Find an equation for these points (-5,5) (4,2)

Mathematics
1 answer:
user100 [1]3 years ago
6 0

Answer:

\large\boxed{y=-\dfrac{1}{3}x+\dfrac{10}{3}}

Step-by-step explanation:

The slope-intercept form of an equation of a line:

y=mx+b

<em>m</em><em> - slope</em>

<em>b</em><em> - y-intercept</em>

The formula of a slope:

m=\dfrac{y_2-y_1}{x_2-x_1}

We have two points (-5, 5) and (4, 2).

substitute:

m=\dfrac{2-5}{4-(-5)}=\dfrac{-3}{9}=-\dfrac{1}{3}

Put the value os a slope and coordinates of the point (4, 2) to the equation of a line:

2=-\dfrac{1}{3}(4)+b

2=-\dfrac{4}{3}+b             <em>add 4/3 to both sides</em>

2\dfrac{4}{3}=b\to b=3\dfrac{1}{3}\to b=\dfrac{10}{3}

Phantasy [73]

Answer:

a) 6 ways

b) 6 ways

Step-by-step explanation:

a) for all of the letters

for the first letter, we have 3 options

for the second, we have 2 options

for the third, we have 1 option

So the number of options will be;

3 * 2 * 1 = 6

b) for the first, we have 3 options, for the second, we have 2 options

so the number of options will be 3 * 2 = 6 options

you have $18 to buy peppers. peppers cost $1.50 each. write and solve an inequality that represents the number of peppers you ca
Nezavi [6.7K]

At most 12 peppers can be bought with $18

Step-by-step explanation:

Given

Total amount for peppers = $18

Cost per pepper = $1.50

Let p be the number of peppers that can be bought from $18 at $1.50 per pepper

So,

1.50p\leq 18

Dividing both sides by 1.50

\frac{1.50p}{1.50}\leq \frac{18}{1.50}\\p\leq 12

Hence,

At most 12 peppers can be bought with $18

Match the amounts and tip or tax rates in the first column to the total costs in the second column.
gogolik [260]

Answer:

1. $132.24

2. $55.89

3. $1336.66

4. $258.19

5. $57.86

Step-by-step explanation:

Simply use this equation.

\frac{InitialValue}{100} = \frac{x}{TaxPercentage}

Substitute in our values, using No.1 as our example.

\frac{123.01}{100}  = \frac{x}{7.5}

Cross multiply

922.575 = x100

Solve for x by dividing by 100.

x = 9.22575

Now add x to the initial value.

9.22575 + 123.01 = 132.23575

Round to the nearest hundredth for the answer.

$132.24
