eliminating y
x - y = -5
3x + y = 1
________ +
4x = -4
x = -1
eliminating x
• x - y = -5 ....... (x3)
3x + y = 1 ....... (x1)
• 3x - 3y = -15
3x + y =1
___________ -
-4y = -16
y = 4
A. (-1, 4)
Answer:
Hello first one is 4.
Second one is 8
Step-by-step explanation:
First one is f(0). It means you should put zero in the place of x
0 is less than 5 so you should put zero in x+4=f(x)
For the second one do like the first one.
I hope you understand
Answer/Step-by-step explanation:
1. ∠XVR = 180 - <XVW (angle on a straight line)
∠XVR = 180 - 55°
∠XVR = 125°
2. ∠RVS = <XVW (Vertical angles are congruent)
∠RVS = 55°
3. ∠WVS = ∠XVR (vertical angles are congruent)
∠WVS = 125°
4. ∠RST = <R + <RVS (exterior angle theorem)
<RST = 55 + 55
<RST = 110°
5. ∠RSV = 180 - (<R + <RVS) (sum of triangle)
∠RSV = 180 - (55 + 55)
∠RSV = 70°
6. ∠VSU = <RST (vertical angles are congruent)
<VSU = 70°
7. ∠UST = <RSV (vertical angles)
<UST = 70°
8. ∠TUS = 180 - (<UST + <T) (sum of triangle)
<TUS = 180 - (70 + 71)
<TUS = 39°
Answer:
56
Step-by-step explanation:
11*4=44
6*2=12
44+12=56
Answer:
Option B and C is correct
Step-by-step explanation:
<h3><u>Given</u>;</h3>
- Priya has 5 pencils, each x inches in length.
- Total length = 34.5 inches.
Now,
5 times x = 34.5
So,
5x = 34.5
34.5 ÷ 5 = x
Thus, 5x = 34.5 and 34.5 ÷ 5 = x are the answer
