Answer:
14 or -22
Step-by-step explanation:
st=18
s=-4
-4+18=14
so t can be at 14
or -4-18=-22
t can be at -22
Well first think how many pounds are 1 ton?
but here it is
1 ton = 2,000 pounds
so they literally need 6,000 pounds of flour:/
now we gotta divide 6,000 by 5
6,000/5 = 1,200
we now have to divide that number by 12 :)
1,200/12 = 100
they would need 100 boxes!!
hope this helps chu
Answer:
Part a: janice
part b: difference of 3 dollars in hourly pay
Step-by-step explanation:
Divide the amount each person was paid by the hours they worked to find their hourly pay
48 divided by 4 = 12
84 divided by 7 = 12
108 divided by 9 = 12
janice Makes 15 dollars an hour
Answer:
→ The table is:
→ x → -1 → 0 → 1
→ y → -3 → 0 → 3
The graph of the line is figure d
Step-by-step explanation:
∵ y = 3x
∵ x = -1, 0, 1
→ Substitute the values of x in the equation to find the values of y
∴ y = 3(-1) = -3
∴ y = 3(0) = 0
∴ y = 3(1) = 3
→ The table is:
→ x → -1 → 0 → 1
→ y → -3 → 0 → 3
∵ The form of the linear equation is y = m x + b, where
∵ y = 3x
→ Compare the equation with the form
∴ m = 3
∴ b = 0
→ That means the slope is positive, then the direction of the line must
be from left tp right and passes through the origin
∴ The graph of the line is figure d
1.
the line of symmetry is x=2, means that the x coordinate of the vertex is x=2.
the point x=2 is the midpoint of the roots
and
.
so
Remark: in the x-axis, if c is the midpoint of a and b, then
2.
since
and
are roots
and
3.
equalizing:
in the left side factorize a, in the left side factorize 8:
in the right side use the difference of squares formula:
simplify by
substitute
with 4:
a=2
Answer: C)2
