Answer:
2,4 is indeed correct on edg.
Graphs that show a linear function is second option
The linear equation graphs are the equation of straight line graph with slope.
for example y = mx where (x,y) be the point on the line and m be the slope.
here the only second graph shows a straight line graph. y values changes by when x value changes. there is a slope.
when we a x value we can compute the corresponding y value.

I sold something on ebay and I go to the UPS store to
ship the package. The cost for the box is $3, and it cost
$4.50 per pound to ship.
1) Write an equation to model this situation.
2) Is the domain discrete or continuous? Explain
First you will input the equation, then submit it, then you
will be asked to explain.
imple
Answer:
1) 3+4.50x = total cost
2) continuous, because x will be the continuous change depending on the pounds
Step-by-step explanation:
The equation to model the situation is C(w) = 3 + 4.50w, and the domain is continuous because weight (w) can take any real number value for the package.
1. The equation to model this situation can be written as follows:
Total Cost (C) = $3 (Cost of the box) + $4.50 per pound (Weight of the package in pounds)
Let's denote the weight of the package in pounds as "w." The equation is:
C(w) = 3 + 4.50w
2. The domain in this situation is continuous. The weight of the package (w) can take any real number value, and the cost function C(w) is valid for all real values of weight. There are no restrictions or gaps in the possible values of weight, meaning it is continuous.
In summary, the equation to model the situation is C(w) = 3 + 4.50w, and the domain is continuous because weight (w) can take any real number value for the package.

The sum of three consecutive numbers is
42. Find the largest number in the set
Answer:
20
Step-by-step explanation:
Well consecutive numbers mean that the 3 numbers will follow each other in smallest to largest.
Example : 6, 7, 8 or 6,34,87
Non-Example : 7, 9, 6
As long as the number is greater than the one before it they are consecutive.
Following this rule I have come up with the numbers :
10, 12, 20
These three numbers are consecutive and equal to 42.
Now to find the largest number in this set just look at the greatest value which would be 20.
I don't have an entire explanation for this as I just did it in my head but I do hope it is correct.

Hockey teams are often confronted with the dilemma of whether or not to pull a goalie at the end of the game when they are down a goal or two. One analyst reports that in 40% of those games in which a goalie was pulled a goal was scored with one empty net, and of those goals scored 25% were scored by the team that pulled the goaltender. Given that the goalie has been pulled by a team, what is the probability that team will score a goal?
Answer:
Step-by-step explanation:
so 30% of the total number of goals shot is 5
30% of what number is 5....turn ur percent to a decimal..." of " is multiply
let the number of shots represent x
0.30x = 5...divide borh sides by 0.30
x = 5/0.30
x = 16.66 shots

Answer:
7/10
Step-by-step explanation:
1/10 = 2/20
1/4 = 5/20
2/5 = 8/20
11/20 = 11/20
We can see that the next term is just 11/20 + 3/20, as 3/20 is added onto each of the next terms.
11/20 + 3/20 = 14/20, which can be simplified to 7/10.

of it. Who mowed most of the lawn? How much of the lawn still needs to be mowed?
Answer:
Ms Rios mowed more
Step-by-step explanation:
I'm assuming that there's 100% of the lawn so if Ms Rios mowed 27% of the lawn when it was at 100% it would be at 73%
Now if her son mowed 14% and it was still at 100% it would be at 86%
So in the end Ms Rios mowed more of her lawn

Solve the system of equations – 5x + y = 56 and x + y = -4 by combining the
equations.
Answer:
Your solution is (-10, 6).
Step-by-step explanation:
Combining the equations is also known as substitution. This is done when you substitute one variable into another equation.
-5x + y = 56
x + y = -4
Let's change the second equation into one with one variable on each side.
y = -x - 4
Now, plug this into your first equation.
-5x + (-x - 4) = 56
Distribute the + sign.
-5x - x - 4 = 56
Combine the like terms.
-6x - 4 = 56
-6x = 60
Isolate x by dividing both sides by -6.
x = -10
Now plug this back into either equation.
-10 + y = -4
Add 10 to both sides to find y.
y = 6
Your solution is (-10, 6).
Check this by plugging in these values into the equation you have not checked yet.
-5(-10) + (6) = 56
50 + 6 = 56
56 = 56
Your solution is correct.
Hope this helps!
Answer:
x=-10; y=6
Step-by-step explanation:
combine the equations:
-5x + y + x + y = 56 +(-4)
-4x + 2y = 52
add 4x to each side
2y=52+4x
divide by 2
y=26+2x
now substitute 26+2x for y in the second equation:
x + 26 + 2x = -4
3x + 26 = -4
3x = -30
x = -10
therefore y = 6
Question 1
Find the measure of each angle indicated.
Answer:
90
Step-by-step explanation:
Answer:
90
Step-by-step explanation:
x + 70 =120 {Exterior angle theorem}
x = 120 - 70
x = 50
y = x {Vertically opposite angles}
y = 50
z + 50 + 40 = 180 {Angle sum property}
z + 90 = 180
z = 180 - 90
z = 90

What is the slope of the line that passes through the points (5, -4)(5,−4) and (7, -4) ?(7,−4)? Write your answer in simplest form.
Answer:
the slope is 0, m=0
Step-by-step explanation:
do the equation y2 - y1 over x2 - x1
Equation of a line is the y = 3x - 1 is with a slope of 3 and a passing point of (2, 5).
What is meant by slope?An angled surface, especially a hill or mountain, or the angle at which something rises: On flat terrain, students develop their directional skiing skills.A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes.The ratio of the difference between the y- and x-coordinates of the two points that make up the line must be calculated. The slope of the line is the value that is obtained. It displays how the line's y-axis rise compares to its x-axis run.Here, slope of line equals 3.
Passing the buck (2, 5)
line equation
(y - y₁) = m (x - x₁)
y - 5 = 3 (x - 2) (x - 2)
y - 5 = 3x - 6
y = 3x - 6 + 5
y = 3x - 1
So, the equation of the line traversing the points (2, 5) and having a slope of 3 is y = 3x - 1.
The complete question is : A line with a slope of 3 passes through the point (2, 5). Write an equation for this line in point-slope form.
