Answer:
y= -1/2x+2
Step-by-step explanation: Our "y-intercept" (where x = 0) acts as the foundation of our function here.
We can extrapolate from what we have here...if x is 0, y is going to be 2.
So, we start at 2 for y, and every time we decrease x by 2, y increases by 1.
If we decrease x by just 1, y increases by ½.
This also goes in the opposite direction. Increase x by 1, decrease y by ½.
We can write the change in y as -½x.
That change is being added to our original value of 4, of course.
The equation of this line is .

Give the largest whole number that could equal the length of the side in the picture.
Answer:
8
Step-by-step explanation:
We can use triangle inequality, let AC = x:
x+4 > 5
x+5 > 4
9 > x
Simplifying:
x>1
x>-1
9>x
Thus: 9>x>1
So the Largest whole number is 8

In 12 years, Janice will be 8 times as old as she was 2 years ago. How old is Janice
now?
Janice is currently 4.
In 12 years, Janice will be 16, and 2 years ago she was 2. That being said, 16 is eight times more than 2, thus meaning she is currently 4 years old.
I hope this helps!

How could writing a problem using an exponent be easier to understand than repeated multiplication?
Answer:
One reason, is because it clearer and easier to read.
Seeing two numbers (3^5) can let you know, in this example, 3x3x3x3x3 is harder to understand than 3^5.
3 is the number being multiplied, and 5 tells you how many times.

What is the length of the missing leg ?
Answer:
A=4
Step-by-step explanation:
you use the Pythagorean Theorem,
a triangle having a Leg b length of 3 and a Hypotenuse c length of 5 would have a Leg a length of 4.
Here is how I solved for Leg a using the Pythagorean Theorem.
Leg a = sqrt[ (Hypotenuse c)2 - (Leg b)2 ]
Leg a = sqrt[ (5)2 - (3)2 ]
Leg a = sqrt[ 25 - 9 ]
Leg a = sqrt[ 16 ]
Leg a = 4
Name the form of the equation, then find the y-intercept of the following lines.....
y=2/5x+1
Answer:
y = 1
Step-by-step explanation:
To find the y-intercept (s), substitute in 0 for x and solve for y.
y = 2/5 x (0)+1
y-intercepts (0, 1)

Rebecca is climbing up a 500-foot cliff. By 1:00 P.M., she has
climbed 125 feet up the cliff. By 4:00 P.M., she has reached
an altitude of 290 feet. Find the average rate of change in
Rebecca's altitude during the three hours. Give the rate in feet
per bour.
Answer:
Step-by-step explanation:
(290 ft - 125 ft)/(3 hours) = (165 ft)/(3 hours) = 55 ft/hour

how do you convert 7/6 into a mixed number or how do you covert fractions into a number in general.
Answer:
1 1/6
Step-by-step explanation:
You can convert 7/6 into a mixed number by subtracting 1 from the improper fraction, because 1= 6/6
7/6 -6/6= 1 1/6
Answer:
7/6 would be 1 1/6
Step-by-step explanation:
To make it a number in general turn into a decimal.

Given 6, 8, and 11 as the three sides of a triangle, classify it as one of the following acute, right or obtuse. Please help and thank you
9514 1404 393
Answer:
obtuse
Step-by-step explanation:
You may remember that side lengths of 3, 4, 5 make a right triangle. Doubling those lengths to 6, 8, 10 will still give a right triangle.
The given triangle has a longest side (11) longer than would be appropriate for a right triangle (10), so the largest angle is larger than 90°.
The triangle is obtuse.
__
Comparison of a triangle to a right triangle with two sides the same is one of several ways the triangle can be classified. You can use the Law of Cosines to find the largest angle, or you can use a triangle solver (as we have below).
In case you don't recall that 3-4-5 makes a right triangle, you can use the Pythagorean theorem to find the longest side of a right triangle with the given shorter sides:
hypotenuse = √(6² +8²) = √100 = 10
Your long side is longer, so your largest angle is larger than 90°.
Law of Cosines:
angle = arccos((6² +8² -11²)/(2·6·8)) = arccos(-21/96) ≈ 102.6°
Converting from vertex form to standard form
[tex]y = \frac{1}{2} (x - 2) {}^{2} - 4[/tex]
Answer:
[tex]\displaystyle f(x)=\frac{1}{2}x^2-2x-2[/tex]
Step-by-step explanation:
To convert from vertex form to standard form, we can simply expand.
So, we have:
[tex]\displaystyle f(x)=\frac{1}{2}(x-2)^2-4[/tex]
Expand the square:
[tex]\displaystyle f(x)=\frac{1}{2}(x^2-4x+4)-4[/tex]
Distribute:
[tex]\displaystyle f(x)=\frac{1}{2}x^2-2x+2-4[/tex]
Simplify:
[tex]\displaystyle f(x)=\frac{1}{2}x^2-2x-2[/tex]

Rotate the triangle 180 degrees around the origin
someone pls help:>>
Explanation:
Imagine that you cross out the top-most square for each step of each diagram. The squares not crossed out have the following counts: 1, 4, 9
This is the sequence of perfect squares. So the rule will have us take the number n, and square it to get n^2. Then we add on the squares we crossed out earlier. This explains the "plus 1" at the end to get the answer of n^2+1

sin 45 = 3 / d
1 / root 2 = 3 / d
d = 3 root 2
For second triangle,
tan 60 = 7 / a
root 3 = 7 / a
a = 7 / root 3

The point (2.5, 1) is also on the line. What is the vertical change between (2.5, 1) and (5, 2)? What is the horizontal change?
Answer:
In a general point (x, y) the horizontal component is the x-component, and the vertical component is the y-component.
then if we have the points (a, b) and (c, d)
The vertical distance or change between these points will be the difference between the y-components, and the horizontal distance or change is the difference between the x-components.
Then the vertical change between the points (2.5 , 1) and (5, 2) is:
2 - 1 = 1 unit.
The horizontal change between the points (2.5, 1) and (5, 2) is:
5 - 2.5 = 2.5 units.
