5.25 - b ≥ 6.5
Solve for b:
5.25 - b ≥ 6.5
Subtract 5.25 from both sides:
-b ≥1.25
Multiply both sides by -1 ( and since you are multiplying by a negative you need to reverse the inequality sign as well).
b ≤ -1.25
Because the inequality sign contains equal to ( less than or equal to) the dot is solid and located at -1.25, because the inequality sign contains less than, the line/ arrow moves /points to the left.
The answer is the first one.
Answer:
so looks like they want you to solve each of them first, then plot them on the number lines.
1) x+8 >= 18
subtract 8 from each side
x >= 10
so for this one you would plot the point (a closed circle, since it's greater than or equal to) on the ten, and draw an arrow pointing to the right
2) x-1 > 6
add 1 to each side
x > 7
for this one you would plot an open circle on the 7 and draw an arrow to the right
3) -7+x >= -8
add 7 to each side
x >= -1
for this one you would plot a closed circle on the -1 and draw an arrow to the right
4) x-1 <= 3
add 1 to each side
x <= 4
for this one you would plot a closed circle on the 4 and draw an arrow to the left
Answer:
5x + 4y = 20
Step-by-step explanation:
(x1,y1) and (x2, y2)
(0, 5) and (4 ,0).
From equation of a line
y2 - y1/x2 - x1 = y - y1/ x - x1
Where x1 = 0, y1 =5 , x2 = 4 , y2 = 0
Imputing values,
0- 5/4-0 = y - 5 / x - 0
-5/4 = y -5/x
Multiply both sides by 4x I. E lcm of 4 and x
4x × -5/4 = y-5/x × 4x
-5x = 4(y - 5)
-5x = 4y - 20
Add 5x to both sides
-5x + 5x = 5x + 4y - 20
5x + 4y - 20 = 0
Add 20 to both sides
5x + 4y - 20 +20 = 0+20
5x + 4y = 20

Answer:
( 8x - 4 ) ( x - 2 )
Step-by-step explanation:
8x² - 12x - 8
8x² - 16x + 4x - 8
8x ( x - 2 ) - 4 ( x - 2 )
<u>( 8x - 4 ) ( x - 2 )</u>
Answer:
50%
Step-by-step explanation:
So, we divide by another 2! to cancel out double counting of two T's. Finally, if we divide all 6 different ways of getting exactly 2 heads (and 2 tails) in 4 flips by all possible outcomes 2 * 2 * 2 * 2 = 16 we would get the probability of exactly 2 heads in 4 flips.
