Answer:

f(4) = -6, g(-3) = 36

Step-by-step explanation:

To find f(#) or g(#), plug the number into each x of the equation.

f(x) = -2x + 2

f(4) = -2(4) + 2

Simplify the parentheses by multiplying.

f(4) = -8 + 2

Add.

f(4) = -6

g(x) = 3x² - 3x

g(-3) = 3(-3)² - 3(-3)

Simplify the exponent first.

g(-3) = 3(9) - 3(-3)

Simplify the parentheses by multiplying.

g(-3) = 27 + 9

Add.

g(-3) = 36

Answer:

(8,23)

Step-by-step explanation:

x+y=31

4.5x + 11y = 289

x = 31 -y

4.5(31 - y) + 11y = 289

139.5 - 4.5y + 11y = 289

6.5y = 149.5

y = 23

x = 31 - 23 = 8

The ordered pair, (x, y) = (8, 23).

An ordered pair exists as a composition of the x coordinate (abscissa) and the y coordinate (ordinate), containing two values noted in a fixed order within parentheses.

Given: A taxi driver had 31 fares to and from the airport last Monday. The price for a ride to the airport exists $4.50, and the price for a ride from the airport exists $11. The driver collected a total of $289 for the day.

x + y = 31........(1)

4.5x + 11y = 289 ........(2)

From (1), we get

x + y = 31

x = 31 - y

Substitute the value of x in (2), and we get

4.5x + 11y = 289

4.5(31 - y) + 11y = 289

Simplifying the above equation, we get

139.5 - 4.5y + 11y = 289

6.5y = 149.5

y = 23

substitute the value of y, in (1) then we get

x = 31 - y

x = 31 - 23 = 8

The value of x = 8 and y = 23.

Therefore, the ordered pair, (x, y) = (8, 23).

Answer:

41,  -7,  18

Step-by-step explanation:

Let a = smallest number

b = second number

c = largest number

Then  a + b +c = 52       c - a = 48        a + b = 11

11 + c = 52

c = 41       41 - a = 48

                      -a = 6

                       a = -7                         -7 + b = 11

                                                                b = 18

Answer:

a=-7

b=18

c=41

Step-by-step explanation:

a+b+c=52

c-a=48

a+b=11

11+48=59

a+59=52

a=-7

Answer:

In Odette's solution, 7 is the number of

nickels and 8 is the number of dimes

Answer:

2 weeks

Step-by-step explanation:

y = mx + b

y = total number of chapters read = [tex]9\frac{2}{3}[/tex]

m = number of chapters read per week = [tex]4\frac{5}{6}[/tex]

x = number of weeks = what we're solving for

b is not needed to find this solution

[tex]9\frac{2}{3}[/tex] = [tex]4\frac{5}{6}[/tex] x                            divide [tex]4\frac{5}{6}[/tex] from both sides

x = 2 weeks

Answer:

  15

Step-by-step explanation:

In vector form, the equation of point p on the line can be written as ...

  p = (-3, -4) +t(25 -(-3), 38 -(-4)) . . . . . for some scalar t

  p = (-3, -4) +t(28, 42)

  p = (-3, -4) +14t(2, 3)

where t takes on any value between 0 and 1.

If we let t = n/14 for some integer 0 ≤ n ≤ 14, then the coordinates of point p will be integers.

There are 15 values that n can have in the allowed range.

The caterpillar touches 15 points with integer coordinates.

Answer:

[tex]\sqrt{21}[/tex]

Step-by-step explanation:

Use the pythagorean theoreom, a^2+b^2=c^2.

We know the hypontenuse and one of the sdes

a^2+2^2=5^2

a^2+4=25

subract four from both sides to isolate variable

a^2=21

square root both sides and you have the answer of sq root 21!

