A 90 degree counter-clockwise rotation is being done on the black figure to get the red figure.
The algebraic rule for a 90 degree counter-clockwise rotation is
For instance, the point C = (0,1) moves to C' = (-1,0), which is shown in the graph given and also you can use the rule above to get the same coordinates. The other points A,B and D follow the same rule.
Side note: the rotation is centered at the origin (0,0). This point is fixed.
Answer:
income=2*expenses-100
Step-by-step explanation:
income=a*expenses+b
a:slope
a=(income of 1 - income of 0)/(expenses of 1 - expenses of 0)
=(10-0)/(55-50)=10/5=2
income=2*expenses+b
for product 0
income=0
expenses=50
》0=2*(50)+b
b=-100
income=2*expenses-100
Answer:
12?
Step-by-step explanation:
wouldnt the width just be either 12 or 16? because theres nothing else to multiply by
Answer: M is the coefficient
Step-by-step explanation:
Answer:
the desired equation is y = (-1/5)x - 5.
Step-by-step explanation:
Parallel lines have the same slope. Here that slope is -1/5.
Let's use the slope-intercept form of the equation of a straight line:
y = mx + b
We know this new line passes through (-10, -3). Substitute -3 for y in y = mx + b, as well as -10 for x and -1/5 for m:
-3 = (-1/5)(-10) + b and solve for b:
-3 = 2 + b. Then b = -5, and the desired equation is y = (-1/5)x - 5.
