Answer:

p = -3/4b -3/4

Step-by-step explanation:

Vectors are perpendicular when their dot product is zero.

A·B = p(4) +b(3) -3(-1) = 4p +3b +3

We want this to be zero, so ...

4p +3b +3 = 0

4p = -3b -3

p = -3/4b -3/4 . . . . the value of p that makes A⊥B

For math Equations what is 4x + 5 = x + 8??

vfiekz [6]

Answer:

x = 1

Step-by-step explanation:

To solve for a variable, you need to get the variable on one side of the equation, and by itself.

4x + 5 = x + 8

4x = x + 3 --- subtract 5 from both sides

3x = 3 --- subtract x from both sides

x = 1 --- divide both sides by 3

Determine the quotient

nexus9112 [7]

Answer:

option 2: $\large \frac{10}{12}$

Step-by-step explanation:

when dividing fractions, you can actually multiply them together by the reciprocal of the second one. (reciprocal is just flipping the fraction)

so, $\frac{2}{3}$ ÷ $\frac{4}{5}$

becomes $\frac{2}{3} * \frac{5}{4}$

to multiply fractions together, just multiply the top and bottom.

2 * 5 = 10

3 * 4 = 12

so the answer would be $\frac{10}{12}$
