Let x be total hours of battery life. We have been given that battery life of Vera's phone is down to 2/5. So remaining battery life,
We have been also given that it drains another 1/9 every other hour. Now let us substitute our given information into an equation.
Now we will solve for x.
Let us convert 2/5 into minutes. We know 1 hour has 60 minutes.
Therefore, remaining battery life will be 5 hours and 24 minutes.
B=3; C=16; and E=4096.
Using the information we have gives us
We know that:
We know that 2³ = 8, so B = 3.
To "undo" a square root, we square the number; 4²=16, so C = 16.
To "undo" a fourth root, we raise the answer to the fourth power; 8⁴ = 4096, so E = 4096.
I believe the answer is A
Answer: 2 4/5
Step-by-step explanation:
14/3 - 2 2/5
14/3 - 12/5
= 34/15
= 2 4/15
Answer:
The equation would be y = 2x + 3
Step-by-step explanation:
In order to solve this, we first need to find the slope of the line between (-2, 5) and (2, 3). In order to do this, we use the slope formula.
m(slope) = (y2 - y1)/(x2 - x1)
m = (3 - 5)/(2 - -2)
m = -2/4
m = -1/2
Now that we have the original line with a slope of -1/2, we can tell a perpendicular line would have a slope of 2. This is because perpendicular lines have opposite and reciprocal slopes. Now we can use that slope and the given point in point-slope form to get the answer. Be sure to solve for y.
y - y1 = m(x - x1)
y + 7 = 2(x + 5)
y + 7 = 2x + 10
y = 2x + 3
