Solving for y. - y = -2x -5

Mathematics

1 answer:

Effectus [21]3 years ago

Answer:

y = 2x+5

Step-by-step explanation:

Add y on both sides, this cancels out the y on the left side

add 2x and add 5 on both sides, this cancels out the -2x and the -5 on the left side.

OR

Divide/Multiply both sides by -1, as it will cancel out the negatives as two negatives make a positive.

If you needed a value for y, more info is needed.

hope this helps (:

please rate, thanks !

Which of the following equations describes the graph?

Artist 52 [7]

Answer:

y = 1/2x^2 - 2x + 1

Step-by-step explanation:

The equation of the parabola in vertex form is y = 1/2 (x - 2)^2 - 1. By finding the vertex at (2,-1) we plug in the point into the formula y = a(x-h)^2 + k. To convert it to standard form like the equations listed, multiply through the distributive property to clear the parenthesis.

y = 1/2 (x-2)(x-2) - 1

y = 1/2 (x^2 - 4x + 4) - 1

y = 1/2x^2 - 2x + 2 - 1

y = 1/2x^2 - 2x + 1

A statue height is 2 meters and 30 cm is how tall is the statue in millimeters I'm in 6th btw ;-;!

disa [49]

Answer: 2300.

Explanation:
There are 1000 millimeters in a meter.
There are 100 centimeters in a meter.
There are 10 millimeters in a meter.

Multiply the number of meters by 1000 giving us 2000.
Multiply the number of centimeters by 100 giving us 300.

Add the numbers together to get 2300.

Bonus info
Milli: 1000
Centi: 100

That information should probably help you with other measurement conversions when you take chemistry or physics.

Have a nice day! :) Good luck with the rest of middle school.

Here are the first four terms of a quadratic sequence

mixer [17]

Answer:

2n² + n

Step-by-step explanation:

Given sequence:

3, 10, 21, 36, ...

Work out the first differences between terms:

$3 \underset{+7}{\longrightarrow} 10 \underset{+11}{\longrightarrow} 21 \underset{+15}{\longrightarrow} 36$

As the first differences are not the same, work out the second differences.

$7 \underset{+4}{\longrightarrow} 11 \underset{+4}{\longrightarrow} 15$

As the second differences are the same, the sequence is quadratic and will contain an n² term.

The coefficient of n² is always half of the second difference. Therefore, as the second difference is 4, the coefficient of n² is 2.

To work out the nth term of the sequence, write out the numbers in the sequence 2n² and compare with the given sequence:

$\begin{array}{|l|c|c|c|c|}\cline{1-5} n & 1 & 2 & 3 & 4 \\\cline{1-5} 2n^2 & 2 & 8 & 18 & 32\\\cline{1-5} \sf Operation & +1 & +2& +3& +4\\\cline{1-5} \sf Sequence & 3 & 10 & 21 & 36\\\cline{1-5}\end{array}$

Therefore, we need to add n to 2n² to match the sequence.

Therefore, the nth term of this sequence is 2n² + n.

Correct Answers only please! I only have two attempts on this assignment, and I cannot retake it. I've already tried the answer

Strike441 [17]

Answer: A. x= 5"

Step-by-step explanation:

ORIGINAL/NEW = 11"/7" = 8.5"/x

x = 7" x 8.5"/11" = 59.5"/11 = 5.409 ≅ 5.41"

If we wanted to keep most of the engraving, we would adjust the larger dimension, but we have been asked to adjust one dimension to 5", since it is said that C. x = 5.41 is incorrect

Then we will adjust

ORIGINAL/NEW = 11"/y = 8.5"/5"

y= 11" x 5"/8.5" = 6.47"

Then the new dimensions of the paper are 6.47" x 5" to fit an 7" x 5" frame

Answer: A. x= 5"
