Answer:
x-intercept: (9,0)
y-intercept: (0,-9)
Step-by-step explanation:
The x-intercept and y-intercept is the point at which a line intersects the x-axis and y-axis, respectively. All points on the x-axis have a y-value of 0, while all points on the y-axis have an x-value of 0. Thus, to find the x and y intercepts, substitute 0 for one of the variables in the equation, then solve for the other.
1) To find the x-intercept, substitute 0 for y. Then, isolate x.
So, the x-intercept must be (9,0).
2) To find the y-intercept, substitute 0 for x. Then, isolate y.
So, the y-intercept must be (0,-9).
Answer:
The mixture contains 80% water and 20% alcohol.
Step-by-step explanation:
Given:
Total Amount of mixture = 60 oz
Amount of alcohol in the mixture = 12 oz
We need to find the percentage of water and percentage of alcohol in the mixture.
Solution:
First we will find the amount of water in mixture.
Now we know that;
Total Amount of mixture is equal to sum of Amount of alcohol in the mixture and amount of water in mixture.
so we can say that;
amount of water in mixture = Total Amount of mixture - Amount of alcohol in the mixture
amount of water in mixture =
Now we will find the Percentage amount of water.
Percentage amount of water can be calculated by dividing amount of water in mixture by Total Amount of mixture and then multiplying by 100.
framing in equation form we get;
Percentage amount of water =
Percentage amount of alcohol =
Hence The mixture contains 80% water and 20% alcohol.
Answer:
Maximum profit is $87 when 3 blenders and 11 mixers are produced.
Step-by-step explanation:
let blender is represented by and and mixer by
.
total time to deliver parts = 24 hrs
total time to assemble = 30 hrs
time taken by each blender to deliver parts = 1 hr
time taken by each mixer to deliver parts = 2 hr
time taken by blenders in final assembling= 2 hr
time taken by mixers in final assembling = 3 hr
Each blender produced nets the firm= $7
Each mixer produced nets the firm= $6
Using this all data linear system of equation will be:
profit function:
Coordinate points obtained from (1) are (0,12) and (24,0)
Coordinate points obtained from (2) are (0,10) and (15,0)
plotting these on graph
points lying in feasible region are:
A(0,0)
B(0,10)
C(3,11)
D(12,0)
substituting these points in (3) to find the maximum profit:
for A (0,0)
z = 0
for B (0,10)
z = 60
for C (3,11)
z = 87
for D (12,0)
z=84
So maximum profit is $87 when 3 blenders and 11 mixers are produced.
