Solve the equation for y6x+y=5

What is the solution of the system of equations below?2x + 3y = 7
x + y = 3
(1) (1,2)
(2) (2,1)
(3) (4,-1)
(4) (4,1)

Answers

\begin{cases}2x + 3y = 7 \n x + y = 3 \ \ / *(-2) \end{cases}\n \n\begin{cases}2x + 3y = 7 \n -2x - 2y = -6\end{cases}\n+ \ ------- \ny=1\n \n2x + 3\cdot1 = 7

2x+3=7 \ \ |-3\n \n 2x+3-3=7-3\n \n2x=4 \ \ /:2 \n \nx=2 \n \n \begin{cases} x=2 \n y=1 \end{cases}
2x + 3y = 7
x + y = 3

x = 3 - y

substituting for x,

2(3 - y)  + 3y = 7

= 6 - 2y + 3y = 7
6 + y = 7

thus, y = 1

x = 3 - y

= 3 - 1
= 2.

Thus, x = 2 , y = 1

Thus, (2) is correct.

Find the value or values of x in the quadratic equation x2=6x-9.

Answers

Hi Harris


x²=6x-9

First thing we need to do is

subtract 6x-9 from the booth sides

x²-(6x-9)=6x-9-(6x-9)

x²-6x+9=0

Now we gonna factor the left side

(x-3)(x-3)=0

Set factor equal 0

x-3=0 or x-3=0

x=3


I hope that's help !

x² = 6x - 9, or x² - 6x + 9 = 0, or x² - 2*x*3 + 3² = 0, or (x-3)² = 0 => x₁ = x₂ = 3.

It takes a biker 1/2 hours to ride 8/3 miles. What is the biker's rate,in miles per hour?

Answers

Answer:

The biker is traveling at 5(1)/(3) miles per hour.

Step-by-step explanation:

To find the rate, in miles per hour, you must use the formula r = d/t.

(r = rate)

(d = distance)

(t = time)

(8)/(3) ÷ (1)/(2) = 5(1)/(3)

During her first year of college, Sara put $2000 in the bank to save for a trip to Italy after graduation. The money earned 3% simple annual interest. After 4 years, how much money did she have in the bank for her trip?

Answers

Answer:

2,240

Step-by-step explanation:

Sara will have US$ 2,251.02 in the bank after 4 years for her trip to Italy.

Step-by-step explanation:

1. Let's review the data given to us for solving the question:

Investment of Sara during her 1st year of college = US$ 2,000

Duration of the investment = 4 years

Annual interest rate = 3%

2. Let's find the future value of this investment after 4 years, using the following formula:

FV = PV * (1 + r) ⁿ

PV = Investment of Sara during her 1st year of college = US$ 2,000

number of periods (n) = 4

rate (r) = 3% = 0.03

Replacing with the real values, we have:

FV = 2,000 * (1 + 0.03) ⁴

FV = 2,000 * (1.03) ⁴

FV = 2,000 * 1.12550881

FV = 2,251.02

Sara will have US$ 2,251.02 in the bank after 4 years for her trip to Italy. Later you round the answer and that gives you 2,240

If 75% is 60, what is the full cost?

Answers

If 75% is 60 then:
0.75x=60
Solve for x by dividing both sides by 0.75:
(0.75x)/(0.75)=(60)/(0.75)
x=80
The answer would be 80
