Answer:

y=-4x+2

Step-by-step explanation:

The slope intercept form is: y=mx+b

Then

y=-4x+b

y=2 and x=0 at the intercept

thus

2=-4(0)+b

b=2

y=-4x+2

Divers in a competition are scored by an international panel of judges. The highest and the lowest scores are dropped. The total

Luden [163]

Let

x--------> the degree of difficulty of the dive

we know that

1) The highest and the lowest scores are dropped

highest scores= $8.5$

lowest scores= $6.5$

the remaining scores= $[7.5, 8.0, 7.0, 7.5, 7.0]$

2) Find the total of the remaining scores

$=[7.5+8+7+7.5+7]\\ =37$

3) The total of the remaining scores is multiplied by the degree of difficulty of the dive

$37*x$

4) This product is multiplied by .6 to determine the final score

$[37*x]*0.6=77.7\\ 22.2*x=77.7\\ x=3.5$

therefore

the answer is

the degree of difficulty of the dive is $3.5$

Mr. Woo wants to ship a fishing rod that is 42 inches long to his son. He has a box with the dimensions shown.

brilliants [131]

Answer:

A. $s^2=1,700$

B. 42.4 inches. It will fit.

Step-by-step explanation:

Let s = the length of the diagonal across the bottom of the box.

$w^2+l^2\\\\10^2+40^2 = s^2\\\\100+1,600 = s^2\\\\1,700 =s^2\\\\$

Therefore, $s^2=1,700$

Let r = the length from a bottom corner to the opposite top corner.

$h^2+s^2\\\\10^2+1,700=r^2\\\\100+1,700=r^2\\\\1,800=r^2 \\\\42.4=r$

Therefore, the length of the longest tube that will fit in the box is 42.4 inches.

Since the fishing rod is only 42 inches long, which is less than 42.4 inches, by only 0.2 inches, it means it will still fit.

A bank charges $3 each time you use an out-of-network ATM. At the beginning of the month, you have $1500 in your bank account. Y

Jlenok [28]

Answer:

$y=-\frac{63}{1} x+1500$

Step-by-step explanation:

Create a table:

1500 - 63(0) = 1500

1500 - 63(1) = 1437

1500 - 63(2) = 1374

1500 - 63(3) = 1311

Turn them into ordered pair:

(0, 1500)

(1, 1437)

(2, 1374)

(3, 1311)

How do you determine if the graph opens<br> up or opens down?

strojnjashka [21]

Answer:

There is an easy way to tell whether the graph of a quadratic function opens upward or downward: if the leading coefficient is greater than zero, the parabola opens upward, and if the leading coefficient is less than zero, the parabola opens downward.
