Answer:
y=5/4x-3/2
Step-by-step explanation:
5x+1=4y+7
4y=5x+1-7
4y=5x-6
y=5/4x-6/4
y=5/4x-3/2
Answer:
EY = 5.3 cm
Step-by-step explanation:
∵ Δ ABC similar to ΔDEF
∴ AB/DE = BX/Ey
∵ AB = 12 cm
∵ DE = 8 cm
∵ BX = 8 cm
∴ 12/8 = 8/EY
∴ 12EY = 8 × 8 ⇒ 12AY = 64
∴ EY = 64 ÷ 12 = 5.3333 ≅ 5.3 cm
Answer: -4
Step-by-step explanation:
3 times that number→3x
Difference of the square of a number and 28→x^2-28
x^2
−28=
3x
-3x
=-3x
x^2-3x-28=0
(x-7)(x+4)=0
x-7=0
x+4=0
x=7 x=-4
{Negative Solution: }-4
Negative Solution: −4
It would not make sense if you were to do
34
28
The right way is
34
28
Another example is that if you were to subtract by 1 digit by 2
78
1
This is the wrong one

1
Tan(θ) = 3 tan(θ), 0° ≤ θ ≤ 360°
Solve for θ to the nearest degree.
tan(θ) = 3 tan(θ)
Subtract tan(θ) from both sides:
0 = 2 tan(θ)
Divide by 2 both sides:
tan(θ) = 0
If (x,y) is a point on the terminal ray of θ,
then tan(θ) = y/x = 0, and y = 0.
y = 0 ==> θ = 0°, 180°, or 360° in the interval 0° ≤ θ ≤ 360°.
