Find the slope of the line. On a coordinate plane, a line goes through (0, negative 2) and (2, negative 4). a. -1 c. -2 b. 2 d.

Sedbober [7]

Answer: Choice A) Slope = -1

==============================================

Explanation:

The two points given to us are (x1,y1) = (0,-2) and (x2,y2) = (2,-4)

Subtract the y coordinates

y2-y1 = -4-(-2) = -4+2 = -2

Subtract the x coordinates in the same order

x2-x1 = 2-0 = 2

Divide the two results to get the slope m

m = (y2-y1)/(x2-x1)

m = -2/2

m = -1

a sporting goods store offers a 40% discount on all golf clubs. Rocco spent 20% of the money in his savings account on a golf pu

Inessa05 [86]

$189

If the discounted price is $210, and his friend gets a 10% discount on that price, you can divide 210/10 and get 21.

Rocco's friend gets a $21 discount on the $210 irons, so therefore he will be paying $189

A technician compares repair costs for two types of microwave ovens (type I and type II). He believes that the repair cost for t

hoa [83]

Answer:

Since p value <0.1 accept the claim that oven I repair costs are more

Step-by-step explanation:

The data given for two types of ovens are summarised below:

Group Group One Group Two

Mean 85.7900 78.6700

SD 15.1300 17.8400

SEM 1.9533 2.3840

N 60 56

Alpha = 10%

$H_0: \mu_1 - \mu_2 =0\\H_a: \mu_1 - \mu_2> 0$

(Right tailed test)

The mean of Group One minus Group Two equals 7.1200

df = 114

standard error of difference = 3.065

t = 2.3234

p value = 0.0219

If p value <0.10 reject null hypothesis

4) Since p value <0.1 accept the claim that oven I repair costs are more

Alberto is snowboarding down a mountain with a constant slope. the slope he is on has an overall length of 1560 feet. the top of

Olenka [21]

The slope of the equation is calculated as:

$\frac{h_2-h_1}{t_2-t_1}=m$

Where $h_2$ is the height of the upper part of the slope and $h_1$ is the height of the low er part.

$m=\frac{4000-4600}{24-0}$

$m=-25$

So, the equation of the line is:

$h-4600=-25(t-0)$

$h=-25t+4600$

With this equation we can find the height of Alberto after having passed 10 sec.

$h(10)=-25 (10)+4600\\h(10)=-250+4600\\h(10)=4350$

After 10 seconds Alberto is 350 feet from the bottom of the slope.

Alberto's speed is:

$v=\frac{1560ft}{24s}=65ft/s$

The speed in miles per hour is:

$v=65ft /s*\frac{1 mile}{5280 ft}*\frac{3600s}{1 hour}\\v=44.32 miles/h$

Answer:

1 ≥ w, or w ≤ 1

Step-by-step explanation:We must solve 2/5 ≥ w -3/5. Note that w is already +, so leave it where it now is. Add 3/5 to both sides of this inequality:
