Just substitute the first equation into the second and solve for x: <span><span>32</span>x=−<span>12</span>x+4⟹2x=4⟹x=2</span><span>Now, since y = 3/2 * x, we have y = 3 and we are done.</span>
Lets look at the info we have:-
Ashley found 78 rocks on Monday.
Devin found 45 rocks on Tuesday.
Question:-
How many did they find both days?
The key word for this is "both". So we need to add here. Lets add:-
78 + 45 = 123
So, Ashley and Devin together found 123 rocks.
Hope I helped ya!! xD
Answer:
14
Step-by-step explanation:
-2x^3 - 2x^2 - 4x-2
Let x = -2
-2 (-2)^3 - 2 (-2)^2 -4(-2) -2
Exponents first
-2 (-8) -2 (4) -4(-2) -2
Then multiply
16 -8 +8 -2
Then add and subtract
14
Answer:
(1,18)
Step-by-step explanation:
use a graphing calculator to graph the function
then, graph all the coordinates given and find on that's on the graph
0.016 as a fraction is 16/1000 and in simplest form it is 2/125.
An easy way to figure out the fraction of a decimal is by the decimal places. As we can see, there are four numbers in our decimal (0.016).
The first decimal place = ones
The second decimal place = tenths
The third decimal place = hundredths
The fourth decimal place = thousandths
We stop at the thousandths place, so basically, take 16 and put it over 1000, which looks like 16/1000.
