What is the y-intercept Of the function Represented by the table of values belowX -2 1 2 4 7 y 15 6 3 -3 -12
Given:
The table of values.
To find:
The y-intercept of the given function.
Solution:
The table of values represents a linear function because the rate of change is constant.
Consider any two points from the given table. Let the two points are (-2,15) and (1,6). Then the equation of the linear function is
[tex]y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]
[tex]y-15=\dfrac{6-15}{1-(-2)}(x-(-2))[/tex]
[tex]y-15=\dfrac{-9}{1+2}(x+2)[/tex]
[tex]y-15=\dfrac{-9}{3}(x+2)[/tex]
[tex]y-15=-3(x+2)[/tex]
Adding 15 on both sides, we get
[tex]y=-3x-6+15[/tex]
[tex]y=-3x+9[/tex]
Putting x=0, we get
[tex]y=-3(0)+9[/tex]
[tex]y=0+9[/tex]
[tex]y=9[/tex]
The y-intercept is 9. Therefore, the correct option is C.
Answer: this is correct

The following distribution is not a probability distribution because
x
-5
-4
-3
-2
P(x) 0.08 0.23 0.44 0.12 0.24
A) The values of x are negative
B) The probability values are not increasing
C The probability values do not add to 1
D) The probability values are not discrete
Answer:
C The probability values do not add to 1
Step-by-step explanation:
Given
The above table
Required
Why is it not a probability distribution
In probability, the sum of all probabilities must equal 0.
But in this case:
[tex]\sum P(x) \ne 0[/tex]
Because:
[tex]0.08 + 0.23 + 0.44 + 0.12 + 0.24 \ne 0[/tex]
[tex]1.11 \ne 0[/tex]
Hence:
Option (c) answers this question

Factor the quadratic expression x2-19x+88 (x+__)(x+__) ^ Where the answer would go
Answer:
(x+8)(x+11)
Step-by-step explanation:
When you factor a quadratic by the form:
[tex]x^{2} + bx + c[/tex]
you are looking for two numbers, 'q' and 'r', which ADD to 'b' and MULTIPLY to 'c'.
In this case, some example numbers that multiply to 88 are:
±1, ±2, ±4, ±8, ±11, ±44, ±88.
Since they must add to 19, then you can figure out through some trial and error that the numbers are 8 and 11.
8*11 = 88
8+11 = 19
So, the answer is (x+8)(x+11)
A bin contains seven red chips, nine green chips, three yellow chips, and six blue chips. Find the probability of drawing a yellow chip, not replacing it, and then choosing a blue chip.
Group of answer choices
a.) 3/100
b.) 9/625
c.) 3/200
d.) 18/625
Answer:
a) 3/100
Step-by-step explanation:
There are 25 total chips
P(Yellow) = 3/25
With no replacement P(Blue) = 6/24 = 1/4
Multiply 3/25* 1/4= 3/100
The diagram represents a dilation with a center at P. If the scale factor of e dilation is K, which statement about the diagram is true?
Answer:
C is correct. If the scale factor is greater than 1, the image is an enlargement. The segment UT could be an enlargement of the segment ST.
Step-by-step explanation:
A. If > 1, then the image of could be .
B. If 0 < < 1, then the image of could be . ( If the scale factor is between 0 and 1, the image is a reduction )
C. If > 1, then the image of could be .
D.If = 2, then the image of is itself.
A is not correct. If the scale factor is between 0 and 1, the image is a reduction.
B is not correct. If the scale factor is between 0 and 1, the image is a reduction.
C is correct. If the scale factor is greater than 1, the image is an enlargement.
D is not correct. If the scale factor is 1, the figure and the image are congruent.
The dilation factor for triangle PST (K₁) is less than that of triangle PUV (K₂).
What is scale factor? How it is used in Dilating sides?Scale factor tells us by how much one quantity is greater than the other. It is denoted by K. Mathematically → K = a/b.Rewriting, we get → a = Kb.If a side length [a] of any 2 - D figure is dilated by a scale factor of [k], then the length of new side will be [Ka].Given is a diagram that represents a dilation with a center at {P}. The scale factor of the dilation is {K}.
The dilation factor for triangle PST (K₁) is less than that of triangle PUV (K₂).
Therefore, the dilation factor for triangle PST (K₁) is less than that of triangle PUV (K₂).

Answer:
B'(6, 6) ; C'(12, 6)
Step-by-step explanation:
The points are not labeled so I'm going to assume the points are as follows:
A(3, 9)
B(3, 3)
C(6, 3)
In order to dilate with a scale factor of 2, simply multiply the x and y coordinates by 2.
B(3, 3) ⇒ B'(6, 6)
C(6, 3) ⇒ C'(12, 6)
Given the graphs of f(x) = -x + 2 and g(x) = 5x – 4, what is the solution to the equation f(x) = g(x)?
A) -4
B) 0
C) 1
D) 2
Answer:
c) 1
Step-by-step explanation:
f(x) = g(x)
-x+2 = 5x-4
+x +x
2 = 6x -4
+4 +4
6 = 6x
(divide both sides by 6)
1 = x

Can someone please help me. I’m not quite understanding this problem
Answer:
A=3
B=8
C=2
D=5
Step-by-step explanation:
hope this helps
Answer:
okay, so to get A you'll have to add 2 and 1 and get three. So, A equals 3. then to get B you will add 3 and 5 because A equals 3 and that will give you 8. so, B equals 8. To get D you will add 2 and 3. that will make D equals 5. to get C you will get 2. because 3 plus two equals five and because 1 plus 2 equals 3
