Answer:

y - 4= -2(x - 2)

Step-by-step explanation:

(This answer is in point slope form, if you need the answer in a different form like slope intercept, you would have to distribute the negative 2 and bring the negative 4 to the right side.)

So, you know the line is parallel to the equation y= -2x + 10. We know that parallel lines must have the same slope, so the answer will have a slope of negative 2. Because they have given you a point that the line passes through, we are going to put the answer in point slope form. we know a point and we know the slope, hence it is called point-slope.

Point slope form is y - y₁ = m(x - x₁). The m stands for the slope, and the x₁ and y₁ is where you will plug in the x and y coordinates (2,4) .

So to plug in the numbers into point slope form it would be y - 4 = -2 (x - 2). hope this helped :)

Answer:

Before, he had 21 baseball cards and 12 football cards.

we know that:

21 = 7*3

12 = 4*3.

He decided to pack the cards in groups of 3, because 3 is the only common factor between 21 and 12.

Now, if he decides to keep one baseball card, now he has:

20 baseball cards and 12 football cards.

Now he has two possibilities for how many cards are in each pack, this is because:

12 = 4*3 = 2*2*3

20 = 4*5 = 2*2*5

12 and 20 have two common factors, 4 and 2.

a) Then he can sell them in packets of 2 cards each with:

12/2 = 6 packs of football.

20/2 = 10 packs of baseball.

b) Or he can sell them in packets of 4 cards each with:

12/4 = 3 packs of football.

20/4 = 5 packs of baseball.

Answer:

Cost of the trip = $132.69

Step-by-step explanation:

Given:

Total distance = 750 mile

Fixed charge = $20.19

Variable charges = $0.15 per mile

Find:

Cost of the trip

Computation:

Y = $0.15x + $20.19

Y = $0.15(750) + $20.19

Y = $132.69

Cost of the trip = $132.69

Answer:

5/6 and 6/7

Step-by-step explanation:

Answer:

5/6 then 6/7

Step-by-step explanation:

Both the numerator and denominator are being increased by 1.

The top (numerator) is one less than the denominator in each term.

So  the answers are 5/6 and then 6/7.

Answer:

X

Step-by-step explanation:

X+y=X so the answers x

The value of x using the two rectangles is 8.

We have,

Rectangle A:

Area

= length x width

= 6 x 4

=24 cm²

Rectangle B:

Area

= length x width

= 3x cm²

Now,

The area of both triangles is the same.

This means,

Area of first rectangle = Area of the second rectangle

24 = 3x

x = 24/3

x = 8

Thus,

The value of x using the two rectangles is 8.

Answer:

The team makes $37,250

Step-by-step explanation:

Answer:

The answer is below

Step-by-step explanation:

The bottom of a river makes a V-shape that can be modeled with the absolute value function, d(h) = ⅕ ⎜h − 240⎟ − 48, where d is the depth of the river bottom (in feet) and h is the horizontal distance to the left-hand shore (in feet). A ship risks running aground if the bottom of its keel (its lowest point under the water) reaches down to the river bottom. Suppose you are the harbormaster and you want to place buoys where the river bottom is 20 feet below the surface. Complete the absolute value equation to find the horizontal distance from the left shore at which the buoys should be placed

Answer:

To solve the problem, the depth of the water would be equated to the position of the river bottom.

[tex]d(h)=river \ bottom\\\\The \ river \ bottom=-20\ feet(below)\\\\d(h) = -20\\\\\frac{1}{5}|h-240|-48=-20\\ \\\frac{1}{5}|h-240|=-20+48\\\\\frac{1}{5}|h-240|=28\\\\|h-240|=28*5\\\\|h-240|=140\\\\h-240=140\ or\ h-240=-140\\\\h=140+240\ or\ h=-140+240\\\\h=380\ or\ h=100\\\\The\ buoys\ should\ be\ placed\ at\ 100\ feet\ and\ 380\ feet\ from\ left-hand\ shore[/tex]

Answer:

Katherine will receive $23214 to the nearest dollar from both investments.

Step-by-step explanation:

Simple interest = Principal × Time × rate

Le's work out the interest Katherine earns from the two investments.

Money Market Account

Simple interest = 7770 × 5.8/100 × 6/12

= 7770 × 0.058 × 0.5 =  $225.33

So, the amount she gets at maturity is:

$7770 + $225.33= $7995.33

CD account

Simple interest = 12500 × 0.0725 × 3 = $2718.75

The amount she receives at the end of period is:

$12500 + $2718.75 = $15218.75

The total amount she receives from both investments at maturity is:

$15218.75 + $7995.33 = $23214.08

This to the nearest dollar is:

= $23214

Answer:

a) 30feet

b) 9.12feet

Step-by-step explanation:

a) Given the path of the ball is modeled by the equation y=-0.02(x-18)²+12​, where;

x is the​ ball's horizontal distance in feet from​ Amaya's position

y is the distance in feet from the ground to the ball.

The ball will be at the maximum height when dy/dx = 0

Differentiate the function:

dy/dx = 2(-0.02)(x-18)^(2-1)+0

dy/dx = -0.04(x-18)

Equate the resulting expression to zero and find x as shown;

-0.04(x-18) = 0

Open the parentheses

-0.04x+0.04(18) = 0

-0.04x+0.72 =0

-0.04x = -0.72

x = -0.72/-0.04

x = 18ft

Hence the ball is 18ft away from Amaya when it is at its maximum height

b) To get the balls height y when x = 30, we will substitute x = 30 into the equation given and calculate the value of y as shown:

y=-0.02(x-18)²+12

y = -0.02(30-18)²+12

y= -0.02(12)²+12

y = -0.02(144)+12

y = -2.88+12

y = 9.12 feet

Hence the Ball's height is 9.12feet when it crosses the net at x = 30.
