(y - 6) = -4(x + 3) in slope intercept form
Answer:
y=-4x-6
Step-by-step explanation:
use the formula y=mx+b
oh btw i just posted a question so please maybe help with it???
♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️
[tex]y - 6 = - 4(x + 3)[/tex]
[tex]y - 6 = - 4x - 12[/tex]
Add sides 6
[tex]y - 6 + 6 = - 4x - 12 + 6[/tex]
[tex]y = - 4x - 6[/tex]
This is the slope-intercept form.
Done...

How do I solve 8x+5y=-20 ?
Answer: y=-8/5x-4
Step-by-step explanation:
8x+5y=-20
-8x -8x
5y=-8x-20
/5 /5
y=-8/5x-4
-5x + y = -3 and –x - 5y = - 11 by substitution
Answer:
x = 1, y = 2
Step-by-step explanation:
-5x + y = -3, we get y = 5x - 3.
Then plugs into the second equation, we get
-x - 5 (5x-3) = -11.
-x - 25x + 15 = -11,
-26x = -26
x = 1,
plugs x = 1 to y = 5x - 3, we get y = 2.
Answer:
Required Answer:--5x+y=-3---------------(1)-x-5y=-11----------------(2)From eq (1)

Solve -4b + 2 = 18.
b =
Answer:
b = -4
Step-by-step explanation:
your equation: -4b + 2 = 18
subtract 2 from both sides: -4b = 16
divide both sides by -4 to isolate the variable: b = -4
Answer:
b= -4b=18-2
=16
b=16+(-4)
=12
can anyone help i will give brainlist!! also you have to solve the equations using elimination
Step-by-step explanation:
5x+2y=29
5x-2y=41
add the equations
10x=70
divide both sides by ten
x=7
substitute 7 in the first equation
5(7)+2y=29
simplify
35+2y=29
subtract 35 from both sides
2y=-6
simplify
y=-3 x=7
3x+2y=9
5x+2y=12
subtract the equations
-2x=-3
simplify
x=1.5
substitute
3(1.5)+2y=9
simplify
4.5+2y=9
subtract 4.5 from both sides
2y=4.5
simplify
y=2.25 x=1.5
5x+2y=-9
2x-3y=4
multiply first equation by three and second by two
15x+6y=-27
4x-6y=8
add equations
19x=-19
simplify
x=-1
substitute
15(-1)+6y=-27
simplify
-15+6y=-27
add 15 to both sides
6y=-12
simplify
y=-2 x=-1

3. Which property of multiplication is shown by the equation
14.y.1 = 14y?
A. Associative
C. Commutative
B. Distributive
D. Identity
Answer:
identity

Step-by-step explanation:
Step 1. Add the fractions
One way you can solve this problem is by adding the fractions
1/4 + 1/6 + 5/12
1(3)/4(3) + 1(2)/6(2) + 5/12
3/12 + 2/12 +5/12
10/12
2. Multiply by 48
10/12 * 48( to find the amount of cupcakes)
40
3. Subtract
Now that we know the total number of cupcakes excluding the lemon is 40, we can do 48 - 40 , which is 8 cupcakes or C
Answer:
C. 8
Step-by-step explanation:
1/4 = 12
1/6 = 8
5/12 = 20
12+8+20=40
48-40 = 8
Write an equation in y = mx + b given the slope of 2 and goes through the point (4, 9).
Answer:
slope=2 ie m=2
y=2x+b
and to solve b, we put in 4 and 9 into the equation
9=2*4+b, so b=9-8=1
hence y=2x+1

Subtract 9x^2+7x-29x 2 +7x−2 from 8x-108x−10.
Answer:
20x^2 - 107x - 10.
Step-by-step explanation:
8x - 108x - 10 - (9x^2 + 7x -29x^2)

Wesley subscribes to a telecommunication company’s movie package.The plan includes a basic monthly charge of $40 and an additional charge of $1.50 for every movie ordered. 2a) Write an equation for the total charge for a month, C, in terms of the number of movies, m, Wesley orders per month. This is a required question 2b) If Wesley ordered 4 movies one month, what was his total charge for the month?
Answer:
46
Step-by-step explanation:
So, the plan
monthly =40 + 1.50x
and he orders 4 movies in a month your problem to solve now looks like this
1 month = 40+1.50x4
Then, 1 month= 40 + 6
1 month= 46

The correct answer is 26.8328157
Step-by-step explanation:
All you have to do to get this answer is you have to...
Let sqrt (x) - sqrt(y) be the square root.
6 - sqrt(20) = x + y - 2 * sqrt(xy)
So x+y = 6. And x * y = 5.
Clearly x = 5 and y = 1, as we want positive square root.
Answer = sqrt 26.8328157
