Answer:

  B.  y = 1.5x +8

Step-by-step explanation:

You can try x=4 in the various equations to see which gives the right value (14).

__

A: y = -8(4) +1.5 = -30.5

B: y = 1.5(4) +8 = 14 . . . . . . . . .  this equation works

C: y = 8(4) +1.5 = 33.5

D: y = -1.5(4) +8 = 2

__

Alternatively, you can use the 2-point form of the equation of a line to write the equation:

  y = (y2 -y1)/(x2 -x1)(x -x1) +y1

  y = (20 -14)/(8 -4)(x -4) +14 . . . . fill in (x1, y1) = (4, 14); (x2, y2) = (8, 20)

  y = 1.5(x -4) +14 . . . . . simplify somewhat

  y = 1.5x +8 . . . . . . . . write in slope-intercept form

I can give you the equations for the graph. First one would be y = 0.90x + 25 (25 being the y intercept) and the other one would simply be y = 1.35. If you have a graphing calculator like me you can use it when modeling the graph. Hopefully this helps!

Find the product.
4vir4ik [10]
Answer :

6{y}^{4} {z}^{2} + 12 {y}^{3} {z}^{2}-3 {y}^{3} {z}+3 {y}^{2} {z}^{2}

Step-by-step explanation :

To find the product of

3 {y}^{2} z(2 {y}^{2} z + 4yz - y + z)

First we expand the bracket ,

it implies that, we use the expression outside the bracket to multiply individual expressions inside the bracket.

Hence

3 {y}^{2} z(2 {y}^{2} z + 4yz - y + z)

= 3 {y}^{2} z(2 {y}^{2} z) + 3 {y}^{2} z(4yz) - 3 {y}^{2} z(y )+3 {y}^{2} z( z)

we now apply the law of indices

{a}^{m} \times {a}^{n} = {a}^{m+n}

meaning, when you are multiplying two expressions with the same bases , repeat one of the bases and add the exponents.

Then, simplify to obtain

= 6{y}^{4} {z}^{2} + 12 {y}^{3} {z}^{2}-3{y}^{3} {z}+3 {y}^{2} {z}^{2}

Martin and Alexia are rock climbing each person's rate stays the same for the first hour they climb mountain climbers 3 1/3 mete
Minchanka [31]

1. If Martin climbs 3 1/3 meters in the first one 1/6 hour, then he climbs

3\dfrac{1}{3}\cdot 6=\dfrac{10}{3}\cdot 6=20 meters per hour. Then, option A is correct and options C and E are false.

2. If Alexia climbs 17 1/2 in the first 5/6 hour, then she climbs

17\dfrac{1}{2}\cdot \dfrac{6}{5}=\dfrac{35}{2}\cdot \dfrac{6}{5}=21 meters per hour and it takes Alexia \dfrac{1}{21} of an hour to climb 1 meter. Then options B and D are correct and option F is false.

Answer: correct options are A, B and D.

The length of a banquet table is 4 feet longer than 6 times its width. If the perimeter is 78 feet, what are the dimensions of t
harina [27]
Hello,
2(l+w)=78
Divided 2 from both side
2(l+w)/2=78/2
l+w=39 feet

l=6w+4
Replace l with 6w+4

6w+4+w=39
7w+4=39
Subtract 4 from both side
7w=35
Divided 7 from both side
w=5 feet
l=6w+4
l=6(5)+4
l=30+4
l=34 feet. As a result, the length of the rectangle is 34 feet and the width of rectangle is 5 feet. Hope it help!
