Answer:

.

Step-by-step explanation: The first answer is c. 7+3w, because the puppy already weighs 7 ounces. Since the puppy didn't end up losing those pounds, then you would add instead of subtract. Since the puppy gains 3 ounces a week, you would multiply the 3 ounces by the number of weeks that pass by. So, if one week passes, the puppy gains three ounces. Add that to the original 7 ounces, then after one week, the puppy weighs 10 ounces.

The second answer would be a. 22 ounces, because if you use the previous formula (x=7+3w), then you would plug 5 in for w. This would give you 7+3(5). 3x5=15 and 15+7=22. therefore, x=22 ounces.

Answer:

7)c, 8)a

Step-by-step explanation:

since it is originally 7 oz, and grows 3 ounces a week, it would be 7+3w.

Substitutions would be 7+3(5) = 7+15 = 22 oz

The equation y=2(x-1)^2-5y=2(x−1)

marin [14]

Answer:

(b) It is symmetrical about $x = 1$

Step-by-step explanation:

Given

$y = 2(x - 1)^2 - 5$

See attachment for options

Required

True statement about the graph

First, we check the line of symmetric

$y = 2(x - 1)^2 - 5$

Expand

$y = 2(x^2 - 2x + 1) - 5$

Open bracket

$y = 2x^2 - 4x + 2 - 5$

$y = 2x^2 - 4x -3$

A quadratic equation $y = ax^2 + bx + c$ has the following line of symmetry

$x = -\frac{b}{2a}$

By comparison, the equation becomes:

$x = -\frac{-4}{2*2}$

$x = \frac{4}{4}$

$x = 1$

Hence, the line of symmetry is at: $x = 1$

(b) is true.

Megan's commute to work includes an 8-mile drive and a 21-mile train ride. This expression can be used to find the total time it

ArbitrLikvidat [17]

Answer:

(8 / x) + (21 / y)

Step-by-step explanation:

Given that:

Average driving speed = x mph

Miles driven to work = 8 mile

Miles by train to work = 21 miles

Average train speed = y

Total time taken to get to work. :

Recall : time taken = distance / speed

Hence,

Time taken =) total distance / average driving speed)

Total time taken = (8 / x) + (21 / y) hours

Total time taken = (8 / x) + (21 / y) hours
