Answer:

30

Step-by-step explanation:

Start by substituting

2(5+3²) +2 = ___

Parenthesis

3²= 3 · 3 = 9

add that to 5 = 14

2(14) +2 = ___

2 times 14 = 28.

28 + 2 = 30

Answer:

30.

Step-by-step explanation:

2(5+ x^2)+ y

x=3, y=2

Using the given information for x and y and distributing that into the equation, the equation becomes:

2(5+ 3^2)+ 2

Now, use order of operations or PEMDAS (parenthesis, exponents, multiplication, division, addition, subtraction) to solve the problem.

The answer you should get is 30. :,)

Answer:

After the discount $527.12

You save $71.88

Step-by-step explanation:

Answer:

Substitute y=x-2y=x−2 into y=-0.5x+4y=−0.5x+4.

x-2=-0.5x+4x−2=−0.5x+4

2 Solve for xx in x-2=-0.5x+4x−2=−0.5x+4.

x=4x=4

3 Substitute x=4x=4 into y=x-2y=x−2.

y=2y=2

4 Therefore,

\begin{aligned}&x=4\\&y=2\end{aligned}

Answer:

Steak:$38

Chicken:$24.75

Fish:$16.31

Total:$79.06

Step-by-step explanation:

8 x 3 1/2 = 8 x 7/2 = 56/2 = 28

4 2/4 x 5.50 = 4 2/4 x 5 1/2 = 18/4 x 11/2 = 198/8 = 24 6/8 = 24.75

2 1/4 x 7.25 = 2 1/4 x 7 1/4 = 9/4 x 29/4 = 261/16 = 16 5/16 = 16.312 (round it and get 16.31)

38 + 24.75 + 16.31 = 79.06

Answer:

(-4,2)

Step-by-step explanation:

Just had the test for this thing lol.

so what you do is find the point Y.

then subtract 1 from it's x axis then add 2 to it's y axis.

work

Answer:

The missing number is 14.

Step-by-step explanation:

Here is the pattern of the numbers

1.) A number.

2.) That number minus 5.

3.) That number plus 2.

4.) The cycle starts over.

17 - 5 = 12

12 + 2 = 14

Therefore, the missing number is 14.

Answer:

70 + 95 = 5(14 + 19)

Step-by-step explanation:

To factor the expression, 70 + 95, using the GCF, take the following steps:

✔️Find the prime factors of each number:

Prime factors of 70 = 2 × 5 × 7

Prime factors of 95 = 5 × 19

Multiply the factors that both numbers have in common to get the GCF.

This, both number have only one factor in common which is 5.

Therefore, the GCF of 70 and 95 is 5.

✔️Factoring the experession given using the GCF, we have:

70 + 95 = 5(14 + 19)

Answer:

$160

Step-by-step explanation:

A = $1,160.00

I = A - P = $160.00

Equation:

A = P(1 + rt)

Calculation:

First, converting R percent to r a decimal

r = R/100 = 4%/100 = 0.04 per year.

Solving our equation:

A = 1000(1 + (0.04 × 4)) = 1160

A = $1,160.00

The total amount accrued, principal plus interest, from simple interest on a principal of $1,000.00 at a rate of 4% per year for 4 years is $1,160.00.

Answer:

80 tickets

Step-by-step explanation:

Given the profit, y, modeled by the equation, y = x^2 – 40x – 3,200, where x is the number of tickets sold, we are to find the total number of  tickets, x, that need to be sold for the drama club to break  even. To do that we will simply substitute y = 0 into the given the equation and calculate the value of x;

y = x^2 – 40x – 3,200,

0 = x^2 – 40x – 3,200,

x^2 – 40x – 3,200 = 0

x^2 – 80x  + 40x – 3,200 = 0

x(x-80)+40(x-80) = 0

(x+40)(x-80) = 0

x = -40 and x = 80

x cannot be negative

Hence the total number of  tickets, x, that need to be sold for the drama club to break  even is 80 tickets

Answer:

x = 13

Step-by-step explanation:

154 + 13 = 167

so 180 minus 167 and you get 13

all interior angels of a tringel should add up to 180

Answer:

4. The quotient of 0 and a is undefined.

Step-by-step explanation:

Let's examine each statement to see which is true or untrue.

✔️Statement 1:

a is a negative number. b is also a negative number. A negative number dividing another negative number would give us a positive number. That is the quotient of a and b would be positive.

Statement 1 is true.

✔️Statement 2:

Dividing 0 by any number would always give us 0. Therefore the quotient of 0 and c would be 0.

Statement 2 is correct.

✔️Statement 3:

c is a positive number. b is negative number. Positive divided by negative = negative.

Statement 3 is correct.

✔️Statement 4:

Dividing 0 by any number would give us a quotient of 0.

Statement 4 is incorrect. It is incorrect because ⁰/a = 0. But a/0 = undefined.

=============================================

Explanation:

Ignoring the variables for now, the GCF of 18 and 12 is 6. This is the largest factor found in both values

Now let's consider the variables. Both terms have an 'x' in them, but not a y. This means x will be tacked on the 6 we found earlier to get the overall GCF to be 6x.

Note how

18x + 12xy = 6x*3+6x*2y = 6x(3+2y)

Showing we can factor out the GCF using the distributive property.

Answer:

2) 160

3) 320

Step-by-step explanation:

you want to find out the slope so use the formula

y₂-y₁/ x₂-x₁ and plug in the numbers

320-80=240

4-1=3

divide 240/3= 80

multiply 80 * (x) so if we try and find x=2 it would be 160

80 * 3 = 240

check your work by multiplying 80 and 4 (320) which is your y value! hope this helps!

The discount is $49.90 the final price is $449.10

Step-by-step explanation:

Answer:

no, it is not

Step-by-step explanation:

STEP 1: Simplify (x−1)(x+2).

[tex]x^2+x-2=x+3[/tex]

STEP 2: Move all terms containing x to the left side of the equation.

[tex]x^2-2=3[/tex]

STEP 3: Move all terms not containing x to the right side of the equation.

[tex]x^2=5[/tex]

STEP 4: Take the square root of both sides of the equation to eliminate the exponent on the left side.

[tex]x=[/tex]±[tex]\sqrt{5}[/tex]

STEP 5: The complete solution is the result of both the positive and negative portions of the solution.

[tex]x=\sqrt{5} ,-\sqrt{5}[/tex]
