Which of the following expressions represents "The product of 9 and a number, diminished by 7"?a)9n - 7

b)9n · 7

c)9(n + 7)

Answers

Answer:

a) 9n-7

Step-by-step explanation:

Let the unknown number be represented by placeholder n.

Then the product of 9 and the number is represented by 9*n or 9n.

This value diminished by 7 corresponds to 9n - 7.

So the expression representing the required overall construct mathematically is given by 9n-7

Option b, 9n * 7 represents the product of 9n and 7.

Option c, 9(n+7) represents the product of 9 and (n incremented by 7).
a)9n - 7

B show product of 9 and a number multiplied by a number
C shows the product of number plus 7 and 9

If h(r) = 23r − 6, what is the value of h(-9)? Question 5 options: a) 0 b) 12 c) −623 d) -12

Answers

Answer:

-213

not in d option though check d question

Step-by-step explanation:

h(r) = 23r − 6

h(-9) = 23(-9) - 6

= -207 - 6

= -213

Answer:

-213

Step-by-step explanation:

If h(r) = 23r − 6, then, if we choose r = 2 as an example (only), then:

If h(2) = 23(2) − 6 = 46 - 6 = 40

Using the same approach, we substitute -9 for r, obtaining:

If h(-9) = 23(-9) − 6 = -207 - 6 = -213

A car uses one gallon of gasoline for every 20 miles it travels. If a gallon of gasoline costs $3.98, how much will the gas cost, to the nearest dollar, to travel 180 miles?

Answers

$x/180mi=$3.98/20mi.
180/20=9
so 3.98(9)=$ for 180 miles.  
3.98(9)=$35.82
