Answer:

$y = \frac{4}{5} x + 2$

Step-by-step explanation:

Put the slope value given as the coefficient of x.

It is the "m" in the formula y = mx + b

I'm not sure what the other equations in the question are there for. Maybe to change from slope-intercept form to standard form?

y = 2x +

y = x – 2 becomes y -x = -2 or x - y = 2

y = x + 2 becomes y -x = 2 or x - y = -2

Answer:

k = 13The smallest zero or root is x = -10

Step-by-step explanation:

you can write "x^2" to mean "x squared"

f(x) = x^2+3x-10

f(x+5) = (x+5)^2+3(x+5)-10 ... replace every x with x+5

f(x+5) = (x^2+10x+25)+3(x+5)-10

f(x+5) = x^2+10x+25+3x+15-10

f(x+5) = x^2+13x+30

Compare this with x^2+kx+30 and we see that k = 13

Factor and solve the equation below

x^2+13x+30 = 0

(x+10)(x+3) = 0

x+10 = 0 or x+3 = 0

x = -10 or x = -3

The smallest zero is x = -10 as its the left-most value on a number line.

Suppose $600 is compounded yearly for 20 years. If no other deposits are made, what rate is needed for the balance to triple in

denis-greek [22]

Answer:

5.65%

Step-by-step explanation:

Principal=$600

Time=20 years

FV=600*3=$1800

n=1

r=?

r= n[(A/P)^1/nt - 1]

=1{(1800/600)^ 1/1*20 - 1}

={(3)^1/20-1}

=3^0.05-1

=1.0565-1

=0.0565

rate=0.0565*100

=5.65% to the nearest hundredth percent
