Answer:
x = (-1+√33)/4 or x = (-1-√33)/4
Step-by-step explanation:
Use Quadratic formula with a=2, b=1, c=-4
Answer:
Step-by-step explanation:
Y is equal to 1/5 x + 4 so what you need to do as you need a coordinator or 1/5 is and then you need to move to the right or the left the four
Begin by multiplying everything by 3 to get rid of the fraction. That gives us
. The rule is when you divide by a negative, the direction of the sign changes, so we will end up with
. Because there is a line under the inequality sign, the circle is closed. So your choices are the second, fourth, and sixth.
Answer:
A. f(x) = -0.5(x+3) (x-5)
Answer:
Randomly selecting a six of diamonds - 1 / 52
Randomly selecting a 7, 8, 9 or 10 - 4 / 13
Step-by-step explanation:
There is only 1 six of diamonds in a standard deck of cards. There are 52 cards in a deck, thus the probability of pulling a six of diamonds is 1 in 52.
There are 4 of each card in a deck. so they are 4 7's, 4 8's. 4 9's and 4 10's. And there are a total of 52 cards in a deck. So the probability of pulling a 7,8,9 or 10 are 4 + 4 + 4 + 4 in 52
4 + 4 + 4 + 4 = 16
16 / 52 simplified is 4 / 13 Therefore the is a 4 in 13 chance of pulling a 7 8 9 or 10
The other ones are correct
