Answer:
5/7
Step-by-step explanation:
We have two points ( 2,-2) and (9,3)
We can find the slope using the slope formula
m = ( y2-y1)/(x2-x1)
= ( 3- -2)/( 9-2)
= ( 3+2)/(9-3)
= 5/7
Answer:
D infitently Many
Step-by-step explanation:
A system of linear equations usually has a single solution, but sometimes it can have no solution (parallel lines) or infinite solutions (same line). This article reviews all three cases. One solution. A system of linear equations has one solution when the graphs intersect at a point.
Tabitha Tidbits costs $7 per bag, and Figaro Flakes is $5.50 per bag.
You need to set up a system of equations. Use "x" for Tabitha Tidbits and "y" for Figaro Flakes, and let the total cost of each trip equal c. Using the equation ax+by=c, substitute the cost of each trip in for c, and the number of bags for each food for a and b respectively. The two equations will be:
3x+4y=43
3x+6y=54
Isolate x in the first equation and you will get:
x=(43-4y)/3
Substitute the above equation for x into the other equation:
3*((43-4y)/3)+6y=54
Isolate y in this equation, and you will get 11/2, which is 5.5
So the cost of one bag of Figaro Flakes is $5.50
Now substitute this into the equation where you isolated x:
(43-4(5.5))/3
You will get x=7, so a bag of Tabitha Tidbits is $7
Answer: Option A
Explanation: The lights that is incident on a mirror will be reflected back as it is a smooth surface and it reflects back the light.
the light will be reflected by the same angle as it was incidented. The angle of incidence can be defined as the angle by which the light ray falls on the surface of the mirror.
The angle by which the light reflects back is known as the angle of reflection. Being a smooth surface light ray is reflected back.
