Answer:

T = 88 -(7/2000)A

Step-by-step explanation:

The table values have a constant difference of +2000 ft and -7 degrees, so the slope of the linear equation is -7/2000 degrees per ft. The temperature is 88 at an altitude of 0, so we can write the requested equation in slope-intercept form as ...

T = 88 -(7/2000)A

_____

The slope-intercept form of the equation for a line is ...

y = mx + b

where m is the slope and b is the y-intercept. In this equation, y is the dependent variable and x is the independent variable. For our temperature equation, the dependent variable is T, and the independent variable is A.

56 = −8d + 8 there's not multiple answers

ollegr [7]

Answer:

d= -6

Step-by-step explanation:

56 = -8d + 8

1) You want to get d by itself. Subtract 8 from both sides.

56 = -8d + 8

- 8 - 8

(8 - 8 = 0, and 56 - 8 is 48.)

48 = -8d

2) Then, you divide my -8 on both sides.

(48 / -8 is -6, and -8d / -8 is just d.)

-6 = d

So, d = -6

HELP! NEED DONE IN 24 MIN.

Gala2k [10]

Answer:

37.8

Step-by-step explanation:

Set up a proportion using the values given in the diagram of similar triangles.

31.5/15 = x/18

Cross-multiply.

31.5(18) = 15x

Multiply.

567 = 15x

Divide both sides by 15.

37.8 = x

Bond [772]

Please see the attached image for a visual representation of our scale factor. We can set up this proportion by taking the DVD cover and poster values and placing them in fractions. Cross multiply and divide to solve for x.
