Answer:
Y = 4/5x + 0
Step-by-step explanation:
y - 4 = 4/5(x-5)
y-4=4/5x-4
y=4/5x-4+4
1)
g+4-3g=1+g
subtracting g from both sides
4-3g=1
subtracting 4 from both sides
-3g=-3
g=1
2)
-6a+3=-3(2a-1)
extending the right side
-6a+3=-6a+3
adding 6a to both sides
3=3
which is an identity
3)
0.5b+4=2(b+2)
extending the right side
0.5b+4=2b+4
subtracting 0.5 b from both sides
4=1.5b+4
subtracting 4 from both sides
0=1.5b
b=0
4)
8-(3+b)=b-9
subtracting 8 from both sides
-(3+b)=b-17
extending the left side
-3-b=b-17
adding b to both sides
-3=2b-17
adding 17 to both sides
14=2b
b=7
Answer:
Step-by-step explanation:
watermelon (w): 2
jackfruit (j): 4
durian (d): 4 x 2 = 8
5w + 12j + xd = 324
5 (2) + 12 (4) + x (8) = 324
10 + 48 + 8x = 324
58 + 8x = 324
8x = 324 -58
8x = 266
x = 33.25
Answer:
32
Step-by-step explanation:
The answers are 3 and -13
You need to plug 3 and -5 into x
By doing this, you get :
12 - 3^2 and
12 - (-5)^2
those expressions equal
12 - 9
12 - 25
So you get
3
-13
