noname [10]3 years ago
4 0

Answer:

x=-4, 3.

Step-by-step explanation:

x/(x+3)=4/(x+5)

cross product

4(x+3)=x(x+5)

4x+12=x^2+5x

x^2+5x-4x-12=0

x^2+x-12=0

factor out the trinomial,

(x+4)(x-3)=0

zero property,

x+4=0, x-3=0,

x=0-4=-4

x=0+3=3

Answer:

B

Step-by-step explanation:

they want us to find the equation in slope intercept form

which is y= mx + b

where m = slope and b = y intercept

the slope is change in y over change in x

as y goes up 1 x goes up 1 so the slope is 1 or m=1

the y intercept is at point (0,1)

so the y intercept is 1

now we add it all together and get that the equation Is

y=x+1
