1. Which equation represents a linear function?
KATRIN_1 [288]

Answer:

A, B, D are equations representing a linear function

Step-by-step explanation:

All linear functions have an equation like the following: y=mx+b, where m is the slope and b is an offset.

A. y=x-4, m=1 and b=-4

B. y=x+4, m=1 and b=4

D. y=x+7, m=1 and b=7

The third eq dont behave like a linear function since there is quadratic term on one side of the equation, this is not a linear function

Which represents the solution set to the inequality<br> -1.5(4x + 1) &gt; 4.5 -2.5(x + 1)?
laila [671]
<h2><u>The solution set to inequality is:</u></h2>

\boxed{-1.5\left(4x+1\right)>4.5-2.5\left(x+1\right)\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:x

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

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

-1.5(4x + 1) > 4.5 -2.5(x + 1)

We have to find the solution set to inequality

From given,

-1.5(4x + 1) > 4.5 -2.5(x + 1)\\\\\mathrm{Multiply\:both\:sides\:by\:}10\\\\-1.5\left(4x+1\right)\cdot \:10>4.5\cdot \:10-2.5\left(x+1\right)\cdot \:10\\\\-15\left(4x+1\right)>45-25\left(x+1\right)

Expand

-60x -15 > 45 -25x - 25\\\\Simplify\\\\-60x-15>-25x +20

\mathrm{Add\:}15\mathrm{\:to\:both\:sides}\\\\-60x-15+15>-25x+20+15\\\\Simplify\\\\-60x>-25x+35\\\\\mathrm{Add\:}25x\mathrm{\:to\:both\:sides}\\\\-60x+25x>-25x+35+25x\\\\Simplify\\\\-35x>35\\\\\mathrm{Multiply\:both\:sides\:by\:-1\:\left(reverse\:the\:inequality\right)}\\\\\left(-35x\right)\left(-1\right)

<em><u>Thus the solution set is:</u></em>

-1.5\left(4x+1\right)>4.5-2.5\left(x+1\right)\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:x

jeka57 [31]

Answer:

Ahmed needs 225g of flour to make 12 pancakes.

Step-by-step explanation:

With the information provided, you know that the recipe uses 150g of flour for 8 pancakes and you can use a rule of three to find the amount of flour needed to make 12 pancakes:

150g  →  8 pancakes

   x    ←  12 pancakes

x=(150*12)/8= 225g

According to this, the answer is that Ahmed needs 225g of flour to make 12 pancakes.

The sum of a negative number, q, and a positive integer, n, is negative. What do you know about q and n?
NISA [10]
| q | > n

1. q + n < 0
2. q + n - n < 0 - n
3. q < -n, where q is negative, and n is positive. Therefore, | q | > n.

Well, think about it. If q + n is less than zero (negative), what kind of relationship can you assume about q and n?
