A TV that usually sells for $174.45 is on sale for 15% off. If sales tax on the TV is 8%, what is the price of the TV, including

nekit [7.7K]

Answer:

$160.14

Step-by-step explanation:

15% of 174.45 = 26.16

174.45 - 26.16 = 148.28

8% of 148.28 = 11.86

148.28 + 11.86 = 160.14

The midpoint of segment QR is M(-2, 9). One end point of segment QR is Q(-8, 12). Find the coordinates of the other endpoint, R.

DanielleElmas [232]

Here,

The midpoint of segment QR is M

m(-2,9) x3=-2,y3=9

Q=(-8,12)x1=-8,y1=12

R=x2,y2

we know that,

$\tt{ m=\dfrac{Q+R}{2} }$ ⠀

So,

x3= $\tt{\dfrac{x1+x2}{2} }$ ⠀

$\tt{-2=\dfrac{-8+x2}{2} }$ ⠀

$\tt{-2×2=-8+x2 }$ ⠀

$\tt{x2=8-4 }$ ⠀

$\tt{x2=4 }$ ⠀

x2=4

now we find the y coordinate y2.

y3= $\tt{\dfrac{y1+y2}{2} }$ ⠀

$\tt{9=\dfrac{12+y2}{2} }$ ⠀

$\tt{9×2=12+y2 }$ ⠀

$\tt{y2=18-12 }$ ⠀

$\tt{y2=6 }$ ⠀

y2=6

Now we get the two coordinate of R

so,

R=(x2,y2)=(4,6)

Which set of three numbers could be better he side lengths of a triangle

myrzilka [38]

The sides of a real triangle satisfy the triangle inequality, which just says any two sides add up to more than the third. It's strictly more; if two sides add up to exactly the third that's called a degenerate triangle. It's not a real triangle because the vertices are three collinear points.

The triangle equality fails when the sum of the two smallest sides fails to exceed the the largest side.

A. 4+6=10, degenerate triangle, not a real triangle

B. 4+7>7, isosceles triangles are real, SELECT

C. 4+3<10, not a real triangle

D. 4+7=11, degenerate triangle again

Can a real person please help me and not one of those bots that sends link

Alex_Xolod [135]

Step #1: Find the slope.

Slope is "rise over run" and see the attached graph to see

the rise = 1

the run = 4

and this gives a slope of 1/4.

Step 2: Find the y-intercept.

The y-intercept is where this graph hits the vertical axis. That happens at a height of 20, so your y-intercept is (0,20) and your b-value for the slope-intercept form is 20.

Step 3: Put it all together:

y = mx + b becomes

$y = \frac{1}{4} x + 20$
