Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify</em>
f(x) = 35x + 25
g(x) = 22x + 18
f(4) is <em>x</em> = 4 for function f(x)
g(10) is <em>x</em> = 10 for function g(x)
<u>Step 2: Find Function Values</u>
<em>f(4)</em>
- Substitute in <em>x</em> [Function f(x)]: f(4) = 35(4) + 25
- Multiply: f(4) = 140 + 25
- Add: 165
<em>g(10)</em>
- Substitute in <em>x</em> [Function g(x)]: g(10) = 22(10) + 18
- Multiply: g(10) = 220 + 18
- Add: g(10) = 238
<u>Step 3: Evaluate</u>
- Substitute in function values: 5(165) + 2(238)
- Multiply: 825 + 476
- Add: 1301
<em>r</em>≈9.61in is the answer
Due to pemdas you would have to start with multiplication. 3×12= 36. Then you do addition which would be 9+36= 45.
we can see that
the above curve is parabola
so, firstly , we can find vertex
vertex is (4,0)
now, we can use vertex formula of parabola
we can plug h and k
and we get
so, we can factor it as
