What is the slope of a line parallel to the line whose equation is y=3x + 4?
Answer:
The slope of any line parallel to y=3x+4 would be 3!
Step-by-step explanation:
When lines are parallel, they always have the same slope!
When lines are perpendicular, the slope would be the negative reciprocal!

there are 60 people in a choir
half of the people in the choir are women
the number of women in the choir is 3 times the number of men in the choir
the rest of the people in the choir are children
the number of children in the choir :the number of men in the choir =n:1
work out the value of n
Answer:
The value of n is 2.
Step-by-step explanation:
The total number of people in the choir = 60
Number of women in the choir = 30
Let the number of men in the choir be represented by x, so that;
Number of women = 3x
So that;
3x = 30
x = [tex]\frac{30}{3}[/tex]
= 10
The number of men in the choir is 10.
the number of children in the choir: the number of men in the choir = n:1
number of children in the choir = 60 - (number of women + number of men)
= 60 - 40
= 20
number of children in the choir = 20
Thus,
the number of children in the choir: the number of men in the choir = 20:10
= 2:1
The value of n is 2.
Answer:
20 men in the choir and 40 children

Aaron invested $570 in an account paying an interest rate of 7% compounded continuously. Assuming no deposits or withdrawals are made, how much money, to the nearest dollar, would be in the account after 8 years?
Answer:
The amount of money that would be in the account after 8 years is approximately $998
Step-by-step explanation:
The given parameters for the compound interest investment are;
The amount Aaron invested = $570
The interest rate of the investment = 7%
The mode of compounding of the interest = Continuously
The number of years the amount is invested = 8 years
For a compounded continuously interest rate, we have;
[tex]A = P \cdot e^{r \cdot t}[/tex]
Where;
A = The future value =The amount realized from the investment after the time of investment
P = The initial value = The principal amount invested
e = Euler's number = Mathematical constant
r = The interest rate = 7%
t = The time of investment = 8 years
Therefore, by substituting the known values, we have;
[tex]A = 570 \times e^{0.07 \times 8} \approx 997.883325[/tex]
The amount of money that would be in the account after 8 years to the nearest dollar = The future value of the investment = A ≈ 998
The amount of money that would be in the account after 8 years to the nearest dollar ≈ $998.

what is the equation of the line in the graph?
Answer:
y=-1x-2
Step-by-step explanation:
hope it helps ^^
Answer:
y = -x - 2
Step-by-step explanation:
Since we have a straight, linear line, the line follows the y = mx + b format
The line moves one unit down for every unit to the right, making m = 1
Since the line has a downward slope, m = -1
Since the line crosses the y-axis at -2, b = -2
Therefore, the equation is y = -1x - 2 or more simplified, y = -x - 2
what number is one hundred more than 890
Answer:
990
Do 100+890
its simple math
The number that is one hundred more than 890 would be,
⇒ 990
The process of combining two or more numbers is called the Addition. The 4 main properties of addition are commutative, associative, distributive, and additive identity.
Given that,
To find a number that is one hundred more than 890.
Let us assume that,
The number that is one hundred more than 890 = x
Hence, it can be written as,
⇒ x = 890 + 100
Solve for x,
⇒ x = 990
Therefore, the number that is one hundred more than 890 = 990

Line n is perpendicular to the y-axis. If the line contains point (0, -4), what is the equation of line n ?
Answer:
y=0x - 4
Step-by-step explanation:
perpendicular to the y-axis means parallel to the x-axis.
that would be a horizontal line and they have no slope. so m=0
(0, -4) is the y-intercept since the y intercept is when x is zero.

Given,
The total number of bacteria in lab dish is 1200
The population decreases 10% per day

Use the slope-intercept form to find the slope and y-intercept.
The slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept.
y = mx + b
Find the values of m and b using the form y = mx + b.
m = −3
b = 12
The slope of the line is the value of m, and the y-intercept is the value of b.
Slope: −3
intercept: (0, 12)
Any line can be graphed using two points. Select two x values, and plug them into the equation to find the corresponding y values.
Find the x-intercept.
To find the x-intercept(s), substitute in 0 for y and solve for x.
0 = −3x + 12
Solve the equation.
Rewrite the equation as −3x + 12 = 0.
−3x + 12 = 0
Subtract 12 from both sides of the equation.
−3x = −12
Divide each term by −3 and simplify.
x = 4
x-intercept(s) in point form.
x-intercept(s): (4, 0)
Find the y-intercept.
To find the y-intercept(s), substitute in 0 for x and solve for y.

Remove parentheses.
y = −3 ⋅ 0 + 12
Simplify −3 ⋅ 0 + 12.
y = 12
