|y-9|=6
y-9=6
y-9=-6
y=15
y=3
So, y=15,3
add 4n and 5n, which is 9. 9n=-9, and if u divide both sides by nine, n=-1
Answer:
y=-1
x=-3
Step-by-step explanation:
Answer:
a linear equation in x and y
Step-by-step explanation:
The given equation is a linear equation (all variables to the first power) relating the variables x and y. There are an infinite number of values of x and y that will satisfy this equation.
When graphed on an x-y plane, those solution values will fall on a straight line with a slope of 2. It will cross the y-axis at y=32, and the x-axis at x=-16.
√20 the prime factors are 2, 2, 5 so
-2 * √4 *√5
-2*2*√5
-4√5 is the first part ,
now for √125, use prime factorization ,
all prime factors that make up 125 is
5, 5, 5 so √125 can be separated to √25√5 and √25 = 5 so the second part is 5√5.
now -4√5 - 5√5 = -9√5.
therefore answer is -9√5
