Answer:
a
b
c
d
Step-by-step explanation:
Well lets look,
a)
If both slopes are different and have different y intercepts they have 1 solution.
So a has 1 solution
b)
Both slopes are different with different y intercepts.
1 solution
c)
Both slopes are different with different y intercepts
1 solution
d)
Different slopes different y intercepts
1 solution.
For proof look at the images below.
<em>Thus,</em>
<em>the answer is a,b,c, and d.</em>

Answer:
tan ∅ = 24 / 7
Step-by-step explanation:
cos ∅ = 7 / 25
sin^2 ∅ + cos^2 ∅ = 1
sin^2 ∅ + (7 / 25)^2 = 1
sin^2 ∅ = 1 - 49 / 625
sin^2 ∅ = 625 - 49 / 625
sin^2 ∅ = 576 / 625
sin ∅ = root 576 / 625
sin ∅ = 24 / 25
tan ∅ = sin ∅ / cos ∅
tan ∅ = 24/25 / 7/25
Therefore, tan ∅ = 24 / 7
OPTION 4. 24 / 7
Answer:
x = 25
Step-by-step explanation:
x = # of hrs he worked at his weekday job
w = # of hours he worked at his weekend job
25+ x = 40y = 40 - 25 = 15.
Therefore, Mia worked for 25 hours at his weekday job and 15 hours at his weekend job.
w + x = 40
20x + 18w = 770
18(x + w = 40) = 18x + 18w = 720
(20x + 18w = 770) - (18x + 18w = 720)
2x=50
x=25
Answer:
Yes. Its the same shape. It doesnt need to be the same size to be similar
Step-by-step explanation:
3000/100 = 30. When you go from Centimeters to Meters you divide by 100.
