The slope-intercept form of the equation of a line that passes through point (–2, –13) is y = 5x – 3. What is the point-slope fo

rm of the equation for this line?
a y – 13 = 5(x – 2)
b y + 13 = 5(x + 2)
c y – 2 = 5(x – 13)
d y + 2 = 5(x + 13)

The slope is 5 and<span>.
For two lines to be parallel, both of their slopes must be the same. Therefore, our "new" line mus have the slope of 5.
.
Given that we know the slope (5) and a single point (-2, -13) we stuff that into the "point slope" equation:
y - y1 = m(x - x1)
y + 13 = 5(x + 2)</span>

What is the range of the relation y = 3x2 + 4x if the domain is the set (-1,0, 1)?
kicyunya [14]

Answer:

{ - 1, 0, 7 }

Step-by-step explanation:

Substitute the values of x from the domain into the relation to obtain the corresponding values of y , that is the range

x = - 1 : y = 3(- 1)² + 4(- 1) = 3(1) - 4 = 3 - 4 = - 1

x = 0 ; y = 3(0)² + 4(0) = 0 + 0 = 0

x = 1 : y = 3(1)² + 4(1) = 3 + 4 = 7

range is { - 1, 0, 7 }

The modulus of (3 - 4i)^4 is _____. <br><br>5 <br>20 <br>81 <br>625
Ierofanga [76]

Answer:

625

Step-by-step explanation:

The modulus of 3 - 4i is

\sqrt{3^2+(-4)^2} = \sqrt{9+16} = \sqrt{25} = 5, thus

| (3-4i)^{4} |

= 5^{4}

= 625

How many triangles can be constructed with three angles, each measuring 64°?<br><br> 10 POINTS
LUCKY_DIMON [66]

Answer:

<u><em>NONE</em></u>

Step-by-step explanation:

The answer is none. This is because angles in a triangle must add up to 180°, so if you have three angles that are 64° the total would be 192°. I hope this helps!

I'm not sure how to simplify this expression with the exponents rules of multiplication
Vedmedyk [2.9K]
The rule of exponential multiplication is (a^x)*(a^y)=a^(x+y)
using this with your expression, we can do
(10^1)*(10^3)*(10^2)=10^(1+3+2)=10^6
Final answer:
10^6 or 1 million
Hope I helped :)
