Which of the following is the point and slope of the equation y - 11 = 3(x + 13)?

2 answers:

4 0

The answer is A.

The equation simplifies to y=3x+50.
So, C is already not an option.

Now we just plug in points to see if the point works for the equation.

A-11=3(-13)+50
11=-39+50

11=11

Thus, this point falls on the line of this equation and is a point.

So, the answer is A.

I hope this helps!

Answer:

(-13, 11), 3.

Step-by-step explanation:

This equation is written in the point-slope form of a straight line:

y - y1 = m(x - x1) where m = the slope and (x1, y1) is a point on the line.

So comparing this with the given equation:

y - 11 = 3(x + 13),

we see that y1 = 11 and -x1 = 13 so x1 = -13 and m = 3.

a wildlife photographer spent 5 minutes taking pictures of a bison at a park. when the bison then decided she didn't want her ph

ZanzabumX [31]

The percent of time the photographer spent negotiating with the bison greater than the time he spent taking pictures is 500%

<h3>Percentage</h3>

Time spent taking pictures = 5 minutes
Time spent negotiating = 30 minutes

Percentage of time negotiating greater than taking pictures = (difference in time) / time to take pictures × 100

= (30 - 5) / 5 × 100

= 25/5 × 100

= 5 × 100

= 500%

Ericka decided to compare her observation to the average annual trend, which shows the water rising 1.8 mm/year. Remember, she u

Alex787 [66]

Answer with explanation:

Presume that, initial water level to be, 0 mm, at a time t=0.

And water level is rising at the rate of $1.8 \frac{\text{mm}}{\text{year}}$ .

After 6.2 years level of water will be =1.8 × 6.2

=11.16 mm

→Averge, that is increase in water level after 6.2 years is given by

$=\frac{W_{2}-W_{1}}{t_{2}-t_{1}}\\\\=\frac{11.16-0}{6.2-0}\\\\=\frac{11.16}{6.2}\\\\=1.8 \frac{\text{mm}}{\text{year}}$

→→Rate of Depreciating of water level is given by = Negative of Increase of water level= $-1.8 \frac{\text{mm}}{\text{year}}$

Pls answer fast (√3 + √11)² + (√3 - √11)²

Masja [62]

(√3 + √11)² + (√3 - √11)²

(a+b)² = a² + b² + 2ab
( a - b )² = a² + b² - 2ab

Now ,

(√3 + √11)² + (√3 - √11)²

(3 + 11 + 2√3√11)+ (3 +11 - 2√3√11)

14 + 2√33+ 14 - 2√33

14 + 14 = 28

Hence , The value of (√3 + √11)² + (√3 - √11)² is 28 .

3x-6y=9 x=2y+3 SOMEONE HELP ME SOLVE THIS STEP BY STEP TY

RideAnS [48]

Answer:

0=0

infinitely many solutions

Step-by-step explanation:

plug x=2y+3 as x into 3x-6y=9...so

3(2y+3)-6y=9, which has our x=2y+3 plugged in because that is what x equals

if you solve its

6y+9-6y=9

0y=0

y=0

making it 0=0

you can't go further from this
