Answer:
Dionne is correct
Step-by-step explanation:
x=1 y=x+1 for example: if x=33 y would = 34
The correct statement is " It is a function: y = x + 1 for all in the domain."
Option D is the correct answer.
What is a function?A function has an input and an output.
A function can be one-to-one or onto one.
It simply indicated the relationships between the input and the output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have,
(1, 2), (3, 4), (5, 6), (100, 101)
We can make a function.
y = mx + c
Now,
Take two ordered pairs.
(1, 2) and (3, 4).
And,
m = (4 - 2) / (3 - 1)
m = 2/1
m = 1
Now,
(1, 2) = (x, y)
2 = 1 x 1 + c
2 - 1 = c
c = 1
Now,
y = x + 1
So,
The relation is a function and the function is y = x + 1.

Given:
The table of values is:
x y
-4 3
0 8
4 13
8 18
To find:
The slope of the line that described by the data in the table.
Solution:
Consider any two points from the given table.
Let the two points are (0,8) and (4,13). So, the slope of the line is
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
[tex]m=\dfrac{13-8}{4-0}[/tex]
[tex]m=\dfrac{5}{4}[/tex]
[tex]m=1.25[/tex]
Therefore, the slope of the line described by the data in the table is 1.25.

A triangular road sign has a height of 3 feet and a base of 2.5 feet. How much larger in area is this sign than one with a height of 2.5 feet and a base of 3 feet?
Answer:
Not larger or smaller; the areas are the same
Step-by-step explanation:
Recall that the formula for the area of a triangle of base b and height h is
A = (1/2)(b)(h).
In the first case, h = 3 ft and b = 2.5 ft. This results in an area of 3.75 ft^2.
In the second case, h = 2.5 ft and b = 3 ft. The area is the same: 3.75 ft^2.
This is because A = (1/2)(b)(h) has the same value regardless of the order in which b and h are used as multipliers.
There is no difference in the areas of the two signs. The areas are the same.

David invested $220 in an account paying an interest rate of 1.7%
compounded continuously. Assuming no deposits or withdrawals are
made, how much money, to the nearest ten dollars, would be in the
account after 10 years?
Answer:
260 dollars
Step-by-step explanation:
The amount after 10 years will be $260.
What is compound interest?The interest that is calculated using both the principal and the interest that has accrued during the previous period is called compound interest. It differs from simple interest in that the principal is not taken into account when determining the interest for the subsequent period with simple interest. Compound interest is commonly abbreviated C.I. in mathematics.
Given amount invested = $220
rate = 1.7% compounded annually
time = 10 years
the amount is given by
A = p[tex](1 + \frac{r}{n} )^{nt}[/tex]
r = 1.7% = 0.017
n = 1 for compounded annually
t = 10 years
p = $220
A = 220(1 + 0.017)¹⁰
A = $260.39
A = $260
Hence the amount is $260.

A, B, C and D are points on the circumference of the circle, centre O.
DOB is a straight line and angle DAC = 58°.
Find angle CDB.
Answer:
Angle CDB = 32
Step-by-step explanation:
Here, we want to find the measure of CDB
Mathematically;
angle DCB = 90
This is because angle at the center is twice the angle at the circumference
Also;
angle CAD = angle CBD = 58
This is because they are angles in the same segment
Furthermore;
CDB + 90 + 58 = 180
This is because sum of angles in a triangle is 180
CDB = 180-90-58
CDB = 32
