First equate 4x+7y=3x,
we get, x+7y=0 ---->equ 1
Now equate 3x=y-2, we get 3x-y=-2 ----->equ2
solve equ 1,2,
We get x= -7/11, y=1/11
Answer:
Step-by-step explanation:
Your start amount is $80
And you’ll be adding 5 every week
Y=80+5x
Y is your total
x is the amount of weeks
I’m not sure bc i did this years ago but u might want to go to ur teacher for some help
Answer:
a) 2L + 2W = 42
b) L = 2W + 3
c) The system is :
2L + 2W = 42
L - 2W = 3
( add the two equations )
3L + (2w - 2w) = 45
3L = 45
L = 45/3
L = 15 ( Length )
L - 2W = 3
15 - 2W = 3
2W = 15 - 3
W = 12/2
W = 6
Scale factor is defined as a number which multiplies or scales some quantity.
The shape of the figure remains same, the image becomes larger or smaller.
If the scale factor is greater than one, then the image is enlarged.
If the scale factor is less than 1 but greater that 0, then the image becomes smaller.
In the above image, AD = 2 units.
It's corresponding side PS = 3 units
Similarly AB = 1 unit and PQ = 1.5 units
Hence , 1 * 1.5 = 1.5
2*1.5 = 3
Hence, the scale factor of the given image is 1.5 ... Answer
