x+y=−3
2x−3y=29
Answer:
(4,-7)
Step-by-step explanation:
Answer:
(4,-7)
Step-by-step explanation:
2x-3y=29
2x+2y=-6
subtracting gives us -5y=35 so y is -7 and x-7=-3 so x is 4. therefore the ordered pair is (4,-7)

-6(2v)+3a(3); v=1/3 a=2/3
Answer:
0
Step-by-step explanation:
-6(2(1/3)+3(2/3(3))=
Starting with pedmas (parenthesis, exponents, division, mulitplication, addition, subtraction).
We look at 2*1/3 and 2/3*3
[tex]2*\frac{1}{3}=\frac{2}{3}[/tex] and [tex]\frac{2}{3}*3=2[/tex]
[tex]-6(\frac{2}{3})+3(2)[/tex]=-6+6=0
[tex]v = \dfrac 13 ,~ a = \dfrac 23\\\\-6(2v) +3a(3)\\\\=-12v + 9a\\\\=-12\left(\dfrac 13 \right) + 9 \left( \dfrac 23 \right)\\\\=-4+ 3 \cdot 2 = -4 +6 = 2[/tex]
Find the value of x
[tex]24\%ofx = 90[/tex]
x=375
Answer:
Solution given:
24% of x=90
or [tex]\frac{24}{100} *x=90[/tex]
[tex]\frac{6*x}{25}=90[/tex]
6x=90*25
6x=2250
x=[tex]\frac{2250}{6}[/tex]
x=375

(5.4*10^2)-(1.3*10^4)
answer in a*b form
Answer:
-1.24*10^4
Step-by-step explanation:
Firstly observe the Digit term of the given operation under scientific notation. and now we are left with the 10th exponents which involves the basics of 10^a - 10^b = 10^a/b and so according to this rule...we have 10^2/10^4 which results in 10^-2
and thus we have −12460 = -1.24*10^4
Question involving derivatives and limits...
What is the limit as x approaches 2 of (3 f(x) - 15) / (x-2)... where f(2) is 5. The answer is not 0, I checked.

Which value is equivalent to the expression 7^2 − 3^4?
A) -3^2
B) -1^9
C) 1^6
D) 3^2
Answer:
Option B
Step-by-step explanation:
Answer:
None of these are equal to the equation in question.
When solved 7^2 - 3^4 = -32
-3^2 = -9
-1^9 = -1
1^6 = 1
3^2 = 9
So none of the answer choices are equal to the equation in question.

solve for x, find the measure of all angles plzzzzz!!
Answer:
∠ H = 22.5°, ∠ I = 45° , ∡ J = 112.5°
Step-by-step explanation:
The 3 angles in a triangle sum to 180° , then
x + 2x + 5x = 180 , that is
8x = 180 ( divide both sides by 8 )
x = 22.5
Then
∠ H = x = 22.5°
∠ I = 2x = 2 × 22.5° = 45°
∠ J = 5x = 5 × 22.5° = 112.5°
Use the remainder theorem to find P(-3) for P(x) = 2x² + 4x²+4.
Specifically, give the quotient and the remainder for the associated division and the value of P(-3).
Quotient= ?

Answer:
P ( 3 ) = 16
the remainder is
P ( a )
Did I get this right originally? I think I did.
that’s what I thought first, but the things right. each x value IS associated with only one y value. If there was more than one arrow pointing from one x value, it wouldn’t be a function, because it would mean one x value has more than one y value. I hope that made sense!

Tyrod needs at least $820 to buy the computer he wants. He has already saved $330. He earns $50 per lawn that he cuts. What is the least number of lawns that he can cut and buy the computer? Which inequality represents the problem?
[tex]▪▪▪▪▪▪▪▪▪▪▪▪▪ {\huge\mathfrak{Answer}}▪▪▪▪▪▪▪▪▪▪▪▪▪▪[/tex]
The equation representing the given statement is ~
[tex]50x + 330 \geqslant 820[/tex]The least number of lawns that he can cut and buy the computer is 10 lawns ~
[tex] \large \boxed{ \mathfrak{Step\:\: By\:\:Step\:\:Explanation}}[/tex]
Total savings should be greater or equal to $ 820 in order to buy the computer,
And his total savinga is equal to ~
Money he saved + money got from cutting lawns.
let's assume the lawns cut by Tyrod be x,
Money earned by cutting lawns is equal to
total number of lawns cut × $5050xtotal savings is equal to ~
330 + 50xhence,
[tex]50x + 330 \geqslant 820[/tex]by solving for " x (number of lawns cut) " we get ~
[tex]50x \geqslant 820 - 330[/tex][tex]50x \geqslant 490[/tex][tex]x \geqslant 490 \div 50[/tex][tex]x \geqslant 9.8[/tex]Hence, the least number of lawns he has to cut is the number that is greater than 9.8, which is

Brainliest please if correct
the function that best represents the data is y = 0.75x + 4.5. The slope in this case represents the increase in the amount she spends in $ due to the number of cards she makes. The intercept with the Y axis (4.5) means that she has an expense of 4.5 $ without having made any card yet.

Complete the puzzle so that each row, column, and diagonal adds up to the same total.
Answer:
0 , 5
-1 , 1
-3
Step-by-step explanation:
Each row, column and diagonal adds up to 3 because of the column on the right.
The bottom row must add up to 3, so the blank there is -3.
The diagonal from the bottom left corner to the upper right corner also must add up to 3, so the blank in the middle is 1.
The column in the middle must add up to 3, so the blank at the top is 5.
The top row also must equal to 3, so the blank on the left is 0.
The left column also must equal to 3, so the last blank left is -1.
