The slope is 3 true or false?
Answer:
The slope IS NOT 3.
So the statement is FALSE.
Step-by-step explanation:
y = mx + b
If we change the graph shown into the format shown above it would be:
y = 1x - 3
mx = slope
Slope = 1x
b = y-intercept
b = -3
To find the slope you must do:
[tex]\frac{y}{x} =\frac{RISE}{RUN}[/tex]
y = rise
x = run
In the graph shown, the points are going up and shift to the right 1 unit.
So the slope is: 1x
Therefore, the statement, "The slope is 3" is actually false.
2(x+3)=x-4
Anyone know the answer please lol
Answer:
The Answer is -10.mark this answer as BRAINLIEST answer. And I hoped this helpful for you....
Thank you ☺️☺️
Lets solve your equation step-by-step
2(x+3)=x-4
Step 1 :Simplify both sides of the equation
2(x+3)=x-4
(2)(x)+(2)(3) =x+-4 (distribute)
2x+6=x+-4
2x+6=x-4
Step 2: Subtract x from both sides
2x+6-x=x-4-x
x+6=-4
Step 3: Subtract 6 from both sides
x+6-6=-4-6
Answer: x=-10

-2.25x+8.75x+10-20 solve x pls
Answer:
im gonna assume the 10 - 20 is what the equation is = to if not x wouldnt be = to anything x = -1.5
Step-by-step explanation:
-2.25x + 8.75x = 10-20
-2.25x+ 8.75x = -10
6.50x = -10 divide both sides by 6.5
x = -1.5

The sum of 4 times a number and 7 equals 5.
Use the variable w for the unknown number.
Answer:
4w +7 = 5
Step-by-step explanation:
Have a nice day.
Answer:
4w + 7 = 5
Step-by-step explanation:
"sum" means addition (+), so we're to add two items:
item 1 to be added
"4times a number" means multiplication(x) of 4 and w(because w stands for the unknown number).
Therefore, 4 x w = 4w
item 2 to be added
This is the number 7
The sum
4w + 7
Now, the sum, equals(=) the number 5, therefore answer:
4w + 7 = 5
A triangle has side lengths of (8.5q+1.6r)(8.5q+1.6r) centimeters, (3.5q-4.1s)(3.5q−4.1s) centimeters, and (4.4s+5.8r)(4.4s+5.8r) centimeters. Which expression represents the perimeter, in centimeters, of the triangle?
Answer:
7.4r+0.3s+12q
Step-by-step explanation:
I am in 8th grade and we do these problems for honors algebra and if you add (8.5q+1.6r)+(3.5q-4.1s)+(4.4s+5.8r) you will get the answer above
Basic math equations and calculations play an important role in many jobs tasks. If you were working at a grocery store and your cash register was not automatically calculating the 20% off sale on someone's cereal--how would you solve this issue from the options listed below? If the cereal was normally $2.88, I would... 1 point Take $2.88 and times it by 80 for a sale price of $2.30. Subtract $0.20 for a sale price total of $2.68. Divide 20 from $2.88 for a sale price total of $0.15.
Given :
Price of cereal without off, C = $2.88 .
Percentage off, P = 20% .
To Find :
Price after applying 20% off.
Solution :
Final price = Initial price - 20 % of initial price
[tex]F = 2.88 - 2.88\times \dfrac{20}{100}\\\\F=2.88-0.576\\\\F=\$ 2.304[/tex]
Therefore, final price after sale is $2.304 .
Hence, this is the required solution.

If you travel 1000 feet in 5 minutes, what is your speed per minutes?
Answer: 200 feet
Step-by-step explanation:
1000feet/5feet= 200feet
Answer:
200 feet per minute
Step-by-step explanation:
Speed = Distance/Time
Since you want to find the "per minute", you would just divide the total distance by the number of minutes:
1000 feet / 5 minutes = 200 feet per minute
Solve:
-x/6 + 3 =8
2/7(x) = 10
-10x = -100
Answer:
-x/6 + 3 =8
x = -30
2/7(x) = 10
x = 35
-10x = -100
x = 10
Find the slope of
(-16,3), (13,8)
Answer:
= 5/29
Step-by-step explanation:
We can use the slope formula to find the slope
m = ( y2-y1)/(x2-x1)
= ( 8-3)/(13 - -16)
= ( 8-3)/( 13+16)
= 5/29
Solving a linear equation: Your hourly wage is $9.75 per hour plus
$0.80 for each unit you produce. How many units
must you produce in 1 hour so that your hourly wage
is $19.35?
Answer:
You must produce 12 units
Step-by-step explanation:
19.35 - 9.75=9.60
9.6/0.8=12
Answer:
the answer is 12 units
Step-by-step explanation:
u get 9.75 an hour and 0.80 for every unit so subtract 9.75 from 19.35 and u get 9.60 now divide that by 0.80 and u get 12 units

Marcus has to add -3mn^3 and -5mn^3 to complete the polynomial.
Marcus is rewriting a polynomial by combining like terms
What is polynomial?Polynomial equation is equation of independent variables.
Here, questions seems to be incomplete.
In polynomial, it can be of maximum endless number of term or minimum 1 term. Marcus can add any number or repeat any number. And if he revised the old number than the number could be -3mn^3 and -5mn^3.
Thus, Marcus has to add -3mn^3 and -5mn^3 to complete the polynomial.

Find the value of x.
x=
Answer:
x = 14
Step-by-step explanation:
These angles are complementary angles, meaning they have a sum of 90°.
4x + 1 + 2x + 5 = 90
6x + 6 = 90 (Added like terms.)
6x = 84 (Subtracted 6 on both sides.)
x = 14 (Divided 6 on both sides.)
[tex]\sf \longmapsto \: (4x + 1) + (2x + 5)[/tex]
It has a sum of 90 as the given angles are complementary angles.[tex]\sf \longmapsto \: 4x + 1 + 2x + 5 = 90[/tex]
[tex]\sf \longmapsto4x + 2x + 1 + 5 = 90[/tex]
[tex]\sf \longmapsto6x + 6 = 90[/tex]
[tex]\sf \longmapsto6x = 90 - 6[/tex]
[tex]\sf \longmapsto \: 6x = 84[/tex]
[tex]\sf \longmapsto \: x = \cancel\dfrac{84}{6} [/tex]
[tex]\sf \longmapsto \: x = 14[/tex]

what ordered pair would describe each intersection?
y=8-X and y=5X-40
Answer:
(8, 0 )
Step-by-step explanation:
Given the 2 equations
y = 8 - x → (1)
y = 5x - 40 → (2)
Substitute y = 5x - 40 into (1)
5x - 40 = 8 - x ( add x to both sides )
6x - 40 = 8 ( add 8 to both sides )
6x = 48 ( divide both sides by 6 )
x = 8
Substitute x = 8 into either of the 2 equations and solve for y
Substituting into (1)
y = 8 - 8 = 0
Solution is (8, 0 )
