Answer:
Yes, the point (2,6) is on the graph of y=3x
Step-by-step explanation:
y = 3x
For the order pair (2,6)
substitute with x = 2 at the given function.
3x = 3 * 2 = 6
So, the point (2,6) on the graph of y=3x
Also, see the attached figure.
(3x^2 - 2x)(x + 4)
<em><u>First step would be: distributive property.</u></em>
3x^3 + 12x^2 - 2x^2 - 8x
<em><u>Combine like terms.</u></em>
3x^3 + 10x^2 - 8x is the simplified form of the functions multiplied.
Your answer is D.
Answer:
The correct unit price is $1.17 per pair of gloves. The error is she used number of dozens so, firstly convert it to number of pairs of gloves then divide.
Step-by-step explanation:
It is given 4 dozen pairs of gloves for $56.16.
So, unit price = Divide the price by number of pairs of gloves.
And 1 dozen =12
So 4 dozen =4*12=48 pairs of gloves
So, to find unit rate divide 56.16 by 48.
Unit price =
So, the error is she didn't convert the dozen to units.
That made mistake in finding unit price.
Answer:
3×20= 60.
Step-by-step explanation:
Given:
A researcher wants to run a 2 x 3 mixed factorial design.
1st factor is the subject within
2nd factor is the subject between
Now to calculate how many participants will he need in total
(greater of 2,3)×20
that is
=3×20= 60.
