Answer:
y=-2x+19
Step-by-step explanation:
For lines like these, the slope is always defined as "the change in y over the change in x" or, in equation form: m= [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex].
Now we have,
m= 3-7/8-6
m=-2. Since m=-2, the equation is y=-2x+b.
To find b, think about what your (x,y) points mean:
(6,7). When x of the line is 6, y of the line must be 7.
(8,3). When x of the line is 8, y of the line must be 3.
Substitute them to the equation y=-2x+b.
You can use either (x,y) point you want..the answer will be the same:
(6,7). y=mx+b or 7=-2 × 6+b, or solving for b: b=7-(-2)(6). b=19.
(8,3). y=mx+b or 3=-2 × 8+b, or solving for b: b=3-(-2)(8). b=19.
So, the equation of the line that passes through the points
(6,7) and (8,3) is y=-2x+19.

What is the final amount if 1885 is increased by 5% followed by a further 18% increase
9514 1404 393
Answer:
2335.515
Step-by-step explanation:
The first increase multiplies the original amount by 1 + 5% = 1.05.
The second increase multiplies the already increased amount by 1 + 18% = 1.18.
Then the final amount is ...
1885(1.05)(1.18) = 2335.515

Gloria enjoys playing Skee ball — an arcade game where players toss a ball so it rolls up a ramp and falls into one of several slots. Each slot is worth a different number of points based on how difficult it is to land the ball in that slot. Gloria only aims at the most difficult slot, which is worth 100100100 points, but she only has a 10\%10%10, percent chance of landing the ball in that slot. If she misses, her ball will certainly land in the 101010 point slot.

Answer:
The answer is Graph D.
Step-by-step explanation:
Answer:
D.)
Step-by-step explanation:
D is the correct answer because it is the only line with a linear function that will forever increase and/or decrease. If the graph has a point using the same y-value assigned to the same x-value more than one time then it is not a function. A graph is only a function if each x-value HAS ONLY ONE y-value.

c)This statement is true.
d)This statement is false. No more than one rigid motion can be applied to any polygon.
18.) True or false: A sequence of rigid motions that maps a pre-image to an image must contain no fewer than two unique rigid motions for the pre-image and the image to be congruent.
a) This statement is false. If a sequence of rigid motions maps a pre-image to an image, the pre-image and the image are congruent no matter the details of the sequence of rigid motions.
b)This statement is true.
c) This statement is false. A sequence of rigid motions that maps a pre-image to an image must contain no more than two unique rigid motions for the pre-image and the image to be congruent.

4) b) B'. The reflection of an object about a line is as far behind the mirror as the object is in front
5.) a) The arrow will point in the southwest direction
6.) 88°. A 272° rotation clockwise, is equivalent to a 360° - 272° rotation. anticlockwise
9) 2,160°.
One rotation = 360°, 6 rotations = 6 × 360° = 2,160°
10.) d) The number of sides is even
The existence of a line symmetry gives equal number of sides on both sided of the line of symmetry, which gives an even an even number of sides
15.) a) Reflecting about the y-axis and then rotating 90° counterclockwise
Reflecting across the line y = -x, gives (x, y) → (-y, -x)
Reflecting about the y axis gives, (x, y) → (x, -y))
Rotation 90° counterclockwise gives (x, -y) → (-y, -x)
16) b) (0, 0),
Reflection about the line y = x gives (x, y) → (y, x)
Reflection about the line y = -x gives (x, y) → (-y, -x)
When, (x, y) = (0, 0), (y, x) ≡ (-y, -x)

whats the slope of 10x+4y=-20
Answer:
In Explanation
Step-by-step explanation:
First, you should put the equation in slope intercept form (y = mx + b), where m is the slope.
10x + 4y = 20
Isolate the y term
10x + 4y – 10x = 20 – 10x
4y = 20 – 10x
Rearrange the terms
4y = –10x + 20
Divide both sides by 4
4y4=−10x+204
y=−104x+5
The slope of the given line is –10/4. A perpendicular line will have a slope with the opposite reciprocal. In simpler terms, you flip the slope and change the sign, therefore, the opposite reciprocal is 4/10.

Work Shown:
40 words = (2/3) of a minute
3*40 words = 3*(2/3) of a minute ... multiply both sides by 3
120 words = 2 minutes
120/2 words = 2/2 minutes .... divide both sides by 2
60 words = 1 minute
Bob's speed is 60 words per minute (wpm)

HELP ME PLEASE!!!! explain how to solve y^4-81/y-3
Answer:
If solved by using quadratic formula, you would need to solve the rational equation by combining expressions and isolating the variable y .
y ≈ 2.45043159
Step-by-step explanation:
The expression (y⁴ - 81) / (y - 3) simplifies to (y + 3)(y² + 9) after factoring and canceling common terms.
expression (y⁴ - 81) / (y - 3)
by simplification
factoring the numerator
y⁴ - 81 = (y²)² - 9² = (y² - 9)(y² + 9)
factoring the denominator
y - 3
we get, (y² - 9)(y² + 9) / (y - 3)
simplifying
(y² - 9) = (y - 3)(y + 3)
(y - 3)(y + 3)(y² + 9) / (y - 3)
(y + 3)(y² + 9)

Answer:
The maximum height of the ball was 30 feet
The ball was in the air for 6 seconds
Step-by-step explanation:
The maximum height was 30 feet because that is the highest y-value before the y-values start decreasing. You could also call it the peak.
You would know the ball was in the air for 6 seconds because the time elapsed between it's liftoff at 0 feet and it's landing at the other 0 feet was 6 seconds.

Answer:
[tex]\frac{3}{2}[/tex]
Step-by-step explanation:
Answer:
(4)
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = - [tex]\frac{2}{3}[/tex] x - 5 ← is in slope- intercept form
with slope m = - [tex]\frac{2}{3}[/tex]
Given a line with slope m then the slope of a line perpendicular to it is
[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{-\frac{2}{3} }[/tex] = [tex]\frac{3}{2}[/tex] → (4)
Grant is buying a pack of blue and white socks. 4 of the pairs are blue and 6 of the pairs are white. What fraction is equivalent to the portion of socks that are NOT white? Question 4 options: 2/5 3/4 3/5 1/2
Answer:
[tex]Fraction = \frac{2}{5}[/tex]
Step-by-step explanation:
Given
[tex]Blue = 4[/tex]
[tex]White = 6[/tex]
Required
Determine the fraction that are not white
First, we need to determine the total
[tex]Total = Blue + White[/tex]
[tex]Total = 4 + 6[/tex]
[tex]Total = 10[/tex]
Not white, in this case means blue.
So, the fraction is calculated as thus:
[tex]Fraction = \frac{Not\ White}{Total}[/tex]
[tex]Fraction = \frac{Blue}{Total}[/tex]
[tex]Fraction = \frac{4}{10}[/tex]
Simplify
[tex]Fraction = \frac{2}{5}[/tex]
Hence the fraction that are not white is
[tex]Fraction = \frac{2}{5}[/tex]
