Answer:

  yes

Step-by-step explanation:

When the variation is direct, the ratio of y to x is a constant (the constant of proportionality).

  19/5 = 22.8/6 = 26.6/7 = 30.4/8 = 3.8

The table is another representation of the proportional relation ...

  y = 3.8x

Yes, the variation is direct.

Answer:

x = -3 or x = 3

Step-by-step explanation:

4 - |x| = 1

Subtract 4 from both sides:

4 - 4 - |x| = 1 - 4

- |x| = -3

Divide both sides by -1:

[tex]\frac{-|x|}{-1} = \frac{-3}{-1}[/tex]

x = -3 or x = 3

Q6

answer A, as x² is the regular parabolic curve up. and x²-3 just shifts this curve down by 3 units. and that is what we need, as the extreme point of the curve is a bit below the x-axis, and therefore has a negative y value.

Q7

answer C, as this curve is the complete opposite of the curve in Q6.

it is the regular parabolic curve but down. that means -x².

but the extreme point is a bit above the x-axis (and has therefore a positive y value). -x²+3 shifts the parabolic curve up by 3 units.

Q8

answer A again. the functional values are only positive (the whole curve is above the x-axis). so, C and D are therefore wrong.

and between A and B we need to remember, that a negative exponent means 1/...

in case of B 1/(2^x).

and that would mean for large positive x we would get very small values for y.

but we see the opposite. for large x we also get large y.

so, it is 2^x (answer A).

The probability of picking an orange or a cherry flavored candy from the bag is [tex]\frac{8}{15}[/tex].

Given that, total number of candies=15, banana flavoured candies=4, strawberry flavoured candies=3, cherry flavoured candies=6 and orange flavoured candies=2.

We need to find out what would be the probability of picking an orange or a cherry-flavoured candy from the bag.

According to the probability formula, the likelihood that an event will occur is equal to the proportion of favourable outcomes to all outcomes.

The probability of an event[tex]=\frac{Number of favourable outcomes}{Total Number of outcomes}[/tex].

Now, the probability of picking an orange flavored candy from the bag [tex]=\frac{2}{15}[/tex]

The probability of picking a cherry flavored candy from the bag [tex]=\frac{6}{15}[/tex]

The probability of picking an orange or a cherry flavored candy from the bag [tex]=\frac{2}{15}+\frac{6}{15}=\frac{8}{15}[/tex].

Therefore, the probability of picking an orange or a cherry flavored candy from the bag is [tex]\frac{8}{15}[/tex].

Using implicit differentiation, it is found that the rate of change of the volume of the sphere at that instant is of 1815.84 cubic centimetres per minute.

The volume of a sphere of radius r is given by:

[tex]V = \frac{4\pi r^3}{3}[/tex]

Applying implicit differentiation, the rate of change is of:

[tex]\frac{dV}{dt} = 4\pi r^2\frac{dr}{dt}[/tex]

In this problem, we have that [tex]\frac{dr}{dt} = 0.5, r = 17[/tex], thus:

[tex]\frac{dV}{dt} = 4\pi (17)^2(0.5) = 1815.84[/tex]

The rate of change of the volume of the sphere at that instant is of 1815.84 cubic centimetres per minute.

Answer:

The slope is [tex]\frac{2}{8}[/tex]

Step-by-step explanation:

Take the general equation of a straight line [tex]y = mx+c[/tex]

Here [tex]m[/tex] is the slope of the line.

So let's get the equation of the line in the question in the same form.

[tex]-48 = 2x-8y[/tex]

Add [tex]8y[/tex] to both sides: [tex]8y - 48 = 2x[/tex]

Add [tex]48[/tex] to both sides: [tex]8y = 2x + 48[/tex]

Divide by [tex]8[/tex] to get it into the general equation: [tex]y = \frac{2}{8} x + 6[/tex]

Now compare it to the general equation to find the value of [tex]m[/tex]. The value of [tex]m[/tex] is the coefficient of [tex]x[/tex] which we can see is [tex]\frac{2}{8}[/tex]

Step-by-step explanation:

4k - 3 = 2k + 5                      Given

4k - 3 -2k = 2k + 5 - 2k         Addition (added -2k to both sides )

4k - 2k - 3 = 2k - 2k + 5        Commutative  (changed the order of the terms)

2k - 3 =  0 + 5                         Addition/ Identity

 2k - 3 = 5                               Addition

 2k - 3 + 3 = 5 + 3                 Addition (added 3 to both sides)

  2k + 0 = 8                            Addition

  2k =  8                                 Identity

The simplified expression is 7x- 2.

A mathematical operation such as subtraction, addition, multiplication, or division is used to combine terms into an expression. In a mathematical expression, the following terms are used:

Given:

−4x−2y+6 from 3x−2y+4.

So, subtraction will be as follows

3x - 2y + 4-( -4x  -2y + 6 )

or, 3x - 2y + 4  + 4x + 2y -6

or, 7x - 2

Hence, the simplified expression is 7x- 2.

Answer:

$1200

Let cost of 1 square foot be x

So, Cost of 450 square feet =  450x

We are given that A 450-square-foot apartment in New York City cost $540,000.

So, 450x = 540000

x= [tex]\frac{540000}{450}[/tex]

x= 1200

Cost of 1 square foot = $1200

Hence the price per square foot is  $1200

Answer:

Step-by-step explanation:

Noisy Music Regular Price $250 Clearance Special - 15% off

If 15% is off then we pay only 100-15 =85% from the original price.

$250 / 100 % = x / 85%

x= 250*85/100 = $ 212.5

Loud N Sharp Regular Price $200 $5 off for every $100 spent

If the price is 200 then will get $5+$5 =$10 discount

Final price will be 200-10 = $ 180

Music Mart Regular Price $300 Mail-in rebate for $115

$300-$115 = $ 185

Head Jamz Regular Price $225 Manager special – 25% off

If 25% is off we only pay 75% of the original price

$225/ 100% = x / 75%

x= 225*75/ 100 = $168.75 is the lowest price
