Answer:

y = 97°

Step-by-step explanation:

z = 180 - 55 - 42 = 83

Total angle in a triangle is 180°

y = 180 - z = 180 - 83 = 97°

Smallest Zero of f(x+5)=x^2+3x+30

WARRIOR [948]

Hey there
_________________
The correct answer is:
f(x+5)=(x+5)^2+3(x+5)-10

f(x+5)=x^2+10x+25+3x+15-10

f(x+5)=x^2+13x+30 and f(x+5)=x^2+kx+30 so

k=13

Now factor x^2+13x+30

Find j and k such that jk=ac=30 and j+k+b=13 so j and k are 10 and 3 so

(x+3)(x+10)

So the two zeros occur when x=-3 and -10 the smallest of which is:

x=-10

14.88 + x = 17.05 What is the value of x?

Masteriza [31]

Answer:

x=2.17

Step-by-step explanation:

14.88+x=17.05

We move all terms to the left:

14.88+x-(17.05)=0

We add all the numbers together, and all the variables

x-2.17=0

We move all terms containing x to the left, all other terms to the right

x=2.17
