Question 4 Multiple Choice Worth 3 points)

1 answer:

6 0

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

Answer:

Step-by-step explanation:

280 + 5(–5) + (–42) + 2(75) + (–200)

280 - 25 - 42 + 150 - 200

280 - 67 + 150 - 200

280 - 67 - 50

213 - 50

I need help please don't know this

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

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

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.
