Solve for x and y:
Ty– 5x = 45
x = 8 - 2y
O x = 5, y = 10
O x = 5, y = -2
x = -2, y = 5
O x = 4, y = 2

Answers

Answer 1

Answer:

x = -2

y = 5

Step-by-step explanation:

7y - 5x = 45    -------------------(I)

x = 8 - 2y -----------------------(II)

Substitute x = 8 - 2y in equation (II)

7y - 5(8-2y) = 45

7y + 8 *(-5) - 2y*(-5) = 45

7y - 40 + 10y = 45

17y - 40 = 45

17y = 45 + 40

17y = 85

y = 85/17

y = 5

Plugin y = 5 in equation (II)

x = 8 - 2*5

x = 8 - 10

x = -2

What is the gradient?

Answers

Answer:

Gradient = 2

Step-by-step explanation:

Gradient of a line = Slope of the line

Since, slope of a line passing through two points [tex](x_1, y_1)[/tex] and [tex](x_2,y_2)[/tex] is given by,

Slope = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

Given line in the graph passes through two points (1, 0) and (2, 2)

Therefore, slope or gradient of the line = [tex]\frac{2-0}{2-1}[/tex]

                                                                  = 2

Gradient = 2 will be the answer.

A triangle has vertices T(-2,4), E(6,2), and D(1,-1). Is ATED a right triangle?
No, this is not a right triangle.
Yes, because ED is perpendicular to DT which makes a right angle.
Yes, because TE is perpendicular to DT which makes a right angle.
Yes, because TE is perpendicular to ED which makes a right angle.

Answers

Answer:

B. Yes, because ED is perpendicular to DT which makes a right angle.

Step-by-step explanation:

Plot the given points and connect in pairs to get a triangle.

Visually we can say it is a right triangle as legs TD and ED seem perpendicular.

Let's confirm this by finding the slopes.

Slope of TD:

m = (-1 - 4)/(1 -(-2)) = -5/3

Slope of ED:

(-1 - 2)/ (1 - 6) = -3/-5 = 3/5

Product of the slopes is:

-5/3*3/5 = -1

This confirms DT⊥ED

Correct choice is B

(A.) 0.4 pound; on average, the weight of a box varies 0.4 pounds from the mean of 2 pounds

(B.) 0.8 pound; on average, the weight of a box varies 0.8 pounds from the mean of 2 pounds

(C.) 0.4 pound; the weight of 50% of the boxes is greater than 0.4 pound

(D.) 0.8 pound; the weight of 50% of the boxes is greater than 0.8 pound

Answers

Answer:

c is the answer

Step-by-step explanation:

Answer:

Step-by-step explanation:

First put the numbers from least to greatest: 1, 2, 2, 2, 3       2 is the mean.

Then you determine the distance each data value is from the mean.

1, 2, 2, 2, 3

1, 0, 0, 0, 1

Calculate the mean of the distances:  1 + 0 + 0 + 0 + 1 = 2

Then divide:  2 divided by 5 = 0.4

So your answer is 0.4 pound; on average, the weight of a box varies 0.4 pounds from the mean of 2 pounds
