Which input value produces the same output value for the two functions on the graph?
DiKsa [7]

Answer:

The input value is 3/4

Step-by-step explanation:

we know that

The input value that produces the same output value for the two linear functions, is the intersection point both graphs

we have

f(x)=-3x+1 ---> equation A

g(x)=x-2 ---> equation B

Equate equation A and equation B

x-2=-3x+1

solve for x

3x+x=1+2

4x=3

x=\frac{3}{4}

therefore

The input value is 3/4

Sin^2A-cos^2B=sin2^B-cos^2A​
Rashid [163]

Answer:

see explanation

Step-by-step explanation:

Using the trig identity

sin²x + cos²x = 1 , then

sin²x = 1 - cos²x

cos²x = 1 - sin²x

Consider the left side

sin²A - cos²B

= (1 - cos²A) - (1 - sin²B) ← distribute parenthesis

= 1 - cos²A - 1 + sin²B

= sin²B - cos²A

= right side , thus verified

Solve the following inequality: x+5≤(−x+2)+x
vesna_86 [32]

Answer:

<h2>x ≤ - 3</h2>

Step-by-step explanation:

x + 5 ≤ ( - x + 2) + x

<u>Remove the parenthesis</u>

That's

x + 5 ≤ - x + 2 + x

x + 5 ≤ 2

Using the subtraction property subtract 5 from both sides

That's

x + 5 - 5 ≤ 2 - 5

x ≤ 2 - 5

We have the final answer as

<h3>x ≤ - 3</h3>

Hope this helps you
