-12(x+5)=144
(use distributive property) -12x+ (-60)=144
+60 +60
-12x=204
-204 -204
-12x-204=0
+12x +12x
-204=12x
-204/12 12x/12
-17=x
x=-17
Answer:
2/5 or 0.4
Step-by-step explanation:
First we have to make equation into the gradient slope form :
y=mx+c m is gradient and c is y-intercept
15y-6x=8
First we add 6x to both sides :
15y = 6x+8
Now we divide both sides by 15 :
y = 6x+8 / 15
Split the fraction on the right :
y = 6x/15 + 8/15
6x/15 = 6/15x
Our gradient will be 6/15 = 2/5 or 0.4
Hope this helped and have a good day
Answer:
slope= 1/2x-3
Step-by-step explanation:
Rise / run + the y intercept
Answer: -4,-1.5,1,3.5,6,8.5
Step-by-step explanation: You can check that the difference of any of its consecutive terms is always equal to 2.5.
8.5 - 6 = 2.5
-1.5 - (- 4) = 2.5
3.5 - 1 = 2.5
Answer:
$120
Step-by-step explanation:
✓An expression for this can be written as
f(n) = 20(n)
Where n= number of weeks of the lesson.
✓Then the cost for 6 weeks of lessons will be f(6)
f(6) = 20(6)
=$120
Hence, The cost is $120
