Answer:

m=\frac{1}{2}

Step-by-step explanation:

The slope of a line, also known as the change in the line or the (\frac{rise}{run}) can be found using the following formula,

m=\frac{y_2-y_1}{x_2-x_1}

Where (x_1,y_1) and (x_2,y_2) are points on the line. Substitute the given information into the formula and solve for the slope.

m=\frac{y_2-y_1}{x_2-x_1}

Points on the line: (4,4)\ \ \ (10, 7)

m=\frac{y_2-y_1}{x_2-x_1}

m=\frac{7-4}{10-4}

m=\frac{3}{6}

m=\frac{1}{2}

m=0.5

  • (4,4)
  • (10,7)

\boxed{\sf Slope(m)=\dfrac{y_2-y_1}{x_2-x_1}}

\\ \sf\longmapsto m=\dfrac{7-4}{10-4}

\\ \sf\longmapsto m=\dfrac{3}{6}

\\ \sf\longmapsto m=\dfrac{1}{2}

\\ \sf\longmapsto m\approx0.5

1a) so for this problem, I took what they gave you, 637.5 and divided it by .75 and got 850

so .75 * 850 = the gallons, so just take the number of hours and multiply it by 850 to get your gallons

0.25 x 850 = 212.5

1.5 x 850 = 1,275

2.5 x 850 = 2,125

1b) the unit rate is 850

1c) 5.5 x 850 = 4,675 gallons

1d) So 850 gallons can be filled in an hour, you only need 100 gallons

850/100 = 17/2 (simplified)

17 gallons/hour 60 minutes

------------------------- x ---------------------

2 gallons 1 hour

the gallons cancel out and the hours cancel out which leaves us with:

17 x 60 = 1,020 / 2 = 510

510 minutes

2) I don't know how to do two sorry

Which system of linear inequalities Is represented by this graphed solution?
SashulF [63]

Answer:

y ≥ 3x - 1

y < -\frac{1}{2}x+2

Step-by-step explanation:

Let the equation of the solid line passing through (x', y') given in graph is,

y = mx + b

Here m = slope of the line

b = y-intercept

Slope of the solid line =

                                 m = \frac{3}{1}

                                 m = 3

y - intercept 'b' = -1

Therefore, equation of the line will be,

y = 3x - 1

Since, shaded (blue) area is above the line, inequality that will represent the solution area will be,

y ≥ 3x - 1

For the dotted line,

Slope of the line (m) = \frac{\text{Rise}}{\text{Run}}

                                  = \frac{-2}{4}

                                  = -\frac{1}{2}

y-intercept (b) = 2

Equation of the dotted line → y = -\frac{1}{2}x+2

Since, shaded (grey color) area is below the dotted line,

Inequality representing the solution area will be,

y < -\frac{1}{2}x+2

the width of the rectangle is 5 inches less than it's length, and the area is 84 square inches. what are the length and width of
inysia [295]
W= l - 5    where w = width and l = length

area = 84 = l*w = l(l-5)

l(l-5) = 84
l^2 - 5l - 84 = 0
(l - 12)(l  + 7) = 0 
l = 12 

length = 12 and width =  7

Write 3,272 in expanded form
rosijanka [135]
3272 I 2
1636 I 2
  818 I 2
  409 I 409    so bc. 409 is a prime number has factors of 409 and 1 
      1 I

so the expanded form of 3272 will be 2^3 *409

hope helped
