c. 6.8m-7.2+8.7k

(2.4k-7.4)+(6.3k-2.2)+(6.8m+2.4) combine like terms

2.4k+6.3k+6.8m-7.4-2.2+2.4\\9.7k+6.8m-9.6+2.4\\9.7k+6.8m-7.2

Find the slope of the line between points A and B. Simplify your answer.
Taya2010 [7]

Answer:

-2

Step-by-step explanation:

From the given graph, the point A(1, -4) and B(-1, 0)

Slope (m) = (y2 - y1) / (x2 - x1)

x1 = 1, y1 = -4, x2 = -1 and y2 = 0

Slope (m) = (0 - (-4))/(-1 - 1)

= 4/-2

Slope = -2

Thank you.

Translate to an equation and solve: The sum of two-fifths and f is one-half.<br> Provide<br> f=
SCORPION-xisa [38]

Answer:

9/10

1/2+2/5

Since these fractions have different denominators, we need to find the least common multiple of the denominators.The least common multiple of 2 and 5 is 10, so we need to multiply to make each of the denominators = 10

1/2 ∗ 5/5 = 5/10

5/2∗ 2/2= 4/10

Since these fractions have the same denominator, we can just add the numerators

5/10+ 4/10 = 9/10

Five hundred dollars more than 10% of am amount of money $m is $1280. Find m.
In-s [12.5K]
For this one, we need to make an equation to make it look easier
(0.10 × m) + 500 = 1280
We solve for m
Subtract 500 from both sides and we get
0.10 × m = 780
Now, divide both sides by 0.10
And m would be equal to 7800
Let's see if this is correct.
Five hundred dollars more than 10% of m
We found that 10% of m is 780, now we add 500 to make the statement true. It will give us a total of 1280, which is equal of what the question says.
I hope this helps.
YOU'RE WELCOME :D
