Answer:
-81
Step-by-step explanation:
f(x) = 8x -1
f(-10) = 8(-10) -1
f(-10) = -80-1
f(-10) = -81
Answer:
$168
Step-by-step explanation:
The formula we'll use for this is the simple interest formula, or:
I=Prt
Where:
P is the principal amount, $2000.00.
r is the interest rate, 4.2% per year, or in decimal form, 4.2/100=0.042.
t is the time involved, 2....year(s) time periods.
So, t is 2....year time periods.
To find the simple interest, we multiply 2000 × 0.042 × 2 to get that:
The interest is: $168.00
Answer:

Step-by-step explanation:
For this case, what you should keep in mind are the following considerations:
1) Rewrite the expressions correctly using the properties of the exponents: Addition, multiplication, division, subtraction and negative exponents.
2) Simplify the expression as much as possible.
Answer:
See attached image.
The general form of a quadratic equation is that which is expressed in a form,
ax² + bx + c = 0
To write the equation in its general form, eliminate the decimal by multiplying the equation by 10. It now becomes,
3x² + 50x - 70 = 0
The value of b is therefore 50 and the answer is the second choice.
