Step-by-step explanation:

The answer is y(10° ) = -5351.5

A quadratic equation is a second-order polynomial equation in a single variable, x.

To write a quadratic relationship, consider the first three points: let it be A (0,70), B (1,69.7), and C (2,69.1).

To find the constant value, we substitute the first point in the quadratic function.

i.e   [tex]y=ax^{2} +bx+c[/tex]

At point A,  the equation becomes

y=0+0+c=70

i.e c=70

At point B, the equation becomes

a+b=69.7

At point C, the equation becomes

4a+2b=69.1

By solving the two equations above, we get the values of a and b.

a=-35.15 and b=104.85

Then the quadratic relationship becomes

[tex]y=-35.15x^{2} +104.85x+70[/tex]

At 11:00 A.M, the temperature becomes

y(10°) =-35.15(14*14) + 104.85(14)+70

y(10°)=-5351.5

The predicted temperature at 11.00 A.M is given by,  y(10°)=-5351.5

Answer:

x=5

Step-by-step explanation:

The absolute value is positive, so the equation stays the same:

2x-2=8

Add 2 on both sides:

2x=10

Solve:

x=5

Answer:

x=29/12

Step-by-step explanation:

Let's solve your equation step-by-step.

12x−21=8

Step 1: Add 21 to both sides.

12x−21+21=8+21

12x=29

Step 2: Divide both sides by 12.

12x/12 = 29/12

x=29/12

Answer:

  see below

Step-by-step explanation:

The idea is you're trying to find quotient values that get you close to the dividend value when they're multiplied by the divisor.

In the left panel, you are basically looking at 8/3 ≈ 2. Since that is 8 tens, the partial quotient is 2 tens, or 20. The value of that multiplied by the divisor (3) is what gets subtracted from 87 for the next effort.

That difference (27) is the new dividend at the top of the right panel. The line below it (-27) is the result of multiplying the partial quotient by 3. Hence, that partial quotient on the top line must be 9. We want the difference at the bottom of the right panel to be zero.

__

In case you didn't know already that 87/3 = 29, you could work backwards. Starting from 0 at the bottom right, you would fill in the boxes above that, then copy the top box in that panel (27) to the difference at the bottom of the left panel. Of course, the middle number there must be 60 for the difference to be 27. That is 3·20, meaning the partial quotient at left on the top line is 20.

There are 72 candles in each box

Step-by-step explanation:

Key skills needed for this problem: Division

1) The problem says there are 1728 candles in 24 boxes. We need to find the number of candles in one box.

2) To solve this equation, we need to divide 1728 by 24. 1728 divided by 24 is 72.

This means there are 72 candles in each box.

Hope you understood and have a nice day!! :D

Answer:

Answer: The equation in slope-intercept form is y=2x-11

Step-by-step explanation: Slope-intercept is y=mx+b where m is the slope and b is the y-intercept. To find the slope, you find the difference between the y values divided by the difference between the x values. -5-(-9) = 4, and 3-1 is 2. 4/2 is 2, so m = 2. Since the slope is 2, it states for every x you move on the right you move 2 up. But we are trying to get the y-intercept, so x = 0. We are subtracting 1 in our x value, so we move 2 downwards. We subtract 2 from -9 which gives us -11, which is our y-intercept.
