Answer:
1. C. 4x + 40
2. a. - 2a + 10
3. d. 13x - 45
4. 2c-7d
5. b. -2z - 12
Step-by-step explanation:
1. 4(x+10) = 4x+4*10 = 4x+40
C
2. -2(a - 5) = -2*a -2*-5 = -2a+10
A
3. 10x + 3 (x-15)
10x + 3x -3*15
10x+3x-45
13x-45
D
4. -5(c+d) + 7c - 2d
-5c-5d + 7c-2d
-5c+7c -5d -2d
2c-7d
5. 2(2z + 4) - 2 (3z + 10)
2*2z +2*4 -2 *3z -2*10
4z+8 -6z-20
4z-6z+8-20
-2z-12

Answer: 97ft
Step-by-step explanation:
20+20= 40
30-3=27
40+30= 70
70+27= 97ft
No, it is not in the solution area for the system.
The point only works in one of the inequalities.
It doesn't work in the inequality: y > -1/2x+ 3
We can put it in to test it:
-7 > (-1/2)3 + 3
-7 > -1.5 + 3
-7 > 1.5 This is a false statement, therefore it is not part of the solution.
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.
