Answer:
y = -2 when x = 0
Step-by-step explanation:
We are given points on the line such as ( 2, 2) and (6, 10) so we can find the equation of the line then find point (x=0, y=?).
General equation of the line is y = mx +b, where m is the slope and
b is y-intercept (where the line crosses the y-axis)
The slope m = (y2-y1)/ (x2-x1) = (10-2)/(6-2) = 8/4 = 2
Now the equation is y = 2x +b
To find b we substitute any of the points that are on the line, for example
(x=2, y=2) in the equation 2=2*2+b; 2-4 =b; -2 = b
The equation is y=2x -2
If x= 0 then y=2*0 -2; y = -2
9x = 27
x = 3
y = -1
The answer is (3, -1)
Step-by-step explanation:
The steam-powered locomotive revolutionized commercial transportation by providing a durable, faster, cheaper way to move goods. The Governor Stanford was the first train on the Central Pacific, which became the first transcontinental railroad line in 1869 when it was joined with the Union Pacific.
Answer: C
<u>Step-by-step explanation:</u>
h · k(x) = 2(3x - 5)(-2x + 1)
= (6x - 10)(-2x + 1)
= -12x² + 6x + 20x - 10
= -12x² + 26x - 10
Answer:
26 kg
Step-by-step explanation:
Jim has 19,700 grams of sand.
He brings home another 6,300 grams from the beach.
Total Weight of Sand in his sandbox=19700+6300=26000 grams
However, we are required to find how many kilograms of sand Jim have in his sandbox now.
Now,
1000 grams = 1 kilogram
To convert from gram to kilogram, we divide by 1000.
26000 grams = 
kilograms =26 kg
Jim has 26 kilograms of sand in his sandbox.
