In four weeks, he would be able to type 35 words a minute. See how it goes up two words per week. He started with 27 words, then after one week, it was 29, and after two weeks, it was 31, so after three weeks, 33, and in four weeks, 35. See the pattern? It counts by twos.
Answer:
Step-by-step explanation:
x and y are proportional.
Let x = 45 and y = 5.
Solve for r (constant of proportionality).
Divide both sides by 45.
Simplify and switch sides.
Answer:
y = 3x - 1
Step-by-step explanation:
Let's start with the two points.
y = mx + b
-19 = -6m + b
5 = 2m + b
Subtract the first from the second.
24 = 8m
m = 3
5 = 2*3 + b
b = -1
Answer:
Step-by-step explanation:
<u><em>The image and a pre-image after dilation with coefficient 1 are congruent.</em></u>
(-2, 1) x is negative
(3, -4) x is positive
(-4, 6) x is negative
(1, -3) x is positive
hope this helps!
