Answer:

See below

Step-by-step explanation:

Okay so...I might be interpreting the question wrong-if I am please comment! I'll fix it to the best of my ability.

A) Plug in -5 to all x values

   f(-5)=10(-5)-3

          ==50-3

    f(-5)= -53

B) f(0)=10(0)-3

    f(0)= -3

C) f(7)=10(7)-3

         =70-3

    f(7)=67

D) f(t^2+2)=10(t^2+2)-3

                 =10t^2+20-3

     f(t^2+2)=10t^2+17

E) f(12-x)=10(12-x)-3

              =120-10x-3

    f(12-x)=117-10x

F) f(x+h)=10(x+h)-3

             =10x+10h-3

lutik1710 [3]

Answer:

Step-by-step explanation:

Ratio=3:4

so,the pair of adjacent sides are 3x,4x

Pythagorean theorem,

(3x)^{2}+(4x)^{2}=20^{2}\\9x^{2}+16x^{2}=400\\\\25x^{2}=400\\\\x^{2}=\frac{400}{25}\\\\ x^{2}=16\\\\x=\sqrt{16}\\\\x=4\\\\length=4x=4*4=16cm\\\\breadth=3x=3*4=12cm\\\\Perimeter=2*(l+b)\\\\=2*(16+12)=2*28\\\\=56cm

If i hace 2 f's and i am homeschooled will i get held back and repeat the 7th grade?
KonstantinChe [14]
You would probably have to repeat the 7th grade, because you need to have a certain GPA, and 2 F's mean that you are only able to get 2.0 GPA, maximum. Otherwise, you'll fail. So, you have a very small chance of passing.

If g(x) = 7(x2 + 3) - 10 what is the value of g(5)?<br> a. 186<br> b. 206<br> c. 46<br> d. 20
stira [4]

Answer:

a) 186

Step-by-step explanation:

g(x) = 7(x^2 + 3) - 10

g(5) = 7((5)^2 + 3) - 10

g(5) = 7(25 + 3) - 10

g(5) = 7 × 25 + 7 × 3 - 10

g(5) = 175 + 21 - 10

g(5) = 186
