Answer:
The intersecting point is (-3,-2).
Step-by-step explanation:
The given equations are :
2x−y+4=0
2x−y=-4 .....(1)
x+y=-5 .....(2)
Adding equations (1) and (2).
2x+x = -4-5
3x=-9
x = -3
Put the value of x in equation (2).
-3+y=-5
y = -5+3
y = -2
Hence, the intersecting point is (-3,-2).
Answer:
x >=5 or x <=-3
Step-by-step explanation:
Solve an absolute value inequality
3|x-1| >= 12
Divide each side by 3
3/3|x-1| >= 12/3
|x-1| >= 4
Now there are two solutions
x-1 >= 4 or x-1 <= -4
Add 1 to each side
x-1+1 >= 4+1 or x-1+1 <= -4+1
x >=5 or x <=-3
Answer:
D
Step-by-step explanation:
Distribute 10 in the equation
10 x 3 + 10 x 4 = 70
For this case we have the following compound inequality:
11 <7 + 0.25t ≤ 15
We must solve this inequality for time.
We have then:
For 11 <7 + 0.25t:
11 <7 + 0.25t
11 - 7 <0.25t
4 <0.25t
4 / 0.25 <t
16 <t
For 7 + 0.25t ≤ 15:
7 + 0.25t ≤ 15
0.25t ≤ 15 - 7
0.25t ≤ 8
t ≤ 8 / 0.25
t ≤ 32
Therefore, the answer is:
16 <t ≤ 32
Answer:
16 <t ≤ 32
Clara has the desired length in more than 16 weeks, but up to 32 weeks.
