Answer:

m = 7, b = -2

Step-by-step explanation:

The equation y = 7x - 2 is written in y = mx + b, also known as slope intercept.

In slope-intercept, m is the slope and b is the y-intercept.

m = coefficient of x

b = constant

Similarly,

m = 7

b = -2

Hence, m = 7 and b = -2.

Step-by-step explanation:

Domain is always x. It is not a function because the y doesnt have a pattern.

Answer:

x = 0, y = 0

or

(0, 0)

Step-by-step explanation:

-24x - 36y = 0

divide the equation by 4

-8x - 9y = 0

-6x - 9y = 0

multiply the second equation by -1

6x + 9y = 0

add them together

-8x - 9y = 0

6x + 9y = 0

-2x = 0

x = 0

substitute into the second equation

-8 * 0 - 9y = 0

-9y = 0

y = 0

answer : 25%

775 / 3100 were satisfied

to make this a percentage, you need to make the demoninator 100 : 3100/100=31

and then you divide the numerator by this : 775/31= 25

Answer:

B, 4

Step-by-step explanation:

To do this you can use the Pathagaryos thereom a^2+b^2=c^2

So we have (x-2)^2+x^2=20

We can expand (x-2)^2 and get

x^2-4x+4

so we have x^2 -4x +4 + x^2=20

We can combine like terms and subtract 20 from both sides to get

2x^2-4x-16=0

We can factor this and get (2x+4)(x-4)

which means that x=4 and -2

Obviously the length can't be a negative and so we reject x= -2 and we get x=4

We can double check it and see that

(4-2)^2+4^2=20

and it does

Answer:

This is from least to greatest.

-0.89, 0.4, 1/2, 9/8, (-2)

Step-by-step explanation:

-0.89 is negative so it is the least because the other numbers are positive.

0.4 is next because 0.4 is smaller than 0.5 because 1/2 = 0.5

Then 1/2 because 9/8 is more than 1/2 of 8 which would be 4, but 9/8 is bigger than 4/8.

Finally the biggest number is (-2) Because the absolute value of -2 is 2, and 2 is a whole number, which is bigger than the decimals and fractions.

And of course 9/8 is equal to 1 1/8 but 2 is bigger than 1 1/8

Answer:

mass on day 1:  3

mass on day 2: 9

mass on day 3: 27

Step-by-step explanation:

using this equation, y = 3^x, you can plug in 1, 2, and 3 for 'x' to get the value of 'y' (which represents the mass on specific days)

3^1 = 3

3^2 = 9

3^3 = 27

Answer:

92.30

Step-by-step explanation:

The area of the banner is the amount of space on it

The approximate cost of the banner is $92.30

The dimension of the banner is given as:

Length = 9 feet

Width = 12 feet

Diagonal = 19 feet

The figure of the banner is not given.

However, the area of the banner from the complete question is 83.90

Given that the unit cost is $1.10, the total cost would be:

Total = 1.10 * 83.90

Evaluate the product

Total = 92.29

Approximate

Total = 92.30

Hence, the approximate cost of the banner is $92.30

Answer:

The asteroid will not take out Lois' penthouse.

Step-by-step explanation:

Since the distance between Clark and the base of Lois' building is x = 75 feet and the asteroid is at an angle of elevation of Ф = 62°. These two components form a right-angled triangle with opposite side h which is the height of the asteroid above the ground.

So, by trigonometric ratios,

tanФ = h/x

h = xtanФ

h = 75 ft × tan62°

h = 75 ft × 1.8807

h = 141.1 feet

Since h = height of asteroid above the ground = 141.1 feet is greater than height of the penthouse above the ground = 100 feet, the asteroid will not take out Lois' penthouse.
