so, recall, the function has symmetry when the yielded resulting function resembles the original function, after negativizing the variable(s).
Also recall that minus*plus is minus, and minus*minus is plus.
Answer:
50
Step-by-step explanation:
25% = 0.25
200 * 0.25 = 50
Best of Luck!
Answer:
a rectangle is twice as long as it is wide . if both its dimensions are increased 4 m , its area is increaed by 88 m squared make a sketch and find its original dimensions of the original rectangle
Step-by-step explanation:
Let l = the original length of the original rectangle
Let w = the original width of the original rectangle
From the description of the problem, we can construct the following two equations
l=2*w (Equation #1)
(l+4)*(w+4)=l*w+88 (Equation #2)
Substitute equation #1 into equation #2
(2w+4)*(w+4)=(2w*w)+88
2w^2+4w+8w+16=2w^2+88
collect like terms on the same side of the equation
2w^2+2w^2 +12w+16-88=0
4w^2+12w-72=0
Since 4 is afactor of each term, divide both sides of the equation by 4
w^2+3w-18=0
The quadratic equation can be factored into (w+6)*(w-3)=0
Therefore w=-6 or w=3
w=-6 can be rejected because the length of a rectangle can't be negative so
w=3 and from equation #1 l=2*w=2*3=6
I hope that this helps. The difficult part of the problem probably was to construct equation #1 and to factor the equation after performing all of the arithmetic operations.
Answer:
n = 22
Step-by-step explanation:
Since they are vertical angles they are the same.
Therefore you can put together this equation:
2n - 8 = 36
Add 8 to both sides
2n = 44
Divide by 2
n = 22

the place i got this from tbh i don't understand what you want for an answer but i tried, so here is a website that i got these from i hope it helps you.
Step-by-step explanation:
Evaluate for a= 1/3
3(1/3)+4(1/3) = 7/3
Evaluate for a= 1.5
(3)(1.5)+(4)(1.5)
=10.5
Evaluate for a=
(3)(2)+(4)(2)
=14
