Answer:
1) coordinates
2) slope
Step-by-step explanation:
The equation of a line is given by the two equations:
[tex]y=mx+b[/tex], where m is the slope and b is the y-intercept, or
[tex]y-y_1=m(x-x_1)[/tex], where x₁ and y₁ is the location of any point on the line, and m is the slope.
→ As such, we know that given the slope and the coordinates of any point on a line, we can write the line's equation.
We can also find the slope of a straight line between two points with the following equation:
[tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex], where m is the slope, x1 and y1 is the location of the first point, and x2 and y2 is the location of the second point. Remember: rise (y) over run (x).
→ So, given only two points, it is easy to find the equation of the line when you first find the slope.
0.2x + 1 = 1.6x + 3.1
What value of x satisfies the equation above?
Answer:
x = -1.5
General Formulas and Concepts:
Pre-Alg
Order of Operations: BPEMDASEquality PropertiesStep-by-step explanation:
Step 1: Define equation
0.2x + 1 = 1.6x + 3.1
Step 2: Solve for x
Subtract 0.2x on both sides: 1 = 1.4x + 3.1Subtract 3.1 on both sides: -2.1 = 1.4xDivide both sides by 1.4: -1.5 = xRewrite: x = -1.5Step 3: Check
Plug in x to verify it's a solution.
Substitution: 0.2(-1.5) + 1 = 1.6(-1.5) + 3.1Multiply: -0.3 + 1 = -2.4 + 3.1Add: 0.7 = 0.7PLEASE HELP

The highest temperature ever recorded in chicago was 105 degrees and the lowest was -27 degrees use absolute values to find the differences between the highest and lowest temperatures
Answer:
The differences between the absolute highest and the absolute lowest temperatures is 78°.
Step-by-step explanation:
It is provided that:
The highest temperature ever recorded in Chicago was 105° The lowest was -27°.Compute the differences between the absolute highest and the absolute lowest temperatures as follows:
[tex]\text{Difference}=|\text{Highest}|-|\text{Lowest}|[/tex]
[tex]=|105^{o}|-|-27^{o}|\\\\=105^{o}-27^{o}\\\\=78^{o}[/tex]
Thus, the differences between the absolute highest and the absolute lowest temperatures is 78°.

Answer:
5. a^3 + b^3 = (a+b)^3 - 3ab(a+b)
Step-by-step explanation:
(a+b)^3
= (a+b) (a+b) (a+b)
={(a+b) (a+b)} (a+b)
={a(a+b) + b(a+b)} (a+b)
=(a^2 + ab + ab + b^2) (a+b)
=(a^2 + b^2 + 2ab) (a+b)
=a^2(a+b) + b^2(a+b) + 2ab(a+b)
=a^3 + a^2b + ab^2 + b^3 + 2a^2b + 2ab^2
=a^3 + b^3 + 3a^2b + 3ab^2
=a^3 + b^3 + 3ab(a+b)
(a+b)^3 = a^3 + b^3 + 3ab(a+b)
(a+b)^3 - 3ab(a+b) = a^3 + b^3
a^3 + b^3 = (a+b)^3 - 3ab(a+b)

The slope of a line is -4, and the y-intercept is -3. What is the equation of the line written in slope-intercept form?
y = -4x - 3
y = 4x - 3
y = -4x + 3
Answer:
y= -4x+-3 = y=-4x-3
The rest are wrong.
Hi there! :)
We are given the slope of the line and its y-intercept.
So, we write the equation in slope-intercept form (y=mx+b)
m is the slope of the line, and b is the y-intercept.
y=mx+b
y=-4x-3
Hence, that's the equation (Option A)
Hope it helps. Use the comment section to clarify your doubts.

In 2003, the average attendance per game for a football team was about (1 × 104) + (9 × 103) + (9 × 102). What is this number in standard form?
show work
Answer:
1.99 * 10^4
Step-by-step explanation:
Here, we want to write the addition in standard form
= (1 * 10^4) + (9 * 10^3) + (9 * 10^2)
= 10,000 + 9000 + 900
= 19,900
so the number in standard form is;
1.99 * 10^4
If Jessica and Jonathan have created 19.64 cups of lemonade they sell the lemonade in serving of 1.25 cup. How many full serving will they be able to seel
Answer:
15 servings
Step-by-step explanation:
total amount of lemonade = 19.64 cups
lemonade per serving = 1.25 cups
total servings = 19.64 cups / 1 .25 cups = 15.712 servings
since you cannot sell a partially full serving, Jessica and Jonathan will only be able to sell 15 servings
in order for them to sell 16 full servings, they need to prepare 20 cups of lemonade (= 20 / 1.25 = 16)

If log (100ab^2) is expressed as a function of log b, the result would be:
1). 2 log a + 2 log b
2). 100 log a + 2 log b
3). 2 + log a + 2 log b
4). 2 + 2 log a + 2 log 6
Answer: Choice (3)
2 + log(a) + 2*log(b)
======================================================
Work Shown:
The log rules we'll use are
log(xy) = log(x)+log(y)log(x^y) = y*log(x)log(10) = 1, where the log is base 10So,
c = log(100ab^2)
c = log(100) + log(a) + log(b^2) ......... use log rule 1
c = log(10^2) + log(a) + log(b^2)
c = 2*log(10) + log(a) + 2*log(b) ......... use log rule 2
c = 2*1 + log(a) + 2*log(b) .................... use log rule 3
c = 2 + log(a) + 2*log(b)
Note: The use of rule 3 assumes that all logs shown are in base 10, which is the default assumed base. Rule 3 doesn't work for any general base. The more generalized rule is [tex]\log_b(b) = 1[/tex]. If b = 10, then we get rule 3 above.

y = b + 5x
(10,1)
Solve for b. Brainliest!
Answer:-49
Step-by-step explanation:(10,1)= (x,y) so we can see that x=10 and y=1. Now you put them in the equation 1=b+5*10. Then you get 1=b+50 and you put 50 to the left side and it becomes negative. 1-50=b . Therefore b=-49
Answer:
Step-by-step explanation:
y = 5x + b ⇒ b = y - 5x
(10, 1)
b = 1 - 5(10) = 1 - 50 = - 49
b = - 49
Quadrilateral ABCD has coordinated A(-4,3)B(-3,6)C(0,8)D(-2,5). Prove that quadrilateral ABCD is a parallelogram.
Answer:
The plotted dots connect to create a parallelogram with two sets of parallel lines in the second quadrant
Step-by-step explanation:
This might be a little tricky to explain but I will try my best.
A parallelogram is a four-sided plane rectilinear figure with opposite sides parallel.
The first pair of numbers is in the second quadrant the second set is also in the second quadrant a little bit up and to the right. The third set in the line a little up, the last set is again in the second quadrant and a little further down and near the middle.
Sorry if the answer isn't what you had hoped for, feel free to ask questions about it and I'll explain the best I can.
Anna's college tuition payment is automatically
withdrawn from a separate checking account used only
to pay tuition. At the beginning of the year, the balance
in this account was $13,287.48. After withdrawals each
month for a year, the balance is $1,449.84. How much is
Anna's college tuition payment each month? Estimate to
show that your answer is reasonable.
Answer: $986.47
Step-by-step explanation:
The total tuition fee for the year is;
= 13,287.48 - 1,449.84
= $11,837.64
The payment per month will therefore be;
= 11,837.64/12 months
= $986.47
