Mathematics
1 answer:
Gala2k [10]3 years ago
6 0

Answer:

(x, y) = ( -4 , 4)

Step-by-step explanation:

STep 1: substitute the given value of x into the equation -7 x - 6y = 4 which will be -7 (-3 y + 8) - 6 y = 4

STEP 2: solve the equation for y so basically -7 (-3 y + 8) - 6 y will be y = 4

STEP 3:substitute the given value of x into the equation so y = 4 would be

x = -3 x 4 + 8

STEP 4: solve the equation for x.  -3 x 4 + 8 which you'd end up with x = -4

What is the slope of the line that passes through the points (10, 3) and
borishaifa [10]

Answer:

slope = 1

Step-by-step explanation:

calculate the slope m using the slope formula

m = \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

with (x₁, y₁ ) = (10, 3 ) and (x₂, y₂ ) = (7, 0 )

m = \frac{0-3}{7-10} = \frac{-3}{-3} = 1

Solve for the unknown variable "x" in the following linea equation: 2 ( 2x + 20) = 80 X =
Stella [2.4K]

Step-by-step explanation:

2(2+20)=80

4+40=80 (Distribute)

4+40-40=80-40(Subtract from both sides of the equation)

4=40(Simplify)

4/4=404/4(Divide both sides of the equation by the same term to get x=10)

=10
