Answer:

a. 6

b. 12

c. $y = 6x + 12$

Step-by-step explanation:

a. Using two pairs of values given, (0, 12) and (1, 18)

Rate/slope = $m = \frac{y_2 - y_1}{x_2 - x_1} = \frac{18 - 12}{1 - 0} = \frac{6}{1} = 6$

Unit rate/slope (m) = 6

b. The starting value is the y-intercept (b). It is the value of of y when x = 0.

From the table, when x = 0, y = 12.

Therefore the starting value (b) would be 12.

c. The equation can be written in slope-intercept form, $y = mx + b$ , where,

m = slope/rate = 6

b = starting value/intercept = 12.

Plug in the values into the equation

The equation would be:

✅ $y = 6x + 12$

What terms govern the length of this side?The basic rule of the triangle.First side length must be less than the sum of the other two sides.So to find X we must take the largest side of the triangles and compare them with amounts from other sides.

5+x>12
8+x>20 and it's system

x>7
x>12
general solution is x>12
The least possible integral is 13.

PS: It's may be yet 12, but in this case, triangle BCD become segment.

Rick bought a car for $17,500. Each year, the car's value decreases by 20%. At this rate, what can Rick expect the value of his

Arada [10]

Answer:

His car would be worth $15,502.24

Step-by-step explanation:

20% of 17,500 is 350. 350 x 6 = 2,100. 17,500 - 2,100 = 15,400. But that is not an answer choice so be go to the closest number which is $15,502.24

Lois and Clark each ordered 3 posters that each cost x dollers. The postage for 3 posters is $5. Lois wrote an expression for th

konstantin123 [22]

The two equations are equivalent.

The postage for 3 posters is $5.
Lois$ wrote an expression for the total they both spent as 6x + 10 6(25) +10
150 +10 = 160

Clark wrote another expression for the total, saying that it represented the same cost: 2(3x + 5). = 2(3x) + 2(5) 6x + 10 = 6(25) + 10 = 150+10 160

If each poster costs $25, do the two expressions give the same amount?
