write an equation in slope intercept form for the line that passes through ( 4, -4) and is parallel to 3 + 4x = 2y - 9​
Kruka [31]

Answer:

y = 2x - 12

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Rearrange 3 + 4x = 2y - 9 into this form

add 9 to both sides

12 + 4x = 2y ( divide all terms by 2 )

6 + 2x = y ← in slope- intercept form

with slope m = 2

• Parallel lines have equal slopes, hence

y = 2x + c ← is the partial equation of the parallel line

To find c substitute (4, - 4) into the partial equation

- 4 =8 + c ⇒ c = - 4 - 8 = - 12

y = 2x - 12 ← equation of parallel line

5x + 2 = 12<br><br> Solve the following equation. Then place the correct number in the box provided.
Ghella [55]

Answer:

x = 2

Step-by-step explanation:

5x + 2 = 12

Subtract 2 from both sides

5x + 2 - 2 = 12 - 2

Simplifying

5x = 10

Divide both sides by 5

5x / 5 = 10/5

Simplifying

x = 2

The space allowed for the mascot on a​ school's Web page is 75 pixels wide by 60 pixels high. Its digital image is 500 pixels wi
anzhelika [568]

Answer:

It will be 60 pixels high and 75 pixels wide

Step-by-step explanation:

\frac{400}{60}=\frac{500}{x}

As

  • The space allowed for the mascot on a​ school's Web page is 75 pixels wide by 60 pixels high
  • Its digital image is 500 pixels wide by 400 pixels high

So, the expression becomes

\frac{400}{60}=\frac{500}{x}

\mathrm{Apply\:fraction\:cross\:multiply:\:if\:}\frac{a}{b}=\frac{c}{d}\mathrm{\:then\:}a\cdot \:d=b\cdot \:c

400x=60\cdot \:500

400x=30000

\mathrm{Divide\:both\:sides\:by\:}400

\frac{400x}{400}=\frac{30000}{400}

\mathrm{Simplify}

x=75

Therefore, it will be 60 pixels high and 75 pixels wide

11.1.30<br> How many three-digit even numbers are possible if the leftmost digit cannot be zero?
Ann [662]

The total number of 3 digit even numbers is 450

Step-by-step explanation:

Step 1 :

We need to determine the  number of 3 digit numbers which is even and the leftmost digit is not zero .

The  3 digits with left most digit not equal to zero starts from 100 and goes up to 998

If we consider only the even 3 digit numbers in this interval, this would form an arithmetic progression with the first number a = 100 and the common difference d = 2.

Step 2:

The last number l  in this series is 998 .

So we have

a = 100

l = 998

d = 2

The nth term in the arithmetic progression is given by a + (n-1) d

so substituting the above values we get

100 + (n-1) 2 = 998

2n = 900  => n = 450

Step 3 :

Answer :

The total number of 3 digit even numbers is 450
