Answer:

Step-by-step explanation:

Answer:

Option D

Step-by-step explanation:

Given expression is,

10(2x - 4) + 5 = 2x - 8

By using distributive rule,

20x - 40 + 5 = 2x - 8

20x - 35 = 2x - 8

Now we subtract 2x from both the sides of the equation

20x - 35 - 2x = 2x - 8 - 2x

18x - 35 = -8

By adding 35 on both the sides of the equation

18x - 35 + 35 = - 8 + 35

18x = 27

By diving with 18 from both the sides of the equation

[tex]\frac{18x}{18}=\frac{27}{18}[/tex]

x = [tex]\frac{3}{2}[/tex]

Therefore, Option D will be the correct option.

Answer:

inverseoperations

Step-by-step explanation:

An inequality is used to represent unequal expressions or numbers. The inequality describing the restrictions on the number of people possible in a van is [tex]160n + 200 \le 1200[/tex].

Given that:

[tex]Total = 1200[/tex] --- total pounds the van can contain

[tex]Weight = 150[/tex] --- average weight of each person

[tex]Gear = 200[/tex] -- weight of the gear in a van

[tex]Meal =10[/tex] -- weight of each meal

Assume there are n people.

The total weight (T) of the n people is:

[tex]T = Weight \times n[/tex]

Substitute [tex]Weight = 150[/tex]

[tex]T = 150 \times n[/tex]

[tex]T = 150n[/tex]

The total weight (M) of the meals is:

[tex]M= Meal \times n[/tex]

Substitute [tex]Meal =10[/tex]

[tex]M= 10\times n[/tex]

[tex]M= 10n[/tex]

Because the van cannot contain more than 1200 pounds, we use less than or equal to as the inequality.

So, the inequality is:

[tex]T + M + Gear \le 1200[/tex]

[tex]150n + 10n + 200 \le 1200[/tex]

[tex]160n + 200 \le 1200[/tex]

Hence, the inequality is: [tex]160n + 200 \le 1200[/tex]

The solution to the inequality is as follows:

[tex]160n + 200 \le 1200[/tex]

Collect like terms

[tex]160n \le 1200-200[/tex]

[tex]160n \le 1000[/tex]

Divide both sides by 160

[tex]n \le 6.25[/tex]

Remove the decimal part (do not approximate)

[tex]n \le 6[/tex]

Hence, the vehicle cannot contain more than 6 people.

Answer:

[tex]x_{1} =-5\\and \\x_{2} =-3[/tex]

Step-by-step explanation:

Solve by using factoring ------->

rewrite the expresion

x^2+8x+15=0

x^2+5x+3x+15=0

factor out x from the expression

x^2+5x+3x+15=0

xx(x+5)+3x+15=0

xx(x+5)+3(x+5)=0

factor out x+5 from expression

(x+5)x(x+3)=0

when the product of factors equals 0, at least one factor is 0

x+5=0

x+3=0

solve the equation for x

x = -5

x = -3

the equation has 2 solutions

[tex]x_{1} =-5, x_{2} =-3[/tex]

Quadratic formula

[tex]x=\frac{-8+\sqrt{8^{2} -4x1x15} }{2x1}[/tex]

any expression multiplied by 1 remains the same

[tex]x=\frac{-8+\sqrt{8^{2}-4x15 } }{2}[/tex]

evaluate the power

[tex]x=\frac{-8+\sqrt{64-4x15} }{2}[/tex]

multiply the numbers

[tex]x=\frac{-8+\sqrt{64-60} }{2}[/tex]

subtract the numbers

[tex]x=\frac{8+\sqrt{4} }{2}[/tex]

calculate the square root

[tex]x=\frac{-8+2}{2}[/tex]

write solution with a + sign and a - sign

[tex]x=\frac{-8+2}{2} \\x=\frac{-8-2}{2}[/tex]

calculate the value

[tex]x=-3\\x=-5[/tex]

the equation has 2 solutions

[tex]x=-3\\x=-5 \\and\\x_{1} =-5\\x_{2} =-3[/tex]

Slide 1.

Part A.

1. Band A:  y = 600

2. Band B: y = 1.25x + 350

Part B.

200 students.

Slide 2.

Part A.

Fixed cost = $150

Rate per student served = $6

Part B.

To figure the cost/person, look at the change in cost divided by the change in attendance.

For 100 students, cost = $750.

For 150 students, cost = $1050.

Change in cost = $300

Change in students = 50

Cost per additional student = 300/50 = $6

Assuming the costs are linear, then the price charged for 100 students reflects the cost per student + a 'fixed cost' that applies to the order as a whole.

100 * 6 = $600, so the fixed cost is 750-600 = 150.

We can check this notion by substituting in the other equation.

Does 150*6 + 150 = 1050? Yes.

150*6=900

900+150 = 1050.

Slide 3.

Part A.

She can choose either band, with $9.75 per ticket, if 200 students attend

Part B.

Check the cost using band A and 200 people, including food

600 + 150 + (6*200) =

600 + 150 + 1200 = $1950

Cost per ticket: = 1950/200 = $9.75

Cost using band B, 200 people, including food:

350 + 1.25(200) + 150 + (6*200) =

350 + 250 + 150 + 1200 = $1950

Cost per ticket: 1950/200 = $9.75

This means that Paula can choose either band, and the ticket cost will be the same.

Slide 4.

Part A.

Cost per ticket: $8.50 (of Band A, since it is the cheaper one)

Part B.

Check the cost using band A and 300 people, including food

600 + 150 + (6*300) =

600 + 150 + 1800 = $2250

Cost per ticket: = 2250/300 = $8.50

Cost using band B, 200 people, including food:

350 + 1.25(300) + 150 + (6*300) =

350 + 375 + 150 + 1800 = $2675

Cost per ticket: 2675/300 ≈$8.92

Which means that in this scenario is Band A is less expensive.

Answer:

C.

Step-by-step explanation:

Hi there!

We know that [tex]x^0[/tex] is equal to 1 because any number raised to the zero is always going to be 1.

With that out of the way, we are left with [tex]x^-^3/1[/tex], which is equivalent to [tex]x^-^3[/tex]

Using negative exponent rules,

The expression is flipped and the -3 becomes a positive 3.

It will look like this

[tex]\frac{1}{x^3}[/tex]

Your answer is C.

Answer:

y = 147.56 - 10.78x

Step-by-step explanation:

Given :

x = 10.2 ; y = 37.6 ; Sx = 2.8 ; Sy = 30.8 ; r = - 0.98

The regression equation :

y = mx + c

Where ;

m = slope ; c = intercept

Slope = r * (Sy/Sx)

Slope = - 0.98 * (30.8 / 2.8)

Slope = - 0.98 * 11 = - 10.78

To obtain c :

y = mx + c

y - mx = c

37.6 - (-10.78)(10.2) = c

37.6 + 109.956 = c

147.556 = c

Hence, equation becomes :

y = 147.556 - 10.78x

y = 147.56 - 10.78x

Answer:

y = 147.56 + -10.78x

Answer:

  y = 15·2.1599^x

Step-by-step explanation:

We know that the number changed by the ratio 1523/15 = 101.5333... in 6 days, so the daily multiplier is the 6th root of this:

  b = 101.5333...^(1/6) = 2.1599 . . . rounded to 4 dp

Of course, the coefficient 'a' in the equation is the initial number, 15.

Your exponential equation is ...

  y = 15·2.1599^x

  a = 15

  b = 2.1599
