Let's use a for number of days when he shot 50 shots and b for number of days when he shot 100 shots.
We have:
a + b = 20
We also know that he shot total of 1250 shots:
50a + 100 b = 1250
We have two equations. We can solve them for a and b. Let's rearange first equation for a:
a= 20 - b
We insert this into second equation:
50 * (20 - b ) + 100b = 1250
1000 - 50b + 100b = 1250
50b = 250
b = 5
a = 20 - 5
a = 15
Mark shot 100 shots on 5 days.
Answer:
8/5
Step-by-step explanation:
(y2-y1) / (x2-x1)
10-2 = 8
8-3 = 5
8/5
Step-by-step explanation:
x/3+x/6=7/2
We simplify the equation to the form, which is simple to understand
x/3+x/6=7/2
Simplifying:
+ 0.333333333333x+x/6=7/2
Simplifying:
+ 0.333333333333x + 0.166666666667x=7/2
Simplifying:
+ 0.333333333333x + 0.166666666667x=+3.5
We move all terms containing x to the left and all other terms to the right.
+ 0.333333333333x + 0.166666666667x=+3.5
We simplify left and right side of the equation.
+ 0.5x=+3.5
We divide both sides of the equation by 0.5 to get x.
x=7
Answer:
Step-by-step explanation:
In the equation of a straight line (when the equation is written as "y = mx + b"), the slope is the number "m" that is multiplied on the x, and "b" is the y-intercept (that is, the point where the line crosses the vertical y-axis).
Answer: y=-x+7
Step-by-step explanation:
Answer:
Your given points: (9,-2)and (1,6)
x1=9
y1=-2
x2=1
y2=6
Step-by-step explanation:
To find slope take the points you got from graph and put it into the equation y2-y1/x2-x1
6-(-2)/1-9=6+2/1-9=8/-8=-1
SLOPE IS m=-1
Then take that slope u got and plug into this equation to find equation of the line
y-y1=m(x-x1)
y-(-2)=-1(x-9)
y+2=-x+9
-2. -2
