Answer: 245 cu. cm.
Step-by-step explanation:
4/7-2/5=20/35-14/35=6/35
42 cm3 represents 6/35 of the total volume
how many 6/35's are in 35/35 ? (the total volume)
(35/35)/(6/35)=(35/35)*(35/6)=35/6=5 5/6
(5 5/6)*(42)=(35/6)*(42)=35*7=245 cm3 is the total volume
Answer:
0, 1
Step-by-step explanation:
The discriminant is b² - 4ac where we have ax² + bx + c, in this case a = -4, b = 12, c = -9 so D = 12² - 4(-4)(-9) = 0.
Because the discriminant is 0 that means that f(x) only has one solution for x meaning that it has only 1 x-intercept.
Answer:
93
Step-by-step explanation:
Line EJ is a straight line, with Line DC cutting through it. So 180 = Angle DCJ + Angle DCE. So Angle DCE = 48. Triangles are equal to 180°. So 180 = ? +39 +48. So ? = 93
The most convenient method I would choose is slope-intercept form, which is y=mx+b. So, make this equation equal in terms of y.
x-y=5
subtract x from both sides
-y = 5 - x
multiply both sides by -1 so y isn't negative
y = 5 + x
5 +x is the same thing as x+5, so
y = x+5
Now, you can easily sub in any number for x and you can easily get y. Here are some points you can plot:
(0, 5), (1, 6), (2, 7), (3, 8) and the list goes on. I hope this helped!
