Answer:
the equation for the line that passes through (1,2) and (3,10) is
Explaination:
1) Apply the slope formula: y^2 - y^1 divided by x^2 - x^1.
2) y^2 is 10
y^1 is 2
x^2 is 3
x^1 is 1
3) 10 - 2 = 8
3 - 1 = 2
8/2 = 4
Slope: 4
Equation: y = 4x + b
4) Replace y with either y^2 or y^1, and replace x with either x^2 or x^1.
5) 10 = 4(3) + b
6) 10 = 12 + b
7) subtract 12 from both sides.
-2 = b
y-intercept: -2
equation: y= 4x - 2
Answer:
The original cost is
$385
Step-by-step explanation:
Step one:
given data'
cost of bicycle= $138
helmet = $16
Total cost = 138+16= $154
Step two:
let the original cost be x
we are told that 40% of x= 154
hence
40/100*x= 154
0.4x=154
divide both sides by 0.4
x= 154/0.4
x=$385
Answer:
3.25,
Step-by-step explanation:
no it doesnt appear to be so. I did the math it said no
Answer:
Solve for x. The multiplicity of a root is the number of times the root appears. x=0(Multiplicity of 1)x=−4 (Multiplicity of 3)x=3(Multiplicity of 5)
Step-by-step explanation:
Well, lets start with #3!
<1 is equivalent to <3 because they are vertical angles.
This means that <2 and <4 are congruent because they are vertical angles. We know that a straight line is 180 degrees. So, <1 and <2 added together will equal 180, therefore, <2 is ___________
Since the two lines are parallel, any angle on the other side is congruent, as long as that angle is in the same place as the other. So, we can see that <1 and <7 are in the same place, just moved down. So, <7 is __________.
