Answer: B (2,1)

You know what y is (x-1) so you substitute that for y in the other equation.

3x+ ((4)(x-1))=10

3x+4x-4=10

7x=14

x=2

Then put x=2 into y=x-1

y=2-1

y=1

HURRY!!!!! I NEED HELP!!!!! Find Arc MN A. 20 b.60 c.66 d.120

Ad libitum [116K]

We have been given a circle. We are asked to find the measure of arc MN.

We know that the measure of all arcs in a circle is equal to 360 degrees. SO we can set an equation as:

$\widehat{MN}+\widehat{NO}+\widehat{OL}+\widehat{LM}=360^{\circ}$

Upon substituting our given values, we will get:

$\widehat{MN}+110^{\circ}+130^{\circ}+54^{\circ}=360^{\circ}$

$\widehat{MN}+294^{\circ}=360^{\circ}$

$\widehat{MN}+294^{\circ}-294^{\circ}=360^{\circ}-294^{\circ}$

$\widehat{MN}=66^{\circ}$

Therefore, measure of arc MN is 66 degrees and option 'c' is the correct choice.

Simplify by multiplying 2 (-3x)(-4x +x-7

inna [77]

Hey There.

Hope your well.

2(−3x)(−4x+x−7)

=(2(−3x))(−4x+x+−7)

=(2(−3x))(−4x)+(2(−3x))(x)+(2(−3x))(−7)

=24x^2−6x^2+42x

=18x^2+42x

Hope this helps,
