5 0

The answer is: x=5

Distribute first, and you get (4x+44=64). Subtract -44 and move it over to 64. (4x=20). Divide it and the answer is 5

Use slopes to determine if the lines y= -x/3- 9 and 6x – 2y = -5 are perpendicular.
WARRIOR [948]

Answer:

They are perpendicular.

Step-by-step explanation:

When we convert the equation 6x-2y=-5 into y=mx+b form, it changes into y=3x-5/2. Since we know that perpendicular slopes are opposite reciprocal, the opposite reciprocal of -x/3 is 3. So, we know that these 2 slopes are perpendicular.

Find the distance between 4 2/3 and −5 1/3
svetoff [14.1K]

Answer:

The distance between these two is 10.

Step-by-step explanation:

In order to find this, we simply need to subtract the values from one another. If the value is then negative, we take the absolute value to find the distance.

4 2/3 - -5 1/3

4 2/3 + 5 1/3

10

Evaluate <br> a<br> +<br> 4<br> a+4a, plus, 4 when <br> a<br> =<br> 7<br> a=7a, equals, 7.
Scilla [17]

<em>When evaluating a=7 then we get that the expression is 11</em>

<h2>Explanation:</h2>

As I understand the expression is the following:

a+4

Let's call, that expression as E

So we are asked to find the value of the expression when a=7. In other words, we need to substitute a=7, so:

E(7)=(7)+4 \\ \\ E(7)=11

So <em>when evaluating a=7 then we get that the expression is 11</em>

The figure below is Circle E. Line CF is tangent at point C.
slava [35]

Answer:

Part 1) m

Part 2) m

Part 3) m

Step-by-step explanation:

Part 1) Find the measure of angle ECF

we know that

CF is tangent at point C

so

the radius EC is perpendicular to the tangent CF

therefore

m

Part 2) Find the measure of angle AKB

we know that

The measure of the interior angle is the semi-sum of the arcs comprising it and its opposite

m

substitute the values

m

Part 3) Find the measure of angle ACF

we know that

The inscribed angle is half that of the arc it comprises

m

substitute the values

m
