What is c in the equation 2x2-3x-4=5

1 answer:

djverab [1.8K]2 years ago

3 0

Answer:

um well if C would be the X then

Step-by-step explanation: 2 times 2 is four now you have to figure out which number minus 4 is 5 which would be nine then you go back to the 3x part and the only way to get nine from a 4-3 is it would have to be a negetive so then you see that 2 plus seven is 9 or 2- (-7) is 9 so you find three times -7 =-2.33333333

6m + 2 - 4m =<br><br><br>help with this please

devlian [24]

The answer is: 2(m+1)

First combine like terms.
<em>we do 6m-4m which is 2m</em>
2m+2=?

Second we factor. We notice that both terms have 2.
2(m+1)

<em>by distributive law, the 2 is distributed to m and 1.

Given g(x)=4-2(3-x), what is the value of g(1)

avanturin [10]

Answer:

g(1) = 0

Step-by-step explanation:

To evaluate g(1) , substitute x = 1 into g(x), that is

g(1) = 4 - 2(3 - 1)

= 4 - 2(2)

= 4 - 4

= 0

Identify an equation in point-slope form for the ine parallel to y = -2/3 x+8 that

zlopas [31]

Answer:

$y +5 = -\frac{2}{3}(x - 4)$

Step-by-step explanation:

Given

$y = -\frac{2}{3}x + 8$

Point (4,-5)

Required

Determine the line equation

From the question, we understand that the line is parallel to $y = -\frac{2}{3}x + 8$

This implies that they have the same slope, m

A linear equation is:

$y = mx + b$

Where

$m = slope$

By comparison: $y = mx + b$ and $y = -\frac{2}{3}x + 8$

$m = -\frac{2}{3}$

Next, we determine the line equation using:

$y - y_1 = m(x - x_1)$

Where

$(x_1,y_1) = (4,-5)$ and $m = -\frac{2}{3}$

$y - (-5) = -\frac{2}{3}(x - 4)$

$y +5 = -\frac{2}{3}(x - 4)$

Hence,

<em>Option C is correct</em>

Nathalie has one large bowl of popcorn. She invite 3 friends over to watch a movie. Her brother takes 1/5 of the popcorn for him

OLEGan [10]

Answer:

Each friend gets $\frac{1}{5}$ of the popcorns.

Step-by-step explanation:

Nathalie's brother takes 1/5 of the popcorn for himself.

so there is ( 1 - 1/5)

= 4/5 of the popcorns left in the bowl

including Nathalie and her 3 friends, there are (3 + 1) = 4 persons.

So, each friend gets

$\frac(4}{4 \times 5}$

= $\frac{1}{5}$

of the popcorns
