Answer:
2
Step-by-step explanation:
start counting from the y axis and when it touches the curve trace it down to X axis
Answer:
C
Step-by-step explanation:
first, let's find the midpoint of line TR.
((x1+x2)/2, (y1+y2)/2)
(4+8)/2= x-coordinate= 6
(-4+-4)/2=y-coordinate=-4
(6,-4) is the point of A
now, use the distance formula for U (5,-6) and A (6,-4)
d= sqrt (x2-x1)^2 + (y2-y1)^2
d= sqrt (6-5)^2 + (-4-(-6))^2
d= sqrt (1+4)
d= sqrt 5
C. sqrt 5
The possible values of b are 7 and 8
<h3>How to determine the possible values of x?</h3>
The expression is given as:
4x² + bx + 3
Next, we test the options to determine the values of b
<u>Option 1: b = 13</u>
So, we have:
4x² + 13x + 3 ---- this cannot be factorized
<u>Option 2: b = 7</u>
So, we have:
4x² + 7x + 3
Expand
4x² + 4x + 3x + 3
Factorize
4x(x +1) + 3(x + 1)
Factor out x + 1
(4x + 3)(x + 1) ------ this can be factorized
<u>Option 3: b = 8</u>
So, we have:
4x² + 8x + 3
Expand
4x² + 6x + 2x + 3
Factorize
2x(2x +3) + 1(2x + 3)
Factor out 2x + 3
(2x + 3)(2x + 1) ------ this can be factorized
<u>Option 4: b = 1</u>
So, we have:
4x² + x + 3 ---- this cannot be factorized
Hence, the possible values of b are 7 and 8
