Answer: x = 3; y = -2
Step-by-step explanation:
Simultaneous Equations:
3^(2x) x 3^(3y) = 3^0
2x + 3y = 0
2^(2x) x 2^(-0.5y) = 2^7
2x - 0.5y = 7
2x = -3y
-3y - 0.5 y = 7
y = -2
x = 3

x=3 y=-2

Answer:
a = 30
b = 15
c = 3
d = 30
e = 10
f = 20
Step-by-step explanation:
60 deg and a + 30 are alt int <S and congruent
a + 30 = 60
a = 30
a + 30 and a + 2b are corresponding angles and congruent
a + 2b = a + 30
2b = 30
b = 15
a + 2b and 5b - 5c are vertical angles and congruent
5b - 5c = a + 2b
5(15) - 5c = 30 + 2(15)
75 - 5c = 30 + 30
75 - 5c = 60
-5c = -15
c = 3
a + 2b and 10c + d are corresponding angles and congruent
10c + d = a + 2b
10(3) + d = 30 + 2(15)
d + 30 = 60
d = 30
5b - 5c and 2d + 6e are supplementary and add to 180
5b - 5c + 2d + 6e = 180
5(15) - 5(3) + 2(30) + 6e = 180
75 - 15 + 60 + 6e = 180
6e + 120 = 180
6e = 60
e = 10
2d + 6e and 4f + 4e are alt int angles and congruent.
4f + 4e = 2d + 6e
4f + 4(10) + 2(30) + 6(10)
4f + 40 = 60 + 60
4f + 40 = 120
4f = 80
f = 20

Stewart has a home-based business putting on children’s parties. He charges $60 to design the party and then $6.00 per child. Write a function rule that relates the total cost of the party to the number of children n.
f(n) = 6 + 60n
f(n) = 6n – 55
f(n) = 60 + 6n
f(n) = 6 – 55n
Answers
Answer:
f(n) = 60 + 6nStep-by-step explanation:
numbers of students = n
party decoration charge = 60
per child cost = 6
so, therefore
f(n) = 60 + 6n
MARK ME AS BRAINLISTPLZ FOLLOW MEAnswer: A. f(n) 60 + 6n
60 is constant
6 per child is variable
Let c = number of children
total cost = 60 +6c
Step-by-step explanation: i got it from somebody else's brainly
If there are n children, and each additional child who joins will add another $6 to the cost, then the cost due to the number of children will be 6n. We also have the fixed cost of $60, no matter how many children join. Therefore, we add up these costs to get Cost = f(n) = 60 + 6n.

What is the equation of a line that has a slope of -5 and passes through the point (0, 2)?
y = -5x
y = 2x - 5
y = -5x + 2
Answers
Answer:
y= -5x+2 is the equation.
Answer:
y= -5x + 2
Step-by-step explanation:
y = mx + b(we will put the points of "x" and "y" into this formula)
2= -5 (0) +b( as "x" is "0" and is multiplied by "-5" it will become "0" giving us the value of "b")
2=b(finally we will substitute this answer in the formula we've written)
therefore the answer will be:
y= -5x + 2
What is an equation of the line that passes through the point (6,1) and is perpendicular to the line 2x+3y=18?
Answers
Answer
y = 3/2x -8
Step-by-step explanation:
The first thing you should do is change the equation into slope intercept form. Subtract 2x from both sides to get: 3y = -2x + 18. Divide all parts of the equation by 3 to get your equation in slope intercept: y = -2/3x + 6. One thing you should know when finding the slope of a perpendicular line is that it is the opposite reciprocal. So, the slope is going to be 3/2. This is your current equation: y = 3/2x + b. Plug in the point to the equation, it should look like this: 1 = 3/2(6) + b. Multiply 3/2 by 6 to get 9. This is what it should look like: 1 = 9 + b. Then, subtract 9 from both sides of the equation to get your y-intercept of -8. Go back to your other equation and plug in -8 for b. This is your final equation: y = 3/2x -8.
3.) 4(m + 5) + 42, (m = -2)
Answers
Step one: 4(-2+5)+42
Step two: (-8+20)+42=54
Answer:
54
Step-by-step explanation:
The variable m equals -2, so what you would do is plug it into the equation.
4(-2+5)+42
Next you would distribute the 4 into -2 & 5.
(-8+20) + 42
Add what's in the parenthesis.
12 + 42
Once you add that you will be left with your answer which is 54.

Enter your answer in the box. (1/10 and 1/100 are fractions)
Answers
Answer:
500.61
Step-by-step explanation:
5 multiplied by 100 = 500
1/10 = 0.1, So 6 multiplied by 0.1 = 0.6
1/100 = 0.01, So 1 multiplied by 1 = 0.01
500 + 0.6 + 0.01 = 500.61
[tex](5 \times 100) + (6 \times \frac{1}{10} ) + (7 \times \frac{1}{100} )[/tex]
[tex]5 \times 100 = 500[/tex]
[tex] \frac{6}{1} \times \frac{1}{10} = \frac{6}{10} = 0.60[/tex]
[tex] \frac{7}{1} \times \frac{1}{100} = \frac{7}{100} = 0.07[/tex]
[tex]500 + 0.60 + 0.07 = 500.67[/tex]

Parallel lines have the same slope, so find the slope of this line
Use rise over run, (y2 - y1) / (x2 - x1)
(y2 - y1) / (x2 - x1)
(8 + 2) / (-1 - 4)
10 / -5
= -2
So, the slope of the line is -2
