If two line are perpendicular. The multiply of their slopes are equal to -1.
First line's slope is: -1/2x because if the line equation is form of y=ax+b a is slope.
Let say second line's slope is m
m.-1/2=-1 so m=2
y=ax+b is general form of linear function/equation. (a=slope)
y=2x+b
If this line passes through the point (2,-2),if we write -2 to y and 2 to x, the equation becomes true.
-2=4+b
b=-6
Thus,
y=2x-6 is true answer.
Answer:D
Step-by-step explanation:
factorise 2x²-16x+32
x²-8x+16
(x-4)²
factorise 4x²-2x-20
2x²-x-10
2x²+4x-5x-10
2x(x+2)-5(x+2)
(2x-5)(x+2)
solving for (f/g)(x)
(x-4)²/(x+2)÷(2x-5)(x+2)/(x-4)²
(x-4)²/(x+2)*(x-4)²/(2x-5)(x+2)
(x-4)⁴/(2x-5)(x+2)²
Answer:
0.090
Step-by-step explanation:
In the number 0.496, the number 9 is in the hundredths place.
0.4<u>9</u>6
The value of 9 in 0.496 is 9 hundredths, or 0.090.
Hope this helps.
I think it's 42 since 7x6=42
Step-by-step explanation:
First, note the place you want to round to. It says “the nearest ten thousandth” which is the fourth digit to the right of the decimal point. There is a 3 is in the ten thousandths place. Next, look at the digit to the right of the 3. Here’s how you do it. I’m too lazy.
