The correct options regarding the functions are given as follows:
1. C. y = -2x - 7/9, m = -2, b = -7/9.
2. A. y = 1400x + 5000, 10,600 lbs.
3. A. t = 0.75m + 12, $23.25.
4. A. y = (x - 2) - 3.
5. B. 302.5 miles.
Item 1In slope-intercept formula, a linear function is given as follows:
y = mx + b.
In which:
m is the slope.b is the y-intercept.For this problem, the equation is:
-18x - 9y = 7.
Then:
9y = -18x - 7
y = -2x - 7/9, which slope -2 and intercept -7/9.
Thus option C is correct.
Item 2The table represents a linear function, in which:
The initial value is the intercept of b = 5000.Each week, the amount increases by 1400, hence the slope is of m = 1400.Thus the function is:
y = 1400x + 5000.
In four weeks, x = 4, hence the amount is of:
y = 1400(4) + 5000 = 10600.
Which means that option A is correct.
Item 3Also a linear function, in which:
The intercept is the flat fee of $12.The slope is the cost per mile of $0.75.Hence the function is:
t = 0.75m + 12.
For 15 miles, the cost is given as follows:
t = 0.75(15) + 12 = $23.25.
Which means that option A is correct.
Item 4In this graph, we have a concave up parabola with vertex at (2,-3), hence the rule is:
y = (x - 2) - 3.
Which means that option A is correct.
Item 5The distance function after t hours is given by:
d = 45t + 100.
Hence, after 4.5 hours, as 1/2 = 0.5, the distance is of:
d = 45(4.5) + 100 = 302.5 miles.
Which means that option B is correct.

option BA chord of a circle is 56cm long. The distance of the chord to the centre of the circle is 20cm. a) calculate the radius of the circle b) calculate the length of a chord which is 24cm from the center of the circle.
Answers
Answer:
a) 34.4 cm,b) 49.4 cmStep-by-step explanation:
The distance from the center to the chord is the perpendicular bisector of the chord.
The three segments form a right triangle:
The radius - hypotenuse,The half-length of the chord - leg,The distance to the chord - another leg.a) Use Pythagorean to find the radius:
r² = (56/2)² + 20²r² = 28² + 20²r² = 1184r = √1184r = 34.4 cm (rounded)b) Let the half-chord is x cm long. Use Pythagorean to find the missing leg:
34.4² = x² + 24²1184 = x² + 576x² = 1184 - 576x² = 608x = √608x = 24.7 cm (rounded)The length of the chord is:

Answers
The value of X = 21 .
What is perimeter?The length of every closed shape's perimeter is its whole perimeter. This rectangular farm has two sides, with l being the bigger side and b being the smaller side. His farm's circumference may be calculated by adding the lengths of its four sides. Total distance = 2l + 2b (l + b + l + b). In light of this, a rectangle's perimeter is equal to 2 (l + b) units. The complete distance around a shape is referred to as its perimeter. It is any two-dimensional geometric shape's perimeter or outline length. Depending on the measurements, the perimeter of multiple figures may be equivalent. Consider a triangle that is constructed from an L-length wire as an example.

STEP 1: Write the given function.
[tex]f(x)=\frac{1}{(x+3)}-2[/tex]STEP 2: Explain the means to use to find the required values
Since we were given a graph and can not use a caculator, we will be using the graph to get the values.
STEP 3: Plot the given function on a graph
STEP 4: Get the domain of the function
Domain: The domain is all x-values or inputs of a function. The domain of a graph consists of all the input values shown on the x-axis.
[tex]\begin{gathered} The\text{ domain from the graph is given as:} \\ x<-3\text{ or }x>-3 \\ \text{The interval notation is given as:} \\ (-\infty,-3)\cup(-3,\infty) \end{gathered}[/tex]STEP 5: Get the Range of the function
The range is all y-values or outputs of a function.

8x^2+8x-22 In (x-p)^2=q
Answers
The given function 8x^2+8x-22 rewritten using the completing the square method is (x+1/2)^2 = 3
Completing the square methodBy altering the equation's form so that the left side is a perfect square trinomial, a quadratic equation can be solved using the "Completing the Square" approach.
Given the quadratic equation below;
8x^2+8x-22 = 0
This can be simplified into the equation below;
8x^2+8x-22 = 0
4x^2+4x-11 = 0
Add 11 to both sides of the equation
4x^2+4x-11 + 11= 0 + 11
4x^2+4x = 11
Factor out 4x from the expression;
4(x^2+1) = 11
(x+1/2)^2 = 11/4 + 1/4
(x+1/2)^2 = 12/4
(x+1/2)^2 = 3
Hence the expression in the form of (x-p)^2=q is (x+1/2)^2 = 3

What is meant by the equation of a straight line?A straight line's general equation is y = mx + c, where m denotes the gradient and y = c denotes the point at which the line crosses the y-axis. On the y-axis, this value c is referred to as the intercept. Y = mx + c represents the equation of a straight line with gradient m and intercept c on the y-axis.
The equation of a straight line is:
y = mx + b where m is the slope and b is the y-intercept.
Therefore, the equation for this line is:
y = (1/3)x - 2
To graph it we can identify two points on the line and connect them.
If x = 0, then y = -2 this is the y-intercept given in the problem.
If x = 6, then y = 0 this is the x-intercept

Mr. Coffey bought a house for $195,000. He made a 20% down payment. The interest rate is 5.25% for 30 years. How much does he need to borrow? What is his monthly payment?
Answers
Explanation:
Mr. Coffey bought a house for $195,000 with a 20% down payment.
A 20% down payment, would be 0.20, so $195,000 times 0.20 equals $39,000. Then $195,000 - $39,000 = $156,000.
He bought the bouse for $156,000.
5.25% is 0.525, because you move the decimals back. Understanding the total cost of the house is $156,000 now, we can do $156,000 times 5.25% (0.0525) which equals $8,190.
He would pay $8,190 every 30 years. (if this was the interest rate.)
Assuming if the cost was 20% down payment with the 5.25% interest rate then it would have been: $39,000 times 5.25% = 2047.5.
He would pay $2,047.50 every 30 years. (if this was the interest rate.)
There was no context between the interest rate, so let's assume the obvious which is $2,047.50 every 30 years.

12-gon → An interior angle measures 150°
18-gon → An interior angle measures 160°
What is the sum of interior angles of a Polygon?The formula for sum of interior angles of a Polygon is;
S = (n - 2) * 180
where n is number of sides of polygon. Thus;
1) For a 15 sided polygon;
Sum = (15 - 2) * 180
Sum = 13 * 180
Sum = 2340
Sum of exterior angles of a polygon is; 360°
Thus, external angles = 360/15 = 24°

Answers
The number of hamburger is 350 and the number of cheeseburger is 282.
How to illustrate the information?It should be noted that an expression is simply used to show the relationship between the variables.
In this case, the local hamburger shop sold a combined total of 632 hamburgers and cheeseburgers on Saturday and there were 68 fewer cheeseburgers sold than hamburgers.
Let Cheeseburger = x
Hamburger = x + 68
This will be:
x + x + 68 = 632
2x + 68 = 632
2x = 632 - 68
2x = 564
x = 564/2
x = 282
Cheeseburger = 282
Hamburger = x + 68 = 282 + 68 = 350
