translate into an algebraic expression: 120 is decreased by d% and increased by 25%. what is the result
s2008m [1.1K]

Answer:

150(1-x)

Step-by-step explanation:

120 is decreased by d%

Let x = d%

120 - 120*x

120(1-x)

Then it is increased by 25%

(120 (1-x)) +(120 (1-x))*.25

(120 (1-x)) +(30 (1-x))

150(1-x)

Can someone help me with this plz??
mamaluj [8]

Answer:

f(x) = -4x-1

f(7) = -(4)(7)-1

f(7) = -29

g(x) = 4x^2 - x

g(-4) = 4(-4)^2 - (-4)

g(-4) = 4(16) + 4

g(-4) = 64 + 4

g(-4) = 68

Let me know if this helps!

The summation expression in the following series has an absolute value in it. Expand and evaluate the summation notation. What i
nikitadnepr [17]
|3i-10|=\begin{cases}3i-10&\text{for }3i-10\ge0\\-(3i-10)&\text{for }3i-10

We have that 3, which means |3i-10| reduces to 3i-10 when i\ge4, or reduces to 10-3i when i\le3.

So we can expand the summation as

\displaystyle\sum_{i=1}^6|3i-10|=\sum_{i=1}^3(10-3i)+\sum_{i=4}^6(3i-10)

Notice that the 10 contributes a total of 30 from the first sum, and -30 from the second sum, so those terms cancel, leaving us with

\displaystyle3\left(\sum_{i=4}^6i-\sum_{i=1}^3i\right)=3((4+5+6)-(1+2+3))=3(15-6)=3(9)=27
