Answer:

f(2) = 9

g(1) = -3

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS

Algebra I

Step-by-step explanation:

Step 1: Define

f(x) = 4x + 1

g(x) = x² - 4

f(2) is x= 2

g(1) is x = 1

Step 2: Evaluate

f(2)

g(1)

Answer:

1=(4/4)*(4/4)

2=(4/4)+(4/4)

3 = (4+4+4)/4

4 = 4 + (4-4)*4

20=4 × (4/4 + 4)

20=4 × (4/4 - (-4))

[tex]20 = \sqrt{4} +\sqrt{4} + (4x4)[/tex]

[tex]20 = \sqrt{4} +\sqrt{4} + (-4 x -4)[/tex]

Step-by-step explanation:

The x is a multiplication sign not a variable, I hope this right.  Good luck, I am so tired.

Answer:

Step-by-step explanation:

[tex]\bold{slope\, (m)=\dfrac{change\ in\ Y}{change\ in\ X}=\dfrac{y_2-y_1}{x_2-x_1}}[/tex]

(−4, 2)    ⇒     x₁ = −4,  y₁ = 2

(6,−3)     ⇒     x₂ = 6,  y₂ = −3

So the slope:

[tex]\bold{m=\dfrac{-3-2}{6+4}=\dfrac{-5}{10}=-0.5}[/tex]

The point-slope form of the equation of the line passing through point (x₀,y₀) and with slope m is:  y - y₀ = m(x - x₀)

m = -0.5

(−4, 2)    ⇒     x₀ = −4,  y₀ = 2

Therefore:

               y - 2 = -0.5(x - (-4))

               y - 2 = -0.5x - 2               {add 2 to both sides}

               y = -0.5x          ←  the slope-intercept form of the equation (b=0)

Answer:

Harper is 200 yards away from her home if the map shows 3 inches

Step-by-step explanation:

50 yards = 3/4 inch

3 inches = 3/1

3/1 x 4/4 = 12/4

12/4 = 3 inches

50 x 4 = 200

I hope this helped and if it did I would appreciate it if you marked me Brainliest. Thank you and have a nice day!

Answer:

$22.50

Step-by-step explanation:

First, we find how much we need to take off so our equation is:

30 x 0.25 = 7.5

So, we take 7.5 off of 30 which is:

30 - 7.5 = 22.5

So, the shirt is selling for $22.50

Hope this helps:)

Answer:

l

Step-by-step explanation:

Hey there!

“-1/5x ≤ 8”

MULTIPLY both sides by -5

-1/5x × -5 ≤ 8 × 5

CANCEL out: -1/5 × -5 because that gives you 1

KEEP: 8 × 5 because that helps us solve for your given equation

NEW EQUATION: x ≥ 8 × 5

8 × 5 = 40

Answer: x ≥ 40

It is a CLOSED circle SHADED to the RIGHT

Answer:

i think it would be 25

Step-by-step explanation:

cause, 400÷ 80+ 20 is 25

but i might be wrong

Answer:

50 : 25 = 75 : 37.50

Step-by-step explanation:

If 50 apples cost $25, that means 2 apples cost $1.

75 apples cost 37.5, or $37.50

Answer:

(x, y) represent coordinates, m represents slope, and b represents the y-intercept

Answer:

= -8

Step-by-step explanation:

plug in 3 for b

10 - 2 (3)^2

10 -2 (9)

10 - 18

-8

Answer: -8

Step-by-step explanation: just substitute the 3 in for b

Step-by-step explanation:

Base of smaller pink triangle

= (3m + 6m) - 7m = 2m.

Area of smaller pink triangle

= 0.5(2m)(5m) = 5m².

Area of bigger pink triangle

= 0.5(6m)(5m) = 15m².

Hence total area shaded = 5m² + 15m² = 20m².

Answer:

B and C are the correct options

Step-by-step explanation:

The parent function here will be ;

f(x) = x^4

Multiplying x^4 by 2 means that we are having a vertical stretching

What this means is that the leading coefficient 2 stretches the graph vertically by 2 units

Subtracting -3 means that we are translating the graph down by a value of 3 units

So the correct options are;

B and C

Answer:

97 words in 1 minute

Step-by-step explanation:

A unit measure is so many somethings done usually per unit time. Examples

3 crackers and 1 apple is not. For ever apple, she ate 3 crackers would be

1 cookie is not. It is not per anything.

Driving 16 miles is not. Again, it is not per anything.

The answer is 97 words in 1 minute.

Answer:

$5

Step-by-step explanation:

The opposite of multiplication is division.

$15/Raking = 3 times more pay than mowing the lawn.

Divide $15/Raking by 3 and you'll get the pay for mowing the lawn.

15/3 = 5

Answer:

5

Step-by-step explanation:

Answer:

5300.

If you're rounding to the nearest hundred you look at the tens place. If its 5 or over you go up. So in this case we'll raise the 2 to a 5 because 6 is above 5.

Answer: 0.51

Step-by-step explanation:

We know that:

For a random selection, we have a probability of 0.42 where the house has both services and a probability of 0.82 that the house has only internet service.

Let's suppose that the percentage of houses the houses with internet service (the 82% of the total) that also have a home phone is X

Then we must have that, (X/100%) times the 0.82, must be equal to 0.42

(X/100%)*0.82 = 0.42

X = (0.42/0.82)*100% = 51%

This means that 51% of the houses with internet service, also have a home phone.

Then the probability that a house has a home phone given that it has internet service, is equal to:

51%/100% = 0.51

The probability is 0.51

Answer:

150 cm

Step-by-step explanation:

45/3  * 10 = 15 * 10 =150

check: 150 * 0.3 = 45

           150 * 0.7 = 105

105+45 = 150

uhm..

what expressions?

Answer:

$27.60

Step-by-step explanation:

First, we need to find how much the tip is:

we can convert 15% directly to a decimal:

15% = 0.15  

Then we find :

15% of 24 = 0.15 x 24 = 3.59999999999999

3.599999999999999 to the nearest cent is 3.60

Then we add the tip to the original bill:

3.60 + 24 = 27.60

So the total cost of the lunch is $27.60

Answer: 30 + 10.50h

Step-by-step explanation:

From the question, we are informed that Pat earns $30.00 for traveling to the homes plus $10.50 for each hour of tutoring.

The linear equation that models their total earnings for traveling and tutoring for a given number of hours would be written as:

= $30 + $10.50h

where h represents the number of hours for tutoring used.

For example, if 2 hours if tutoring was used, the total amount earned would be:

= 30 + 10.50h

= 30 + 10.50(2)

= 30 + 21

= $51
