The answer is X=1.5.
3.5(2.5+x)=14
8.75+3.5x=14
8.75+3.5x=14
3.5x=5.25
X=1.5

Answer: so first you want to do 3.5 x the 2.5 and you get 8.75, then do 3.5 x X and you get 3.5x. now the equation is 8.75 +3.5x=14. take 8.75 nnd subtract it from itself and 14 then you are left with 3.5x=5.25. divide 5.25 by 3.5x and you get 1.5. so the answer is x=1.5

Write the equation of the line through (0, −2) and (3, 13) in point-slope form. The line through (0, −2) and (3, 13) in point-sl
Strike441 [17]

Answer:

  • y + 2 = 5x

Step-by-step explanation:

<u>Point-slope form: </u>

  • <em>y - y1 = m(x - x1)</em>

<u>Slope formula:</u>

  • <em>m = (y2 - y1)/(x2 - x1)</em>

<u>Given points:</u>

  • (0, -2) and (3, 13)

<u>Finding the slope:</u>

  • m = (13 - (-2))/(3 - 0)
  • m = 15/3
  • m = 5

<u>Using point 1</u>

  • y - (-2) = 5(x - 0)
  • y + 2 = 5x

6) The scatter plot below shows the temperatures (y), in degrees Fahrenheit (°F), that were recorded at different altitudes (x),
prohojiy [21]

Answer:

y = − (7 /2) x + 60 equation could represent the line of best fit for the temperatures, in degrees Fahrenheit, based on the altitudes, in thousands of feet

Step-by-step explanation:

Given:

A plot for temperature and altitude

(Refer the attachment)  .......FOR GRAPH

To Find:

Correct relationship between them

Solution:

By using  given relationship as we can conclude.

1)y=-5x+70:

Put y=0 then

5x=70

x=70/5

x=14

This value dont corresponds when y=0 in graph

2) y=-10x+70

put y=0 then

10x=70

x=7

This value dont corresponds when y=0 in graph very less than original value.

3)y=-(7/2)x+60

put y=0 then

(7/2)x=60

7x=120

x=120/7

x=17.14

This value  corresponds when y=0 in graph

4)y=-(9/2)x+60

Put y=0 then

(9/2)x=60

9x=120

x=120/9

x=13.33

This value dont corresponds when y=0 in graph which much less than original value.

Which of the following expressions is equal to 2x2 + 18 ?
ehidna [41]
<h3>Answer: Choice C. (2x - 6i)(x + 3i)</h3>

Work Shown:

2x^2 + 18

2(x^2 + 9)

2(x - 3i)(x + 3i) .... see note below

(2x - 6i)(x + 3i)

Note: I used the rule that a^2 + b^2 = (a - bi)(a + bi). I recommend FOILing out the right hand side to confirm the equation is true. You'll use the idea that i^2 = -1.
