Write the equation of a line in slope-intercept and standard form.Given 1 point and a slope

Answers

Answer:

The equation of line is as follows:

Slope-intercept form: [tex]y = 7x-5[/tex]

Standard Form: [tex]-7x+y = -5[/tex]

Step-by-step explanation:

Given that

Slope of line: 7

Point : (1,2)

Slope-intercept form of equation of line is given by:

[tex]y = mx+b[/tex]

Here m is the slope and b is y-intercept.

Putting the value of slope

[tex]y = 7x+b[/tex]

To find the value of b, we have to put the point in the equation

[tex]2 = 7(1) +b\\2 = 7+b\\2-7 = b\\b = -5[/tex]

So the equation will be:

[tex]y=7x-5[/tex]

The standard form of equation of line is:

[tex]Ax+By = C[/tex]

To convert the equation in standard form, subtracting 7x from both sides

[tex]y-7x = 7x-5-7x\\-7x+y = -5[/tex]

Hence, the equation of line is as follows:

Slope-intercept form: [tex]y = 7x-5[/tex]

Standard Form: [tex]-7x+y = -5[/tex]

The equation of a line in slope-intercept and standard form through (1, 2), slope = 7 is  7x - y = 5.

To find the equation of a line in slope-intercept and standard form.

First, we can write the equation in point-slope form. The point-slope formula states:

(y − y₁) = m (x − x₁)

Where m is the slope and

(x1, y1) is a point the line passes through.

Substituting the values from the problem gives:

(y − 2) = 7(x − 1)

Now, we need to convert to standard form.

The standard form of a linear equation is:

Ax + By = C

where, if at all possible,

A, B, and C are integers, and A is non-negative, and, A, B, and C have no common factors other than 1

We convert as follows:

y − 2 = (7 × x) − (7 × 1)

y − 2 = 7x − 7

−7x + y − 2  = − 7

Adding 2 in both side.

−7x + y − 2 + 2 = − 7 +2

-7x + y = -5

7x - y = 5

Therefore,  the equation of a line in slope-intercept and standard form is 7x - y = 5.

The local newspaper has letters to the editor from 50 people. If this number represents ​%8 of all of the​ newspaper's readers, how many readers does the newspaper​ have?

Answers

Answer:

625 is the correct answer :)

Step-by-step explanation:

hope this help  

The newspaper has 625 readers.

What is a percentage?

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

Example:

Required percentage value = a

total value = b

Percentage = a/b x 100

Example:

50% = 50/100 = 1/2

25% = 25/100 = 1/4

20% = 20/100 = 1/5

10% = 10/100 = 1/10

We have,

8% = 50 people

Multiply 100/8 on both sides,

100% = 100/8 x 50 people

100% = 625 people

Thus,

There are 625 readers.

Step-by-step explanation:

Here's the equation and the workthru of my logic:

-5 (p + 3/5) = -4

Divide both sides by -5 to remove the -5 from the left side of the equation,

p + 3/5 = -4/5,

Subtract 3/5 from both sides to solve for p,

p = -4/5-3/5

p = -7/5

Solution is -7/5

In a two-digit number, the tens digit is 5 less than the units digit. The number itself is five more than three times the sum of its digits. What is the number?

Answers

38. Mark Brainliest Please

The tens digit is 3 and the unit digit is 8. So, the number is 38.

Important information:

The tens digit is 5 less than the unit digit.The number itself is five more than three times the sum of its digits. System of equations:

Let x be the tens digit and y be the unit digit.

The tens digit is 5 less than the unit digit.

[tex]x=y-5[/tex]           ...(i)

The number itself is five more than three times the sum of its digits.

[tex]10x+y=3(x+y)+5[/tex]

[tex]10x+y-3x-3y=5[/tex]

[tex]7x-2y=5[/tex]           ...(ii)

Using (i) and (ii), we get

[tex]7(y-5)-2y=5[/tex]

[tex]7y-35-2y=5[/tex]

[tex]5y=40[/tex]

[tex]y=8[/tex]

Substitute this value in (i).

[tex]x=8-5[/tex]

[tex]x=3[/tex]

Therefore, the number is 38.
