Answer:
I believe the answer is X=2.5
Step-by-step explanation:
7+2=9
so now we have to find what X would be so we can do the second equation
So we know that the second equation must equal 6 because 9+6=15
So now we experiment with different numbers for X
if we did 2, the new equation would be 2x2+1 which is 5, too low
if we did 3, the new equation would be 2x3+1 which is 7, too high
So we need something in the middle
in the middle of 5 and 7 is 6 which is the number we need
so to get 6 we need something in between 2 and 3, which in 2.5

during one day ,the temperature in circle city rose from -5° to 7° how many degrees did the temperature rise?
Answer:
13 degrees, I think.
Step-by-step explanation:
On a number line -5 is to the left, so you'd count over to the right until you got to 7 which would result into your answer being 13. (not 100% sure)

Solve 2(x + 1) = 2x + 5. All real numbers No solution 0 3
Answer: No solution 0=3
Step-by-step explanation:
2(x+1)=2x+5
Step 1: Simplify both sides of the equation.
2(x+1)=2x+5
(2)(x)+(2)(1)=2x+5(Distribute)
2x+2=2x+5
Step 2: Subtract 2x from both sides.
2x+2−2x=2x+5−2x
2=5
Step 3: Subtract 2 from both sides.
2−2=5−2
0=3

The opposite of a number is always positive true or false
Answer:
false
Step-by-step explanation:
if the number is already positive it will be negative
Answer:
false
Step-by-step explanation:
False
The opposite of a negative number is positive.
The opposite of a positive number is negative.
The opposite of zero is zero and is neither positive nor negative.
Therefore, the opposite of a number is not always positive.
Answer: false

A bowl contains 5 red chips, 7 blue chips, 6 yellow chips, and 10 green chips. One chip is
randomly drawn.
Find P(blue).
75%
33%
25%
Explanation:
There are 7 blue out of 5+7+6+10 = 28 chips total.
7/28 = 1/4 = 25/100 = 25% is the probability of pulling out a blue chip.

25(b+3)=11(b-7) using distributive property when solving equations.
Answer:
b = -76/7
Step-by-step explanation:
Step 1: Write equation
25(b + 3) = 11(b - 7)
Step 2: Solve for b
Distribute: 25b + 75 = 11b - 77
Subtract 11b on both sides: 14b + 75 = -77
Subtract 75 on both sides: 14b = -152
Divide both sides by 14: b = -76/7
Step 3: Check
Plug in b to verify it's a solution.
25(-76/7 + 3) = 11(-76/7 - 7)
25(-55/7) = 11(-125/7)
-1375/7 = -1375/7
Answer:
b= -10.85
Step-by-step explanation:
25(b+3)=11(b-7)
25b+75=11b-77
+77 +77
25b+152=11b
-25b -25b
152=-14b
-14 -14
-10.8571=b

How do I do #1 ? Help!!
1) First find the multiplier.
Look at the 0 and 1st term you have 5 as the 0 and 3 as the 1st term.
2)Ask how do we get from 5 to 3?
We subtract 2 so the multiplier is -23)Lets make a linear equation: y=mx +b
m= multiplier or slopex= Just equals x valueb= your starting value or the 0 term which is 54)Use the values that you have to create your equation.
y=-2x +5Note:For the x value just plug in the x value from your table.
Ex.
y=-2(-10)+5y=20+5y=25King Tut has a castle with one hundred rooms that all have doors labeled 1 to 100 that are shut. His
crazy son Calvin runs around the castle and opens all the doors. Then he runs around the castle and
closes every other door (2, 4, 6, 8, ... 100). Then he runs around the castle and when he comes to
every third door (3,6,9,12,...99) if it is open he closes it and if it is closed he opens it. He then does
the same for every 4th door, then every 5th door and then every 6th door, and so on until then does
it for every 100th door. At the end of this exhausting run clearly door 1 is open, but what other door
are also open? (hint: Grappling would suggest you try using a smaller number like 20 doors and see
if there is a pattern)

represents the inverse of the function f(x) = 4x?
Answer:
F(x)= 4x
y=4x
now, switch the variables
x= 4y
simplify the equation so that y is by itself. Divide each side by 4
x/4= y
or f(x)= x/4 is the answer
Step-by-step explanation:
Answer:
x/4 = f(x)
Step-by-step explanation:
First you put Y in for f(x)
1. y=4x
Then you flip x and y so you are solving for x
2.x=4y
Now, you divide by 4 to solve
3. x/4=y

A ball is dropped from a height of 25feet and allowed to bounce until it comes to a rest. Each time the ball bounces it rebounds to 4/5 of its previous height
Drag tiles to create an equation you could use to find the height to which the ball rebounds after it hits the floor the third time,h3
H3= ...•... ...
3,4,4/5,25
Answer:
[tex]H3 = 25 * \frac{4}{5} * \frac{4}{5}* \frac{4}{5}[/tex]
Step-by-step explanation:
Given
[tex]Initial\ Height =25[/tex]
[tex]Rebound = \frac{4}{5}[/tex]
Required
Determine the height at the third rebound
At first rebound;
[tex]H1 = 25 * \frac{4}{5}[/tex]
Second rebound
[tex]H2 = 25 * \frac{4}{5}* \frac{4}{5}[/tex]
Third rebound
[tex]H3 = 25 * \frac{4}{5} * \frac{4}{5}* \frac{4}{5}[/tex]
Hence; the equation is:
[tex]H3 = 25 * \frac{4}{5} * \frac{4}{5}* \frac{4}{5}[/tex]
Solving further;
[tex]H3 = 12.8\ ft[/tex]

Answer:
m=14
Step-by-step explanation:
Step 1:
m
Simplify —

Equation at the end of step 1 :
m
(3 • — ÷ 3) - 7 = 0

STEP 2 :
m
Divide — by 3

Equation at the end of step 2 :
m
(3 • —) - 7 = 0

STEP 3 :
Rewriting the whole as an Equivalent Fraction
3.1 Subtracting a whole from a fraction
Rewrite the whole as a fraction using 2 as the denominator :
7 7 • 2
7 = — = —————
1 2
Equivalent fraction : The fraction thus generated looks different but has the same value as the whole
Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator
Adding fractions that have a common denominator :
3.2 Adding up the two equivalent fractions
Add the two equivalent fractions which now have a common denominator
Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:
m - (7 • 2) m - 14
——————————— = ——————
2 2
Equation at the end of step
3
:
m - 14
—————— = 0

STEP

:
When a fraction equals zero
4.1 When a fraction equals zero ...
Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.
Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.
Here's how:
m-14
———— • 2 = 0 • 2
2
Now, on the left hand side, the 2 cancels out the denominator, while, on the right hand side, zero times anything is still zero.
The equation now takes the shape :
m-14 = 0
Solving a Single Variable Equation:
4.2 Solve : m-14 = 0
Add 14 to both sides of the equation :
m = 14
One solution was found :
m = 14
10= j/6 help me plss
Answer:
j=60
Step-by-step explanation:
j=60
I multiplied. 6*10=60. Then I checked to see if it made sense.
60/6=10. Yes, it is valid.
Answer:
j= 60
Step-by-step explanation:
To find j multiply 6 by 10 which is 60.
When you replace j with 60 it will make sense as 60 / 6 is 10.

Determine if the relation is a function. In your handwritten work, explain why or why not.
y = 0.5x - 6
Answer:

Step-by-step explanation:
The relation is a polynomial. Every polynomial is a function, so the relation is a function. (Each value of x produces a single corresponding value of y.)
