Answer:
Because if you give the power of 2 to all of them you get a different number
1. 20 squared+ 21 squared = 841
Answer to number 1
2)Same for this. 4^2+5^2= 9^2
3)a^2+b^2 = ab^2 because since a and b are different letters/variables you cannot combine them therefore it is just ab.
4) (-1)^2 = 1 because -1 multiply by -1 again you would get positive 1. Next you do 1+0^2 = 1. Because 0^2 is just 0 because 0times 0 =0 so 1+0 = 1

Answers
Answer:
(x2 , y2) = (22,50)
Step-by-step explanation:
Given:
m1 : m2 = 1:4
(x1 , y1) = (7 , 5)
(X ,Y) = (10 ,14)
Find:
(x2 , y2)
Computation:
X = (m1x2 + m2x1) / (m1+m2)
10 = [(1)(x2) + (4)(7)]/(1+4)
10 = [x2 + 28]/5
22 = x2
Y = (m1y2 + m2y1) / (m1+m2)
14 = [(1)(y2) + (4)(5)]/(1+4)
14 = [y2 + 20]/5
70 = y2 + 20
50 = y2
(x2 , y2) = (22,50)

Answer:
See attached
Step-by-step explanation:
Given function:
y= –3x + 4To graph the line we need two points
One of the easy points is the y-intercept:
(0, 4)Another point can be taken depending on the slope. With the slope of -3, we select x = 2 and find its y- coordinate:
y = -3(2) + 4 = -6 + 4 = -2So we have points
(0, 4) and (2, -2)Plot these points and connect with the line and we are done.

The sum of two numbers is 10. Their difference is 6. What are the two numbers?
Answers
Answer: 8 and 2
Step-by-step explanation:
this is simple, since we only have 10 numbers to work with. i just kept experimenting with numbers until i got one that had a difference of 6. no strategy, just brain power. hope this helps! xoxo
Answer:
So negatove numbers are gonna be impossible becuase we know that the highest we can go is -10+20=10 but it’ll give a whole different difference when subtracted.
And it can’t be greater then 10 becuase if you do add them it won’t be 10
SO it has to be between 1-10
So what equals 10?
5/5
2/8
8/2
6/4
4/6
3/7
7/3
Now 5 and 5 is out cause if subtracted its 0
2/8 and 8/2 works, if added you get 10 but when subtracked the way for 8/2 from left to write it’ll give 6 which is the only one which will give.
final answer the two numbers are 8 and 2
what is the length of the diagonal C

Answers
Answer:
d = √389
Step-by-step explanation:
to find c we use 15 and 8 into the formula of "a^2 + b^2 = c^2" which is 17. Now we use 17 and 10 as a and b to find c in the formula which is d.
a^2 + b^2 = c^2
10^2 + 17^2 = x^2
100 + 289 = x^2
389 = x^2
√389 = √x^2
√389 = x

If a varies jointly as b and c,
and a=6 when b=2 and a=3.
Find the variation constant and
the equation of variation.
Answers
Given:
a varies jointly as b and c.
a=6 when b=2 and a=3.
To find:
The variation constant and the equation of variation.
Solution:
a varies jointly as b and c.
[tex]a\propto bc[/tex]
[tex]a=kbc[/tex] ...(i)
Where, k is the constant of proportionality.
a=6 when b=2 and a=3.
[tex]6=k(2)(3)[/tex]
[tex]6=6k[/tex]
[tex]\dfrac{6}{6}=k[/tex]
[tex]1=k[/tex]
The value of k is 1.
Putting k=1 in (i), we get
[tex]w=1xy[/tex]
[tex]w=xy[/tex]
Therefore, the variation constant is 1 and the equation of variation is [tex]w=xy[/tex].

The student council raised $2,790 during its annual fundraiser. The money was shared equally among the Events Committee, the Sports Committee, and the Sunshine Committee. a. The Sports Committee wants to use its share of the money to purchase t-shirts. If each t-shirt costs $12, what is the greatest number of t-shirts the Sports Committee can purchase? ANSWER NOW PLEASE!!!!
Answers
Answer:
77
Step-by-step explanation:
$2790 is shares equally between 3 committees. each committee would get - $2790 / 3 = $930
If a shirt costs $12 and the Sports Committee gets $930, the committee would get $930 / $12 = 77.5
The committee cannot get half a shirt, so the greatest number of shirt that can be purchased is 77

Given the lengths of sides XY and XZ as shown in triangle XYZ below, what is the length of side YZ?
a. 5√13
b. 12
c. √194
d. 18
e. 5√5
Answers
Answer:
YZ = 12
Step-by-step explanation:
From the question given above, the following data were obtained:
Length of XZ = 13
Lenght of XY = 5
Lenght of YZ =?
The length of YZ can be obtained by using pythagoras theory since the figure is a right angle triangle. This can be obtained as follow:
XZ² = XY² + YZ²
13² = 5² + YZ²
169 = 25 + YZ²
Collect like terms
169 – 25 = YZ²
144 = YZ²
Take the square root of both side.
YZ = √144
YZ = 12
Therefore, the length of YZ is 12
