Answer:
-1/5
Step-by-step explanation:
i don't know for sure but that seems like the one that would make the most sense
2x² + 5x - 3 = 0, 2) 3x² + 14x - 5 = 0, 3) (7 - 3x)(x + 2) = 4
Answer:
x=12
Step-by-step explanation:
To make these 2 lines perpendicular to each other, one of their angles must be equal to 90 degrees.
Therefore, we can set up an equation with one of the angles:
7x+6=90
7x=84
x=12
The information of the other angle is useless in this case, but we can use it to check by plugging in 12 for x, and seeing if it equals to 90:
8*12-6=96-6=90
Therefore, x=12.
Answer:
<h3>y = 1</h3>
Step-by-step explanation:
Correct question
The points ( 2,4) and (5,y) lie on the same line. If the slope of the line is --1, what is the value of y
The formula for calculating slope of a line is expressed as;
m = y2-y1/x2-x1
Substitute the given point
y - 4/5-2 = -1
y-4/3 = -1
y-4 = -3
y = -3+4
y = 1
Hence the value of y is 1
Answer:
it is just 64-18=48
Step-by-step explanation:
you have to just keep 64 the same and do the 9*2. And sum those outcomes.
