2(2/5) divided 2(-1/5)

we do PEMDAS meaning parenthesis first

2(2/5) = 4/5(calculator)

2/1x2/5=4/5

now

2/1x-1/5=-2/5

now we do division

4/5/-2/5 we get -2

-2

At Sally's market the ratio of apples to oranges is 4 to 7. If there are 28 oranges at her market
then how many apples are there?

Answers

Answer:

16 apples

Step-by-step explanation:

If the original ratio is 4:7.

Then we multiply both numbers by 4. Since 7 x 4 is 28.

So now you have (4x4):(7x4)

Your final ratio is 16 apples : 28 oranges

The equation y=2x+3 represents the cost y (in dollars) of mailing a package that weighs x pounds. a. Graph the equation. b. Using the graph, which is the best estimate for the cost to mail the package?
a. Graph the equation.

b. Using the graph, which is the best estimate for the cost to mail the package?

the packedge is 1.126 lb

c. Use the equation to find how much it costs to mail the package.

Answers

Answer:

B. Slightly more than $5

Step-by-step explanation:

y = 2x + 3

Firstly we check variables to make sure we understand.

y = dollars

x = pounds

On the scale, it says 1.126 lb. Which means 1.126 pounds.

And so, x = 1.126

y = 2x + 3

y = 2(1.126) + 3

y = 2.252 + 3

y = 2.252

The graph for part a and park b. It is underneath. I wrote 1.1, because it is rounded down from 1.126 lb, which is part b. The one with one line and no dots is part a.

Answers

Answer:

Step-by-step explanation:

2(m+2) = 22

Using the distributive property, you can multiply the 2 to both the "m" term and the "2".

2m + 2*2 = 22

2m + 4 = 22

Then you isolate the variable and solve.

2m = 22 - 4

2m = 18

m = 9

2(m + 2) = 22

2(m) + 2(2) = 22

2m + 4 = 22

2m = 22 - 4

2m = 18

2m / 2 = 18 / 2

m = 9

To distribute the 2 to each term inside the parentheses means to multiply the 2 by both terms in the parentheses so

2(m + 2) means (2 × m) + (2 × 4)

Write an equation of the parabola in vertex form. (-2, 6) (-1, 3)
An equation of the parabola is y=

Answers

The equation of the parabola is y = -3(x + 2)^2 + 6

How to determine the parabola equation?

From the graph, we have:

Vertex, (h,k) = (-2,6)Point (x,y) = (-1,3)

A parabola is represented as:

y = a(x - h)^2 + k

Substitute (h,k) = (-2,6)

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

Substitute (x,y) = (-1,3)

3 = a(-1 + 2)^2 + 6

Evaluate

3 = a + 6

Subtract 6 from both sides

a = -3

Substitute a = -3 in y = a(x + 2)^2 + 6

y = -3(x + 2)^2 + 6

Hence, the equation of the parabola is y = -3(x + 2)^2 + 6
