Answer:
y = 3x + 4
Step-by-step explanation:
y = mx + b
b = y-intercept so:
b = 4
Since 4 is the y-intercept that means (0, 4).
To find slope:
m=(y2-y1)/(x2-x1)
m=(4 - 10)/(0 - 2)
m= (-6)/(-2)
m= 3
Slope-intercept:
y - y1 = m(x - x1)
y - 10 = 3(x - 2)
y - 10 = 3x - 6
y = 3x + 4
Just subtract the number infront of missing number to the opposing number
<span>4(2h + g)
</span><span>4h + 4h +3g + g
</span>2(4h + 2g)
4.75 is your answer because you add 2,8,10,12 and then divide it by 4 equals 8 . Then divide 2,8,10,12 by 8 gives you the total of 6,0,9,4 add all that gives you a total of 19/4 equals your answer of 4.75
X = # 5 inch stones, y = # 10 inch stones
5x + 10y = 145
y = x + 1
5x + 10(x + 1) = 145
5x + 10x + 10 = 145
15x = 135
x = 135/15
x = 9 <=== 9 five inch stones
y = x + 1
y = 9 + 1
y = 10 <=== 10 ten inch stones
