\Huge{\underline{\underline{\sf{\green{Answer:}}}}}

a) 2 (5x-3) = 24

= 10x -6 = 24

= 10x = 24+6

= 10x = 30

= x= 30/10

\boxed{\sf{x = 3}}

b) 5 (2x+1) = 50

= 10x+5=50

= 10x = 50-5

= 10x = 45

= x = 45/10

\boxed{\sf{x = 4.5}}

c) (3x+4)/2=9.5

= (3x+4)/2=95/10

( On cross multiplication )

= 10(3x+4) = 2×95

= 30x+40=190

= 30x=190-40

= 30x=150

= x=150/30

(on simplification)

\boxed{\sf{x = 5}}

d) (7+2x)/3=5

(On cross multiplication)

= 1(7+2x)=5(3)

= 7+2x=15

= 2x=15-7

= 2x=8

= x=8/2

(on dividing)

\boxed{\sf{x = 4}}

A line passes through the point (3,9) and has a slope of 4
expeople1 [14]
Point-slope form is y - y1 = m(x - x1). We just need to plug in our stuff. This gives us y - 9 = 4(x - 3). I am not sure if you need to simplify, but if you do, y - 9 = 4x - 12.

If f(x) = x+3 and g(x) = VX-1,<br> what is (fºg)(26)?
scZoUnD [109]

Answer:

26V + 2

Step-by-step explanation:

This is the same as saying f(g(x)), where x = 26

First, lets figure out what g(x) is equal to when x = 26

g(26) = V(26) - 1 = 26V - 1

Now we input 26V - 1 into f(x) for x

f(26V-1) = (26V-1) + 3 = 26V + 2
