is pointing downward, I already know that the slope will be negative. I can plug the pre-chosen points, (10, 5) and (4, 20), into the slope formula.
m = (20 - 5)/(4 - 10)
m = 15/-6 or -5/2

The answer becomes -5 dollars per 2 months.

I hope this was helpful!

A factory manufactures cars and motorcycles in the ratio 8 : 12. If they make 1210 cars and motorcycles in a given period, how many cars do they make in the same period ?​

Answers

Answer:

484 cars

Step-by-step explanation:

sum the parts of the ratio, 8 + 12 = 20 parts

Divide the total made by 20 to find the value of one part of the ratio

1210 ÷ 20 = 60.5 ← value of 1 part of the ratio , then

number of cars = 8 × 60.5 = 484
