Answer:
max profit is 8000
and units sold to obtain max profit is 3000
Step-by-step explanation:
This equation is in general form for a parabola equation
so the vertex represent the maximum profit and units to be sold
General form looks like this
7=a(x-p)²+q
where p and q is the vertex, ie the max point
in this equation
p=3000
q=8000
so max profit is 8000
and units sold to obtain max profit is 3000
2. Factor the expression. (1 point)
x² – 3x+2
(x+2)(x-1)
(x+2)(x+1)
(x-2)(x - 1)
(x-1) (x-3)
Factor x2−3x+2 using the AC method.

. He rowed 3 1/2 miles in 1/2 hour.What is the average speed in miles per hour.
Answer:
7 miles per hour
Step-by-step explanation:
3 1/2 miles = 7/2 miles
1/2 hours= 30 minutes
So,
In 30 mins, travelled 7/2 miles
In 1 min, travelled 7/2 ÷ 30= 7/2× 1/30 = (7×1)/(2×30) = 7/60 miles
In 60 mins, travelled (7×60)/60 miles = 420/60 miles = 7 miles.
Hence, the speed is 7 miles per hour.
Hope this helps :)

Can someone please help me with this?
4a - 5b = 7
substract 4a from both sides
4a - 5b - 4a = 7 - 4a
positive 4a with negative 4a
5b = 7 - 4a
devide both sides by 5
[tex] \frac{5b}{5} = \frac{7 - 4a}{5} [/tex]
[tex]b = \frac{7 - 4a}{5} [/tex]

. A National Institute of Health survey of 40467 U.S adults found that 3156 of them experienced at least one major depressive episode in the previous year. Make a 95% confidence interval for the proportion of all U.S. adults who experienced depression in that year. (Source: https://www.nimh.nih.gov/health/statistics/major-depression)
Using the confidence interval for sample proportion formula, the C.I is (0.075; 0.081)
Using the relation :
[tex]p ± z_{crit} \sqrt{ \frac{p(1 - p)}{n} } [/tex]
Sample size, n = 40467Sample proportion, p = 3156/40467 = 0.078Zcrit at 95% = 1.96Margin of Error = [tex] 1.96 \sqrt{ \frac{0.078(0.922)}{40467} } [/tex] Margin of Error = 0.0026128Lower boundary = 0.078 - 0.0026128 = 0.075
Upper boundary = 0.078 + 0.0026128 = 0.081
Hence, the confidence interval is (0.075; 0.081)

at a basketball game a vendor sold a combined total of 116 sodas and hotdogs. The number of hotdogs sold were 36 less than the number of sodas sold find the number of sodas sold and the number of hotdogs sold.
Answer: 76 Sodas and 40 hot dogs
Step-by-step explanation:
Let S and H represent the numbers of Sodas and Hot dogs.
We are told that:
S + H = 116
We also see that:
H = S - 36
==
Take the second equation's value for H (S - 36) and use it in the first:
S + H = 116
S + (S-36) = 116
2S = 152
S = 76
and therefore H = S - 36, or 40.
76 + 40 = 116 [Checks]
76 Sodas and 40 hot dogs

(n - 1)² =n² - 2n + 1<C and <F are a linear pair. If m<C = 3x and m<F = 3x + 18, find m<F.
Answer:
108
Step-by-step explanation:
A linear pair adds to 180 degrees
<C + <F = 180
3x+ 3x+18 = 180
6x+18 =180
6x+18-18= 180-18
6x =162
6x/6 =162/6
x=27
<F = 3x+18 = 3(27)+18 =81+27 = 108

Y=2x-1 và y=3x+2 khi
Answer:
x = 3, y= 5
Step-by-step explanation:
y = 2x - 1 -----(1)
y = 3x + 2 ----(2)
From (1)
2x - y = 1 ----(3)
From (2)
3x - y = -2 -----(4)
Solving (3) and (4) simultaneously
2x - y = 1
- 3x - y = -2
___________
x = 3
subst. x = 3 in (1)
2(3) - y = 1
6 - y = 1
y = 6-1
y = 5
Hence, x = 3, y = 5
Find the first 5 terms of the sequence a1= -4, an = 3an-1 -2 for n > 1.
==========================================================
Explanation:
The notation [tex]a_1 = -4[/tex] tells us that the first term is -4.
To generate the next term, we'll use the recursive rule [tex]a_n = 3*a_{n-1}-2[/tex] which is probably better written as [tex]a_n = 3*(a_{n-1})-2[/tex]. That rule says: "Whatever the previous term is, multiply by 3 and subtract off 2 to get the next term".
This means,
2nd term = 3*(1st term) - 2 = 3*(-4)-2 = -143rd term = 3*(2nd term) - 2 = 3*(-14)-2 = -444th term = 3*(3rd term) - 2 = 3*(-44)-2 = -1345th term = 3*(4th term) - 2 = 3*(-134)-2 = -404Therefore, the first five terms are: -4, -14, -44, -134, -404

Answer:
y+3=1/5(x+4)
Step-by-step explanation:
Hi, I would recommend that you memorize the point slope formula, as it comes up often in later grades.
Point slope formula is y - y1 = m * (x - x1)
and so since we're given the slope (m), we simply plug it in.
y - y1 = 1/5 * (x - x1)
then we would plug in our x and y
(-4,-3)--> -4 is the x and -3 is the y
y+3=1/5(x+4) double negatives= a positive.
