- 7 (4 - r) = 35 what's the correct answer?
Answer:
9
Step-by-step explanation:
- 7 (4 - r) = 35
First you need to do the parentheses
-7 times 4 is -28
-7 times -r is 7r
-28+7r=35
add 28 to both sides
7r=63
r=9
Answer:
r=9
Step-by-step explanation:
-28+7r=35, rearrange to put like terms together
7r=35+28, 7r=63, divide both sides by 7 to get r
r=63/7, r=9

Ginny is studying a population of frogs. She determines that the population is decreasing at an average rate of 3% per year. When she began her study, the frog population was estimated at 1,200. Which function represents the frog population after x years?
The function which represents the frog population after x years will be F(x) = [tex]1200 * (0.97)^{x}[/tex]
The population is decreasing at an average rate of 3% per year.
For decrease in population, if the rate is decreasing per year is r%, the initial population is P, after time x the equation to use would be:
net decrease = [tex]P * (\frac{100 - r}{100})^{x}[/tex]
r = Reduction
x = time duration
P = 1200
Reduction rate = 100 - 3 = 97%
Reduction rate will be 97% i.e. 0.97
Reduction after one year = 1200 * 0.97
Reduction after two years = 1200 * 0.97 *0.97
= 1200 * (0.97)²
Reduction rate after three years = 1200 * 0.97 * 0.97 * 0.97
= 1200 * (0.97)³
therefore,
Reduction rate after x years = [tex]1200 * (0.97)^{x}[/tex]
The function representing the frog population after x years is F(x) = [tex]1200 * (0.97)^{x}[/tex]

Write the equation of the line in slope-intercept form.
y-5x=16
The equation of the line in slope-intercept form is y = 5x + 16 .
The equation of a line in slope-intercept form can be written as follows,
y = mx + c equation 1
m in the above equation represents slope of the line and c represents the intercept.
The given equation is y - 5x = 16 .
To get the equation of the line in slope-intercept form we need to convert the given equation in the format of equation of a straight line i.e., equation1. So, now we will rearrange the given equation as
y - 5x = 16
On adding 5x on both sides in above equation, we will get
y = 5x + 16 equation 2
On equating equation 1 and equation 2, we will get
Slope of the line = m = 5
Intercept = c = 16

She pays a total of $6.58 for the cookies.
She buys 3 bags of oranges that each cost the same amount.
Write and solve an equation which can be used to determine xx, how much each bag of oranges costs.
The equation that can be used to represent the cost of oranges and cookies is; 6.58 + 3x = 22.39. Thus, the cost of each bag of orange is x = $5.27
How to Solve Algebra Word Problems?We are given;
Total Amount paid by Mila = $22.39.
Amount Mila paid for cookies = $6.58
Now, we are told that she also buys three bags of oranges. Now, if we denote the cost of each bag of orange to be x, then it means that;
Cost of 3 bags of oranges = $3x
Thus, we can write the equation to represent the cost of oranges and cookies as;
6.58 + 3x = 22.39
Subtract 6.58 from both sides to get;
3x = 22.39 - 6.58
3x = 15.81
x = 15.81/3
x = 5.27

Give an example of a sequence that is not an arithmetic sequence.
The sequence 2, 3, 5, 6..is example of the sequence which is not in arithmetic sequence AP.
What is the AP sequence (arithmetic progression)?In Arithmetic Progression (AP), the distinction between two arithmetical orders is a constant. It is also known as Arithmetic Sequence.
Then we'd run into some important words in AP, such as:
The first term (a)Common difference (d)Term nth (an)The total of first n terms (Sn)The AP can also be described using common distinctions, as shown below.
The following is the way to determine an AP's n-th term: an = a + (n − 1) × dThe formula for arithmetic progression sum is as follows: Sn = n/2[2a + (n − 1) × d].Common difference 'd' is d = a2 - a1 = a3 - a2 = a4 - a3 = ...... = an - an-1.Now, as per the question;
Consider any sequence. Let's say 2, 3, 5, 6..
Let's consider the first term is'a₁' = 2.
Let's consider 'a₂' = 3 is the second term.
Let's consider the third term is 'a₃' = 5.
Let's consider the fourth term be 'a₄' = 6
d₁ = a₂ - a₁
Substitute the values;
d₁ = 3 - 2 = 1 ........(equation 1)
Now take the other set;
d₂ = a₃ - a₂
d₂ = 5 - 3 = 2 .......(equation 2)
From the two equations 1 and 2. it is clear that the value of both common difference d₁ is not equal to d₂. Thus, the sequence considered is not in AP.
Therefore, the considered sequence 2, 3, 5, 6.. is not in AP.

