Combine like terms to simplify the following expression : 12x+4y-3x+2-8y^2+9

Answer:

This is in slope intercept form

y = mx + b

m is the slope b is the .y intercept so the y intercept is -6

Step-by-step explanation:

Answer:

-6

Step-by-step explanation:

We know this because the equation is y=mx+b. M represents the slope and b represents the y-intercept. In this case, -6 is in the y-intercept’s place. Therefore, we know that -6 is the y-intercept.

Answer:

If a sales person wants to earn $600 in 1 week they have to make $1000 dollar sale or a bunch of sales that can make $1000

Step-by-step explanation:

Because $600 - $450 gives you $150, and $150 is 15% of her sales to if we were to divide $150 by 0.15 ( 15% in decimal for ) we would get $1000 meaning 15% of 1000 is 150.

Hope this helps :)

Answer:

Zero slope is the answer

Answer:

Step 1: Subtract 8 to -10 because it is a positive

Step 2: Divide 2r by -18

Answer:

The answer is 11/14 ft^2 or pi/4 ft^2

Step-by-step explanation:

The area of the sector bounded by that angle measure will be the area of the circle divided by 4

Area of the circle is;

pi * r^2

so the area here is;

22/7 * 1 * 1 = 22/7

divide this by 4

= 22/28 = 11/14 ft^2

Answer:

800mph

Step-by-step explanation:

Step one

Given data

time taken= 3 h 33 min

= 3.55 hours

distance = 2840 miles

Step two:

from speed= distance/time

substitute

speed= 2840/3.55

speed= 800mph

Hence the speed is 800mph

Answer:

[tex]d = 8 + 2t[/tex]

Step-by-step explanation:

Given

[tex]Rate = 2km/trip[/tex]

[tex]Base\ Cycle = 8km[/tex]

[tex]d = total\ distance[/tex]

[tex]t = cycles[/tex]

Required

Determine the expression for this scenario

The expression can be derived from:

[tex]Total\ Distance = Base\ Cycle + Rate * Cycles[/tex]

Substitute d for Total Distance and t for cycles

[tex]d = Base\ Cycle + Rate * t[/tex]

Substitute values for Base Cycle and Rate

[tex]d = 8 + 2* t[/tex]

[tex]d = 8 + 2t[/tex]

Answer:

180 miles

Step-by-step explanation:

if you divide 72 by 4 you can see what 1/10 of the trip is, which is 18. 18 times 10 (since 18 is one tenth of it) equals 180. hope this helps!

Answer:

f(x)=0.5x+3.5, x<1

f(x)=-2x+6, x>1

Step-by-step explanation:

Find the Point of Interest, which is at x=1 because the direction changes. Find the slope (rise/run) of the line on the left which is 1/2 or 0.5. Find the y-intercept by plugging in the given point: (-3, 2). 0.5(-3)+c=2 so the y-intercept is 3.5. Do the same for the line on the right.

Answer:

1

Step-by-step explanation:

The slope of the line is 1. To find slope use the formula [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex], this calculates the change in y over the change in x. So plug in the known values [tex]\frac{0+3}{3-0}[/tex], this equals 3/3 or 1. This means every time y increases by 1, x will also increase by 1.

Answer:

Yes, Teacher

Step-by-step explanation

Answer:

A

Step-by-step explanation:

Δ NLP and Δ NMO are similar, thus the ratios of corresponding sides are equal, that is

[tex]\frac{NL}{NM}[/tex] = [tex]\frac{NP}{NO}[/tex] , substitute values

[tex]\frac{15+x}{15}[/tex] = [tex]\frac{28}{20}[/tex] ( cross- multiply )

20(15 + x) = 420 ( divide both sides by 20 )

15 + x = 21 ( subtract 15 from both sides )

x = 6

Answer:

18. 56

19. 132

20. 55

21. 120

22. 129.5

23. 61.3

Step-by-step explanation:

First look at the lines arrangment

angle 1+angle 5=180 and according to corresponing angles theorem angle 5 and angle 2 are equivalent. Angle 1+4=180

180-124=56

Angle 2+3=180

180-48=132

According to corresponding angles

angle 4=angle 7 and angle 7=angle 2 meaning angle 4=5

so angle 5=2

Like everything opposite to each other is conr=gruent

angle 8=angle 1 and angle 1=angle 6

means both angle 6 and 8 are congruent.

LOOK angle 7+3=180 means angle 2+6=180

so if ANGLE 7=50.5

6=3

180-50.5=129.5

23. angle 6 and 3 are congruent and as you know angle 7+3=180 and angle 2+6=180

angle 3+angle 6=180

180-118.7=61.3

18. Measure of angle 1=124 then angle 4=56

19.Angle 2= 48 then angle 3=132

20.Angle 4=55 then angle 2=55

21. angle 6=120 then angle 8=120

22.angle 7=50.5 then angle 6=129.5

23.angle 3=118.7 then angle 2=61.3

Hope this helps!!
