Passes through (2,-4) parallel to y = 1/2x + 5

Step-by-step explanation:

Slope-intercept form:

where:

When two lines are parallel, their slopes are the same. Mak a new equation with the same slope:

Now we need to find the value of b. Insert the given point for x and y:

Solve for b.

Simplify multiplication. Follow the rule :

Isolate the variable. Subtract 1 from both sides:

The y-intercept is -5. Insert, replacing the "+":

:Done

13

step-by-step explanation:

169-1=168

168-3=165

165-5=160

160-7=153

153-9=144

144-11=133

133-13=120

120-15=105

105-17=88

88-19=69

69-21=48

48-23=25

25-25=0

since it took 13times to completely subtract it hence its square root is 13

step-by-step explanation:

the true statements are:

r = set of real numbers

n = set of natural numbers, 1,2,

w = n u{0} = {0,1,}
