Help!!!! Cause this is my bro work

The answer is 12 − 10

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.

i believe it is c or b

Step-by-step explanation:

Answer:

y=2x+2

Step-by-step explanation:

2 is the y intercept and you get the formula y=mx+b so b=2 and m is the slope which is rise over run to get 2.

Answer:

$532

Step-by-step explanation:

Hey There!

So to solve this problem the first thing that we want to do is find the cost of 1 ball

To do so we divide the total cost of 10 balls by 10

280/10=28 so each ball cost 28

now to find the cost of 19 balls we multiply the cost of 1 ball by 19

18x28=532

thus meaning 19 balls cost $532

Answer:

$532

Step-by-step explanation:

We need to find the cost of 1 ball and then multiply it by 19, here is the math:

280/10=28

Now we know that 28 is the cost of 1 ball.

28 x 19=532

The cost of 19 balls is $532

Answer:

P(X > 127.1) = 0.0233

Step-by-step explanation:

We are given;

Population mean; μ = 125 mm

Sample mean; x¯ = 127.1 mm

Sample size; n = 44

Standard deviation; σ = 7 mm

Formula for test statistic is;

z = (x¯ - μ)/(σ/√n)

z = (127.1 - 125)/(7/√44)

z = 2.1/1.0553

z = 1.99

From z-table attached;

P(X > 127.1) = P(z > 1.99) = 1 - 0.97670 = 0.0233

Answer:

x=6

Step-by-step explanation:

I would look at this triangle and notice that x can be solved by setting up a ratio.

I generally put the short side of the triangle on the top and the long side on the bottom

4/x = x/9

You then cross multiply to get 36=x^2, or +-6=x

A length of a triangle cannot be negative, so we are left with the answer x=6

Answer:

Step-by-step explanation:

(2,11)(-3,6)

-3-2/6-11

-5/-5

m=1

y=mx+b

11=1(2)+b

11=2+b

b=9

y=x+9

b—> 9

Slope: 1 (The y value increases the same amount as the x.)

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).

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:

the area should be 3/4

Step-by-step explanation:

Answer:

48 ways

Step-by-step explanation:

Treat the vowels as 1 unit by itself which in this case is A & E.

Imagine filling in 4 slots:

_ _ _ _ , since A&E are treated as 1 letter.

Thus we have 4 ways to fill in 1st slot, 3 ways for 2nd, 2 for 3rd and 1 for last.

which makes 4 * 3 * 2 * 1 = 24.

However, do note A&E can be arranged as AE or EA meaning,

we need to multiply by 2 factorial.

24 * 2 = 48

Step-by-step explanation:

Given

Line is [tex]y=\frac{1}{2}x+5[/tex]

Put [tex]x=0\ \text{to get y}[/tex]

[tex]\Rightarrow y=\frac{1}{2}\times 0+5\\\Rightarrow y=5[/tex]

i.e. line passes through [tex](0,5)[/tex]

Now, put [tex]y=0\ \text{to get x}[/tex]

[tex]\Rightarrow 0=\frac{1}{2}x+5\\\Rightarrow x=-10[/tex]

i.e. line passes through [tex](-10,0)[/tex]

Join these two points to get the line
