Answer:
for number 5 Subtract 18 from both sides of the equation
4+18−18=30−18
for number 1 Subtract 7 from both sides of the equation
so number 3 subtract 3 from each side and so on hope it helps
im not sure how to explain it but--
for example.. the first one
1) y + 7 = 12
first, you subtract 7 from both sides
so-- you'll subtract 7-7 on the left and 12-7 from the right
now, you have y by itself since 7-7 = 0
y = 12-7, or y = 5
also its important to note that when the equation is like 2) and uses subtraction (x-4) instead of addition (y +7)-- then you add to both sides
so for 2)-- you'd add 4 to both sides for 4 to cancel out to equal 0
your goal is always to isolate the variable on one side

Answer:
Y is the midpoint of XZ, so XY = YZ
20x - 30 = 12x + 1020x - 12x = 10 + 308x = 40x = 5Find XZ:
XZ = 2(XY) = 2(20*5 - 30) = 140The answer is:
x = 5 and XZ = 140------------------------
B is the midpoint of AC, so AB = BC
4x + 3 = 2x + 154x - 2x = 15 - 32x = 12x = 6Find AC:
AC = 2(AB) = 2(4*6 + 3) = 54The answer is:
x = 6, AC = 54!50 POINTS!

does the point (4,-2) lie on the circle with a center at (4,0) and a radius of 2?
Answers
Answer:
Yes
Step-by-step explanation:
It lies on the circle because the radius is 2 and the point goes down two units just like the radius
Answer:
yes
Step-by-step explanation:
the radius extends out 2 points throughout the entire circle therefore -2 will be reached as it is 2 units below the center of (4, 0)

Write the equation of a line parallel to the line y = 4x - 3 and passing through the point (0,10).
Answers
Answer:
y=4x + 10
Step-by-step explanation:
Parallel lines always have the same slope. The point that you have is the y-intercept because the x is 0. So now you have both the slope and y- intercept and just need to sub it into the y=mx+b equation
The equation of line passes through the point (0, 10) will be;
⇒ y = 4x + 10
What is Equation of line?The equation of line in point-slope form passing through the points
(x₁ , y₁) and (x₂, y₂) with slope m is defined as;
⇒ y - y₁ = m (x - x₁)
Where, m = (y₂ - y₁) / (x₂ - x₁)
Given that;
The point on the line are (0, 10).
And, The parallel line is,
⇒ y = 4x - 3
Now,
Since, The equation of line passes through the point (0, 10).
So, We need to find the slope of the line.
Since, The slope of the parallel line is same.
Hence, Slope of the line is,
y = 4x - 3
m = dy/dx = 4
m = 4
Thus, The equation of line with slope 4 is,
⇒ y - 10 = 4 (x - 0)
⇒ y - 10 = 4x
⇒ y = 4x + 10
Therefore, The equation of line passes through the point (0, 10) will be;
⇒ y = 4x + 10
