Answer:
<h2><em><u>-2x</u></em><em><u> </u></em><em><u>+</u></em><em><u> </u></em><em><u>7y</u></em></h2>
Step-by-step explanation:
<em><u>Given</u></em><em><u>, </u></em>
5x– 4у + 3y+8y – 7х
<em>[Bringing like terms together]</em>
= 5x - 7x - 4y + 3y + 8y
<em>[</em><em>Adding</em><em> </em><em>and</em><em> </em><em>subtracting</em><em> </em><em>the</em><em> </em><em>like</em><em> </em><em>terms</em><em>]</em>
= <em><u>- 2x + 7y (Ans)</u></em>
In these questions, they're asking you to express x in terms of the other algebra.
So we can simply solve this by imaging them as real numerical values.
rx - sx + y = b
First shift +y to the other side, change it to negative.
rx - sx =b - y
Factories rx - sx by picking out the common factor x.
x ( r - s) = b - y
Shift (r-s) to the other side, and we're done.
x = b - y / r - s
Therefore, the final answer is
Answer:
A = 314 inches^2
Step-by-step explanation:
We know the diameter of the glass. We need to find the radius
d = 2r
20 = 2r
Divide each side by 2
20/2 = 2r/2
10 =r
To find the area of the glass
A = pi r^2
A = pi * 10^2
A = pi*100
A = 100 *(3.14)
= 314 in^2
Answer:
2
Step-by-step explanation:
You are right as rain. You go to the x axis.
Find x = 3.5
f(3.5) is the y value of x = 3.5
f(3.5) = 2
It might help you a bit if you wrote it as a point (3.5,2)
