Vlad spent 20 minutes on his history homework and then completely solved x math problems that each took 2 minutes to complete. W
liq [111]
<span>y = 2x + 20. The answer is A. Explanation: Vlad spends a known amount of time on his history homework (20). On top of it, he also spends an unknown amount of time on solving a number of math problems (x). Each problem takes two minutes to solve, so the amount of time that he spends solving math problems is 2*x or 2x. In total (y), Vlad spends 20 + 2x amount of time on his homework. So y = 2x + 20, where y is clearly greater or equal to 20 and x is greater or equal to 0.</span>

There are 10 coconuts at-the base of your tree. The coconuts are falling off the tree at a rate of 6 coconuts per week. Assume t
Sphinxa [80]

Answer: y = 6x +10.

After 7 weeks there will not be any coconut on the tree.

Step-by-step explanation: Given initial number of coconuts under the tree = 10 coconuts.

The rate of falling of coconuts each week = 6 coconuts per week.

Let us assume number of weeks be x and y be total number of coconuts after x weeks.

So, total number of coconuts after x weeks would be = Rate of falling of coconuts × number of weeks + Initial number of coconuts.

Therefore,

y = 6x +10.

a) y = 6x +10

Let us graph the linear equation with y-intercept 10 and slope rise/run = 6/1.

b) Total number of coconuts after x weeks = 52.

Plugging y=52 in above equation, we get

52 = 6x+10.

Subtracting 10 from both sides, we get

52-10 = 6x=10-10

42 = 6x.

Dividing both sides by 6, we get

42/6 = 6x/6

7 = x.

Therefore, after 7 weeks there will not be any coconut on the tree.

PLS HELP MEE ASAP 1 MIN LEFT HELPP!!!!!!!!!

Answer: BC = 5.83

Step-by-step explanation:

Luckily, the triangle is placed on the graph nicely so we can count the legs of the triangle:

AB = 5

AC = 3

BC = ?

To find BC, we can simply use the Pythagorean Theorem:

a^{2}+b^{2}=c^{2}

5^2 + 3^2 = c^2

25 + 9 = c^2

34 = c^2

Now square root to find c, or BC.

\sqrt{34}=\sqrt{c^{2} }

c = 5.83 (rounded by nearest hundredth)
