Answer:

1/3 ( 5y-2) = x

Step-by-step explanation:

5y = 3x+2

Subtract 2 from each side

5y -2 = 3x+2-2

5y-2 = 3x

Divide each side by 3

1/3 ( 5y-2) = 3x/3

1/3 ( 5y-2) = x

Answer:

10

Step-by-step explanation:

Very easy equation if you know how to do it. All you need to do is divide your total amount of something (in this case "150" as that's our amount of "money we're given") by whatever the price or amount is. (In this case 15. Each cartridge costs $15. I'm not amazing at explaining things like this.. Sorry about that. If you have any questions about this feel free to let me know!)

So to put it "all together":

150 ÷ 15 = 10.

10 is your answer.

Hope this helps and have a nice day!

Answer:

v=−1

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

−14−7(9v+3)=13v+41

−14+(−7)(9v)+(−7)(3)=13v+41(Distribute)

−14+−63v+−21=13v+41

(−63v)+(−14+−21)=13v+41(Combine Like Terms)

−63v+−35=13v+41

−63v−35=13v+41

Step 2: Subtract 13v from both sides.

−63v−35−13v=13v+41−13v

−76v−35=41

Step 3: Add 35 to both sides.

−76v−35+35=41+35

−76v=76

Step 4: Divide both sides by -76.

−76v

−76

v=−1

Answer:

v = 12.67

95% sure... I could be wrong, though.

Step-by-step explanation:

14-7(9v+3)=13v+41 ​

-14-63v-21=13v+41

-14-21=76v

6=76v

12.67=v

Answer:

25GB was used that month

Step-by-step explanation:

Here, we want to calculate the GB used for the month.

Since we have $59.99 for 20GB, then the extra that brought the bill to $75.99 must have been from the beyond charges.

The extra charges is thus $75.99 - $59.99 = $20

Now, since $4 is charged as extra and we have a total of $20, the number of extra GB is thus 20/4 = 5

So the total GB for that month is 20 + 5 = 25GB

The best modeled by a discrete graph is body temperature of an athlete during a workout.

The correct option is (D)

A discrete graph is one with scattered points. They may or may not show a direction or trend. They don't  have data in between the points already given.

A continuous graph has a line because there is data in between the points already given.

So, according to the condition the best modeled discrete graph is body temperature of an athlete during a workout.

This is because for the body temperature measure, we only need to measure it once in a while.

Answer:

y = [tex]\frac{1}{2}[/tex] x - 2

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (2, - 1) and (x₂, y₂ ) = (4, 0)

m = [tex]\frac{0+1}{4-2}[/tex] = [tex]\frac{1}{2}[/tex] , thus

y = [tex]\frac{1}{2}[/tex] x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation

Using (4, 0 ), then

0 = 2 + c ⇒ c = 0 - 2 = - 2

y = [tex]\frac{1}{2}[/tex] x - 2 ← equation of line

We want to find equations for changes of units, which allow us to change the units of a given measure to an equivalent value.

a) [tex]C = H*\frac{2c} {9h}[/tex]

b) [tex]P = H*\frac{6p}{45h}[/tex]

--------------------------------

We know two relations:

a) We want to find an equation to express the relationship between hands, h, and cubits, c.

Let's start with the relation:

9 hands = 2 cubits

we can rewrite:

[tex]1 = (2 c)/(9 h)[/tex]

Now suppose that we have a measure in hands, H.

If we multiply this measure by 1, we do not affect the measure, then we have:

[tex]H = H*1 = H*\frac{2c}{9h}[/tex]

Notice that we are dividing by hands, so we are cancelling the hands units, and we are multiplying by cubits, so we changed the units.

Then we can define C as the equivalent measure to H, such that C is in cubits.

[tex]C = H*\frac{2c}{9h}[/tex]

b) Similar to before.

Again, let's use H as a measure in hands.

With the relation:

[tex]C = H*\frac{2c}{9h}[/tex]

We change from hands to cubits.

Now with:

5 cubits = 3 paces.

We can write:

1 = 3p/5c

If we multiply our measure in cubits by the above fraction, we can change the units from cubits to paces, so we will have that P, the equivalent measure to H in paces is given by:

[tex]P = C*\frac{3p}{5c} = H*\frac{2c}{9h}*\frac{3p}{5c}= H*\frac{6p}{45h}\\\\P = H*\frac{6p}{45h}[/tex]

y = -3  x = 7

Step-by-step explanation:

2y - 3x = -27

5y + 3x = 6

3x cancels.

7y = -21

y = -3

Substitute y in 2y - 3x = -27

2(-3) - 3x = -27

-6 - 3x = -27

-3x = -21

Answer:

a. h = 60t − 4.9t²

b. 12.2 seconds

c. 183.7 meters

Step-by-step explanation:

a. Given:

y₀ = 0 m

v₀ = 60 m/s

a = -9.8 m/s²

y = y₀ + v₀ t + ½ at²

h = 0 m + (60 m/s) t + ½ (-9.8 m/s²) t²

h = 60t − 4.9t²

b. When the ball lands, h = 0.

0 = 60t − 4.9t²

0 = t (60 − 4.9t)

t = 0 or 12.2

The ball lands after 12.2 seconds.

c. The maximum height is at the vertex of the parabola.

t = -b / (2a)

t = -60 / (2 × -4.9)

t = 6.1 seconds

Alternatively, the maximum height is reached at half the time it takes to land.

t = 12.2 / 2

t = 6.1 seconds

After 6.1 seconds, the height reached is:

h = 60 (6.1) − 4.9 (6.1)²

h = 183.7 meters
