The quadratic function f(x) = x^2 has ________.
A.
exactly one zero
B.
no zeros
C.
exactly two zeros
D.
more than two zeros
Answer:
The answer should be A) exactly one zero
Step-by-step explanation:
The roots (zeros) are the x values where the graph intersects the x-axis. To fine the roots (zeros), replace y with zero and solve for x.
Solve for x: 23 = -4n + 15 – 8n + 2
please help
Step-by-step explanation:
Simplify the equation for n.
[tex]23 = - 4n + 15 - 8n + 2[/tex]
[tex]23 = - 12n + 17[/tex]
Subtract 17 from both sides:
[tex]6 = - 12n[/tex]
Divide each side by -12:
[tex] - \frac{1}{2} = n[/tex]
Appropriate Question :
Solve for n :
23 = -4n + 15 – 8n + 2Solution :
[tex]\qquad{ \dashrightarrow \: { {{ \sf{ 23 = -4n + 15 - 8n + 2 }}}}\:}[/tex]
[tex]\qquad {\dashrightarrow \: { {{ \sf{ 23 = -4n - 8n + 15 + 2 }}}}}\:[/tex]
[tex]\qquad {\dashrightarrow \: { {{ \sf{ 23 = -12n + 17 }}}}}\:[/tex]
[tex]\qquad {\dashrightarrow \: { {{ \sf{ 12 n= 17 - 23 }}}}}\:[/tex]
[tex]\qquad {\dashrightarrow \: { {{ \sf{ 12n = - 6 }}}}}\:[/tex]
[tex]\qquad {\dashrightarrow \: { {{ \sf{ n = - \dfrac{6}{12} }}}}}\:[/tex]
[tex]\qquad {\dashrightarrow \: { {{ \sf{ n = - \dfrac{1}{2} }}}}}\:[/tex]

7. Which situation could be represented by the graph below?
a. The speed increases and then decreases.
b. The speed increases and then remains constant.
c. The speed stays constant and then increases
d. The speed decreases and then remains constant.
poods
Time
HELP PLZ
Answer:
b. The speed increases and then remains constant. You can see that in the beginning there is a larger slope, which indicates a faster speed, followed by a plateau, which shows a consrant speed.
The variable m in slope intercept form represents the y- intercept ? True or false
No.
m represents the slope while b represents the y-intercept.
Answer: False
Step-by-step explanation:
Because the slope-intercept form is y=mx+b and m represents slope.
At the movies, you buy 3 bags of popcorn and 2 soft drinks and it costs you $16.50. Layne buys 2 bags of popcorn and 1 soft drink and his total is $10.25. Find the cost of one bag of popcorn and one soft drink.
Answer:
Popcorn= $4.5
Soft drink= $1.5
Step-by-step explanation:
Let p represent the cost of popcorn and let a represent the cost of soft drinks
3p + 2s= 16.50
2p + s= 10.5
Multiply equation 1 by 2 and equation 2 by 3
6p + 4s = 33
-
6p + 3s = 31.5
s= 1.5
Substitute 1.5 for s in equation 1
3p + 2s = 16.50
3p + 2(1.5)= 16.50
3p + 3 = 16.50
3p = 16.50-3
3p = 13.5
p = 13.5/3
p = 4.5
Hence the price of a bah of popcorn is $4.5 and soft drink is $1.5

The volume of a rectangular box can be found with the formula v = l * w * h. Solve for l, and find the length of the rectangular box when w = 6 inches, h = 7 inches, v = 210 cubic inches.
Answer: Length =5 inches
Step-by-step explanation:
Multiply 6(w)x7(h) which gives you 42 then divide 210(v) by 42 which gets you 5(l)

a solar lease customer built up an excess of 6,500 kilowatts hour (kwh) during the summer using his solar panels. when he turned his electric heat on, the excess be used up at 50 kilowatts hours per day
Question:
A solar lease customer built up an excess of 6,500 kilowatts hour (kwh) during the summer using his solar panels. when he turned his electric heat on, the excess be used up at 50 kilowatts hours per day .
(a) If E represents the excess left and d represent the number of days. Write an equation for E in terms of d
(b) How much of excess will be left after one month (1 month = 30 days)
Answer:
a. [tex]E = 6500 - 50d[/tex]
b. [tex]E = 5000[/tex]
Step-by-step explanation:
Given
Excess = 6500kwh
Rate = 50kwh/day
Solving (a): E in terms of d
The Excess left (E) in d days is calculated using:
[tex]E = Excess - Rate * days[/tex]
The expression uses minus because there's a reduction in the excess kwh on a daily basis.
Substitute values for Excess, Rate and days
[tex]E = 6500 - 50 * d[/tex]
[tex]E = 6500 - 50d[/tex]
Solving (b); The value of E when d = 30.
Substitute 30 for d in [tex]E = 6500 - 50d[/tex]
[tex]E = 6500 - 50 * 30[/tex]
[tex]E = 6500 - 1500[/tex]
[tex]E = 5000[/tex]
Hence, there are 5000kwh left after 30 days

Kristel had 290 stickers at first. After she gave some stickers to her sister and Tricia gave 42 to kristel. How many stickers did kristel give to her sister?
Answer:
332 - x
Step-by-step explanation:
We are told that:
Kristel had 290 stickers.
Let the number of stickers given to her sister be x;
Tricia gave Kristel 42 afterwards.
To find the number of stickers Kristel gave to her sister; we have:
= 290 + 42 - x
= 332 - x

In the table below, y varies inversely as x. What is the missing value?
Answer:
The value of y is 0.5, so the answer is C.Step-by-step explanation:
Find first the constant of variation.
Given: x = 3, y = 4
Find: k = ?
Formula:
[tex]y = \frac{k}{x} [/tex]
Solution:
[tex]y = \frac{k}{x} \\ 4 = \frac{k}{3} \\ 12 = k[/tex]
Then, find the value of y in the third box.
Given: x = 24, k = 12
Find: y = ?
Formula:
[tex]y = \frac{k}{x} [/tex]
Solution:
[tex]y = \frac{k}{x} \\ y = \frac{12}{24} \\ y = \frac{1}{2} \\\boxed{y = 0.5}[/tex]
