Problem 1
Slope = 3/4
Y intercept = -5
You have the right idea for the slope, but I would use a slash as shown above to indicate a fraction. It looks like you're subtracting 3 and 4 based on what you typed in. Though that might be the division symbol (it's a bit blurry so I can't see it fully/clearly)

Problem 2
Answer: 14
The rate of change tells us how fast or slow that he's harvesting the crop. It's another way of saying his speed. The equation in this case is y = 14x+120 where 120 is the starting amount and its the y intercept. X represents the number of days, y represents the number of acres harvested.

Cranberry juice costs $6.30 per quart and apple juice costs $3.60 per quart. Terrence wants to know how many quarts q of cranberry juice he should mix with 4 quarts of apple juice to make cranberry-apple juice. He also wants to sell the juice at cost for $4.50 per quart. Which equation below represents the situation?
A. 3.60(q – 4) + 25.20 = 4.50q
B. 3.60q + 25.20 = 4.50(q + 4)
C. 6.30(q – 4) + 14.40 = 4.50q
D. 6.30q + 14.40 = 4.50(q + 4)
Answers
Answer:
The correct answer is D
Step-by-step explanation:
Cost of q quarts of Cranberry juice will be: $ 6.30q and cost of 4 quarts of apple juice will be $ (3.60×4)= $ 14.40. Total quarts of items would be q+4 , and he also wants to sell the juice at cost for $4.50 per quart. That means that the total cost to sell the juices will be $4.50(q+4) . Also, Total cost= Cost of q quarts of cranberry juice+cost of 4 quarts of apple juice.

Two points on the line are (0, 2) & (4,5).
Slope = (5 - 2)/(4 - 0)= 3/4

What is algebraic Expression?Any mathematical statement that includes numbers, variables, and an arithmetic operation between them is known as an expression or algebraic expression. In the phrase 4m + 5, for instance, the terms 4m and 5 are separated from the variable m by the arithmetic sign +.
We are aware that the Havertown newspaper had 80,000 readers in the year 2000 (when x=0) and 50,000 readers in the year 2010 (when x=10). With this knowledge, we can determine the slope of the line that depicts this situation:
slope = (change in y) / (change in x) = (50,000 - 80,000) / (10 - 0) = -3,000
So the slope of the line is -3,000.
We also have a point on the line: (10, 50,000). Using the point-slope form of the equation of a line, we can write:
y - 50,000 = -3,000(x - 10)
Now we just need to find the value that goes in the blank to complete the equation.
Because the line's slope is -3,000, y reduces by 3,000 for every unit increase in x.
We can see that a one-unit increase in x corresponds to a one-year increase in the time since x indicates the number of years from the year 2000. As a result, we might conclude that 3,000 fewer copies of the newspaper were distributed annually.
The point-slope equation is complete when:
y - 50,000 = -3,000(x - 10)
So the answer is -3,000.

Use synthetic division to find the expression for the area of the base of a rectangular prism with height x + 4 and volume x3 + 2x2 – 17x – 36.
2x2 – 9x
x2 + 6x – 24
x2 – 2x – 9
–4x2 + 8x + 36
Answers
The expression for the area of the base is x² – 2x – 9. Therefore, the correct answer is (C) x² – 2x – 9.
To use synthetic division, we first need to set up the divisor in the correct form. Since we are looking for the expression for the area of the base of the rectangular prism, we know that the volume of the prism is given by:
volume = (area of base) × (height)
We are given that the height is x + 4, and the volume is x³ + 2x² – 17x – 36. Therefore, we can write:
x³ + 2x² – 17x – 36 = (area of base) × (x + 4)
Now we can use synthetic division to find the expression for the area of the base. The divisor is x + 4, so we write:
-4 | 1 2 -17 -36
| -4 8 36
|-----------------
1 -2 -9 0
The last number in the bottom row is 0, which means that x + 4 is a factor of the polynomial. The other numbers in the bottom row give us the coefficients of the quotient polynomial. Therefore, we can write:
x³ + 2x² – 17x – 36 = (x + 4)(x² – 2x – 9)
So the expression for the area of the base is x² – 2x – 9. Therefore, the correct answer is (C) x² – 2x – 9.

Write an equation of a line that passes through the point Z (6, – 2) and is perpendicular to the line y=-1/3x + 2
Answers
Answer:
y = 3x - 20
Step-by-step explanation:
First, we have to find the slope of the equation. We can do by taking the opposite reciprocal of the slope of the original line.
The opposite reciprocal of-1/3 is 3/1 or 3.
So, the slope of our equation will be 3. Our equation so far is:
y = 3x + b.
To find b, or the y-intercept of the line, we can simply substitute the given coordinates into the equation. If we replace x with 6 and y with -2 and solve the equation, we can find the value of b.
-2 = 3(6) + b
-2 = 18 + b
-2 - 18 = b
b = -20
So the equation is,
y = 3x -20.
To check our equation, we can again substitute the coordinates into the equation and solve. If both sides are equal, then the equation is correct.
-2 = 6(3) - 20
-2 = 18 - 20
-2 = -2
The two lines are perpendicular if a 90° angle is formed when they
intersect.
The equation of the line that passes through point Z(6, -2) and is perpendicular to the line [tex]y = -\dfrac{1}{3} \cdot x + 2[/tex] is ; y = 3·x - 20
Reason:
The equation of the required line is, y = 3·x - 20
The given point is Z(6, -2)
Perpendicular to the line, [tex]y = -\dfrac{1}{3} \cdot x + 2[/tex]
Solution:
The slope of a line perpendicular to another line having a slope, m, is [tex]-\dfrac{1}{m}[/tex]
The slope of the given line is [tex]-\dfrac{1}{3}[/tex]
The slope of the perpendicular line is therefore;
[tex]m = -\dfrac{1}{\left(-\dfrac{1}{3}\right)} = \dfrac{3}{1} = 3[/tex]
The point and slope form of the equation of the given line is therefore;
y - (-2) = 3·(x - 6)
y + 2 = 3·x - 3×6 = 3·x - 18
y = 3·x - 18 - 2 = 3·x - 20
y = 3·x - 20
The equation of the line that passes through point Z(6, -2) and is perpendicular to the line [tex]y = -\dfrac{1}{3} \cdot x + 2[/tex] is therefore;
y = 3·x - 20
