Terri wrote the equation using slope-intercept form for the line that passes through the points (4, 6) and (–2, 3). Step 1: m = StartFraction 4 minus (negative 2) Over 6 minus 3 EndFraction = StartFraction 6 Over 3 EndFraction = 2 Step 2: 3 = 2 (negative 2) + b Step 3: 3 = negative 4 + b. 7 = b. Step 4: y = 2 x + 7 Which best describes Terri’s first error? In step 1, the slope of the line should be One-half. In step 2, she should have substituted the point (4, 6). In step 3, she should have subtracted 4 from both sides of the equation. In step 4, the m and b values should be switched.
Answer:
(A) In step 1, the slope of the line should be One-half
Step-by-step explanation:
Terri calculated the slope as (x1 -x2)/(y1 -y2). Her first error was using this formula, when she should have used ...
m = (y1 -y2)/(x1 -x2)
= (6 -3)/(4 -(-2)) = 3/6 = 1/2
The best of the offered descriptions is ...
In step 1, the slope of the line should be One-half
Answer:
y = (1/2)x + 4
Step-by-step explanation:
As we move from the point (-2, 3) to the point (4, 6), x (the 'run') increases by 6 and y (the 'rise')increases by 3. Therefore the slope of the line connecting the two points is m = rise / run = 3/6, or m = 1/2.
We want the slope-intercept form of the equation of this line. The basic form is y = mx + b. Arbitrarily choosing to use the point (4, 6) and using m = 1/2, we get:
6 = (1/2)(4) + b, or b = 4.
Then the desired equation is y = mx + b, or y = (1/2)x + 4
An isosceles triangle has two sides of equal length, a, and a base, b. The perimeter of the triangle is 15.7 inches, so the equation to solve is 2a + b = 15.7. If we recall that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side, which lengths make sense for possible values of b? Select two options. –2 in. 0 in. 0.5 in. 2 in. 7.9 in.
The answer is 0.5 and 2 in.

a map that was created using a scale of 1 inch : 3 miles shows a lake with an area of 4.5 square inches. What is the actual area of the lake?
Answer:
the area represents 40.5 square miles
Step-by-step explanation:
Since 1 inch represents 3 miles, then 1 inch x 1 inch = 1 square inch represents 3 mi x 3 mi = 9 square miles
Therefore, 4.5 square inches would represent 4.5 x 9 square miles = 40.5 square miles

Two angles are supplementary. One angle measures 2x, and the other angle measures 3x - 15. Which equation can you use to find the measure of each angle? 2x + 3x - 15 = 90° 2x - 3x - 15 = 180° 2x - 3x - 15 = 90° 2x + 3x - 15 = 180°
Answer:
2x+3x-15=180°
Step-by-step explanation:
When two angles are supplementary, their angles would equal to 180° total when added together. In this answer, the two angles are added together to create 180°.
Answer:
The answer is D
Step-by-step explanation:
Supplementary angles add up to be 180 degrees, so you put the two angles together equal to that
-3(k-8)-(k+5)=23 please explain how to do this
Answer:
k = -1
Step-by-step explanation:
-3(k-8)-(k+5)=23
Distribute
-3k +24 -k-5 = 23
Combine like terms
-4k +19 = 23
Subtract 19 from each side
-4k +19-19 = 23-19
-4k = 4
Divide by -4
-4k/-4 = 4/-4
k = -1
Answer:
k = -1
Step-by-step explanation:
Use the distributive property to eliminate parentheses. That property tells you that the outside factor multiplies each term inside parentheses:
-3(k -8) -(k +5) = 23
-3k -3(-8) -k -(+5) = 23
-3k +24 -k -5 = 23 . . . . simplify
-4k +19 = 23 . . . . . . . . . collect terms
-4k = 4 . . . . . . . . . . . . . subtract 19 from both sides
k = -1 . . . . . . . . . . . . . . . divide both sides by -4

The rule for manipulating equations is, "any operation performed on one side of the equation must also be performed on the other side." Operations include addition, subtraction, multiplication, division, application of a function. Using the distributive property and collecting terms are ways to simplify equations that don't affect the truth of the equal sign (if those are done correctly).
In general, you make use of inverse operations to undo the operations you don't want. The goal is to get the variable by itself on one side of the equal sign.

Bottlenose Dolphin: 40 = 20 miles per hour
King Penguin: 40 = 5 miles per hour
Swordfish: 60 miles per hour
Answer:
It takes the Dolphin 2 hours for swimming 40 miles. The penguin takes 8 hours and the swordfish will take 2/3 of an hour, which is 40 minutes to travel 40 miles.
Step-by-step explanation:
Given :
The bottlenose dolphin travels 40 miles in 2 hours. Or it takes 20 miles in 1 hour.
Now, dividing the distance by unit rate given in the question:
40/20=2 hours
40/5=8 hours
40÷60= 2/3 hour

Greetings from Brasil...
Let's apply the given formula:
A = (1/2)·B·H
The base of this polygon (in this case, the triangle) is B
B = X² - 2X + 6
The height of this polygon is H and is H
H = X + 4
Applying these values (B and H) in the given formula.....
A = (1/2)·B·H
A = (1/2)·(X² - 2X + 6)·(X + 4)
A = (1/2)·(X³ + 2X² - 2X + 24)
A = (X³/2) + X² - X + 12

This isosceles triangle has two sides of equal length, a, that are longer than the length of the base, b. The perimeter of the triangle is 15.7 centimeters. The equation 2a + b = 15.7 models this information. If one of the longer sides is 6.3 centimeters, which equation can be used to find the length of the base? 6.3+b=15.7 12.6+b=15.7 2a+6.3=15.7 2a+12.6=15.7
Hey There!!
The answer to this is: isosollese triangle has 2 equal sides that are longer than legnth of base
perimiter=15.7
equation is 2a+b=15.7
so if the longer side is 6.3, wat is legnth of base
we know that identical sides are bigger so 6.3 is one of the identical sides
2a means the 2 idneical sides
2(6.3)+b=15.7
12.6+b=15.7
subtract 12.6 from btohs ides
b=3.1

Answer:
y = 6x
Step-by-step explanation:
Choose two points on the graph of this line for the purpose of calculating the slope (rise/run). One such point is (0, 0), which is a good choice because both x and y are exactly zero there. Another point would be (16, 96), as the line goes through this point exactly.
Then the slope is m = rise / run = 96/16 = 6.
We'll use y = mx + b, with x = 0 and y = 0, learning immediately that b must be 0.
Thus, the equation of this graph is y = mx + b => y = 6x, which is a proportional relationship.
Hi Dear Brainly User!
Answer: y = 6x
y and x:
12 - 2
24 - 4
36 - 6
.......
If we want to find m, we divide y by x. (m: the slope)
m = y/x = 12/2 = 24/4 = 36/6 = ... = 6
We use for find the y:
y = ax + b
Then, we write y = 0 and x = 0 on the formula.
And we find the b is 0.
If we multiply the slope by x, we get y.
y = 6*x = 6x
