What is the y-intercept of the line -7x-5y=-45?

Answer:

-9

First, we must convert the equation into slope intercept form, by solving for y.

Step 1: Add 7x to both sides.

-7x-5y+7x=-45+7x-5y=-45+7x\\

Step 2: Regroup terms.

-5y=7x-45

Step 3: Divide both sides by -5.

y=-\frac{7x-45}{5}

y=-\frac{7}{5}x-9

Now we can determine the y-intercept by just looking at the equation! the y-intercept is the only constant, -9

​

I hope this helps!

A brainliest will be greatly appreciated!

Answer:

The y-intercept is at the point (0, 9).

Step-by-step explanation:

WE have the y intercept when x = 0:

-7(0) - 5y = -45

-5y = -45

y = -45/-5 = 9.

What is the slope of the line that passes through the pairs of points (-6,8) (2'3)
Alecsey [184]
Im pretty sure the answer is D, because if i used the right formula,
\frac{y2 - y1}{x2 - x1}
you should get this in the formula
\frac{8 - 3}{2 - ( - 6)}
\frac{5}{8}
a 2 subtracting a negative 6 makes it a positive, meaning your just adding 6 plus2, to get 8

The numerator of a fraction (which is in its simplest form) is 5 less than the denominator. If the numerator is multiplied by 2,
timama [110]
N = d - 5

2n/(d + 16) = n/d - 1/3 n/d
2n/(d + 16) = 2/3 n/d Divide by 2n
1 / (d + 16) = 1/3 d
Here's the tricky part.
d + 16 = 3d the two denominators are equal. the numerators are both 1.
16 = 2d
d = 8
so the numerator is d - 5
n = 8 - 5
n = 3

Let's see if it checks out.
n = 3
d = 8

2*3 = 6
8 + 16 = 24
New fraction 6/24 = 1/4
(3/8 - 1/3 ) = 1/8
3/8 - 1/8 = 1/4 so it checks with the original conditions put on it.

If andy pays 450 of the rent and mo pays 1/2 of the rent and charlie pays 25percent of the rent what is the overall rent
scoray [572]

Answer:

$1,800

Step-by-step explanation:

If Mo pays 1/2 of the rent then he is paying 50%. Charlie is paying another 25%. This leaves the remaining 25% that Andy pays. Since Andy's payment amount is 450 then that means that 450 is equal to 25% of the total rent. Therefore, we simply need to multiply this amount by 4 to get the 100% of the overall rent.

450 * 4 = $1,800

Finally, we can see that the total rent amount is $1,800
