The value of x is -5.
A function is defined as a relation between a set of inputs having one output each. In simple words, a function is a relationship between inputs where each input is related to exactly one output.
given:
f(x)=-4x-10 and f(x)=10
Now, As both represent the samefunction f(x).
so,
-4x-10= 10
-4x = 20
x= -5
Hence, the value of x is -5.

Answer:
x=-5
Step-by-step explanation:
f(x)=-4x-10 and f(x)=10
substitute in 10
10=-4x-10
add 10
20=-4x
divide by -4
x=-5
Answer:
f(t)=t²-12t+11
Step-by-step explanation:
1) Having an attentive reading, we can see from the picture two coordinate points (1,0) and (11,0).
These points, has coordinates for x and y. Since those y-coordinates are zero, we have x-intercepts. Or the zeros of a function, in a quadratic function. Those intercepts minus x values equals zero. These x-intercepts we'll rename it as t, for time.
2) Plugging it in and writing it as groups:
f(t) = returns in feet
t= for time
f(t) =(t-1)(t-11)
Distributing the factors multiplying (t-1) times (t-11), goes:
f(t) =t²-12t+11
x^2 -12x +11
We have the x intercepts so we can create the equation (x-1)(x-11). Multiply it and you get your answer
2(8x – 16) = 48

Answer:
22.5 miles per hour (rounded answer)
Step-by-step explanation:
This is a fraction equal to
18 miles ÷ 0.8 hours
We want a unit rate where
1 is in the denominator,
so we divide top and bottom by 0.8
18 miles ÷ 0.8
0.8 hours ÷ 0.8
=
22.5 miles
1 hour
=
22.5 miles
hour
= 22.5 miles per hour
Answer:
there is no miles per hour because she wasn't riding for an hour
