Four less than the product of 6 and a number equals 3
Answer:
-1/6 (written as a fraction)
Step-by-step explanation:
our goal here is to get n by itself
6n-4=3
add 4 to both sides
6n=-1
divide both sides by 6
n= -1/6 (a fraction)
during a musical an orchestra is playing. as the music plays, the volume changes in the beginning of the piece can be modeled by the equation s=10|x-4|+50 where s represents the sound level in decibels and x represents the number of measures of music played. explain in words each step to find the following question:
at what number(s) measures played would the sound level be at 80 decibels?
Answer:
X = 1 ; x = 7
Step-by-step explanation:
Given the equation:
s=10|x-4|+50
s = sound level in decibels ; x = number of measures of music played
Take away 50 from Both right hand and left hand side of the equation
Recall s = 80
80 - 50 = 10│x - 4│+ 50 - 50
30 = 10│x - 4│
To get rid of the absolute value sign, append ± to left hand side
± 30 = 10x - 40
Minimum value of x : - 30 + 40 = 10x ; 10 = 10x ; x = 1
Maximum value of x : 30 + 40 = 10x ; 70 = 10x ; x = 7
Divide. Give the quotient and remainder.

Can anyone solve this for me :))?
Answer:
x = 32°
y = 17°
Step-by-step explanation:
Let's look at the bottom triangle since it has two angles.
62° + 75° = 137°
180° - 137° = 43°
The missing angle measure is 43°. Since the two angles make up a straight line,
(4x + 9)° + 43° = 180
4x + 52° = 180°
4x = 128°
x = 32°
The angle measuring 62° is a vertical angle so the angle opposite it is also 62°. The missing angle for that triangle would 40° because 180° - 140° = 40°.
62° + 40° = 102°
180° - 102° = 78°
(5y - 7)° = 78°
5y = 85°
y = 17°
Hope that helps.
What is the slope of the line that goes through (5,-11) and (-9, 17)?
Answer:
-2
Step-by-step explanation:
We can use the slope formula
m = ( y2-y1)/(x2-x1)
= ( 17 - -11)/( -9 -5)
= ( 17 +11)/( -9 -5)
28/-14
= -2
Answer: -2
Step-by-step explanation:
X=-9-5=-14
Y=17 - - 11=28

Answer:
d = 0
Step-by-step explanation:
cancel equal terms on both sides of the equation
= 8d = 6d
move variable to the left and change its sign
8d - 6d = 0
2d = 0
divide both sides of the equation by 2
d = 0
Answer:
d = 0
Step-by-step explanation:
-7 and -7 cancel out
8d = 6d
collect like terms 8d - 6d
8d-6d=0
2d = 0
divide both sides
d=0

4) The line shown represents the amount of money
left on a gift card, y, after Mina buys lattes. After
buying 2 lattes, she has $2 left. What is an
equation of the line in point-slope form?
Answer:
[tex] y - 2 = -3(x - 2) [/tex]
Step-by-step explanation:
The equation of the line in point-slope form is given by the formula, [tex] y - b = m(x - a) [/tex], where,
(a, b) = coordinates of a point on the line.
[tex] m = slope = \frac{y_2 - y_1}{x_2 - x_1} [/tex]
Given that after buying 2 lattes, she has $2 left, this represents a point on the line which is (a, b) = (2, 2). That is, when x = 2 lattes, y = $2.
Let's find the slope using the point (2, 2) and any other point on the line, say at x = 1, when y = 5, that's (1, 5).
[tex] m = slope = \frac{y_2 - y_1}{x_2 - x_1} = \frac{5 - 2}{1 - 2} [/tex]
[tex] = \frac{3}{-1} [/tex]
[tex] m = slope = -3 [/tex]
Plug m = -3, a = 2, and b = 2 into point-slope form.
[tex] y - b = m(x - a) [/tex]
[tex] y - 2 = -3(x - 2) [/tex]

Can someone please explain how they got 12??
Answer:
They got 12 by multiplying 3 × 4
Step-by-step explanation:
They used distributive property to multiply the 3 by each number in the parentheses
3 × x/3 = 1x = x
3 × 4 = 12
x + 12 = 6 × 3
They mutliplied 6 × 3 to get 18
x + 12 = 18
They then subtracted both sides by 12 to isolate the variable
x + 12 - 12 = 18 - 12
x = 6
Answer:
hope this helps! lmk if you still dont understand it!
:)
Step-by-step explanation:
you do 3*4 which gives you 12 and 3*x/3, but you should keep it as x
6*3 is 18
x+12=18 (solve for x)
-12=-12
x=6
check the answer:
3*(6/3+4)=6*3
3(2+4)=6*3
6+12=6*3
18=18

A triangle has sides with lengths of 38 feet, 56 feet, and 69 feet. Is it a right triangle?
Answer:
No
Step-by-step explanation:
Assume that it is a right triangle for now
According to the Pythagorean Theorem...
(38)^2 + (56)^2 = (69)^2
4580 ≠ 4761
Both sides are not equal, and hence the Pythagorean Theorem can't be applied to the triangle. It is not a right triangle.
An online streaming service deducts $7 from Serena’s account every month of a year. After 1 year, how much do the streaming service fees change Serena’s account?
Answer:
$84
Step-by-step explanation:
This is a super simple question. All you have to know is how much money will be charged a month, and how many months there are in a year. Just simply multiply 7 by 12 as the streaming service is charging 7 dollars a month and there are 12 months in a year. After you multiply the two numbers, you should end up with 84 dollars charged after 1 year.
2) Suppose 120 people are surveyed and asked about their eating habits. 50 people
stated that they like Raising Cane's chicken fingers, 80 people said that they like
Layne's chicken fingers. If 10 people don't like either, then...
a) What is the probability that someone surveyed likes both Raising Cane's and
Layne's chicken fingers?
Answer:
1/6
Step-by-step explanation:
Given that :
Total surveyed (u) = 120
n(Cane's chicken fingers) = 50
n(Layne's chicken fingers) = 80
n(do not like either) = 10
a)
What is the probability that someone surveyed likes both Raising Cane's and Layne's chicken fingers?
n(Cane's n Layne's) = 20
u = 120
P = required outcome / total possible outcomes
P(Layne's and Cane's chicken) = [n(Cane's n Layne's)/ u]
= 20 / 120
= 1/6

the function g is a transformation of f if g has a y-intercept at -1 which of the following functions could represent g
9514 1404 393
Answer:
A.
Step-by-step explanation:
The function f has a y-intercept of -5. The function g's y-intercept of -1 is 4 units up from that, so one way to represent g is ...
g(x) = f(x) +4
The required function is g(x) = f(x) + 4. Hence, Correct option is A.
Functions is the relationship between sets of values. e g y=f(x), for every value of x there is its exists in set of y. x is independent variable while Y is dependent variable.
According to the graph,
The given curve has y intercept at y = -5.
Which implies that when we add 4 to the function intercept shifts to y = -1 although it is the required intercept of new function g(x).
Thus, the required g is g(x) = f(x) + 4
