What is the slope of the line that passes through points (2,-3) and (5,1)

Ivenika [448]

Find the difference in the y-coordinates: -3 - 1 = -4

Find the difference in the x-coordinates in the same order: 2 - 5 = -3

Divide the difference in y by the difference in x: slope = (-4)/(-3)

Reduce the fraction: slope = 4/3

Simplify your answer

katrin [286]

Answer: $x=4\\y=3$

Step-by-step explanation:

$y=4x-13\\2x+3y=17$

Since our ''y'' is already isolated, you can simply plug ''y'' information into the second equation.

$2x+3y=17\\2x+3(4x-13)=17\\2x+12x-39=17\\14x=17+39\\14x=56\\x=\frac{56}{14} \\x=4$

Now we can use the first equation and replace ''x'' to find ''y''

$y=4x-13\\y=4(4)-13\\y=16-13\\y=3$

To prove that your values are correct, take any of the equations and replace their values.

$y=4x-13\\3=4(4)-13\\3=16-13\\3=3$

Two towns accumulated different amounts of snow. In town 1, the snow depth is increasing by 3 1/2 inches every hour. In town 2 t

san4es73 [151]

Let umber of hours in which snowfalls of the both towns become equal = x

Given that rate at which snow depth is increasing in town 1 =

$3\ \frac{1}{2}=\frac{2*3+1}{2}=\frac{6+1}{2}=\frac{7}{2}$ inches per hour

Then amount of snow fall in x hours in twon 1 = $\frac{7}{2}x$

Given that rate at which snow depth is increasing in town 2 =

$2\ \frac{1}{4}=\frac{2*4+1}{4}=\frac{8+1}{4}=\frac{9}{4}$ inches per hour

Then amount of snow fall in x hours in twon 2 = $\frac{9}{4}x$

when snow fall becomes equal then we get equation:

$\frac{9}{4}x = \frac{7}{2}x$

$\frac{9}{4}x = \frac{14}{4}x$

$0 = \frac{14}{4}x-\frac{9}{4}x$

$0 = \frac{5}{4}x$

$0*\frac{4}{5}=x$

0=x

Hence final answer is 0 hours.

Determine coefficients a and b such that p(x)=x2 ax b satisfies p(1)=5 and p′(1)=11.

Murrr4er [49]

$p(x)=x^2+ax+b$
$p'(x)=2x+a$

Given that $p'(1)=11$ , you have

$p'(1)=2+a=11\implies a=9$

and given that $p(1)=5$ , you have

$p(1)=1+9+b=5\implies b=-5$

So you get

$p(x)=x^2+9x-5$

scoundrel [369]

Answer:

New number of fruits sold = 7 fruits

Step-by-step explanation:

Given:

Total number of fruits = 24

Amount raised = $18

More amount need to earn = $5.25

Find:

New number of fruits sold

Computation:

New number of fruits sold = [24 / 18]5.25

New number of fruits sold = 6.9999

New number of fruits sold = 7 fruits
