For two functions, a(x) and b(x), a statement is made that a(x) = b(x) at x = 2. What is definitely true about x = 2?
serious [3.7K]

Answer:

The answer is Both a(x) and b(x) have the same output value at x = 2.

Step-by-step explanation:

The answer is Both a(x) and b(x) have the same output value at x = 2. Because when a(x)=b(x) the lines intersect at that point lines intersect they have a point in common. Also, a(x)=b(x) means that the outcomes are the same

Given the function f(x)=2(3x+7)−4(x−2), what would be the value of input, x, if f(x)=18?
Hatshy [7]

Answer: x=-2

Step-by-step explanation:

Given

f(x)=2(3x+7)-4(x-2)

f(x)=18

Use substitution method

2(3x+7)-4(x-2)=18

Expand parenthesis

6x+14-4x+8=18

Combine like terms

2x+22=18

Subtract 22 on both sides

2x+22-22=18-22

2x=-4

Divide 2 on both sides

2x/2=-4/2

x=-2

Hope this helps!! :)

A Chef prepares and evenly divides s ounces of beef stock into 3 smaller pans. The chef uses 8 ounces of beef stock form one of
saw5 [17]

Answer:

Thus, the equation hat correctly represents the number of ounces of beef stock, s, that the chef initially prepares.

⇒ \frac{s}{3}-8=34

The total number of ounces of beef stock = 126

Step-by-step explanation:

Given:

Total ounces of beef stock = s

The chef divided the beef stock  evenly into 3 smaller pans.

The chef then uses 8 ounces from one of the smaller pans.

Ounces of beef stock left in the smaller pan = 34

Solution:

Total ounces of beef stock = s

Ounces of beef stock in each smaller pan = \frac{s}{3}

Ounces of beef stock used by the chef from the smaller pan = 8.

The ounces of beef stock left in the smaller pan will be given as:

⇒ \frac{s}{3}-8

Ounces of beef stock remaining in smaller pan = 34

Thus, the equation hat correctly represents the number of ounces of beef stock, s, that the chef initially prepares.

⇒ \frac{s}{3}-8=34

Solving for s.

Adding 8 both sides.

⇒ \frac{s}{3}-8+8=34+8

⇒ \frac{s}{3}=42

Multiplying both sides by 3.

⇒ 3\times \frac{s}{3}=42(3)

∴ s=126

Thus, total number of ounces of beef stock = 126
