Equation a: 3x y = 6 equation b: 6x - 2y = 4 equation c: y = 3x - 2 equation d: y = 1/3x 7 which two lines are perpendicular?

1 answer:

7 0

Perpendicular have slopes that multil to -1
for
ax+by=c
slope=-a/b

and

y=mx+b
m=slope

equations find slope
A. -3/1=-3
B. -6/-2=3
C. 3
D. 1/3

1/3 times -3=-1

A and D

C is the answer

SOMEONE PLSLPLSSLSLS HELP ITS JUST 3 QUESTIONS BRO PLEASE ITS SO CONFUSING ILL BRAINLIST.

Vinil7 [7]

Step-by-step explanation:

a) Perimeter is equal to 2w + 2L

2(3x + 4) + 2(x + 3)

6x + 8 + 2x + 6

8x + 14

b) Put 5 in x's place

8×5 + 14

40 + 14

c) Area = (3x + 4) * (x + 3)

Put 4 in x's place

(3×4 + 4) * (4 + 3)

12 + 4 * 7

16 * 7

Mx-ymx-y

m=5m=5
x=3x=3
y=8y=8
So... They all have to be 0 otherwise they are false so...

Hope this helps :)

Answer:

<h3>The reason which is incorrect is in Step 2 and reason 2</h3>

Step-by-step explanation:

Given that Logan's equation is $\frac{3}{2}\times (x-10)=50$

<h3>To simplify and find the which reason is incorrect :</h3>

Logan's solution and reasoning for solving an equation are shown below:

Step1 $\frac{3}{2}\times (x-10)=50$

Reason 1: Given

Step2 $\frac{3}{2}\times x-10+10=50+10$

Reason 2: Addition Property of Equality

Step3 $\frac{3}{2}\times x=60$

Reason 3: Simplify

Step4 $\frac{3}{2}\times x \times (\frac{2}{3})=60\times (\frac{2}{3})$

Reason 4: Division Property of Equality

Step5 $x=40$

Reason 5: Simplify

<h3>The reason which is incorrect is in Step 2 and reason 2</h3><h3>The corrected steps are</h3>

Step1 $\frac{3}{2}\times (x-10)=50$

Reason 1: Given

Step2 $\frac{3}{2}\times (x)-\frac{3}{2}\times (10)=50$

Reason 2: Distributive property

Step3 $\frac{3}{2}\times x-15=60$

Reason 3: Simplify

Step4 $\frac{3}{2}\times x-15+15=50+15$

Reason 4: Addition Property of Equality

Step5 $\frac{3}{2}\times x=65$

Reason 5: Simplify

Step6 $\frac{3}{2}\times x \times (\frac{2}{3})=65\times (\frac{2}{3})$

Reason 6: Division Property of Equality

Step7 $x=\frac{130}{3}$

Reason 7: Simplify
