1 answer:

6 0

2(2x-3y=3)..................4x-6y=6..........equation 1
3(5x+2y=17) ...........15x+6y=51........equation 2

adding equation 1 and equation 2;
19x=57
x=3

2x-3y=3
(2*3)-3y=3
6-3=3y
y=1

Answer:

Step-by-step explanation:

at m=1

$\frac{10^m}{15^m}=\frac{10^1}{15^1}=\frac{10}{15}=\frac{2}{3}$

at m=0

$\frac{10^m}{15^m}=\frac{10^0}{15^0}=\frac{1}{1}=1$

both values are >= 2/3

Scientist created a scatter plot to represent the heights of four plants over time. Then, she found a line of best-fit to model

Ainat [17]

Answer:

Step-by-step explanation:

1 and 4 are growing at the same rate each day because they have the same slope, which is 3/2.

In the form y = mx+b, m is the slope, and in both 1 and 4, the slope is 3/2, meaning that they are growing at the same rate because slope = rate.

x = 27° (A)

Step-by-step explanation:

5x° + (x + 18)° = 180°

(5x + x)° + 18° = 180°

6x° + 18° = 180°

6x° = 180° - 18°

6x° = 162°

x° = 162 ÷ 6

x° = 27°

So, the value of x is 27° (A)

Hope it helpful and useful :)
