Two siblings' ages have a sum of 64 years. The older sibling was born 6 years before their young sibling.

Hi!

So we have to make a system of equations here.

Let sibling 1 be O and sibling 2 be Y (for older and younger)

So:

O + Y = 64

O = 64 - Y

(Either one works)

The older sibling is 6 years older.

O = Y + 6

Make everything in terms of Y.

64 - Y = Y + 6

Same to both:

58 = 2y

2y = 58

Divide by 2 on both sides:

y = 29

Since the older sibling is 6 years older:

29 + 6 = 35

Y = 29

O = 35

Let me know if you have any questions.

What is the equation in slope-intercept form of a line that passes through the points (5,3) (4,-3)
Darya [45]

Answer:

y=6x-27

Step-by-step explanation:

To find the slope of a line given 2 points; use this equation.

\frac{y_2-y_1}{x_2-x_1} = \frac{rise}{run}

(5,3) (4,-3)

x_1   y_1    \\x_2  y_2\\\\

\frac{3 - (-3)}{4-5} =\frac{-6}{-1}  = 6

slope = 6

as for y-intercept use this method in the attachment
