For this case we have the following expression:

4 (3a + 7) +3 (2a + 5)

We must evaluate the expression for the following value:

a = 5

We have then:

4 (3 (5) +7) +3 (2 (5) +5)

Then, rewriting the expression we have:

4 (15 + 7) +3 (10 + 5)\\4 (22) +3 (15)\\88 + 45\\133

Answer:

The expression for a = 5 is given by:

4 (3a + 7) +3 (2a + 5) = 133

Q# ..7 match the equation with its graph -4x - 2y =8
prisoha [69]

If you divide by 8, you can put the equation into intercept form. That form is ...

... x/a + y/b = 1

where <em>a</em> and <em>b</em> are the x- and y-intercepts, respectively.

Here, your equation would be

... x/(-2) + y/(-4) = 0

The graph with those intercepts is not shown with your problem statement here. See the attachment for the graph.

What’s the Value for k?
xeze [42]

Answer:

Step-by-step explanation:

The sum of the angles on a straight line is 180 degrees. Therefore,

Angle XYZ + angle MYZ = 180

Angle XYZ + 115 = 180

Angle XYZ = 180 - 115 = 65 degrees

The sum of the angles in a triangle is 180 degrees. It means that

Angle XZY + angle YXZ + angle MYZ = 180

Therefore,

4k + 5 + 6k + 10 + 65 = 180

4k + 6k + 5 + 10 + 65 = 180

10k + 80 = 180

10k = 180 - 80 = 100

Dividing the left hand side and the right hand side of the equation by 10, it becomes

10k/10 = 100/10

k = 10
