A line goes through the point (0, -7) with a slope of -4.
If you write the equation in standard form, what is the coefficient of x?

Answers

Answer:

[tex]\huge\boxed{\sf The\ co-efficient\ of\ x\ is\ -4.}[/tex]

Step-by-step explanation:

Slope = m = -4

Y-intercept = c = -7 ( Because that is the point where x = 0 )

Equation:

[tex]\sf y = mx+c\\\\y = -4 x+(-7)\\\\y = -4x-7[/tex]

So, The co-efficient of x is -4.

What is y = 1/4x + 4 written in standard form?

Answers

Answer:

1x+ -4y= -16

Step-by-step explanation:

y= 1/4x + 4

subtract 1/4x from both sides

-1/4x + y= 4

multiply both sides by -4

1x -4y= -16

Hi, how to do question 10:)?

Answers

Step-by-step explanation:

For the cubic function to be an increasing function, dy/dx > 0 for all real values of x.

dy/dx

= d/dx [4x³ + 4px² + 16x - 9]

= 12x² + 8px + 16.

We have 12x² + 8px + 16 > 0.

=> 3x² + 2px + 4 > 0,

where a = 3, b = 2p and c = 4.

For the quadratic function to have a range that is always positive, the discriminant must be less than 0.

(in order to have no real roots)

We have b² - 4ac < 0.

=> (2p)² - 4(3)(4) < 0

=> 4p² - 48 < 0

=> p² - 12 < 0

=> p² < 12

=> -√12 < p < √12

=> -2√3 < p < 2√3.

That was a very long process but hopefully you understand all of it!

EFGH is a parallelogram. Find the measure of EG. parallelogramefghmsidesw7 The measure of EG is .

Answers

Answer: EG = 80

Step-by-step explanation: A parallelogram is a quadrilateral with opposite sides parallel to each other.

The diagonals of a parallelogram bisect each other, which means, using the figure as example:

EJ = JG

So, to determine EG, first find w:

[tex]4w+4=2w+22[/tex]

[tex]2w=18[/tex]

w = 9

Substituting:

[tex]EJ=4w+4[/tex]

[tex]EJ=4(9)+4[/tex]

EJ = 40

Since each segment has the same measure:

EG = 2EJ

EG = 2(40)

EG = 80

The measure of EG is 80 units

A system of equations is given below:

x + 2y = 7
-3x + 4y = 9

Nicole says she would multiply the first equation by 3 and add the two equations together to eliminate the x's. Michael says he would multiply the first equation by 2 and add the two equations to eliminate the y's.

Who is correct? and explain why.

Answers

Answer:

Nicole is correct

Step-by-step explanation:

by multiplying the first equation by 3 it becomes:

3x + 6y =21

this can cancel the -3x in the second equation when adding them together

Answer:

Nicole is correct, since when she multiplied by 3, she cleared the x's, since one x was already negative, and the other one was positive. Michael is incorrect since when he multiplied by 2, he didn't realize that both y's were positive, so they didn't clear.

Step-by-step explanation:

Let's see what will happen if we do what Nicole says:

x+2y=7

-3x+4y=9

multiply the first equation by 3 on both sides

3(x+2y)=7(3)

3x+6y=21

-3x+4y=9

now let's add them.

10y=30

We can see that the x's are cleared, since one x is positive and the other is negative.

Now let's try what Michael says.

x+2y=7

-3x+4y=9

multiply first equation by 2

2(x+2y)=7

2x+4y=7

-3x+4y=9

now let's add

-x+8y=16

the y's aren't eliminated, since both of them are positive.

Nicole is correct, since one x is positive and another was negative, and when opposite numbers are added together, they  cancel out and equal zero.

Step-by-step explanation:

first trem a1 = 38

common difference d = 200

nth term = a1 + (n-1(d

= 38 + 200(n-1)

= 200n - 162

The explicit formula for arithmetic sequences is 200n - 162.

What is an arithmetic sequence?

The sequence in which every next number is the addition of the constant quantity in the series is termed the arithmetic progression.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

The given sequence is 38, 238, 438, 638,

first trem a₁ = 38

Common difference d = 200

nth term = a₁ + (n-1(d

nth term = 38 + 200(n-1)

nth term = 200n - 162

The mean height is 3.2 feet and thestandard deviation 0.6 feet. A… ... A forest ranger has data on the heights of a large growth ... mately what fraction of the trees should we expect to be.

The  fraction of the trees that is between 4.0 and 4.4 feet is 7%

The z score is used to determine by how many standard deviations the raw score is above or below the mean. The z score is given by:

[tex]z=\frac{x-\mu}{\sigma}[/tex]

x is the raw score, μ is mean and σ is standard deviation

Given that μ = 3.2, σ = 0.6, hence:

[tex]For\ x = 4:\\\\z=\frac{4-3.2}{0.6} =1.33\\\\\\For\ x = 4.4:\\\\z=\frac{4.4-3.2}{0.6} =2[/tex]

From the normal distribution table, P(4 < x < 4.4) = P(1.33 < z < 2) = P(z < 2) - P(z < 1.33) = 0.9772 - 0.9082 = 7%

The  fraction of the trees that is between 4.0 and 4.4 feet is 7%

Which property will give the step:

[tex]TY \cong AR\\[/tex]

Looking at the options:

We see that Symmetric property states that if a = b then b= a

Same is the case with the question.

We have :

A rectangle has a length of (2x-7) and a width of (x+5) perimeter

Answers

Answer:

6x - 4

Step-by-step explanation:

Perimeter is equal to double the length plus double the width, and if you use this to find perimeter, you would get that the perimeter = 2(2x-7)+2(x+5), which simplifies to 4x - 14 + 2x + 10, which simplifies to 6x - 4. That means that the rectangle's perimeter is 6x-4.

Answers

Answer:

One hosta = $ 12 , One shrub = $ 5

Step-by-step explanation:

Let;

x = hostas

y = shrubs

Emily spent $132 on 6 hostas and 12 shrubs.

6x + 12y = 132 ........................................ (i)

Chelsea spent $213 on 14 hostas and 9 shrubs

14x + 9y = 213 ........................................ (ii)

From (i)

12y = 132 - 6x

y = 11 - 0.5x  ........................................ (iii)

substitute (iii) into (ii)

14x + 9 (11 - 0.5x) = 213

14x + 99 - 4.5x = 213

9.5x = 114

x = $ 12

Substitute value of x in (iii)

y = 11 - 0.5(12)

y = 11 - 6 = $ 5

length = area = width. Which expression can Alicia use in the programming to represent the
length of each placemat?
А
9x - 25
B
9x + 25
C 45x2 - 66x - 144
D 9x2 - 14.2x - 30

Answers

Answer:

A

Step-by-step explanation:

The expression for the width of rectangular placemats is (9x - 25) units.

Given that, the area of rectangular placemats=45x²-70x-150.

What is the area of a rectangle?

The area of a rectangle (A) is the product of its length 'a' and width or breadth 'b'. So, the area of the rectangle = (a × b) square units.

Now, 45x²-70x-150=(5x + 6)×b

⇒b=45x²-75x-150/(5x + 6)

⇒b=(5x + 6)(9x - 25)/(5x + 6)

⇒b=(9x - 25)

Therefore, the expression for the width of rectangular placemats is (9x - 25) units.
