Answer:
(4,4)
Step-by-step explanation:
The intersection point of 10y-11x=-4 and -2y+3x=4 is (4,4) on a graph.
Answer:
0
Step-by-step explanation:
slope= gradient
Gradient= Y2 - Y1 / X2 - X1
= -15-(-15)/-7-19 , = -15+15/-7-19
= 0
Formula for surface are: 2(lw+wh+lh) where l is length, w is width and h is height.
Plug in for 1 - 3
1:
2((16)6 + (6)5 + (16)5)
2(96 + 30 + 80)
2(206)
412 ft²
2:
2((13)5 + (5)6 + (13)6)
2(65 + 30 + 78)
2(173)
346 mm²
3:
2((20)4 + (4)15 + (20)15)
2(80 + 60 + 300)
2(440)
880 in²
Step-by-step explanation:
since he threw out tomatoes he has more kilograms of strawberries then tomatoes
First you have to define what a rational and irrational number is and they would be:
a / b, where b can never be 0.
Irrational are the numbers with non-periodic decimals, how the roots are not exact, the number pi, etc.
The student says "the difference of any irrational number and any rational number is rational"
The student's mistake is to use "any" since not any rational number would be the case that fulfills this.
That is, the correct thing is that there is an irrational number and a rational number in such a way that their difference is rational.
