Terri wrote the equation using slope-intercept form for the line that passes through the points (4, 6) and (–2, 3).
Which best describes Terri’s first error?
In step 1, the slope of the line should be 1/2.
In step 2, she should have substituted the point (4, 6).
In step 3, she should have subtracted 4 from both sides of the equation.
In step 4, the m and b values should be switched.
Answer:
Step 1 is incorrect.
Step-by-step explanation:
The slope = difference of y values / difference of x values so Step 1 is incorrect. The slope is (6-3)/ ((4 - (-2)) = 1/2. He worked out x differences / y differences.
Answer: A: In step 1, the slope of the line should be 1/2.

98% of the mules who were surveyed said that stubbornness was a good character trait. If 343 mules gave this response, how many were surveyed in total?
Do a part over whole fraction
98% is a part of 100%
343 is a part of the number of mules who were surveyed in an unknown quantity.
You can set what you know into two proportions equal to each other:
[tex]\frac{98}{100} =\frac{343}{x}[/tex]
***x is the unknown value
Now you can cross multiply/butterfly
98x = 34300
Isolate x by dividing 98 to both sides of the equation
98x/98 = 34300/98
x = 350
This means that a total of 350 mules were surveyed

solve for x: 6(4x+5)=3(x+8)+3
Answer:
x=-1/7
Step-by-step explanation:
6(4x+5)=3(x+8)+3
Distribute
24x +30 = 3x+24 +3
Combine like terms
24x+30 = 3x +27
Subtract 3x from each side

Double the quotient of q and r
Answer:
(q/r)*2
Step-by-step explanation:
divide q and r, then multiply the result
The result of doubling the quotient of q and r is equal to 2 times the value obtained by dividing q by r.
To double the quotient of q and r, you would perform the following mathematical operation:
Double the quotient of q and r = 2 * (q / r)
In this expression, "q" and "r" are variables representing two numerical values. To get the result, you would divide "q" by "r" and then multiply the quotient by 2.

One cell phone plan charges $20 per month plus $0.15 per minute used. A second cell phone plan charges $35 per month plus $0.10 per minute used. Write and slice an equation to find the number of minutes you must talk to have the same cost for both calling plans.
Answer:
300 minutes
Step-by-step explanation:
Let
x----> the numbers of minutes used
y ---> the cost per month
we know that
First cell phone plan
y=0.15x+20 ---> equation A
Second cell phone plan
y=0.10x+35 ---> equation B
equate the equation A and equation B
0.15x+20=0.10x+35
Solve for x
0.15x-0.10x=35-20
0.05x=15
x=15/0.05
x= 300 minutes
Find the cost y
y=0.15(300)+20 =$65
That means
For x=300 minutes
The cost for both calling plans is y=$65

A coin is tossed twice. Let H represents heads, T represents tails, and the combination of the two letters represent the outcome of both tosses (e.g., if the coin landed heads on the first toss and tails on the second, we'd represent that with HT). Which of the following sets includes all possible outcomes of both tosses?
Answer:
{HH, HT, TH, TT}
Step-by-step explanation:
The set of all possible outcomes in tossing a coin twice is;
{HH, HT, TH, TT}
In the first toss the coin may land Heads. In the second toss the coin may land Heads or Tails. This can be represented as;
HH, HT
Heads in the first and second tosses. Heads in the first toss followed by a Tail in the second toss.
In the first toss the coin is also likely to land Tails. In the second toss the coin may land Heads or Tails. This can be represented as;
TH, TT
Tails in the first toss followed by a Head in the second toss. Tails in the first and second tosses.
Combining these two possibilities will give us the set of all possible outcomes in tossing a coin twice is;
{HH, HT, TH, TT}

Identify the function in which y varies directly with x
Answer:
y = kx
Step-by-step explanation:
You'll need to share the possible answer choices in all future posts.
A function in which y varies directly with x has the form
y = kx, where k is the constant of proportionality.
With more data, it'd be possible for you and me both to identify this constant.
To identify if a function represents a direct variation relationship between \( y \) and \( x \), we need to determine if the function can be written in the form \( y = kx \), where \( k \) is a non-zero constant known as the constant of variation.
Here are the steps to determine if a function shows that \( y \) varies directly with \( x \):
1. Have a function \( f(x) \) to test. The function should be expressed in terms of \( x \).
2. Attempt to write the function in the form \( y = kx \).
3. Analyze the function:
- If there are no constant terms (that is, no term without \( x \)) and the only term is a multiple of \( x \), then the function shows direct variation. The coefficient of \( x \) is the constant \( k \).
- If there is a constant term not involving \( x \) (other than when \( x = 0 \)), or if \( x \) is raised to a power other than 1, then \( y \) does not vary directly with \( x \).
Let's look at a few examples:
**Example 1**: \( f(x) = 3x \)
This function is in the form \( y = 3x \), which matches the direct variation form \( y = kx \). Here \( k = 3 \). Therefore, \( y \) varies directly with \( x \).
**Example 2**: \( g(x) = 5x^2 \)
\( g(x) \) does not show direct variation because it does not have the form \( y = kx \); instead, \( x \) is raised to the second power, so it cannot represent a direct variation.
**Example 3**: \( h(x) = -2x + 1 \)
\( h(x) \) has a constant term, \( +1 \), which means it does not match the form \( y = kx \) for direct variation since \( y \) should have no constant term other than the coefficient of \( x \). Thus \( y \) does not vary directly with \( x \).
**Example 4**: \( j(x) = \frac{1}{4}x \)
\( j(x) \) reflects a direct variation. The function can be written as \( y = \frac{1}{4}x \), so \( y \) varies directly with \( x \) with a constant of variation \( k = \frac{1}{4} \).
In conclusion, to determine if \( y \) varies directly with \( x \) within a given function, you only need to inspect the function's form to ensure it is a linear equation with a slope \( k \) and no constant term (other than 0 when \( x = 0 \)).
Maria wrote the equation log(x/2)+log(20/x2) What is the solution to Maria’s equation?
Answer:
log x - log 2 + log 20 - 2 log x
Step-by-step explanation:
We need to solve the equation:
[tex]log(\frac{x}{2}) + log(\frac{20}{x^2})[/tex]
We know that log(x/y) = log x - log y and
log(x^2) = 2logx
Solving we get:
[tex](log x - log 2) + (log20 - log x^2)\\(log x - log 2) + (log20 - 2 log x)[/tex]

The expanded expression in standard form for the given equation is [tex]\(25x^2 + 30x + 9\).[/tex]
To expand the expression [tex]\((5x + 3)^2\)[/tex], we use the distributive property, which states that for any real numbers [tex]\(a\), \(b\), and \(c\):[/tex]
[tex]\((a + b)^2 = a^2 + 2ab + b^2\).[/tex]
In this case,[tex]\(a = 5x\)[/tex] and[tex]\(b = 3\)[/tex]. Substituting these values into the formula, we get:
[tex]\[(5x + 3)^2 = (5x)^2 + 2(5x)(3) + 3^2\][/tex]
Now, let's compute each term:
1.[tex]\( (5x)^2 = 25x^2 \) (since \((a)^2 = a \times a\)).[/tex]
2. [tex]\(2(5x)(3) = 30x\) (by multiplying \(2ab\) where \(a = 5x\) and \(b = 3\)).[/tex]
