Answer:
150° and 210°
Step-by-step explanation:
1) to drow a circle with radius=1 in the system of coordinates like in the attached picture;
2) to mark point (-√3/2)≈-0.866 on X-axis (in the picture it is the point M);
3) to graph line AB through point M, the line AB || Y-axis and the points A and B are on the circle with radius=1;
4) to measure the angles ∠ROA and ∠ROB (the points are marked with red colour);
5) finally, m(∠ROA)=150°; m(∠ROB)=210°.
Set them up to equal each other
-7x + 2 = 9x - 14
16 = 2x
x= 8
plug in the x value into any of the two y equations
y= 9 (8) - 14
y=58
points (8, 58)
Answer: 0.6 or 3/5 cups of flour for 1 Egg
Step-by-step explanation:
If you need 3 cups of flour for 5 eggs, one egg would mean that it would be 3/5 cups of flour. If you convert it into fractions, the answer would be 0.6 cups of flour for one egg.
Answer:
-1/ 4
Step-by-step explanation:
y = 4x-3 has a slope of 4 because the equation is in slope intercept form
y = mx+b where the slope is m
Perpendicular lines have slopes that are negative reciprocals
-1/ 4 is the slope of a line that is perpendicular to y = 4x-3
