What is the solution to the system please help
IrinaVladis [17]

Answer:

(-\frac{50}{13},-\frac{12}{13})

Step-by-step explanation:

To start, you need to find the equation of both of these lines. For the orange one, the slope can be found with the points (-5,0) and (0,-4), where there is a drop of 4 for a run of 5. This is a slope of -4/5, and a y-intercept of -4. For the purple line, you can use the points (-2,0) and (0,1), where there is a rise of 1 for a run of 2 or a slope of 1/2 and a y intercept of 1. Therefore, the two equations are:

y=-\frac{4}{5}x-4

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

You can now set them equal to each other:

-\frac{4}{5}x-4=\frac{1}{2}x+1

Add 4 to both sides:

-\frac{4}{5}x=\frac{1}{2}x+5

Multiply both sides by 2:

-\frac{8}{5}x=x+10

Multiply both sides by 5:

-8x=5x+50

Subtract 5x from both sides:

-13x=50

Divide both sides by -13:

x=-\frac{50}{13}

y=-\frac{12}{13}

Hope this helps!

the number of even integers between 1 and 103 is the same is the same as the number of odd integers between 4 and x. what is the
Ksju [112]
# of numbers between 1 & 103: 102
Half of that would be even numbers. So, 51 even numbers. 
Between 4 and x, there are 102 numbers. 4+102=106. 4+106=x. 106=x

Cam was bom weighing 8.6 pounds. Every day, he gained the same amount of weight. After 30 days, he weighed 14.9
guajiro [1.7K]

Answer:

So I'm not entirely sure about this one, but I believe he gained 0.21 pounds each day for 30 days

Step-by-step explanation:

Since Cam was born weighing 8.6 pounds and after 30 days weighed 14.9, subtract 14.9-8.6 to find how much he gained.

14.9 - 8.6 = 6.3

Now that we know how much he gained, we have to find out how much he gained per day for 30 days. To do this, divide 6.3 by 30

6.3 / 30 = 0.21

To make sure this answer is correct, multiply 0.21 by 30 and add that to 8.6. It should equal 14.9.

I hope this helps!

wendy is logging the number of video game levels she wins per hour. she has determined the function to be f(x) = 6x + 9, where x
True [87]
Since we are talking about real quantities (hours), x should be positive. Also, you need to take into account that Wendy needs to play in order to win game levels.
Therefore the domain will be: x > 0
