Answer:

x = 3

Step-by-step explanation:

Given the 2 equations

x + y = 3 → (1)

2x - y = 6 → (2)

Adding the 2 equations term by term eliminates the y- term, that is

3x = 9 ( divide both sides by 3 )

x = 3

Hello!

\large\boxed{z = 75^{\circ}}

In an isosceles trapezoid, both angles on each side of the base are congruent.

∠z ≅ 75°

∠y ≅ ∠x

Because of this, we can get the angle measure for z easily:

m∠z = 75°

Which of the following lines is not parallel to the graph of y = 4x +7?
Bas_tet [7]

Answer:

  c.  4y -x = 8

Step-by-step explanation:

Each of the equations can be put into slope-intercept form (solved for y) as follows:

a: y = 4x +9

b: y = 4x -8

c: y = (1/4)x +2

d: y = 4x -4

___

The equations containing the term "4x" all describe parallel lines. The equation containing (1/4)x describes a line that intersects the given line. It is not parallel to the others.

0 A public beach in Arkansas charges non- residents $12 per day for a fishing license and $3.50 per day for live bait. Arkansas
vfiekz [6]
Non Residents:
f(x)= money in $ paid.
x=number of days.

f(x)=x(12+3.5)=15.5 x

f(x)=15.5x

Arkansas residents
f(x)=money in $ paid.
x=number of days.

f(X)=x+174

Now, we equate functions:

15.5x=x+174    (this is the equation)
15.5x-x=174
14.5x=174
x=174 / 14.5=12

Answer: the number of days is 12 days. The ecuation has one solution, because when I has solved it, I have had one solution.
