If the line is perpendicular to "y= -3x +2" its slope must be the opposite reciprocal of the -3. The opposite reciprocal of -3 is 1/3 so that is the slope of your line.
Now utilize y=mx+b and your point (3,-1) to find the y intercept.
-1=1/3(3)+b
b=-2
Equation: y=1/3x-2
Answer:
(x-9)(x-5)
Step-by-step explanation:
x²-5x-9x+45
x(x-5)-9(x-5)
(x-9)(x-5)
<em>Paco could buy 1/2 a yard, 5/8 yard, 3/4 yard, 7/8 yard, 1 yard, 1 1/8, so fourth since these fractions are all greater than 1. </em>
Answer:
B
Step-by-step explanation:
the question says -12x ≤ -72.the sign ≤ means less than or equal to. so we will divide both sides by -12 to get the value of x. and that wil give us x ≤ 6, the sign did not change because we used a sign common to both sides to divide it. that is slso the reason why we had a positive value.
Answer:
k = 45
The angles are 45 , 45, 90
Step-by-step explanation:
The sum of the angles of a triangle are 180
45+ k+2k = 180
Combine like terms
45+3k = 180
Subtract 45 from each side
45+3k-45 = 180-45
3k = 135
Divide by 3
3k/3 = 135/3
k =45
The angles are 45, k,2k
The angles are 45 , 45, 90
