Answer:6.5

Step-by-step explanation: If you simplify (3 x 2) into 6, it will leave 6+6x=45. So if you subtract 6 on both sides it will cancel out the one on the left and make 45 into 39. So now you have 6x=39 so now you just divide 6 on both sides and get 6.5.

Find the slope of a line that contains the two points (-2,8) and (1,2)

kifflom [539]

Answer:

$m = -2$

Step-by-step explanation:

Slope Formula: $m=\frac{y_{2}-y_{1} }{x_{2}-x_{1}}$

Points: (-2, 8), (1, 2)

$m = \frac{8-2}{-2-1}$

$m = -2$

A family has traveled 114 miles of a planned trip. This is 37% of the total distance they must travel on the trip. Find, correct

denis23 [38]

Answer:

The total distance they will travel on their trip is 308 miles.

Step-by-step explanation:

This question can be solved using a rule of three.

114 miles is 37% = 0.37. How many mines are 100% = 1?

114 miles - 0.37

x miles - 1

$0.37x = 114$

$x = \frac{114}{0.37}$

$x = 308.11$

Rounding to the nearest mile

The total distance they will travel on their trip is 308 miles.

Nafessa graphs a line with slope 5 that passes through the point (3,-2).

Zina [86]

We know m = 5, x = 3, and y = -2, and that the point slope form is y = mx + b, so plugging these in we can solve for b;

-2 = 5 * 3 + b

-2 = 15 + b

b = -17

So the equation for the line would be;

y = 5x - 17

b is the y intercept, so that is answered (0,-17), to solve for the x intercept you have to plug 0 in for y in the equation, so;

0 = 5x - 17

17 = 5x

x = 17/5

So the x intercept would be (17/5,0)
