Find the equation of the line with slope = -7 and passing through (-7,51). write your equation in the form y=mx+b
muminat

Answer:

y = -7x + 2

Step-by-step explanation:

Since we do not have the y-intercept (or, when the x is 0) We will use the Slope Form Formula (y - y1 = m(x - x1)) to find the Slope Intercept Form Formula (y = mx + b)

Point: (-7,51)

Slope: -7

y - y1 = m(x - x1)

y - 51 = -7(x - (-7))

y - 51 = -7(x + 7)

y - 51 = -7x - 49

y = -7x - 49 + 51

y = -7x + 2

A certain ferry moves up and down a river between Town A and
Blizzard [7]

Answer: 60 miles

Step-by-step explanation:

Given

It takes ferry 2 hours to travel to town A and only 1.5\ hr to travel back to town B.

Speed of current is u=5\ mph

Suppose the speed of the ferry is v mph

Distance traveled in both the cases is same, but it took more time traveling to city A that is, ferry is moving upstream and downstream for returning time.

\Rightarrow 2(v-5)=1.5(v+5)\\\Rightarrow 2v-10=1.5v+7.5\\\Rightarrow 0.5v=17.5\\\Rightarrow v=35\ mph

Distance between the towns is 2\times (35-5)=60\ \text{miles}

If p(x) = 2x^3 - 3x + 5, what is the remainder of p(x) divided by (x - 5)
Alenkinab [10]

The question is

if p(x)= 2x³-3x+5, what is the remainder of p(x) divided by (x-5)

We use the synthetic division to find the remainder,

x-5=0

x=5

Now, write the coefficients of polynomial.


5 | 2  0  -3    5

   | ↓ 10  50  235

-------------------------------

     2 10  47  | 240→ is the remainder.

Quotient= 2x²+10x+47


Remainder= 240
