Factor equation. answer is -47, just puzzled on how to get it. step by step

Mathematics

Answer:

-47

Step-by-step explanation:

Original Equation:

f(-5)=3-2(-5)^2

Square the -5 (this cancels out the negative sign

f(-5)=3-2(25)

Multiply 2 and 25

f(-5) = 3-50

Subtract 50 from 3

f(-3) = -47

I'm a bit confused by what you mean factor the equation? Given the context. But I'm going to assume the equation is: f(x)=3-2x^2. Which isn't exactly factorable.

Answer:

-47

Step-by-step explanation:

First you use PEMDAS, so you start with the exponent.

-5^2 = 25

Then you multiply the -2!!! Not the 2 with the 25, multiplying the 2 is a common mistake.

When you multiply the -2, it results in:

3 - 50

= -47

Fill in the blanks to explain how Harry can check whether his solution is correct
Tresset [83]

<u><em>Answer is in bold</em></u>

Harry can first substitute 30 for t. He can then multiply \frac{1}{3} by 30 to get a product of 10. Since 15 is equal to 30 × 1/2, Harry's solution is not correct.

Hope this helps :)

Have a great day!

Which is the slope of the line y=−3x+2?y=-3x+2?
Morgarella [4.7K]
The slope is -3.
Finding slope can be easy if you just remember that the formula is set up as y=mx+b.
The number in the 'm' place is always the slope.
Example: y=4x+1, the slope would be 4 because it's in the 'm' place.
If you have trouble remembering which place the slope is, trying thinking about skiing or sledding; you can only sled or ski down a Mountain slope. Mountain starts with M.
M=slope.
Hope this helps :)

Elanso [62]

Answer:

<h3>The option B) is correct.</h3><h3>That is the line that makes the sum of the squares of the vertical distances of the data points from the line (the sum of squared residuals) as small as possible is correct answer</h3>

Step-by-step explanation:

Given that " The least-squares regression line "

The least-squares regression line is <u>the line that makes the sum of the squares of the vertical distances of the data points from the line (the sum of squared residuals) as small as possible.</u>

Therefore option B) is correct
