f(x) = x+.50(x)

where x is the amount the math club raises and

.5x is the amount the principal donates

f(x) is the amount of money for the field trip

we can simplify this to

f(x) = 1.5x by combining like terms

using the original equation

f(150) = 150 + .5(150)

f(150) = 150 +75

f(150) =225

using the simplified equation

f(150) = 1.5(150)

f(150) =225

Which equation is equivalent to –k + 0.03 + 1.01k = –2.45 – 1.81k? –100k + 3 + 101k = –245 – 181k –100k + 300 + 101k = –245 – 18
NNADVOKAT [17]
<span>The answer is -100k + 3 + 101k = -245 - 181k. In the equation –k + 0.03 + 1.01k = –2.45 – 1.81k, numbers have two decimals. So, if we multiply both of sides by 100, we will get whole numbers: 100(–k + 0.03 + 1.01k) = 100(–2.45 – 1.81k). 100 * (-k) + 100 * 0.03 + 100 * 1.01k = 100 * (-2.45) + 100 * (-1.81k). -100k + 3 + 101k = -245 - 181k.</span>

Line AB goes through the points A (0, –4) and B (6, 2). Which equation represents line AB?
Contact [7]

Answer:

The slope is 1/3.

Step-by-step explanation:

To solve this problem you had to use the slope of an equation represents the line.

Slope formula:

\displaystyle \frac{Y_2-Y_1}{X_2-X_1}

\displaystyle \frac{2-4}{6-0}=\frac{-2}{6}=\frac{-2\div2}{6\div2}=\frac{-1}{3}=-\frac{1}{3}

Therefore, the slope is 1/3, which is our answer.

Hope this helps!
