Answer:

AB=5.83

Step-by-step explanation:

Distance Formula=

$\sqrt{(x2 - x1)^{2} - (y2 - y1)^{2} }$

Plugging our values in, we get:

$\sqrt{(7 - 2)^{2} + (4 - 1)^{2} }$

And if we solve it like this:

$\sqrt{25 + 9}$

We end up with:

$\sqrt{34}$

Which is about 5.83

linda scored 35, 47, and 42 points on three tests. how many points should she get on the fourth test to get an average score of

aliya0001 [1]

(35 + 47 + 42 + x) / 4 = 50
(124 + x) / 4 = 50....multiply both sides by 4, cancelling the 4 on the left side.
124 + x = 50 * 4
124 + x = 200
x = 200 - 124
x = 76 <===

What is the solution to this equation:<br> X+7=-8

Brilliant_brown [7]

Answer:

$\boxed {x = -15}$

Step-by-step explanation:

Solve for the value of $x$ :

$x + 7 = -8$

-Subtract both sides by $7$ :

$x + 7 - 7 = -8 - 7$

$\boxed {x = -15}$

So, the value of $x$ is $-15$ .

Question 19 makes no sense

gavmur [86]

Think: To write the equation of a line in slope-intercept form y=mx+b, you must have the slope (m) and the y-intercept (b).

g(0)= -6 tells us that the y-intercept is (0, -6). Thus, b= -6.

(0,-6) and (15,-9) are points on the line. Find the slope of the line. It is:
-9-(-6)
m = ------------- = -3/15 = -1/5
15-0

Thus, the equation of the line in question is y=(-1/5)x - 6.

Important that you understand that g(0)=-6 is also represented by (0,-6), and that -6 is the y-intercept.
