Answer:

-4x+15

Step-by-step explanation:

Two lines are perpindicular if their slopes are negative reciprocals

This means that our slope is -4x

Our equation so far looks like this

-4x+b=y

we can plug in (4, -1) and solve for b

-4(4)+b= -1

-16+b= -1

15=b

Which means our line is y= -4x+15

Marrrta [24]

Answer:

Step-by-step explanation:

Seashells collected before breakfast = 39

Seashells collected after breakfast = 2 and 1/3 = 2\frac{1}{3},

and 1/3 as a decimal = 0.3333

Add 2 to 0.3333 to get =2.3333 times

Therefore ,Seashells collected after breakfast = 2.3333*39 = 90.9987 ,which is roughly 91

Next, add 91 to 39 to get total; 91+36 = 127

The total number of Seashells Sierra collected were 127

Solve for x:(2 x + 3)/3 - 1 = 10
Put each term in (2 x + 3)/3 - 1 over the common denominator 3: (2 x + 3)/3 - 1 = (2 x + 3)/3 - (3)/3:(2 x + 3)/3 - (3)/3 = 10
(2 x + 3)/3 - (3)/3 = ((2 x + 3) - 3)/3:(-3 + 3 + 2 x)/3 = 10
Add like terms. 3 - 3 = 0:(2 x)/3 = 10
Multiply both sides of (2 x)/3 = 10 by 3/2:(3×2 x)/(2×3) = (3×10)/2
(3×10)/2 = (3×10)/2:(3×2 x)/(2×3) = (3×10)/2
(3×2 x)/(2×3) = (2×3)/(2×3)×x = x:x = (3×10)/2
10/2 = (2×5)/2 = 5:x = 3×5
3×5 = 15:Answer:  x = 15
