Answer:
it would be a triangle
Step-by-step explanation:
Answer:
C
Step-by-step explanation:
25 (2c-1)
(25 x 2c) - (25 x 1)
50c - 25
Answer:
y=-2x+160
Step by Step:
The equation of a line can be determined using the point slope formula:
y-y1=m (x-x1)
To make a substitution, we must ensure we have the correct information. The question gives:
y1=60
x1=50
y=1/2x+10 This is the formula of a line that is perpendicular to the one we are trying to find.
It tells us that the gradient of the perpendicular line is 1/2. The gradient of the line we are trying to find can be found using m1×m2=-1 because we know that when lines are perpendicular, the product of their gradients must equal 1
So if we replace m1 with 1/2
1/2×m2=-1
m2=-2
We now have all the relevant information to make a substitution:
y-60=-2 (x-50)
expand brackets
y-60=-2x+100
rearrange to get in the form y=mx+b
y=-2x+160
Answer:
12
Step-by-step explanation:
3w = w + 8
-w -w
2w = 8
w = 4
4 + 8 = 12
Answer:
1% of 1200 is 12, so to find this we multiply 12 until we get 150
150/12 = 12.5
12.5%
