y = mx + b
When a function is reflected over the y-axis, the b (2) stays the same but the slope (m) changes to its opposite sign.
since the slope is negative in this equation, it will become positive.
so the new fuction will be
y = 5x + 2
Answer:
152
Step-by-step explanation:
6840 divided by 45 is 152
Answer:Okay I'm really confused
Step-by-step explanation:
For Erin, the graph shows 10 pounds of sugar are used for every 30 cups of tea.
For Lucia, we can let x=3 and we find 3 pounds of sugar are used for 10·3 = 30 cups of tea.
For the same number of cups of tea (30), Erin uses 10 pounds of sugar and Lucia uses 3 pounds of sugar.
Erin uses sugar at a higher rate.
It is equivalent to 7(6) + 14
Step-by-step explanation:
- Step 1: Solve 7(a + 2) when a = 6
⇒ 7 (6 + 2) = 7 × 8 = 56
- Step 2: Find its equivalent
7(6) + 14 = 42 + 14 = 56
