5y - 4x = 5. This gives you your points with a slope of 4/5

Answer:

y=\frac{4}{5}x+1

Step-by-step explanation:

We are given the slope, and the y-intercept. So we can use the slope-intercept equation. Which is as follows:

y=mx+b

where m is the slope and b is the y-intercept (the value of y when x=0).

The information that we have is that the slope of the line is:

m=\frac{4}{5}

and that the line crosses the y-axis at (0, 1).

From this point we can find the y-intercept b, because b is the value of y when x=0.

And since the line passes through (0, 1) when x = 0, y =1. Thus, the y-intercept is:

b=1

substituting the values of the slope and the y-intercept into the equation:

y=mx+b\\y=\frac{4}{5}x+1

the answer is:   y=\frac{4}{5}x+1

Dafna11 [192]

Answer:

$400 and $1,000

Step-by-step explanation:

Let us assume the x be the amount invested in 7% account

And, 600 + x be the amount invested in 9% account

Now the equation is

7x% + 9%(600 + x) = $118

0.07x + 54 + 0.09x = $118

0.16x = $118 -$54

0.16x = $64

x = $400

And, the other one is = $400 + $600 = $1,000

The radius of one sphere is twice as great as the radius of a second sphere. Find the ratio of their volumes.
Juliette [100K]
The ratio of the radii is 2:1, so the ratio of their surface areas is 4:1. <span>The area of a sphere is defined by 4 * pi * r^2 </span>

<span>So if the radius of the first sphere is 2r, then it would be (2r)^2 = 4r^2 </span>

<span>The rest is the same. So the ratio of their surface areas would be </span>

<span>4 * pi * 4r^2 divided by </span>
<span>4 * pi * r^2 </span>
