Step-by-step explanation:
7x+5y=25 ×3 7×-1.5+5y=25
5x+3y= -23 ×5 -10.5 +5y =25
5y= 25 + 10.5
21x+15y=75 5y= 35.5
25x+15y=69 y= 7.1
-4x=6
x=-1.5
Answer: The equation in slope intercept form is
y = 2x/5 + 4/5
Step-by-step explanation:
The equation of a straight line can be represented in the slope-intercept form, y = mx + c
Where c = y intercept
m represents the slope of the line.
The given equation is expressed as
2x - 5y + 4 = 0
Adding 5y to the left hand side and the right hand side of the equation, it becomes,
2x - 5y + 5y + 4 = 5y
5y = 2x + 4
Dividing the left hand side and the right hand side of the equation by 5, it becomes,
5y/5 = 2x/5 + 4/5
y = 2x/5 + 4/5

Answer:
444.6
Step-by-step explanation:
first find the area of the triangle: (9*7.6)/2 = 34.2
now multiply by depth: 34.2 * 13 = 444.6
volume of the figure = 444.6
Answer:
B. m<3 = 100°
C. m<2 + m<4 = 80°
Step-by-step explanation:
Given that n is parallel to m, the following are the measure of each numbered angles:
m<1 = 60° (vertical angles are congruent)
m<2 = 20° (corresponding angles are congruent)
m<3 = 180 - (m<CAB + m<1) (sum of ∆)
m<3 = 180 - (20° + 60°)
m<3 = 100°
m<4 = 60° (corresponding angles are congruent)
Therefore, the following statements are TRUE:
B. m<3 = 100°
C. m<2 + m<4 = 80°
