Answer:
The integer which represents the change in temperature from morning to afternoon is -11°
Step-by-step explanation:
Since the morning temperature in Erin's apartment was 79°, and the temperature in Erin's apartment that afternoon was 68°. If Erin turned up the temperature and the temperature in the afternoon was 68°. So, the temperature change from 79° down to 68° is thus 68° - 79° = -11°.
So, the integer which represents the change in temperature from morning to afternoon is -11°

What is the degree of rotational symmetry for the following figure?
Answer with step-by-step explanation:
For a figure or object that has rotational symmetry, the angle of turning during rotation is called the angle of rotation. Example: when a square is rotated by 90 degrees, it appears the same after rotation. So, the angle of rotation for a square is 90 degrees.

Step-by-step explanation:
F(x)= 2x^2-3x-9 G(x)= 4x^2-9 find (f/g) (x)
This is about division of polynomials.
(f/g)(x) = (x + 1)/(2x + 3)
(f/g) (x) simply means we divide f(x) by g(x) We are given;f(x) = 2x² - 3x - 9
g(x) = 4x² - 9
To divide this, let's simplify each function to its factors using the sun-product pattern.f(x) = 2x² - 3x + 6x - 9
Let's collect like terms;
f(x) = x(2x - 3) + 1(2x - 3)
Rewriting in factored form gives;
f(x) = (x + 1)(2x - 3)
Similarly;g(x) = 4x² - 9
g(x) = 4x² + 6x - 6x - 9
g(x) = 2x(2x + 3) - 3(2x + 3)
Rewriting in factored form gives;
g(x) = (2x + 3)(2x - 3)
Thus;
(f/g)(x) = ((x + 1)(2x - 3))/((2x + 3)(2x - 3))
(f/g)(x) = (x + 1)/(2x + 3)

PLEASE HELP I WILL MARK BRAINLIEST
Answer:
i think its 64.66
Step-by-step explanation:
07x53=3.71
0.15x53=7.95+53=60.95+3.71=64.66
Answer:
$64.66
Step-by-step explanation:
find the amount of tax 53 x .07 = 3.71
find the amount of the tip 53 x .15 = 7.95
53 + 3.71 + 7.95 = 64.66
Which number goes in the
space (?) to make the two
fractions equivalent
3/8 = 15/?
Answer:
40 mark Brainliest please
Step-by-step explanation:
15/40
Let the missing number be x .
Then :-
[tex] \frac{3}{8} = \frac{15}{x} [/tex]
[tex] 3 \times x = 8 \times 15[/tex]
[tex]3x = 120[/tex]
[tex]x = \frac{120}{3} [/tex]
[tex]x = 40[/tex]
The missing number is 40 .
Let us check it by doing cross multiplication :-
[tex]3 \times 40 = 15 \times 8[/tex]
[tex]120 = 120[/tex]
Hence proved the missing number is 40 .
[tex]therefore \: , \frac{3}{8} = \frac{15}{40} [/tex]

Which of the following lines is perpendicular to the equation given below?
y = -2x + 8
2x + y = 4
2x + y = 4
x - 2y = 6
x - 2y = 6
2x - y = 1
2x - y = 1
x + 2y = 8
the anser is
x- 2 y =6
x- 2 y =6
thats iit

