Answer:
19
Step-by-step explanation:
3x+4 while x is 5 means (3*5)+4 so 15+4=19
If that's not what you wanted I am sorry.
Answer:
A, B, D and F.
Step-by-step explanation:
Rin spends $20 every week on drum lessons.
If:
d = total amount of dollars Rin spends
w = number of weeks
Then: d=20w
w is the independent variable while d is the dependent variable. A change in w will lead to a change in d. Therefore:
(A)The independent variable causes a change in the dependent variable.
(B)The equation is d = 20w.
From the equation: d=20w
When w=1, d=$20
When w=2, d=$40
When w=3, d=$60
When w=4, d=$80
This tallys with the values in Option F.
Therefore:
(D)As the number of weeks increases, the total dollars Rin spends increases.
The correct options are: A, B, D and F.
Answer:
y = -1|x+1| +1
Step-by-step explanation:
The vertex form of an absolute value equation is y = a* |x-h| +k
a = -1 because it opens downwards with a slope of ± 1. Next it's vertex is at (-1,1). So replace h with -1 and k with one.
y = -1|x+1|+1
<u>p</u><u>=</u><u>7</u><u>0</u><u>°</u>
<u>q</u><u>=</u><u>3</u><u>2</u><u>°</u>
<u>r</u><u>=</u><u>3</u><u>8</u><u>°</u>
Answer:
Solution given:
r=38°[inscribed angle on a same arc are equal]
p=½*140°=70°[inscribed angle is half of the central angle]
<OBA=38°[base angle of isosceles triangle]
again
<C=<B[inscribed angle is half of the central angle]
70°=<OBA+q
70°=38°+q
q=70°-38°
q=32°
