Answer: It would be 30
Step-by-step explanation:
The answer I gave you is for x.
Answer:
Line 3
Step-by-step explanation:
The problem's lines are:
Line 1. 5(x - 5) = 15
Line 2. 5x - 25 = 15
Line 3. 5x - 25 = 15 - 25
Line 4. 5x = -10
Line 5. 5x/5 = -10/5
Line 6. x = -2
The first error is in Line 3, where 25 was subtracted from just the right side, and where 25 should have been added to both sides instead.
Answer:
y= -7
Step-by-step explanation:
y=ax+b
Find a where a=y2-y1 /x2-x1
y2=13,y1=5 x2=5,x1=3
substituting the values
a=13-5/5-2
a=8/2
a=4
substituting a into the formular
y=4x+b
taking x and y values let say 3 and 5 for x and y
the equation becomes
5=4(3)+b
5=12+b
5-12=b
-7=b
substituting the values of a and b into the equation
y=4x-7
when x=0
y=4(0)-7
y=0-7
y=-7
so when x=0,y=-7
