A student is trying to solve the system of two equations given below: equation p: a b = 6 equation q: 4a 2b = 19 which of the following steps can be used to eliminate the a term? −1(4a 2b = 19) −4(4a 2b = 19) −4(a b = 6) 4(a b = 6)

Answers

Answer 1

We will use the steps that can be used to eliminate the a term that will be -4(a+b=6). Option C is correct.

What is the system of two equations?

A set of two linear equations with two variables is called a system of linear equations. They create a system of linear equations when evaluated collectively.

The given equation in the problem is;

Equation P: a + b = 6

Equation Q: 4a + 2b = 19

To cancel out the equation q from the equation p.In order to cancel, the term of we has to multiply the term -4 in the equation p.

Hence we will use the steps that can be used to eliminate the a term that will be -4(a+b=6). Option C is correct.

Rounded to the nearest tenth of a centimeter, what is the length of arc lmn? 7.9 cm 10.2 cm 12.6 cm 14.2 cm

Answers

The length of arc LMN is the number of units on the arc

The length of arc LMN is 14.2 cm

How to calculate the length of the arc?

The given parameters are:

Arc LM = 6.3 cmRadius, r = 6 cmAngle MON = 75 degrees

Start by calculating the length of arc MN using:

[tex]MN = \frac{\theta}{360} * 2\pi r[/tex]

So, we have:

[tex]MN = \frac{75}{360} * 2 * 3.14 * 6[/tex]

Evaluate the product

MN = 7.85

The length of arc LMN is then calculated using:

LMN = LM + MN

This gives

LMN = 6.3 + 7.85

Evaluate the sum

LMN = 14.15

Approximate

LMN = 14.2

Hence, the length of arc LMN is 14.2 cm

Find the coordinates of the turning point for the equation of the graph below
y=x^2– 16x +39
=

Answers

Answer:

x = 8 - sqrt(y + 25)

Step-by-step explanation:

Step-by-step explanation:

comparing given equation with ax^2+bx+c;

a=1   b=-16   c=39

now,

x coordinate of vertex = -b/2a

                                      = 16/2*1

                                     = 8

again,

y coordinate of vertex = (8)^2-16(8)+39

                                       =-25

Therefore, the turning point is (8,-25).

a 2014 mustang originally costs $25000.00 and depreciates at a rate of 8% per year. What is the cost of the car after 7 years?

Answers

$11,000 will bet the cost in 7 years

Given:

Original cost: $25,000

Depreciation rate: 8%

Term: 7 years

Formula for Depreciation:

A = C ( 1 - ( r ) (t) )

A = Future Value

C = Original Cost

r = rate

t = term

Solution:

Substitute the given values to the formula for depreciation.

A = $25,000( 1 - ( 0.08)(7))

A = $25,000( 1 - .56 )

A = $25,000(0.44 )

A = $11,000

Answers

The mean of the data is 1.31, while the mean absolute deviation is 2.56.

What is the Mean Absolute Deviation?

The mean is the average of a data set, while the mean absolute deviation is the average distance of the each data point from the mean.

Given the data:

3,2,2,5,4,1,3,4,1,0,3,2,1,1,6,3

Find the Mean:

Mean = (3 + 2 + 2 + 5 + 4 + 1 + 3 + 4 + 1 + 0 + 3 + 2 + 1 + 1 + 6 + 3)/16 = 41/16 Mean = 2.5625

Find the Mean Absolute Deviation:

Mean abosolute deviation = (3 - 2.5625) + (2 - 2.5625) + (2 - 2.5625) + (5 - 2.5625) + (4 - 2.5625) + (1 - 2.5625) + (3 - 2.5625) + (4 - 2.5625) + (1 - 2.5625) + (0 - 2.5625) + (3 - 2.5625) + (2 - 2.5625) + (1 - 2.5625) + (1 - 2.5625) + (6 - 2.5625) + (3 - 2.5625) / 16

Mean abosolute deviation = 21/16 = 1.3125

Therefore, the mean of the data is 1.31, while the mean absolute deviation is 2.56.

The length of a rectangular garden is 2 m greater than the width. The area is 80 m^2. Find the dimensions of the garden.

The width of the garden is ___m.
The length of the garden is ___m.

Answers

Answer:

Length of rectangle = 10 mWidth of the Rectangle = 8 m

Step-by-step explanation:

Given :-

Length of a Rectangular garden is 2m greater than the width .Area of garden = 80 m²

To Find :-

Dimensions of the garden

Solution :-

Let's assume:

Width of the rectangle = xLength of the rectangle = x + 2

We know that,

Area of rectangle = Length × Width

↠ (x)(x + 2) = 80

↠ x² + 2x - 80 = 0

↠ x² + 2x - 80 = 0

↠ x² + 10x - 8x - 80 = 0

↠ x(x +10) -8 (x + 10) = 0

↠ (x-8) (x + 10) = 0

↠ x = 8 or -10

↠ x = 8

Hence,

Width of the rectangle = x = 8 mLength of the rectangle = x + 2 = 10 m

Answer:

Given:-

Length of rectangular garden is 2m longer than its widthArea of Rectangular garden is 80m²

To Find :-

Dimensions of Rectangular garden

Solution:-

Let the width be x and length be x + 2

According to the question ,

Area = 80m²

putting the known values ,

(X)(X+2) = 80m

x² +2x - 80= 0

x² +10x-8x -80m= 0

x(x + 10) - 8(x+10) = 0

(x-8) = 0 ; (x+10) = 0

X = 8 ; X = -10

As dimensions can not be negative so , X = 8

Length = X + 2 ; 10 m

Width = X ; 8 m

Answers

So, the length of the side adjacent to angle β is approximately 17.15 cm. triangle Therefore, the closest option is 16.7 cm.

What is a triangle?

A triangle is a closed, double-symmetrical shape composed of three line segments known as sides that intersect at three places known as vertices. Triangles are distinguished by their sides and angles. Triangles can be equilateral (all factions equal), isosceles, or scalene based on their sides. Triangles are classified as acute (all angles are fewer than 90 degrees), good (one angle is equal to 90 degrees), or orbicular (all angles are higher than 90 degrees) (all angles greater than 90 degrees). The region of a triangle can be calculated using the formula A = (1/2)bh, where an is the neighbourhood, b is the triangle's base, and h is the triangle's height.

sin(β) = opposite/hypotenuse

[tex]hypotenuse^2 = adjacent^2 + opposite^2\\17.5^2 = adjacent^2 + opposite^2\\306.25 = adjacent^2 + opposite^2\\[/tex]

opposite = sin(β) x hypotenuse = 0.292 x 17.5 = 5.095 cm

[tex]306.25 = adjacent^2 + 5.095^2\\306.25 - 5.095^2 = adjacent^2\\294.81 = adjacent^2\\[/tex]

√294.81 = adjacent

So, the length of the side adjacent to angle β is approximately 17.15 cm. Therefore, the closest option is 16.7 cm.
