5(x + 3) - (9x - 4)

Mathematics
1 answer:
PolarNik [594]4 years ago
5 0

Answer:

\boxed{ \bold{ \huge{ \boxed{  \sf - 4x + 19}}}}

Step-by-step explanation:

\sf{5(x + 3) - (9x - 4)}

Distribute 5 through the parentheses

⇒\sf{5x + 15 - (9x - 4)}

When there is a ( - ) in front of an expression in parentheses, change the sign of each term in the expression. Also, remove the parentheses

⇒\sf{5x + 15 - 9x + 4}

Collect like terms

⇒\sf{5x - 9x + 15 + 4}

⇒\sf{ - 4x + 15 + 4}

Add the numbers : 15 and 4

⇒\sf{ - 4x + 19}

Hope I helped!

Best regards!!

If a b and c are three different numbers which of the following equations has infinitely many solutions
Iteru [2.4K]

Answer: c ax + b = ax+ b

Step-by-step explanation: Seems like a trick question, especially since Answer c has no c in the equation. But once you put in numbers for a,b,and c, there cannot be infinite solutions for x in the first two examples.

Set up two or three equations and test them as proof.

Compare the functions shown below:<br><br> Which function has the greatest maximum y-value?
solmaris [256]
Answer: It's a tie between f(x) and h(x). Both have the same max of y = 3

The highest point shown on the graph of f(x) is at (x,y) = (pi,3). The y value here is y = 3.

For h(x), the max occurs when cosine is at its largest: when cos(x) = 1. 
So,
h(x) = 2*cos(x)+1
turns into
h(x) = 2*1+1
h(x) = 2+1
h(x) = 3
showing that h(x) maxes out at y = 3 as well

--------------------------------

Note: g(x) has all of its y values smaller than 0, so there's no way it can have a max y value larger than y = 3. See the attached image to see what this graph would look like if you plotted the 7 points. A parabola seems to form. Note how point D = (-3, -2) is the highest point for g(x). So the max for g(x) is y = -2

Katarina [22]
If you divide 25 by 12, then you will get 2.083 (3 repeating). If we round that, it will turn to about 3 inches.
