Answer 2

Answer:

x=-2

Step-by-step explanation:

R=1

Y=1

So the equation is

What is the slope of a line that is perpendicular to a line that has a slope of -7

Please help ya girl out :))

Answers

C. 1/7
The slope of a perpendicular line will be the opposite of the first slope given. So since the first slope is -7 then we make the negative positive and flip the numerator and denominator. So -7/1 will be 1/7

6t - 9u = 10
2t + 3u = 4

solve by elimination please

Answers

Answer:

I got u= 1/9 and t=11/6

Step-by-step explanation:

hope this helps

The solution to the equation is t= 11/6 and u= 1/9.

What is Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side. It demonstrates the equality of the relationship between the expressions printed on the left and right sides. Every mathematical equation begins with L.H.S = R.H.S.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given equation:

6t - 9u = 10........(1)

2t + 3u = 4.........(2)

Multiply equation(2) with 3 we get

6t+ 9u = 12...(3)

Now, subtract (3)- (2)

18u= 2

u= 2/18

u= 1/9

and, 6t - 9(1/9)= 10

6t - 1= 10

6t= 11

t= 11/6

Answer:

5b +3r -12k +5-13k +2

Step-by-step explanation:

It looks like you want to simplify the sums.

1. (3r -4) -(-5b -3) = 3r -4 +5b +3 = 5b +3r +(-4+3)

= 5b +3r -1

2. (-4k -1) -(-6k -6) = -4k -1 +6k +6 = (-4+6)k +(-1+6)

= 2k +5

3. (-6k +7) -(7k +5) = -6k +7 -7k -5 = (-6-7)k +(7-5)

= -13k +2

Can anyone help me with this algebra problem ?

Answers

Answer:

Step-by-step explanation:

Answer:

y=mx+b is the form in which these equations are. B represents the y intercept and M is the slope

currently to find slope we need to get y alone on the left side of the equation for all the answers:

A.y-4=3(x-2) -----> y-4=3x-6 (i also distributed) ----> y=3x-2

B. y+4=-3(x+2)----> y+4=-3x-6 -------> y=-3x-10

C. y-2=-3(x-4) --------> y-2=-3x+12 ------> y=-3x+14

D. y-4= -3( x-2) --------> y-4= -3x+6 ---------> y=-3x+10

All of these equations except A have a slope of -3 so A is already out and to find which one is valid we need to plug in the point (2, 4) for each of the equations

B. 4=-3(2)-10 ------> 4=-6-10----> 4=-16- not valid

C. 4 =-3(2)+14 -----> 4=-6+14------>4=8 not valid

D. 4=-3(2)+10 ----->4=-6+10 ------> 4=4 - Valid

Only D is correct
