Find the x and y intercept of 8x+10y=15. NO LINK TO ANSWER PLEASE TYPE

oee [108]

Answer:

x intercept: 15/8 and yintercerpt is 3/2

Step-by-step explanation:

to find y intercept you have to put equation in standard form.

10y=-8x+15

y=--4/5x+3/2

x intercept is when y=0, so we plug in 0

0=-4/5x+3/2

4/5x=3/2

x=15/8

What is the midpoint of RS with endpoints R (-8, 3) and S (9, – 7)?

lubasha [3.4K]

Answer:

Midpoint coordinates are $(x,y) = (\frac{1}{2} , -2)$

Step-by-step explanation:

The Coordinates of R = (-8,3)

The Coordinates of S = (9, -7)

Let M be the mid point of M and its coordinates by (x,y)

Now, by mid point formula,

$(x,y) = (\frac{x_1 + x_2}{2} ,\frac{y_1 + y_2}{2} )$

⇒ $(x,y) = (\frac{1}{2} ,\frac{-4}{2} ) = (\frac{1}{2} , -2)$

So, the midpoint coordinates are $(x,y) = (\frac{1}{2} , -2)$

Dan is 18 years old. In 6 years he will be 4/5 the age of his brother Nick. How old will

attashe74 [19]

4 times 6 is equal to 24 so I did the same to 5 ( because 4/5) and then I got 30 so.
In six years he will be 24 and his brother will be 30 but in 4 years his brother Nick will be 28.
