Find the solution(s) of the system of equations:
y = –x2 + 4x + 5
y = x2 + 2x + 1

a. (–1,2) and (2,17)
b. (1,0) and (–2,9)
c. (1,4) and (2,9)
d. (–1,0) and (2,9)

Answers

The correct solution is D or (-1,0) and (2,9).

The easiest way to find the solutions is to graph the equations then observe the coordinate intersections of each graph :)

The solution to the equation are (2, 9) and (-1, 0)

Given the functions as shown below:

y = –x2 + 4x + 5 y = x2 + 2x + 1

Equating both equations will give;

–x^2 + 4x + 5 = x^2 + 2x + 1

Collect the like terms to have:

–x^2 + 4x + 5 –x^2 - 2x - 1 = 0

-2x^2 + 2x + 4= 0\

2x^2 - 2x - 4 = 0

x^2 - x - 2 =0

Factorize to have:

x^2 - x - 2 =0

x^2 - 2x + x - 2 = 0

x(x-2)+1(x-2) = 0

x = 2 and -1

If x = 2

y = 2^2 + 2(2) + 1

y = 9

If x = -1

y = (-1)^2 + 2(-1) + 1

y = 1 - 2 + 1

y = 0

Hence the solution to the equation are (2, 9) and (-1, 0)

please explain to me how to solve for x and y

Answers

Answer:

(x, y) = (6, 2)

Step-by-step explanation:

You solve for x and y by writing equations that reflect the relation applicable to the given geometry.

The diagonals of a parallelogram bisect each other. That means the halves of each diagonal are equal.

2x -4 = 4y . . . . . . down diagonal

x +4 = 7y -4 . . . . . up diagonal

We can subtract the first equation from 2 times the second equation to eliminate the x-variable.

2(x +4) -(2x -4) = 2(7y -4) -(4y)

2x +8 -2x +4 = 14y -8 -4y . . . . . . eliminate parentheses

12 = 10y -8 . . . . . . . . . . . . . . . . . collect terms

20 = 10y . . . . . . . . . . . . . . . . . . add 8

2 = y . . . . . . . . . . . . . . . . . . . . divide by 10

Substituting into the second equation gives ...

x +4 = 7(2) -4

x = 6 . . . . . . . . . . . . subtract 4

The values of x and y are (x, y) = (6, 2).

Many gas stations give a discount for paying with cash instead of a credit card. William’s local gas station gives a discount of $0.05 per gallon. He fills his car with 20 gallons of gas. How much will William save by paying cash instead of credit card?

Answers

0.05 x 20 = 1
William will be saving $1

The amount that William would save by paying cash instead of credit card is $1

What is a Discount?

This refers to the amount deducted from the value of a certain commodity so that there would be a reduced price for the good.

Hence, given that there is a discount of $0.05 per gallon if you pay with cash

William fills 20 gallons of gas

The amount saved by paying cash by William would be 0.05 * 20 = $1

JL= 44.5

JK=23.3

KL=23.3

Step-by-step explanation:

Since JK and KL are equal to eachother, we have to find the missing variable through them. You want to choose one side to have the variable number and the other side for the normal numbers. I can't really explain this next bit, so I'll show the math below:

V N

4x - 10.7 = 2x + 6.3

+10.7. +10.7

_________________

4x = 2x + 17

-2x -2x

2x = 17

So, once there is only one variable number and one normal number left, what do you do? You divide the variable by the number it's worth and carry the division to the normal number.

2x = 17

÷2. ÷2

_______

x = 8.5

So, 8.5 is our number we need. We then just insert it into all the equations to get the numbers.

4 × 8.5 = 34

34 - 10.7 = 23.3

Since JK and KL are equal, they are both 23.3.

5 × 8.5= 42.5

42.5 + 2 = 44.5

4x+ 6y^2

Step-by-step explanation:

A rock is thrown into a pool 72 inches deep. The rock sinks at a rate of 4 inches per
second (s). The rock's height (h) above the bottom of the pool is given by the
equation: h = 72 – 4s. After how many seconds will the rock be half way to the
bottom?

Answers

Half of 72 is 36. If you divided 36 by 4, you would get 9. So, s = 9 and means that it takes 9 seconds for the rock to be sunk half way.

b= -1/5

Step-by-step explanation:

Though a variable's sign changes when it is multiplied by -1, its absolute value does not. Therefore, we can eliminate the 1:

1/5+b=0

b+1-1/5=0-1/5

b+0/5= 0 -1/5

b=0 -1/5

and you have b= -1/5 as your answer
