Find the value of f(-2) for the function f(x) = 4x + 10.<br> A. -3<br> B. -2<br> C. 2<br> D. 18
Morgarella [4.7K]

Step-by-step explanation: If f(x) = 4x + 10, then f(-2) is 4(-2) + 10

which simplifies to -8 + 10 or 2.

So f(-2) = 2.

Suppose f is a linear function such that f(3 = 5 and f(7 = -4. find the equation for f
NeX [460]
   
\displaystyle\\   &#10;f(3) = 5 \\ &#10;f(7) = -4\\\\&#10;\texttt{Solve:}\\\\&#10;f(x)=ax+b ~~~\Longleftrightarrow~~~ y=ax+b~~~\Longleftrightarrow~~~ ax+b-y=0\\\\&#10;-------\\&#10;3a+b-5=0~~~(E1)\\ &#10;7a+b+4=0~~~(E2)\\&#10;---\\&#10;E2 - E1\\&#10;4a+9=0\\&#10;4a =-9\\\\&#10;\boxed{a =  -\frac{9}{4} = -2,25}\\\\&#10;3\times  \Big(-\frac{9}{4}\Big)  + b -5 = 0\\\\&#10;-\frac{27}{4} -5+ b = 0\\\\&#10;\frac{-27-20}{4}  + b = 0\\\\&#10;-\frac{47}{4}  + b = 0\\\\&#10;\boxed{b = \frac{47}{4} = 11,75}

Kyle held a balloon 8ft off the ground above his head and Ava is standing 15 feet directly to g the right of Kyle how far is Ava
ryzh [129]

Answer:

17

Step-by-step explanation:

Pythagorean theory baby! Okay so the Pythagorean theory is a² + b² = c² so lets draw a triangle and label our sides. So we know 8² + 15² = c² so I'm going to find the square root of all of our numbers. We get 64 + 225 = c² so then add 64 + 225 = 289 then I take the square root of 289 which equals 17 . This answer also makes sense because out hypotenuse should always be bigger then the legs.

I'm pretty sure thats right, Hope this helps.

Need help with this problem explain pls
Usimov [2.4K]
All sides of an equilateral triangle are equal, so all three sides are 9 cm.
To find h, use the pythagorean theorem. This requires use of only one right triangle, where we use b as our h.

a^2+b^2=c^2
(4.5)^2+b^2=(9)^2
(20.25)+b^2=(81)
b^2=(81/20.25) or 4
square root both sides
b=2
