The equations y = x² - 2x + 1 and 2x - y = 2 intersect at the points (1, 0) and (3, 4)

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more numbers and variables.

Given that the quadratic function intersecting a linear function at points (1, 0) and (3, 4)

This means that this points lie on both functions.

y = x² - 2x + 1 and 2x - y = 2

For point (1, 0):

y = 1² - 2(1) + 1 = 0; 2(1) - 0 = 2

For point (3, 4):

y = 3² - 2(3) + 1 = 4; 2(3) - 4 = 2

The equations y = x² - 2x + 1 and 2x - y = 2 intersect at the points (1, 0) and (3, 4)

y = ax² + c thru (-1,4) and (0,8)

Substituting in the coordinates of each point for x and y gives two equations:

4 = a  (-1)² + c

8 = a (0²) + c = c

From the second one we see c=8.  Substituting into the first one,

4= a + 8

a = 4-8 = -4

Answer: a=-4, c=8

Check:

f(x) = -4x² + 8

f(0) = 8, good

f(-1) = -4(1) + 8 = 4, good

May I get some help? Thank you!​
Katen [24]

Answer:

vol. of triangular prism = lbh/2

vol. of rectangular prism = 18 of vol. of triangular prism

18x = 18 + 14x

4x = 18

x=4.5 ft

so vol. of rectangular prism = 6 × 4 . 5 × 3 = 81 ftcube

There were 90 runners just start a race in the first half of the race 1/3 of them dropped out in the second half of the race 1/5
Eva8 [605]

Answer:

6 runners finished the race

Step-by-step explanation:

it starts with 90 runners. then 1/3 of them dropped out in the second half of the race, that means you do 90 divided by 3

90 ÷ 3 = 30

Then, 1/5 of the runners remained.

That means you do 30 divided by 5

30÷ 5= 6

so the answer is 6 remaining runners finished the race.

I think of a number, double it and add eleven. I get twenty five. Using the statement above form an equation using the letter x!
Wittaler [7]

Answer:

2x + 11 = 25

x = 7

Step-by-step explanation:

Let the number be x.

Double of x and add 11 equals 25.

2x + 11 = 25

Solve the equation.

2x + 11 = 25

Subtract 11 on both sides.

2x = 25 - 11

2x = 14

Divide 2 on both sides.

x = 14/2

x = 7
