Does anyone know the pattern to this? Does anyone also know the slope to it and where the line intersects at the y-axis and the equation of the line?
Answers
Answer:
see explanation
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 )
Calculate m using the slope formula
m =
with (x₁, y₁ ) = (1, 3) and (x₂, y₂ ) = (3, 7) ← 2 ordered pairs from the table
m = =
= 2
The line crosses the y- axis at (0, 1 ) ← from table
Then c = 1
y = 2x + 1 ← equation of line

Answers
(x - 2) * (x + 5) = 18
x^2 + 5x - 2x - 10 = 18
x^2 + 3x - 28 = 0
(x + 7) * (x - 4) = 0
1. x = - 7
2. x = 4
The correct result would be x = - 7.
The solutions to the equation are x = - 7 and x = 4
What are equation solutions?
Equation solutions are the true values of x in the equation
The equation is given as:
(x - 2)(x + 5) = 18
Expand the equation
x^2 + 5x - 2x - 10 = 18
Subtract 18 from both sides
x^2 + 3x - 28 = 0
Factorize the expression
(x + 7) * (x - 4) = 0
Solve for x
x = - 7 and x = 4
Hence, the solutions to the equation are x = - 7 and x = 4

Now by increasing both the width and height by 9, you get: A = 1/2(9b)(9h) = 1/2(81)bh
You can see that the increase in area is 81 times the original.

Pennant 1 = base = 18 in ; length = 9 inches
Pennant 2 = base = 6 in ; length = x ?
9/18 = x/6
9*6 = 18x
54 = 18x
54/18 = x
3 = x
The length of the side of the smaller pennant is 3 inches.
Answer:the answer is 3inches
