5x + 8y = -29
7x - 2y = -67 ..... multiply both sides by 4
5x + 8y = -29
28x - 8y = -268
33x + 0y = -297
x = -9
(-9, 2)
Answer:
The answer is D
Step-by-step explanation:
You use base times height
1/2bh
=1/2(2x+5)(4x)
Answer:
Option (1) will be the answer.
Step-by-step explanation:
Coordinates of the points A and B lying on the line f are (0, 2) and (2, 0) respectively.
Slope of the line f,


After dilation of line f by a scale factor of 2, coordinates of A' and B' will be,
Rule for dilation,
(x, y) → (kx, ky)
Where k = scale factor
A(0, 2) → A'(0, 4)
B(2, 0) → B'(4, 0)
Slope of line f',


Since, 
Therefore, both the lines f and f' will be parallel.
Option (1) will be the answer.
Answer:
f(x)=10+0.25x
she can put maximum 20 words
Step-by-step explanation:
f(x)<=15
10+0.25x<=15
0.25x<=5
x<=20
200 meters represents 2 cm
