4 0

Answer:

1

Step-by-step explanation:

We can use the slope formula

m = ( y2-y1)/(x2-x1)

    = ( 4-2)/(1 - -1)

    = (4-2)/(1+1)

      = 2/2

    = 1

What is m∠C?<br><br><br><br> Enter your answer in the box.<br><br> m∠C= °
serious [3.7K]

Answer:

m∠C = 60°

Step-by-step explanation:

First, let's start with the fact that all angles in a triangle add up to 180°. That means that:

x+3x+2x=180°

We can simplify it into:

6x=180°

To figure out x, we need to divide 180 by 6.

That means each x is 30°

m∠C = 2x

m∠C = 60°

Two linear equations are given below.
gladu [14]

Answer: You can't answer this, but here are some guidelines

Step-by-step explanation:

I would love to answer this question (coming from someone who has already completed algebra keystones) but I need to know what the linear equations are before I can. If the functions are reciprocals of one another (the slope is the opposite and the fraction is switched) it is a perpendicular line which means one solution.  If the slope is the same but the intercept is different (using y=mx+b) so if b is different but m is the same they are parallel and there is no solution. If they are the same line (same equation) there is infinite solutions. If this doesn't help I would suggest finding graph paper and trying it out and seeing the intersection points.

During the first 50 minutes of flight, the Concorde climbs from ground level to an altitude of about 52,000 ft. What is the conc
horsena [70]

Let

x--------> the time in minutes

y-------> an altitude in feet

we know that

For x=0 min  y=0 ft

For x=50 min y=52,000 ft

so

the rate of change is equal to calculate the slope of the linear equation

\frac{52,000-0}{50-0}=\frac{52,000}{50}=1,040\frac{ft}{min}

Round to the nearest hundred-------->1,000\frac{ft}{min}

therefore

<u>the answer is</u>

1,000\frac{ft}{min}
