Answer:

The answer is the option A 1

Step-by-step explanation:

The options of the question are

A. 1  

B. -1  

C. -9  

D. -5

we have

m>\frac{7}{12}

The solution of this inequality is the interval------> (\frac{7}{12}, infinite)

All real numbers greater than \frac{7}{12}

Remember that

\frac{7}{12}=0.58 ------> using a calculator

so

m>0.58

we know that

If a number is a solution of the inequality

then

the number must satisfy the inequality

Verify each case

case A) m=1

substitute the value of m in the inequality and compare

1>0.58 ------> is true

therefore

the number m=1 is a solution

case B) m=-1

substitute the value of m in the inequality and compare

-1>0.58 ------> is not true

therefore

the number m=-1 is not a solution

case C) m=-9

substitute the value of m in the inequality and compare

-9>0.58 ------> is not true

therefore

the number m=-9 is not a solution

case D) m=-5

substitute the value of m in the inequality and compare

-5>0.58 ------> is not true

therefore

the number m=-5 is not a solution

Joe is trying to soup up his dragster. He knows that the time needed for the car to go from 0 to 100 miles per hour varies inver
inysia [295]
8 seconds

The hardest part of this is setting up the equation -- the calculations are pretty easy.

You're told that the time (needed to go from 0 to 100 MPH) is inversely proportional to the horsepower:  what this means is that as horsepower gets larger, time gets smaller. This makes sense since the more horsepower you have, the less time it will take you to get to 100 MPH

You can think of this as:

200 HP = 10 seconds
250 HP = x seconds

You set the equation up as:

250 HP / 200 HP = 10 sec / x sec

Now, just cross multiply and solve:

250 / 200 = 10 / x
250x = (200 x 10)
250x = 2000
x = 2000 / 250
x = 8

So, as you increase the horsepower from 200 to 250, the time decreases from 10 seconds to 8 seconds.

Hope this helps!

Good luck.

9 less than the product of 37 and x
zepelin [54]
Alrighty, so, 9 less hints to subtract. The product of 37 and x means that you're multiplying 37 and x. Therefore, I believe the answer that you're looking for is 37x-9.

Hope this helps! (:

Y = 2x^2
GarryVolchara [31]

Answer:

y = 2x^2 is a parabola opening up with it's vertex at (0,0)... y=3x^2 -4 is also a parabola opening up, but it is 'thinner' in that it rises in y faster and it's vertex is at (0,-4)

Step-by-step explanation:

all equations of the type y = ax^2 + b are parabolas centered on the y-axis, soo the vertex is always on (0,b)

If a is positive then the parabola opens up,

the bigger a is, the 'thinner' the graph is, i.e. the faster the graph rises

the value of b determines the location of the vertex, if b is added, then the vertex rises over the x-axis, if b is subtracted then the vertex is below the x-axis

Can someone help me on this math problem ?
faltersainse [42]

Answer:

4/3

Step-by-step explanation:

Given two points, we can find the slope by using

m = (y2-y1)/(x2-x1)

    = (20 - -16)/(7 - -20)

    = (20+16)/(7+20)

    = 36/27

   =4/3
