Answer:
D) Perpendicular
Step-by-step explanation:
Red: 5y+4x=-30
Blue: y=5/4x-5
<span>What we need to do here to find out the total cost of the lawnmower is to add the sales tax to its standard price. So we have: FinalCost = 228 + 6/100 * 228 <=> FinalCost = 228 + 13.68 <=> FinalCost = $241.68. So the answer is A.</span>
Answer:
The other angle is 60°
Their ratio is 1 : 2
Step-by-step explanation:
Let us revise some special angles
A pair of complementary angles is two angles their sum is 90°
A pair of supplementary angles is two angles their sum is 180°
In the question
∵ One angle of the pair of complementary angle = 30°
∵ The sum of the two complementary angles = 90°
→ Subtract 30° from 90° to find the other angle
∴ The other angle = 90° - 30° = 60°
∴ The other angle is 60°
To find the ratio of them put them in the form of the ratio, then simplify the ratio to its simplest form
∵ Their ratio = 30 : 60
→ Divide both sides by 10
∴ Their ratio = 3 : 6
→ Divide both sides by 3
∴ Their ratio = 1 : 2
∴ Their ratio is 1 : 2
Answer:
y = - 6
Step-by-step explanation: You have to substitute 2 for x in order for you to get your solution.
y = - 4x + 2
y = - 4(2) + 2
y = - 8 + 2
y = - 6
- Remember, a negative times a positive, becomes a negative
Hope this helps you!!! :)
