Answer:

B

Step-by-step explanation:

So from the first graphs equation is

2x-y=-1

therefore if we made y the subject of the formula, the equation would be

2x+1=y , this is also the same as y=2x+1

from this, the equation is clearly in the form y=mx+c so we can get the gradient

The gradient of graph one would be 2

The perpendicular gradient would be the negative reciprocal of graph one's gradient which would be -1/2

Now we look at our options and see which one has the gradient as -1/2

Answer:

True, based on the <em>Transitive Property of Equality</em>.

Step-by-step explanation:

Note that the <em>Transitive Property of Equality </em>states that "If a = b, & b = c, then a = c.

In this case it is the same.

∠1 ≅ ∠2 (because both are complementary), ∠1 ≅ ∠3 (again, both are complementary), then based on the Transitive Property, ∠2 ≅ ∠3, making all of them complementary angles

Which of the following shows the solution to the inequality
otez555 [7]

Answer:

I got x = 1

Step-by-step explanation:

First to isolate the variable you add 3 to both sides which will give you 1/2x is less than or equal to 2. Then divide both sides by 1/2 and you will get x = 1. To check the answer I just did:    

1/2(1) -3 \leq -1\\1/2 -3\leq -1\\-2.5\leq -1

And since -2.5 is less than -1 this statement is true. x does in fact equal 1
