Graph these numbers and then connect at the end.
3. y (6,-3). x (2,-4) z (5,-7)
4. U (5,4). T (5,1) S (1,0) V(-3,4)
i hope these help.
You have r^2 = 64 and want to find the square root of 64, which we'll call r.
√(r^2) = r = plus or minus √64
or: r = plus or minus 8
Answer: n-4(32.5) > 300;n > 430tep-by-step explanation:
Zack wants to make a profit of more than $300 for painting 4 identical rooms. That is
Profit > $300
the profit he makes is equal to the amount he is paid - the cost of supplies. The cost of supplies is $32.50 for each room. That is
n - 32.5 and
P + 32.5 × 4
Where 4 = number of rooms
P + 130
n-4(32.5) > 300;n > 430tep-by-step explanation:
given that Zack wants to make a profit of more than $300 for painting 4 identical rooms. That is
Profit > $300
Then, the profit he makes is equal to the amount he is paid minus the cost of supplies. The cost of supplies is $32.50 for each room. That is
n - 32.5 and
P + 32.5 × 4
Where 4 = number of rooms
P + 130
The minimum profit = 300 + 130 = $430
n-4(32.5) > 300;n > 430 430
If you mean "factor over the rational numbers", then this cannot be factored.
Here's why:
The given expression is in the form ax^2+bx+c. We have
a = 3
b = 19
c = 15
Computing the discriminant gives us
d = b^2 - 4ac
d = 19^2 - 4*3*15
d = 181
Note how this discriminant d value is not a perfect square
This directly leads to the original expression not factorable
We can say that the quadratic is prime
If you were to use the quadratic formula, then you should find that the equation 3x^2+19x+15 = 0 leads to two different roots such that each root is not a rational number. This is another path to show that the original quadratic cannot be factored over the rational numbers.
Answer:
C)
Step-by-step explanation:
Since theyre the same measure all you would need is the missing variable.
