Answer:
y = 5 and x = 2
Step-by-step explanation:
Since we have x = -3y + 17, we're going to substitute this equation into the x-value in the second equation.
2(-3y + 17) - y = -1
Multiply the 2 with the terms within the parentheses.
-6y + 34 - y = -1
Add the y values.
-7y + 34 = -1
Subtract 34 from both sides.
-7y = 35
Divide each side by -7.
y = 5
Now that we know the value of y, we can substitute 5 for the y-value in the first equation.
x = -3(5) + 17
Multiply.
x = -15 + 17
Add the two terms together.
x = 2

Answer:
x=3
Step-by-step explanation:
First we have to get x by itself-
8-6x=18x If you add 6x to -6x it chancels out
+6x +6x
8=24x Now we have to divide by 8

Step-by-step explanation:
3 (n-4) = 36
3n -12=36
add twelve to both sides. because -12 + 12 is 0. and once you are at zero, you can cancel it out.
3n=48
divide by 3 on both sides
n=16

Answers
1. put one equation on top of the other, and you are going to be adding the equations together
The x’s will eliminate when you add them, because -x+x=0
now you must add together the y’s, as well as the numbers on the other side of the equal sign.
3. solve for “y”
4. plug the y value you get into either of the original equations, “x+2y=6” or “-x-3y=-7”

:):):)
:):);):)
Answer:
The ans is 0.8
Step-by-step explanation:
80% = 0.8 in decimal form.
Percent means 'per 100'. So, 80% means 80 per 100 or simply 80/100.
If you divide 80 by 100, you'll get 0.8 (a decimal number). Read more below on this webpage.
As you can see, to convert from percent to decimal just divide the percent value (80) by 100, and remove the "%" sign.

Answers
Answer:
Step-by-step explanation:
x/4-y/2=8, x-2y=32, x=32+2y
x/2+3y/4=-5, 2x+3y=-20, x=(-20-3y)/2
32+2y=(-20-3y)/2
64+4y=-20-3y
7y=-84
y=-12, since x=32+2y
x=32+2(-12), x=32-24=8

For which function would f(3) = 17
A)f(x) = 3x+6
B)f(x) = 2(x + 4)+3
C) f(x) = 5x
Answers
A function is defined as a relation between a set of inputs having one output each.
The function that would give f(3) = 17 is
f(x) = 2 ( x + 4 ) + 3
What is a function?A function is defined as a relation between a set of inputs having one output each.
We have,
f(3) = 3x + 6
Substitute x = 3
f(3) = 3 x 3 + 6 = 9 + 6 = 15
f(x) = 2 ( x + 4 ) + 3
Substitute x = 3
f(3) = 2 ( 3 + 4 ) + 3 = 2 x 7 + 3 = 14 + 3 = 17
f(x) = 5x
Substitute x = 3
f(x) = 5 x 3 = 15
We see that f(x) = 2 ( x + 4 ) + 3 gives the 17 at x =3.
Thus the function that would give f(3) = 17 is
f(x) = 2 ( x + 4 ) + 3

5x -2y = 88
3x+4y=58
Answers
Answer:
x=18
Step-by-step explanation:
add 2y to both sides 5x=2y+88
subtract 88 from both sides 2y=5x-88
substitute 2y in the second equation for 5x-88
3x+10x-176=58
add like terms 13x-176=58
add 176 both sides
13x=234
x=18
Answer:
( 18, -6.5 )
Step-by-step explanation:
First choose which method you plan on using: Substitution or Elimation. I chose elimination based off preference.
How to solve using Elimination:
5x -2y = 88 (multiply every number in this equation by two)
3x+4y=58
10x -4y = 176
3x+4y=58 (combine these two equations)
13x = 234 (isolate x by dividing by 13 on both sides)
x = 18 (this is your value for x)
3(18) +4y=58 (plug in for x)
54+4y=28 (solve)
4y = -26 (subtract 54 from both sides)
y = -6.5 (this is y)
write answer in (x, y) format
( 18, -6.5 )
An online store charges a few of $4.50 for shipping. There is an additional charge of $0.50 for each pound the item weighs. How much does the store charge to ship a hammock that weighs 10.54 pounds?
Answers
Answer:
The store charges $9.77 to ship a hammock that weighs 10.54 pounds.
Step-by-step explanation:
4.50 (shipping cost)
0.50 (per 1 pound)
w = weight in pounds
w=10.54
4.50+0.50w= total cost
sub in 10.54 for w
remember order of operations (PEMDAS)
4.50 + 0.50 (10.54) = 4.50 + 5.27 = 9.77
The store charges $9.77 to ship a hammock that weighs 10.54 pounds.
