Step-by-step explanation:

23 + 4 ⋅ 8

I got the answer 55 so see what is close to 55

Answer:

2 ^ 3 + 4 * 8 = 40

Step-by-step explanation:

So going by the order of operations, PEMDAS,

There are not parenthesis so we can skip that part.

exponents on the other hand we have 2^3. Don't be fooled. It's not 2 * 3. What you have to do is multiply 2 by itself 3 times. So 2 * 2 * 2 = 8. Step one Done!

The M in PEMDAS is multiplication! So we solve that part next! 4 * 8 = 32. Step 2 Done!

Now for the final step, for A in PEMDAS you have to add both sums together. 8 + 32 = 40

Final answer: 40

Answer:

y=3/5x-3

Step-by-step explanation:

First, put the slope in point-slope form: y-y1=x(x-x1)

y+6=3/5(x+5)

Distribute 3/5 to (x+5) and simplify.

y+6=3/5x+3

y=3/5x-3

Answer:

y=2x+4 or f(x)=2x+4

Step-by-step explanation:

f(0)=4 is (0,4) and f(2)=8 is (2,8)

first, find the slope using the equation y2-y1/x2-x1

8-4/2-0

4/2

2

now, take one of the points, and put it into the equation y2-y1=m(x-x1) (m is slope)

take (0,4) for example

y-4=2(x-0)

y-4=2x

y=2x+4

y=f(x)

so, substitute as

f(x)=2x+4

Answer:

a) Function 1 has the greatest y-intercept

b) Only function 2 has a slope less than -2

c) Function 4 has the least steep slope

Answer:

1. Function 1

2. Function 2

3. Function 4

Step-by-step explanation:

y-intercept:   Function 1: 4, Function 2: 1, Function 3: -5, Function 4: -2

- Function 1 has the highest y-intercept

slope less than -2:  Function 1: 2, Function 2: -4, Function 3: 5, Function 4: -1

- Function 2 has a slope lower than -2

least steep graph: Function 1: steepness 2, Function 2: steepness 4, Function 3: steepness 5, Function 4: steepness 1

- Function 4 has the steepest graph

Answer:

-$5.50>x>$20

Elena has more than -$5.50 but less than $20.

Step-by-step explanation:

Ok, so the question says that Elena has -$5.50 in her account. That means that she owes someone ( the bank) $5.50.

Elena then mows the lawn which may have paid off her debt. But we don't know that for sure.

All they give us is that Elena has less than $20 in her bank account.

So your answer may look like this:

-$5.50>x>$20

Elena has more than -$5.50 but less than $20.

Elena earned, amount more than -$5.50 and less than $20 by mowing the lawn.

If two real numbers or the algebraic expressions are related by the symbols “>”, “<”, “≥”, “≤”, then the relation is called an inequality.

For example, x>3 (x should be greater than 3)

Given,

Account balance of Elena with her parents = -$5.50.

Which means she is in debt of $5.50.

Elena then  adds a certain amount of money to her balance by mowing the lawn,

which may have paid off her debt, that is not sure.

But,

Account balance of Elena after mowing the lawn is more than - $5.50 less than $20.

Let the money Elena earned by Elena earned mowing the lawn  = x

Then,

Possible amount she earned mowing the lawn = -$5.50 < x <$20.

Hence, Possible amount Elena earned mowing the lawn is

between -$5.50 and $20 = -$5.50 < x < 20.

Given,

Cherie accepted a job through an employment agency

The job pays $1,100 weekly.

The agency charges 22% of her first three months, pay.

22% of 1100 we have to calculate.

First we have to convert 22% to decimal

22/100=0.22

0.22×1100=242

Now for three months we need to calculate.

Answer:

  98 cm

Step-by-step explanation:

Area is the product of length and width. Fill in the given numbers in the formula and solve for length:

  A = LW

  8428 cm² = (86 cm)L

  L = 8428 cm²/(86 cm) = 98 cm . . . . . divide both sides by 86 cm

The length of the painting is 98 cm.

Step-by-step explanation:

The sum of interior angles is 180 degrees (Triangle Angle Sum Theorem). All interior angles of a triangle are more than 0° but less than 180°. The bisectors of all the three interior angles intersect inside a triangle at a point called the in-center, which is the center of the in-circle of the triangle.

Answer:

Number of calls expected in next week by manager = 7940

Average Number of calls that call center agent will attend in an hour =7 calls

It is also given that, Call center remain open for 10 hours 5 days a week.

Also, it is given that, full time agents work 40 hours a week but are only on call for 35 hours per week  ,Part time agents work 20 hours a week but are only on calls 17 hours per week .

⇒Number of hours worked by full time agents × Number of calls attended in an hour × Number of full time agents + Number of hours worked by Part time agents × Number of calls attended in an hour × Number of Part time agents ≤ 7940

Answer:

Option C

Step-by-step explanation:

Since, Price of cribs (P) are proportional to the proportional to the number of cribs (N) sold,

P ∝ N

P = kN

Here 'k' is the proportionality constant

To get the value of proportionality constant,

Since, value of 10 cribs is $1320

1320 = k(10)

k = 132

Therefore, equation will be

P = 132N

Option A

If number of cribs = 6

P = 132(6) = $792

False.

Option B

For N = 22

P = 132(22) = $2904

False.

Option C

For N = 40

P = 132(40) = $5280

True

Option D

For N = 55

P = 132(55) = $7260

False

Option E

For N = 80

P = 132(80)

  = $10560

False

Option F

For N = 250

P = 132(250)

  = $33000

False

Answer:

81/4

Step-by-step explanation:

Given the equation x^2 – 9x + 38 = 0

Subtract 38 from both sides

x^2 – 9x + 38 - 38= 0 - 38

x^2 - 9x = -38

Next is to complete the square, to do this  we will add the square of the half of coefficient of x to both sides as shown;

Coefficient of x is - 9

Half of -9 will be (-9/2)

Squaring the result will give (-9/2)² = 81/4

Hence the number that would have to be added to "complete the

square" is 81/4 to have;

x^2 - 9x + 81/4= -38 + 81/4

(x-9/2)² = -38 + 81/4

Hence the required value is 81/4
