Find the equation of a line parallel to y - 5x = 10 that passes through the point (5,1)
xenn [34]

Answer:

y=5x-24

Step-by-step explanation:

First step find the slope of y-5x =10

Add 5x on the right side

y=10+5x

Slope is 5

Second step plug in (5,1)into point slope form:

y-y₁=m(x-x₁)

M is 5 cause thats slope

y-1=5(x-5)

distrubte 5

y-1=5x-25

add 1

y=5x-24

Y = 3(x-2)^2 + 5
Orlov [11]

The y-intercept coordinate is at the point (0, 17)

<h3>Properties of functions</h3>

Given the following function expressed as:

y = 3(x-2)^2 + 5

  • The vertex of the function (h, k) is (2, 5) while the axis of symmetry is at x = 2
  • Domain are the input values for which the function exist. According to the function, the domain and  range exists on all real values

The x-intercept is the point where y = 0

3(x-2)^2 + 5=0\\3(x-2)^2  = -5\\(x-2)^2 = -5/3\\x - 2 = 25/9\\x = 25/9 + 2\\x = \frac{43}{9}

Hence the x-intercept is (43/9, 0)

The y-intercept is the point where x = 0

y=3(x-2)^2 + 5\\y=3(-2)^2 + 5\\y=12+5\\y=17

The y-intercept coordinate is at the point (0, 17)

Solve the equation: 5 + 2(3 + 2x) = x + 3(x + 1)
Ann [662]

Answer:

No solutions

Step-by-step explanation:

In this question, you would be solving for x.

Solve:

5 + 2(3 + 2x) = x + 3(x + 1)

Use the distributive property.

5 + 6 + 4x = x + 3x + 3

Combine like terms.

11 + 4x = 4x + 3

Subtract 4x from both sides.

11 = 3

Since we don't have an "x value", there are no solutions.

"No solutions" would be your answer.
