Answer:

h < -3

Step-by-step explanation:

2 < -19 - 7h

2 + 19 < -7h

21 < - 7h

21/7 < -h

bringing -h to the left

-h > 3

changing the sign to positive h

h < -3

solution set : {h < -3}

Hope that helps...

Answer:

h < -3

Step-by-step explanation:

2 < -19 -7h

or 19 + 2 < -7h

or 21 < -7h

or 21/(-7) > h [flip the sign when dividing with negative Number ]

∴ -3 > h ( h < -3 )

hoping that this will help you

X is directly proportional to y.work out the missing values,p and q, in the table
Katena32 [7]

Answer:

p = 21, and q = 30

Step-by-step explanation:

If x is directly proportional to y, then we know:

y = 35x / 60

We can factor 5 out of that, giving us:

y = 7x / 12

We can also find the inverse of that relationship:

y = 7x / 12

12y = 7x

x = 12y / 7

So in the second row, where x = 36:

y = 7 × 36 / 12

y = 7 × 3

y = 21

And in the third row where y = 17.5:

x = 12 × 17.5 / 7

x = 210 / 7

x = 30

So p = 21, and q = 30

Evaluate.
aleksandrvk [35]

Answer: -2 4/15

Step-by-step explanation: To properly subtract, we need to find a common denominator. We can list the multiples of 3 and 5 to find the common denominator:

3: 3, 6, 9, 12, 15

5: 5, 10, 15


The first common multiple we see is 15.

Calculation:

3 · 3 = 9

9 + 1 = 10

3 1/3 = 10/3

5 x 5 = 25

25 + 3 = 28

-5 3/5 = -28/5

Now to convert into fifteen as the denominator:

-28/5 = -28 x 3/5 x 3 = -84/15

10/3 = 10 x 5/3 x 5 = 50/15

Now to subtract accordingly:

50/15 - 84/15 = -34/15

Final answer: -34/15 (can be reduced to -2 4/15).

Graph a line through the origin that has a slope of -4/3
Schach [20]

Answer:

The line goes the through the origin

The line is sloping upward

The x-intercept is 0

Step-by-step explanation:

step 1

Find the equation of the line in point slope form

we have

substitute

step 2

Convert to slope intercept form

isolate the variable y

Applying the distributive property right side

The line represent a direct variation (the line passes though the origin)

step 3

Verify each statement

case a) The line is horizontal

The statement is false

Because a horizontal line has a slope equal to zero and this line has slope equal to m=3/4

case b) The line goes the through the origin

The statement is true

Because the line represent a direct variation

case c) The point (3,4) lies on the line

The statement is false

Because the ordered pair not satisfy the equation

Verify

For x=3, y=4

substitute in the equation

----> is not true

so

the ordered pair not satisfy the equation

therefore

The ordered pair not lies on the line

case d) The line is sloping upward

The statement is true

Because the slope is positive (is an increasing function)

case e) The x-intercept is 0

The statement is true

Because in a proportional relationship the x-intercept and the y-intercept are equal to zero
