The value of the expression for t will be

t = (C - p)/m

Let p = the phone’s price in dollars

m = the cost of the selected plan in dollars per month

C = Alma’s total cost in dollars after time t, measured in months of service.

Therefore, the equation that expresses C in terms of p, m, and t will be:

C = p + m(t)

To find t will be:

C = p + m(t)

Subtract p from both sides

C - p = m(t)

Divide through by m

t = (C - p)/m

Answer:

5.6

Step-by-step explanation:

EC = 10

BC = 14

14/10 = 1.4

DE = 4

AB = x = 1.4 * 4 = 5.6

Answer:

[tex]\frac{x}{14} = \frac{4}{10}[/tex]  (set up as a proportion)

10x= 56 (cross multiply and then solve)

x= 5.6

Answer:

57.6

Step-by-step explanation:

48% is the same as 0.48

so 120 * 0.48 = 57.6

Answer:

The equation of the line perpendicular to the given line is

[tex]y=\frac 1 5 x + \frac {-13}{5}[/tex].

The equation of the line perpendicular to the given line is

[tex]y=-5 x -13[/tex].

Step-by-step explanation:

The given line is y=-5x+6

The slope of the given line, [tex]m_1=-5[/tex]

Let [tex]y= m_2 x + C_2[/tex] be the slope of the line perpendicular to y=-5x+6,

where [tex]C_2[/tex] is constant.

As multiplication of slopes of two perpendicular lines equal to -1, so

[tex]m_1m_2=-1 \\\\\Rightarrow -5\times m_2= -1 \\\\\Rightarrow m_2= \frac {-1}{-5}= \frac 1 5[/tex]

So, the equation of the line perpendicular to the given line is

[tex]y=\frac 1 5 x +C_2[/tex] which passes through the point (-2,-3), so

[tex]-3=\frac 1 5 (-2) +C_2 \\\\\Rightarrow C_2 = -3 +\frac 2 5= \frac {-13}{5}[/tex]

Hence, the equation of the line perpendicular to the given line is

[tex]y=\frac 1 5 x + \frac {-13}{5}[/tex].

Now, let [tex]y=m_3 x +C_3[/tex] be the equation of the parallel line to y=-5x+6.

As the slopes of two parallel lines are the same, so [tex]m_3=-5[/tex].

So, the equation of the parallel line becomes

[tex]y=-5 x +C_3[/tex] which passes through the point (-2,-3), so

[tex]-3=-5 (-2) +C_3 \\\\\Rightarrow C_2 = -3 - 10 = -13[/tex]

Hence, the equation of the line perpendicular to the given line is

[tex]y=-5 x -13[/tex].

Answer:

  (a), (b), (c) are non-proportional

  (d) is proportional

Step-by-step explanation:

An equation or graph with a non-zero y-intercept is non-proportional. That is true for (a), (b), (c).

The table of (d) is proportional, with a constant of proportionality of 6.5.

__

Comment on (c)

In a proportional relation, price would go up with quantity, not down. If the prices both end in 9, one cannot be double the other, as would be required for the price of a gallon to be proportional to the price of a half-gallon.

Answer:

the answer is 21

Step-by-step explanation:

21x2 = 42, 42+3 = 45

Answer: 21 cupcakes

Step-by-step explanation: x is the number of cupcakes. since she baked 45 cupcakes on tuesday, which is 3 more than 2x the number of cupcakes on monday, we would write 45=2x+3. First, subtract the 3 from both sides of the equation. This will give you 42=2x. Then divide both sides by 2. This will give you 21=x. So, the answer is 21

Answer:

2sqaured + 24

Step-by-step explanation:

Answer:

58 square units

Step-by-step explanation:

Take the shaded figure as a full larger rectangle minus the rectangular part which is not shaded.

Area of the full larger rectangle:

Area = length × width

Length = |12 - 2| = 10 units

Width = |8 - 1| = 7 units

Area = 10 × 7 = 70 units²

Area of the unshaded small rectangle:

Length = |10 - 4| = 6 units

Width = |3 - 1| = 2 units

Area = 6 × 2 = 12 units²

Area of the shaded figure = 70 - 12 = 58 square units

Answer:

The value of x depends on the amount the length is going to run to.

Step-by-step explanation:

Answer:

x = 1

Step-by-step explanation:

2x + 1 = -1

2x = -1 - 1

2x = -2

x = -2 ÷ -2

x = 1

Answer: Yes

Step-by-step explanation: You can test whether a graph is a function by checking to see if the same X value is used twice. You can also use the Vertical line test to check aswell. Research Vertical Line Test if you are clueless. But Yes, this is a function

Answer:

Median=(n+1/2)th item

Now,

4+1/2

=2.5

Again,

2nd item+(3rd - 2nd item) *0.5

40+(200-40)*0.5

40+160*0.5

40+80

120

Therefore, Median =120

round to 158.49

Answer:

(-2, 3)

Step-by-step explanation:

the point B is

B(x,y)

x

AB (A to B) is twice BC ( B to C )

AB is 2 - x. BC is x - (-4)= x + 4

So

2-x=2 (x + 4)

2-x=2x + 8

3x = -6

x = -2

y

(Same logic as above)

AB is -5 -y. BC is u - 7

-5 -y = 2(y - 7)

-5 - y = 2y - 14

3y = 9

y= 3

the point is (-2, 3)

Answer:

$2656

Step-by-step explanation:

6.25% of $10,624 is $664, so that is the amount of interest every year.

$664 times 4 is $2656, so after 4 years $2656 will have been paid.

Answer:

Multiply the second equation by -3 to get -3x - 9y = -30.

Step-by-step explanation:

When eliminating, you need to find a term with the negative of that term to combine so that they cancel each other out. An example would be 3x in the first equation and (-3x) in another equation so that when added, it becomes: 3x-3x = 0.

In the second equation, you see that there is already an x there and you just need to make it become (-3x). Thus, you multiply the entire second equation by -3 to make -3x. Once you have done that, you can combine the two equations and eliminate 3x from the first equation.

3x + 5y = 30

-3x - 9y = -30

3x + 5y -3x - 9y = 30 + (-30)

0 - 4y = 30 - 30

-4y = 0

You can find y and then x later on from here.

Answer:

t=16

Step-by-step explanation:

you have to change the numbers to get just the variable.

we start from -3.

8=t/2

(we multiply by 2 instead of dividing)

8×2=16

t=16

Answer:

The slope is -9

and the interpretation is that the percentage that drops on the battery per hour is 9%

Step-by-step explanation:

Generally, the equation of a straight line can be represented by the formula;

y = mx + b

where m is the slope and b is the y-intercept

With respect to the given equation, the slope is -9

What it means is that the percentage that drops per hour on the battery is 9%

Answer:

-9, the percentage charge that Sebastian's phone loses each hour
