The value of the (RIC) will increase from 4 to 5.75,that is,44%
Answer:
D. –10
Step-by-step explanation:
Given equation:
y = 3x – 1
what is the value of y when x equals –3?
Substitute x = -3 into the equation to find y
y = 3x – 1
= 3(-3) - 1
= -9 - 1
= -10
y = -10
The correct answer is D. –10
Answer:
see below
Step-by-step explanation:
x < 4
x is less than 4
Since it is less than, there is an open circle at 4
less than means the line goes to the left
Answer:
The answer is 2/3
Step-by-step explanation:
Let's solve your equation step-by-step.
2/
3(x)=4/9
Step 1: Multiply both sides by 3/2.
(
3/2)*(2/3*x)=(3/2)*(4/9)
so this means the answer is 2/3
Each triangle has a side length of 1, which is why the perimeter of the single triangle is 3. We just add up the three sides (1+1+1 = 3).
Similarly, the perimeter of the second figure is 4 because we have 4 sides that are same length which add up to 4 total (1+1+1+1 = 4).
Pattern #3 has a perimeter of 5 because the bottom length is 2 units long, the top length is 1 unit long, and each diagonal is 1 unit long. So we have 5 total.
The perimeters so far are: 3, 4, 5
Each time we are adding 1 to the old perimeter to get the new perimeter. So pattern #4 will have a perimeter of 6. Sure enough, if you count the sides out, then you should get 6 total.
Note: only count out the exterior sides. Do not count the interior sides.
--------------------------------------------------------------------
x = number of triangles, y = perimeter
If x = 1, then y = 3
If x = 2, then y = 4
if x = 3, then y = 5
If x = 4, then y = 6
Whatever x is, we add on 2 to get the value of y.
So the equation is therefore y = x+2. If you want, you can use the slope formula to find the value of m. Then use it to find the value of b, so you determine that y = mx+b turns into y = 1x+2 which is the same as y = x+2
Answer: y = x+2
