Answer:

y = 7

Step-by-step explanation:

Equate the equation to equal 0.

8(y-7) = 0

Open up the bracket:

8y - 56 = 0

Add 56 to both sides:

8y = 56

Divide both sides by 8:

y = 7

Your dog eats 7/8 lb of food in 4 meals , how many meals will it take your dog to eat 1 lb of food

chubhunter [2.5K]

Answer:

I would say 1 lbs of dog food is equivalent to 4 4/7 meals.

7/8 lbs : 4 meal = 1 lbs : x meals 1 lbs = 8/8 lbs perform cross 7/8 lbs (x) = 8/8 * 4 7x/8 = 8*4 / 8*1 7x/8 = 32/8 7x/8 = 4 8(7x/8) = 8*4 7x = 32 7x/7 = 32/7 x = 4 4/7 meals to 7/8 : 4 = 1 : 4 4/7 7/8 * 32/7 = 4 * 1 224/56 = 4 4 = 4

Which equation describes a line parallel<br> to y= 4x+ 5 through point (-2, 1)?

Tema [17]

Hi there!

For a line to be PARALLEL, it must contain the same slope.

The given line has a slope of 4, so we can use the point-slope formula to solve:

$\large\boxed{y - y_1 = m(x - x_1)}$

y1 = y-coordinate of given point

x1 = x-coordinate of given point

m = slope

Plug in the values:

$y - 1 = 4(x - (-2))\\\\y - 1 = 4(x + 2)$

Simplify:

$y - 1 = 4x + 8\\\\\boxed{y = 4x + 9}$

Write the quadratic equation in general form and then choose the value of "b." (2x - 1)(x + 5) = 0

Snezhnost [94]

General form is ax^2+bx+c, and to get there we need to factor using FOIL (First Outside Inside Last)
(2x-1)(x+5)
F (2x × x)= 2x^2
O (2x × 5) 10x
I (-1 × x) -x
L (-1 × 5) -5
now add them together
2x^2+10x-x-5
2×^2+9x-5
and because the equation is in the form
ax^2+bx+c b is equal to 9

Find the slope of the line that passes through the pair of points.<br> (6, 1), (-6, 1)

GrogVix [38]

Answer: m = 0

Step-by-step explanation: To find the slope of the line, we can use the graphing method. To do this, we start by plotting our two points.

Let's label (6, 1) as point A and (-6, 1) as point B.

Now, graph our line through the 2 points.

Now remember that the slope, or m, is equal to

the rise over run from point A to point B.

To get from point A to point B, we rise o units and run -12 units.

So our slope or rise / run is 0/-12 which simplifies to 0.

This should make sense because we have a horizontal or flat line and

remember that the slope of any horizontal or flat line is 0.
