Step-by-step explanation:
<u>Given inequality:</u>
<u>Verify if (-1, 1) is correct:</u>
- 7(-1) + 2(1) > - 5
- - 7 + 2 > - 5
- - 5 > - 5
False inequality, it is not the solution
Answer:
the answer is a
Step-by-step explanation:
y = -2x +1
y = x + 5
-2x+1=x+5
-3x = 4
x= -4/3
y = -1 1/3 + 5= 3 2/3
Area=length x width
A=lw
A=12 3/8
l=x
w=2 3/4
first, make your mixed numbers into improper fractions
12 3/8 --> 99/8
2 3/4 --> 11/4
then, set equal denominators
99/8 and 22/8
99/8=22/8x --plug in values
99/22=x --divide both sides by 22/8
convert improper fraction to mixed number
99/22 --> 4 11/22 --> 4 1/2
therefore, the length is 4 1/2 meters
answer is 1) y = - 3x^2 -7x + 4
