Answer:
Width 130 ft and
Length 320 ft
Step-by-step explanation:
We are given;
- Length of the rectangular base is 70 ft less than three times the width;
- Perimeter of the rectangular base is 900 ft
We are required to determine the dimensions of the rectangular base;
Assuming the width of the rectangular base is x ft
Then length will be (3x - 70) ft
But;
Perimeter = 2L + 2W
Thus;
900 ft = 2(3x-70) + 2(x)
900 ft = 6x -140 +2x
1040 = 8x
x = 130
Thus;
Width = 130 ft
Length = 3x -70 = 320 ft
Hence the dimensions of the rectangular base are width 130 ft and length 320 ft
I can't really tell if the question is asking about 7 or -7, so I'll give the answer for both.
A multiplicative inverse for 7 is a number you can multiply by 7 to make it equal to 1. In terms of an equation, you would get 7x = 1. We can then solve for x by dividing both sides by 7. So x = 1/7.
For -7, you would be able to solve the same equation as above just with -7 in the place of 7. You would end up with x = -1/7.
Slope intercept form is: y=mx+b
So you take the first equation: 2x-3y=6 and you subtract the 2x from both sides and get: -3y= 2x+6
Then you take that equation: -3y= 2x+6 and divide -3 from both sides and get: y= -2/3x -2
So the equation 2x-3y=6 in slope intercept from is
y = -2/3x -2
Can you do the next one your self based on the one i did...?
(Scroll and check ⬇️ )
Here ya go ;)
5x + 2y = 3 okay same steps as above you want to get the x on the other side so you subtract the 5x from both sides and get:
2y = 5x + 3
Then you want to get the y by its self so you divide the 2 from both sides so you get:
y = 5/2x +2/3
Now idk if your allowed to leave it like that (based on your teacher's preferance really) but if not you can simplfy your fractions and get:
y = 2.5x + 0.66
( i would leave the 2/3 and just leave it as y = 2.5x + 2/3 ) but you do you and i hope that helped you :)
Answer:
i think its the third one
Step-by-step explanation: im srry if im wrong doe
The first one is 2x^2+2x-2
the second one is 2x^2-2x-2
the third one is 6h+6k
