there is no intercept
Answer:
it is defined determined 2×1
Answer:
4. 11
5. -11
6. ± 5
Step-by-step explanation:
4. (g - h)(x) = x² - 1 - ( -2x +3) = x² - 1 + 2x -3 = x² +2x -4
(g - h)(3) = 3² + 2.3 - 4 = 9 + 6 - 4 = 11
5. (h-g)(x) = -2x + 3 - (x² - 1) = -2x + 3 - x² + 1 = -x² - 2x + 4
(h-g)(3) = -3² - 2(3) + 4 = -9 -6 +4 = -11
6. g(x) = 24
24 = x² - 1
x² = 24 + 1 = 25
x = √25 = ± 5
Answer:
y = -3x - 3.
Step-by-step explanation:
Find the slope of the line JK:
Slope = (6-4)/(3- (-3))
= 2 / 6
= 1/3.
Therefore the slope of the line perpendicular to it is - 1 / 1/3
= -3.
Now we use the point-slope form of a line to get the required equation:
y - y1 = m(x - x1)
Here m = -3 and (x1, y1) = (3, -12) so we have
y - (-12) = -3(x - 3)
y + 12 = -3x + 9
y = -3x + 9 - 12
y = -3x - 3 is the answer.
Answer:
(8x-5y) (8x+5y)
Step-by-step explanation:
64x^2−25y^2
This is the difference of squares
a^2 - b^2 = (a-b) (a+b)
Let 64 x^2 = a^2 Then a = 8x
Let 25 y^2 = b^2 then b = 5y
64x^2−25y^2 = (8x-5y) (8x+5y)
