No solutions because once you combine like terms, you end up with 6=7 which is a false statement. (-3a and +3a cancel out)

No solution because -3a +3a is cancelled out and 6 does not equal 7

Write the slip-intercept form of the equation of the line described
kompoz [17]

Answer:

1) y=⅚x -2⅓

2) y=8/3x -5

Step-by-step explanation:

<u>Point-slope form:</u>

y=mx+c, where m is the gradient and c is the y-intercept.

Parallel lines have the same gradient.

Gradient of given line= \frac{5}{6}

Thus, m=⅚

Susbt. m=⅚ into the equation,

y= ⅚x +c

Since the line passes through the point (4, 1), (4, 1) must satisfy the equation. Thus, substitute (4, 1) into the equation to find c.

When x=4, y=1,

1= ⅚(4) +c

1 =  \frac{20}{6}  + c \\ c = 1 -  \frac{20}{6}  \\ c = 1 - 3 \frac{1}{3}  \\ c =  - 2 \frac{1}{3}

Thus the equation of the line is y =  \frac{5}{6} x - 2 \frac{1}{3}.

The gradients of perpendicular lines= -1.

Gradient of given line= -⅜

-⅜(gradient of line)= -1

gradient of line

= -1 ÷ (-⅜)

= -1 ×(-8/3)

= \frac{8}{3}

y =  \frac{8}{3} x + c

When x=3, y=3,

3 =  \frac{8}{3} (3) + c \\ 3 = 8 + c \\ c = 3 - 8 \\ c =  - 5

Thus the equation of the line is y =  \frac{8}{3} x - 5.

A truck can travel 80 miles in the same time that ot takes a car to travel 90 miles. If the truck’s rate is 5 miles per hour slo
SIZIF [17.4K]
The truck was going 40 miles per hour

The amount of time was 2 hours:
(90-80: 10)(10/2=5)

80 divided by two is 40


The car was going 45 miles per hour


(90-80:10)(10/2=5)

90 divided by two is 45

Recall that rational numbers are numbers that can be represented as the ratio, or fraction, of two integers. When expressed as d
Alenkasestr [34]

Answer:

1)  \frac{5}{-14}=0.3571428571 2) Terminating

Step-by-step explanation:

1st. To answer this question let's divide with long division algorithm  5 and -14.

  <u> 0.3571428571</u>

-14)50

    42

     ---

     80

     -70

      --

    100

      98

      ---

     20

     14

    ----

      60

      -56

       ---

      40

       28

      --

     120

    -112

     ----

       80

       70

       --

      100

       -98

      --  

       2

5 (dividend) : -14 (divisor) \frac{5}{-14}

Long division (check below)

With the same two numbers -14 and 5 we can write in a Long Division

 

5) -14

<u>   - 2.8</u>

5) -14

    10

   40

So \frac{-14}{5}=-2.8

2nd. Both are terminating ones for they have finite quantities of numbers. -2.8 and 0.3571428571, as we can see that these are rational numbers for they can be written as a/b, and b≠ 0.

\frac{5}{-14} form.

\frac{-14}{5} form.
