You can clear the zeros in the equation from the exponents. after you factor it should be

${- 3}^{2} \times { - 4}^{2} \times 5 \\ 9 \times 16 \times 5 \\ 45 \times 16 \\ 720$

A linear function has a slope of

Reil [10]

Corrected Question

A linear function has a slope of $-\dfrac{7}{9}$ and a y-intercept of 3. How does this function compare to the linear function that is represented by the equation $y+11=-\dfrac{7}{9}(x-18)$ ?

Answer:

(A)It has the same slope and the same y-intercept.

Step-by-step explanation:

First linear function

Slope = $-\dfrac{7}{9}$

y-intercept =3

Second Linear function

$y+11=-\dfrac{7}{9}(x-18)\\y=-\dfrac{7}{9}(x-18)-11\\y=-\dfrac{7}{9}x+(-\dfrac{7}{9})(-18)-11\\y=-\dfrac{7}{9}x+14-11\\y=-\dfrac{7}{9}x+3$

Comparing with the slope-intercept form y=mx+c

Slope = $-\dfrac{7}{9}$

y-intercept =3

Therefore, the two functions has the same slope and the same y-intercept.

The correct option is A

One of the measures of a triangle is 30º. If the sum of the other 2 angles is 150º and the differnce their measures is 18º what

Rasek [7]

Answer: 84° & 66°

Step-by-step explanation:

find our variables...

difference in two unknown angles is 18 so...

Let's use a, b, & c to set up

a=30 b=b c=b-18

150=b+c

150=b+(b-18)

150=2b-18

168=2b

84=b

Use our known b to find c...

c=b-18

c=84-18

c=66

Adding all three up to make sure they give us 180 degrees is a good way to check our work.

a+b+c=

30+84+66=180

What is the equation of the line in slope-intercept form with slope -3/2 and y-intercept -5?

V125BC [204]

About Slope Intercept Form:

y = mx + b
m represents the slope
b represents the y-intercept or AKA the starting point

ABOUT PROBLEM:

Since -3/2 is the slope, it represents m in Slope Intercept Form
Since -5 is the y-intercept, it represents b in Slope Intrecept Form

y = mx + b

y = -3/2x + -5 --- IN Slope Intercept Form

Hope this helps you!!! :)

If you had a choice between playing golf or going to the movies and you chose to go to the movies, what is the opportunity cost

Mice21 [21]

The potential gain that could have come with golfing

Step-by-step explanation:

Opportunity cost is the loss of something you could have gotten from the choice you didn't go with. so I'm this case, the opportunity cost of chosing the movies is what you missed out on by not going golfing.

Which statement is correct? StartFraction 1 inch Over 2.54 centimeters EndFraction = StartFraction 7 inches Over 17.68 centimete

Bond [772]

Answer:

1 yard / 36 inches = 7 yards / 252 inches

Step-by-step explanation:

1 inch / 2.54cm = 7 inch/ 17.68 cm

1 foot / 12 inches = 7 feet / 74 inches

1 yard / 36 inches = 7 yards / 252 inches

1 meter / 3.28 feets = 7 meters / 22.86 feets

To establish the correctness of the statements above , we express the fractions in decimals and see if the right hand side = left hand side

1 inch / 2.54cm = 7 inch/ 17.68 cm

0.3937007 = 0.3959276 (incorrect)

1 foot / 12 inches = 7 feet / 74 inches

0.0833333 = 0.0945945 (incorrect)

1 yard / 36 inches = 7 yards / 252 inches

0.0277777 = 0.0277777 (correct)

1 meter / 3.28 feets = 7 meters / 22.86 feets

0.3048780 = 0.3062117 (incorrect)
