Mathematics
1 answer:
BabaBlast [244]3 years ago
3 0

Step-by-step explanation:

y =  \frac{1}{2} x + 4

and,

y =  - 2x - 3

represents perpendicular lines.

Two lines are perpendicular when product of their slopes = -1

In, y =½x+4

m1 = ½

In y = -2x -3

m2 = -2

Now, m1× m2 = ½× (-2) = -1

Solve using the elimination method <br>x + 5y = 26 <br>- X+ 7y = 22​
S_A_V [24]

Answer:

x=6\\y=4

Step-by-step explanation:

Elimination method:

x+5y=26

-x+7y=22

Add these equations to eliminate x:

12y=48

Then solve 12y=48 for y:

12y=48

y=48/12

y=4

Write down an original equation:

x+5y=26

Substitute 4 for y in x+5y=26:

x+5(4)=26

x+20=26

x=26-20

x=6

{ x=6 and y=4 }    ⇒ (6,4)

What is % of $2 = $1
ivolga24 [154]

Answer:

50%

Step-by-step explanation:

Let x be equal to the decimal when multiplied by 2 equals 1

2x=1

Divide both sides by 2

\frac{2x}{2} =\frac{1}{2} \\x=0.5

Multiply the decimal by 100 to get a percent

0.5×100=50%

I hope this helps!
