Use substitution to solve the system of equations.
3 - 5y = 36
22 + y = -16
Answer:
(-4, -8)
Step-by-step explanation:
x - 5y = 36; 2x + y = -16
first, rearrange the first equation by adding 5y to both sides to isolate x
x = 5y + 36
then plug that in for x in the second equation and solve for y:
2(5y +36) + y = -16 distribute 2 to (5y + 36)
10y + 72 + y = -16 combine like terms by adding 10y and y
11y + 72 = -16 subtract 72 from both sides
11y = -88 divide both sides by 11
y = -8
next, plug y in and solve for x
x - 5(-8) = 36
x + 40 = 36 subtract 40 from both sides
x = -4
finally, check the solution by plugging x and y into both equations to see if they equal the expected value
(-4) - 5(-8) = -1 + 40 = 36 = 36 ✓
2(-4) + (-8) = -8 -8 = -16 = -16 ✓

Answer:
416Step-by-step explanation:
For this to have infinitely many solutions, the left side and right side must simplify to the same expression. The left side is already simplified, so we need to find the right numbers for the right side.
Coefficient of x:
7x = __x + 3x
4x = __x . . . . . . subtract 3x; next divide by x
4 = __ . . . . . the required x-coefficient is 4
Constant term:
-8 = 8 -__
-16 = -__ . . . . . subtract 8
16 = __ . . . . . . multiply by -1
__
The numbers that go in the boxes are 4 and 16.

Answer:
x = [tex]\frac{ 7\sqrt{3} }{3}[/tex]
Step-by-step explanation:
7 = [tex]x\sqrt{3}[/tex]
x = [tex]\frac{7}{\sqrt{3}}[/tex]
multiply numerator and denominator by [tex]\sqrt{3}[/tex]
x = [tex]\frac{ 7\sqrt{3} }{3}[/tex]
Alex dumped out his piggy bank and there were only
nickels, dimes, and quarters.
There were three times as many dimes as nickels, and 40
more quarters than nickels.
If the total amount of money was $17.20, how many of each
type of coin were there?
"There are
nickels,
dimes, and
quarters.
Answer:
12 nickels
36 dimes
52 quarters
Step-by-step explanation:
Let x = no. of nickels
3x = no. of dimes
x + 40 = no. of quarters
5x = value of the nickels since each nickel is 5 cents
10(3x) = 30x = value of the dimes since each dime is 10 cents
25(x + 40) = 25x + 1000 = value of the quarters since each quarter is 25 cents
Now, 5x + 30x + 25x + 1000 = 1720 ($17.20 = 1720 cents)
60x + 1000 = 1720
60x = 720
x = 12 nickels
3x = 36 dimes
x + 40 = 52 quarters
Check: 12 nickels are worth $.60
36 dimes are worth $3.60
52 quarters are worth $13
.60 + 3.60 + 13 = 17.20

WILL GIVE BRAINLIEST Which of the following describes the quotient of 3 and -30?
A.
The quotient is an irrational number.
B.
The quotient is a rational number.
C.
The quotient is undefined.
D.
The quotient is an integer
Answer:
if i am correct the answer is A
Step-by-step explanation:
The quotient of 3 and -30 is a rational number. The correct answer would be an option (B).
What is the Quotient?A quotient is defined as the outcome of dividing an integer by any divisor that can be said to be a quotient. The dividend contains the divisor a specific number of times.
The quotient of 3 and -30 is:
3 ÷ (-30) = -0.1
Therefore, the quotient is a rational number. Option B is correct.
A rational number is a number that can be expressed as a ratio of two integers, where the denominator is not zero. In this case, -0.1 can be expressed as the ratio of the integer -1 and the integer 10, where the denominator 10 is not zero.
Note that the quotient is negative because we are dividing a positive number (3) by a negative number (-30).

Round 72.178 to the nearest hundredth.
Answer:
72.18
Step-by-step explanation:
The hundreth place is the second to the right of the decimal. So the number in the hundreths place is 72.178. When rounding, you look at the number behind the number you are rounding to. In this case, you want to look at the 8. If the number is 5 or above, you round up. 8 is above 5 so you round the 7 to an 8.
Answer: 72.18

What is linear inequality?Linear inequality refers to the relation between a linear algebraic expression to some known value that contains inequality sign.
Unlike a linear equation it can have a range of values inside an interval.
The given inequality can be solved as follows,
4x - 5 ≥ 7
Subtract 7 from both sides to obtain,
4x - 5 - 7 ≥ 0
=> 4x - 12 ≥ 0
=> 4x ≥ 12
=> x ≥ 3
The graph for the given inequality is shown as below,
Hence, the solution for the given inequality is x ≥ 3.

the path of a toy rocket is modelled by the equation y=-x^2+6x+2, where x is the horizontal distance, in metres, travelled and y is the height, in metres, of the toy rocket above the ground. what is the maximum height of the toy rocket? at what horizontal distance does the maximum height occur?
Answer:
The path of a toy rocket is defined by the relation y=-3x^2+11x+4, where x is the horizontal distance, in meters, traveled and y is the height, in metres, above the ground.
Determine the zeros of the relation.
-3x^2 + 11x + 4 = 0
---
3x^2 - 11x -4 = 0
Factor:
3x^2 - 12x + x - 4 = 0
---
3x(x-4) + x-4 = 0
---
(x-4)(3x+1) = 0
---
x = 4 or x = -1/3
============================
f(x) = -3x^2+11x+4
How far has the rocket traveled horizontally when it lands on the ground?
4 ft.
==================
What is the maximum height of the rocket above the ground, to the nearest hundredth of a meter?
---
max occurs when x = -b/2a = -11/(2*-3) = 11/6
height = f(11/6) = 14.083 ft

Hi! So what you will need to know is pythagorean theorm.
What the theorm basically says is a^2 + b^2 = c^2.
-- The (a,b,c) are referring to the sides of the triangles (3 letters for 3 sides).
Take note that "c" is always the side opposite of the right angle.
The other known side could be "a" or "b"
Taking a look at problem 9, identify the "c" value. The "c" value would be 35.
Then indentify the value of "b" or "a". "a" would = 20.
Plug it into the equation:
20^2 + b^2 = 35^2
400 + b^2 = 1225
solve for b.
1. subtract 400 from both sides.
b^2 = 825
b = [tex]\sqrt{825}[/tex]
you could solve for the square root but it would give a decimal numbers but I'm not sure what the teacher is looking for.
