Answer 1

Answer:

formula

[tex]m = \frac{y2 - y1}{x2 - x1} [/tex]

Step-by-step explanation:

choose two point of A, let k(-2, -3) and l(1, 3)

[tex] m = \frac{ - 3 - 3}{ - 2 - 1} = \frac{ - 6}{ - 3} = \frac{1}{2} [/tex]

choose two point of B, let c(0, 5) and d(5, 0)

[tex]m = \frac{5 - 0}{0 - 5} = \frac{5}{ - 5} = - 1[/tex]

Hence the gradient of A is

[tex] \frac{1}{2} [/tex]

and B is -1

30% of 50

what’s the easiest and fastest way to solve it?

Answers

Step 1: Our output value is 50.

Step 2: We represent the unknown value with $x$.

Step 3: From step 1 above,$50=100\%$.

Step 4: Similarly, $x=30\%$.

Step 5: This results in a pair of simple equations:

$50=100\%(1)$.

$x=30\%(2)$.

Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both
equations have the same unit (%); we have

$\frac{50}{x}=\frac{100\%}{30\%}$

Step 7: Again, the reciprocal of both sides gives

$\frac{x}{50}=\frac{30}{100}$

$\Rightarrow x=15$

Therefore, $30\%$ of $50$ is $15$

Answer:

15

Step-by-step explanation:

change the percent to a decimal

30% to .30

.30 x 50= 15

Not sure if this is what you’re looking for because the question is choppy and some of the letters/words are missing.

Step 2(?) the step with 15 - 3e
When combining 9 = -3e + 6, six would be subtracted from nine equaling three not fifteen.
Correct Steps:
Equation: 9 = -3 (e - 2)

Step 1: 9 = -3e + 6
- 6 - 6
3 = -3e

Step 2: 3 = -3e
/-3 /-3
-1 = e

Answer: -1 = e

Lines s and t are parallel. The slope of line s is −3/2 . What is the slope of line t ?

Find the y intercept of the following line (-2,1) and (1, 2.5)

Answers

Answer:

2

Step-by-step explanation:

(-2 , 1) ; (1, 2.5)

Slope = [tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\[/tex]

         [tex]\frac{2.5-1}{1-[-2]}\\\\= \frac{1.5}{1+2}\\\\=\frac{1.5}{3}\\\\= 0.5[/tex]

m =0.5

y -y1 =m(x -x1)

y - 1 = 0.5(x - [-2])

y - 1 = 0.5(x + 2)

y -1 = 0.5x + 0.5*2

y - 1 =0.5x + 1

  y = 0.5x + 1 + 1

 y = 0.5x + 2

y-intercept = 2

'12 less' means thats u have to subtract 12 from the next number

'7 times a number' means 7 multiplied by a variable like x, y, or z

you put those two together and get 7x - 12

Answer: 7x-12

Step-by-step explanation:

“12 less than” would simply imply “subtract 12 from” the sum of 7 times a number. Let “x” represent the unknown number and multiply it by 7.

Albert O'Malley signs a promissory note for $3,500 for 150 days at 9% exact interest. Find the interest he must pay _____ and the total amount due on the due date _____.

Answers

Answer:

He must pay $129.45 and the total amount due is $3,629.45.

Step-by-step explanation:

I (interest) =P (principal) x R (rate) x T (time)

I=3500x.09x150/365

I=129.45

A (amount due) = P (principal) + I (interest)

A= 3500 + 129.45

How does Ender inspire confidence and loyalty in the soldiers in his army? Why do managers suggest that ignoring all cash flows following the assigned payback period is not a major flaw of the payback method of capital budgeting analysis? Payback is never used in real practice so it makes no difference how academics apply the method in their studies If the cash flows after the required payback period are significant, managers will use their discretion to override the payback rule. All cash flows after the first two years are highly inaccurate so including them lessens the reliability of the resulting decision. All cash flows after the assigned payback period are relatively worthless in todays dollars so ignoring them has no consequence. The results of including the cash flows after the required payback period rarely have any effect on the accept/reject decision.v Nitrogen is necessary for building these two organic molecules:O carbohydrates & lipidscarbohydrates & proteinsnucleic acids & lipidsnucleic acids & proteins A 8-kg load stretches an elastic belt 0.02 m.
