Answer:

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

===============================

note: 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

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.

Step-by-step explanation: Hope this helps kind of.

Answer:

(8/5 , -2/5)

Step-by-step explanation:

x-y=2

2x+3y=14

-y=-x+2

y=x-2

2x+3(x-2)=14

2x+3x-6=14

5x-6=14

5x=8

x=8/5

y=(8/5)-2

y= -2/5

The ratio of Dina's bathing suit to yana is 4:1, if Dina has 24 more bathing suits than yana, how many bathing suits does yana h
Thepotemich [5.8K]
I'd say Yana has 6...

30\ 6 is 5

the ratio range is a group inside 5..

so Dina has 30 swim suits...which is 5 times 6 of yana.

so since Dina has 24 "more" than yana... Dina is 4 : Yana is 1....4:1
