Answer:

y = -4x - 3

Step-by-step explanation:

y = -4x + 2

Substitue Y and X and turn 2 into b(or y intercept)

5 = -4(-2) + b

Solve for b

5 = 8 + b: subtract 8 from both sides

-3 = b

substitute for 2 with same slope(to keep parrallel)

y = -4x - 3

Answer:

15/4 z + 12

Step-by-step explanation:

B) t = 70 h

A factory produces 70 toys per hour. The relationship between the number of toys produced, t, and the number of hours elapsed, h, is proportional.

Answer: 720

24 hours x 30 days = 720 hours

24x28=672. There is 24 hour a day and there is 28 days in 4 weeks.

Answer:

g(x) = 4x + 2

Step-by-step explanation:

g(x) = f(x) + 5 = 4x - 3 + 5 = 4x + 2

Answer:

Here side(a) = 2 cm. = (√3/4) (2)². = (√3/4) x (2) x (2). = (√3). = √3 cm².

Step-by-step explanation:

A = √3 cm²

Hi there !

use formula for area of equilateral triangle

[tex]A=\frac{s^{2} \sqrt{3}}{4}[/tex]

s = side

A = (2cm)²√3/4

= 4√3cm²/4

= √3 cm²

Good luck !

Answer:

To find : If 21m, 28m and 49m form a right angle or not.

Logic : To find if this triangle is a right angle, we can use the Pythagoras Theorem, which states that the square if the longest side should be equal to the square of the sum of the other two sides.

The name of the longest side is called the hypotenuse, while the others are called legs or one is the perpendicular and the other the base.

Proof : [tex]h^{2} = p^{2} + b^{2}[/tex]

=> [tex]49^{2} = 28^{2} + 21^{2}[/tex]

=> 2401 = 784 + 441

=> 2401 ≠ 1225

Therefore these side lengths cannot be the lengths of a right angled triangle.

Answer:  option C.)   an 1.2 (n-1) -5  Sorry, no subscript for "a sub n"

Step-by-step explanation:

Substitute the values of n 1,2,3,4 and see if the output is the corresponding number in the sequence.

n = 1      2     3      4

   -5   -3.8  -2.6  -1.4

an=  1.2 (n-1) -5    the n-1 needs to be a number multiplied  by 1.2 produces a number added to -5 results in the number in the sequence.

a1=1.2(1-1) -5   a= 1.2(0) -5  a= -5

a2 1.2 (2-1) -5   a= 1.2(1) -5  a= -1.2 -5  a= -3.8

a3 1.2 (3-1) -5   a= 1.2(2) -5  a= -2.4 -5  a= -2.6

a4 1.2 (4-1) -5   a= 1.2(3) -5  a= -3.6 -5  a= -1.4

Answer:

1.) C

2.) C

3.) A

5.) B

Step by-step explanation:

1.) because 14 is positive and the opposite of 12 is -12. So 14+-12=2!

2.) to get to 7 from -7 you would have to take 7 units to get there.

3.)Given that a football player caught the ball and made a gain of 8 yards on the first play. On the next play the team lost 12 yards.we are to find the number of yards needed to gain on the next play to get back to their original position.Let, x be the number of yards that the team had originally.On the next play, the team lost 12 yards, let 'k' be the number of yards  needed to gain on the next play to get back to their original position.Thus, the number of yards needed to gain on the next play to get back to their original position is 4.

5.) We have been given that on Monday morning the temperature was 38°F, but by the afternoon the temperature had risen 22°F. We are also told that on Tuesday morning the temperature had dropped 27°F since Monday afternoon.Since the temperature rose  by the Tuesday noon, so temperature by Tuesday noon will be 10 degrees greater than temperature by Tuesday morning.To find the number of degrees temperature is above or below 38°F on Tuesday at noon we will subtract 38°F from the temperature on Tuesday at noon. Since the difference between temperature is positive, therefore, the temperature on Tuesday at noon was 5 above .

Answer:

The difference in cost per mile is $0.94.

Step-by-step explanation:

Uber

7x = 20.37

x = $2.91 per mile

Lyft

4y = 15.4

y = $3.85 per mile

3.85 - 2.91 = 0.94

Hello.

To find the difference in cost per mile, divide the cost by the amount of miles, then subtract the two answers.

20.37 / 7 = 2.91 (cost per mile {cpm} for Uber)

15.40 / 4 = 3.85 (cost per mile {cpm} for Lyft)

3.85 - 2.91 = 0.94

The difference in cost per mile is $0.94
