Slope=

Equation in point slope form

Answer:

[tex]y=-4x+1[/tex]

Step-by-step explanation:

We have been given two points on the line, so:

[tex]\textsf{let}\:(x_1,y_1)=(-1,5)[/tex]

[tex]\textsf{let}\:(x_2,y_2)=(1,-3)[/tex]

Calculate the slope using the slope formula:

[tex]\textsf{slope}\:(m)=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{-3-5}{1-(-1)}=-4[/tex]

From inspection of the graph, it appears that the y-intercept (where the line crosses the y-axis) is at (0, 1).  However, just to be sure, use the point-slope form of linear equation.

Point-slope form of linear equation:  [tex]y-y_1=m(x-x_1)[/tex]

(where m is the slope and (x₁, y₁) is a point on the line)

[tex]\implies y-5=-4(x-(-1))[/tex]

[tex]\implies y-5=-4x-4[/tex]

[tex]\implies y=-4x+1[/tex]

Therefore, the equation of the line in slope-intercept form is:

[tex]y=-4+1[/tex]

When there's a linear relationship, the least-squares method to determine the regression coefficients b0 and b1 will be y = 0.750 + 0.50x.

The meaning of the slope, b1, in this problem is the coefficient of x which is the slope. Here, b1 = 0.50. It implies that one unit change in x will be 0.5 unit change in y.

To predict the mean tear rating when the plate gap is equal to 0 goes thus:

y = 0.75 + (0.05 × 0)

y = 0.75 + 0

y = 0.75

Lastly, the relationship between the plate gap and the tear rating is a positive one.

The difference is 33 -12 = 21 years. Jacob will be half Todd's age in 21 -12 = 9 years, when Jacob is 21 and Todd is 42.

Answer:

A. and D.

Step-by-step explanation:

Hey there!

In order to to find the point at which these two equations intersect at, you need to first rewrite the equations if needed so that they are in the form:

[tex]y=mx+b[/tex]

or

[tex]y=ax^2+bx+c[/tex]

The first equations needs to be rewritten

[tex]3x+5=y+4x[/tex]

make [tex]y[/tex] by itself

[tex]3x+5-4x=y[/tex]

Simplify LHS

[tex]y=-x+5[/tex]

Now we have it in slope-intercept form

Looking at the equation, we can tell that the slope of the line is [tex]-1[/tex] and the y-intercept is 5

Now you can graph this equation easily (image down below)

The second equation is already in form so there is no need to rewrite anything

We can go straight to graphing (image down below)

Now plot both equations on the same graph (image down below)

Answer:

D  4+p=24

Step-by-step explanation:

So P stands for Paul & how much he spent.

Dan spent $24 at the store & he spent $4 more than Paul, so Paul only spent $20.  So P = $20

So which equation would work if you substituted $20 for P?

4 + P = 24

4 + 20 = 24

Total number of chips

Probability of a blue chip

The subsequent blue has same probability as the chip is replaced.

Probability of two blue chips is

Answer:

[tex]\sf \dfrac{9}{169}[/tex]

Step-by-step explanation:

The bag has:

⇒ Total number of chips = 6 + 13 + 7 = 26

Probability Formula

[tex]\sf Probability\:of\:an\:event\:occurring = \dfrac{Number\:of\:ways\:it\:can\:occur}{Total\:number\:of\:possible\:outcomes}[/tex]

Probability of choosing a blue chip from the first draw:

[tex]\implies \sf P(Blue)=\dfrac{6}{26}[/tex]

As the chips are replaced, the probability of choosing a blue chip from the second draw is the same as the first.

Therefore, the probability of taking out a blue chip in both draws is:

[tex]\begin{aligned}\implies \sf P(Blue)\:and\:P(Blue) & = \sf \dfrac{6}{26} \times \dfrac{6}{26}\\\\& = \sf \dfrac{6 \times 6}{\26 \times 26}\\\\& = \sf \dfrac{36}{676}\\\\& = \sf \dfrac{36 \div 4}{676 \div 4}\\\\& = \sf \dfrac{9}{169}\end{aligned}[/tex]

Answer:

It's A.

Step-by-step explanation:

Because whatever goes into the absolute value symbol, it'll turn out positive. And real numbers could only be positive.

The total amount of money that Stephen would pay his uncle is equal to $10,600.

Mathematically, simple interest is calculated by using this formula:

I = PRT

Where:

Given the following data:

Interest rate = 2% = 0.02.

Principal = $10,000.

Time = 3 years.

Substituting the given parameters into the formula, we have;

I = 10000 × 0.02 × 3

I = $600.

Amount of balance;

A = I + P

A = 600 + 10,000

A = $10,600.

Answer:

That statement is true, but you do not always need the two.

Let's say that we had a problem, given the radius is 5, and we have to find the diameter.

First step is to define A

[tex]A = \pi r^2[/tex]

Second, redefine r as the actual radius to avoid confusion.

[tex]r = 5[/tex]

Third, set up an equation with the given values where you are multiplying pi by the radius.

[tex]\pi r^2 = \pi *r^2[/tex]

Fourth but not least, get the actual value.

[tex]\pi * r^2 = 79[/tex] rounded to nearest whole number

Answer:

x = 8.98782862707

Step-by-step explanation:

Base on the given we can infer that we are solving for x:

Given equation:

1000x+27x+5.5=9236

Combine similar terms

1027x + 5.5 = 9236

Subtract both side by 5.5

1027x + 5.5 = 9236

             -5.5      -5.5

-------------------------------------

1027x = 9230.5

Now divide both sides by 1027x

9230.5 / 1027

x = 8.98782862707

Neither the laws of sines nor the law of cosines can be used to solve the triangle. The correct option is the third option - neither law can be used

The law of sines is written as

[tex]\frac{sinA}{a}=\frac{sinB}{b}= \frac{sinC}{c}[/tex]

Where a,b, and c are sides of any given triangle and A,B, and C are the angles.

This law is used when we are given either

The law of cosines is written as

a² = b² + c² -2bc cosA, or

b² = a² + c² - 2ac cosB, or

c² = a² + b² -2ab cosC

Where a,b, and c are sides of any given triangle and A,B, and C are the angles.

This law is used when we are given either

Now, for triangle xyz, which the measures of angles X,Y, and Z are known, neither law can be used to solve the triangle.

Hence, neither the laws of sines nor the law of cosines can be used to solve the triangle. The correct option is the third option - neither law can be used

Answer:

2√3

Step-by-step explanation:

root 27

= √27

= 3√3

12 upon root 3

= 12 / √3

= ( 12 / √3 ) x ( √3 / √3 )

= ( 12 x √3 ) / ( √3 x √3 )

= 12√3 / 3

= 4√3

6 upon √3

= 6 / √3

=  ( 6 / √3 ) x ( √3 / √3 )

= ( 6 x √3 ) / ( √3 x √3 )

= 6√3 / 3

= 2√3

root 3 = √3

root 3 + root 27 - 12 upon root 3 + 6 upon root 3
