Midpoint Formula is
((x1+x2)/2, (y1+y2)/2)
Answer:
(14,-1)
Step-by-step explanation:
okay so first you need to use the "x=4y+10" in the first equation.
Rewrite as
3(4y+10) +11y=7
Distribute the 3(4y+10)
Rewrite as
12y+30
You'll have the equation
12y +30 +11y= 7
Subtract the 7 from both sides
12y+30+11y-7= 0
Combine like terms
23y+23=0
the best thing to do here is divide the equation by 23.
23/23 = 1
you'll have
y + 1 = 0
this simplifies to
y= -1
use this y value to solve for x
the easiest way to do this is start with the equation
x = 4y +10
Substitute the y for -1
x = -4(-1) +10
x = 4 +10
x = 14
the solution point is
(14,-1)
Answer: C.V=C1.V1 +C2.V2
Step-by-step explanation: C=(C1V1 + C2V2)/V -> C=(20%.V+25%V)/2V-> C=22,5%
Answer:
2,3,5,6,9,10
Step-by-step explanation:
To do this, we can look at how each value divides into 90. If it produces a whole number, they will be consider to be divisible

This means 4 is the only value that is not divisible into 90
Answer:
= 225
= 64
= 289
+
+ 
= 225 + 64 = 289
289 = 289
Hence its a right angled triangle
