Find the x and y intercepts for the equation 3x-2.5y = 30.
2 answers:
Answer: x-int = 10 and y-int = -12
Explanation:
Find x intercept:
To find x intercept set y = 0
3x - 2.5(0) = 30
3x = 30
x = 10
Find y-int:
Set x = 0
3(0) - 2.5y = 30
-2.5y = 30
y = 30/-2.5
y = -12
Answer:
x=0.833....y+10 (its a repeating 3)
y=1.2x−12
Step-by-step explanation:
for x is:
Add 2.5y to both sides.
3x−2.5y+2.5y=30+2.5y
3x=2.5y+30
Divide both sides by 3
x=0.833333y+10
for y is:
Add -3x to both sides.
3x−2.5y+−3x=30+−3x
−2.5y=−3x+30
Divide both sides by -2.5.
y=1.2x−12
hope this helps

Answer: 5
Step-by-step explanation:
f(x)=2x+1
f(2)=2(2)+1 Subtitube 2 for x
f(2)=4+1
f(2)=5
Answer:
Your answer is C :)
Answer:
Steps
-x/3 >5
Multiply both sides by 3
3(-x/3)>5.3
Simplify
-X> 15
Multiply both sides by - 1 (reverse the inequality)
(-x)(-1)<15(-1)
Simplify
X< -15
so C is the answer