y = -3x - 1, x < -0.5.y = x + 1, x ≥ -0.5.The function breaks at x = -0.5.
For item c, we have that:
y = -2x - 2, x < -3.y = 4, -3 ≤ x ≤ 0.5.y = 4x + 2, x > 0.5.The function breaks x = -3 and x = 0.5.

y = -2x - 2, x < -1.y = 2x + 2, x ≥ -1.The function breaks at x = -1.

What is the absolute value function?The absolute value function is defined by the following piecewise rule, depending on the input of the function:
|x| = x, x ≥ 0.|x| = -x, x < 0.It measures the distance of a point x to the origin, hence, for example, |-2| = |2| = 0.
In general terms, we have that:
|f(x)| = f(x), f(x) ≥ 0.|f(x)| = -f(x), f(x) < 0.Then, for item b, we have that:
|2x + 1| = 2x + 1, x ≥ -0.5.|2x + 1| = -2x - 1, x < -0.5.Then:
y = -3x - 1, x < -0.5.y = x - 1, x ≥ -0.5.The function breaks at x = -0.5.
For item c, we have that:
|2x - 1| = 2x - 1, x ≥ 0.5.|2x - 1| = -2x + 1, x < 0.5.|x + 3| = x + 3, x ≥ -3.|x + 3| = -x - 3, x < -3.Then:
y = -2x - 2, x < -3.y = 4, -3 ≤ x ≤ 0.5.y = 4x + 2, x > 0.5.The function breaks x = -3 and x = 0.5.
For item d, we have that:
|x + 1| = x + 1, x ≥ -1.|x + 1| = -x - 1, x < -1.Hence:
y = -2x - 2, x < -1.y = 2x + 2, x ≥ -1.The function breaks at x = -1.

Determine whether each sequence is arithmetic or geometric. Then identify the common difference or common ratio. 3/32, 3/16, 3/8, 3/4, 3/2, 3,6, . . . .
The sequence 3/32, 3/16, 3/8, 3/4, 3/2, 3,6, ... is a geometric sequence with common ratio 2.
To determine whether the sequence is an arithmetic or geometric one, we need to check how the consecutive terms relate to each other.
If it is an arithmetic sequence, then:
a(n) = a(n-1) + d
where d is the common difference.
If it is a geometric sequence, then:
a(n) = a(n-1) . r
where r is the common ratio.
The given sequence is:
3/32, 3/16, 3/8, 3/4, 3/2, 3,6, . . . .
Notice that
a(2) : a(1) = 3/16 : 3/32 = 2
a(3) : a(2) = 3/8 : 3/16 = 2
and so on

y = 2x - 1 , 3x - y = -1
By substitution, the solution of the system of equations, y = 2x - 1 and 3x - y = -1, is (-2 , -5).
A system of linear equations is a set of two or more equations which includes common variables. To solve system of equations, we must find the value of the unknown variables used in the equations that must satisfy both equations.
There are three methods that can be used to solve system of linear equations.
1. Elimination
2. Substitution
3. Graphing
Using substitution method, given two linear equations in x and y,
y = 2x - 1 (equation 1)
3x - y = -1 (equation 2)
Since the first equation is already expressed in y in terms of x, substitute the value of y to the second equation.
3x - y = -1 (equation 2)
3x - (2x - 1) = -1
3x - 2x + 1 = -1
Combining all terms containing the variable x on one side and the constants on the other side of the equality, and solving for x.
3x - 2x + 1 = -1
3x - 2x = -1 - 1
x = -2
Substitute the value of x in the first equation.
y = 2x - 1 (equation 1)
y = 2(-2) - 1
y = -4 - 1
y = -5
Hence, the solution of the given system of equations is (-2 , -5).

What is the total number of registered voters?
Percentage can be described as the fraction of a number expressed as an amount out of 100. Percentage is a measure of frequency. The sign that is used to represent percentages is %.
The first step is to determine the percentage of independent voters.
Percentage of independent voters : 100 - (percent of democrats + percent of republicans)
100 - (34% + 25%)
