how to Evaluate the expression, given functions f and g: f(x) = 3x - 2, g(x) = 7 – x^2. 3f(1) – 2g(-2)​

Step-by-step explanation:

divide 80 by for answer. number feet oer minute

Answer:

Sub the values for x and y into the equations.

Step-by-step explanation:

x = 2

y = 1

Y = 2x - 3

1 = 2(2) - 3

1 = 4 - 3

1 = 1

Y = -½x + 2

1 = -½(2) + 2

1 = - 1 + 2

1 = 1

Answer:

4   2/3

Step-by-step explanation: the four is on the side and 2 is over 3

Answer:

4 and 2/3

Step-by-step explanation:

3/3= 1 whole

14/3 - 3/3 =11/3 - 3/3= 8/3 - 3/3= 5/3 - 3/3= 2/3

No more 3/3, or 1 whole, can be subtracted, so you add the number of 3/3, or 1 whole, that you subtracted, which adds up to 4 wholes, and then you add the 2/3, which would equal 4 and 2/3.

Answer:

a. A = 111 tons

b. B = 85 tons.

Step-by-step explanation:

Let the weight of the heavier train be A.

Let the weight of the other train be B.

Translating the word problem into an algebraic equation, we have;

A + B = 196 tons .......equation 1

A - B = 26 .......equation 2

A = 26 + B .........equation 3

Substituting eqn 3 into eqn 1, we have;

26 + B + B = 196

2B = 196 - 26

2B = 170

B = 85 tons.

To find A, using eqn 3;

A = 26 + B

A = 26 + 85

A = 111 tons

Answer:

60 degrees

Step-by-step explanation:

all angles of an equilateral triangle are 60 degrees

Answer:

x=60

Step-by-step explanation:

We know that since all sides are the same, all angles are the same.

x=angle

(180) is the amount of degrees when you add up all of the angles in the triangle

3x=180

x=60

Step-by-step explanation:

Aviara Oaks Middle School:

Total student = 400

Boys : girls = 2:3

Boys = 2x , girls = 3x

2x + 3x = 400

       5x = 400

         x = 400/5

         x = 80

Number of boys = 2x = 2*80 = 160

Number of girls = 3x = 3 *80 = 240

VMS:

Total student = 360

Boys :  girls = 3 : 5

Number of boys = 3x

Number of girls = 5x

3x + 5x = 360

       8x = 360

        x = 360/8

       x =  45

Number of boys= 3x = 3 *45 = 135

Number of girls = 5x = 5 * 45 = 225

AOMS school has more boys attending their school.

Ratio of girls attending Aviara Oaks Middle School to girls attending Valley Middle School = 240 : 225

                                    = 48 : 45

Answer:

The equation of the perpendicular line is 2x-4y -12=0

Step-by-step explanation:

Explanation

Given that the equation of the line is 4x+2y-12=0

The equation of the perpendicular line b x -ay +k=0

The equation of the perpendicular line  2x -4y +k=0

This line passes through the point (8,1)

                           2(8)-4(1)+k=0

                      ⇒ 16 -4+k=0

                    ⇒   12 +k=0

                           k =-12

The equation of the perpendicular line is 2x-4y -12=0

Answer:

The maintained speed while hiking= 3 miles per hour

Let t be the time which represent the independent variable.

Also we know that  Distance= Speed × Time

⇒ Distance traveled while hiking=3 ×t=3t

Let h represent the distance function in miles, and h(t) the dependent variable.

Then h(t)=3t

When we put t=4

Then h(4)=3×4 =12 miles.

Answer:

the answer is 30.75 or 30 1/4

Step-by-step explanation:

8 can't go into 2 so 8 will go into 24

8 can go into 24 3 times thats our first digit

then multiply 8 times 3 you will get 24 write that under 24

then subtract 24 from the original 24 you will get 0

bring down the 6 to where the 0 is try to divide 8 into three

because you can't u will add a 0 next to the three

that is how you get the 30

thats as much as I know sorry I used the calculator

Step-by-step explanation:

Given

6x^4 - 30x³ - 84x²

= 6x² ( x² - 5x - 14 )

= 6x² ( x² - ( 7 - 2 ) x - 14 )

= 6x² ( x² - 7x + 2x - 14 )

= 6x² {x(x - 7) + 2 ( x - 7)}

= 6x² ( x - 7) (x +2 )

Hope it will help :)

Answer: 6x² ( x - 7) (x +2 )

Answer:

As she ate 1/10 of cake, we need to know how many cake remains after it, so we can substract:

1 - 1/10 = 10/10 - 1/10 = 9/10

Then, we need to divide the 9/10 into 3 portions:

(9/10) / 3 = 9/30 = 3/10

So we know the fractions would be 3/10 each on this situation..
