The last one hope this helps
Y=Mx+b b is always on the y intercept so that canceled out c and b is canceled out Bc the Mx is negative and it can’t just be 6 Bc there is no point on where it clear like right on the point if u can understand that so that just leaves u with d y=-7/6x-7
A)
y=2^x
4^x=2^(2x)=y²
solution:
y=2^x hence y²=4^x
chek:
x=5 ⇒ y=2⁵=32
4⁵=1024
y₂=32²=1024
b)
8(4^x)-9(2^x)+1=0
8(2^(2x)-9(2^x)+1=0
2^x=t
8t²-9t+1=0
We solve the quadratic.
t₁=1/8 ⇒2^x=1/8
2^x=1/2³
2^x=2⁻³
x=-3
t₂=1 ⇒ 2^x=1 ⇒x=0
Solutions:
x=-3
x=0
Answer:
inches and feet
Step-by-step explanation:
because we arent like all the other countries tha tuse kilograms and kilometers and stuff like that.
Answer:
B
Step-by-step explanation:
A linear equation has the highest degree of 1.
In other words, there is only one x, and this x is to the first power.
Graphically, linear equations are lines.
Hence, the correct answer is B.
A is incorrect because it is the reciprocal of x, which is a rational function.
C and D are incorrect because the highest degree is 2, making them quadratics.
