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.

Hope this helps!

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: 50 Words

Step-by-step explanation: We know Kyle can write a 300-word essay in an hour or 1 hour. We want to know how many words Kyle would have in his essay if he wrote one in 10 minutes.

First, find how many words Kyle can write per minute. Simply do this by dividing 300 by 60, since there are 60 minutes in a hour.

300/60 = 5. So, Kyle can write 5 words per minute.

Now, simply multiply 5 by 10 to find how many words Kyle would write in 10 minutes.

5 x 10 = 50. So, Kyle can write 50 words in his essay if he writes for 10 minutes.

Answer:

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:

60degrees

Step-by-step explanation:

Congruent means equal and equilateral triangle also means a triangle which has three sides equal.

So 60 degrees is the sides for each angle since when they are added they all add up to 180°

<AC=60°

<CB=60°

<AB=60°

60+60+60=180°

∆ABC=180°

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.

Answer:

Answer:

To make an equation, you need the slope and the y-intercept. If you only have 2 points, first get the slope, then use point-slope form.

Explanation:

Equations written in slope-intercept form (y=mx+b) require two pieces of information: the slope and the y-intercept, which is where the line crosses the y-axis. Point-slope form also involves the slope, which can be found from the two given points.
