Find the x-intercepts for the parabola defined

1 answer:

ArbitrLikvidat [17]3 years ago

7 0

Answer:

(-3,0) (1,0)

Step-by-step explanation:

y=2x^2+ 4x - 6

Factor out the greatest common factor

y = 2( x^2 +2x -3)

Factor inside the parentheses

y = 2( x+3)(x-1)

Setting the equation equal to zero to find the x intercepts

0 = 2( x+3)(x-1)

Using the zero product property

x+3 = 0 x-1 =0

x = -3 x = 1

The x intercepts are

(-3,0) (1,0)

What is the distance between (-6,4) and (-8,6)? Choose 1 answer:

lukranit [14]

Answer:

D

Step-by-step explanation:

We want to find the distance between (-6, 4) and (-8, 6).

We can use the distance formula given by:

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2$

Let (-6, 4) be (x₁, y₁) and let (-8, 6) be (x₂, y₂).

Substitute:

$d=\sqrt{(-8-(-6))^2+(6-4)^2$

Evaluate:

$d=\sqrt{(-2)^2+(2)^2$

Evaluate:

$d=\sqrt{4+4}=\sqrt{8}$

Hence, our answer is D.

What is an equation of the line that passes through the points (0, -1)(0,−1) and (6, 1)(6,1)?

horrorfan [7]

$slope = y2 - y1 \div x2 - x1$

$1 - - 1 \div 6 - 0$

$2 \div 6$

$1 \div 3$

$y = mx + c$

$1 = 1 \div 3 \times 6 + c$

$1 = 2 + c$

$c = 3$

$y = 1 \div 3x + 3$

a farmer sold 2/5 of his cows and another 10th was stolen he then gave 20% of the cows that was left what percentage of the cows

igor_vitrenko [27]

Answer:

4/5 of the cattle is left

Step-by-step explanation:

Given,

A farmer sells 2/5 of his cattle

Let "x" be the total number of cattle

Then,

sold = 2 / 5 x

Then,

Remaining = x - 2x / 5

remaining = 3x / 5

He gives 1/3 of the remainder to his son

son = 1 / 3 × 3x / 5

son = x / 5

Then,

Remaining = 3x / 5 - x / 5

Remaining = 4x / 5

Hope this answer helps you :)

Have a great day

Mark brainliest

Thus 4/5 of the cattle is left
