Answer:

(75 * 3) + 55 + 104 + 85 + 3.

Answer:

<em>Mario has -16 points.</em>

Step-by-step explanation:

Race car driver Mario won 3 races and earned 75 points for each win.

Total points won = 75\times3=225

During the fourth race he had deductions of 55 points 104 points and 85 points but earned 3 points for finishing.

Total points Mario has now = 225+(-55)+(-104)+(-85)+3

= -16 points

<em>Therefore, Mario has -16 points.</em>

On a coordinate plane, a dashed straight line with negative slope goes through (0, 1) and (2, negative 2). Everything to the lef
charle [14.2K]

Answer:

y

Step-by-step explanation:

The straight line passes through (0,1) and (2,-2).

Equation of a straight line passing through two points (x1,y1) and (x2,y2)

is given by:

y-y_{1}=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}(x-x_{1})

y-1=\frac{-2-1}{2-0}(x-0)

y=-\frac{3}{2}x+1

Everything to the left of the line is shaded.

We have to visualize the graph:the straight line has a positive y-intercept and a negative slope.The graph is given in the attachment below.

From the figure we can see origin lies on the shaded region.Hence (0,0) should satisfy the inequality.

LHS=y=0

RHS=-\frac{3x}{2}+1=1\ (x=0)

LHS<RHS as 0<1

Hence , the inequality is:

y

Please help me and show your work
morpeh [17]

Answer:

Step-by-step explanation:

y = 3x + 4

Plugin x = 3 in the equation,

y = 3*3 + 4

 = 9 + 4

y = 13

Plugin x = 4 in equation,

y = 3*4 + 4

  = 12 + 4

y = 16

Plugin x = 5 in the equation,

y = 3*5 + 4

  = 15 + 4

y = 19

2) y =x - 7

Plugin x = 10 in the equation

y = 10 - 7

y = 3

Plugin x = 15 in the equation

y = 15 - 7

y = 8

Plugin x = 20 in the equation

y = 20 - 7

y = 13

The graph of a proportional relationship passes through the point (6, 21). What is the equation for the relationship?​
Kipish [7]

Answer:

The equation for the relationship is y = \frac{7}{2}\cdot x.

Step-by-step explanation:

Given that point (x,y) = (6, 21) is part of a direct relationship. That is:

y \propto x

y = k\cdot x (1)

Where k is the proportionality constant.

If we know that x = 6 and y = 21, then the proportionality constant is:

k = \frac{y}{x}

k = \frac{21}{6}

k = \frac{7}{2}

Lastly, the equation for the relationship is y = \frac{7}{2}\cdot x.
