The answer is 12/4 because the ratio is 4/5 and we would multiply 4 to which is 12
Is this helped please award me brainliest because I only need one more for the next rank
Answer:
The function increasing ⇒ 3 ≤ x ≤ 6 answer C
Step-by-step explanation:
∵ The vertex of the parabola is (3 , -6)
∴ The minimum value = -6 at x = 3
∵ The left part of the parabola is decreasing because the value of y decreased from 3 to -6 when 0 ≤ x ≤ 3
∵ The right part of the parabola is increasing because the value of y increased from -6 to 3 when 3 ≤ x ≤ 6
∴ The function is increasing at interval 3 ≤ x ≤ 6

Answer:
Step-by-step explanation:
$1800 is spent on a washing machine. This number never changes, so we just need to add that to our annual total
$89 is spent every year. This means that this number needs to be with our variable, x, as it is dependent on the number of years that occur. When we put these two things together, we get the following equation:
<span>241 of the 25¢ notebook
107 of the 38¢ notebook
1) Let x = no. of 25¢ notebooks sold and y = no. of 38¢ notebooks sold
2) Total notebooks sold: x + y = 348
3) Revenue from the notebooks: 0.25x + 0.38y = 100.91
4) Substitute one equation to the other and solve for a single variable (either x or y)</span>
