If f(x)=x^2and g(x)=6x+4,for which value of x does (f+g) =0

Mathematics

olga nikolaevna [1]3 years ago
6 0

Step-by-step explanation:

When (f + g)(x) = 0,

f(x) + g(x) = x² + 6x + 4 = 0.

Therefore (x + 3)² - 5 = 0, we have

x = sqrt5 - 3 or x = -sqrt5 - 3.

He difference of two numbers is 50. twice one number equals three times the other. find the numbers.
Juli2301 [7.4K]
X-y=50 and 2x=3y 
x=y+50 so 2(y+50) = 3y 

2y+100=3y
y=100

x-100=50
x=150

so our numbers are 150 and 100 

150-100=50 and 150 is 3*50 and 100 is 2*50 so fits all requirements!

hope this helps you! thank you!

I’m confused on this one
UkoKoshka [18]

The ratios in a 30-60-90 triangle are 1 : \sqrt[2]{3}: 2. Therefore, since the hypotenuse is the longest and it is 10, 10 / 2 is 5 meaning 5 is the smallest side.

Joanne had $115 to spend at the mall. She spent 23% of that money on a shirt. How much did Joanne spend on the shirt?
-Dominant- [34]
The answer would be $26.45.
What you do is on a calculator: 115 x 23%
Hope this helps :)

Factor:<br> 4tan^2x-(4)/(cotx)+sinx(cscx) ...?
lisov135 [29]
4tan^(2)x-((4)/(cotx))+sinxcscx 


Multiply -1 by the (4)/(cotx) inside the parentheses. 

4tan^(2)x-(4)/(cotx)+sinxcscx 


To add fractions, the denominators must be equal. The denominators can be made equal by finding the least common denominator (LCD). In this case, the LCD is cotx. Next, multiply each fraction by a factor of 1 that will create the LCD in each of the fractions. 


4tan^(2)x*(cotx)/(cotx)-(4)/(cotx)+sin... 


Complete the multiplication to produce a denominator of cotx in each expression. 

(4tan^(2)xcotx)/(cotx)-(4)/(cotx)+(cot... 


Combine the numerators of all expressions that have common denominators.
