Answer:

D (-2,4)

Step-by-step explanation:

When there is a solution for the System of Linear Equations, this one must satisfy both equations. In this case, represented by the red line and the blue one. Since a line, is a set of points according to Euclidean Geometry.

Then the only point in common is the point of intersection, therefore the solution. So, it's D.

The answer in miles for how many miles the cab driver drove and how much money it costed for every mile

kotegsom [21]

For Bert's, it's $1.00 and $3.00 per mile.
We can set up this equation:
y = 3x + 1
Where x represents the number of miles.

For Madeline's, it's $3.00 at first and $2.00 per mile.
We can set up this equation:
y = 2x + 3

Hope this helps :)

The length of the top of a table is 7 m greater than the width. the area is 78 msquared2. find the dimensions of the table.

Zinaida [17]

Let the width = x
the length = x+7
=> Area equation = length x width = x(x+7) = x^2 +7x = 78
=> x^2+7x -78 = 0
=> (x-6)(x+13)=0
=> x=6 or x=-13(no)
=> the width = 6 m
=> the length = 6+7= 13 m

The graph shows the proportions of blue paint and yellow paint that Briana mixes to make green paint. What is the slope of the l

kotegsom [21]

Answer:

Slope = ⅚

Step-by-step explanation:

Using the coordinates of two points in the graph, say (0, 0) and (6, 5).

$\frac{y_2 - y_1}{x_2 - x_1} = \frac{5 - 0}{6 - 0} = \frac{5}{6}$

The slope of the graph is ⅚.

The slope represents the ratio of proportion of yellow paint to blue paint that must be mixed together to produce green paint.

This means, to make green paint, for every 5 parts of yellow paint, 6 parts of blue paint is required to be added as a mixture.

If f(x) = <img src="https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B9%7D" id="TexFormula1" title="\frac{1}{9}" alt="\frac{1}{9}" align=

boyakko [2]

Answer:

Solution given:

f(x) = $\frac{1}{9}$ x-2

let f(x)=y

y = $\frac{1}{9}$ x-2

interchanging role of x and y

x= $\frac{1}{9}$ y-2

x+2= $\frac{1}{9}$ y

y=9(x+2)

y=9x+18

F-¹(x)=9x+18

and

F-¹(-1)=9*-1+18=-9+18=9
