The formula for the area of a triangle is (1/2)bh = A
when we plug in the numbers, we get (1/2)(3x-1)x = A
using the distributive property we get (1.5x - .5)x = A
Then its 1.5x^2 - .5x = A
then if we factor out 0.5x we get 0.5x(3x-1) = A
then with the zero product property, 0.5x can equal 0 and x would need to equal 0.
if 3x-1 = 0 , then 3x = 1 then x = 1/3. so our answer would be 1/3 I'm pretty sure because a length cannot be 0
Answer:
rotation
Step-by-step explanation:
"Isometric" means all measures stay the same.
- dilation changes all lengths
- <em>rotation changes no measures -- an isometric transformation</em>
- side length change obviously changes the length of a side
- angle change obviously changes the measure of an angle
Answer:
Step-by-step explanation:
To analyse a graph you are meant to determine a general trend, relating the results of an experiment to the hypothesis as well as to form. For example you look at all the values in a line graph and you are yo predict one you are to find its common increase or decrease.
If all possible vertical lines will only cross the relation in one place, then the relation is a function.This works because if a vertical line crosses a relation in more than one place it means that there must be two y values corresponding to one x value in that relation.
if x= 7 what is the value of x-4
7 - 4
=3
if y=3 what is the value of 8y
8 x 3
= 24
if x=7 what is the value of 3x-4
(3 x 7) - 4
= 17
if x=7 and y=3 what is the value of 2x-7y
(2 x 7) -(7 x 3)
= - 7
if x=7 and y=3 what is the value of 4y-X
(4 x 7) - 3
= 25
Hope this helps
