The line passing through the points (2, 4) and (5, 4) has which of the following slopes?
A. Undefined
B. Zero
C. Positive
D. Negative
Answer:
B
Step-by-step explanation:
The line would be a horizontal line and therefore the slope is 0. If the line was going vertical, then the slope would have been undefined.
What is an equation of the line that passes through the points (0, -1)(0,−1) and (6, 1)(6,1)?
[tex]slope = y2 - y1 \div x2 - x1[/tex]
[tex]1 - - 1 \div 6 - 0[/tex]
[tex]2 \div 6[/tex]
[tex]1 \div 3[/tex]
[tex]y = mx + c[/tex]
[tex]1 = 1 \div 3 \times 6 + c[/tex]
[tex]1 = 2 + c[/tex]
[tex]c = 3[/tex]
[tex]y = 1 \div 3x + 3[/tex]
Bricks are stacked according to the pattern shown below.
Each row contains one more brick than the row above it.
Part A
Determine a quadratic function to model the total number of bricks in the stack,
f(x), given a number of rows, m.
Answer:
Part A
The Quadratic Function to model the total number of bricks the stack is f(x) = x²
Part B
The number of bricks we will have for 50 rows is 2500 bricks
Step-by-step explanation:
Part A
Let the Quadratic Function to model the total number of bricks the stack, f(x), where x is the number of rows be f(x) = a·x² + b·x + c
We have;
When x = 0, f(x) = 0, therefore, f(0) = a×0² + b×0 + c = 0 + 0 + c = 0
∴ c = 0
When x = 1, f(x) = 1, therefore, f(1) = a×1² + b×1 + 0 = 1
∴ a + b = 1...(1)
When x = 2, f(x) = 4, therefore, f(2) = a×2² + b×2 = 4
∴ 4·a + 2·b = 4...(2)
Multiply equation (1) by 2, and subtract it from equation (2) gives;
4·a + 2·b - 2×(a + b) = 4 - 2 × 1
2·a = 2
a = 1
From equation (1), we have;
b = 1 - a = 1 - 1 = 0
b = 0
∴ f(x) = a·x² + b·x + c = 1·x² + 0·x + 0 = x²
Therefore, the Quadratic Function to model the total number of bricks the stack, f(x), where x is the number of rows be f(x) = x²
Part B
If there are 50 rows in the stack, then we have, x = 50
Therefore;
f(50) = 50² = 2500
The number of bricks we will have for 50 rows is f(50) = 2500 bricks

f(x) = 2x⁴ - 5x³ + 7x - 3
f(2) = 2(2^4) - 5(2^3) + 7(2) - 3
f(2) = 32 - 40 + 14 - 3
f(2) = 3

Answer:
25 - n
Step-by-step explanation:
n is a variable. It can represent any number. For example, 5 years ago, Mario would be 20 years old since 25-5 is 20.
So, if n is 8, you have to do 25 - 8 to find the answer to how old Mario was 8 years ago.
So his age n years ago, is 25 - n.

Nathaniel is building a rectangular shed. The length of the shed is 5 feet less than 3 times the width. The perimeter of the shed is 158 feet. What is the width of the shed?
Answer:
w = 21 feet
Step-by-step explanation:
The width of the given rectangular shed is such that the length of the shed is 5 feet less than 3 times the width formed the perimeter of 158 feet is 21 feet.
What is a rectangle?A rectangle is a geometrical figure in which opposite sides are equal.
The angle between any two consecutive sides will be 90 degrees.
Area of rectangle = length × width.
Let's say the length of a rectangle is L while the width is W.
According to the given, L = 3W - 5
The perimeter of the rectangle is given as 2( length + width)..
Perimeter = 2(L + W)
2(3W - 5 + W) = 158
4W - 5 = 79
W = 21 feet.
Hence "The width of the given rectangular shed is such that the length of the shed is 5 feet less than 3 times the width formed the perimeter of 158 feet is 21 feet".

Trail distance = 13 1/2 miles = 27/2 miles
Distance travelled before every each = 2 1/4 miles = 9/4 miles
The number of 4/9 miles in 27/2 miles.
= 27/2 / 9/4
= 27/2 x 4/9

find the equation of a line that is parallel to y= 4-x and cuts the Y axis at (0,1)
Answer:
y=-x+1
Step-by-step explanation:
y=-x+4
Substitute (0,1)
1=0+1
-1 is the gradient, if parallel then the gradient stays the same
Answer:
y = - x + 1
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept
y = 4 - x , that is y = - x + 4 ← in slope- intercept form
with slope m = - 1
The slope crosses the y- axis at (0, 1 ) ⇒ c = 1
y = - x + 1 ← equation of parallel line
