The value of a baseball card can be represented by the equation y=3x+39,where x represents the number of years that Robert has owned the card and y represents the total value,in dollars,of the card.What was the value of the card when Robert originally purchased it?

Answer:

Y = 1

Step-by-step explanation:

on a graph this would be a circular shape and y= 1

you convert decimals to fractions by how much more numbers are after the point the more 0Answer:

for example 0.2=2/10  and0.25= 25/100

and if a zero is infront of the number like this 0.02 then it will be the same except it will be 2/100

Step-by-step explanation:

Answer: s = j + 18

Step-by-step explanation:

Let's say Steve's money can be represented as s, and Joe's money as j.  Because Steve has 18 more dollars than Joe, simply add 18 to Joe's money to solve for s.

Hope it helps :) and let me know if you want me to elaborate.

Answer:  See below.

Step-by-step explanation:

(3/2)*(3/4) = 9/8

9/8, or 1 1/8 is greater than 3/4

The factor (3/2) is misleading.  It is 1.5 written as a fraction and its appearance as a fraction makes one think it is a small number.  

Answer:

90−74=16∘.

Step-by-step explanation:

Answer:

The first term of the sequence is -8.95 with a common difference of 2.1.

The sequence is:

-8.95, -6.85, -4.75, -2.65...

Step-by-step explanation:

We are given that the sum of the first ten terms of a linear sequence is 5, and the sum of the next ten terms is 215.

And we want to find the sequence.

Recall that the sum of an A.P. is given by:

S = k / 2 ( a + xk)

Where a is the first term, k is the number of terms, and x_k is the last term.

We can represent our term values with the direct formula:

Xn = a + d (n-1)

Where the first term, x₁ = a.

The sum of the first ten terms is 5. Hence, S = 5, k = 10, a = x₁ and x_k = x₁₀:

(5) = 10/2 (a+xk)

5 = 5(a+(a+9d))

2a + 9d = 1

The sum of the next ten terms (that is, from x₁₁ to x₂₀) is 215. Hence, S = 215 when k = 10, a = x₁₁, and x_k = x₂₀:

(215) = (10)/2 (a + xk)

215 = 5((a+d(11-1))+(a+d(20-1)))

2a + 29d = 43

This yields a system of equations:

[tex]\left \{ {{2a+9d=1} \atop {2a+29d=43}} \right.[/tex]

Solve:

(2a + 9d) + (-2a - 29d) = (1) + (-43)

-20d = -42

d = 2.1

Consequently:

a = 1/2(1-9d)

= 1/2(1-9(2.1))

= -8.95

In conclusion, the first term of the sequence is -8.95 with a common difference of 2.1.

The sequence is:

-8.95, -6.85, -4.75, -2.65...  

Answer:

20

Step-by-step explanation:

first, find out how much money you already made:

78 x 3 = 234

then, find out how much more you need to make:

350-234=116

divide the price of candy baskets by the amount of money left y out need to make:

116/6=19.3

round becauee you can’t sell .3 of a basket

19.3 rounds to 20

Answer:

Density is directly related to the mass and the volume. In fact, it tells us of the exact relationship between the two. To find an object's density, we take its mass and divide it by its volume. If the mass has a large volume, but a small mass it would be said to have a low density.

Answer:

210

Step-by-step explanation:

25% can also be written as .25. If you multiply .25 by 280 you get 70. 70 is 25% of 280. If you take 70 from 280 you get 210.

Answer:

y=3-2x

Step-by-step explanation:

Parallel to y = 3 − 2 x => y=c-2x

Through (3,1) => 1=c-2(1) <=> c=3

Line is y=3-2x

Answer:

a = 2; b = 1 and c =3

Step-by-step explanation:

2(q +p) = 1 + 5q

2q + 2p = 1 + 5q

2p = 1 + 3q

2p - 1 = 3q

[tex]\frac{2p -1}{3} = q[/tex]

Answer:

x = Infinite answers.

y = Infinite answers.

Step-by-step explanation:

x + y = 3

2x + 2y = 6

2x + 2y = 6

2x + 2y = 6

=> Therefore, x and y have infinite values that can fit the equation.
