Step-by-step explanation:
Answer:
31x² - 2
Step-by-step explanation:
5(2x²-1)+3(7x²+1) = 5*2x² - 5*1 + 3*7x² + 3 = 10x² - 5 + 21x² + 3 = 31x² - 2
Y = mx + b
where m is the slope and b is the y-intercept.
1. 2x + 3y = 12
3y = -2x + 12
y = -2x + 4
y-intercept is 4
2. x - 4y = 20
-4y = -x + 20
y = -x - 5
y-intercept is 5
3. y = 2x - 9
this one is easy because it's already in standard form
y-intercept is -9
Answer: 2 x2=4 or 2x-2=-4
Step-by-step explanation: its simple math
Answer:
x = 9.8
Step-by-step explanation:
They are same shape so we just get the ratio.
AB/JK = BC/KL
5 / 7 = 7 / x
5x = 49
x = 9.8
