Answer:3/3 i think
Step-by-step explanation:
Answer:
Step-by-step explanation:
First, we need to find the common denominator between 3/4 and 2/3. The least common factor of these fractions is 12. Now we can turn 3/4 into 9/12, and 2/3 into 8/12, simply by multiplying. To figure out what one third is, we can divide by 2 to get 4/6 and 3/6... And now I'm lost (*￣∀￣) *embarrassed face lol*

What is the answer I don’t understand how to do it
Answer:
= -22
Step-by-step explanation:
In a simple way to say it, all you have to do is add.
Remember that two negatives being added together will remain a negative.
Think of a number line, -11 would be on the left side of the 0. If you subtract another 11, you move 11 spaces more to the left. This gives you -22.
Or simply add the 11 and then add the negative sign next to it.
-(11+11)= -22
Hope this helps! :)

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:
3•(a-9)
——————— • 7 = 0 • 7
7
Now, on the left hand side, the 7 cancels out the denominator, while, on the right hand side, zero times anything is still zero.
The equation now takes the shape :
3 • (a-9) = 0
Equations which are never true:
4.2 Solve : 3 = 0
This equation has no solution.
A a non-zero constant never equals zero.
Solving a Single Variable Equation:
4.3 Solve : a-9 = 0
Add 9 to both sides of the equation :
a = 9
One solution was found :
a = 9

Respond to the following question with either a TRUE or FALSE: "The following parabola opens down: f (x) = -x2 + 5"
O TRUE because the leading coefficient is negative.
O TRUE because the linear function is negative.
O FALSE because the 5 is.positive.
O FALSE because this function is actually linear and not a parabola.
O I'm not sure how to approach this problem...yet.
Answer: A) True because the leading coefficient is negative
Explanation:
The leading term is -x^2 since this term has the largest exponent.
The leading coefficient is -1 as it's the coefficient of the leading term.
It might help to write -x^2 as -1x^2
The negative leading coefficient makes the parabola open downward, so each endpoint goes off to negative infinity. The graph looks like a frowny face. You can think of a negative emotion going with a frowny face, so that negative emotion matches with the negative leading coefficient. There are probably other ways to remember but that's the trick I use.

John took all his money from his savings account. He spent 198 on a radio and 4/12 of what was left on presents for his friends. Of the money remaining, John put 2/9 into a checking account and the last remaining 980 was left to charity. How much money did John originally have in his savings account?
Answer:
John had $2088 originally in his savings accounts.
Step-by-step explanation:
Let John had $x originally in his saving account
He spent $198 on a radio. The remaining money = x - $198
4/12 of what was left, he spent on presents for his friends. Remainig money = x - 198 - 4/12*(x-198)
= (1 - 4/12) of (x-198)
= 2/3 of (x-198)
John then put 2/9 if his remaining money into a checking account.
Now, the remaining money = 2/3*(x-198) - 2/9 of (x-198)
= (1 - 2/9) * 2/3*(x-198)
= 7/9 * 2/3*(x-198)
= 14/27(x-198)
Money left with him = $980
14/27(x-198) = $980
x - 198 = $980 * 27 / 14
x - 198 = 1890
x = 1890 + 198
x = 2088
Hence, John had $2088 originally in his savings accounts.

Lines AB and CD are straight lines. Find x and y. Give reasons to justify your solutions.
Answer:
x= 14
y=5
Step-by-step explanation:
AOC and BOD are vertical angles so they are equal
AOC = BOD = 25
MOD = 90
MOD = MOB+ BOD
90 = 3x+23 + 25
Combine like terms
90 = 3x +48
Subtract 48 from each side
90-48 = 3x
42 = 3x
Divide by 3
42/3 = 3x/3
14 =x
We know that 5y+ 3x +23+90 = 180 since AB is a straight line
5y+ 3x +113 = 180
subtract 113 from each side
5y+3x =67
5y+ 3*14 =67
5y +42 = 67
5y = 67-42
5y = 25
Divide by 5
y = 25/5
y =5

FIND THE DISTANCE BETWEEN EACH PAIR OF POINTS. ROUND TO THE NEAREST TENTH. (-4, 5) (4, 0)
Answer:
+9.4 to the nearest tenth
Step-by-step explanation:
(-4, 5) (4, 0)
Refering to the x-coordinates and the y-coordinates of these two points, we see that x changes from -4 to 4, a change of 8, which forms the horizontal leg of a right triangle. Simultaneously, y changes from 5 to 0, a change of 5, which forms the vertical leg. Now use the Pythagorean Theorem to determine the length of the hypotenuse of this triangle; this hypotenuse is the distance between the two points:
distance = +sqrt(8^2 + 5^2) = +sqrt(64 + 25) = + sqrt( 89) = +9.43 to the nearest hundredth and +9.4 to the nearest tenth.

Which error did Mathieu make?
He factored incorrectly.
He did not use the constant as the x-intercept.
He set the factored expressions equal to each other.
He incorrectly solved the equation x + 3 = x + 1.
Answer:
C
Step-by-step explanation:
Plz mark brainliest
The error is he set the factored expressions equal to each other(option3).
What is X-intercepts?In a graph, the point where the line or curve crosses the axis is called the intercept. If a point crosses the x-axis it is x-intercepts. If a point crosses y-axis it is y-intercepts.
For finding x-intercepts of the given function,
First we have to factorize the given equation and then find the x values .
In [tex]f(x)=x^{2} +4x+3[/tex]
When we factorize we get , (x+3) and (x+1)
i.e., x+3=0⇒x=-3, x+1=0⇒x=-1.
That is x- intercept is -1 and -3.
Instead of this step Mathieu equated x+3=x+1.
This makes an error.
Hence, the error is he set the factored expressions equal to each other.