Answer:

5x²

-1/2( x+8)

Step-by-step explanation:

The dominant term is 2x^2 *x or 2x^3

We want to know what happens when x goes to negative ∞

2 ( -∞) ^3 → 2 * (-∞) → -∞

As long as we multiply by a positive number, we will still be approaching negative infinity ( or decreasing)

-3  is negative

.2x is negative when x approaches negative infinity

.5 x^2 = .5( -∞)^2 = 5 ( ∞) = ∞ which is positive

-1/2 x is the dominant term  = -1/2(- ∞) =   ∞ which is positive

4(2x) is the dominant term  = 8(- ∞) = - ∞ which is negative

[tex]\displaystyle 5x^2\text{ and } -\frac{1}{2}(x+8)[/tex]

Step-by-step explanation:

We are given the function:

[tex]f(x)=(2x^2+5)(x-7)[/tex]

And we want to determine the factor(s) that we can multiply to the above function that will cause the graph of f to decrease as x approaches negative infinity.

We can see that the dominant term will be:

[tex]2x^2(x)=2x^3[/tex]

Thus:

[tex]2(-\infty)^3\Rightarrow -\infty[/tex]

It is already decreasing (shifting towards negative infinity) as x approaches negative infinity.

In order to preserve this, then, the factors must be positive as x approaches negative infinity.

The first factor is -3.

-3 is always negative, so it will make f increase.

The second factor is [tex]0.2x[/tex].

[tex]0.2(-\infty)\Rightarrow -\infty[/tex]

This will also make f increase.

The third factor is:

[tex]5(\infty)^2\Rightarrow \infty[/tex]

This is positive, so it will allow f to remain decreasing as x approaches negative infinity.

The fourth factor is:

[tex]\displaystyle -\frac{1}{2}(-\infty+8)\Rightarrow -\frac{1}{2}(-\infty)\Rightarrow \infty[/tex]

This is also positive, so it will also allow f to remain decreasing.

Lastly, the fifth factor is:

[tex]4(2(-\infty)-7)\Rightarrow 4(-\infty)\Rightarrow -\infty[/tex]

This is negative, so it will make f increasing.

Therefore, our answers are the third and fourth choices.

The function is increasing from (–∞, 0). Then the correct option is A.

If the value of y increases as the value of x increases, then increasing function.

And if the value of y decreases as the value of x increases, then decreasing function.

From the graph, the function is increasing from (–∞, 0).

Then the correct option is A.

Step-by-step explanation:

Answer:

2√5

Step-by-step explanation:

By applying Pythagoras (hypotenuse)^2=(Base)^2 +(Height)^2

The length of the ramp is approximately 4.47 feet.

Pythagoras's theorem states that in a right-angled triangle, the square of one side is equal to the sum of the squares of the other two sides.

If the base of the ramp is 4 feet and the vertical height is 2 feet, we can use the Pythagorean theorem to find the length of the ramp:

ramp length² = base² + height²

ramp length² = 4² + 2²

ramp length² = 16 + 4

ramp length² = 20

Taking the square root of both sides, we get:

ramp length = √20

Simplifying the square root of 20, we get:

ramp length ≈ 4.47 feet

Therefore, the length of the ramp is approximately 4.47 feet.

Answer:

64 degrees

Step-by-step explanation:

All angles in a triangle plus each other equals 180. First find the missing angle of the triangle with 2 given angles. The missing angle is 64 degrees because 68 plus 48 is 116 and 180 - 116 is 64. Vertical angles are always congruent and the missing angle is vertical to the missing angle on the first triangle.

Answer:

  5 mph, 11 mph

Step-by-step explanation:

Together, they cover 24 miles in 1.5 hours, so their total rate of speed is ...

  (24 mi)/(1.5 h) = 16 mi/h

If s is the rate of the slower jogger, then s+6 is the rate of the faster one. Their total speed is ...

  s + (s+6) = 16

  2s = 10 . . . . . . . subtract 6

  s = 5 . . . . . . . . . divide by 2

  s+6 = 11

The rates of the joggers are 5 mph and 11 mph.
