<u>Answer:</u>
A) slope of equation 3x+4y-12=0 is m= and y-intercept is 3
B) slope of equation 2x+y=1 is m=-2 and y-intercept is 1.
C) slope of equation 2x-y=0 is m=2 and y-intercept is 0.
<u>Solution:</u>
The slope - intercept form equation of line is given as
y=mx+c --- eqn (1)
Where m is the slope of the line. The coefficient of “x” is the value of slope of the line.
c is the y – intercept which is the value of y at the point where the line crosses the y-axis
a) Given that
3x+4y-12=0 --- eqn (2)
On converting equation (2) in slope intercept form, we get
4y=-3x+12
On comparing equation (3) and (1) we get slope of equation (2) is and y-intercept is 3.
b) Given that
2x+y=1 …(4)
On converting equation (2) in slope intercept form, we get
y=-2x+1 …(5)
On comparing equation (5) and (1) we get slope of equation (4) is m=-2 and y-intercept is 1.
C)Given that
2x-y=0 …(6)
On converting equation (6) in slope intercept form, we get
y=2x …(7)
On comparing equation (7) and (1) we get slope of equation (6) is m=2 and y-intercept is 0.
Answer:
99
Step-by-step explanation:
6) 9/4 divided by 5/8
9/4x5/8
9x8/4x5
72/4/5
72/20
18/5
Answer: 18/5
7) 2 1/2 divided by 4 1/2
2x2+1/2 divided by 4 1/2
4+1/2 divided by 4 1/2
5/2 divided by 4 1/2
5/2 divided by 8+1/2
5/2 divided by 9/2
5/2x9/2
5/2x2/9
5x1/9
5/9
Answer: 5/9
Answer:
The side length is irrational
Step-by-step explanation:
Because the square root of 23 or 20+3 is a non-perfect square root and it's a never ending decimal.
1. 255. Because 48*5=240.240 is 15 lbs so...240+15=255
2. 272. Because 3.4*5=17.17 is 272 cups.
3.52300. Because 5-2.7=52.3. 52.3 L is 52300 ml.
4.55. Because 110*6=660. 660 inches is 55 feet.
Hope that helps.
