Step-by-step explanation:
G(f(2+x))=g(2+x)^2+3(2+x)=2(2+x)^2+3(2+x)-2=2(4+4x+x^2)+6+3x=8+8x+2x^2+6+3x=2x^2+11x+14
Answer:
y=-2x+15
Step-by-step explanation:
So first we can write it in point slope form.
That is y-y1=m(x-x1)
y1 is the y coordinate
m is the lope
x1 is the x coordinate
This means that the equation is:
y-7=-2(x-4)
We can then convert it to slope intercept form which is
y=mx+b
so
y-7=-2x+8
y=-2x+15
Answer:
60 oz of water to add
45 oz of 35% salt solution should be used
Step-by-step explanation:
Let x = amt no. ounces in the first solution
and 105 - x = amt no. of ounces in the second solution
Ist solution contains 0% salt
2nd solution contains .35(105 - x) salt
.15(105= amt of salt in mix
So.
amt of salt in 1st solution + amt of salt in 2nd solution = amt of salt in the mix
0 + .35(105 - x) = .15(105)
Let's get rid of the fractions by multipying thru the equation by 100
35(105 - x) = 15(105)
3675 - 35x = 1575
-35x = -2100
x = 60 oz of water to add
105 - 60 = 45 oz of 35% salt solution should be used
