Complete the solution of the equation. Find the value of y when x equals -2. -4x+8y=-24 ​

Answers

Answer 1
Answer:

Answer:y=-4

Step-by-step explanation:

Multiply -4 by -2 you get positive 8 rewrite the equation subtract 8 from both sides that leaves you with 8y=-32 your final step is to divide both sides 8 that leaves you with -4 which is the answer.
Answer 2
Answer:

Answer:

y=-4

Step-by-step explanation:

-4(-2)+8y=-24

The negatives cancel out to make a positive.

8+8y=-24

subtract the number without a variable from the answer.

-24-8=-32

You are taking more away from the negative.

8y=-32

Divide the 32 by 8 to get your answer

-32/8=-4

Therefor your answer is y=-4

Identify the features of the graph

Answers

Answer:

Step-by-step explanation:

On seeing the graph we find that x intercepts are 1 and 5.

Also y intercept is 5

Vertex is at (3,-4) and also parabola is open up.

The possible equations can be of the form

y =a(x-1)(x-5)

y =a(x^2-6x+5)

When x=0, y =6

Hence 6 =5a

a =6/5

Solution is

y=(6)/(5) (x-1)(x-5)\n
There is a parabola that opens upwards with a line of symmetry at x=3 and the vertex is at (3, -4).

What is 53 and 1/3 as a decimal and please show how to turn it into a decimal

Answers

Well,
First I would like to explain how to convert a mixed number or fraction into a decimal.
1. First if it's a mixed number change it into an improper fraction.
2. After that divide the numerator by the denominator.
3. Your finished as simple as that.
NOW FOR THE ACTUAL ANSWER
well I turned 53 1/3 into an improper fraction which came out to be 160/3. After the division the decimal came to be 53.3333(etc)
I did it in the calculator and everything so I'm almost positive I did this correctly haha)
I hope I helped.
And I really enjoyed answering this since I knew you weren't just looking for an answer but for the reason behind it and how to do it hahah.

Answer:

53.3 (the three is repeated)

Step-by-step explanation: To convert 53 1/3 to decimal you can either use the long division method , or you can divide the numerator 160 ([53×3]+1) by the denominator 3 using a calculator.

Hope this helps!

Julian wrote this number pattern on the board 3,10,17,24,31,38 which of the numbers in Julian's pattern are composite numbers

Answers

The numbers in Julian's pattern are composite numbers are 10,24,and 38.

What is composite numbers?

A composite number is a positive integer that can be formed by multiplying two smaller positive integers. Equivalently, it is a positive integer that has at least one divisor other than 1 and itself.

here, we have,

3,10,17,24,31,38

Now, we get,

because 10 divided by 2 equals 5 so it's composite

because 10 times 1 isn't the only way to get the number 10,

same thing for numbers 24 and 38, 24 divided by 2 equals 12, 24 divided by 3 equals 8,24 divided by 4 equals 6

so it's composite,

and 38 divided by 2 equals 19.

Hence, The numbers in Julian's pattern are composite numbers are 10,24,and 38.

Which strategy would you use to find 2+8 explain how you decided

Answers

In this problem we need to make the following addition:

2 + 8

According to this I would use the following strategy:

1. Break apart strategy:


This strategy consists in the decomposition or separation of numbers. In this way, we may break number 2 and 8 down to place value and add each, starting with the 8 or keep one number intact and only break second number down by place value and adding each place. Anyway, using this strategy we have:

2 + 8 = ?

Thus, 2 breaks into 1 plus 1 (1 + 1), 8 breaks into 4 plus 4 (4 + 4), so by associative property:

(1+4)+(1+4) = 5+5=\boxed{10}


2. Explain how I decided.


The strategy of breaking apart numbers is an easy way to find additions. This strategy is amazing to add larger numbers. Therefore, we may break larger numbers up into hundreds, tens, ones, then add them.
You would use the addition strategy.

This is because there is a plus sign, which signifies addition. So, 2 + 8 = 10. If there had been a minus sign (-), you would be subtracting. Additionally, if there was a multiplication (x) or division (/) sign, you would multiply or divide, respectively.
