This is a true or false answer please help me**

Nitella [24]

Answer:

5False

6 true

7 true

Step-by-step explanation:

5 Complementary angles add to 90 degrees not 180 degrees

6 40+50 = 90 so they are complementary

7 Supplementary angles add to 180

145+x = 180

Subtract 145 from each side

145-145 +x = 180-145

x = 35

A line has an c intercept of 3 and a y intercept of negative 6. What is the slope intercept form of it’s equation

Schach [20]

Answer:

y = 2x - 6

Step-by-step explanation:

Slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept.

The y-intercept is already given and is -6.

By c intercept, I am assuming you meant x-intercept. With an x-intercept of 3, the point is (3,0). With a y-intercept of -6, the point is (0,-6).

Use the two points to find the slope using the following equation.

$m=\frac{y_{2}-y_{1} }{x_{2}- x_{1} }$

Plug the points into their respective positions and solve.

$m=\frac{-6-0}{0-3}\\ m=\frac{-6}{-3} \\m=2$

The slope is 2.

Your equation is y = 2x - 6.

Which property is used in the problem below? 2(x+4)=2x+8 the associative property the commutative property the distributive prop

Serga [27]

The answer is C) The Distributive property.
2(x+4) got turned into 2x+8.

The distributive property does this:
2 times x plus 2 times 4.

2 times x = 2x
2 times 4 = 8.

So the answer is 2x+8.

C) Distributive property is right.

What is the range of possible sizes for side x

Xelga [282]

Answer:

0.5 < x < 16.5

Step-by-step explanation:

For a triangle (by the triangular inequality theorem), we know that the sum of any two sides must be larger than the other side.

When we have a triangle and we know two sides, let's define the measures of these sides as S1 and S2. (such that S2 > S1)

By the first property, we will have that S1 + S2 > S3

Where S3 is the third side, the one that we do not know.

But there is also a lower restriction, given by:

S2 - S1 < S3 < S1 + S2

This is because we also must have:

S1 + S3 > S2

and

S2 + S3 > S1

We can rewrite both of these to get:

S2 - S1 < S3

S1 - S2 < S3

Because S2 > S1, the first inequality is more restrictive, so we need to use that one.

Then we get the inequality:

S2 - S1 < S3 < S1 + S2

Ok, in this case, the shorter side is 8.0 then:

S1 = 8.0

And the longer side is 8.5, then:

S2 = 8.5

And the third side is x, S3 = x

Replacing those in our inequality, we get:

8.5 - 8.0 < x < 8.5 + 8.0

0.5 < x < 16.5

This is the range of possible sizes for side x.
