Yes for the first one, yes for the second one, and yes for the third one although your subtraction equation had the wrong year (its not 1847 its 1846) but the answer was right, 65.
4.3 x 10⁻⁵ Liters
0.043 mL
4.3 x 10⁻² mL
Answer:
Step-by-step explanation:
Given is the absolute value function.
<u>Observations:</u>
- It has a slope of ±√3 and the y- intercept of 2.
- There is no horizontal shift, so the the y-axis is the line of symmetry.
- The y-axis is also an angle bisector of the two lines.
- The foot P₁P₂ is parallel to the x-axis since it's perpendicular to the y- axis.
We need to find the coordinates of intersection of the line P₁P₂ with the y- axis (the point Y in the picture).
Consider the triangle AYP₂.
We know AP₂ = 5.
<u>The angle YAP₂ is:</u>
<u>The distance AY is:</u>
- AY = AP₂ cos 30° = 5*√3/2
<u>The distance from the x-axis to the point Y is:</u>
- 5√3/2 + 2, added the y- intercept of the graphed lines
<u>The coordinates of the point Y:</u>
Answer:
7x ≥ x + 6
A number signifies <em>x</em>.
Replace "a number" with x and then write out the inequality.
Answer:$2
Step-by-step explanation:Express as two equations . Lex x Be chocolate and y be cookies.
3x+2y=22
2x+3y= 18
Common factor of 6 so times first ran by 2, second ran by 3 . Eliminate.
