Write the slope and y intercept of each equation:
vichka [17]

Answer:

A) slope = 2, y-intercept = -6

B) slope = -4, y-intercept = 6

Step-by-step explanation:

A) y = 2x - 6

The equation for a line is y = mx + b, where <em>m</em> represents the slope, and <em>b</em> represents the y-intercept. So, to find the slope and y-intercept, all we have to do is look at the line's equation.

Here, the <em>m </em>is 2, so the slope is 2

The <em>b</em> is -6, so the y-intercept is -6

B) y = -4x + 6

Here, the <em>m</em> is -4, so the slope is -4

The <em>b </em>is 6, so the slope is 6

You would graph the equation y = 4x + 6 by plotting a point at the y-intercept of the line, which would be 6. Then, for every time you move one space to the right, you'd plot a point four spaces up to show the slope of four.

Mike can build a go cart in 30 days, Jed can build one in 20 days and Erick in 60 days. If all of them share the work, how quick
Gwar [14]

Answer: 10 days

<u>Step-by-step explanation:</u>

Mike: \frac{x}{30}

Jed: \frac{x}{20}

Erick: \frac{x}{60}

Together: \frac{x}{30} + \frac{x}{20} + \frac{x}{60} = 1

60(\frac{x}{30} + \frac{x}{20} + \frac{x}{60} = 1)

2x + 3x + x = 60

             6x = 60

               x = 10

Please help me ill put the question up for a lot of point, and i will mark as brainliest!!!
sattari [20]

Step-by-step explanation:

(2x³y^-4)^-2 = 1/(4x⁶y^‐8) = y⁸/(4x⁶)

1/(8x⁵y^-7) = y⁷/(8x⁵)

4x^-9y⁴ = 4y⁴/x⁹

so, the whole expression is then

y⁸/(4x⁶) × y⁷/(8x⁵) × 4y⁴/x⁹

4y¹⁹/(32x²⁰) = y¹⁹/(8x²⁰)

so, D is the correct answer.
