Answer:

-2.8 = x

Step-by-step explanation:

-7х – 10 = 18 + 3x

+7x. +7x

-10. = 18+ 10x

-18. -18

-28. = 10x

/10. /10

-2.8 = x

1.   y = -⅔x + 490    

2.   I would start with the y-intercept(490) on the graph. Then from that point, I would use rise/run to find the next point: I would go down two points (because the slope is negative), and run three points to the right.

3.   f(x) = -⅔ + 490. The graph represents the total profits of last month.

4.   View file below.

5.   The graphs of these functions are similar in the fact that they are parallel to each other, therefore having the same slope.Both lines are also negative. They are different in that they do not have the same y-intercept or x-intercept.

Its due tomorrow need help!!

Let s represent the measure of the second angle.

The measure of the first angle is 15° less than the second, so we can represent the first angle by (s-15).

The measure of the third angle is 45° more than half the second, so we can represent the third angle by (45+(s/2)).

The sum of these angles is 180°, so we can represent the sum as

... (s-15) + s + (45+s/2) = 180

Collecting terms, we have

... 2.5s +30 = 180

... 2.5s = 150 . . . . . . subtract 30

... s = 150/2.5 = 60 . . . . divide by the coefficient of s

The first angle is 60-15 = 45.

The second angle is 60.

The third angle is 45+60/2 = 75.

_____

<u>Check</u>

The sum of the three angles is 45 +60 +75 = 180.

Help me i don’t know how to do this

Hi!

y = 16

x = 32

<h3 /><h3>In 30-60-90 triangles, the hypotenuse is double the length of the shortest leg, and the longer leg is \sqrt{3} times the shorter leg.</h3>

We are given the longest leg. To find the shortest leg, we must divide the longest leg value by \sqrt{3}

\cfrac{16\sqrt{3} }{\sqrt{3} }

The radicals cancel out and we are left with 16.

The length of y (the shortest leg) is 16.

Now, we also know that the hypotenuse is double the shortest leg. The shortest leg is 16, so if we double that, it's 32.
