Answer:

x = 6 , y = 8 ( 6 , 8 )

Step-by-step explanation:

If we solve the linear system that you gave us,

y = 5x – 22

3x +2y=34

We get that x is 6 and y is 8.

In other words, since it's a point, it should be, ( 6 , 8 )

Find an equation of a line with the x- and y-intercepts below. Use exact fractions when necessary.

Ludmilka [50]

Answer:

The line with the x- and y-intercepts below has the following equation:

$f(x) = \frac{5x}{7} - 5$

Step-by-step explanation:

The equation of the line has the following format:

$f(x) = ax + b$

We are given two points, we are going to substitute them into the above equation, and find the equation of the line given the conditions.

Solution

Starting from the y-intercept makes the solution easier, since the term a is multiplied by 0

y-intercept -5

This means that when $x = 0, y = f(x) = -5$ , so:

$f(x) = ax + b$

$-5 = a(0) + b$

$b = -5$

For now, the line has the following equation:

$f(x) = ax - 5$

x-intercept 7

This means that when $y = f(x) = 0,x = 7$ , so:

$f(x) = ax - 5$

$0 = 7(a) - 5$

$7a = 5$

$a = \frac{5}{7}$

So, the line with the x- and y-intercepts below has the following equation:

$f(x) = \frac{5x}{7} - 5$

Solve each system using elimination. 3x+3y=27 x-3y=-11

Natalija [7]

Answer:

x=4

y=10

Step-by-step explanation:

3x +3y = 27

x - 3y = -11 (add these up so 3y will be eliminated and you'll have x only)

4x = 16

now let's eliminate x (you can put 4 instead of x though)

3x + 3y = 27

-3/ x -3y= -11 (multiple the the 2nd equation with -3 to eliminate x )

3x + 3y =27

-3x + 3y =33

6y = 60

There is 5/6 of an apple pie left from dinner. Tomorrow, Victor plans to eat 1/6 of the pie that was left. How much of the whole

Lady_Fox [76]

5/6 = 83%
1/6= 16%

83% of the apple pie was left from dinner.
Victor is gonna eat 16% of the pie tomorrow
You have to subtract 16% from 83%
In other words 5/6-1/6

The denominators are same so you don't have to do anything to them
5/6 - 1/6

5-1=4

4/6 of the pie would be left
In simplest form it would be

4/6 <span> ÷2</span>
=2/3

2/3 is in simplest form
