Answer 1

Answer:

D: x = 5/ 2 + h

Step-by-step explanation:

-hx + 4 = 2x -1

First step: get the x's to one side and the integers to the other side.

-hx - 2x = -5

Second step: Take out a factor of x

x(-h - 2) = -5

Third step: seperate x from the rest of the equation by dividing

x = -5/-h - 2

Fourth step: take out that -1 from both numerator and denominator, cancelling the -1's out.

x = 5/h+2

Write a Linear Equation in
Point-Slope Form.
m = -5
(-3, – 7)

Answers

Answer: y + 7 = -5(x + 3)

==================================

Work Shown:

m = -5 is the slope

(x1,y1) = (-3,-7) is the point the line goes through

Plug this into the point slope form below and simplify.

y - y1 = m(x - x1)

y - (-7) = -5(x - (-3))

y + 7 = -5(x + 3)

Side note: If we solved for y, we'd get y = -5x - 22 showing that -22 is the y intercept.

Find the equation of a line that contains the points (4,−1) and (−1,−4). Write the equation in slope-intercept form, using fractions when required.

Answers

Answer:

y = 3/5x - 17/5

Step-by-step explanation:

slope formula: (y₂ - y₁) / (x₂ - x₁)

First, plug in these values of the two given points.

(-4 - (-1)) / (-1 - 4)

Simplify within the parentheses.

(-4 + 1) / (-1 - 4)

(-3) / (-5)

3/5

This is your slope. Plug this into a standard slope-intercept equation: y = mx + b

To find b, we want to plug in a value that we know is on this line: in this case, I will use the second point (-1, -4). Plug in the x and y values into the x and y of the standard equation.

-4 = 3/5(-1) + b

Multiply.

-4 = -3/5 + b

Add 3/5 to both sides. -- To add it easier, convert 4 to a have a denominator of 5.

-20/5 = -3/5 + b

-20/5 + 3/5 = b

-17/5 = b

Now, plug this into your standard equation.

y = 3/5x - 17/5

Check this equation by plugging in the other point you did not use (4, -1)

-1 = 3/5(4) - 17/5

-1 = 12/5 - 17/5

-1 = -5/5

-1 = -1

Your answer is correct!

Hope this helps!

Answers

The answer is C .
It’s not A because photosynthesis happens in plants which do not have a bloodstream and it’s not B because carbon dioxide is taken out of the air and oxygen is released into the air.

Answer:

C During the process of photosynthesis, cells use carbon dioxide and energy from the Sun to make sugar molecules and oxygen. ... Then, via respiration processes, cells use oxygen and glucose to synthesize energy-rich carrier molecules, such as ATP, and carbon dioxide is produced as a waste product

2x-1-(-x+3) = 6-2x SHOW STEPS....DUE TODAY

Answers

Answer:

x=2

Step-by-step explanation:

Simplify both sides of the equation.

2x−1−(−x + 3)=6−2x

(Distribute the Negative Sign)

2x−1 + −1(−x + 3)=6−2x

2x + −1 + −1(−x) + (−1)(3)=6−2x

2x + −1 + x + −3=6−2x

2x + −1 + x + −3=6 + −2x

(Combine Like Terms)

(2x + x) + (−1 + −3)=−2x+6

3x + −4=−2x + 6

3x−4=−2x + 6

Add 2x to both sides.

3x−4 + 2x=−2x + 6 + 2x

5x−4=6

Add 4 to both sides.

5x−4 + 4=6 + 4

5x=10

Divide both sides by 5.

5x/5=10/5

x=2
