Answer:
1) y= 2x
for every 5 x-steps to the right the graph goes up by ten. 10/5 is simplified to 2/1 or just 2
it starts at 0/0, so no need to add and absolute value
2) x: number of days
y: number of vidits (roughly2 per day, but you don't need to write this in the box)
3) 35 days. it's just y=70
and we could write this as
70 = 2*x | devide by 2 on both sides to get x
35 = x
Write a function to describe the following scenario.
The temperature of a hot steak starts at 140° F and decreases at 5° F per minute. What will the temperature be of this steak after a certain number of minutes?
y= ? - ?x
Answer:
Below.
Step-by-step explanation:
Temperature after 1 minute = 140 - 5(1)
Temperature after 2 minutes = 140 - 5(2)
Temperature after 3 minutes = 140 - 5(3),
- and so on.
So the function is
y = 140 - 5x.
The temperature of the steak after a certain number of minutes can be described as the function
y = 140 - 5x
What is a linear equation?A linear equation with one variable has the standard form Cx + D = 0. In this case, the variable is x and C are coefficient, while D is a constant.
How to solve this problem?Let the certain number of minute is x.
Since the temperature decreases at 5° F per minute, then after x minutes, it will decrease 5x.
Initial temperature = 140° F
Then the present temperature, y = 140 - 5x.
Therefore, the temperature of the steak after a certain number of minutes can be described as the function
y = 140 - 5x

For the given table of values for a polynomial function, where must the zeros of the function lie?
A. between 2.0 and 2.5 and between 4.0 and 4.5
B. between 2.5 and 3.0 and between 4.0 and 4.5
C. between 2.0 and 2.5 and between 3.5 and 4.0
D. between 2.5 and 3.0 and between 3.5 and 4.0
Answer:
(B). between 2.5 and 3.0 and between 4.0 and 4.5.
Step-by-step explanation:
According to the Question,
If the value of the function is 0 at x=c, then c is a root or zero of the function. It means the graph of function intersects the x-axis at its zeroes.From the given table it is clear that the value of function are
x | f(x) | Sign
2.0 | 2.8 | Positive
2.5 | 1.1 | Positive
3.0 | –0.8 | Negative
3.5 | –1.2 | Negative
4.0 | –0.3 | Negative
4.5 | 0.7 | Positive
The sign of values of function changes in interval 2.5-3.0 and 4.0-4.5. It means the graph of function must intersect the x-axis in intervals 2.5-3.0 and 4.0-4.5. So, the zeros of the function lie between 2.5 and 3.0 and between 4.0 and 4.5.Therefore, the correct option is B.
Which line is parallel with y = -3x + 10
Answer:
If a line is parallel with Another...
They will have the same Gradient or equal Gradient (m)
So for two parallel lines
m=m'
So the gradient of the second or other line would be Same
Now
y= -3x + 10
comparing with
y= mx + c
m = -3
So the other line would have the same gradient.
from the options provided in the comment section...
y= -3x + 12
Is your Most probable answer cos it has the same gradient

Sergio is buying plums at $1.60
per pound. He buys at least 1
pound. The weight of each plum
is a quarter of a pound. Sergio
states he can buy a number of
plums that cost exactly $3.80.
Complete Parts A and B to show
Sergio's statement is false.
PLEASE HELP QUICKLY NO LINKSS!
Answer:
Sergio's statement is false
Step-by-step explanation:
Cost of one pound of plum = 1.60
Total quantity of plum bought = 1
Weight of each plum = 1/4 pound
If he buys plum of $ 3.80 at the rate of $1.60 per pound, he purchases 2.375 pounds of plum
Weight of one plum = 1/4 pound, thus total number of plum purchased = 9.5
Since 0.5 pound of plum means half plum which is not possible to buy
Hence Sergio's statement is false

Answer:
Altitude of cylinder = 10 cm
Step-by-step explanation:
Given:
lateral surface area of cylinder = 90 cm²
Circumference of base = 9 cm
Find:
Altitude of cylinder
Computation:
Circumference of base = Circumference of cylinder
So,
2πr = 9
lateral surface area of cylinder = 2πrh
2πrh = 90
We know that; 2πr = 9
So,
9(h) = 90
h = 90 / 9
Altitude of cylinder = 10 cm
If P = (-3,5), find the image
of P under the following rotation.
90° counterclockwise about the origin
([?], [
[]
Enter the number that belongs in
the green box
Answer:
(-5 , -3)
Step-by-step explanation:
use formula of 90 degree counterclockwise rotation about the origin
formula:
(x , y) = (-y , x)
(-3 , 5) = (-5 , -3)
The required coordinate of the point after 90° clockwise rotation is (-5, -3).
What does it mean by rotation?A shape or item is rotated when it is spun around a certain point (center) without being moved in any other way. Size and shape are unaffected by rotation.
The given coordinate of the point is (-5, -3).
Counterclockwise rotation about the origin is given as,
(x , y) = (-y , x)
(-3, 5) = (-5 , -3)
Thus, the required coordinate of the point after 90° clockwise rotation is (-5, -3).

Answer:
[tex]y=\sqrt{x-5}[/tex]
Step-by-step explanation:
Answer:
The answer is [tex]y=\sqrt{x-5}[/tex].
Step-by-step explanation:
To solve for the inverse of this function, start by writing [tex]f(x)=x^{2} +5[/tex] as an equation, which will look like [tex]y=x^{2} +5[/tex].
Next, interchange the variables, and the equation will look like [tex]x=y^{2}+5[/tex]. Then, solve for the y in the equation,
To solve for the y in the equation, rewrite the equation as [tex]y^{2}+5=x[/tex]. Next, subtract 5 from both sides of the equation, which will look like [tex]y^{2}=x-5[/tex]. The next step is to take the square root of both sides of the equation to eliminate the exponent on the left side, and the equation will look like [tex]y=\sqrt{x-5}[/tex].
To put the answer in actual inverse form, the answer will be [tex]f^{-1} (x)=\sqrt{x-5}[/tex].

The probability that Jane will go to a ballgame (event A) on a Monday is 0.73, and the probability that Kate will go to a ballgame (event B) the same day is 0.61. The probability that Kate and Jane both go to the ballgame on Monday is 0.52.
From the given scenario, we can conclude that events A and B are
Answer:
dependent events since P(A and B) is not equal to P(A) * P(B)
Step-by-step explanation:
According to the Question,
Given, The probability that Jane will go to a ballgame (event A) on a Monday is 0.73, and the probability that Kate will go to a ballgame (event B) the same day is 0.61. The probability that Kate and Jane both go to the ballgame on Monday is 0.52.Thus, The events A, B and A∩B are:
A - Jane will go to a ballgame on Monday;
B - Kate will go to a ballgame on Monday;
A∩B - Kate and Jane both go to the ballgame on Monday.
P(A)=0.73, P(B)=0.61, P(A∩B)=0.52.Pr(A)⋅Pr(B) = 0.73⋅0.61 = 0.4453 ≠ 0.52So, events A and B are dependent events since P(A and B) is not equal to P(A) * P(B)
Answer:
From the given scenario, we can conclude that events A and B are dependent events since P(A and B) is not equal to P(A) * P(B)

Step-by-step explanation:
x+132 should be equal to 180, property of a parallelogram (and same side interior angles)
180-132=48
Answer:
x = 48
Step-by-step explanation:
Consecutive angles in a parallelogram sum to 180° , so
x + 132 = 180 ( subtract 132 from both sides )
x = 48
