Answer:
True
Step-by-step explanation:
Logic: if 3+4 =7 then 4+3 also = 7 or 3*4 =12 then 4*3 is also 12 etc.
Answer:
Equation 1: y = 7x + 6
Equation 2: y = -7x + 8
Step-by-step explanation:
Isolate the y variables in both equations
Equation 1:
y - 7x = 6
y = 7x + 6
Equation 2:
y + 7x = 8
y = -7x + 8
So, the equations in slope intercept form are:
Equation 1: y = 7x + 6
Equation 2: y = -7x + 8
Answer:
sin 4/9 if cos is 3/5
Step-by-step explanation:
A cosine function is equivalent to the adjacent side divided by the hypotenuse , from SOH-CAH-TOA.
So, our adjacent side can be 3 , and the hypotenuse can be 5.
Then, we can use the Pythagorean theorem (a^2 + b^2 = c^2) to find the missing side length.
3^2+b^2=5^2
9+b^2 =25
b^2=16
b = 4
We found our three sides: 4, 5, and 9.
We know from SOH-CAH-TOA that the sine function is equivalent to the opposite side length divided by the hypotenuse length. So:
sin θ = 4/9
Than you check this line of terms
1. 80=160/2
2. 40=80/2
3. 20=40/2
4. 10=20/2
5. 5=10/2
6. 2 1/2 = 5/2 so what mean that choice c. is right sure
hope this will help you
