When it is about 68°F, crickets chirp 124 times a minute. When it is about 80°F, they chirp 172 times a minute. WRITE an equation in POINT SLOPE FORM for the line that models this situation.
Answer:
4x+148
Step-by-step explanation:
Let the temperature be x and time taken by cricket to chirp be y
if when it is about 68°F, crickets chirp 124 times a minute, this means;
at x1 = 68, y1 = 124
If it is about 80°F, they chirp 172 times a minute, then;
at x2 = 80, y2 = 172
The standard form of equation in point slope form is expressed as;
y-y0 = m(x-x0)
m is the slope
(x0, y0) is a point on the line.
First we need to get the slope.
m = y2-y1/x2-x1
m = 172-124/80-68
m = 48/12
m =4
Substitute m = 4 and any point into the expression above. Using the coordinate (68, 124)
get the intercept c
124 = 4(68) + c
c = 272-124
c = 148
The required equation is expressed as y = 4x+148 OR y - 124 = 4(x-68)
y/-8 = 1/16
find y. thank you!
Answer:
-0.5
Step-by-step explanation:
The answer is -0.5. We know this because with fractions you can multiply the top and bottom to make them = each other. we multiply the 8 by 2 to get -16. and we need the top to be half of 1 so 0.5. the 0.5 needs to be negative so they can = a positive in the final equation.

One number is 2 times another. The sum of their reciprocals is 6. Find the numbers.
The numbers are
Answer:
1/2, 1/4
Step-by-step explanation:
Let the numbers be x and y.
Given, x=2y
1/x + 1/y = 6
plug in x=2y ,
1/2y+1/y = 6
Taking common denominator ,
(1+2)/2y = 6
2y = 3/6 = 1/2 => y=1/4
x = 2y = 2* 1/4 = 1/2
So, the numbers are 1/2 and 1/4
Write equation of the line with the given slope and Y intercept.
Slope = 1/2.
Y-intercept = 7.
Answer:
y = 1/2x + 7
Step-by-step explanation:
The equation is y = mx + b where m is the slope and b is the y-intercept. So you simply plug in 1/2 for m and 7 for b and you get y = 1/2 +7

Ilona is at a friend's home that is several miles from her home. She starts walking at a constant rate in a straight line toward her home. The expression -2t+10 gives the distance in miles that Ilona is from her home after t hours
Complete question is;
Ilona is at a friends home that is several miles from her home. She starts walking at a constant rate in a straight line toward her home.
The expression -2t + 10 gives the distance, in miles, that Ilona is from her home after t hours. Select True or False for each of the following.
1. The friends home is 10 miles from Ilonas home
2. The distance Ilona has walked away from her friends home after t hours is given by the absolute value of -2t
3.The negative sign in the term indicates that Ilona is walking toward her home
4. Ilona is walking at a rate of 10 miles per hour
Answer:
Statements 1 & 2 are correct.
Step-by-step explanation:
We are told that the expression -2t + 10 gives the distance, in miles, that Ilona is from her home after t hours.
Now, we know that distance = speed x time
Now, from the expression -2t + 10
It's clear that 2t is a distance value.
This means that the speed used in going home is 2 miles/hr
This means that at t hours, she has walked 2t miles from her friends home.
Thus, statement 2 is true because an absolute value of -2t will be 2t.
Since 2t is subtracted from 10 in the expression and 2t is the distance she has walked from her friends house at Time, t. It means that 10 miles is the distance from her friends house to her house.
Thus, statement 1 is also true

Consider the rational number 3/11 a. What are the value of a and b in a divide by b when you use division to find the decimal form b. What is the decimal form for 3/11
Answer:
The decimal form of this rational number is [tex]0.\overline {27}[/tex].
Step-by-step explanation:
a) Let [tex]\frac{a}{b}[/tex] a rational number. From statement we understand that [tex]a[/tex] represents the numerator, while [tex]b[/tex] corresponds with the denominator of the rational number. Hence, [tex]a[/tex] is 3 and [tex]b[/tex] is 11.
b) The decimal form is obtained by dividing [tex]a[/tex] by [tex]b[/tex], we presented the step needed to determine the decimal form:
i) Multiply the numerator by 10:
Dividend: 30/Divisor: 11/Known result: 0. /Residue: N/A
ii) Multiply the divisor by 2 and subtract from the dividend:
Known result: 0.2 /Residue: 8
iii) Multiply the residue by 10:
Known result: 0.2 /Residue: 80
iv) Multiply the divisor by 7 and subtract from the residue:
Known result: 0.27 /Residue: 3
v) Multiply the residue by 10:
Known result: 0.27 /Residue: 30
vi) Multiply the divisor by 2 and subtract from the residue:
Known result: 0.272/Residue: 8
vii) Multiply the residue by 10:
Known result: 0.272 /Residue: 80
viii) Multiply the divisor by 7 and subtract from the residue:
Known result: 0.2727/Residue: 3
We have notice that the decimal form of [tex]\frac{3}{11}[/tex] is a periodical decimal number. Hence, we conclude that decimal form of this rational number is [tex]0.\overline {27}[/tex].

Step-by-step explanation:
∣x−10015∣∣≤23
where x is a person’s IQ. Solve the inequality to find the IQ scores for the middle 50% of the population.
Answer:
9992≤x 10038Step-by-step explanation:
Given the expression
∣x−10015∣∣≤23, we are to find the range of values of x
since the function is in a modulus sign, it can be expressed as a negative and positive function.
If the function is positive;
x - 10015 ≤23
x ≤23 + 10015
x ≤ 10038
If the function is negative;
-(x-10015)≤23
-x+10015≤23
-x≤23-10015
-x≤-9992
multiply through by -1
x ≥ 9992 (note the inequality sign change)
9992≤x
Combine both inequalities
9992≤x and x ≤ 10038
On combining;
9992≤x 10038
Hence the inequality to find the IQ scores for the middle 50% of the population is expressed as 9992≤x 10038
We want to solve an inequality to find the range of IQ scores for half of the population.
We will find that the range is:
77.15 ≤ x ≤ 123.15
The inequality we need to solve is:
|x - 100.15| ≤ 23
To solve it, we write two inequalities.
x - 100.15 ≤ 23
x - 100.15 ≥ -23
Solving these two, we will get the maximum and minimum of the range.
The maximum is given by:
x - 100.15 ≤ 23
x ≤ 23 + 100.15 = 123.15
The minimum is given by:
x - 100.15 ≥ -23
x ≥ -23 + 100.15 = 77.15
Then the range is:
77.15 ≤ x ≤ 123.15

Answer:
C) 25
Step-by-step explanation:
The exponents are only even numbers, which are divisible by 2.
If the last number is 50, divide it by 2.
1 to whatever power will always be 1 and there are 25 numbers, so 25.
Answer:
C) 25
Step-by-step explanation:
1 to the power of anything will always be 1, so we can eliminate the exponents. Now, we're left with 1 + 1 + 1 + ... + 1. The question is, how many 1s are in this list? We can refer back to the original problem to figure this out. Notice that the exponents are every other number from 1 to 50, so the number of 1s in the list is 50 / 2 = 25. Therefore, the answer is 25 * 1 = 25. Hope this helps!
