we will select each options and find zeros
(a)
for finding x-intercept , we can set g(x)=0
and then we can solve for x
now, we can factor it
we get
so, this is TRUE
(b)
we can set it to 0
and then we can solve for x
we get
so, this is FALSE
(c)
we can set it to 0
and then we can solve for x
so, this is TRUE
(d)
now, we can set it to 0
and then we can solve for x
so, this is TRUE
(e)
we have
now, we can set it to 0
and then we can solve for x
so, this is FALSE
Answer:
1. 10
2. 12
3. Sqrt 130
4. Sqrt 45
Step-by-step explanation:
To find the missing side of a right triangle, use the Pythagorean Theorem. The Pythagorean Theorem is where a and b are the legs with a being the smallest and c is the hypotenuse.
1. a=6, b=8, c=?
2. a=5, b=?, c=13
3. a=7, b=9, c=?
4. a=2, b=?, c=7
Answer:
see explanation
Step-by-step explanation:
The 2 angles form a right angle, thus their sum is 90°, hence
4x + 7 + 35 = 90
4x + 42 = 90 ( subtract 42 from both sides )
4x = 48 ( divide both sides by 4 )
x = 12

To calculate the slope m use the slope formula
m = ( y₂ - y₁ ) / ( x₂ - x₁ )
with (x₁, y₁ ) = (0, 0) and (x₂, y₂ ) = (1, 4) ← 2 points on the line
m = =
= 4
