Answer:

y = -1

Step-by-step explanation:

The standard form of equation of a line is y = mx+b

m is the slope

b is the y intercept

Get the coordinate of the point of interception of the line 2x - y = 9 and 3x - 7y = 19

Make y the subject of the formula in both expressions

For 2x  - y = 9

- y = 9- 2x

y = 2x - 9

Similarly for 3x - 7y = 19

-7y = 19 - 3x

7y = 3x - 19

y = 3/7 x - 19/7

Equating both expressions

2x - 9 = 3/7 x - 19/7

Multiply through ny 7

14x - 63 = 3x - 19

14x - 3x = -19 + 63

11x = 44

x = 44/11

x = 4

Since y =2x - 9

y = 2(4) - 9

y = 8-9

y = -1

Hence the coordinate of intersection is at (4, -1)

Get the equation of the line passing through (-3, -1) and (4, -1)

Slope m = -1+1/4+3

m = 0/7

m = 0

Get the intercept

Substitute m = 0 and (-3, -1) into y = mx+b

-1 = 0(-3) + b

-1 = b

b = -1

Get the required equation

Recall that y = mx + b

y = 0x + (-1)

y = -1

Hence the required equation is y = -1

Answer:

demanded;

the price of another good demanded

Step-by-step explanation:

Cross price elasticity of demand measures the responsiveness of quantity demanded of good A to changes in price of good B.

cross price elasticity of demand = percentage change in quantity demanded of good A / percentage change in price of good B

Price elasticity of demand measures the responsiveness of quantity demanded to changes in price of the good.

Income elasticity of demand measures the responsiveness of quantity demanded to changes in income.

Answer:

Carmen

Step-by-step explanation:

Given

See attachment for plot

Required

Player with the most runs

The number of runs is represented by the y coordinates.

So, the player with the most runs has the highest y coordinate.

From the attached plot, the y coordinate of each player is:

[tex]Paulo = 5[/tex]

[tex]Rebecca = 4[/tex]

[tex]Nardine = 9[/tex]

[tex]Jason = 10[/tex]

[tex]Carmen = 11[/tex]

By comparison, Carmen has the most runs (11)

Answer:

y = -|x-3|+2

Step-by-step explanation:

The y-intercept is 2, because absolute value takes values from 0 to infinity, and minus absolute value (as we have here) takes values from 0 to -infinity, so wee need to shift 2 upwards.

We can notice that the 0-point of the absolute value (without intercept) is at x=3, so we need |x - ?| to equal 0 when x = 3, so ? is 3.

y = -|x-3|+2

Answer:

The next two terms are: 1.05 and 1.20

Step-by-step explanation:

Given

[tex]Sequence: 0.6, 75\%, 9/10[/tex]

Required

Write out the next two terms

Since it is a linear sequence; first, we calculate the common difference (d)

[tex]d = 75\% - 0.6[/tex] or [tex]d = 9/10 - 75\%[/tex]

Express as decimals

[tex]d = 0.75 - 0.6[/tex] or [tex]d = 0.9 - 0.75[/tex]

[tex]d = 0.15[/tex] (in both cases)

So, we add 0.15 to 9/10, to get the next term

[tex]Next = 9/10 + 0.15[/tex]

[tex]Next = 0.9 + 0.15[/tex]

[tex]Next = 1.05[/tex]

Add 0.15 to 1.05, to get the next term

[tex]Next = 1.05 + 0.15[/tex]

[tex]Next = 1.20[/tex]

The next two terms are: 1.05 and 1.20

Answer: {y = x + 3, y = -3 x - 1}

{x + 3 = y, 3 x + y + 1 = 0}

Step-by-step explanation:

Answer:

The missing angle is 24 degrees

Step-by-step explanation:

The two angles form a straight line so they add to 180 degrees

x+156 = 180

Subtract 156 from each side

x+156-156 = 180- 156

x = 24

The missing angle is 24 degrees

[tex]105.56\ ft^3[/tex] of gravel was used.

Step-by-step explanation:

Given that,

The height of a cone, h = 6 feet

The diameter of the base of cone, d = 8.2 feet

Radius, r = 4.1 feet

We need to find the amount of gravel was delivered. The volume of a cone is given by :

[tex]V=\dfrac{1}{3}\pi r^2 h\\\\=\dfrac{1}{3}\times 3.14\times 4.1^2\times 6\\\\V=105.56\ ft^3[/tex]

So, [tex]105.56\ ft^3[/tex] of gravel was used.

Given:

The graph of a function and a blue line.

To find:

The correct name for the blue line.

Solution:

Domain: It is the set of inputs. These are the x-values for which the function is defined.

Range: It is the set of outputs. These are the y-values for the function.

Asymptote: The function approaches to a line as x approaches to -∞ or ∞ but not intersect the line, then the line is known as asymptote.

y-intercept: It is the intersection point of the function and the y-axis.

From the given graph it is clear that the function approaches to the blue line as x approaches to -∞ but not intersect the blue line.

So, the blue line is an asymptote of the function.

Look at the graph shown below the blue line represents an asymptote of the graph.

Answer:

QX = 5.7

Step-by-step explanation:

Here, we want to get QX

For a rectangle, the length of the parallel sides are equal

Thus,

SR will be 8 too

Since x is the midpoint of SR, we have it that RX is 4 too

The angle at each corner of the rectangle is 90 degrees each

Thus,

QRX is a right triangle

Mathematically, QX is the hypotenuse of this triangle as it is the side that faces the right angle

According to Pythagoras’ ; the square of the hypotenuse of a right triangle equals the sum of the squares of the two other sides

thus;

Qx^2 = 4^2 + 4^2

QX^2 = 32

QX = √(32)

QX = 5.7 units

Answer:

y=3x-6.5

Step-by-step explanation:

y-y1=m(x-x1)

y-(-0.5)=3(x-2)

y+0.5=3x-6

y=3x-6-0.5

y=3x-6.5

The slope of a line indicates the measure of the steepness and the direction of the line. The slope of any line can be calculated using any two distinct points lying on the line. The equation is y = 3x-6.5. The correct option is D.

The equation of a line is an algebraic form which represents the set of points, which together form a line in a coordinate system. The equation of line is a linear equation with a degree of one. It can be formed with the help of the slope and a point on the line.

The equation of a line passing through the point and slope is given as:

(y - y₁) = m (x - x₁)

(y - -( 0.5)) = 3 ( x - 2)

(y + 0.5) = 3 (x - 2)

(y + 1/2) = 3 (x - 2)

or

y + 0.5 = 3x - 6

y = 3x - 6.5

Thus the correct option is D.
