Answer:

Step-by-step explanation:

[tex]f(x)=a(x-h)^2+k[/tex]    vertex form of equation with vertex (h, k)

[tex]\left \big{f(x)=a(x-h)^2+k}\atop \big{f(x)=-(x-2)^2-3}\right\}\implies a=-1\,,\ h=2\,,\ k=-3[/tex]

So vertex of  f(x) = - (x - 2)² - 3 is  (2, -3)

Answer:

The slope is -3/4 or -.75.

Step-by-step explanation:

y1-y2 over x1-x2

Plug it in

9-6 over 1-5.

9-6=3

1-5=-4

Which equals -3/4 or -.75.

Step-by-step explanation:

Answer: 22%

Step-by-step explanation:

Note: in decimal form, this fraction converts to roughly 34.67

=========================================================

Explanation:

Highlight the rows that have x = 0 and x = 3. Cross out or cover the other two rows up.

The two rows that have x = 0 and x = 3 show y = f(x) = 4 and y = 108 respectively.

So we have the two points (0,4) and (3,108). We need to find the slope of the line through these points to find the average rate of change from x = 0 to x = 3.

Turn to the slope formula

m = (y2-y1)/(x2-x1)

m = (108-4)/(3-0)

m = 104/3

We cannot reduce the fraction further.

Using a calculator,

104/3 = 34.67 approximately

Answer:

d = 50h

Step-by-step explanation:

d = distance , h = hours , 50 miles an hour , so 50h

The expression that represents the total distance traveled is 50h .

Distance is the measure of total movement from one place to another , It is a scalar quantity and can be expressed as m and is not dependent upon the direction of the motion.

It is given that

A car travels 50 miles per hour

expression that represents the total distance traveled = ?

Speed = Distance / Time

Given speed = 50 miles/hour

Let h represents the total time

50 = Distance traveled/h

Distance Traveled = 50 h

Therefore the expression that represents the total distance traveled is 50h .

Answer:

a. 15 + 3.55x  = 3.85x b. 50 gallons

Step-by-step explanation:

a. Let x be the number of gallons of gasoline bought in the one month which makes the amount the same in either store.

The amount it costs to buy x gallons of gasoline in the shoppers discount club is 15 + 3.55x and the amount it costs to buy x gallons of gasoline in the gas station is 3.85x.

Since the amount is supposed to be the same after x gallons, we have that

15 + 3.55x  = 3.85x

b. Solving this equation for the gallons of gasoline, x we find that

15 + 3.55x  = 3.85x

collecting like terms, we have

15 = 3.85x - 3.55x

15 = 0.30x

x = 15/0.30

x = 50 gallons

So, they must buy 50 gallons of gasoline to spend the same amount in one month.

Equivalent Ratios

Two ratios are equivalent if they have the same value. To find an equivalent ratio, multiply or divide both quantities by the same number. It is the same process as finding equivalent fractions.

We are given 8 ratios. We'll simplify them to match the blue ratios shown in the image.

[tex]\displaystyle \frac{27}{45}=\frac{27/9}{45/9}=\frac{3}{5}=3:5[/tex]

[tex]\displaystyle \frac{64}{16}=\frac{64/16}{16/16}=\frac{4}{1}=4:1[/tex]

Answer:

After how many moths will Xian and Kai have the same number of stamps?

4 months

How many will each have?

104 stamps

Step-by-step explanation:

Let the number of stamps that they collect be represented by x

Xian and his cousin Kai both collect stamps.

Xian has 56 stamps . Xian's club will send him 12 stamps per month.

= 56 + 12× x

= 56 + 12x

Kai has 72 stamps. Kai's club will send him 8 stamps per month.

= 72 + 8 × x

= 72 + 8x

After how many moths will Xian and Kai have the same number of stamps?

56 + 12x = 72 + 8x

Collect like terms

12x - 8x = 72 - 56

4x = 16

x = 16/4

x = 4

Therefore, after 4 months, Xian and Kai would have the same number of stamps.

How many will each have?

x = 4

56 + 12x = 72 + 8x

56 + 12 × 4 = 72 + 8 × 4

56 + 48 = 72 + 32

104 = 104

Each of them will have 104 stamps.

Answer:

21/16 is 1.3125

Step-by-step explanation:

-1-4-1/2

-1/4-2/4

-1-2 is -3/4

-3/4 / -4/7

-3/4 *-7/4

--21/16 which is +21/16

Answer: 1,125

Step-by-step explanation:

We have to find out what is 25% of 4,500.

Let's subtract by thousands first. We have to subtract 75% of the thousands.

4,000 - 3,000 = 1,000

Now, we have to subtract 75% of 500.

500 - 400 = 100

Now, we have to subtract 75% of 100. We currently have 1,100.

100 - 75 = 25

Add 1,100 and 25.

1,100 + 25 = 1,125

Hope this helps!

Answer:

1,200$

Step-by-step explanation:

500+700 = 1.200$

700 = 100 per day for 7 day vacation

Answer:

$1200

Step-by-step explanation:

So the equation will look like this if d is days and c is cost: c=100d+500 this is it because the $500 is only a one-time fee while $100 is the rate of change so it depends on the number of days you are on vacation. Now since we know how many days we have to go we can just plug it in d: c=100(7)+500

Simplify: c=700+500

Add: c=1200

Answer: $1200
