Explanation :

slope intercept form

y=mx+b

y= -3x+4

slope is also m

b is the y-intercept

Answer:

a(n-1)+d

d=5

The anser is A

Answer:

division, I mostly use it and I find it easy

Answer:

the equation is in form

y=mx+b where

m=slope

and

b=y-int (the y value for the vertex)

first we look to see what the y value is for the point where x=0 and we can see that it is 5 so b=5

then we look at the slope, slope it the amont of units up then to the side are needed to reach the next point, in this case the line goes up 1 then to the right 1 so the slope is 1/1 (1) so the full equation is

y=x+5

Step-by-step explanation:

Answer:

Step-by-step explanation:

To write an equation that is perpendicular to a given line, take the negative reciprocal of the given slope. the given slope is 4/3, so the negative reciprocal is -3/4.

Using slope-intercept form of a linear equation, y=mx+b substitute in -3/4 for "m" the slope.

y=-3/4x+b

Now you need to "b" the y-intercept using the given point (-4,-1). Substitute the values in the equation. -1=-3/4(-4)+b simplify

                           -1= 3 + b    subtract 3 for both sides

                           -4=b

         substitue -4 for b.   Now you have    y= -3/4x - 4    this is your answer.

Answer:

Part 3: 9 Dogs

Step-by-step explanation:

It says that the ratio they want you to put it in is dogs/students, so dogs are x, and students are y, so if there are 4 students for every dog, 36 students would require 9 dogs

And if the roles were switched it would be students x, dogs y, and there would be 9 students for 36 dogs :D

Answer:the original price is $680

Step-by-step explanation:

1/4(x)=170

4×1/4(x)=4×170

x=$680

The original price of the nightstand is $680.

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

Given that, Krystal bought a nightstand on sale for $170, which was one-fourth of the original price.

Let the original price of nightstand be x.

Now, 1/4x =170

x=170×4

x=$680

Therefore, the original price of the nightstand is $680.

Answer:

D. 60

Step-by-step explanation:

Since the question stated that the number of marbles given out to his 6 friends were equal, we are certain that the total number of marbles is a factor or multiple of 6.

The only other assumption here is the number of marbles given has to be whole number. This means we just have to go through the answer choices and pick the one that is a multiple of 6.

A. 15 - This is wrong as 15 is not a multiple of 6.

B. 33 - This is wrong as 33 is not a multiple of 6.

C. 56 - This is wrong as 56 is not a multiple of 6.

D. 60 - This is CORRECT as 60 is a multiple of 6.

If Jorge gives each of his friends 10 marbles each, it would bring the total number of marbles to be 60.

9514 1404 393

Answer:

  9

Step-by-step explanation:

  (f ◦ g)(3) = f(g(3))

Each of the coordinate pairs for g correspond to ...

  (x, g(x))

Then g(3) can be found by looking for the pair that has 3 in the first location. That ordered pair is ...

  (3, 4)

so we know that g(3) = 4.

Now, we know that f(g(3)) = f(4). This tells us to look for the ordered pair in the f relation that has 4 as its first value. That ordered pair is ...

  (4, 9)

so we know that f(4) = 9.

__

In summary, ...

  (f ◦ g)(3) = f(g(3)) = f(4) = 9

Answer:

The solution set is {x : x ∈ R, x > 3} ⇒ C

Step-by-step explanation:

Let us solve the question

∵ x - 5 > -2

→ Add 5 to both sides of the inequality

∴ x - 5 + 5 > -2 + 5

∴ x > 3

→ By using the first rule above

∴ The solution set is {x : x ∈ R, x > 3}

Step-by-step explanation:

Answer:

2 seconds later

Step-by-step explanation:

Since the required equation is lacking, let the equation modeled by the height be expressed as y = -16t² + 64

The ball hits the ground at y =0. Substitute y = 0 into the expression and find t;

Since y = -16t² + 64

0 =  -16t² + 64

16t² = 64

t² = 64/16

t² = 4

t = ±√4

t = 2 and -2

Time cannot be negative, hence the ball hits the ground 2 seconds later.

Note that the equation used was assumed. Similar solution can be applied for any given equation.

Answer:

consecutive interior angles equal 180 not equal to each other

Step-by-step explanation:

Answer:

6x− 1 0 = 4 + 4 0

6x-10=4x+40

6x−10=4x+40

Solve

1

Add  

1 0

10

10

to both sides of the equation

6 − 1 0 = 4 + 4 0

6x-10=4x+40

6x−10=4x+40

6 − 1 0 + 1 0 = 4 + 4 0 + 1 0

6x-10+{\color{#c92786}{10}}=4x+40+{\color{#c92786}{10}}

6x−10+10=4x+40+10

Simplify

Add the numbers

Add the numbers

6 = 4 + 5 0

6x=4x+50

6x=4x+50

Subtract  

4 4x 4x

from both sides of the equation

6 = 4 + 5 0

6x=4x+50

6x=4x+50

6 − 4 = 4 + 5 0 − 4

6x{\color{#c92786}{-4x}}=4x+50{\color{#c92786}{-4x}}

6x−4x=4x+50−4x

Step-by-step explanation:

well we know that STUV is a parallelogram (given)

so by properties of a parallelogram we know that opposite sides are congruent (in other words equal)

so we have that

VU=TS

and we know that VU=123.8 cm (given)

so TS=123.8

Answer:

Independent-samples t-test.

Step-by-step explanation:

We are looking for the appropriate design for testing the significance of the difference between the means.

Now, there is a parametric test known as the Independent Samples t Test and what this test does is that it compares the mean of two independent groups in order to find out whether there is statistical evidence that the related population mean is significantly different.

Thus, the test to be used here is Independent-samples t-test.

Answer:

The answer would be option 2) 51 miles/3 gallons.

Step-by-step explanation:

First, every 17 miles needs 1 gallon. If you add 17 more miles, it'll be 34 miles and you'll need a 2nd gallon, so you can already eliminate options 3 and 4. If you add another 17 miles and a gallon, it'll give you 51 miles 3 gallons. Option 1 would not be the answer because if you did 3/51, you'll get a whole different answer in decimals. So the only other option to choose from is option 2.

Answer:

(2+3i)(1-2i)  = (8-i)

Step-by-step explanation:

The given complex number is :

Z = (2+3i)(1-2i)

We need to find the product of the complex number

[tex]Z=2(1)+2(-2i)+3i(1)-6i^2\\\\=2-4i+3i-6i^2[/tex]

We know that, [tex]i^2=-1[/tex]

[tex]Z=2-i-6(-1)\\\\=2-i+6\\\\=8-i[/tex]

Hence, the product of the complex number is (8-i).
