Answer:
151/30
Step-by-step explanation:
if you subsitute it you will get 3 1/10
She cover more distance after rest 101.7-88.4625=13.2375
The slope form: y = mx + b
m = -3/4 therefore y = -3/4 x + b
The line passes trought the point (5/3, -7) → x = 5/3, y = -7.
Substitute the coordinates of the point to the equation:
-7 = -3/4 · 5/3 + b-
7 = -5/4 + b |+5/4
b = -28/4 + 5/4
b = -23/4
y = -3/4 x - 23/4 - the slope form
y = -3/4 x - 23/4 |· 44
y = -3x - 23 |+3x
3x + 4y = -23 - the strandard form
Answer:
no solution
Step-by-step explanation:
Suppose the system equations are:
y = (-1/4)x + 2 (1)
3y = (-3/4)x – 6 (2)
If we multiply equation (1) by 3:
3y = (-3/4)x + 6 (1)
3y = (-3/4)x – 6 (2)
then subtract it from equation (2):
0y = 0x – 12
0 = -12
This is not possible, therefore, the system equation has no solution
Answer:
Step-by-step explanation:
1. The line y=12-4x has the slope -4, then perpendicular line will have slope
The equation of this perpendicular line is
2. The vertices of the triangle are at points:
A: x=0, y=0.
B: x=0, y=12.
C:
3. The height of the triangle ABC is x-coordinate of point C, so the base of the triangle is the length of the segment AB, 12 cm.
4. The area of the triangle ABC is
