Answer:

-2.4-(-7) has the same result as -2+7 because the negative sign and the minus sign cancel each other out. Think of it like this. If you cross the negative sign and the minus sign together, then it makes a plus sign.

Step-by-step explanation:

I gave a basic answer. You might have to elaborate more on this.

The equation of the line of best fit is F=1.5h -4.3, where F is foot length in millimeters and h is height in centimeters. Expla
iogann1982 [59]

Answer:

Slope, m = 1.5

y-intercept, c = -4.3  

Step-by-step explanation:

We are given the following equation in the question:

F=1.5h -4.3

where F is foot length in millimeters and h is height in centimeters.

Comparing equation to a general linear equation:

y = mx + c

where m is the slope and c is the y - intercept.

Slope, m = 1.5

y-intercept, c = -4.3

Interpretation of slope:

Slope tells us about the rate change. So, when the there is a unit increase in height the foot length changes by 4.3 foot.

Interpretation of y-intercept:

y-intercept is the value of F when height,h is zero that is

F(0)=1.5(0) -4.3 = -4.3

What is 16 over 32 simplified
Vinvika [58]

Answer:

40° and 140° (with x = -10)

Step-by-step explanation:

Since the angles are supplementary (when added, equal 180°), you can add the two angles together to get (-18x)°. 180/-18 = -10 for x. Fill in -10 for x in both expressions. (-14 • -10)= 140° and (-4 • -10)- 40°. 140+40=180
