Answer:
56 is 70% of 80 students.
Step-by-step explanation:
70% = 0.7
56 divided by 0.7 = 80
Vertex point: (1, -4)
X-intercepts: (-1, 0) , (3, 0)
Y-intercept: (0, -3)
Axis of symmetry: x = 1
This function will create a parabola that opens upwards. I’m not entirely sure what I was supposed to answer. Hopefully this covered it. I’ll attach an image of the parabola in case I missed anything.
0.84(20)=$16.80
700/100=7
7(1.02)=$7.14
$7.14+16.80=$23.94 in total
Answer:
Explanation:
Given 4x + 6y - 10x + 13y = 11
If (1, 1) is a solution, then substituting x = 1 and y = 1 into the left hand side of the equation gives 11.
Doing this, we have:
4(1) + 6(1) - 10(1) + 13(1)
= 4 + 6 - 10 + 13
= 13
The answer is true I have had this question before
