It would be 28+63. you just have to use the distribution property so you’d do 7*4=28 and then 7*9=63. so all together it would be 28+63

SashulF [63]

Answer:

9 is the right answer

Step-by-step explanation:

I. If c = - 4 and d = 10

      then \frac{1}{4}(-4^{3} + 10^{2}  )

           = \frac{1}{4}(-64 + 100)

          = \frac{1}{4}(36)

          = 9

Hope that help :D

Please help me fast!!
elixir [45]

Answer:

y = -\frac{1}{4}x

Step-by-step explanation:

1. The slope-intercept form of a linear equation is y = mx + b, where y = y-coordinate, m = slope, x = x-coordinate, and b = slope.

2. To find the slope, let's take the two points (0,0) and (-40,10). After that, let's plug in the values to their corresponding variable in the formula: \frac{y_2-y_1}{x_2-x_1}

  • \frac{10-0}{-40-0}
  • \frac{10}{-40}
  • -\frac{1}{4}

3. Since we now know our slope, the equation looks like this so far: y = -\frac{1}{4}x + b.

4. Because b is the y-intercept, b = 0 because the line intersects the y-axis at (0,0).

5. Now that we have the values of m and b, we plug in them to get the equation of: y=-\frac{1}{4}x

uranmaximum [27]
To start off, simplify the equation if needed:
3m>=21
Since both sides are divisible by 3, you can simplify for the equation to be

m>=7

Next is to find the domain of the line graph. Since the sign is more than or equal to (>=), the circle is closed.
And since m is MORE THAN OR EQUAL TO, the section starts at 7 (closed circle), and continues after. Therefore, your answer will be the third selection.
