When x = -4,
g(-4) = |-3*(-4) - 1| = 11

So, 2g(-4) = 2 * 11 = 22

[Where * represents multiplication.]

Answer:

Perimeter of rectangle:

$(4x - 14)\text{ feet}$

Step-by-step explanation:

We are given the following in the question:

Length of rectangle:

$x\text{ feet}$

Width of rectangle:

$(x-7)\text{ feet}$

Perimeter of rectangle:

$2\times \text{(Length + Width)}$

Expressions to calculate perimeter

$1. ~2((x) + (x - 7))\text{ feet}\\2.~2(2x-7)\text{ feet}\\3.~ 4x-14\text{ feet}$

The attached image shows the image of the rectangle.

Quick algebra 1 question for 10 points!

zaharov [31]

Answer:

○ $x = -7$

Step-by-step explanation:

Given the equation:

$10(x + 10) - 4 = 11 - 5(2x + 11)$ ,

to solve for $x$ , we have to rearrange the equation to make $x$ its subject.

$10(x + 10) - 4 = 11 - 5(2x + 11)$

⇒ $10x + 100 - 4 = 11 - 10x -55$ [expand brackets]

⇒ $10x + 96 = -44 - 10x$

⇒ $10x + 10x + 96 = -44$ [add $10x$ to both sides]

⇒ $20x + 96 = -44$

⇒ $20x = -44 - 96$ [subtract 96 from both sides]

⇒ $20x = -140$

⇒ $x = \frac{-140}{20}$ [divide both sides by 20]

⇒ $x = \bf-7$

Matt, the coordinator at the local emergency food hamper program, noticed the following trends: typically 200 hampers were distr

photoshop1234 [79]

Answer:

793 food hampers were distributed

Step-by-step explanation:

We need to find how many food hampers were distributed in a typical week, knowing that

200 hampers were distributed on Mondays

40 fewer hampers were distributed on Tuesdays than on Mondays, thus:

160 hampers were distributed on Tuesdays

on Wednesdays, the volume is 1.3 times Tuesday’s volume, thus 160*1.3=

208 hampers were distributed on Wednesdays

on Thursdays the number of hampers distributed was 3/4 of Monday’s volume, thus 3/4*200=

150 hampers were distributed on Thursdays

on Fridays, 50% of Thursday’s volume was distributed, therefore 50%*150=

75 hampers were distributed on Fridays

The total number of food hampers distributed in the week is

200+160+208+150+75=793

793 food hampers were distributed
