x =_______ y =_______ 12. Find the values of x and y.

Answer:

D

Step-by-step explanation:

3/4 = 12/16

Answer:

1. Slyvia is wrong. You treat the numbers normally when dividing the left side, so 3.61/4.1 = .88. When dividing the exponents, you subtract the numerator from the denominator, so -11-7 = -18. So, you do have .88 * 10^-18, at first, but when you are working in scientific notation you want the decimal to be greater than so, which requires us to add an additional -1, to make it 8.8 instead of 0.88. This is because we want to move the decimal place left one more time. This results in our final answer being 8.8 * 10^-19, which is not Slyvia's answer.

2. Dylan's answer is correct. He subtracted the exponents correctly, then moved the decimal place over one place towards the left.

3. Ethan is wrong. He added the exponents, instead of subtracting. However, you cannot do this, because when you are dividing exponents, you must subtract.

Step-by-step explanation:

I have this acronym I learned called MADSPM, which has helped me a lot. I never learned it in Algebra, but I wish that they had taught it. Each letter corresponds with an exponent rule. If this makes sense, here is what it stands for:

When you multiply, you add.

When you divide, you subtract.

When there are parentheses, you multiply.

In this case, it was solely division. So, you just need to remember division = subtraction, when it comes to exponents.

Hopefully this helped. If you need me to explain it better, please let me know, and I will try. Thanks much & have a wonderful day!

Answer:

8. the length is 88/5cm or 17.6cm

Step-by-step explanation:

8.perimeter =2L + 2W

when you convert the width 42/5 = 8.4

so 52 = 2L + 2*8.4

52= 2L + 16.8

52 - 16.8 = 2L

35.2 = 2L

divide both sides by 2

L = 17.6cm

i would start by simplifying the equation to get y by itself, you don't need to do this, but it makes it a little easier

y + 2 = 3 ( x + 4) distribute the 3 through the parenthesis

y + 2 = 3x + 12. subtract 2 from both sides

y = 3x +10

now to fill in the chart simply plug in the value of x to see what value of y it produces

y = 3(-2) +10

y = -6+10

y = 4

(-2,4)

y = 3(0) + 10

y = 0 + 10

y = 10

(0,10)

y = 3(2)+10

y = 6 + 10

y = 16

(2,16)

y = 3(4) + 10

y = 12 + 10

y = 22

(4,22)

Answer:

Step-by-step explanation:

Answer:

r = - 11

Step-by-step explanation:

Calculate the slope m using the slope formula and equate to - 4

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (4, 5) and (x₂, y₂ ) = (8, r)

m = [tex]\frac{r-5}{8-4}[/tex] = [tex]\frac{r-5}{4}[/tex] = - 4 ( multiply both sides by 4 )

r - 5 = - 16 ( add 5 to both sides )

r = - 11

I think before we get to this answer we need to understand how roots of a quadratic equation works.

When a quadratic equation have 2 real roots such as a/b and c/d we can write the quadratic equation in factored form like this y or 0=(bx-a)(dx-c)

In this case we know the 2 roots are 5 and 2/3 and one of the factors is already x-5. so the other one according to the equation above that I wrote have to be 3x-2 and therefore the 3rd choice is correct.

Hope this helped you and if there is any questions about this please let me know in the comments.

Step-by-step explanation:

I think it is No am not sure exactly

The expanded form of this number 570.086 is,

⇒ (5 × 100) + (7 × 10) + (8 × 1/100) + (6 × 1/1000)

The value represented by a digit in a number on the basis of its position in the number is called a Place value.

Given that;

The number is,

⇒ 570.086

Now, We can expand the number as;

⇒ 570.086

⇒ 500 + 70 + 00 + 8/100 + 6/1000

⇒ (5 × 100) + (7 × 10) + (8 × 1/100) + (6 × 1/1000)

Thus, The expanded form is,

⇒ (5 × 100) + (7 × 10) + (8 × 1/100) + (6 × 1/1000)
