X^2+ 14x = -33
Quadratic equation
x=-3
x=-11
because
x(x+14)=-33
so if x = -11 it will be 3*-11
and if x= -3 it will be -3*11
Answer:
x = -3, -11
Step-by-step explanation:
First, factor
Get all the terms on one side by adding 33 to both sides:
[tex]x^2 + 14x + 33 = 0[/tex]
now, you want to find two numbers that add up to 14 and multiply to 33.
those numbers would be 3 and 11.
so you can then make it:
[tex](x + 3)(x+11)=0[/tex]
you know that either x + 3 or x + 11 = 0,
so you can say:
x + 3 = 0
x = -3
ork
x + 11 = 0
x = -11
so x = -3, -11.

Gerald is conducting an experiment with 3 possible outcomes. Kasey is conducting an experiment with 20 possible
outcomes.
Which statement best relates the possible outcomes to the number of trials needed to produce results
similar to their predicted outcomes?
A) Gerald will need to conduct more trials than Kasey because there are fewer possible outcomes in his experiment.
B)Gerald will need to conduct fewer trials than Kasey because there are fewer possible outcomes in his experiment.
C)Gerald will need to conduct more trials because he needs to make up for the difference in the number of possible
outcomes.
D)Gerald will need to conduct fewer trials because experimental and theoretical results in experiments with small
numbers of possible outcomes are the same.
Answer:
B/2
Step-by-step explanation:
Gerald will need to conduct fewer trials than Kasey because there are fewer possible outcomes in his experiment. Then the correct option is B.
What are samples?A sample is a group of clearly specified components. The number of items in a finite sample is denoted by a curly bracket.
Gerald is conducting an experiment with 3 possible outcomes. Kasey is conducting an experiment with 20 possible outcomes.
The best relates the possible outcomes to the number of trials needed to produce results similar to their predicted outcomes will be
Kasey will need to conduct more trials because the number of samples is more.
Gerald will need to conduct fewer trials because the number of samples is less.
Then the correct option is B.

First, the triangle is dilated by a scale factor of 1/3 about the origin. Then the triangle is reflected over the x-axis. Finally, the triangle is translated left 3 units and up 2 units.
Answer:
[tex](\frac{1}{3}x - 3,-\frac{1}{3}y+2)[/tex]
Both triangles will be similar
Step-by-step explanation:
See comment for complete question.
Given
Let the coordinates of the triangle be T(x,y)
First transformation: Dilation by 1/3
The new points will be:
[tex]T' = \frac{1}{3}(x,y)[/tex]
[tex]T' = (\frac{1}{3}x,\frac{1}{3}y)[/tex]
Second: Reflection over the x-axis
When a point (x,y) is reflected over the x-axis, the new point is (x,-y).
So, we have:
[tex]T'' = (\frac{1}{3}x,-\frac{1}{3}y)[/tex]
Third: Translation 3 units left and 2 units up.
When a point (x,y) is translated b units left and h units up, the new point is (x - b,y+h).
In this case:
[tex]b = 3[/tex] and [tex]h = 2[/tex]
So, we have:
[tex]T''' = (\frac{1}{3}x - 3,-\frac{1}{3}y+2)[/tex]
Hence, the coordinate of the new triangle will be: [tex](\frac{1}{3}x - 3,-\frac{1}{3}y+2)[/tex]
Additionally, both triangles will be similar because all the transformation done are rigid transformations i.e. Dilation, Reflection and Translation

Answer:
#5- 7.8 hours #6- $5.25
Step-by-step explanation
Question #5- 7.8 hours
First we have to find the speed. If the speed was constant we should be able to divide the miles by the time to find the speed. So 239.82 divided by 4.2. This would leave us with a speed of 57.1 mph. So to finish the question, we have to take what we know and divided it by the speed. If he drives 445.38 miles at the same speed of 57.1 mph it would take him 7.8 hours. I got this answer by dividing the miles by the speed. 445.38 divided by 57.1. Which got us our time, 7.8 hours.
Question #6- $5.25
Okay so we know that the chips cost .75 cents a bag, and he got two bags. So if we take .75 and multiply it by two we get 1.50. So the chips alone cost $1.50. We can take the price of the chips and subtract it from the total price. 22.50-1.50. 21. Now we have just the prices of the sandwiches. If we take the total price of the sandwiches and divide it by the number of sandwiches bought, we get $5.25. So each sandwich cost $5.25 each.

k+ 6 ≥ 19, if k = 11
Answer:
Then it would be the other way around 19 ≥ k + 6
Wait for more responses if needed.
The given Inequality is correct when 19 ≥ k + 6.
What is inequality?Inequality compares "two values, showing if one is less than, greater than, or simply not equal to another one".
Given k + 6 ≥ 19 if k = 11
11 + 6 ≥ 19 substitute k = 11
17 ≥ 19 here Inequality is False.
Hence, 19 ≥ k + 6.

Three red,ten white, five blue and two green counters are put into a bag, and one is picked at random. Calculate the probability that it is:
i) a white counter
ii) a red counter
iii) Are the outcomes equally likely?
Answer:
(i) 1/2
(ii) 3/20
Step-by-step explanation:
(i) given total number of white counters = 10
total outcomes = 20 (3+10+5+2)
so it's 10/20
by simplifying it we get 1/2
(ii) given total number of red counters = 3
so it's 3/20

The positive GCF of -9y and -3 is 3.
3x
= -9y
3X
3
The factored expression is?
Answer:
3 x -3y = -9y
3 x -1 = -3
The factored expression is 3(-3y - 1)
Step-by-step explanation:
All you have to do is -9y / 3 = -3y and -3 / 3 = -1, then put those numbers in parentheses. All of that is multiplied by 3.
The reason is because if you distributed the 3 it would become:
3 * -3y + 3 * -1 = -9y - 3
