Answer:

The answer is A.

Step-by-step explanation:

Given that the total interior angles in a quadrilateral is 360°. So in order to find the 4th angle, you have to subtract the remaining angles from 360° :

θ + 120 + 100 + 75 = 360

θ  + 295 = 360

θ = 360 - 295

θ = 65

What are the ordered pairs of thesolutions for this system of equations? f(x) = x^2 – 2x + 3; f(x) = -6x
babunello [35]

First you subtract the two equations

x^2-2x+3-6x

You simplify that and get

x^2+4x+3 = 0

Now we solve using the quadratic formula.

We get x = -1 and x = -3.

Now we find the y values by plugging the x values into the equation.

f(x) is the same as y.

y = (-1)^2 - 2(-1) + 3

y = 1+2+3

y = 6

Now for the other x value.

y = (-3)^2 - 2(-3) + 3

y = 9+9

y = 18

So the two ordered pairs are (-1,6) and (-3,18)

ASHA 777 [7]

Answer:

As they triangles are congruent, we can say that, angle A = angle O

So, angle A = 105+25 =130

A = 180 - 130 = 50° all angles in a triangle add up to 180)

Soo 50° is the answer,

I'm not too sure about it but I think this is correct, hope this helps, correct me if I'm wrong....

A square patio has an area of 200 square feet. How long is each side of the patio to the nearest tenth?
Jlenok [28]
Area (square)=side²
therefore:
side²=200 feet²
side=√(200 feet²)=14.142 feet≈14.1 feet.

solution: side of square=14.1 feet.

2x-1=y,<br> 2y-4x=7 is the equation are parallel show break down
Usimov [2.4K]
Y = 2x - 1...slope here is 2 and y int is -1

2y - 4x = 7
2y = 4x + 7
y = (4/2)x + 7/2
y = 2x + 7/2...slope here is 2 and y int is 7/2

When the slopes of the lines are the same, and the y intercepts different...this means they are parallel lines
