Write the equation -11x+9y=-12 in slope intercept form. what are the slope and y intercept?
Answer:
Step-by-step explanation:
first solve for y (or x) I chose y.
-11 + 9y = -12
(-11) - (-12) = 1
9y = 1
9/1 = 1
y=1, now for x.
-11x + 9 = -12
-12 - 9 = -21
-11x = -21
-21/-11 = -32
x = -32.

Answer:
6. 2
7. (-3/2)
Step-by-step explanation:
6. 4x - 2y = 8
-4x -4x
-2y = -4x + 8
y = 2x + 4
y = 2/3x + 1
reciprocal of 2/3 is -3/2
Answer:
see explanation
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
(6)
Given
4x - 2y = 8 ( subtract 4x from both sides )
- 2y = - 4x + 8 ( divide all 3 terms by - 2 )
y = 2x - 4 ← in slope- intercept form
with slope m = 2
Parallel lines have equal slopes, thus
Slope of parallel line is m = 2
----------------------------------------------------------
(7)
Given
y = [tex]\frac{2}{3}[/tex] x + 1 ← in slope- intercept form
with slope m = [tex]\frac{2}{3}[/tex]
Given a line with slope m then the slope of a line perpendicular to it is
[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{\frac{2}{3} }[/tex] = - [tex]\frac{3}{2}[/tex]

Two unidentified flying discs are detected by a receiver. The angle of elevation from the receiver to each disc is 39.48 degree. The discs are hovering at a direct distance of 826m and 1.296km from the receiver. Find the difference in height between the two unidentified flying discs, to the nearest meter.
Answer:
The answer is "298.83 m"
Step-by-step explanation:
Its gap from its transmitter from each disc comprises of 2 triangles. Its horizontal segment via disc to vertical, and longitudinal segment. Disk height, h, is parallel to a horizontal disc Wink including its line across recipient to disc or horizontal 39. 48^{\circ}
[tex]\to 39. 48^{\circ} = \frac{h_1}{826 \ m}\\\\ \to 826\ m (\ sin 39. 48^{\circ} ) = h_1\\\\ \to 525.18 = h_1\\\\[/tex]
if:
[tex]\to \sin 39. 48^{\circ} = \frac{h_2}{1.296 \ km}\\\\ \to \sin 39. 48^{\circ} (1296 \ m) = h_2\\\\ \to 824.01 = h_2\\\\\to h_2 - h_1 = 824.01 - 525.18\\\\[/tex]
[tex]= 298.83 \ m[/tex]
Identify h (x) = [x] + 4
A.
direct variation function
B.
constant function
C.
absolute value function
D.
greatest integer function
Answer:A- direct variation function
Step-by-step explanation:
h(x) = [x] + 4 is in A. direct variation function as we increase the value of x the function h(x) will also increase and vice versa.
What is proportion?Proportions are of two types one is the direct proportion in which if one quantity is increased by a constant k the other quantity will also be increased by the same constant k and vice versa.
In the case of inverse proportion if one quantity is increased by a constant k the quantity will decrease by the same constant k and vice versa.
Given, h(x) = [x] + 4, as we increase the value of x the function h(x) will also increase and vice versa.
So, h(x) = [x] + 4 is in direct variation.
