Answer:
25/4
Step-by-step explanation:
perimeter is total length of all side
height =2(x+2) (×2 bcause has 2 side)
length =2(3x-1) (×2 bcause has 2 side)
2x+4+6x-2=52
8x-2=52
8x=50 (8x is 8 times x, so move to the other side become divide)
x=50/8
simplify
x= 25/4
Y=5(3/2)^x is this model exponential growth,decay or neither ?
Y - 3 = -1/4(x - 4)
y - 3 = -1/4x + 1
y = -1/4x + 1 + 3
y = -1/4x + 4
ok....the y int is (0,4)....the slope is -1/4...
x int can be found by subbing in 0 for y and solving for x
y = -1/4x + 4
0 = -1/4x + 4
1/4x = 4
x = 4 * 4
x = 16....so ur x int is (16,0)
so first plot ur points (0,4)....and since ur slope is -1/4, go down 1 space and to the right 4 spaces, then down 1, and to the right 4....keep doing this and u will cross the x axis at (16,0)
Answer:
the answer is 2.2
Step-by-step explanation:
I used a calculator
The answer is: 8 red marbles!
This is because the equation can be written out like this
Blue to red - 3:2
Now it is, blue to red - 12:x
We have to think, what is the difference from the first equation to the second. We know the number 3 times 4 = 12, so we would do the same for the red, 2 times 4=8
If this helped, give me brainliest :)
