Which inequality represents all values of x for which the product below is
defined?
20 pts
Step-by-step explanation:
√a is defined only when a >= 0.
Therefore for √4x * √(x + 2) to be defined, both 4x and x + 2 must be non-negative.
When 4x >= 0, x >= 0.
When x + 2 >= 0, x >= -2.
x >= 0 and x >= -2, therefore we have x >= 0. (D)
Ron asked 18 classmates whether they prefer granola bars over muffins.
He used a calculator to compare the number of classmates who said yes to the total number he surveyed.
The calculator showed the result below.
The ratio of the measures of the angles in angles JKH is 2:3:4.
Answer:
J=40º, K=60º, H=80º
Step-by-step explanation:
since all angles of a triangle add up to 180º, we can make an eqaution.
3x+2x+4x=180
9x=180
x=20
J=2x=20x2=40º
K=3x=20x3=60º
H=4x=20x4=80º
y + 2 = 2/3 (x - 4)
Slope
Answer: Y = 2/3x - 14/3
Answer:
2/3
Step-by-step explanation:
y+2=2/3 (x-4)
1. multiply parentheses (y+2=2/3x-8/3
2. subtract 2 from both sides (y=2/3x-2/3
3. 2/3x is the slope

PLZ HELP ASAP DUE TODAY!
Answer:
5(9x + 2y + 10)
or
x = 0
y = -5
Step-by-step explanation:
If you are just factoring this, you will factor a 5 out from everything.
5(9x + 2y + 10)
or if you are trying to solve just isolate one of the variables and then substitute it into the original equation
45x + 10y = 50
10y = 50 - 45x
y = 5 - 4.5x
45x + 10(5-4.5x) + 50
45x + 50 - 45x + 50
x=0
45(0) + 10y + 50
0 + 10y + 50
10y + 50
10y = -50
y = -5
and it would be x = 0 and y = -5

A parabola can be drawn given a focus of (4, -3) and a directrix of y=5 Write the equation of the parabola in any form.
Answer:
The equation of the parabola is (x - 4)² = -16(y - 1)
Step-by-step explanation:
The standard form of the equation of the parabola is (x - h)² = 4p(y - k), where
The vertex of the parabola is (h, k)The focus is (h, k + p)The directrix is at y = k - p∵ The focus of the parabola is (4, -3)
∵ The focus is (h, k + p)
∴ h = 4
∴ k + p = -3 ⇒ (1)
∵ It has a directrix of y = 5
∵ The directrix of the parabola is y = k - p
∴ k - p = 5 ⇒ (2)
→ Add equations (1) and (2) to find k and p
∵ (k + k) + (p - p) = (-3 + 5)
∴ 2k + 0 = 2
∴ 2k = 2
→ Divide both sides by 2
∴ k = 1
→ Substitute the value of k in equation (1)
∵ 1 + p = -3
→ Subtract 1 from both sides
∴ 1 - 1 + p = -3 - 1
∴ p = -4
∵ The form of the equation of the parabola is (x - h)² = 4p(y - k)
→ Substitute the values of h, k, p in it
∴ (x - 4)² = 4(-4)(y - 1)
∴ (x - 4)² = -16(y - 1)
∴ The equation of the parabola is (x - 4)² = -16(y - 1)

A factory produces 60 candy bars in 5 minutes. If the factory continues producing at the same rate. How many candy bars does it produce in 10 minutes, 1 minute, 7 minutes
Answer:
10 minutes would be 120 candy bars.
1 minute would be 12 candy bars.
7 minutes would be 84 candy bars.
Step-by-step explanation:
For 10 minutes you multiply 60 times 2, which would be 120 candy bars.
For 1 minute you divide 60 by 5, which would be 12 candy bars.
For 7 minutes you would add 60 and 24, which would be 84 candy bars.

Jada says she can find 87-59 by taking away 60 and adding 1 so it is the same as 27+1 or 28. Explain why jadas method to calculate 87-59 makes sense.
Answer:
The correct answer is 28.
Step-by-step explanation:
Actually Jada makes problem simpler by adding and subtracting 1
that is
87 ₋ 59 ₋1 ₊ 1
so there would be no effect on our final answer because we have added 1 and also subtracted 1
Now,
87 - 59 -1 + 1
87 - 60 +1 ( ∵ -59 - 1 = -60 )
27 + 1 (∵ 87 - 60 = 27 )
28
so the final answer is 28 .

Mai's family drink a total of 10 gallons of milk every 6 weeks. How many weeks does it take the family to consume 3 gallons of milk?
Answer:
1.8 weeks
Step-by-step explanation:
The number of weeks it takes for consuming the 3 gallons of milk is as follows:
It is given that the total of 10 gallons of milk drink for every 6 week i.e. 5 by 3
Now in order to determine the weeks we have to reciprocal the ratio i.e. 3 by 5
Now for 3 gallons it would be
[tex]= \frac{3}{5}\times 3[/tex]
= 1.8 weeks