Elsa Is taking physical fitness tests in her strength training class. Each day, her results are compared to her resutts from previous days. The first day she completes a test is considered the baseline, and Is represented by 0. For instance, on the first day she did the flexibility test, her result was calculated as 0. On the second day, in comparison to her first day's result, she was able to reach 1 1/16 inches less than the first day, which was recorded as -1 1/16. Then, on the third day, Elsa recorded a result of -5/8.
A. On which day did Elsa reach farther: the second or third day?
B. By how much?
Answer:
A) The second day
B) 9/16 inches
A) Elsa reached farther on the second day because -1/16 > -5/8
B) To calculate this we must first put both fractions above the same denominator. We can then subtract the smaller one from the bigger one:
-1/16 - (-10/16) = 9/16
Elsa reached 9/16 inches farther on the second day then she did on the first.
Hope this helps and have a great day!
Also stay safe! :))))
Fairly easy question
What is the solution to this system of equations?
x − 2y = 15
2x + 4y = -18
A.
x = 1, y = -6
B.
x = 1, y = -7
C.
x = 3, y = -6
D.
x = 3, y = -7
Answer:
C. x=3 and y=−6
Step-by-step explanation:
Step: Solvex−2y=15for x:
x−2y=15
x−2y+2y=15+2y(Add 2y to both sides)
x=2y+15
Step: Substitute2y+15forxin2x+4y=−18:
2x+4y=−18
2(2y+15)+4y=−18
8y+30=−18(Simplify both sides of the equation)
8y+30+−30=−18+−30(Add -30 to both sides)
8y=−48
8y8=−488(Divide both sides by 8)
y=−6
Step: Substitute−6foryinx=2y+15:
x=2y+15
x=(2)(−6)+15
x=3(Simplify both sides of the equation)
Answer:
x=3 and y=−6

Two adults and 9 students cost $50 to attend
the game. If one adult and 8 students cost
$39 how much do adult and student tickets
cost?
Answer:
The cost of tickets for a play is $3.00 for adults and $2.00 for children. 350 tickets were sold and $950 was collected. How many tickets of each type were sold?
Let x = number of $3 tickets
Let y = number of $2 tickets
Total = quantity × value
Step-by-step explanation:
x + y = 350 (equation 1)
3x + 2y = 950 (equation 2)
Use Substitution Method
Isolate variable x in equation 1
x = 350 – y (equation 3)
Substitute equation 3 into equation 2
3(350 – y) + 2y = 950
1050 – 3y + 2y = 950
3y – 2y = 1050 – 950
y = 100
Substitute y = 100 into equation 1
x + 100 = 350
x = 250
Answer: 250 $3 tickets and 100 $2 tickets were sold.

Answer:
D
Step-by-step explanation:
Answer:
D
Step-by-step explanation:
The initial fee of $12 would be the y-intercept because no matter how many boxes of cards you buy, the fee stays the same. The slope would be $3.99 because that fee is charged per box. The 100 cards per box is extra information and not needed in the equation. D is the only logical choice.

PLEASE HURRY A triangle and two of its side lengths are shown in the diagram. Which measurement is closest to the value of x in feet? The diagram show a triangle that has 3.7ft on the left side, 14.3 ft on the right/slanted side, and x at the bottom PLEASE HELP ME
Answer:
[tex] x = 13.8 ft [/tex]
Step-by-step explanation:
Since it's a right triangle, apply pythagorean theorem.
The formula is given as a² + b² = c²
Where,
a = 3.7 ft
c = 14.3 ft
b = x
Plug in the values into the formula:
[tex] 3.7^2 + x^2 = 14.3^2 [/tex]
[tex] 13.69 + x^2 = 204.49 [/tex]
Subtract 13.68 from both sides
[tex] x^2 = 204.49 - 13.69 [/tex]
[tex] x^2 = 190.8 [/tex]
[tex] \sqrt{x^2} = \sqrt{190.8} [/tex]
[tex] x = 13.8 [/tex] (nearest tenth)

what is 25 2/3 - 15 1/3 =
Answer:
10 1/3
Step-by-step explanation:
Convert mixed numbers into improper fractions (whole number × denominator + numerator)
25 2/3 and 15 1/3
25 × 3 + 2 = 75 + 2 = 77
Put the number over the same denominator
77/3
15 × 3 + 1 = 45 + 1 = 46
Put the number over the same denominator
46/3
77/3 - 46/3
They have common denominators so we can simply subtract the numerator values
77 - 46/3
31/3
To convert it back to a whole number, find how many times 3 fits into 31 evenly
It fits 10 times evenly with 1 remainding which looks like:
