Simplify the expression -3(4x +5) - 2(-5x +8)

Mathematics
1 answer:
STALIN [3.7K]3 years ago
6 0

Answer:

x=-31/2

Step-by-step explanation:

Let's equate the equation to zero

-3(4x+5)-2(-5x+8)=0

-12x-15+10x-16=0

Collect like terms

-12x+10x-15-16=0

-2x-31=0

Add 31 to both sides

-2x=31

Divide both sides by-2

x=-31/2

Hi!

To solve this, we must make an equation in y = mx + b form, where m is the slope and b is the y-intercept.

Since we are looking at a graph with points, it saves us a TON of work, and all we have to do is simply look at the graph. We only need to find m and b, that's it!

M is the slope, and the slope can be represented by the change between points on a line, also known as <em>rise/run. </em>

If we start at point (-4, -1), and go to point (-2, 0), we can see that it goes up 1 and right 2, which would be represented as 1/2.

B is the y-intercept, and that is simply the point that is on the y-axis, which is the point (0, 1), so our number would be 1.

Therefore, plugging these numbers into the equation, our equation is y = <em>1/2</em>x + <em>1</em>

<em></em>

Hope this helps! :D

blondinia [14]

Answer:

d)  x  = 72°

Step-by-step explanation:

Corresponding Angles:   The pair of angles formed on the same side of traversal which crosses two parallel lines is called a pair of corresponding angles.

These angles are EQUAL to each other.

Now, here in the given figure:

The two below lines are parallel to each other.

Also, the line crossing it on the right side forms a traversal.

So angle x and angle with 72 degrees form a pair of Corresponding Angles.

⇒ x  = 72°

Hence the measure of angle x  = 72°
