Step-by-step explanation:
Given the equation
Putting x = -2 in the equation
y = 2x + 3
= 2(-2) + 3
= -4 + 3
= -1
(x, y) = (-2, -1)
Putting x = -1 in the equation
y = 2x + 3
= 2(-1) + 3
= -2 + 3
= 1
(x, y) = (-1, 1)
Putting x = 0 in the equation
y = 2x + 3
= 2(0) + 3
= 0 + 3
= 3
(x, y) = (0, 3)
So the table chart of x and y values will be:
x y
-2 -1
-1 1
0 3
The graph of is attache below.
This is simple. Just add the x and y values of each ordered pair to see which ones equals 2.
The answer is (-4, 6), (0, 2), (4, -2)
Answer:
a = 2
b = 4
c = 8
Step-by-step explanation:
Remember the relationship:
First, in "a" we have:
a)
then in the next ones, we can use the result that we obtained in the part a:
b)
Now we can do exactly the same in c:
c) where first we need to know that:
2*2*2*2 = 4*4 = 16
then:
2^4 = 16
then:
Now let's solve the problem:
Answer:
Savings in March: $60
Savings in April: $60 + 150% of $60=$60 +$90=$150
Step-by-step explanation:
Liam adds another 150% of the original amount to his savings. So, his total amount does not change but the amount increases by $90 (150% of $60).
Using the Pythagorean theorem, we can say that a^2 + b^2 = c^2, where A is 8, b is 15, and s is c.
8^2 + 15^2 = s^2
64 + 225 = s^2
289 = s^2
17 = s
Hope this helps :)
