Answer:

y = 2x + 7

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

here m = 2, so

y = 2x + c ← is the partial equation

To find c substitute (- 3, 1) into the partial equation

1 = - 6 + c ⇒ c = 1 + 6 = 7

y = 2x + 7 ← equation in slope- intercept form

here,

given point is (-3,2) and slope(m) is 2

so y=mx + b

or 2=2×(-3) +b

or b=8

the equation is

y=mx+b

or y=2x+8

or2x-y+8=0

a shopkeeper purchased a TV at ₹15,000 and gives a discount of 20% on its marked prize and still got a profit of 8% . find the m
Setler79 [48]

\huge\sf\underline{Answer}

\sf\longrightarrow selling \: prize \:   =  \frac{100 + profit\%}{100}  \times cp

\sf\longrightarrow  \frac{108}{100}  \times 15000 = 16200

Let the marked prize of the TV be x .

\sf\longrightarrow discount = 20\% \: of \: x \:  =  \frac{20}{100}x =  \frac{x}{5}

We have SP = MP - Discount

\sf\longrightarrow 16200 \:  =  \: x -  \frac{x}{5}

\sf\longrightarrow 16200 \:  =  \frac{4x}{5}

\sf\longrightarrow x \:  =  \: 20250

<em>Hence </em><em>,</em><em> </em><em>T</em><em>he </em><em>marked</em><em> </em><em>prize</em><em> </em><em>of </em><em>the </em><em>TV </em><em>is </em><em>₹</em><em>2</em><em>0</em><em>,</em><em>2</em><em>5</em><em>0</em><em> </em><em>.</em>

<em>Hope </em><em>it </em><em>helps </em><em>~</em><em> </em>

If (3a + 3b + 1) (3a + 3b - 1) = 80, then a + b =
seropon [69]

Answer:

a+b = 4\sqrt{3}

Step-by-step explanation:

3(a + b)^2 = 81

(a + b)^2 = 27

a + b = sq rt 27

a + b = \sqrt{9}· \sqrt{3}

a + b = 3\sqrt{3}

How would you translate this situation below into an algebraic expression?
Natasha2012 [34]
Dime value: $0.10
Nickel value: $0.05

For this word problem, you are asked to create an algebraic expression (an equation) for the unknown variables. 

Now, we know that a dime is worth $0.10 or 10 cents and a nickel is worth $0.05 or 5 cents. So, all you would have to do is create an equation that takes those values into account. 
5n + 10d

Your algebraic expression would be B. 5n + 10d

I hope this helps!

Rewrite the expression in the form y^n
bazaltina [42]

Answer:

$ y^6 $

Step-by-step explanation:

$ \frac{a^b}{a^c} = a^{b - c} $

Using this rule we have:

$ \frac{y^{-7}}{y^{-13}}  = y^{-7 -(-13)} = y^6$
