Answers
Answer:
- x+2y= - 4
2y= - x - 4
Y=x-4/2
Y=x-2
Now, 2nd equation
4x+3y=5
4x+3.x-2=5
4x+3x-2=5
7x-2=5
7x=5+2
x=5+2/7
x=7/7
x=1
Now, continue with 1st equation
y=x-2
y=1-2
y=1
Therefore x=1
And
y=1

The measure of angle QPS in the cyclic quadrilateral is; 112°
What is the angle in the quadrilateral?In theorems for cyclic quadrilaterals, we know that the sum of the opposite angles of a quadrilateral in a circle is 180°, provided that the quadrilateral does not cross itself.
Now, angle QPS is opposite to 68° in the cyclic quadrilateral. This means thst;
∠QPS + 68° = 180°
∠QPS = 180 - 68
∠QPS = 112°

Sum means addition. So, you would be adding a and b. Remember this; a - b = difference, a * b = product, a ÷ b = quotient, and a + b = sum. Good luck!
Answer:
d) a+b
Step-by-step explanation:
For this question we can think of a and b as different numbers just for the sake of making the question easier. For example "a" could be 2 and "b" could be 3 (a=2 and b=3).
(However, keep in mind that "a" and "b" can be any number and that we don't know their values. But we can assign some values to them in order to solve the question more easily)
So if a=2 and b=3 in our example the notation for their sum would be 2+3. If we just put a for 2 and b for 3 we get a+b, which is the answer

Write an equation in slope
intercept form for the line
that goes through (-1, 2)
with a slope of 2.
Answers
Answer:
y = 2x + 4
Step-by-step explanation:
You already know the slope, so now you need to find the y-intercept. You need to plug in the values of x and y into the equation, y = 2x + b.
y = 2x + b
2 = 2(-1) + b
2 = -2 + b
4 = b
