Chapter : Linear equations
Lesson : Math for Junior High School
7x + 14y = 28
if want to find x and y, we must substitution value 0 to the equation x and y :
# If x = 0, then :
7x + 14y = 28
= 7(0) + 14y = 28
= 0 + 14y = 28
= 14y = 28 → y = 28/14
= y = 2
# If y = 0, then :
7x + 14y = 28
= 7x + 14(0) = 28
= 7x + 0 = 28
= 7x = 28 → x = 28 / 7
= x = 4
and that result was proven x = 4 and y = 2
Two lines to be parallel their slopes have to be equal.
so m1 = m = 4
y = mx + b ( Slope intercept form)
y = 4x + b
(3,0) is on the line:
0 = 12 + b
b = -12
y = 4x - 12
C. if the able is 1/2 then it would mean the gas to be an even amount of each color. say the is 3 red ants 3 black and want to know the probability of drawing a black Male on the first draw . then you would count the marbles which is 3 over the total of 6 and when simplified it is 1/2
Answer:
<h2>TRUE</h2>
Step-by-step explanation:
Answer:
C: 40 degrees
Step-by-step explanation:
50+2y+y+10=180
60+3y=180
3y=120
y=40
