I need help with this
Answer:
Nice pfp- Also, Elena would know because they have identical slopes and y intercepts, The Equation would give you 36x + 18 = 36 x +18, Basically they are corresponding lines.
hope that helped. :p
Anyone know the awnser to this it’s 28 points!and you have to give me the awnser to all of them
Answer:
The y-intercept is -6 and the x-intercept is 5
Step-by-step explanation:
I posted a picture on how I got this
Hope this Helped
Answer:
Find attached file also
Step-by-step explanation:
6x - 5y = 30
y intercept,Put x = 0
6*0 - 5y = 30
-5y = 30
y = 30 /-5
y = -6
x intercept,Put y =0
6x - 5*0 =30
6x = 30
x = 30/6
x =5

solve system by elimination
6.
2x + 5y = 14
4x + 2 y = -4
Answer:
x=−3 and y=4
Step-by-step explanation:
Multiply the first equation by -2,and multiply the second equation by 1.
−2(2x+5y=14)
1(4x+2y=−4)
Becomes:
−4x−10y=−28
4x+2y=−4
Add these equations to eliminate x:
−8y=−32
Then solve−8y=−32for y:
−8y=−32
−8y
−8
=
−32
−8
(Divide both sides by -8)
y=4
Now that we've found y let's plug it back in to solve for x.
Write down an original equation:
2x+5y=14
Substitute4foryin2x+5y=14:
2x+(5)(4)=14
2x+20=14(Simplify both sides of the equation)
2x+20+−20=14+−20(Add -20 to both sides)
2x=−6
2x
2
=
−6
2
(Divide both sides by 2)
x=−3
{y=2x
{x=-y+6
please help i have a 27 in this class please help
Answer:
x = 2
Step-by-step explanation:
y=2x so
x=-2x+6
add 2x to both sides
3x=6
divide both sides by 3
x=2
Substitute each variable to determine whether the inequality statement is true or false 16>f if f=17
Answer: The statement is false.
Step-by-step explanation:
We have the statement:
(16 > f) if f = 17
In this case:
f = 17 is the hypothesis.
16 > f is the conclusion.
Then assuming that the hypothesis is true, we need to check if the conclusion is also true.
Then:
16 > f means "16 is larger than f"
Now let's assume that the hypothesis is true, then f = 17, and we can replace this in the inequality above, now we get:
16 > 17
This says "16 is larger than 17"
This is clearly false, then when the hypothesis is true, the conclusion is false.
This means that the statement:
" 16>f if f=17 "
is false.
Turn y=1/4x+5 into standard form
Answer:
4y - x = 20
Step-by-step explanation:
Y= x/4 + 5/1
Cross multiply to get = y= (x+20/4)
4y = x+20
4y - x =20
