Answer:
-7 & 9
Step-by-step explanation:
(-7) + 9 = 2
(-7) - 9 = -16
x + y = 2
x - y = -16
Add the equations together to eliminate one of the variables.
2x = -14
Divide both sides by 2
x = -7
Let's plug -7 into x for our first equation.
-7 + y = 2
Add 7 to both sides.
y = 9

Answer:
A.true
Step-by-step explanation:
The domain of a quadratic function in standard form is always all real numbers, meaning you can substitute any real number for x. The range of a function is the set of all real values of y that you can get by plugging real numbers into x.

-4c+25+c=3c+79
Answer:
c = -9
Step-by-step explanation:
- 4c + 25 + c = 3c + 79 Combine like terms.
- 4c + c + 25 = 3c + 79
- 3c + 25 = 3c + 79
- 3c + 3c + 25 = 3c + 3c + 79
25 = 6c + 79
25 - 79 = 6c + 79 - 79
- 54 = 6c
-54/6 = 6c/6
-54/6 = c
-9 = c
There aren't 2 answers, you could have 2 answers if one of the c's was squared. Here is another way to do the math.
- 4c + 25 + c = 3c + 79
- 4c + c + 25 = 3c + 79
- 3c + 25 = 3c + 79
- 3c - 3c + 25 = 3c - 3c + 79
- 6c + 25 = 79
- 6c + 25 - 25 = 79 - 25
- 6c = 54
- 6c/- 6 = 54/- 6
c = 54/- 6
c = - 9
Answer:
-9 = c
Step-by-step explanation:
-4c+25+c=3c+79
-3c +25 =3c+79
25 = 6c +79
-54=6c
-54/6 = c
-9 = c
I don't see how there is a 2nd answer.

Answer:
3x^3 + 17x^2 + 21x - 9
Step-by-step explanation:
Use distributive property.
First distribute the 3x
3x times x^2 + 6x + 9. Distribute = 3x^3 + 18x^ 2 + 27x
Now we distribute the -1
-1 times x^2 + 6x + 9. Distribute = -x^2 -6x - 9
We Add both answers-
3x^3 + 18x^2 + 27x
+ -x^2 -6x - 9

owenn goes on a camping trip with his family cabin rentals are $430 for the week, kayak rentals are $7 per hour and paddle boards are $9 an hour, write an algebric expression to represent how much the family will spend if they stay for one week and plan on renting both kayaks and paddle boards while on their tripoi
Answer:
430 + 16h
Step-by-step explanation:
They are staying for a week ($430)
They are renting both a kayak ($7 per hour) and paddle board ($9 per hour), without defining the amount of hours. Create a variable, for example H for hours.
To create the expression, take the $430, the $7 per hour and $9 per hour, or 430 + 16h.

A leg of a right triangle measures 12 cm. The hypotenuse of the triangle measures 37 cm. What is the measure, in centimeters of the other
leg of the triangle?
25
35
39
49
Answer:
The answer is 35Step-by-step explanation:
Since the triangle is a right angled triangle we can use Pythagoras theorem to find the missing side b
Using Pythagoras theorem we have
a² = b² + c²
where a is the hypotenuse
Substitute the values into the above formula and solve
That's
[tex] {37}^{2} = {b}^{2} + {12}^{2} \\ {b}^{2} = {37}^{2} - {12}^{2} \\ { b}^{2} = 1369 - 144 \\ {b}^{2} = 1225 \\ b = \sqrt{1225} [/tex]We have the final answer as
35Hope this helps you
Answer:
35
Step-by-step explanation:
To solve for the hypotenuse of a right triangle, we use the Pythagorean Theorem, which is an equation to solve for the length of the hypotenuse given the two sides. The equation is a^2+b^2=c^2, where A and B are the legs of the triangle, and C is the hypotenuse. Let's manipulate this equation now. We are given one leg and the hypotenuse length, so the equation would be 12^2+b^2=37^2. Since we are trying to find the length of one of the legs, you subtract 12^2 from 37^2 to isolate B, and you get B^2 as 1225. You take the square root of both sides, and then you get 35 as the answer.

The ratio of boys to girls in a class is 5:7. There are 36 students in the
class. How many students are boys?
Answer:
15
Step-by-step explanation:
The ratio has been simplified so it may be hard to read.
To fix this multiply both the 5 and 7 by 3
This will give you 15:21
15 + 21 = 36 which is the total number of students.
Keeping the ratio in the same order means that there are 15 boys.
Answer:
There are 15 boys in the class.
Step-by-step explanation:
There are several ways to solve this, but here's how I did it:
5 (boys) : 7 (girls) = 12 students. There are 26 students, so we need to multiply this by 3.
15 (boys) : 21 (girls) = 36 students.
