Answer:
(- 5, 0) and (3, 0)
Step-by-step explanation:
Given
f(x) = x² + 2x - 15
To find the x- intercepts let f(x) = 0, that is
x² + 2x - 15 = 0 ← in standard form
(x + 5)(x - 3) = 0 ← in factored form
Equate each factor to zero and solve for x
x + 5 = 0 ⇒ x = - 5 ← left x- intercept
x - 3 = 0 ⇒ x = 3 ← right x- intercept
Answer:
BC 4 in
Step-by-step explanation:
The steps for construction;
- Using a ruler draw line AB 4 inches and label the end points A and B
- At point A , using a protractor, measure angle 60° and mark with point. Draw a line from A passing through this point extending to a length of 4 inches
- Mark that point C.
- Using the ruler, join point C and B and measure BC.
From calculation, length BC can be found by the formula;
------where a=b=4 in , cos A = cos 60°

BC = 4 in
Answer:
Arithmetic Sequence
Step-by-step explanation:
Because it would be a constant pattern
<u>Given</u>:
Given that the graph of a line with coordinates (-3,2) and (0,-2)
We need to determine the slope of the line parallel to the given line.
<u>Slope</u>:
The slope of the line can be determined using the formula,

Substituting the coordinates (-3,2) and (0,-2), we have;

Simplifying, we get;

Thus, the slope of the given line is 
<u>Slope of the parallel line:</u>
The parallel lines always have the same slope.
Thus, the slope of the parallel line is 
Hence, the slope of the parallel line is 
Therefore, Option c is the correct answer.
