5 0

If you would like to know the values of a, b, and c in the quadratic equation -2x^2 + 4x - 3 = 0, you can find this using the following steps:

ax^2 + bx + c = 0

-2x^2 + 4x - 3 = 0
a = -2
b = 4
c = -3

The correct result would be d. a = –2, b = 4, c = – 3.

Morgarella [4.7K]

Answer:

Ashley bought 6 rainbow stickers and 8 balloon stickers for her little sister.

Step-by-step explanation:

Let the number of rainbow sticker be x and number of balloon stickers be y.

Cost a single rainbow sticker= 6 cents

Cost a single balloon sticker= 4 cents

Cost a single x rainbow sticker= 6 cents × x

Cost a single y balloon sticker= 4 cents × y

Total number of stickers bought = 14

x + y =14 ..[1]

Total money spend on stickers = 68 cents

6x cents+4y cents=68 cents

$6x+4y=68$ ...[2]

Putting value of from [1] into [2];

x = 14 - y

$6(14-y)+ 4y=68$

$84-6y+4y=68$

$-2y=-16$

$y=\frac{-16}{-2}=8$

x = 14 -y =14 - 8 = 6

Write an explicit formula for an, the nth term of the sequence 21, 27, 33, ....

anygoal [31]

Answer:

Step-by-step explanation:

Remark

This is an arithmetic series. Each term differs by 6 from the previous one.

Givens

a1 = 21

d = 6

Formula

a_n = a1 + (n - 1)*d

Sample

Try it.

Let's let n = 3 which we have the answer for.

a_3 = 21 + (3-1)*6

a_3 = 21 + 2 * 6

a_3 = 21 + 12

a_3 = 33

That's exactly what the 3rd term is.

At the beginning of the month, Shiloh made 89 servings of trail mix. By the end of the month, she had 55 servings of trail mix l

schepotkina [342]

Answer:

The equation to find $x$ , the number of servings eaten during the month is:

B. $89-x=55$

Step-by-step explanation:

Given:

Number of servings of trail mix made by Shiloh = 89

Number of servings of trail mix left by the end of month = 55

To write an equation to find $x$ which is the number of servings eaten during the moth.

Solution:

The total number of servings of trail mix made = 89

Number of servings eaten during the month = $x$

Servings of trail mix left by the end of the moth can be given as:

⇒ $89-x$

Number of servings actually left by the end of the month = 55

Thus, the equation to find $x$ , the number of servings eaten during the month is:

$89-x=55$ (Answer)

On solving for $x$ we get the number of servings eaten.
