Answer:
<h3>5x+10y=100</h3>
Step-by-step explanation:
X+Y = 15
<h3>Sum of two types of question is 15</h3>
x+y-x = -x+15
<h3>y= -x+15</h3>
5(x)+10(y)=100
5x+10y=100
<h3>Total no. if points is 100</h3>
5x+10y-5x=-5x+100
10y= -5x+100
y=5/10x + 100/10
y= -1/2x+10
<h3>Slope intercept form</h3>
(10,5)
Answer
x - 2y = -1.
Step-by-step explanation:
Slope = (3 - (-2)) / (5 - (-5))
= 5/10
= 1/2
Using the point-slope form of a straight line equation:
y - y1 = m(x - x1)
Here m = 1/2 and (x1, y1) = (5, 3):
y - 3 = 1/2(x - 5)
y - 3 = 1/2x - 5/2
y = 1/2x - 5/2 + 6/2
y = 1/2x + 1/2
Removing the fractions:
2y = x + 1
in standard form this is
x - 2y = -1
Distribute the -2.5 to 4X and -3
It should look like -2.5 x 4X and -2.5 x -3(the answer for -3 should be positive)
