Answer:
D
Step-by-step explanation:
I know the answer is D because I set the equation to be equal to x.
First, I added c to both sides. The equation looked like: 7x=k+c
Then, I divided 7 on both sides, so x would be by itself. The equation looked like x=k+c/7
In conclusion, the answer is D. x=k+c/7
Answer:
<u>There are two statements that are true:</u>
<u>B. QR = 5.9 cm
</u>
<u>D. Measure of angle R = 47 degrees</u>
Step-by-step explanation:
1. Let's recall that if ΔVWX ≅ ΔPQR, then:
VW ≅ PQ
WX ≅ QR
PR ≅ VX
<u>therefore, QR is 5.9 cm and not 4.5 cm</u>
2. Let's recall that if ΔVWX ≅ ΔPQR, then:
∠V ≅ ∠P
∠W ≅ ∠Q
∠X ≅ ∠R
<u>therefore, measure of ∠R is 47° and not 28°</u>
<u>There are two statements that are true:</u>
<u>B. QR = 5.9 cm
</u>
<u>D. Measure of angle R = 47 degrees</u>
Step-by-step explanation:
1) 9x - (-5 + 6x) = 9x + 5 - 6x
Solving like terms
3x + 5
2) 9x - 5 - 6x
3x - 5
3) 9x - 6x + 5
3x + 5
4) 9x - 6x - 5
3x - 5
5) 9x - (-6x + 5)
9x + 6x - 5
15x + 5
2 and 4 are the expressions
Answer:
(-5,3)
Step-by-step explanation:
The point (5,7) translated down 4 units gets to the point (5,3). If you reflect it over the y-axis, the x-coordinate becomes negative, and the y-coordinate stays the same. This gets you the point (-5,3)
Hope it helps and is correct!
Answer:
The common difference is -5/4
T(n) = T(0) - 5n/4,
where T(0) can be any number. d = -5/4
Assuming T(0) = 0, then first term
T(1) = 0 -5/4 = -5/4
Step-by-step explanation:
T(n) = T(0) + n*d
Let
S1 = T(x) + T(x+1) + T(x+2) + T(x+3) = 4*T(0) + (x + x+1 + x+2 + x+3)d = 240
S2 = T(x+4) + T(x+5) + T(x+6) + T(x+7) = 4*T(0) + (x+5 + x+6 + x+7 + x+8)d = 220
S2 - S1
= 4*T(0) + (x+5 + x+6 + x+7 + x+8)d - (4*T(0) + (x+1 + x+2 + x+3 + x+4)d)
= (5+6+7+8 - 1 -2-3-4)d
= 4(4)d
= 16d
Since S2=220, S1 = 240
220-240 = 16d
d = -20/16 = -5/4
Since T(0) has not been defined, it could be any number.
