Answers

Answer:

80

Step-by-step explanation:

10+10= 20

20+20=40

40+40=80

Answer:

80, -160

Step-by-step explanation:

Each term is being doubled and the sign is reversing for every term. So -10 doubled and flipping the sign results in 20. Doubling 20 and flipping the sign results in -40. So on and so forth.

Answers

Answer:

y = -1/2x + 5/2

Step-by-step explanation:

Mid-point = ((-1 + 3) / 2 , (-5 + -1 )/ 2)

= (1 , -3)

Gradient = (-1 - -5 )/(-3 - -5)

= 2

m1_ = -1/2

y = mx + b    ( we have to find b)

y = -1/2 x + b     (we will use mid point x = x and y = y)

-3 = -1/2 (1) + b

-3 = -0.5 + b

b = -3 + 0.5

b = -5/2

so,

y = -1/2x + 5/2

The height of an acorn falling out of a tree is given by n = -16t2 + b. If an acorn takes 1 second to fall to the ground. What is the value of b?

Answers

Hope this helps , can I have the brainlessly plz x

Answer:

b = 16.

When the acorn reaches the ground the height n = 0. So we have:

-16(1)^2 + b = 0

-16 + b = 0

b = 16.

which equation represents the area,y, of the trapezoid​

Answers

Answer:

C.  y =  x^2 + 4x.

Step-by-step explanation:

Area of a trapezoid = (h/2)(a + b)   where h is the altitude and a and b are the lengths of the parallel sides.

So here

Area y  = (x/2)(8 + 2x)

= 8x/2 + 2x^2/2

= 4x + x^2.

Determine this one algebraically

Answers

Answer:

x = 5

y = 5

Step-by-step explanation:

In this question you need to solve one equation in order to plug the value into the second one and solve it as well. Lets start with the top one...

2x - x = 5

1x = 5

x = 5

Now we plug that value of x into the second equation

4x - 2y = 10

4(5) - 2y = 10

20 - 2y = 10

-2y = -10

y = 5

Finally, we can see that both x and y have a value of 5.

Jessica is shopping for a new car. She found a blue car that has a 12-gallon gas tank and can go 384 miles on one tank. She found a silver car that has a 14-gallon gas tank and can go 504 miles on one tank. Which car gets better gas mileage?

Answers

Answer:

Silver car

Step-by-step explanation:

It seems pretty hard but it's actually REALLY easy. gas mileage means the number of miles you can go on a particular amount of gallons. But the gallons have to be the same for both cars so that it's fair.

so let's go with 10 gallons. pretty broad number right?

so to get 12 gallons(the gallons for the blue car) to 10, We divide it by 12 then multiply it by 10. Try it yourself, (12/12)*10=???

then we do that to 384 (the miles for the blue car)

(384/12)*10=320

so 320 is the mileage for the first car. Repeat the steps for the silver car!

(14/14)*10=10

so then: (504/14)*10= 360.

So which is bigger, 320 or 360?

360 is bigger, meaning it has better gas mileage.

15.55 + 21.61 - 12.333 = 24.827

14 + 0.8 + 9.33 = 24.13

14.5 * 190 = 2755
