Step-by-step explanation:
Do 25 + 25 + n + n.
n=18
The bottom question is also
n=18
Answer:
x-intercept is (40/7, 0) and y-intercept is (0, 5)
Step-by-step explanation:
x-intercept ==> y-coordinate is 0 ==> y=0
y-intercept ==> x-coordinate is 0 ==> x=0
because the function is 7x + 8y = 40
when y = 0 ==> 7x = 40 ==> x = 40/7
so the x-intercept is (40/7, 0)
when x = 0 ==> 8y = 40 ==> y = 5
so the y-intercept is (0,5)
2x+4=10-4x
-2x+4=10
-2x=6
X=-3
