Answer:

see below

Step-by-step explanation:

$the\:x=2\:,\:x=1\:and\:the\:x=0\:are\:correct$

the mistakes are in the transision of the green lines, because a

$(-x)^2=x^2$

so the value of h(x) for 2 and 1 is equal to -2 and -1

the only thing that changes is the coordinate of x

that turns into -x

so the answers are

$(-1,-\frac{1}{4})\\\\(-2,-1)$

A word problem for 460 - 65x < 100

gtnhenbr [62]

<h3>Answer</h3>

$\sf \large \:　 \green{↬}460 - 65x < 100$

$\: \: \:$

Subtract 460 from both sides:

$\sf \large \:　 \green{↬}460 - 65x - 460 < 100 - 460$

$\: \:$

$\sf \large \:　 \green{↬} - 6x + 460 - 460 < 100 - 460$

$\: \:$

$\sf \large \:　 \green{↬} - 65x < 100 - 460$

$\: \: \:$

$\sf \large \:　 \green{↬}65x < - 360$

$\: \: \:$

Hope Helps! :)

PLEASE HELP I WILL MARK BRAINLIST BUT DONT ANSWER FOR THE POINT PLEASE I AM DESPERATE

IgorC [24]

Answer:

478.32

Step-by-step explanation:

1) the basic formula is:

$A=A_{base}+A_{sidesurface}.$

2) the Area of the base consists of 6 triangles, they are the same. In one triangle: its base is 8 cm., the height is 6.93 cm, - then the Area of one triangle is 0.5*8*6.93=27.72 (cm²);

$A_{base}=6*27.72=166.32(cm^2).$

3) the Area of the side surface consists of 6 triangles, they are the same. In one triangle: its base is 8 cm., the height is 13 cm, - then the Area of one triangle is 0.5*13*8=52 (cm.²);

$A_{sidesurface}=6*52=312(cm.^2).$

4) finally, the required Area:

$Area=A_{base}+A_{sidesurface}=166.32+312=478.32(cm.^2).$

Restaurants often slip takeout menus under Nina's apartment door. So far, Nina has collected

svp [43]

Answer:

3 indian menus

Step-by-step explanation:

If we assume that the proportions would remain the same then we can use the values provided to calculate the number of indian menus. We can use the Rule of Three in this scenario, since it is a ratio problem and we are given 3 values and a variable. We simply multiply the diagonal values and divide by the remaining value to get the variable.

20 menus <====> 4 indian menus

15 menus <====> x indian menus

(15 * 4) / 20 = x

60 / 20 = x

3 = x
