Answer:

C.

Step-by-step explanation:

f(x) = 3x+2

f(x) = -4

-4 = 3x+2

-4-2 = 3x

-6 = 3x

-6/3 = x

-2 = x

x = -2

Speed = distance / time

Speed = 200 meters / 20 seconds

Speed = 10 meters / second

1 meter per second = 3.6 km per hour

10 meters per second x 3.6 = 36 km per hour

Answer: 36 kilometers per hour

Step-by-step explanation: Average speed = total distance / total time.

A and D

Answer:

(-[tex]\sqrt{10}[/tex]) and ([tex]\sqrt{10}[/tex]) are both solutions

Step-by-step explanation:

If you plug in (-[tex]\sqrt{10}[/tex]) for x, you get [tex](-\sqrt{10})^{2}[/tex] which is equal to 10

Also, when you plug in ([tex]\sqrt{10}[/tex]) for x, you get [tex](\sqrt{10} )^{2}[/tex] which is equal to 10

The correct answer is She have left $7.5 after buying the coat and skirt.

Step-by-step explanation

This question is incomplete, the complete question is:

Mary had $60 and spent 0.75 o 3/4 of it on a coat. She then bought a skirt with 50% of the money that she had left. How much money did she have left after buying the coat and skirt?

The answer is $7.50

Explanation:

To know how much money Mary has left after buying the coat we have to multiply $60 by 0.75 as this would help us know the price of the coat.

60 x 0.75 = 45 (price of the coat)

Then we have to subtract 45 from 60 to know how much money she have left after buying the coat.

60 -45 = 15 (Money left)

Then she bought a skirt with 50% of the money that she had left. To know how much money costs the skirt we have to multiply 15 by 0.50. The result of this operation is $7.5, and finally, we have to subtract again $7.5 that she spent on her skirt from $15 and the final result is $7.5

Answer:

f(x)=x+2

Step-by-step explanation:

Slope= (7-0)/(5-(-2)) = 7/7 = 1

Y-intercept= 2

substitute the slope, 1, for m and the y-intercept, 2, for b to get:

f(x)=x+2

hope this helps!

The linear function f with f(5)=7 and F(-2)=0 is f(x) = x + 2

f(5) = 7

This means when x = 5 , y = 7

(5, 7)

f(-2) = 0

(-2, 0)

This implies when x = -2 , y = 0

Using the linear function formula,

y = mx + b

where

m = slope

b = y-intercept

Therefore, the function can be represented as follows:

m = 0 - 7 / -2 - 5 = -7 / -7 = 1

Therefore,

y = x + b

0 = -2 + b

b = 2

The function in relation to x can be represented as follows:

f(x) = x + 2

Answer:

Choice A

Step-by-step explanation:

It's Choice A because it's the only one that kept the shaded area underneath the line, and the lines went up to only 48 hours for the first job and for the second job. Then all the possible solutions are in the shaded area.

The graph that best represents the solution set for all possible combinations that the college students could have worked is graph A.

The graph that would be best is one that has all possible hour as under 48 hours on both the y and x axis.

This ensures that whatever combinations are picked, the 48 hours constraint will still stand. Graph A is the only graph with this quality and so is the best one.

Answer:

Step-by-step explanation:

Answer:

A = $1,650.24

Step-by-step explanation:

A = P(1 + r/n)^nt

Where

A = future value

P = present value = $1,600

r = interest rate = 3.1% = 0.031

n = number of periods = 4

t = time = 1 year

A = P(1 + r/n)^nt

= 1,600( 1 + 0.031 / 4)^4*1

= 1600( 1 + 0.00775)^4

= 1600(1.00775)^4

= 1600(1.0314)

= 1,650.24

A = $1,650.24

The additive inverse would be -10.5

Henry runs up 10.5 flights of stairs. Then the additive inverse represents running down flights of stairs will be - 10.5.

The analysis of mathematical representations is algebra, and the handling of those symbols is logic.

PEMDAS rule means the Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This rule is used to solve the equation in a proper and correct manner.

The reverse number is a number's complementary inverse. When a number is multiplied by its additive inverse, the result is zero.

Answer:

Distance of L from AB = 0.6 in.

m∠ABC = 60°

Step-by-step explanation:

Given:

LB = 1.2 in

LC = 0.6 in

We have to find the distance of point L to AB or length of LD.

From right triangle ΔBCL,

Sin(∠LBC) = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]

                 = [tex]\frac{LC}{LB}[/tex]

                 = [tex]\frac{0.6}{1.2}[/tex]

                 = [tex]\frac{1}{2}[/tex]

m∠LBC = 30° [Since ∠LBC is an acute angle]

Since, ∠LBC ≅ ∠LBA

m∠LBA = 30°

Now from right triangle ΔLDC,

sin(∠LBA) = [tex]\frac{LD}{BL}[/tex]

sin(30)° = [tex]\frac{LD}{1.2}[/tex]

[tex]\frac{1}{2}=\frac{LD}{1.2}[/tex]

LD = 0.6

Therefore, Distance of point L from AB is 0.6 in.

m∠ABC = m∠ABL + m∠LBC

             = 30° + 30°

             = 60°

Answer:

10% of 60 = 6

25% of 60 = 15

50% of 60 = 30

20% of 60 = 12

Step-by-step explanation:

Answer:

10% = 6

25% = 15

50% = 30

20% = 12

Step-by-step explanation:

10 %  just drop the 0 from 60.    1/10 of 60 is 6

25% is 1/4.  Divide: 60/4 =15

50% is half.  Divide 60/2 = 30

20% is 1/5   Divide 60/5 =12

Answer:

4/5 (or 8/10)

Step-by-step explanation:

the least common denominator of 2 and 10 is 10, so you have to multiply the first fraction (1/2) by 5/5 so that the denominator of that fraction will become 10. Since 3/10 already has 10 as the denominator, you leave it. By adding 5/10 and 3/10 together you'll get 8/10.  

If the question asks to simplify your answer, divide the numerator and denominator of 8/10 to get 4/5

Answer:

14.6328% , $5836.03

Step-by-step explanation:

Here we are going to use the formula

= 39000

r=?

= 11000

n=8

Hence

Hence r= 0.1463

In percentage form r = 14.63%

Now let us see calculate the value of car in 2003 that is after 12 years

we use the main formula again

= 39000

r=0.1463

= ?

n=12

Hence the car's value will be depreciated to $5840.34 (approx) by 2003.
