Last year, Shen opened an investment account with $7800. At the end of the year, the amount in the account had decreased by 22.5% . How much is this decrease in dollars? How much money was in his account at the end of last year?
Answer:
The decrease was $1755.
At the end of the year, he had $6045 in his account.
Step-by-step explanation:
Start with $7800.
Decrease of 22.5% of $7800.
22.5% of $7800 =
= $1755
The decrease was $1755.
$7800 - $1755 = $6045
At the end of the year, he had $6045 in his account.
Given f(x) = | – 5 – 4x| ,find the following:
f(- 10) =
f(-11) =
f(12) =
f(2)=
Answer:
[tex]f(10) = 35 \\ \\ f( - 11) = 39 \\ \\ f(12) = 53 \\ \\ f(2) = 13[/tex]
Step-by-step explanation:
[tex] f(x) = | - 5 - 4x| [/tex]
To solve for the following substitute the value of x in the brackets into the above formula and solve for the value of x
NB: Absolute value of a negative number is the same number but positive.
So we have
[tex]f( - 10) = | - 5 - 4( - 10)| \\ = | - 5 + 40| = 35 \\ \\ f( - 11) = | - 5 - 4( - 11)| \\ = | - 5 + 44| = 39 \\ \\ f(12) = | - 5 - 4(12)| \\ = | - 5 - 48| \\ = | - 53| = 53 \\ \\ f(2) = | - 5 - 4(2)| \\ = | - 5 - 8| = | - 13| \\ = 13[/tex]
Hope this helps you

Evaluate: 2x + 28 < 100
Your answer I
Answer:
x<36
Step-by-step explanation:
subtract 28 from both sides
so now the problem is: 2x<72
divide both sides by 2: 2x/2<72/2
therefore: x<36
Raj is deciding between two cell phone plans, A and B, which are both linear functions. The monthly charge for plan A according to the number of minutes used is shown in the table. Monthly Charge for Plan A Minutes used, x Monthly charge ($), y 0 14.45 3 14.84 6 15.23 9 15.62 12 16.01 Plan B has the same monthly base charge as plan A, but it charges a different amount per minute used. If the total monthly charge for plan B is $22.10 when 45 minutes are used, what is the slope of the linear function that represents the cost of plan B?
Answer:
B
Step-by-step explanation:
The slope of the linear function for plan B is of $0.17.
---------------------------
A linear function has an equation in the following format:
[tex]y = mx + b[/tex]
In which
m is the slope, which is the rate of change, measuring how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0.---------------------------
Plan B has the same monthly base charge as plan A, that is, from the table, when [tex]x = 0, y = 14.45[/tex], and thus, (0, 14.45) is one of the points of the function.The monthly charge for 45 minutes is of $22.10, thus, another point is (45, 22.10).Given two points, the slope is given by the change in y divided by the change in x. Thus:[tex]m = \frac{22.1 - 14.45}{45 - 0} = 0.17[/tex]
The slope is of $0.17.

If 2x + y = 10, and 3x - y = 0, then y = ?
Answer:
y = 6
Step-by-step explanation:
2x + y = 10, and 3x - y = 0
We will use elimination
2x + y = 10
3x - y = 0
-----------------------
5x +0y = 10
5x = 10
Divide by 5
5x/5 = 10/5
x =2
3x - y = 0
3*2 -y = 0
6-y =0
Add y to each side

RS bisects TU at Q. If TQ=5k-9 and QU=15-x
Answer:
x = 4, TU = 22
Step-by-step explanation:
Given that TS bisects TU at Q , then
TQ = QU , substitute values
5x - 9 = 15 - x ( add x to both sides )
6x - 9 = 15 ( add 9 to both sides )
6x = 24 ( divide both sides by 6 )
x = 4
Thus
TU = 5x - 9 + 15 - x = 4x + 6 = 4(4) + 6 = 16 + 6 = 22
