Answer:

6x^2 + 4x

Step-by-step explanation:

g(x) + f(x)

= -8x^2 - 3x + 5 + 2x^2 + 7x - 5

= -8x^2 + 2x^2 - 3x + 7x + 5 - 5

Answer:

y = -3/4x + 7

Step-by-step explanation:

ok first u need to find the slope so use the slope equation for this (x2 - x1 over y2 - y1) so

1 - 4 = -3

8 - 4 4

so the m is -3/4

now you need to find the y intercept so pick one of the points (let's do (8, 1)) and plug that into the slope intercept form (y = mx+b)

so 1 = -3/4(8) + b

1 = -6 + b

+ 6 + 6

b = 7

so the equation is y = -3/4x + 7. hope this helps

Answer:

First, calculate the amount of sales tax by multiply the percent tax times the total cost:

0.07×600 =42

Next, add the amount of tax to the price of the computer:

600+42=642

$0.45792 more is she spending if she purchases the items in the city where she lives.

Given that, Jen purchased the items shown on the table. In the city she lives in, the sales tax rate is 7.15%. In another city, the sales tax rate is 6.35%.

We need to find out how much more is she spending if she purchases the items in the city where she lives.

A sales tax is a consumption tax imposed by the government on the sale of goods and services.

Now, the cost of the goods she purchased=11.99+35.50+6.75+3.00

=$57.24

The sales tax rate is 7.15%.

So, the sales tax=7.15% of 57.24

=$4.09266

The sales tax rate is 6.35%.

So, the sales tax=6.35% of 57.24

=$3.63474

Now, 4.09266-3.63474=$0.45792

Therefore, $0.45792 more is she spending if she purchases the items in the city where she lives.

Answer:

Lets see if the gallon fill the paint tray or not.

For that purpose we need to find out the volume of the paint tray and compare it with the volume of the gallon.

Given:

Length = 14 inches

Width = 10 inches

Depth = 4 cm = 1.57 inches

Volume = length x width x depth

Volume = 14 x 10 x 1.57

            = 220.47 inches cube

Volume of Gallon = 231 inches cube

Comparing the two volumes:

231 inches cube - 220.47 inches cube = 10.52 inches cube

Hence,

The paint will not fill the tray by 10.53 in3.

Step-by-step explanation:

To solve this inequality, we have to find x (or make x the subject of the inequality:

since     ⁻ˣ/₃  ≤ 6       [multiply both sides by 3]

               - x ≤ 18      [multiply both sides by -1; this flips the inequality sign]

To graph the inequality, draw the line x = - 18 with a solid line, and then shade the region that is x > -18.

We use a solid line because the point x = -18 is included. However, hypothetically,  if the inequality was x > -18 only, a broken line would be used to show that the line x = -18 is not included.

Hope this is the answer you need.

Step-by-step explanation:

Explanation:

Relation I has each item in the domain map to exactly one item in the range. So any input leads to exactly one output. Therefore, we have a function here.

In contrast, relation II has the input x = 0 lead to multiple outputs (namely y = 8 and y = -1 at the same time). This indicates we do not have a function here.

Relation III is the same as as the previous one. This time the input x = -2 maps to both y = 1 and y = -7 at the same time. We don't have a function here either.

If you wanted, you can plot these points on the xy plane to see that relations II and III fail the vertical line test. You would need to plot each relation separately.

Answer:

Step-by-step explanation:

X=16x

z=116

16x+112=128

360-128=232

232 divide by 2=116

Answer:

x = 9

z = 68

Step-by-step explanation:

For x, the top and bottom angles have the same value. To get x, you need to set up this equation: 12x + 4 = 112. Subtract 4 from itself and from 112. Your equation will then be 12x = 108. Divide 108 by 12, and then your answer is 9. So the value of x is 9.

For z, it's supplementary with the top angle. This means that the two angles combined add up to 180. So your question is: 112 + z = 180. Subtract 112 from 180, and then your answer is 68. So the value of z is 68.

Answer:

Annika is 15 years old and Rohan is 7 years old.

Answer:

11cm

Step-by-step explanation:

diameter = 16, r = 8 (16÷2)

π = 3.142

V=πr2h

2211.68 = π x 8^2 x h

2211.68 = 3.142 x 64 x h

2211.68 ÷ 64 ÷ 3.142 = h

h = 10.9986

= 11 cm (round off to nearest cm)

To check and confirm

V=πr2h

3.142 x 64 (8^2) x 10. 9986 = 2211.68

Yo Rick Astley

Step-by-step explanation:

y ∝ 1 √ x

y = k (1 √ x)

y = 7 when x = 36

7 = k ( 1 / √36)

7 = k (1/6)

k= 7 × 6

k = 42

If x = 4 then,

y = 42 ( 1/√4)

y = 42 ( 1/2)

y= 21
