Here, [tex]x[/tex] represents temperature and [tex]y[/tex] denotes rate of chirping per minute.
Step-by-step explanation:
Let [tex]x[/tex] represents temperature and [tex]y[/tex] denotes rate of chirping per minute.
At [tex]106[/tex]°F, a certain insect chirps at a rate of [tex]67[/tex] times per minute.
Take [tex](x_1,y_1)=(106,67)[/tex]
At [tex]108[/tex]°F, they chirp [tex]83[/tex] times per minute.
Take [tex](x_2,y_2)=(108,83)[/tex]
Slope intercept form:
[tex]y-y_1=(\frac{y_2-y_1}{x_2-x_1})(x-x_1)[/tex]
[tex]y-67=(\frac{83-67}{108-106})(x-106)\\\\y-67=(\frac{83-67}{108-106})(x-106)\\\\y-67=(\frac{16}{2})(x-106)\\\\y-67=8(x-106)\\y-67=8x-848\\y=8x+67-848\\y=8x-781[/tex]
Redbox rents out both video games and movies. They charge $2 for each video game and
$1 for each movie rented. Last week the total number of rentals was 114 and the machine
made a total of $177. How many movies and games were rented? What are the two
equations we can make? One is about the price, the other is the total rentals.
Answer:
1x + 2y = 177 (price)
x + y= 114 (rentals)

Answer:

total degree inside pentagon is (n - 2) x 180 = 540
180-62 = 118
180-66 = 114
180-77 = 103
180-59 = 121
118+114+103+121 = 456
540 - 456 = 84
84 + 12x = 180
12x = 180-84
x = 96/12
x = 8
The value of x in the given pentagon is 8.
Option D is the correct answer.
What is a Pentagon?A pentagon is a polygon that has five sides and five angles.
The sides and angles of a pentagon are not all equal unless it is a regular pentagon.
A regular pentagon has five equal sides and five equal angles.
We have,
For a pentagon, n = 5, so we have:
total degree = (5 - 2) × 180 degrees
total degree = 3 × 180 degrees
total degree = 540 degrees
Now,
Each angle makes a straight angle.
So,
77 + a = 180
a = 180 - 77 = 103
59 + b = 180
b = 180 - 59 = 121
c + 66 = 180
c = 180 - 66 = 114
d + 62 = 180
d = 180 - 62 = 118
Now,
a + b + c + d + e = 540
103 + 121 + 114 + 118 + e = 540
e = 540 - 456
e = 84
Now,
12x + 84 = 180
So,
12x = 180 - 84
12x = 96
x = 8
Thus,
The value of x is 8.

Answer:
35 cookie dough orders
Step-by-step explanation:
Juan and Rob are selling cookie dough for a school fundraiser. Juan has t cookie dough orders, and Rob has 40 cookie dough orders. They have a total of 75 cookie dough orders all together.
We have to calculate the number of cookie dough that Juan has.
The expression for the above question is given as:
t + 40 = 75
We collect like terms
t = 75 - 40
t = 35
Therefore, Juan has 35 cookie dough orders

I believe (x+5)(x-2) would be equal though.
Step-by-step explanation:
(x-5)(x+2) = x²+2x-5x-10
simplify:
x²-3x-10 ≠ x²+3x-10
(x)(x+3) = x²+3x
simplify:
x²-3x ≠ x²+3x-10
(x+3)(x-10) = x²-10x+3x-30
simplify:
x²-7x-30 ≠ x²+3x-10

The length of a rectangle is 1 foot more than twice the width. The area is 55 square feet. Find the length of the dimension of the rectangle.
Answer:
11 ft
Step-by-step explanation:
The formula for the area of a rectangle of length L and width W is
A = L * W.
Represent the length, L, by 2W + 1 ("1 more than twice the width"). Then the area formula (above) becomes:
A = 55 ft^2 = (2W + 1)(W), which, when simplified, results in:
2W^2 + W - 55 = 0, whose coefficients are {2, 1, -55}. Let's use the quadratic formula to solve this for W:
The discriminant, b^2 - 4ac, is 1^2 - 4(2)(-55), or 441. The square root of 441 is 21. Thus, the quadratic formula gives us:
-1 ± 21
W = ------------- = (1/4)(-1 + 21), or W = 5 and W = -22/4 = -11/2
2(2)
A measure of length can't be negative, so we reject W = -11/2 in favor of W = 5.
Then, according to the formula for L that we found earlier, L = 2W + 1, or
L = 2(5) + 1, or L = 11.
Check: Does L * W result in an area of 55 ft²? Yes
The length dimension of the rectangle is 11 ft
