Answer: Orange = 5 rupee
Apple = 6 rupees
Step-by-step explanation:
Let the cost of an orange be x
Let the cost of an apple be y
We can form an equation from the question given which will be:
5x + 3y = 43 ......... i
2x + 4y = 34 ......... ii
Multiply equation i by 2
Multiply equation ii by 5
10x + 6y = 86 ........ iii
10x + 20y = 170 ..... iv
Subtract iii from iv
14y = 84
y = 84/14
y = 6
An apple cost 6 rupees
Since from equation ii
2x + 4y = 34
2x + 4(6) = 34
2x + 24 = 34
2x = 34 - 24
2x = 10
x = 10/2
x = 5
An orange cost 5 rupee
Answer:
-1/2
Step-by-step explanation:
Pick two points on the line
(-2,3) and (2,1)
Using the slope formula
m = (y2-y1)/(x2-x1)
= (1-3)/(2 - -2)
= (1-3)/(2+2)
= -2/4
= -1/2
Answer:
x-intercepts: -5 +/-
. y-intercept: 4
Step-by-step explanation:
For x-intercepts use the quadratic equation
Fill in your values:
And solve
For y-intercepts set x=0 and solve. In this case, setting x= 0 gives you y=4.
Answer:
3.528
Step-by-step explanation:
First, you need to determine the scale factor. Divide one side in the larger triangle by the corresponding side in the smaller triangle. For example, 8/2. This would give you a scale factor of 2. Then you can reverse the process with the dimensions you need to get the area. The height of the larger triangle is 3.36, so to find the height of the smaller one, you divide it by 2, or the scale factor, to get the height of the smaller triangle which is 1.68. Next, you can solve for area of triangle using a=bh/2, so 4.2*1.68/2=a = 3.528.
