Write the slope-intercept form of the equation of the line:
y − 2 =12(x − 1)
Answers
Answer:
y=12x+10
Step-by-step explanation: First you start off with PEMDAS and multiply 12 times x and -1. Which you'll have y - 2 = 12x - 12. Next you'll subtract 2 by both sides and your answer will be y = 12x -10
Answer:
y = 1/2x + 1 1/2
Step-by-step explanation:
Slope-intercept form is written with the formula [ y = mx + b ].
Solve for y.
y - 2 = 1/2(x - 1)
y - 2 = 1/2x - 1/2
y = 1/2x + 1 1/2

what is the answer to this? −1.3≥2.9−0.6r
Answers
Answer:
Inequality Form:
r ≥ 7
Interval Notation:
[7, ∞)
Step-by-step explanation:
−1.3 ≥ 2.9 − 0.6r
Rewrite so r is on the left side of the inequality.
2.9 − 0.6r ≤ −1.3
Move all terms not containing r to the right side of the inequality.
Subtract 2.9 from both sides of the inequality.
−0.6r ≤ −1.3 − 2.9
Subtract 2.9 from −1.3.
−0.6r ≤ −4.2
Divide each term by −0.6 and simplify.
Divide each term in −0.6r ≤ −4.2 by −0.6. When multiplying or dividing both sides of an
inequality by a negative value, f lip the direction of the inequality sign.
−0.6r /−0.6 ≥ −4.2 /−0.6
Cancel the common factor of −0.6.
−4.2
r ≥ ______
−0.6
Divide −4.2 by −0.6.
r ≥ 7
The result can be shown in multiple forms.

−6.5>6.55
−6.5≥6.55
−6.5<6.55
−6.5=6.55
Answers
Answer:
6.5 < 6.55
Step-by-step explanation:
since
6.5 can be written as 65/10
6.55 can be written as 655/100
when we take LCM of 100 and 10 we get 100.
so we will multiply 65/10 with 10 on both numerator and denominator.
we get 650/100 and 655/100 .
since denominators are same we can say that 650<655.
Hence,
6.5 < 6.55

Construct the perpendicular bisector of segment AB.
Construct a line through B perpendicular to segment AB.
Construct the line passing through A and B.
Construct a line parallel to line AB.
Answers
Answer:
2nd choice because the first wouldnt make sense because of the angle it is in
Step-by-step explanation:
We have that the constructions which would construct a line of reflection that takes point A to point B is Option D
Construct a line parallel to line AB
A line parallel to line AB will Create a line of reflection that takes point A to point B because a parallel line never meet thereby creating the direct imagery of Line AB
From the Options
We have that
-Construct the perpendicular bisector of segment AB.
A perpendicular bisector will NOT Create a line of reflection that takes point A to point B but rather it will divide the line AB in two equal parts
-Construct a line through B perpendicular to segment AB.
A line through B perpendicular to segment AB will NOT Create a line of reflection that takes point A to point B
-Construct the line passing through A and B.
A line passing through A and B will NOT Create a line of reflection that takes point A to point B but rather will create Line A and B again and not its reflection
Construct a line parallel to line AB
A line parallel to line AB will Create a line of reflection that takes point A to point B because a parallel line never meet thereby creating the direct imagery of Line AB
In conclusion
The constructions which would construct a line of reflection that takes point A to point B is Option D
Construct a line parallel to line AB
A line parallel to line AB will Create a line of reflection that takes point A to point B because a parallel line never meet thereby creating the direct imagery of Line AB

Your friend's math test contained 42 questions, some of which were worth two points while therest were worth three points.Your friend tells you that a perfect score is 100 points, but shecannot remember how many of each type (2 point or 3 point) were on the test.Help your friendout:how many of each type were on the test?
Answers
Answer: Two points = 26
Three points = 16
Step-by-step explanation:
Let the 2 points questions be represented by x
Let the 3 points questions be represented by y
Since the math test contained 42 questions, some of which were worth two points while therest were worth three points. This can be written as:
x + y = 42 ........... equation i
Since a perfect score is 100 and some questions are worth two pints while others are worth 3 points. This can be written as:
2x + 3y = 100 ........... equation ii
x + y = 42 ........... equation i
2x + 3y = 100 ......... equation ii
Multiply equation i by 2.
Multiply equation ii by 1
2x + 2y = 84 ........ equation iii
2x + 3y = 100 ....... equation iv
Subtract equation iii from iv
y = 16
There are 16 3-points questions.
Since x + y = 42
x + 16 = 42
x = 42 - 16
x = 26
There are 26 2-points questions

In an electrical circuit ,the voltage across a resistor is directly proportional to the current running through the resitor.If a current of twelve amps produces 480 volts across a resistor,how many volts would a current of 1.5 amps produce across an identical resitor?
Answers
Answer: The voltage across an identical resistor = 60 Volts
Step-by-step explanation:
Step 1
Given that voltage across the resistor is directly proportional to the current running through the resitor.
Mathematically, it would be represented as
Voltage ∝ Current
Introducing the constant of proportionality, k which represents the Resistor as it is constant.
we have that
Voltage = K x Current
When current = 12 amps and voltage = 480v, the constant of proportionality K
480 = k x 12
k = 480/12
k= 40
Step 2 ,
when current = 1.5 amps
Voltage = ?
Using our equation that
Voltage = K x Current
Voltage = 40 x 1.5
Voltage = 60 Volts
