Answer:
x=5
y=7
Step-by-step explanation:
y = x+2 so plug that in the next equation as y
so it be --> 5x+(-4)(x+2)= -3 now use distributive property
(-4 times x)+(-4 times 2)= -4x+-8 replug that back in
5x-4x+-8 = -3 subtract your x
1x = x so ---> x+-8 = -3 now to get rid of -8 we have to add 8 to it
x= -3 but whatever you do to one side u do to the other so u have to add 8 to -3---> so it be x=5
now take that x=5 and plug it in to your first eqaiuton to get y
y=5+2 ---> y =7
Find the volume of the icicle using the formula V = PI x r^2 x h/3
Volume = 3.14 x 4.5^2 x 120/3
Volume = 3.14 x 20.25 x 40
Volume = 2543.4 cubic mm.
Now divide the total volume by the drip rate:
2543.4 / 75 = 33.9 minutes.
The answer is D.
Answer:
the midpoint is (4,3)
Step-by-step explanation:
Answer:
u=95
Step-by-step explanation:
To solve this problem we need to isolate 'u' variable using properties of equation.
Lets multiply by -9 the whole equation
u - -23=-8*9
Remember keys features of algebra:
- * - = +
- * += -
+ * - = -
+ * + =+
So, our equations becomes>
u+23=-72
Lets now subtract 23 to both sides
u-23=-72-23
We have u=95
