Answer:

Summary. If the equation ends with a false statement (ex: 0=3) then you know that there's no solution. If the equation ends with a true statement (ex: 2=2) then you know that there's infinitely many solutions or all real numbers

Describe in detail two different real-world situations in which you could use the Pythagorean Theorem.
omeli [17]

Answer:

you can use it in architecture and construction

Step-by-step explanation:

say you are building a sloped roof. If you know the height of the roof and the length for it to cover, you can use the Pythagorean Theorem to find the diagonal length of the roof's slope. You can use this information to cut properly sized beams to support the roof, or calculate the area of the roof that you would need to shingle. I hope this helps!

If y varies inversely asx, and y = 33 when x = 7 what is the constant and what is value of y when x=11?
allsm [11]

Answer:

We have that y = 21 when x = 11.

Step-by-step explanation:

We solve this question by proportions, using a rule of three.

Since they vary inversely, we apply the inverse rule of three, that is, with lateral multiplication instead of diagonal.

33 - 7

y - 11

So

11y = 33 -7

y - 11

Dividing both sides by 11

Y = 3 * 7 = 21

We have that y = 21 when x = 11.

A family went on vacation and used 45.3 gallons of gasoline to travel 150 miles. How many total gallons of gasoline will they ne
victus00 [196]

Answer:

d) 105.7\ \text{gallons}

Step-by-step explanation:

150\ \text{miles} requires 45.3\ \text{gallons of fuel}

1\ \text{mile} requires \dfrac{45.3}{150}\ \text{gallons of fuel}

200\ \text{miles} requires 200\times \dfrac{45.3}{150}=60.4\ \text{gallons of fuel}

So, total amount of gasoline required for the trip is 60.4+45.3=105.7\ \text{gallons}.

What is the equation of the line that passes through the point (4,−2) and has a slope of −2?​
AVprozaik [17]

Answer:y=-2x+6

Step-by-step explanation:

You want to find the equation for a line that passes through the point (4,-2) and has a slope of -2.

First of all, remember what the equation of a line is:

y = mx+b

Where:

m is the slope, and

b is the y-intercept

To start, you know what m is; it's just the slope, which you said was -2. So you can right away fill in the equation for a line somewhat to read:

y=-2x+b.

Now, what about b, the y-intercept?

To find b, think about what your (x,y) point means:

(4,-2). When x of the line is 4, y of the line must be -2.

Because you said the line passes through this point, right?

Now, look at our line's equation so far: . b is what we want, the -2 is already set and x and y are just two "free variables" sitting there. We can plug anything we want in for x and y here, but we want the equation for the line that specfically passes through the the point (4,-2).

So, why not plug in for x the number 4 and for y the number -2? This will allow us to solve for b for the particular line that passes through the point you gave!.

(4,-2). y=mx+b or -2=-2 × 4+b, or solving for b: b=-2-(-2)(4). b=6.
