Answer:

5/3

2. -3

3. 2/3

Step-by-step explanation:

Slope = rise / run

If we start from where the line crosses the y axis (at y = 5) we count down 5 units till we get to the 0 . Then we count 3 to the left from there (to where the line crosses the axis) we have

5 / 3 = required slope.

2. slope = -3/1 = -3

3. slope = 2/3

Answer:

You can solve this two ways:

Part 1: If you are doing slope, your answer would be 5/3 from point (0, -3) to point (0, 5) by going 5 units up and 3 units over.

Part 2: You can find it by using the formula (y2 - y1)/(x2 - x1).

(y2 - y1)/(x2 - x1)

(5 - 0)/(0 - 3) = 5/3

You will still get the exact same answer no matter which way you do it.

Hope this helps you! :)

Use the following regression results to answer the remaining questions. Y measures average hourly earnings AHE in U.S. dollars f

Ulleksa [173]

Answer:

Check the explanation

Step-by-step explanation:

Y = 11.5 + 4.5*X1 -2.5*X2 +0.7*X3+1.6*X4 -2.4*X5 -2.8*X6

FOR JANE

X1 =1 , X2 =1 , X3 =5 , X4 =0 ,X5=0, X6=1

SO,

Y =11.5+(4.5*1)-(2.5*1)+(0.7*5)+0+0-(2.8*1)

= 14.2

..........................

FOR Sophie

X1 =1 , X2 =1 , X3 =10 , X4 =1 ,X5=0, X6=0

so,

Y =11.5+(4.5*1)-(2.5*1)+(0.7*10)+ (1.6*1)+0+0

= 22.1

please help: What is the equation of a line parallel to -5x + y= 2 that passes through the point with coordinates (-2, 1)?

weqwewe [10]

Answer:

y = 5x + 11 or -5x + y = 11

Step-by-step explanation:

Given line:

-5x + y = 2

In slope-intercept form:

y = 5x + 2

The parallel line has the same slope and will look as:

y = 5x + b

This line passes through the point (-2, 1), substitute:

1 = 5*(-2) + b
b = 1 + 10
b = 11

So the line is:

y = 5x + 11

-5x + y = 11

Which of these four sets of side lengths will form a right triangle? Set 1 4 cm, 5 cm, 6 cm Set 2 8 in., 12 in., 20 in. Set 3 10

Alenkasestr [34]

Answer: The correct option is (D) SET 4.

Step-by-step explanation: We are to select the correct set of side lengths that will form a right-angled triangle.

To form a right-angled triangle, we must have the following relation:

Perpendicular² + Base² = Hypotenuse².

Hypotenuse is the length of the largest side; perpendicular and base are the two legs of the triangle.

SET 1 : 14 cm, 5 cm, 6 cm.

We have

$5^2+6^2=25+36=61,\\\\14^2=196.$

Therefore,

Perpendicular² + Base² ≠ Hypotenuse².

So, this set will not form a right-angled triangle.

SET 2 : 8 in., 12 in., 20 in.

We have

$8^2+12^2=64+144=208,\\\\20^2=400.$

Therefore,

Perpendicular² + Base² ≠ Hypotenuse².

So, this set will not form a right-angled triangle.

SET 3 : 10 mm, 20 mm, 30 mm.

We have

$10^2+20^2=100+400=500,\\\\30^2=900.$

Therefore,

Perpendicular² + Base² ≠ Hypotenuse².

So, this set will not form a right-angled triangle.

SET 4 : 12 ft, 16 ft, 20 ft.

We have

$12^2+16^2=144+256=400,\\\\20^2=400.$

Therefore,

Perpendicular² + Base² = Hypotenuse².

So, this set will form a right-angled triangle.

Thus, the SET 4 will form a right-angles triangle.

Option (D) is correct.
