Answer:

To find the perimeter of a object you add up all the sides so

14.75+4.5+8.5+10.4+10.4+12.8=61.35(I converted to demsils since it just easier for me you don't have to do that.)

61.35=61 7/20

Hope This Helps!!!

Help with 7-12 please!​
OLEGan [10]

How to solve 7-10: if a coordinate (x, y) is on the line, then f(x) = y.

7. Since x is 6, look at the graph, which shows that y (or f(x)) is 4. (look at picture)

8. Same thing as 7. you will see that f(x) is 15.

9. The other way around. since we know y = 2, looking at the graph shows us that x = 3.

10. Repeat process of 9. x = 10.

How to solve 11 + 12: slope formula (rise-over-run)

11. (14-4)/(12-6) = 10/6 = 5/3.

12. (16-14)/(18-12) = 2/6 = 1/3.

(If possible brainliest is appreciated :D)

In the xy coordinate plane, the slope of a line is 4 and it passes through the point (1, 3). Find the equation of a line that is
igor_vitrenko [27]

Answer: Y=-1 or Y=-1+4

Step-by-step explanation:

<h3>Use the formula y2- y1 over x2-x1 so it should look like this 1-3 over 3-1 which is -2 over 2 then you divide that which is -1 and if you have to find one all you have to do is use one point label which is x and y so I pick (1,3) so you put 3=-1(1) once you have that you multipy so -1 times 1 is -1 so your gonna add 1 to the -1 and the three the -1 cancel out because it is a zero pair 3+1 is 4 so B=4 </h3>

Y = 2x + 3
BARSIC [14]

Answer:

Infinite solution

Step-by-step explanation:

There is 3 possible solutions to a system of linear equations:

  • One solution - two distinct lines that do not share y-intercept or slop intersect at a point
  • No solution - two distinct lines that share the same slope but not the same y-intercept never intersect and are parallel
  • Infinite solution - one distinct function represented two ways which in simplest form share the same slope and y-intercept

The first equation is in simplest form y=2x+3.

The second equation 2y=4x+6 when simplified becomes y=2x+3.

These are the same lines with the same slope and y-intercept. Therefore, they have infinite solutions.

How does substitution help you to solve systems of equations?
kipiarov [429]
In solving equations, each must have vales of x and y. X is any number and Y is the output of any number. If you substitute x for a number, you can solve the equation for y.
