Answer:
7
Step-by-step explanation:
We have that x1=−1, y1=5, x2=3, y2=7.
Plug the given values into the formula for a slope: m=7−(5)3−(−1)=12.
Now, the y-intercept is b=y1−mx1 (or b=y2−mx2, the result is the same).
b=5−(12)(−1)=112
Finally, the equation of the line can be written in the form y=b+mx:
y=112+x2

Step-by-step explanation:
219 divided by 2 equals 109.5, so you basically just round to the nearest whole number. You should get 110, thus, your answer. Of course, you could just leave it as 109.5, but if you want it estimated, or simplified, the information above should help.

Which statements apply to the ratio of rice and water? Choose two options.
The amount of rice is the dependent value.
The amount of water is the dependent value.
The amount of rice is the independent value.
The amount of water is the independent value.
The values cannot be labeled as dependent or independent without a given equation.
Answers
Answer:
3 and 4 or C and D
Step-by-step explanation:
The independent value is the quantity of rice. The dependent value is the volume of water. B and C are the appropriate choices.
What is a ratio?An ordered pair of numbers a and b, expressed as a / b, is a ratio if b is not equal to 0. An equation that balances two ratios is known as a percentage. The numerical relationship between the two numbers illustrates how frequently one value contains or is contained within another.
Regarding the ratio of rice to water, the adages "The amount of rice is the independent value" and "The amount of water is the dependent value" are applicable.
The amount of rice is the independent value because it is the value that is being varied or controlled in the ratio. The amount of water is the dependent value because it depends on the amount of rice used in the ratio.
Therefore, the correct options are:
The independent value is the quantity of rice.
The dependent value is the volume of water.

One restaurant sells a large cheese pizza for $8.25 and charges $1.25 per topping added. Another place charges $9.00 for a large cheese pizza and $1.00 per additional topping. If you buy a pizza from each place, both with the same number of toppings, how many toppings need to be put on each one for the pizzas to cost the same amount?
Answers
Answer:
3
Step-by-step explanation:
You take 8.25+1.25 and get 9.5. Then you add 9.5 and add it again, until you get a whole number. Then 9+3 is also 12 so, you answer is 3 toppings.

1 bag is 2/5 kg.
The customer wants to buy 4 kg. So you need to multiply the single bag for a number that will give you 4 in total.
Here is an example with whole numbers, 8nstead of fraction. if the bag was 2 kg, and you want a total of 4kg. You need to multiply that 2 by a number x to get to your total 4. so you will have 2 * x = 4
That’s why you have 2/5 * x = 4
to isolate x, you need to devide both side by 2/5.
2/5 * x = 4
: 2/5 : 2/5 (Divide both sides by 2/5)
x = 4 : 2/5

Given that Paula has 35 unique puzzle pieces
So, the method of organizing possible pictures can she create dependent on each other to succeed.
There is an arrangement process
It is equal to the permutation of 35 numbers
⇒ ³⁵P₃₅
The formula of ⁿPₓ = n!/(n-x)!
⇒ 35!/(35-35)!
⇒ 35!/0! [∵ 0! = 1]
⇒ 35!
Hence, Paula can create number of possible ways of pictures are 35!.

Tony hit 9 out of 15 pitches at baseball practice yesterday. What percentage of the pitches did Tony NOT hit?
Answers
Answer:
5%
Step-by-step explanation:
Answer:
40%
Step-by-step explanation:
using the box method,
multiply 9 × 100
= 900 and divide 900 by 15
900 ÷ 15 = 60%
60% is the amount of pitches he hit
100% - 60% = 40%
he missed 40%
Consider the line y = 4x-3.
Find the equation of the line that is perpendicular to this line and passes through the point (3, -3).
Find the equation of the line that is parallel to this line and passes through the point (3, -3).
Answers
Answer:
perpendicular line: y = -[tex]\frac{1}{4}[/tex]x - [tex]\frac{9}{4}[/tex]
parallel line: y = 4x - 15
Step-by-step explanation:
Perpendicular line:
A perpendicular line to y = 4x-3 would have a slope that is the negative reciprocal (flip the fraction and add a negative sign). The negative reciprocal of 4 is - [tex]\frac{1}{4}[/tex].
Now that we have our slope, we can plug the given point of (3, -3) into the slope-intercept equation to find b.
-3 = - [tex]\frac{1}{4}[/tex](3) + b
-3 = - [tex]\frac{3}{4}[/tex] + b
Add [tex]\frac{3}{4}[/tex] to each side of the equation to isolate b.
-[tex]\frac{9}{4}[/tex] = b
Now we can write our equation, y = -[tex]\frac{1}{4}[/tex]x - [tex]\frac{9}{4}[/tex]
Parallel Line:
A parallel line to y = 4x-3 has the same slope. To find the equation, plug the slope and given point (3, -3) into the slope intercept equation and solve for b.
-3 = 4(3) + b
-15 = b
Now you can write the equation, y= 4x -15
Marcus is considering two car rental plans. Plan A can be modeled with the equation C=30d, and Plan B can be modeled with the equation C=25d + 15, where C represents the cost in dollars and d represents the number of days a car is rented. Which statement would justily selecting Plan B instead of Plan A
A.Marcus rent a car for 1 day
B.Marcus rent a car for 2 days
C.Marcus rent a car for 3 days
D.Marcus rent a car for 5 days
Answers
Answer:
D. Marcus rent a car for 5 days
Step-by-step explanation:
You can solve this by simply plugging the answer choices into the variable d for both equations and comparing the total costs.
When you plug in 5 days you get:
Plan A
C = 30 x 5
C = 150
Plan B
C = 25 x 5 + 15
C = 140
The cost is less for Plan B in this case, so it is better to use Plan B when renting for 5 days.
For values of h very close to 0, which function best approximates (tan(x+5)-tan x) / h
Answers
Answer:

Step-by-step explanation:
This just means, what is the derivative of tan(x)The function that best approximates the given situation is sec²x.
We have to find
[tex]\lim_{h \to\00} \frac{tan(x+h)-tan x}{h}[/tex]
Since the given expression reduces to 0/0 form when we apply the limits
So, let us apply the L'hospital rule
What is the L'hospital rule to find a limit?L'Hospital's Rule tells us that if we have an indeterminate form 0/0 or ∞/∞ all we need to do is differentiate the numerator and differentiate the denominator and then take the limit.
So, after differentiating the numerator as well as the denominator of the given expression with respect to h we get
[tex]\lim_{h \to\00} \frac{sec^2(x+h)-0}{1}[/tex]
[tex]= lim_{h \to\00} \frac{sec^2(x+0)}{1}\\\\= sec^2x[/tex]
Therefore, the function that best approximates the given situation is sec²x.

Answers
The equation of the line is y = (2/3)x -1
What is a slope?In mathematics, a line's slope, also known as its gradient, is a numerical representation of the line's steepness and direction.
From the given graph, we have two points (0, 1) and (3,3)
If a line passes through two points (x₁ ,y₁) and (x₂, y₂) ,
then the equation of line is
y - y₁ = (y₂- y₁) / (x₂ - x₁) x (x - x₁)
y - 1= (3 -1 ) / (3 -0) x (x -0)
y = (2/3)x -1
The equation of the line is;
y = (2/3)x -1 {equation 1}
Slope intercept form of a line is
y = mx + b {equation 2} ,
where m is the slope and b is the y-intercept.
On comparing the equation (1) and (2) we get
It means,
Slope = 2/3
y-intercept = -1
Therefore, the equation of the line is y = (2/3)x -1
