1.
Find the slope of the line.
Ay
a) -574
b) 5/4
c) -4/5
d) 4/5
Answer:
a) -5/4
Step-by-step explanation:
Slope is fundamentally rise/run; The points on the line are relative to each other by decreasing/increasing the y-value of +/-5 and decreasing/increasing the x-value by +/-4
The function is decreasing so the slope has to be negative.
The only possible answer choice is -5/4 or a.

Use an equation to find the value of k so that the line that passes through (1,3) and (5,k) has a slope of m=2
Answer:
k=11
Step-by-step explanation:
Slope is calculated by dividing the change in y over the change in x. The change in x for these points is 4. This leaves us with y/4 as the slope, which must equal 2. Divide both sides of the equation (y/4=2) by 4. y=8
Now add 8 to the y coordinate of (1,3) in order to get a y value of 11 for the second coordinate.
What is the volume of a cube that is 4 millimeters on each side?
select the equation represented by the graph
Answer:
b) y = -2/3 + 1
Step-by-step explanation:
The format for the equation is y = mx + b
(m is the slope, and b is the y intercept)
Slope is rise over run (the units the line moves up and the units the line moves to the right)
In this case, the slope is: -2/3 because it goes down 2 and to the right 3.
The y intercept is 1.
This makes our equation:
y = -2/3 + 1
decide whether the equation describes a function
y-2x=-4
yes or no
Answer:
yes

The perimeter of a triangle is 20 cm. The lengths of the sides are x, x + 3, and x + 5.
What is the length in centimeters of the longest side?
The side of the longest triangle would be 9cm.
Step-by-step explanation:First, we need to find x
To do this, we add all 3 sides together to get the perimeter (20) :
x + x + 3 + x + 5 = 20
3x + 8 = 20
We then use this equation to find x :
3x + 8 = 20
(minus 8 on both sides)
3x = 12
(divide by 3 on both sides)
x = 4
Now we have x, we substitute it into the longest side (x + 5)
4 + 5 = 9cm.
Melanie used cross multiplication to correctly solve a rational equation. She found one valid solution and one extraneous solution. If 3 is the extraneous solution, which equation could she have solved?
A. The equation is 4/x-3 = x/10 because 3 makes a denominator equal zero and is not a solution of the equation derived from cross multiplying.
B. The equation is x-3/4 = 2x-6/4x because 3 makes a numerator equal zero and is a solution if the equation derived from cross multiplying.
C. The equation is 8/x^2-9 = 5/2x-6 because 3 makes the denominator equal zero and is a solution of the equation derived from cross multiplying.
D. The equation is 8/x+3 = 12/4x-3 because 3 is a solution of both the original equation and the equation derived from cross multiplying.
Answer:
The equation is 4/x-3 = x/10 because 3 makes a denominator equal zero and is not a solution of the equation derived from cross multiplying. ( A )
Step-by-step explanation:
The equation is 4/x-3 = x/10 because 3 makes a denominator equal zero and is not a solution of the equation derived from cross multiplying.
An extraneous solution is a solution that is derived from an equation that is not the original equation and when its value is plugged back into the original equation it isn't a root of the equation

