i took the k12 quiz
can anyone help please im havinga prblem in this thank u
Yeah Bro ! I'm here ,
.Given that ;-
slope ( m) = 3/2
y-intercept (c) = -3
Now ,
we know the equation of straight line in slope intercept form;
I.e
y = mx+c
Just substitute m and c 's value , we get
y= (3/2)x +( -3)
or,. y = 3x/2 - 3
[tex]y = \frac{3x}{2} - 3 \\ y = \frac{3x - 6}{2} \\ 2y = 3x - 6 \\ 3x - 2y = 6\\ [/tex]
,
Hence 3x-2y = .6
3x-2y-6 =0 is the required equation.

Start with a unlock code of 100. For each of the following statements that is true, add 10 TIMES its statement number to the unlock code. Enter your final number to unlock the door
1. 1/2 + 3/4=3/4
2. 5/8 - 1/4 = 3/8
3. 4/5 + 7/10 = 1 1/2
4. 2 1/2 - 1 5/6 =1/6
1/2 + 3/4 = 3/4 ........... false, so we do not add anything
5/8 - 1/4 = 3/8 ............ true, so we have (10 * 3/8) = 15/4
4/5 + 7/10 = 1 1/2 ....... true, so we have (10 * 1 1/2) = 15
2 1/2 - 1 5/6 = 1/6 ...... false, so we do not add anything.
we are then left with 15/4 and 15, on adding all together, we have
100 + 15/4 + 15 = 118.75

y=mx+b
m is the slope
b is the y intercept
y=1/3x+4
1/3 = slope
4 = y intercept
Making the answer 1/3.
What is the inverse of h(x)=3 square root x -3
Answer:
y = [tex]\frac{x^{2} + 27}{8}[/tex]
Step-by-step explanation:
To find the inverse, we will set it equal to y, switch the x and y values, then solve for y.
[Given] h(x)=3 square root x -3
[Rewrite] y = 3 [tex]\sqrt{x-3}[/tex]
[Switch values] x = 3 [tex]\sqrt{y-3}[/tex]
[Square both sides] x² = 9(y - 3)
[Distrubte] x² = 8y - 27
[Add 27 to both sides & flip equation] 8y = x² + 27
[Divide both sides of 8] y = [tex]\frac{x^{2} + 27}{8}[/tex]

GEOMETRY For what values of r will the area of the shaded region be greater than or equal to 12 square units? Write your answer as an
inequality
Answer:
Step-by-step explanation:
Find the area of the shaded region in terms of r.
1. The area of the circle with radius r is
2. The area of the square with diagonal 2r is
3. The area of the shaded region is the difference
Since the area of the shaded region must be greater or equal to then
This inequality is solved only in positive numbers, because r cannot be negative.

Name the
alternate
interior angle
with angle 5.
==================================
Explanation:
We can think of lines L and M as sort of train tracks. Inside the train tracks we have the interior angles of: 3, 4, 5, 6
Angles 3 and 6 are one pair of alternate interior angles. They are on alternate sides of the transversal line N.
The other pair of alternate interior angles are 4 and 5
Alternate interior angles are only congruent when L and M are parallel.
Answer:
Angle 4
Step-by-step explanation:
I believe it's on the opposite side of the transversal so yee
Describe of 45 angle
Answer: A 45-degree angle is exactly half of a 90-degree angle formed between two rays. It is an acute angle and two angles measuring 45 degrees from a right angle or a 90-degree angle. We know that an angle is formed when two rays meet at a vertex.

Answer:
x2 y-32
Step-by-step explanation:
Answer:
[tex]y=224-16x[/tex]
Step-by-step explanation:
Stare at the table for a bit. if you look at the y you can tell that the difference between two rows is the same, and it's equal to 32: every time x increases by 2, y decreases by 32; it means that if x increased by 1, y would decrease by 16. At this point we can write the equation as [tex]y=q-16x[/tex] To find q there are 2 ways: one is to plug the value from any line in place of y and x, or, more elegant, is to backtrack the table: if y goes down by 32 when x raises by 2, it emans that if x decreases by 2, y will go up by 32. And 192+32 is 224, our q value.
