Answer:
No
Step-by-step explanation:
x=5 produces y=3 and y=5 so the relation is not a function.
Yes that is function by looking that this
y
simplify 3x(4x-5)+3 and its value for X = 3
Answer:
Step-by-step explanation:
3x ( 4x - 5 ) + 3
12x^2 - 15x + 3
12 × 3^2 - 15 × 3 + 3
12 × 9 - 45 + 3
= 108 - 45 + 3
= 66

Which is a solution of 2(t-1)+3t<2?
t < 0.8
t ∈ ( - oo ; 0.8 )
Step-by-step explanation:Hi there !
2(t - 1) + 3t < 2
2t - 2 + 3t < 2
5t < 2 + 2
5t < 4
t < 4/5
t < 0.8
t ∈ ( - oo ; 0.8 )
Good luck !

Write an equation of the line passing through point P(4,3) that is parallel to the line y = 12(x+4).
Answer:
y=12x-45
Step-by-step explanation:
First we want to get y=12(x+4) into Slope intercept form which is y=mx+b and we do that by multiplying 12 by x so we get 12x and multiplying 12 by 4 so we get 48.
Now we have:
y=12x+48
where the slope is 12.
Parallel lines have the same slope. so the line that goes through (4,3) will have the same slope.
Now that we have a slope and a point we want to write an equation in point-slope form: y-y1=m(x-x1)
Step 1 for this: y-3=12(x-4)
Step 2: we will distribute and solve for y so our answer is in slope intercept form.
Step 3: we now have the equation y-3=12x-48 after distributing now we add 3 to -3 so it cancels out and we add 3 to -48 and we get -45
Our answer is y=12x-45
Hope this helps!

Bill cut out 6 squares and 8 circles . He divided the cutouts into groups so that the same number of squares and circles were in each group. What is the greatest number of groups he could have made?
Answer:
2 groups
Step-by-step explanation
To find out how many groups can be made for 6 circles and 8 squares, start by finding what you can divide by both numbers.
6 can be divided by: 8 can be divided by:
1 1
2 2
3 4
6 8
The greatest number that they both have in common is 2. There would be 3 circles and 4 squares if Bill divided into 2 groups.
I hope this helped. Let me know if you still have any questions!

Judy works as a quality inspector on a TV assembly line. She is required to inspect 9 TVs every 30 minutes. At this rate, how many should she inspect during 5 and half hours of work?
Answer:
99 TVs
Step-by-step explanation:
5 and a half hours is about 330 minutes.
9:30 = x:330
If 30 * 11 = 330, then 9 * 11 will equal x.
Judy should inspect 99 TVs.

Write the equation of the line in point-slope form that passes through the
given point with the given slope.
(-4, 3); m = 2
Answer:
y = 2x + 11
plug the values into y = mx+b:
3 = 2(-4) + b
solve, and you get
3 = -8 + b
b= 3+8 = 11
so, the equation is y = 2x+11
