Answer:
A) y will increase by 4 unit.
B) y will decrease by 20 units
Step-by-step explanation:
Given equation that shows relation between x and y.

A) If x is increased by 4 units
New value of y = 


So, change in y = new value of y- original value of y



Thus, the value of y will be increased by 4 units.
B) If x is decreased by 5 units
New value of y = 


So, change in y = new value of y- original value of y



= -20
Thus, the value of y will be decreased by 20 units.
Answer:
x = 75
Step-by-step explanation:
We can write this as a proportion
27 45
--------- = --------
45 x
We can use cross products to solve
27 x = 45 *45
Divide each side by 27
27 x/27 = 45*45 /27
x = 75
1) X=159
2) BCD=103
3) DCH=89
im pretty sure
Answer:
yes
Step-by-step explanation:
-8x-2y<6
put in x and y and see if it is less than 6
-8(3) -2(2) <6
-24 -4 <6
-28 <6
yes
it is a solution
