Answer:
Step-by-step explanation:
From the first sentence x (the number) is 2 more than another number (y). So, x+2=y. The sum of the squares of the two numbers is 42, meaning that
+
=42. First, we square root the ENTIRE equation to get rid of the square. If you do one thing to one side, you have to do it to the other. After this, we have x+2+y=
. Now, we subtract 2 from the other side to isolate the variable. You can isolate either one but normally I go for x. Now we have x+y=
+2. Now, we want to get y to the other side so we subtract it from the left side and the right side which gives us x=-y+
+2. now we know what X is equal to. Now we plug in x for
+
=42, which gives us
+
=42. Now we only have one variable which is what we want. Next, we square root the entire thing to get rid of the squares, which gives us -y+
+4+y=
. I got lost in my work. I must have done something wrong I cant find out. If anyone wants to pick up where I left off go ahead but there's a timer and I have one minute left. I cant finish the problem in a minute. I'm sorry and hopefully I lead you somewhere.
Hey there! I'm happy to help!
To find the number halfway between two numbers, you simply add them and then divide by two.
1.4142133+1.41422=2.8284333
2.8284333/2=1.41421665
That is one number in between these two. Now, we can find the number in between the middle number and the second number. This is another number in between our two numbers.
(1.41421665+1.41422)/2=1.414218325
You could keep on doing this and find tons of numbers in between these two.
Therefore, two numbers between 1.4142133 and 1.41422 are 1.41421665 and 1.414218325.
Have a wonderful day! :D
4z+2(z-4)=3z+11 perform indicated multiplication on left side
4z+2z-8=3z+11 combine like terms on left side
6z/-8=3z+11 add 8 to both sides
6z=3z+19 subtract 3z from both sides
3z=19 divide both sides by 3
z=19/3
z=6 1/3
So there is only one solution when z=6 1/3
Answer:
[-2, ∞]
Step-by-step explanation:
15 - √(x+2)
domain is any value as long as (x+2) is not-negative, since √ of a negative number has no Real solution.
x+2 ≥ 0 ⇒ x ≥ -2
Answer:
(a)
and 
Step-by-step explanation:
Required
Which of a to d has no solution
(a)
and 
We have: 
Sole for m



Divide by 6

So, we have:
and 
implies that: m = -6,-7,-8,-9.....
implies that m = -3,-2,-1,0.....
<em>Hence, there is no solution</em>
