The standard form of equation is: 4x+2y = -13

Step-by-step explanation:

the standard form of a linear equation in two variables is given by:

$ax+by = c$

Given equation is:

$2y+5=-4(x+2)$

Distributing -4 into the round bracket

$2y+5 = -4x-8$

Adding 4x on both sides

$4x+2y+5 = -4x-8+4x\\4x+2y+5 = -8$

subtracting 5 from both sides

$4x+2y+5-5 = -8-5\\4x+2y = -13$

The standard form of equation is: 4x+2y = -13

I need this answered please

Answer:

Second Option: 3, -3

Step-by-step explanation:

In the graph of the supplied function we observe f (x) is a piece wise function composed of two line segments and a point.

$f(x) = 3$ if $x$ , $f(x) = -3$ if $x> 2$ , $f(x) = 1$ if $x = 2$

We must find the limit when x approaches 2 from the left

$\lim_{x \to 2^-}f(x)$

and we must find the limit when x approaches 2 on the right.

$\lim_{x \to 2^+}f(x)$

when x approaches 2 on the left then $x$ . If $x$ then $f (x) = 3$ , therefore the $\lim_{x \to 2^-}f(x)=3$

When x approaches 2 on the right then $x> 2$ . If $x> 2$ then $f (x) = -3$ , therefore the $\lim_{x \to 2^+}f(x)=-3$ .

A principal of $4400 is invested at 8.25% interest, compounded annually. how much will the investment be worth after 15 year's?

vladimir2022 [97]

A = $ 9,845.00

Equation:
A = P(1 + rt)
Calculation:
First, converting R percent to r a decimal
r = R/100 = 8.25%/100 = 0.0825 per year,
then, solving our equation

A = 4400(1 + (0.0825 × 15)) = 9845
A = $ 9,845.00

The total amount accrued, principal plus interest,
from simple interest on a principal of $ 4,400.00
at a rate of 8.25% per year
for 15 years is $ 9,845.00.
