Answer:-25+-12
Step-by-step explanation:so I made x value as 5 so I multiplied -5x5 and it's -25 then I multiplied -4x-7 and that's -12 so the equivalent expression for my way is -25+-12
Answer:
Step-by-step explanation:
cos(20°) = (14/2)/x
x = 7/cos(20°) ≈ 7.45
Step-by-step explanation:
Area of trapezium=(b1+b2)*h/2 ( as given in figure)
b1=30in.
b2=36in.
h=20in.
Area=(30+36)*20/2
=660inches²
Inverse of the function 2x-6y=1
To get the inverse of the function, first, interchanged
the variables such x will be y and y will be x.
<span>(1) </span><span> 2y – 6x = 1</span>
Then, find the value of y in the new equation,
<span>(2) </span><span> 2y – 6x + 6x = 1 + 6x</span>
2y
= 1 + 6x
<span>(3) </span>(1/2)(2y)
= (1 + 6x)(1/2)
<span> y = (1 + 6x) / 2</span>
<span>The reverse of the function
is y
= (1 + 6x)/2.</span>
