Answer:
The solution in point form is (9,7) and the equation would be x+9, y=7
Step-by-step explanation:
By using moving the -4y to the right side and by flipping the signs you can turn the equation -x-4y=-37 into x=37-4y.
With this new equation you can use the substitution method and replace the x in -2x-5y=-53 with 37-4y, making it look like this: -2(37-4y)-5y=-53.
Then you solve for y getting y=7.
With the value of y, you can plug that into the equation x=37-4y so it will look like x=37-4(7)
Then you solve for x getting x=9
And with that you get the point (9,7)
Answer:
there is only one easy way to sole this
using quadratic equation
Step-by-step explanation:
a=6 b=5 c=-6
and by applying it to the equation you will get
x=0.66 and x=-1.5
Answer:
Your answer should be 15.905625, if it's not 15 percent off per pound.
Step-by-step explanation:
Multiply 4.99 x 3.75 then multiply that answer (18.7125) by .15
That will leave you with 2.806875, which then you subtract that from 18.7125
That will give you your answer, 15.90...
Answer:
y = 3x + 1
Step-by-step explanation:
Since we know the Graph is Parallel to y = 3x + 11, we know that the "mx" portion of the equation is 3x since only the "b" would be different.
Then we just substitute in the point and to find b.
4 = 3(1) + b
b = 1
y = 3x + 1 is the answer
Answer:
12, 14, and 16
Step-by-step explanation:
Assume
1st number: x
2nd number: x+2
3rd number: x+4
(I'm adding 2 for each number because even numbers skip by 2)
The numbers add to 42, so
x+(x+2)+(x+4)=42
x+x+2+x+4=42
3x+6=42
3x=36
x=12
1st number: 12
2nd number: 12+2=14
3rd number: 12+4=16
12, 14, and 16
