Step-by-step explanation:

According to the given description, PS is the mid segment of the $\triangle TQR$

Therefore by Mid-segment Theorem:

$PS = \frac{1}{2} QR \\ \\ PS = \frac{1}{2} \times 32 \\ \\ PS =16 \:$

HELP PLS:

Answer:

Bruce's function:

$\displaystyle y=\frac{1}{4}x$

Felicia's function:

$\displaystyle y=\frac{1}{9}x$

Bruce's tiles cover more area

Step-by-step explanation:

Functions

We need to compare the area covered by tile of both Bruce and Felicia. We are required to find the function y, the area covered by the number of tiles he used, x.

We know the tiles used by Bruce cover 1/4 of a square foot, this is written as:

$\displaystyle y=\frac{1}{4}x$

To find the function for Felicia, we must use the data provided in the table

For example,

For x=9 tiles, y=1 sq ft

For x=18 tiles, y=2 sq ft

If we set

$\displaystyle y=kx$

We can find the value of k

$\displaystyle 1=9k$

$\displaystyle k=\frac{1}{9}$

Thus

$\displaystyle y=\frac{1}{9}x$

Testing the constructed function with x=18 and x=27

$\displaystyle y=\frac{1}{9}18=2$

$\displaystyle y=\frac{1}{9}27=3$

The function is complete and accurate.

Comparing both functions we see that Bruce's tiles cover more area because

$\displaystyle \frac{1}{4}>\frac{1}{9}$

A line that passes through the point (-1,3) has a slope of 2 . find another point on the line

Pie

Answer: (0, 5)

Step-by-step explanation:

Since the slope is 2 that means if we add 2 to the y we have to add 1 to the x value

(-1+1,3+2)

(0,5)

30. What is the solution to the system of equations? (1 point)

sesenic [268]

Answer:

Option B) (-1,7,5) is correct.

The solution to the given system of equation is (-1,7,5)

Step-by-step explanation:

Given system of equations are

$-7x-2y+z=-2\hfill (1)$

$6x-y-z=-18\hfill (2)$

$5x+4y-z=18\hfill (3)$

To find the solution of the given system of equations by using Elimination method:

Now adding equations (1) and (2)

$-7x-2y+z=-2$

$6x-y-z=-18$

_________________

$-x-3y=-20$

________________

$-x-3y=-20$

$-(x+3y)=-20$

$x+3y=20\hfill (4)$ (since "-" getting cancelled)

Now adding equations (1) and (3)

$-7x-2y+z=-2$

$5x+4y-z=18$

_________________

$-2x+2y=16$

________________

$-2x+2y=16$

$2(-x+y)=16$

$-x+y=8\hfill (5)$

Now adding equations (4) and (5)

$x+3y=20$

$-x+y=8$

_________________

$4y=28$

________________

$y=\frac{28}{4}$

Therefore y=7

Substituting y=7 in equation (4)

$x+3y=20$

$x+3(7)=20$

$x+21=20$

$x=20-21$

Therefore x=-1

Now substituting the values x=-1 and y=7 in equation (1) we get

$-7x-2y+z=-2$

$-7(-1)-2(7)+z=-2$

$7-14+z=-2$

$z=-2+7$

Therefore z=5

Therefore the solution to the given system of equation is (-1,7,5)

Therefore Option B) (-1,7,5) is correct.
