• Oscar → x

• Lois → (x + 3)

Answer:

Step-by-step explanation:

(a) 2.49 * 6 = 14.94 <== what they spent on goodie bags

(b) 150 for 8 hrs = 150/8 = 18.75 per hr

(c) 182.53 - (150 + 14.94) = 182.53 - 164.94 = 17.59...they spent 17.59

Answer:

1st Q: C. Algebraic Expression; it consists of numbers and a variable.

2nd Q: D. The number of times Chris washes the car.

Step-by-step explanation:

1st Question:

Numerical Expression: Contains numbers and operations. Numerical expressions are your typical 2 + 2 equations. The ones you start learning in Kindergarten with just numbers and different operations such as addition, subtraction, division, and multiplication.

EX: 108 - 24 = ?

? = 84

Algebraic Expression: Contains numbers, operations, and variables. They are the same as normal, numerical expressions with the exception that it also has letters, or variables.

EX: 2x + 3 = 7

x = 2

__________________________________

2nd Question:

Amount Chris earns per wash: $10.00

# of times Chris washes the car: x

So 10x means what...?

10 = earns per wash

x = times washed the car

Multiply 10 by x to find the total Chris earns for the number of times he washes the car, x.

(Just as a reference, this would be counted as an Algebraic Expression).

Hope this helps! :)

(Lmk if you don't understand the explanation for the 2nd Q)

1. horizontal shrink by factor of 2/3 means multiply outside the f(x) or outside the x^2 by 2/3:

   (2/3)•f(x)

2. translation left 5 units means "x+5" inside:

   (2/3) • f(x+5)

3. tranlate down 2 units means "-2" outside:

      (2/3) • f(x+5) -2

or    (2/3) (x+5)^2 - 2

[tex]\frac{2}{3}\cdot f(x+5)-2[/tex]   or   [tex]\frac{2}{3}\cdot (x+5)^2-2[/tex]

z [tex]\geq[/tex] 20

Step-by-step explanation:

we start with the inequality 11 ≤ z - 9​. Simplifying gives 20 ≤ z, so z [tex]\geq[/tex]  20

Answer:

The slope of f(x) is equal to the slope of g(x). The y-intercept of f(x) is greater than the y-intercept of g(x).

Step-by-step explanation:

F(x) is already given to you on the graph. You need to plot the x and g(x) graph. (remember g(x) is just a fancy way of saying y)

Once this line is plotted, you will see that f(x) and g(x) are parallel to one another. G(x) is below f(x), so its y-intercept is lower.

$6.83333333333 x 18 (weeks) = $123

Answer:

Step-by-step explanation:

18 weeks = 6 * 3

                = 6 * 20.5

                 = $ 123

Answer:

X = 7

Step-by-step explanation:

because of you do 5+2 = 7 then you minus 3 which you get 4.

the. if you have a production of around 10 you will get 7.

or you can do.

3+2 which is 5 and then you multiply that by 2 which is 10 and then you comprised that number therefore you will get 6 but you have to find X so we youndelie (think that's how u spell it) X which will equal to 1 and 6+1 is 7. once you get it it's quite simple

Answer:

any equation with a 6 before the x

y=6x+b

Step-by-step explanation:

standard form is y=mx+b

m is the slope and b is y-intercept

Answer:

y= 2x - 11

Step-by-step explanation:

(-7 +1 )/ (2-5) = 2

y= 2x +b

-1 = 2* 5 + b

solve for b and you get -11 so the equation of the line is :

y = 2x -11

Answer:

200<=15x

divide by 15

You have to work at least 13 1/3 hours to earn $200

<= means greater than or equal to

Step-by-step explanation:

The minimum number of hours to earn at least $200 is 14

Let the number of hours be x.

Given that hourly rate is $15, and he needs to earn at least $200;

The inequality of the scenario is:

15x >= 200

Divide both sides by 200

x >= 13.33

The smallest integer greater than 13.33 is 14.

So, we have:

x = 14

Hence, the minimum number of hours is 14

Step-by-step explanation:

Answer:

Perpendicular

Step-by-step explanation:

Both lines intersect and form a right angle when they intersected each other. Non co-planar means essentially means "on different planes", but both lines do lie on the same plane. Parallel lines don't intersect at all! However lines a and d are intersecting. Skewed means neither parallel nor perpendicular (meaning they intersect and don't form a right angle).

Answer:

It would be perpendicular.

Step-by-step explanation:

Perpendicular lines form a 90-degree angle.

Skew lines are on different planes and do not intersect.

Since A and D intersect with a 90-degree angle they're perpendicular.

The first step, u have add 10.1 + 2.7 = 12.8 .

Then, u add 12.8 - 12.6 = 00.2.

After that u add 10.1 + 2.7 + 12.6 + 22.9 = 48.3.

If u want u can also add 10.1 + 2.7 + 12.6 to show the total without the North Kailbab Trail added.

Answer:

3 : (1/2) =[tex]\frac{6}{1} =6[/tex]

Step-by-step explanation:

Divide: 3 : [tex]\frac{1}{2} =\frac{3}{1} *\frac{2}{1} =\frac{3 * 2}{1*1} =\frac{6}{1} =6[/tex]

Dividing two fractions is the same as multiplying the first fraction by the reciprocal value of the second fraction. The first sub-step is to find the reciprocal (reverse the numerator and denominator, reciprocal of [tex]\frac{1}{2}[/tex] is [tex]\frac{2}{1}[/tex]) of the second fraction. Next, multiply the two numerators. Then, multiply the two denominators.

In words - three divided by one half = six.

The inequality expression of the statement is |2s - 7| >= -1

Inequality expressions are mathematical statements that are represented by variables, coefficients and operators where the opposite sides are not equal

The mathematical statement is given as

|2s - 7| is bigger than or equal to -1

The term "bigger than or equal" means greater than or equal to

In mathematics, the term greater than or equal to is represented as >=

So, we have the representation of the mathematical statement to be

|2s - 7| >= -1

From the question, we are not instructed to simplify the expression

This means that we leave the expression |2s - 7| >= -1 unsimplified

Hence, the mathematical statement as an expression is |2s - 7| >= -1

Answer:

The last option: x > -2 and x < 5

Step-by-step explanation:

First of all we look at the circles at the end.

Both are open circles, which indicates that -2 and 5 are not included.

Reading left to right, x is greater than -2 (remember, not greater than or equal to)

And x is less than 5 (not including 5)

The compound inequality is x > -2 and x < 5
