1. I'm assuming you meant to type 0.2, 0.6, 1, 1.4...
In that case, it is increasing by 0.4, so the next three would be:
0.2 + (4-1)(0.4) = 1.8...
=> 1.8, 2.2, 2.6.
2. Here it's reducing by 0.25, so start with:
4 + (5-1)(-0.25) = 3...
=> 3, 2.75, 2.5
To solve the logarithmic inequality below, Braden
decides to first
create a table of values representing the left side of the inequality. Which statements accurately reflect Braden's inequality? Check all that apply.
The domain of the logarithmic expression is x < 2.
The solution set is the interval (5, 14).
When written as two inequalities and graphed, the graphs intersect at (5, 14).
When graphed, the overlapping shading extends to
positive infinity.
The ordered pair (32, 3) could be included in the
table.

Step-by-step explanation:
since the lines only intersect each other once there is one solution at the point (1,4)
Answer:
C - One solution: x = 1, y = 4
Step-by-step explanation:
The solution is where the lines intersect. We can see they only intersect at point, (1, 4), so the answer is C - One solution: x = 1, y = 4.

James has $10 in 5-cent and 10-cent coins in his change jar and counts 157 coins in total. How many 10-cent coins does he have?
Answer:
Step-by-step explanation:
Let the number of 5-cent coins he has be x and the number of 10-cent coins he has be y
x coins + y coins = 157 coins
(x × 5)cents + (y × 10)cents = $10
These two equations are true about the money he has, i.e
x + y = 157
5x + 10y = 1000
(We made the $10 into 1000 cents because the coins are in cents)
We can solve the above equations either simultaneously or through substituting.
Simultaneously:
(x + y = 157) × 5
5x + 10y = 1000
5x + 5y = 785
5x + 10y = 1000
Subtract the co-efficients in the equations
0x + -5y = -215
-5y = -215
y = 43
This means he has 43 10-cent coins.
PS: We get the number of 5-cent coins by subtracting 43 from 157, the total number of coins he has.
Substituting:
x + y = 157
5x + 10y = 1000
y = 157 - x
5x + 10(157 - x) = 1000
5x + 1570 - 10x = 1000
-5x = -570
x = 114 coins
157 - 114 = 43 coins
Thus there are 43 10-cent coins.
Answer:
46
Step-by-step explanation:
You would have 46 10-cent coins. First split it up into dollars, there are $10 and 10 dimes in each dollar. So if James has 157 coins you would need to first see how many coins he has in total. In total there are 100 dimes. We need to get to 157 coins so we'll need to break up some of the coins. So we keep turning the dimes into nickels until we get the number 157 for all the coins in total. So James has 46 10-cent coins.

Answer:
c² - 14cd + 49d²
Step-by-step explanation:
Given
(c - 7d)²
= (c - 7d)(c - 7d)
Each term in the second factor is multiplied by each term in the first factor, that is
c(c - 7d) - 7d(c - 7d) ← distribute both parenthesis
= c² - 7cd - 7cd + 49d² ← collect like terms
= c² - 14cd + 49d²

A rectangle has a length of (2x + 3) cm and a width of (x + 5) cm.
(a) Find an expression for the perimeter of the rectangle.
Answer:
P = 6x + 16
Step-by-step explanation:
the perimeter (P) of a rectangle is calculated as
P = 2l + 2w ( l is the length and w the width ) , then
P = 2(2x + 3) + 2(x + 5) ← distribute both parenthesis
= 4x + 6 + 2x + 10 ← collect like terms

Yuto and Riko went for a bike ride on the same path. When Riko left their house, Yuto was 5.25 miles along the path. If Yuto’s average speed was 0.25 miles per minute and Riko’s average speed was 0.35 miles per minute, then Riko will be behind Yuto when 0 ≤ t < 52.5, where t is time in minutes. Explain what this solution means and why t cannot be less than zero.
ANSWER:
The solution means that Riko will be behind Yuto from the time she leaves the house, which corresponds to t = 0, until the time she catches up to Yuko after 52.5 minutes, which corresponds to t = 52.5. The reason that t cannot be less than zero is because it represents time, and time cannot be negative.

What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
It is given that:
The measure of angle m is 7 degrees less than the measure of angle n.
m = n - 7 ...(I)
The sum of the measures of the two angles is 59°
m + n = 59 ...(II)
Solving the above two linear equations in two variables by substitution method:
n - 7 + n = 59
2n = 66
n = 33
m = 33 - 7 = 26
Thus, the measure of each angle are 33 and 26 if the measure of angle m is 7 degrees less than the measure of angle n.

If 3 superscript 2 x 1 baseline = 3 superscript x 5, what is the value of x?
The value of x for the considered algebraic equation is 4.
What are some basic properties of exponentiation?If we have [tex]a^b[/tex] then 'a' is called base and 'b' is called power or exponent and we call it "a is raised to the power b" (this statement might change from text to text slightly).
Exponentiation (the process of raising some number to some power) have some basic rules as:
[tex]a^{-b} = \dfrac{1}{a^b}\\\\a^0 = 1 (a \neq 0)\\\\a^1 = a\\\\(a^b)^c = a^{b \times c}\\\\ a^b \times a^c = a^{b+c} \\\\^n\sqrt{a} = a^{1/n} \\\\(ab)^c = a^c \times b^c\\\\a^b = a^c \implies b = c \text{ (if a, b and c are real numbers and } a \neq 1 \: and \: a \neq -1 )[/tex]
For this case, we have got the equation as:
[tex]3^{2x+1} = 3^{x+5}[/tex]
Using the property that: [tex]a^b = a^c \implies b = c \: \:(if \: a \neq 1 \: and \: a \neq -1)[/tex], we get:
[tex]2x + 1 = x + 5\\[/tex]
Solving it further:
[tex]2x + 1 = x + 5\\\\\text{Subtracting 1+x from both the sides}\\\\2x + 1 - (1+x) = x+5 - (1+x)\\x = 4[/tex]
Thus, the value of x for the considered algebraic equation is 4.

An equation that models the decline in the number of US farms is y=3,962,000e−0.02t where t is the number of years since 1960 and y is the number of farms.
The decline in the number of farms means there is a reduction in the number of farms
The number of US farms after 5 years is 3584818
How to determine the number of farmsThe equation that represents the number of farms is given as:
[tex]y=3962000e^{-0.02t[/tex]
After 5 years, the value of t is 5.
So, we have:
[tex]y=3962000e^{-0.02*5[/tex]
Evaluate the product
[tex]y=3962000e^{-0.1[/tex]

Answer:
y = 2x + 1/3
Step-by-step explanation:
Since the line is parallel to y = 2x - 5, its slope is also 2x, as parallel lines have the same slope, leaving you with y = 2x.
Since it intercepts the y-axis at 1/3, and y = 2x intercepts the y-axis at 0, you will now need to add a 1/3 to the end of the equation for it to intersect the y-axis at the right place.
Therefore, the equation is: y = 2x + 1/3
