Find the line parallel to the line y=3x+5 which passes through the point (1,4). a. y=-1/3x+1 b. y=-3x+1 c. y=1/3x+1 d. y=3x+1
Vladimir [108]

Answer:

D

Step-by-step explanation:

So we want to find the equation of the line parallel to y=3x+5 and goes through the point (1,4).

First, since the new line is parallel, its slope must be equivalent. Therefore, the slope of our new line <em>must</em> also be 3.

Now, we can figure out the rest of the equation using the point-slope form:

y-y_1=m(x-x_1)

Substitute 3 for m. Let's let (1,4) be x₁ and y₁. Thus:

y-4=3(x-1)

Distribute the right:

y-4=3x-3

Add 4 to both sides:

y=3x+1

And we're done!

The correct answer is D.

Solve the equation 9b2 + 30b + 25 = 0.
jeka57 [31]
Factor the equation into...
(3b+5)(3b+5)=0
Each factor 3b+5=0 so 3b=-5 so b=-5/3

Check:
9(-5/3)^2+30(-5/3)+25=
9(25/9)-50+25=
25-50+25=0
It checks,

So answer is A.-5/3
