An ordered pair (x,y) is a solution to a system of equations if it makes all the equations true.
Let's check whether (–1, 5) makes the equations true.
Plugging –1 in the first equation for x and 5 in for y, we get
–1 + 5 = 4: TRUE
Plugging –1 in the second equation for x and 5 in for y, we get
–1 – 5 = –6: TRUE
Since it makes both the equations true, it's a solution to the system of equations. So the answer choice is D, the 4th one.
Answer:
Step-by-step explanation:
The x-intercepts exist where y is equal to 0...which is ON the x-axis. Hence, the name "x-intercept". These are caled zeros, solutions, and roots. This parabola goes through the x-axis at x = 0 and x = 4. It is at both of these locations where the y-coordinate is 0.
Answer:
Step-by-step explanation:
3g + 2h = 3*7 + 2*5
= 21 + 10
= 31
Hey!
Ignore the birthday party stuff and go to 95 first. Subtract 9 from 95 you get the answer 86. Next you need to find how many times 8 goes into 86. 86/8 which is 10 with a remainder of 6. Therefore, Guy can donate to 6 animal shelter. I hope this helps with future problems.
