Step-by-step explanation:
x=2 y=0
x= -2 y= -4
y=mx+b
b= 2
-4 = -2m +2
-2m= -6
m=3
y= 3x +2
.......
x=0 y=4
x=2 y= 2
y=mx+b
b=4
2=2m+4
2m= -2
m= -1
y = -x +4
Answer:
2+5x>47 or 2+5x=47
Just divide 1 5/8 by 1/3. You will get a decimal of something over four, but you can’t have part of a smoothie made in this problem so four smoothies is your answer!
Answer:
I Disagree cuz when you divide you are supposed to do it by flipping the numerator and denominator at the right and then multiply. So the correct answer should've been 4 and 1/2.
Now about that Brainly you promised...
Answer:
- 18. x = 24.5
- 19. x = 4
- 21. x = 10
Step-by-step explanation:
Corresponding sides have same ratio
Q18
- 7/6 = x / (27- 6)
- 6x = 7*21
- x = 147/6
- x = 24.5
Q19
- (x + 5)/15 = (5x + 1)/35
- (x + 5)/3 = (5x + 1)/7
- 7(x + 5) = 3(5x + 1)
- 7x + 35 = 15x + 3
- 15x - 7x = 35 - 3
- 8x = 32
- x = 4
Q21
- (x + 6)/24 = (2x - 2)/27
- (x + 6)/8 = (2x - 2)/9
- 8(2x - 2) = 9(x + 6)
- 16x - 16 = 9x + 54
- 16x - 9x = 54 + 16
- 7x = 70
- x = 10
