Answer:

statement A

Step-by-step explanation:

If the ratio

$\frac{QT}{TR}$ = $\frac{QU}{US}$

then TU is parallel to RS

$\frac{QT}{TR}$ = $\frac{32}{36}$ = $\frac{8}{9}$

$\frac{QU}{US }$ = $\frac{40}{45}$ = $\frac{8}{9}$

Since the ratios are equal then line segment TU is parallel to line segment RS

If f(x)=16x-30 and g(x)=14x-6, for which value of x does (f-g)(x)=0

tamaranim1 [39]

Answer:

x=12

Step-by-step explanation:

f(x)=16x-30 and g(x)=14x-6

(f-g)(x)=0

f(x)=16x-30 -(14x-6)

Distribute

= 16x -30 -14x +6

Combine like terms

= 16x-14x -30+6

2x-24

Set this equal to zero

2x-24 =0

Add 24 to each side

2x-24 +24=0+24

2x=24

Divide by 2

2x/2 =24/2

x = 12

Given A (-10,-3.5) and B (2, 5.5), find the coordinates of point P on AB so that P partitions AB in the ratio 5:1.

Sunny_sXe [5.5K]

$\textit{internal division of a line segment using ratios} \\\\\\ A(-10,-3.5)\qquad B(2,5.5)\qquad \qquad \stackrel{\textit{ratio from A to B}}{5:1} \\\\\\ \cfrac{A\underline{P}}{\underline{P} B} = \cfrac{5}{1}\implies \cfrac{A}{B} = \cfrac{5}{1}\implies 1A=5B\implies 1(-10,-3.5)=5(2,5.5)$

$(\stackrel{x}{-10}~~,~~ \stackrel{y}{-3.5})=(\stackrel{x}{10}~~,~~ \stackrel{y}{27.5})\implies P=\underset{\textit{sum of the ratios}}{\left( \cfrac{\stackrel{\textit{sum of x's}}{-10+10}}{5+1}~~,~~\cfrac{\stackrel{\textit{sum of y's}}{-3.5+27.5}}{5+1} \right)} \\\\\\ P=\left( \cfrac{0}{6}~~,~~\cfrac{24}{6} \right)\implies P=(0~~,~~4)$

Find the slope and y-intercept of the line represented by the table.<br> .<br> Please help me

Brilliant_brown [7]

Step-by-step explanation:

I cant see the question but use the formula

y=mx+b

m=slope

b=y-intercept

you can also use the equation

y2-y1/x2-x1 to find slope.

since its a table, you can plug the x (input) and y (output) coordinates of the table to find the slope.

Marco was paid $8 an hour and received $500 at the end of the summer as a bonus. Lupe was $11 an hour,but only received a $300 b

kolezko [41]

Answer:

Step-by-step explanation:

First make an equation,

8x+500=11x+300

Then, with pemdas, cancel out 300 and 8x

200=3x

Divide both sides by 3

Answer is 66.6 reapeating or about 67 hours
