If you eliminate obvious wrong answers you increase your chances of getting the question correct.
Notice the inequality signs are both "equal to" which means a solid boundary line. This means choice B and D can not be correct.
You can test a point that is exclusively in the shaded region of each graph.
x + 2y ≤ 4
-x -x solve for y by moving x term
2y ≤ -x + 4
÷2 ÷2 divide both sides of the inequality by 2
y ≤ -1/2x + 2 ← plot 2 on y-axis then move down 1 and right 2 put 2nd point
shade below the solid line
3x - y ≥ 2 when solved for y → y ≤ 3x - 2 (the inequality sign switched because in the process of solving for y I had to divide by a negative number)
plot -2 on the y-axis then move up 3 and to the right 1 put 2nd point
shade below the line
the answer is choice A only graph where they have shaded below both lines...use the y-intercept as a guide for shading above or below the line... shading where numbers are greater than the y-intercept is shading above the line and shading where numbers are less then the y-intercept is shading below the line
Circles have the equation (x-h)²+(y-k)²=r² with the center at (h,k) and radius r
so if you bring the equation into this form you can read everything off
x²+y²-4=0
x²+y²=4
(x-0)²+(y-0)²=2²
so the radius r=2
h=0,k=0 which means the center is at (0,0)
Answer:
Answer:16
Step-by-step explanation: 2x2 is 4
4x4. Is 16w
W stand for width
Step-by-step explanation:
Answer:
y = 1/2x - 6
Step-by-step explanation:
Key:
m = slope
b = y-intercept
Slope:
( 0 - - 6 ) / ( 12 - 0 )
( 6 ) / ( 12 )
1 / 2
y-intercept:
( -6, 0 )
