Ah, ok
RST
so RS+ST=RT
6x+12=72
minus 12 both sides
6x=60
divide both sides by 6
x=10
x=10
Answer: y = 3x - 2
the equation is y = ax + b (a ≠ 0)
see in the picture, the line passes through (0;-2) and (2;4)
because the line passes through (0;-2) => b = -2
the line passes through (2;4) => 2a + b = 4
have: b = -2
2a + b = 4
⇔ a = 3
b = -2
=> the equation is y = 3x - 2
Step-by-step explanation:
X+10=7x
10=6x
10/6=x
1 4/6 = x
1 2/3 =x
Hope this helps :)
Answer:
x = 15
Step-by-step explanation:
From the above diagram, we can see that the right angled triangle has been split into two by drawing a line from the altitude.
This would really in the following ratios or proportions below
25 : x = x : 9
25/x = x/9
Cross Multiply
x² = 25 × 9
x² = 225
x = √225
x = 15
Answer:
-1.5
Step-by-step explanation:
As you can see, to calculate the midpoint of 2 numbers, we sum them together and then divide by 2, we got:
(-6 + 3) / 2
= -3 / 2
= -1.5
Hope this help you :3
