Solve the system of equations by graphing. <br><br> x+y=3<br> y=2x−15
Stella [2.4K]

Hey!

Hope this helps...

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

x + y = 3

x = 3 - y


y = 2x - 15

y = 2(3 - y) - 15

y = 6 - 2y - 15

y = -2y - 9

3y = -9

y = -3


y = 2x - 15

-3 = 2x - 15

-2x = -12

x = 6


So...

The answer is: (6, -3)

Write the equation of a line parallel to f(x)=1/2x+1 and passing through the point (-5, -2).
STALIN [3.7K]

Answer:

y = 1/2x + 1/2

Step-by-step explanation:

y = 1/2x + b  [Parallel lines have the same slope but different y-intercepts]

-2 = (1/2)(-5) + b  [Plug in the coordinates (-5,-2) to find the y-intercept b]

b = 1/2  [Solve for b]

y = 1/2x + 1/2

What are the minimum, first quartile, 20 70 13 15 23 17 40 51
malfutka [58]

Answer:

Minimum 13

First quartile 16

Step-by-step explanation:

Rewrite the sample 20 70 13 15 23 17 40 51 in ascending order:

13  15  17  20  23  40  51  70

The minimum is 13.

The median is the middle number

13  15  17  20  23  40  51  70

The middle number between 20 and 23 is

\dfrac{20+23}{2}=21.5

Consider first half of the sample

13  15  17  20

The first quartile is the middle number of this part. The middle number of

13  15  17  20

is

\dfrac{15+17}{2}=16