Answer:
x^2 -10x+25
Step-by-step explanation:
(x-5)^2
Rewriting
(x-5)(x-5)
FOIL
first: x*x = x^2
outer: x* -5 = -5x
inner: -5*x = -5x
last: -5 * -5 = +25
Add them together
x^2 -5x-5x+25
Combine
x^2 -10x+25
Answer:
x^2 - 10x + 25
Step-by-step explanation:
Use FOIL.
(x - 5)^2 = (x - 5)(x - 5) = x^2 - 5x - 5x + 25 = x^2 - 10x + 25
A cabinet has shelves that are 11 1/2 in. Apart. On one shelf, brad stacked a cd player that is 5 1/4 in. High on top of an amplifier that is 4 1/8 in. High. How much space is left above the cd player?
Answer:
Step-by-step explanation:
Given the total space in the shelf = 11 1/2 in
Total spaced used = 5 1/4 + 4 1/8
Total spaced used = 21/4 + 33/8
Total spaced used = 42+66/16
Total spaced used = 108/16
Total spaced used = 6 12/16
Total spaced used = 6 3/4 in
Amount of space left = 11 1/2 - 6 3/4
Amount of space left = 23/2 - 27/4
Amount of space left = (46-27)/4
Amount of space left = 19/4
Amount of space left = 4 3/4 in
Hence the amount of space left in the shelf is 4 3/4 inches
2.) Two teachers worked out on the treadmill at the gym.
Mr. Geiger walked 2 miles in ¾ hour.
Mr. A walked 1 ¾ miles in 30 minutes
Who walked a faster rate? Show and explain your reasoning.
Answer_________________________________________________________________________
______________________________________________________________________________.
Answer:
Mr.A walked a faster rate
Step-by-step explanation:
Mr. A walked a faster rate since he walked 1 3/4 miles in 30 minutes which is 17.14 minutes a mile when dividing 30/1.75. Mr Geiger walked a slower rate 2 miles in 3/4 hours, 45/2 = 22.5 minutes per mile.

Find the value of the variable.
In triangle ABC, AB¯¯¯¯¯¯¯¯=14, BC¯¯¯¯¯¯¯¯=27, AC¯¯¯¯¯¯¯¯=19, and ∡A=32°. In triangle FGH, FG¯¯¯¯¯¯¯¯=14, GH¯¯¯¯¯¯¯¯=19, FH¯¯¯¯¯¯¯¯=2y+5, and ∡G=32°.
Answer: ???
Answer:
The variable, y is 11°
Step-by-step explanation:
The given parameters are;
in triangle ΔABC; [tex]{}[/tex] in triangle ΔFGH;
Segment [tex]\overline {AB}[/tex] = 14 [tex]{}[/tex] Segment [tex]\overline {FG}[/tex] = 14
Segment [tex]\overline {BC}[/tex] = 27 [tex]{}[/tex] Segment [tex]\overline {GH}[/tex] = 19
Segment [tex]\overline {AC}[/tex] = 19 [tex]{}[/tex] Segment [tex]\overline {FH}[/tex] = 2·y + 5
∡A = 32° [tex]{}[/tex] ∡G = 32°
∡A = ∠BAC which is the angle formed by segments [tex]\overline {AB}[/tex] = 14 and [tex]\overline {AC}[/tex] = 19
Therefore, segment [tex]\overline {BC}[/tex] = 27, is the segment opposite to ∡A = 32°
Similarly, ∡G = ∠FGH which is the angle formed by segments [tex]\overline {FG}[/tex] = 14 and [tex]\overline {GH}[/tex] = 19
Therefore, segment [tex]\overline {FH}[/tex] = 2·y + 5, is the segment opposite to ∡A = 32° and triangle ΔABC ≅ ΔFGH by Side-Angle-Side congruency rule which gives;
[tex]\overline {FH}[/tex] ≅ [tex]\overline {BC}[/tex] by Congruent Parts of Congruent Triangles are Congruent (CPCTC)
∴ [tex]\overline {FH}[/tex] = [tex]\overline {BC}[/tex] = 27° y definition of congruency
[tex]\overline {FH}[/tex] = 2·y + 5 = 27° by transitive property
∴ 2·y + 5 = 27°
2·y = 27° - 5° = 22°
y = 22°/2 = 11°
The variable, y = 11°
what is the x cordinate of the solution
Answer:
x = - 4
Step-by-step explanation:
Given the 2 equations
y = - 2x - 5 → (1)
y = x + 7 → (2)
Substitute y = x + 7 into (1)
x + 7 = - 2x - 5 ( add 2x to both sides )
3x + 7 = - 5 ( subtract 7 from both sides )
3x = - 12 ( divide both sides by 3 )
x = - 4
