Iteru [2.4K]

Answer:

y-30 = 3(x-1)

Step-by-step explanation:

Point-slope form of an equation is

y-y1 = m(x-x1) where (x1,y1 ) is a point and m is the slope

We know on day 1 they exercised 30 minutes (1,30) where x is the number of days and y is the minutes. The rate increased 3 minutes each day so m = 3

y-30 = 3(x-1)

SELECT ALL The Points that are on the Graph of the line 3x + 2y = 28 (:

Oksana_A [137]

<h2>Answer:</h2>

<h2>Step-by-step explanation:</h2>

points are on the graph of the line:-

$\tt{3x+2y=28 }$ ⠀

we get,

$\rightsquigarrow$ $\tt{ 2y=28-3x }$ ⠀

$\rightsquigarrow$ $\tt{y=\dfrac{28-3x}{2} }$ ⠀

In,(0,14)

If we put the value ,x=0

y= $\tt{\dfrac{ 28-3×0}{2}=\dfrac{28}{2}=14 }$

So,we get one point,(0,14)✔

In,(2,11)

If we put ,x=2

y= $\tt{\dfrac{28-3×2}{2}=\dfrac{28-6}{2}=\dfrac{22}{2}=11 }$

so,we get another point (2,11)✔

in other given ponts{(1,12),(4,9),(8,4)},It is impossible. ⠀ ⠀

Step-by-step explanation:

there 5^(n+1) + 5^(n+2) = 5^n x 5^1 + 5^n x 5^2 breaking them as x^(a+b) = x^a x x^b

then taking common 5^n from both terms
