Solve for x and y please

Answer:

-6

Step-by-step explanation:

The value of the given expression will be equal to -3.

Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication and division.

The solution to the expression is:-

=  4(  x  +  3  ) (  x + 1  )  /  (  x  +  5  )  (  x  -  5  )

=  4(  3 +  3  ) (  3  + 1  )  /  (  3  +  5  )  (  3  -  5  )

=  (  4  x  6  x  4 )  /  (  8  x   -2  )

=  -3

Therefore the value of the given expression will be equal to -3.

Monocots differ from the dicots In the structural features of the leaves, the stems, roots, and flowers. The differences start from the very beginning of the plant's life cycle: the seed. Monocots have one cotyledon, while dicots have two. When it comes to leaves,  monocots have narrow leaves with the typical parallel leaf veins. Dicots have broad leaves with a network of netted leaf veins.

b. The scenario is a function because each student just have to pay once.

Answer:

Step-by-step explanation:

y = mx  + c

Slope = m

y-intercept = c

1) y = -3x + 6

Slope = -3

y-intercept = 6

2) y = 4/3 x - 1

Slope = 4/3

y-intercept =  -1

3) y = -1/5x+3

Slope = -1/5

y-intercept = 3

Answer:

Step-by-step explanation:

y= -3x +6                         [tex]y=\frac{4}{3} x-1[/tex]

Answer:

I dont understand what your saying???

Step-by-step explanation:

The slope of the line in the graph is,

⇒ m = 1

The equation of line in point-slope form passing through the points (x₁ , y₁) and (x₂, y₂) with slope m is,

⇒ y - y₁ = m (x - x₁)

Where, m = (y₂ - y₁) / (x₂ - x₁)

Given that;

Two points on the line are (- 1, 0) and (0, 1).

Now,

Since, The equation of line passes through the points  (- 1, 0) and (0, 1).

So, We need to find the slope of the line.

Hence, Slope of the line is,

m = (y₂ - y₁) / (x₂ - x₁)

m = (1 - 0) / (0 - (-1))

m = 1 / 1

m = 1

Thus, The slope of the line in the graph is,

⇒ m = 1

Answer:

Parallel lines are lines that do not meet while perpendicular lines are aligned 90 degrees to each other.

Step-by-step explanation:

Imagine two straight lines, drawn side by side to each other with no angle between them. When they are drawn to infinite, no point of one line would touch the other.

Perpendicular lines are two or more line that meets at a point to form a right angle, that is, separated with an angle of 90 degrees to each other.

The correct statement about function is,

⇒ f (2k) = 0

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.\

Given that;

(x – 2k) is a factor of function f(x),

Since, (x – 2k) is a factor of function f(x),

Hence, x = 2k is a factor of function f(x),

Thus, We get;

⇒ f (2k) = 0

Thus, The correct statement about function is,

Answer:

y=-2/5x +3

Step-by-step explanation:

You get the y to be alone on it's side of the equal sign.

So you subtract 2/5 x from that side and what you do to one side you have to do to the other.

You get: y=-2/5x +3

Two expressions with equal sign is Equation. y= 3-2/5x is the solution for y if equation is 2/5x + y = 3.

Two expressions with equal sign is called as Equations.

Given Equation is 2/5x + y = 3, we need to solve for y.

You get the y to be alone on it's side of the equal sign.

So you subtract 2/5 x from that side and what you do to one side you have to do to the other.

2/5x + y = 3

y = 3-2/5x

Therefore  y=3-2/5x is the solution for 2/5x + y = 3 equation.

Step-by-step explanation:

The regression analysis output is as follows:

Intercept        7.856710924          1.316226455         5.969118       0.001889

Views

R-sq. = 69.73%

R-sq. (adj) = 63.68%

A

There are two variables used in this study, the independent and the dependent variable.

The independent variable is the number of online music video views and the dependent variable is the number of guitar sales.

B

The coefficient of determination R² specifies the percentage of the variation in the dependent variable (Y) that is forecasted or explained by linear regression and the forecaster variable (X, also recognized as the independent-variable).

Thus, the proportion of the variation of guitar sales that is explained by its linear relationship to music video views is 69.73%.

C

The least square regression line is:

[tex]y=7.856710924+0.094781123\cdot x[/tex]

The least square regression line implies that there is a positive relationship between the guitar sales and music video views. That is as the number of music video views increases the guitar sales increases. And vice-versa.

Thus, increased guitar sales were caused by online music video views.

Answer:

(-2/17, 5/17)

Step-by-step explanation:

Given the coordinates A (-3,-5) to B (9,4), we are to find the coordinate of the point cutting the line using the ratio 7:10

Using the midpoint formula;

M(X,Y) = {(ax1+bx2/a+b, (ay1+by2/a+b))

Given

x1 = -3, y1 = -5, x2 = 9, y2 = 4, a = 7 and b = 10

get the required coordinates;

X = ax1+bx2/a+b

X = 7(-3)+10(9)/7+10

X = -21+19/17

X = -2/17

Get the Y coordinate;

Y = ay1+by2/a+b

Y = 7(-5)+10(4)/7+10

Y = -35+40/17

Y = 5/17

Hence the required coordinate is (-2/17, 5/17)

Answer:

B

In the equation y=mx+b m is the slope of the line.

Therefore the coefficient in each of these equations is the slope.

A line with a perpendicular slope must have the inverse opposite of the actual line. For example if a line has a slope of 5, a perpendicular line to that line must have a slope of -1/5. If a line has a slope of 10, the perpendicular line has a slope of -1/10. If a line has a slope of 2 then the inverse opposite is -1/2 and that is the slope of the perpendicular line.

B is the only answer with the correct slope so B is the answer.

Answer:

y = - 5

Step-by-step explanation:

y = 4 is a horizontal line parallel to the x- axis

A parallel line must therefore be a horizontal line with equation

y = c

where c is the value of the y- coordinates the line passes through.

The line passes through (1, - 5) with y- coordinate - 5, thus

y = - 5 ← equation of parallel line

Answer:

13 units

Step-by-step explanation:

Because the c term (9 for f(x)) represents the y intercept. The y only moves the graph up or down. Since we are trying to get from 9 to -4 move down by 13 units.
