Answer:
a dilation by One-fourth and a translation
Step-by-step explanation:
For determining the sequence first we have to find out the scale factor which is shown below:
We can calculate the scale factor to obtain
![= \frac{1.5}{6} \\\\ = \frac{1}{4}](https://tex.z-dn.net/?f=%3D%20%5Cfrac%7B1.5%7D%7B6%7D%20%5C%5C%5C%5C%20%20%20%3D%20%5Cfrac%7B1%7D%7B4%7D)
Now as we know that the triangle XYZ and the triangle ABC are similar to each other but in the triangle XYZ is smaller in size and it is a shift to upward and right
Therefore the last option is correct
Hello, and thank you for posting your question here on brainly.
We have a trick in my school named "the cupid rule", where if you're subtracting a negative that's in parenthesis, we put a ♥ over the two negatives, and turn it into a positive, so now it's 7 + 15.
(it's 22)
Hope this helps! ☺♥
Answer:
The first graph.
Step-by-step explanation:
The graph of the function y = 2x + 7, is a straight line because it is a linear function, and has y-intercept of 7 and a slope of 3; so we are looking for a graph that has these characteristics.
From the 4 graphs, we see that the 1st graph has a slope of 3 and a y intercept of 7, and thus it is the correct answer.
Answer:
b = 2 or b = 7
Step-by-step explanation:
b/(b-7) - 2/b = 7/ (b-7)
b * b - 2(b - 7) = 7 * b
b^2 - 2b + 14 = 7b
b^2 - 9b + 14 = 0
(b - 2)(b - 7) = 0
b - 2 = 0; b = 2
b - 7 = 0; b = 7
Answer
b = 2 or b = 7
