Your answer is either C or D. But I strongly believe that the answer would possibly be C.

-5/4x - 2)=-2(3 +6x)

Alex

Answer:

x = (-16)/43

Step-by-step explanation:

Solve for x:

(-5 x)/4 - 2 = -2 (6 x + 3)

Put each term in (-5 x)/4 - 2 over the common denominator 4: (-5 x)/4 - 2 = (-5 x)/4 - 8/4:

(-5 x)/4 - 8/4 = -2 (6 x + 3)

(-5 x)/4 - 8/4 = (-5 x - 8)/4:

(-5 x - 8)/4 = -2 (6 x + 3)

Multiply both sides by 4:

(4 (-5 x - 8))/4 = -2×4 (6 x + 3)

(4 (-5 x - 8))/4 = 4/4×(-5 x - 8) = -5 x - 8:

-5 x - 8 = -2×4 (6 x + 3)

4 (-2) = -8:

-5 x - 8 = -8 (6 x + 3)

Expand out terms of the right hand side:

-5 x - 8 = -48 x - 24

Add 48 x to both sides:

48 x - 5 x - 8 = (48 x - 48 x) - 24

48 x - 48 x = 0:

48 x - 5 x - 8 = -24

48 x - 5 x = 43 x:

43 x - 8 = -24

Add 8 to both sides:

43 x + (8 - 8) = 8 - 24

8 - 8 = 0:

43 x = 8 - 24

8 - 24 = -16:

43 x = -16

Divide both sides of 43 x = -16 by 43:

(43 x)/43 = (-16)/43

43/43 = 1:

Answer: x = (-16)/43

2. Define the absolute value function, y = |x|, as a piecewise function. Please include complete sentences and examples to justi

Mekhanik [1.2K]

Y = |x| = x if x ≥ 0, -x if x < 0

absolute value can be interpreted as a function that does not allow negative real numbers, forcing them to be positive (leaving 0 alone). if the input x is more than or equal 0, then x stays positive so there is no need to do anything: "x if x ≥ 0".
if the input is less than 0, then it is an negative number and needs a negative coefficient to negate the negative: "-x if x < 0"

example: if x = -3, then it will take the "-x if x < 0" piece resulting in y = -(-3) = 3, which is what |-3| does

if x = 1, it will take the "x if x ≥ 0" piece and just have y = 1 which is what |1| does.

for x = 0, it will take the "x if x ≥ 0" and just have y = 0 which is what |0| does

You are making payments for a $1,475 loan that has a simple interest rate of 7.54% for 5 years.

lbvjy [14]

Answer:

$2,031.08

Step-by-step explanation:

You want to calculate the interest on $1475 at 7.54% interest per year after 5 year(s).

The formula we'll use for this is the simple interest formula, or:

I=P x r x t

P is the principal amount, $1475.00.

r is the interest rate, 7.54% per year, or in decimal form, 7.54/100=0.0754.

t is the time involved, 5....year(s) time periods.

So, t is 5....year time periods.

To find the simple interest, we multiply 1475 × 0.0754 × 5 to get that:

The interest is: $556.08

Usually now, the interest is added onto the principal to figure some new amount after 5 year(s),

or 1475.00 + 556.08 = 2031.08. For example:

If you borrowed the $1475.00, you would now owe $2031.08

If you loaned someone $1475.00, you would now be due $2031.08

If owned something, like a $1475.00 bond, it would be worth $2031.08 now.
