Answer:
it must increase by 5 units
Step-by-step explanation:
Answer:
slope : -5/2
y-inter : 2
Step-by-step explanation:
-5x - 2y = -4
-2y = 5x - 4
-2y/-2 = 5x/-2 - 4/-2
y. = -5/2x + 2
Answer: "C"
roots would make the function "0"
so just plug in the numbers...
with a + 12 you need minuses to cancel out...
B & C can not be the answer...
A is -i -3 + 4i - 12 which also is not 0
C is : 8i -12 -8i +12 WHICH DOES = 0
Step-by-step explanation:
Let x=Don's present age
2x=Chris's present age
next year:
<span>x+1=Don's age
</span><span><span>2x+1=Chris's age
(x+1)+((2x+1)=4(x-1) (next year the sum of their ages will be four times as much as Don's age last year.)
x+1+2x+1=4x-4
x=6
2x=12
Don's present age=6
Chris's present age=12 </span><span>
</span></span>
Answer: x=5,y=9
Step-by-step explanation:
Add the equations in order to solve for the first variable. Plug this value into the other equations in order to solve for the remaining variables.
