Nine less than three times a number is greater than forty

pentagon [3]

Start with an equation.
Nine less... so -9
3 times a number = 3x
Greater than 40 is >40

So put together is 3x-9>40
When solving I imaging the greater than sign as an equal sign. Less confusing.
3x-9=40
3x=49
x>49/3

Write the compound statement "I'll exercise if I don't eat too much" in symbols.Let p = "I eat too much"q = "I'll exercise"A. ~p

butalik [34]

We can begin by rewriting the sentence in a more convenient way:

"If I don't eat too much, I'll exercise."

The phrase speaks about an action (exercise) that is going to be done provided a condition is fulfilled (don't eat too much) This is a conditional.

p = I eat too much

~p = I don't eat too much.

Then, if ~p happens, then q will happen

We can write this as

~p->q

With this, the correct answer is option D.

Find the equation of a line perpendicular to y - 12 = 2x – 8 that passes through the point (2, 3). (answer in slope-intercept fo

Alla [95]

Answer:

$\displaystyle y=-\frac{1}{2}x+4$

Step-by-step explanation:

<u>Equation of a Line</u>

We can find the equation of a line by using two sets of data. It can be a pair of ordered pairs, or the slope and a point, or the slope and the y-intercept, or many other combinations of appropriate data.

We are given a line

$y - 12 = 2x -8$
