Answer:

To graph a linear equation in slope-intercept form, we can use the information given by that form.

The equation of a line with slope 3 and y-intercept of 1 is y = 3x + 1 and hence can be graphed.

The slope is the rate of change of the y-axis with respect to the x-axis.

The equation of a line in slope-intercept form is y = mx + b, where

slope = m and y-intercept = b.

We know the greater the absolute value of a slope is the more steeper is its graph or the rate of change is large.

Given, A line has a slope of 3 and a y-intercept of 1.

We know the equation of a line in slope intercept form is, y = mx + b.

Therefore, The equation of a line having a slope of 3 and a y-intercept of 1 is y = 3x + 1.

Step-by-step explanation:

step 1. I assume the question is which of the following equations is parallel to y = -3x + 4

step 2. parallel equation have identical slopes (m)

step 3. 6x + 2y = 15 or y = -3x + 15/2 (solve for y)

step 4. 3x - y = 7 or y = 3x - 7 (solve for y)

step 5. 2x - 3y = 6 or y = (2/3)x - 2 (solve for y)

step 6. x + 3y = 1 or y = (-1/3)x + 1/3

step 7. since y = mx + b we want m to be the same

step 8. the answer is A since they both have the same slope.

The solution to the system of equations are ( 2 , 0 ) and ( 0 , -4 )

Graphs behave differently at various x-intercepts. Sometimes the graph will cross over the x-axis at an intercept. Other times the graph will touch the x-axis and bounce off.

Identify the even and odd multiplicities of the polynomial functions' zeros.

Using end behavior, turning points, intercepts, and the Intermediate Value Theorem, plot the graph of a polynomial function.

The graphs cross or are tangent to the x-axis at these x-values for zeros with even multiplicities. The graphs cross or intersect the x-axis at these x-values for zeros with odd multiplicities

Given data ,

Let the first function be represented as f ( x )

Let the second function be represented as g ( x )

Now , to solve a system of two equations graphically, we need to graph both equations on the same coordinate plane and find their point of intersection. This point represents the solution to the system

So , the point of intersection of the graphs is

A ( 2 , 0 ) and B ( 0 , -4 )

Hence , the solution is A ( 2 , 0 ) and B ( 0 , -4 )

Answer:

  24 cm

Step-by-step explanation:

The perimeter of the left-side triangle is ...

  20 +25 +15 = 60 cm

The scale factor to the right-side triangle is the ratio of corresponding sides. The scale factor of perimeters is the same.

  XZ/LN = perimeter(XYZ)/perimeter(LMN)

  6/15 = P/(60 cm)

  P = (60 cm)(6/15) = 24 cm

The perimeter of ΔXYZ is 24 cm.

Answer:

27 is 50% of 54

Step-by-step explanation:

27 x 2 is 50% x 2

54 is 100%

☁️ Answer ☁️

27 is 50% of 54

We assume, that the number 50 is 100% - because it's the output value of the task.

2. We assume, that x is the value we are looking for.

3. If 100% equals 50, so we can write it down as 100%=50.

4. We know, that x% equals 27 of the output value, so we can write it down as x%=27.

5. Now we have two simple equations:

1) 100%=50

2) x%=27

where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:

100%/x%=50/27

6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 27 is what percent of 50

100%/x%=50/27

(100/x)*x=(50/27)*x - we multiply both sides of the equation by x

100=1.85185185185*x - we divide both sides of the equation by (1.85185185185) to get x

100/1.85185185185=x

54=x

x=54

Answer:

By the Central Limit Theorem, the sampling distribution is approximately normal, with mean 30 and standard deviation 0.1.

Step-by-step explanation:

Central Limit Theorem

The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean [tex]\mu = p[/tex] and standard deviation [tex]s = \sqrt{\frac{p(1-p)}{n}}[/tex]

The batteries produced in a manufacturing plant have a mean time to failure of 30 months with a standard deviation of 2 months.

This means that [tex]\mu = 30, \sigma = 2[/tex]

Sample of 400 batteries. The sampling distribution of is approximately:

So [tex]n = 400, s = \frac{\sigma}{\sqrt{n}} = \frac{2}{\sqrt{400}} = 0.1[/tex]

By the Central Limit Theorem, the sampling distribution is approximately normal, with mean 30 and standard deviation 0.1.

Answer:

It will take 23 years for the account to grow to $7000.

Step-by-step explanation:

Simple Interest

The simple interest formula is given by:

[tex]E = P*I*t[/tex]

In which E is the amount of interest earned, P is the principal(the initial amount of money), I is the interest rate(yearly, as a decimal) and t is the time.

After t years, the total amount of money is:

[tex]T = E + P[/tex]

Carly has a bank account with a balance of $3,575.

This means that [tex]P = 3575[/tex]

The account pays simple interest at a rate of 4.15%.

This means that [tex]I = 0.0415[/tex]

How long will it take for the account to grow to $7000?

[tex]T = 7000[/tex]

The interest is:

[tex]T = E + P[/tex]

[tex]E = T - P = 7000 - 3575 = 3425[/tex]

Now we have to find t.

[tex]E = P*I*t[/tex]

[tex]3425 = 3575*0.0415*t[/tex]

[tex]t = \frac{3425}{3575*0.0415}[/tex]

[tex]t = 23.1[/tex]

Rounding to the nearest year, it will take 23 years for the account to grow to $7000.

Answer:

[tex]\Huge\boxed{A=24.25}[/tex]

Step-by-step explanation:

Herons Formula:

[tex]A=\sqrt{s(s-a)(s-b)(s-c)}[/tex]

where s =  semi perimeter ( perimeter of triangle divided by 2)

and a,b and c = triangle side lengths

Before we can solve we need to calculate the semi perimeter

7 + 13 + 8 = 28

then we divide by 2

28/2=14

so the semi perimeter is 14

now we plug in everything into the formula

[tex]A=\sqrt{14(14-13)(14-8)(14-7)} \\14 - 13=1\\14-7=7\\14-8=6\\A=\sqrt{14(1)(6)(7)} \\14*1=14\\14*7=98\\98*6=588\\A=\sqrt{588} \\\sqrt{588} =24.24871131[/tex]

so we can conclude that the area of the triangle is 24.24871131

our final step is to round to the nearest hundredth

A = 24.25

Answer:

Ela segue esse modelo

f(x) = ax + b

Então, é só substituir os valores de x e de y na Lei de Formação

Ex: quando x=0, y=-1

y= ax+b

-1=a.0+b

b= -1

È onde a reta toca o eixo y, porque x=0

Agora, vamos usar outro par ordenado.

Quando x=2, y=3

3=a.2+(-1)

3=2a-1

3+1=2a

4=2a

a=4/2

a=2

A lei de formação é essa

a= 2; b=-1

f(x)= ax+b

f(x)=2x-1

The answer would be 16

Answer:

a = 12

Step-by-step explanation:

as C^2 = A^2 + B^2

by Pythagoras theorem

so

A^2 = C^2 - B^2

= 13^2 - 5^2

= 169- 25

144

as 12^2 is equal to 144

hence side a is equal to 12

Answer:

[tex]h^2 = p^2 + b^2 \\ {13}^{2} = {p }^{2} + {5}^{2} \\ 169 = {p }^{2} + 25 \\ 169 - 25 = {p}^{2} \\ 144 = {p}^{2} \\ \sqrt{144} = p \\ 12 = p \\ p = 12[/tex]
