@Maizetycorn HELP with my previous questions pleaseeee! URGENT

Juli2301 [7.4K]

Answer:

z=-3

Step-by-step explanation:

The given line has slope m=-7.

The line passes through (-1,-8) and (z,6).

We use the slope formula:

$m=\frac{y_2-y_1}{x_2-x_1}$

We substitute $x_1=-1$ , $y_1=-8$ , $x_2=z$ , $y_2=6$ and $m=-7$ to get:

$-7=\frac{6--8}{z--1}$

$-7=\frac{6+8}{z+1}$

$-7=\frac{14}{z+1}$

$-7(z+1)=14$

Expand $-7z-7=14$

$-7z=14+7$

$-7z=21$

$z=-3$

Pls help! if given f(x) =-4x-2 and g(x) =2x, what is (f•g) (x)?

Tpy6a [65]

Set up the equation:

$(-4x - 2) \times 2x$

Distribute 2x to both of the terms in parentheses:

$-4x \times 2x = -8x^{2}$
$-2 \times 2x = -4x$

$-8x^{2} - 4x$

The answer is B.

Trevor and $826 on account during 2.5% annual interest for seven years.

photoshop1234 [79]

Trevor invested $ 4720

Solution:

Given that, Trevor earned $ 826 on account during 2.5% annual interest for seven years

We can simple interest formula

The formula for simple interest is given as:

$\text{ Simple Interest } = \frac{p \times n \times r}{100}$

Where,

"p" is the principal

"n" is the number of years

"r" is the rate of interest

Here given that,

Principal = p = ?

rate of interest = r = 2.5 %

number of years = n = 7

Simple interest earned = 826

Substituting the values in above formula,

$826 = \frac{p \times 7 \times 2.5}{100}\\\\82600 = p \times 7 \times 2.5\\\\82600 = 17.5p\\\\p = \frac{82600}{17.5}\\\\p = 4720$

Thus he invested $ 4720
