Describe a situation that could be represented by the equation 7x-8+=-56.
1. Describe a situation that could be represented by the equation 7x-8+=-56.
x = 7x - 8 = -56
x = 7x = -56 + 8
x = 7x = -48
x = -48/7
2. What is represented by the sand of time !
The sands of time is an English idiom relating the passage of time to the sand in an hourglass
The image of the sand being emptied in the hourglass creates a visual metaphor for the limited duration of human life, and for the inevitability of change in the world as a whole
3. The line equation which is trough point (-3,7) and having gradient -2 is
(y-y1) = m (x-x1)
(y-7) = -2 (x-(-3))
y-7 = -2 (x+3)
y-7 = -2x -6
y+2x = -6 +7
y+2x = 1 atau -2x-y = -1

11. find the equation of the straight line which passes through the point (-2,4) and is parallel to the line y=2x +5.
y = 2x + 5
m = 2
y - b = m(x - a)
y - 4 = 2(x -(-2))
y - 4 = 2(x + 2)
y - 4 = 2x + 4
y = 2x + 4 + 4
y = 2x + 8
12. The gradien of the equation y = 3x – 6 is
Jawaban:
Ia arter mah ........ .....
13. find the equation of the straight line which has a gradient of 2 and which passes through the point (2,1).
y-y1=m(x-x1)
y-1=2(x-2)
y=2x-4+1
y=2x-3
mungkin gitu(?)

15. trend equetion, the projeted annual sales ( in dollar ) of a new product are given by the equation S = 150.000 + 3000t, where t is the time in years from 2005. such an equation is called a trend equation. find the projeted annual sales for 2010. is S a function of t?
Jawaban:
projected annual sales for 2010 is:
S = 150.000 + 3.000 (5)
= 165.000
we get the value of t from
t = 2010 - 2005
= 5
Yes, S is a function of t

17. find the equation of the circle whose radius is 5 which touches the circle x² + y² - 2x -4x -20 = 0
Penjelasan dengan langkah-langkah:
x² + y² - 2x -4y -20 = 0
cari titik pusatnya dulu
x = –(–2)/2 = 1
y = –(–4)/2 = 2
jadi pusatnya (1, 2)
dengan r=5
kita cari titik potongnya
dengan :
(a+1)/2 = 5
a + 1 = 2(5)
a = 10-1
a = 9
(b+2)/2 = 5
b+2 = 2(5)
b = 10-2
b = 8
Persamaannya menjadi :
(x - a)² + (y - b)² = r²
(x - 9)² + (y - 8)² = 5²
x² - 18x + y² - 16y + (-9)² + (-8)² - 5² = 0
x² + y² - 18x - 16y + 81 + 64 - 25 = 0
x² + y² - 18x - 16y + 120 = 018. What is the equation of axis of symmetry of the given quadratic equation? * y = x2 – 8x - 9
Jawaban:
x = 4
Penjelasan dengan langkah-langkah:
x = -b/2a
= -(-8)/2(1)
= 4
Jawaban:
x = 4

19. What is the chemical equation for photosynthesis?
Sun,and Water
Sorry wrong
Jawaban:
The process of photosynthesis is commonly written as: 6CO2 + 6H2O → C6H12O6 + 6O2. This means that the reactants, six carbon dioxide molecules and six water molecules, are converted by light energy captured by chlorophyll (implied by the arrow) into a sugar molecule and six oxygen molecules, the products.
