Step-by-step explanation:

Two lines are perpendicular, and neither line is horizontal. Which of the following is not necessarily true of the lines?A.
The slopes of the two lines are opposite reciprocals.
B.
One line must have a positive slope.
C.
The y-intercepts are the same.
D.
One line must have a negative slope.

Answers

I think the correct answer from the choices listed above is option C. Two lines are perpendicular, and neither line is horizontal so it must be that the slopes of the lines are opposite reciprocals, one slope is positive and the other has a negative slope. Having different slopes so they should intersect the y-axis at different values.

(3x²y³)(-5xy^{4}z)When multiplying the variables, do you multiply the x by the x next to the y^{4}z, and the y with the y^{4}? I asked my teacher this question for a similar problem and he said not to. When I asked my dad for help with this problem, he said that you do and the answer is -15x^{3}y^{7}z. Which method is correct?

Answers

remember
x^m=x times itself m times

REMEMBER THAT MULCTIPLICATION IS COMMUTATIVE
a(bc)=(ab)c


so basically
(abc)(3ac)=a*b*c*3*a*c=a*a*c*c*b*3=3a^2bc^2
group and regroup and move around


so in your problem
(3x^2y^3)(-5xy^4z)=
(3)(x^2)(y^3)(-5)(x)(y^4)(z)=
(3)(-5)(x^2)(x)(y^3)(y^4)(z)=
(-15)(x^3)(y^7)(z)=
-15x^3y^7z

For what values of x is the expression below defined?o A. 3 x s 1O B. -3 x 1O C. 3 x S-1

Answers

remember
you when you put a negative inside the square root signs, it is complex and undifined

find which values you can use

x+3
what values make it 0? (the boundary between negative and possivie)
x+3=0
x=-3
has to be more than or equal to 0 (because √0=0)
x>-3

2nd one
1-x=0
1-x>0
add x both sides
1>x

so
x>-3 and 1>x
1>x and x>-3
1>x>-3
-3<x<1

Answer this: Solve for X
IMAGE below!

Answers

Answer:

x =22.5

Step-by-step explanation:

x+3x = 90

x and 3x are complementary so they add to 90 degrees

Combine like terms

4x =90

Divide each side by 4

4x/4 = 90/4

x =22.5

answer: x = 22.5

explanation:

as the 3x and x are on a straight line with the angle of 90° we know that

3x +x = 90

4x = 90

x = 22.5
