Answer: -5 and 9
Step-by-step explanation:
x-2 = 7
x = 9
2-x = 7
x = -5
Easy
Answer:
x = 9
Step-by-step explanation:
Since we know that the difference would mean subtraction, we also know that to find the value of the variable, we need to the reverse operation. So, we would add 7 + 2 to get 9. Hope this helps you!
Solve Tangent (x minus pi) minus cosine (x minus StartFraction 3 pi Over 2 EndFraction) = 0, x is an element of left-brace 0, 2 pi).
Answer:
x ∈ {0, π, 2π}
Step-by-step explanation:
The expression can be simplified, which facilitates an answer.
tan(x -π) -cos(x -3π/2) = 0
The tangent function has a period of π, so tan(x-π) = tan(x). The cosine function shifted right by 3π/2 is equivalent to the opposite of the sine function.
tan(x) +sin(x) = 0 . . . . substitute simpler equivalents
sin(x)/cos(x) +sin(x) = 0 . . . . use equivalent for tan(x)
sin(x)(1/cos(x) +1) = 0 . . . . factor out sin(x)
sin(x)(cos(x)+1)/cos(x) . . . . . combine terms to a single fraction
This has solutions where sin(x) = 0 and where cos(x) = -1. Those solutions are integer multiples of π.
x ∈ {0, π, 2π}

Math question from my quizziz, I don't know if it's 1/a^9 or a^9
Answer:
red or 1/a9
Step-by-step explanation:
with that it is
a^ (3-12)
a^ (-9)
and then you can't have -9 in the top so you put it on the bottom
1/ a^9
Answer:
[tex]\frac{1}{a^9}[/tex]
Step-by-step explanation:
Cancel the common factor of [tex]a^3[/tex] and [tex]a^1^2[/tex]
[tex]a^3^-^1^2=a^-9[/tex]
Same things as 3-12 = -9
Hence, [Red] or [tex]\frac{1}{a^9}[/tex] is the correct Answer.

Answer: The Philadelphia Eagles tried to blow a 19-point lead to the Chicago Bears, but managed to hold on for a 22-14 victory in a rematch of the NFC Wild Card Game to move to 5-4 on the year. Philadelphia allowed the Bears to score 14 unanswered points after taking a 19-0 lead in the third quarter, but put together one of their most impressive drives of the season in taking 8:14 off the clock in the fourth quarter, converting four consecutive third downs in the most critical junction of the game.
Chicago never got the ball back after Jake Elliott hit a 38-yard field goal with 26 seconds left to make it 22-14. Bears tight end Adam Shaheen muffed the catch on the kickoff and the Eagles recovered to deny Chicago a last ditch effort for a Hail Mary and an attempt to tie the game with a two-point conversion.
Jordan Howard scored a touchdown in his first game against his former team, finishing with 19 carries for 82 yards and a touchdown. Zach Ertz had his best game of the season as the Eagles tight end had nine catches for 103 yards and a touchdown, a 25-yard catch for his second score of 2019.
The Bears had just nine total yards in the first half, but rallied back in this game with two scoring drives in three possessions between the third and fourth quarter. Chicago's offense had no turnovers, but finished with just 164 yards of offense. Mitchell Trubisky went 10 of 21 for 125 yards with no touchdowns and a 66.6 passer rating. The Bears have lost their fourth consecutive game after a 3-1 start to the season, falling to 3-5 and remaining in last place in the NFC North.
Step-by-step explanation:
The number of points scored by the eagles is 19 points.
Suppose the points scored by the bears, eagles, and cowboys are x, x+2, x+4 respectively.
It is given the product of the points scored by the bears and cowboys was 37 more than the 8 times the sum of the points scored by the eagles and cowboys.
This means, x(x+4) =37+8(x+2+x+4)
x(x+4) =37+8(2x+6)
[tex]x^{2} +4x = 37+16x+48[/tex]
[tex]x^{2} -12x-85=0[/tex], which is a quadratic equation.
What is a quadratic equation?Any equation in the form [tex]ax^{2} +bx+c=0[/tex] is called a quadratic equation where [tex]a\neq 0[/tex].
[tex]x^{2} -17x+5x-85=0[/tex]
[tex]x(x-17)+5(x-17)=0[/tex]
[tex](x-17)(x+5)=0[/tex]
[tex]x=17[/tex]
So, eagles scored x+2 = 17+2 =19 points.
Therefore, The number of points scored by the eagles is 19 points.

Select ALL the true statements.
Answer:
A.
C.
Step-by-step explanation:
A. When adding a negative number to a positive, you subtract. 2.3 - 2.3 will equal 0.
B. When adding two negative numbers, you get an even smaller negative number. (-3.7) + (-4.1) = -7.8
C. When subtracting a negative number, the two negative signs become a positive. -12/4 is equal to 3. -2.6 + 3 is 0.4, which is positive.
D. 5/2 is the same as 2.5. If you subtract 2.5 from 2.5, you will get 0, which is not negative.
E. Two negative signs make a positive, so 72 + 100 is positive, not negative.

The function y = f (x) is linear. Given f-¹ (0) = 3 and f (1) = - 4, find the formula f (x) and f-¹ (x).
Answer:
f(3x) - 2g(x+1) = 12x - 5
Step-by-step explanation:
You've got f[g(x)] and g[f(x)] correct
However, f(3x) means substitute 3x for x in f(x):
f(3x) = 2(3x) - 3
⇒ f(3x) = 6x - 3
2g(x+1) = 2[4 - 3(x + 1)]
⇒ 2g(x+1) = 2[4 - 3x -3]
⇒ 2g(x+1) = 2[1 - 3x]
⇒ 2g(x+1) = 2 - 6x
f(3x) - 2g(x+1) = (6x - 3) - (2 - 6x)
⇒ f(3x) - 2g(x+1) = 12x - 5

Can someone help me and explain the answer to this problem: Jay's dog outgrew his rectangular pen that measured 10 feet by 14 feet. To make it larger, he increased each side length by the same amount, which increased the pen's area by 81 square feet. What is the greater side length of the larger pen in feet?
Answer:
ok so first lets find the original area which is just lenth*width
10*14=140
so they increace it by 81 so
140+81=221
then we just need to find what they increases the side by we know its the same so lets just say that x so
(10+x)(14+x)=221
x=3
so the longest time is 17 since 14+3=17

Rationalise the denominator
Answer:
30+12(square root of 5)
Step-by-step explanation:
Answer:
30 + 12[tex]\sqrt{5}[/tex]
Step-by-step explanation:
To rationalise the denominator, multiply the numerator and denominator by the conjugate of the denominator.
The conjugate of 2[tex]\sqrt{5}[/tex] - 4 is 2[tex]\sqrt{5}[/tex] + 4 , then
[tex]\frac{12\sqrt{5}(2\sqrt{5}+4) }{(2\sqrt{5}-4)(2\sqrt{5}+4) }[/tex] ← expand denominator using FOIL
= [tex]\frac{120+48\sqrt{5} }{20-16}[/tex]
= [tex]\frac{120+48\sqrt{5} }{4}[/tex] ( divide each term on numerator by 4 )
= 30 + 12[tex]\sqrt{5}[/tex]
