Fred earned $22.50 in nine hours. how much did he earn after 4 hours? please show all your work

dusya [7]

I believe the answer is 10

22.50 divided by 9 to show how much for 1 hour. That is 2.5 so next 2.5 x 4 = 10

I don’t completely know if this is correct but I believe it is

-21x+3y=6 <br> How do you solve for y?

andreev551 [17]

All you've got to do is some simple algebra! When you solve for a variable, you are trying to get it alone on one side of the equation. So, we want something that looks like y = ...

First, add 21x to both sides of the equation. This will cancel out the -21x on the left side.
-21x + 3y = 6
-21x + 3y + 21x = 6 + 21x
3y = 21x + 6

Now, to get y alone, divide both sides of the equation by 3. This will cancel out the coefficient of 3 on the left side.
3y = 21x + 6
(3y)/3 = (21x + 6)/3
y = 7x + 2

There's the answer. Hope that helps! :)

Find the distance between each pair of points (-1,4) and (1,-1)

viktelen [127]

Answer:

d = $\sqrt{29}$

Step-by-step explanation:

$d= \sqrt{(x_2-x_1)^2+(y_2-y_1)^2} \\d= \sqrt{(1-(-1))^2+(-1-4)^2} \\d= \sqrt{(2)^2+(-5)^2} \\d= \sqrt{4+25} \\d=\sqrt{29}$

$\csc( \alpha ) = \frac{1}{ \sin( \alpha ) } \\$
------------------
$\sin( \alpha ) = \frac{11}{5 \sqrt{5} } = \frac{11 \sqrt{5} }{25}$

What is the equation of the parabola passing through the points<br>(0,6). (3, 15.6), and (10,-4)?

Novosadov [1.4K]

Answer:

y = -0.6x^2 + 5x + 6

Step-by-step explanation:

First, find the equation of a linear line that passes through the points (0,6) and (3, 15.6) in the slope intercept form, y = mx + b. We know that the line has a y-intercept of 6, so b = 6. Substitute 3 for x, 15.6 for y, and 6 for b to find m.

y = mx + b

15.6 = 3m + 6

9.6 = 3m

m = 3.2

y = 3.2x + 6

y = a(x - 0)(x - 3) + 3.2x + 6

y = a(x)(x - 3) + 3.2x + 6

Finally, substitute 10 for x and -4 for y in the equation above to find a.

-4 = a(10)(10 - 3) + 3.2*10 + 6

-4 = a(10)(7) + 32 + 6

-4 = 70a + 38

-42 = 70a

a = -0.6

Simplify to write in standard form.

y = -0.6(x)(x - 3) + 3.2x + 6

y = -0.6x^2 + 5x + 6
