Let f(x)=-2x-7 and g(x)=-4x+6 find (g o f )(-5)

1 answer:

3 0

Easy

(g o f)(-5)=g(f(-5))

first evaluate f(-5), then input the result into g(x)

f(-5)=-2(-5)-7
f(-5)=10-7
f(-5)=3

g(3)=-4(3)+6
g(3)=-12+6
g(3)=-6

(g o f)(-5)=-6

Riley wants to predict a soccer team's number of wins. She considers the number of goals scored by the team's top scorer during

Phoenix [80]

Answer:

b) y=1/3x+5

Step-by-step explanation:

Without the actual scatter plot we would need to deduce from the options provided which would closely model the data. Since the number of goals scored in a game can only be 0 or positives then we can remove options a) and c) since a value of x = 0 would output a negative value to y. That leaves us with options b) and d). Since we know that soccer games vary in the number of goals then we can remove option d) since it represents a steady trend line of 4. Finally, we are left with option b) as the answer.

The amount of money jorge earns for (h) hours of work can be expressed as 100 + 25 (h) which inequality represents the number of

insens350 [35]

Answer:

This means jorge must work for at least 36 hours to earn $1,000. The inequality that represent this expression is h $\geq$ 36

Step-by-step explanation:

Given the amount of money jorge earns for (h) hours of work expressed as 100 + 25 (h). If jorge must work to earn at least $1,000, this means that the lowest amount jorge can earn is $1,000. Jorge cannot earn below but above $1000 i.e he will always earn amount greater than or equal to $1,000.

The statement can be represented using the inequality;

100+25h $\geq$ 1000

To know the number of hours jorge must work to earn at least $1000, we can solve the inequality function for 'h'

Subtarcting 100 from both sides;

100+25h-100 $\geq$ 1000-100

25h $\geq$ 900

dividing both sides by 25

$\frac{25h}{25} \geq \frac{900}{25} \\h\geq 36$

This means jorge must work for at least 36 hours to earn $1,000
