Answer:

Equation- p-6= -14

Answer- p=-8

Step-by-step explanation:

[tex]tn = t(n - 1)- 2.2[/tex]

common difference is

3.6 - 5.8 = -2.2

let T1 = 5.8

T2 = 3.6

assuming we are to find T2

T2 = T(2-1) -2.2

= T1 -22

= 5.8 -2.2

= 3.6

Answer:

20

Step-by-step explanation:

-3x+20=-5x+20+2x

reduced:

-3x+20=-3x+20

subtract 20 from each side

Then

-3x=-3x

Answer:

x+6

Step-by-step explanation:

5x-3(x-2)-x

5x-3x+6-x

combine like terms

x+6

Answer:

y=-3/2x+6

Step-by-step explanation:

You will need to find the equation of the line in slope-intercept form y=mx+b.

First, find the slope m using slope formula m = (y_2-y_1)/(x_2-x_1) which is m=(6-(-6))/(0-8)=-12/8=-3/2

Now that you found the slope, your equation intercept form looks like y=-3/2 x+b.

Both points (8, -6) and (0.6) belong to this line, therefore both points coordinates satisfy line above which means: 6=-3/2(0)+b (i used second point here)

Solving for b we will get y intercept which is b=6

Finally, the line that passes through points (8,-6) and (0,6) has equation: y=-3/2 x + 6

Answer:

1.6 hours so 96 minutes

Step-by-step explanation:

Answer:

F = 6

Step-by-step explanation:

find the constant of variation (k) first by using this formula:

f = k/d

plug in given info to find k:  3 = k/4 so k = 12

use 12 to find F:  F = 12/2

Answer: 57%

Step-by-step explanation:

Davis's monthly expenditure and his monthly salary was 3 : 7.

This means that for every $7 he received, he spent $3 out of it.

The amount he saved is therefore:

= 7 - 3

= $4

For every $7 received, he saved $4.

Percent = 4/7

= 57%

Answer:

1350

Step-by-step explanation:

Answer:

ok so I'm English not a hundred percent sure on your break down of money......so if I'm right in thinking that a nickel = 5 cents, dime = 10cents and a quarter =25cents

you add the amounts together

so 25 + 30 +20 = 75 cents.

there are 100 cents in a dollar so 100/100 X 75=75%

I have no idea how you got to 44%

Answer:A>

Step-by-step explanation:

Answer:

3:00

Step-by-step explanation:

Answer:

solution :

in the given figure AB=10.2cm, AC=14cm, AD=DC and AD perpendicular to BC.

now ,

in rt angle tirangle ADC,

angleACD=45 degree, angle DAC=45 degree now,

in triangle ABD,

angle BAD+angleABD+angleADB=180 DEGREE (sum of the sngle of triangle)

angle BAD+75+30=180

angle BAD=180-165      therefore,angle BAD=15

angle BAC =15+45=60

Area of triangle ABC=1/2×AB×AC×SIN 60

=1/2×10.2×14×√3/2

=61.83cm³ ans

Work Shown:

Plug in t = 2 and we get the following

[tex]a = 500*\left(\frac{3}{4}\right)^{t}\\\\a = 500*\left(\frac{3}{4}\right)^{2}\\\\a = 500*\left(0.75\right)^{2}\\\\a = 500*0.5625\\\\a = 281.25\\\\[/tex]

Answer:

slope:5

y intercept: -6

Step-by-step explanation:

Answer:

y=-9/5x-2/5

Step-by-step explanation:

Answer:

y=-9/5x-2/5

Step-by-step explanation:

Slope=m=Rise/Run=(y2-y1)/(x2-x1)=(-4-5)/(2-(-3))=(-9)/(5)=-9/5

So the equation becomes y=-9/5x+b

Plug in one of the given points:

y=-9/5x+b

-4=-9/5(2)+b

-4=-18/5+b

-0.4=b

b=-0.4

Therefore the equation of the line is y=-9/5x-2/5

To find the equation of the line, we need to figure out the slope and y-intercept.

To find the y-intercept, look at the number where the line intersects the y-axis. The number is 5. The equation so far is y = ?x + 5.

We still didn't figure out the slope yet. To figure out the slope, pick two points. Use the rise over run method. It is in the image below. The line is going up to the left, so the slope will be negative. Now we know the slope is -1/3. The equation now that we figured out the slope is y = -1/3x + 5.

I hope this helps you! Let me know if I got something wrong.

Answer:

There are two correct answers for this question depending on how you think of it.

3x or -3

Step-by-step explanation:

3x could be right because the rest of them are negative. But also on the other case -3 because the rest have x's and this one doesn't

Hope this helps :)
