IS IT A OR B OR C OR D

Note: Your answer choices remain a little unclear. But, I have solved the concept and solution, so you can easily figure it out.

Answer:

[tex]\left(-7x^0+5x^2-x+6\right)-\left(-8x^2+x+3\right)=13x^2-2x-4[/tex]

Step-by-step explanation:

Given the expression

[tex]\left(-7x^0+5x^2-x+6\right)-\left(-8x^2+x+3\right)[/tex]

solving the expression

[tex]=-7x^0+5x^2-x+6-\left(-8x^2+x+3\right)[/tex]

apply the rule: [tex]a^0=1,\:a\ne \:0[/tex]

[tex]=-7+5x^2-x+6-\left(-8x^2+x+3\right)[/tex]

[tex]=-7+5x^2-x+6+8x^2-x-3[/tex]

simplify

[tex]=13x^2-2x-4[/tex]

Therefore, the simplified form is:

[tex]\left(-7x^0+5x^2-x+6\right)-\left(-8x^2+x+3\right)=13x^2-2x-4[/tex]

Answer:

3x + 4y = 72

Step-by-step exlanation:

Number of pizzas = x

Number of sandwich trays = y

one large pizza can feed 3 players

one sandwich tray can feed 4 players

Total players = 72

I hope this helps! :)

Answer:

c=1/8

Step-by-step explanation:

2c-1/4=0

2c=1/4

2c/2=1/4/2

c=1/4x1/2

c=1/8

Answer:

[tex]B =120[/tex]

Step-by-step explanation:

Given

Represent Kitchen with K and Bedroom with B.

So:

[tex]K = 50ft^2[/tex]

[tex]K = 10 + \frac{1}{3}B[/tex] --- 10 more than 1/3 of Bedroom area

Required

Determine the bedroom area

The expression of K and B has been determined above.

The next step is to substitute 50 for K in the second equaion

[tex]K = 10 + \frac{1}{3}B[/tex]

[tex]50 = 10 + \frac{1}{3}B[/tex]

Multiply through buy 3

[tex]3 * 50 = 3 * 10 +\frac{1}{3}B * 3[/tex]

[tex]150 = 30 +B[/tex]

Make B the subject

[tex]B =150 - 30[/tex]

[tex]B =120[/tex]

Hence, the area of the bedroom is 120ft^2

Answer:

120

Answer:

[tex]y = 1500(0.024)^t[/tex]

Step-by-step explanation:

Given

[tex]a = 1500km[/tex] -- initial area

[tex]b = 2.4\%[/tex] -- rate

[tex]t = time[/tex] --- (years)

Required

Represent as an exponential function

An exponential function has the form:

[tex]y = ab^t[/tex]

Where

[tex]a = initial\ value[/tex]

[tex]b = rate[/tex] and [tex]b \ne 1[/tex]

[tex]t= time[/tex]

Substitute values for a and b, we have:

[tex]y = 1500 * (2.4\%)^t[/tex]

Convert percentage to decimal

[tex]y = 1500 * (0.024)^t[/tex]

[tex]y = 1500(0.024)^t[/tex]

Hence, the exponential function that represents the scenario is: [tex]y = 1500(0.024)^t[/tex]

Answer:

4/7

Step-by-step explanation:

6/7-2/7=4/7

Answer:

I believe that the answer is 4/7

Answer:

D. [tex]\displaystyle (x - 5)^2 = 36[/tex]

Step-by-step explanation:

All you are doing is converting this Quadratic Equation to a Vertex Equation in Vertex Form by completing the square:

[tex]\displaystyle [\frac{b}{2}]^2 \\ \\ x^2 - 10x - 11 = 0 → x^2 - 10x + 25 - 36 = 0→ (x - 5)^2 - 36 = 0 \\ \\ (x - 5)^2 = 36[/tex]

It is that simple, is it not?

Answer:

19

Step-by-step explanation:

You need to find the biggest and smallest number; 25,6

Then you subtract 6 from 25

25-6=19

I hope this helps!!!!!!!

Answer:

19

Step-by-step explanation:

The range is the difference between the highest and the lowest number

So 6, 12, 18, 20, 25 and 25-6 = 19

Answer:

3/2 or 1 1/2

Step-by-step explanation:

5÷3 1/3

5/1 ÷ 10/3 because you have to get it into an improper fraction form in order to divide

5/1 × 3/10 because you have to multiply the first number by the reciprocal

5  and 10 cancel out so you would have 2 at the bottom

3/2 or 1 1/2

Answer:

This is my other account.

Step-by-step explanation:

Answer:

x = -15

m = -3

Step-by-step explanation:

3x + 6 = x - 24

subtract the x from both sides to make the unknown variable on only one side of the equation

2x + 6 = -24

subtract the 6 from both sides to focus on the x

2x = -30

now divide both sides by 2 to get the x by itself

x = -15

that's your answer

10 - 2m = 16

subtract the 10 from both sides to focus on the m

-2m = 6

now divide both sides by -2 to get the m by itself

m = -3

that's your answer

Answer:

68.75

Step-by-step explanation:

Measure the length of the parallel sides and add them together. Then multiply this number by the height of the area. Then multiply by ½ or divide by two to find the square footage of the trapezoid.  

13.6 + 5.9= 19.5

19.5 + 8 = 27.5

27.5 x 5 = 137.5

137.5 x 1/2 = 68.75
