Answer:
-3x> or equal to -30; answer number 1
Step-by-step explanation:
-3x> or equal to as the dot is filled in. and it's heading towards the negative which mean it's equal to or less than 10.
Also -3x/-30 = -x>-30/-1 when you divide by a negative flip the sign.
so x< or equal to 10.
or -3x> or equal to -30
Answer:
<em>x = 10; y = 20</em>
Step-by-step explanation:
8x + y = 100 (alternate exterior angles are congruent)
4x + y = 60 (corresponding angles are congruent)
Subtract the second equation from the first equation.
4x = 40
x = 10
Substitute x = 10 in first equation and solve for y.
8(10) + y = 100
y = 20
To rotate a figure 90 degrees counter clockwise, switch the X and Y coordinates, and then multiply the new X value by -1
Find the original points:
(2,2) becomes (-2,2)
(7,1) becomes (-1,7)
(8,-4) becomes (4,8)
Answer:
x = 3
Step-by-step explanation:
given
4(x - 8) + 10 = - 10 ← subtract 10 from both sides
4(x - 8) = - 20 ← divide both sides by 4
x - 8 = - 5 ← add 8 to both sides
x = 3
