The slope intercept of a line is given by y=mx+c, where:
m=slope, c=y-intercept. 
Thus the slope-intercept form of our equation will be:
-6+2y≤42
adding 6 in both sides we get:
-6+6+2y≤42+6
2y≤6
dividing both sides by 2 we get:
(2y)/2≤6/2
y≤3
the answer is y≤3

Answer:  The required slpe-intercept form of the given inequality is

y\leq 0\times x+24.

Step-by-step explanation:  We are given to write the following inequality in the slope-intercept form :

-6+2y\leq 42~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)

We know that

the slope intercept form of a straight line with slope m and y-intercept c is given by

y=mx+c.

Writing equation (i) in slope-intercept form, we have

-6+2y\leq 42\\\\\Rightarrow 2y\leq 42+6\\\\\Rightarrow 2y\leq 48\\\\\Rightarrow y\leq 24\\\\\Rightarrow y\leq 0\times x+24,

where slope, m = 0  and  y-intercept, c = 24.

Thus, the required slpe-intercept form of the given inequality is

y\leq 0\times x+24.

Answer:

A = 1,144 ft²

Step-by-step explanation:

The base of the quadrilateral is also x.  We know this since there are 2 90° angles, there fore the other 2 angles are also 90°, making the top and bottom sides of the quadrilateral parallel to each other, and equal in measure.  

Since the entire base of the yard is 2x, the base of the triangle is x.  

The area of the triangle is

A = (1/2)bh      where b is the base, and h is the height

For this example...

A = (1/2)x(44)                  (x is the base, and 44 is the height)

So

A = (1/2)(44)x

   A = 22x

The area of the quadrilateral is

A = LW    

A = 44x

The total area of the yard is

A = 22x + 44x

  A = 66x

We are told that the entire area is 3,462. so

3,462 = 66x           now solve for 'x'

3,462/66 = x           (divide both sides by 66)

52 = x        

So the area of the picnic tables is the area of the triangle, which is

A = 22(52) = 1,144 ft²

What is the solution to this equation?<br>2х- 5+ 3x = 35​
Elena L [17]

Answer:

8

Step-by-step explanation:

3x +2x - 5 = 35 to rearrange makes it easier

then, add 3x and 2x which gives you 5x - 5 = 35

then using addition property of equality (APOE) add 5 to both sides which then cancels out the 5 on the left side of the equation and then add 5 to the right side which makes it 40. Then your equation looks like 5x = 40. then using division property of equality, divide by 5 on both sides and 40/5= 8!

While sailing, Jacob is 150 feet from a lighthouse. The angle of elevation from his feet on the boat (at sea level) to the top o
Vlada [557]

Answer:

The height of the lighthouse is approximately 166.6 feet.

Step-by-step explanation:

Let the height of the lighthouse be represented by s, then;

Tan 48° = (opposite) ÷ (adjacent)

Tan 48° = s ÷ 150

⇒ s = 150 × Tan 48°

      = 150 × 1.1106

     = 166.59

s ≅ 166.6 feet

Therefore, the height of the lighthouse is approximately 166.6 feet.

A plan traveled for a total of 2,773 miles over the course of 8 hours. Heading south, the plan traveled at an average speed of 3
AlexFokin [52]

Answer:

  5 hours

Step-by-step explanation:

Let s and w represent hours spent traveling south and west, respectively. The problem statement tells us ...

  s + w = 8 . . . . . . total trip time

  344s + 351w = 2773 . . . . total mileage (using d = s·t)

By Cramer's rule, we can find the value of s as ...

  s = (1(2773) -351(8))/(1(344) -351(1)) = -35/-7 = 5

The plane was heading south for 5 hours.

_____

<em>Comment on Cramer's rule</em>

For the equations ...

  ax +by = c

  dx +ey = f

The solution for x can be found to be ...

  x = (bf-ec)/(bd-ea)

Similarly, the solution for y is ...

  y = (cd-fa)/(bd-ea)
