Answer:

-3

Step-by-step explanation:

Please write this as  f(x) = x^2 + 4x - 12.  "x^2" represents "the square of x."

f(2) is the value of this function when x = 2:

f(2) =  f(2) = (2)^2 + 4(2) - 12  =  9 - 12 = -3

A science class has a ratio of 3 boys and 2 girls. Can there be 24 students in the class?
guajiro [1.7K]

Answer:

Let 3x be the number of boys

Let 2x be the number of girls

3x + 2x = 24

5x = 24

x = 4.8

3(4.8) = 14.4 boys

2(4.8) = 9.6 girls

There can't be 24 students for a ratio of 3 boys and 2 girls, because there can't be 14.4 boys and 9.6 girls, it has to be an exact number, otherwise it wouldn't make any sense.

For example, you and I are both 1 person, we can't be half a person or 0.6 of a person, only 1.

Two students were given the expression shown to simplify.
navik [9.2K]
<h3>The equivalent expression is 6 + 6x</h3>

<em><u>Solution:</u></em>

<em><u>Given expression is:</u></em>

9 - (3 - 6x)

We have to find the equivalent expression

Use the distributive property,

a(b + c) = ab + bc

Therefore, from given expression,

9 - 1(3 - 6x) = 9 - 3 + 6x

Combine the constants, 9 - 3 = 6

9 - 1(3 - 6x) = 6 + 6x

Thus the equivalent expression is 6 + 6x

Can someone help please?
Alekssandra [29.7K]

Answer:

y=1X

Step-by-step explanation:

This is because the distance over the money made over the days worked is 2/2 which simplifies to 1 so that would be the one x. then the y intercept is found on the y axis where does the line cross the y axis? this would be at zero so you do not need to put that in the equation

Can u guys PLEASE answer question 26 and 27. THIS IS URGENT
Nadya [2.5K]

Step-by-step explanation:

(26)  \\ \frac{m}{3} - 4 \geqslant  \frac{m - 2}{4}   \\  \\  \therefore \: \frac{m - 12}{3} \geqslant  \frac{m - 2}{4}   \\  \\ \therefore \:\frac{4(m - 12)}{12} \geqslant  \frac{3(m - 2)}{12}    \\  \\ \therefore \:4m - 48 \geqslant 3m - 6 \\  \\ \therefore \:4m - 3m \geqslant 48 - 6 \\  \\  \huge \red{ \boxed{\therefore \:m \geqslant 42}} \\  \\ (27) \\  \frac{a}{2}  -  \frac{a - 3}{3}  < 5 -  \frac{a}{6}  \\  \\ \therefore \: \frac{3a - 2a + 6}{6}  <  \frac{30 - a}{6}  \\  \\ \therefore \: \frac{a + 6}{6}  <  \frac{30 - a}{6} \\  \\ \therefore \: a + 6 < 30 - a \\  \\ \therefore \: a + a < 30 - 6 \\  \\ \therefore \: 2 a < 24 \\  \\ \therefore \:  a <  \frac{24}{2}  \\  \\  \huge \orange{ \boxed{\therefore \:  a <  12}}
