Rewrite! Write an new and equivalent equation that is easier to solve

Marysya12 [62]

$\huge\underline{\red{A}\blue{n}\pink{s}\purple{w}\orange{e}\green{r} -}$

Given - an equation in a standard form

To do - simplify the equation so as to obtain an easier one

Since the equation provided isn't in it's general form , let's first convert it ~

General form of a Linear equation -

$\bold{ax + b = 0}$

The equation after getting converted will be as follows ~

$- 7 + ( \frac{4x + 2}{2} ) = 8 \\ \\ \implies \: \frac{ - 14 + 4x + 2}{2} = 8 \\ \\ \implies \: - 14 + 4x + 2 = 16 \\ \\ \implies \: 4x = 16 + 14 - 2 \\ \\ \implies \: 4x = 28 \\ \\\bold{ General \: form \: \dashrightarrow \: 4x - 28 = 0}$

hope helpful ~

How to do number 13 and 14

Murrr4er [49]

From the information: v is 64 while c is 5

Differentiate the new equation h=-16 $t^{2}$ + 64t + 5 to get $\frac{dh}{dt}$ = -32t + 64.

no 13). At maximum height this derivative equals zero so: -32t + 64 = 0; -32t = -64; t=2.Hence ans is 2 secs

no 14). put t as 2 sec in the equation: h=-16 $t^{2}$ + 64t + 5. This gives

h=-16( $2^{2}$ ) + 64(2) + 5; h=-64+128+5=69. Hence h is 69ft

Answer:

Step-by-step explanation:

this needs evaluation of Bella's income on every chore.

say when c = 1, d = 3.5*1+11= 14.5

c=2 d = 3.5*2+11= 18..evaluate for c=3,4,5.

with that it can be found that bella earns more than sweet t. so choice c
