Devon babysits x hours a week after school for 5$ an hour, and also has a job as a cashier y hours a week for $10 an hour. He wa
Papessa [141]

Answer:

The inequality expression are  5x + 10y\geq\$70 \ and \ x + y \leq 10 hours

Step-by-step explanation:

Given:

Number of hours for babysitting for a week = x \ hours

Charge for baby sitting = 5$ an hour

Money earned for babysitting in x hours = 5x

Number of hours for cashier for a week = y \ hours

Charge for Cashier = $10 an hour

Money earned for Cashier in y hours = 10y

He wants to earn at least 70$.

Hence the expression becomes.

5x + 10y \geq 70 \$

Also,

He can’t work any more than 10 hours a week

Hence the expression becomes.

x + y < 10 \ hours

Inequality equation for the given statements are:

The inequality expression are  5x + 10y\geq\$70 \ and \ x + y \leq 10 hours

Find the equation of the line through point (8,−9) ( 8 , − 9 ) and perpendicular to 3+8=4 3 x + 8 y = 4 .
Leno4ka [110]

The equation of the line will be 3y + 8x = 165.

<h3>What is an equation?</h3>

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

Given that:-

  • Find the equation of the line through point (8,−9) ( 8, − 9 ) and perpendicular to 3 x + 8 y = 4.

The given equation of the line is:-

3 x + 8 y = 4.

The slope of this line will be:-

3 x + 8 y = 4.

8y = -3x + 4

y = -3 /8x + ( 1 / 2)

y = mx + c

m = -3 / 8

Since the line is perpendicular to the other line 3x +8y = 4 so the slope will be inverse and negative for the line.

So the slope of the line will be -8 / 3

The equation of the line passing through the point will be given as:-

y - y 1 = m ( x- x1)

y - (-9) = ( -8 / 3) ( x - 8)

Y + 9 = ( -8 / 3 ) ( x -8 )

3 y = -8x + 165

3y + 8x = 165

Therefore the equation of the line will be 3y + 8x = 165.
