Add. Find the expression in standard form. (15y − 9 + 6y^2) + (10 − 5y) = _________

1 answer:

4 0

Wasnt sure if you were asking just for the standard form of that equation
<span>(15y − 9 + 6y^2) + (10 − 5y) = 0 ) or if you wanted the equation simplified and then in standard form ( 6y^2 + 10y + 1 = 6 ) so i did both </span>

I NEED HELP IDENTIFYING THE SLOPE PLEASE !!! Pic attatched !!!!

Alexus [3.1K]

Answer:

see explanation

Step-by-step explanation:

Calculate the slope m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = 2,4 ) and (x₂, y₂ ) = (5, 1)

m = $\frac{1-4}{5-2}$ = $\frac{-3}{3}$ = - 1 ← negative slope

Repeat

with (x₁, y₁ ) = - 7,8) and (x₂, y₂ ) = (- 7, 0)

m = $\frac{0-8}{-7+7}$ = $\frac{-8}{0}$

Division by zero is undefined, thus slope is undefined.

Repeat with

(x₁, y₁ ) = (6, - 3) and (x₂, y₂ ) = (- 4, - 3)

m = $\frac{-3+3}{-4-6}$ = $\frac{0}{-10}$ = 0 ← zero slope

Repeat with

(x₁, y₁ ) = (3, 5) and (x₂, y₂ ) = (- 1, 2)

m = $\frac{2-5}{-1-3}$ = $\frac{-3}{-4}$ = $\frac{3}{4}$ ← positive slope

Justin is getting cans of soda. It cost him $3 each week to advertise his business. He buys each can for $0.30 and sells each on

IrinaK [193]

Loss per week is -$3
Profit per can is $1.00 - $0.30 which is $0.70

Therefore then equation is
p = 0.7x - 3

A = a+b+c/3 Solve for b this is a literal equation problem please show steps

Elan Coil [88]

Answer:

$b=3A-a-c$

Step-by-step explanation:

$A=\frac{a+b+c}{3}$

Multiply both sides by 3

$3A=a+b+c$

Add $-b-c$ both sides

$3A-a-c=b$

$b=3A-a-c$
