Answer:
B. Domain is left to right so the left point is solid on 2 and the right is solid on 8. The solid point means it can also be equal to.
Answer:
Scale factor of 1.6.
Step-by-step explanation:
The triangle is dilated and the images is an enlargement of the pre-image. This means all angles of the triangles are congruent and these form similar triangles. Because they are similar triangles which have been dilated, they have a common ratio known as the scale factor between their side lengths. The scale factor here is 1.6 and can be found by using the ratio 0.8/0.5 = 1.6.
Answer:
Step-by-step explanation:
One is given the following equation.
The problem asks one to find a line that is parallel to this one, and passes through the point: . The equation of the given line is in the standard format. The easiest approach to solve this problem is to change the equation of the given line into the slope-intercept format. The solve intercept format follows the following general equation:
Where (m) is the slope of the line and (b) is the y-intercept. Manipulate the given equation such that it follows this format:
One property of parallel lines is that they have the same slope. Therefore, if one uses the slope-intercept format to represent the slope of the parallel line, then one can state the following:
Substitute a given point on this line () , and solve for (b) to find (b):
Simplify,
Inverse operations,
Substitute this back into the equation in slope-intercept form to find the equation of the parallel line:
Answer:
