Answer:

Step-by-step explanation:

You can get the slope of a line with the following equation y2 - y1 / x2 - x1

Thus the unsimplified answer is -4/12, but this needs to be simplified. By finding the least common denominator, you can make slopes easier to use. Using this method, the answer is -1/3

DochEvi [55]

Answer:The measure of angle RST is 120\°

Step-by-step explanation:

see the attached figure to better understand the problem

we know that

m<RST=(6x+12)\° -----> equation A

m<RST=78\°+(3x-12)\° -----> equation B

equate equation A and equation B

(6x+12)\°=78\°+(3x-12)\°

Answer:

300 miles.

Step-by-step explanation:

Distance = Rate * Time

We know the rate, 80 miles per hour.

We know the time, 3.75 hours.

As these use the same time unit, hours, we don't need to change any values.

We can just put these values into the formula:

$d=r*t$

$d=80*3.75=300$

Answer: 300 miles.

What is the solution set of the quadratic inequality f(x) greater than or equal to 0

stellarik [79]

ANSWER

{ $x | x \in \: R$ }

EXPLANATION

From the graph, the given quadratic inequality is

${(x + 3)}^{2} \geqslant 0$

We can see that the corresponding quadratic function is a perfect square.

Since the graph opens upwards and it is always above the x-axis, any real number you plug into the inequality, the result is greater than or equal to zero.

Hence the solution set is

{ $x | x \in \: R$ }

The correct answer is A
