Good morning ☕️
Answer:

Step-by-step explanation:
35r-21 < -35r+19
⇌ 35r + 35r < 19 + 21
⇌ 70r < 40
⇌ r < 40/70
⇌ r < 4/7

Answer: -2/5
Step-by-step explanation:
To find the slope, we set the function use y = mx + b forms.
2x + 5y = 10
5y = -2x + 10 Minus 2x in both side
y = -2/5x + 10/5 Divide 5 from both side
y = -2/5x + 2
In the y = mx + b, the m before variable x is always the slope, so -2/5 is the slope for 2x + 5y = 10.
Answer:
15ft
Step-by-step explanation:
the square root of 225 is 15, so the answer is 15ft
15×15=225
The solution is n= <u>+</u> 4i/√11
Step-by-step explanation:
step 1: 10n^2+n^2+16=0
step 2: 11n^2+16=0
step 3: 11n^2= -16
step 4: n^2= -16/11
step 5: taking square root on both sides,
n= √(-16)/√11 (square root of a negative number is a <u>complex term</u> 'i')
n= <u>+</u> 4i/√11
