y= -6x + 1/2
PLEASE I NEED THE ANSWER AND EXPLANATION
Answer:
m = -6 (slope)
b = (1/2)
The Y posistion is (0, 0.5) and the slope of the graph is -6/1 (down 6, right 1).
Some examples of where the line is could be:
(1, -5.5)
(-1, 6.5)

When graphing an inequality, the boundary line needs to be graphed first. Which graph correctly shows the boundary line of the inequality?
y <1/3x+ 1
Answer:
C (Top Right)
Step-by-step explanation:
First things first, the line is dotted which makes it one of the answers since it's less than, instead of equal to or less than. Both numbers are positive, the bottom left graph goes into the -x while the top right graph keeps the slope increasing positively by 1/3 + 1.
The boundary line of the inequality y <1/3x+ 1 is represented by the graph C.
Let us find two points on the line.
You can choose any x-values you like and calculate the corresponding y-values using the equation.
When x=0 then y=1.
When x=3, then y=2
Now let us find the graph in which the line passes through (0, 1) and (3, 2).
The boundary line should be dotted because it is less than and doesnot have equal symbol.
When we observe these two criteria's the graph C is the graph for inequality y <1/3x+ 1.
Hence, Graph c correctly shows the boundary line of the inequality y <1/3x+ 1.

The size of a television is the length of the diagonal of its screen in inches. The
aspect ratio of the screens of older televisions is 4:3, while the aspect ratio of
newer wide-screen televisions is 16:9. Find the width and height of an older 20-
inch television whose screen has an aspect ratio of 4:3. Show all work to receive
credit.
Answer:
Step-by-step explanation:
(3x)² + (4x)² = 20²
9x² + 16x² = 400
25x² = 400
x² = 16
x = 4
height = 3(4) = 12 inches
width = 4(4) = 16 inches
Quadrilateral ABCD has the following angle measures. Find the Measure of angle A.
B: 59°
C: 103°
D: 100°
Answer:
∠A = 98
Step-by-step explanation:
total sum of angles in a quadrilateral is 360
∠A + ∠B + ∠C +∠D = 360
∠A + 59 + 103 + 100 = 360
∠A + 262 = 360
∠A = 360- 262
∠A = 98

Find Y if f(x)=g(x),please help me to answer this problem.
If f(x) = g(x)
Then :
(x-4)/(x²+1) = (x² - 4) / (x²+ 1)
We can simplify on both sides by x² + 1 :
x - 4 = x² - 4
x = x²
x - x² = 0
x(1-x) = 0
So either x = 0, or x = 1
S = {0,1}

What is the value of x if a slope is 2, and a line passing through (x, 3) and (1,5).
Answer:
x = 0
Step-by-step explanation:
Slope = change in y/change in x
Slope = 5-3/1-x
2 = 2/1-x
2(1 - x) = 2
2 - 2x = 2
2 = 2 - 2x
0 = -2x
x = 0

A triangle has an angle that measures 60°. The other two angles are in a ratio of 3:5. What are the measures of those two angles?
Answer:
180
Step-by-step explanation:
all 3 angles of all triangles sum to 180
if one angle = 60, the other two angles sum to 120
a 3:5 ratio means one angle is 3/8 of 120 and the other is 5/8 of 120
3/8 times 120 = 3(120)/8 = 3(15)= 45 degrees
5/8 times 120 = 5(120)/8 = 5(15) = 75 degrees
45+75 = 120
120+60 = 180 degrees = sum of all 3 angles
