Answer:
B. (1,2)
Step-by-step explanation:
y = –x + 3.......(1)
y = 4x – 2.......(2)
Putting (1) into (2)
-x + 3 = 4x - 2
4x + x = 3 + 2
5x = 5
x = 5/5
x = 1
And putting x = 1 in (1)
y = -x + 3
y = -1 + 3
y = 2
Answer:
B. (1, 2)
Step-by-step explanation:
YEP!! YOUR ANSWER IS B (1, 2)
Putting (1) into (2)
-x + 3 = 4x - 24x + x = 3 + 2
5x = 5
x = 5/5
x = 1
And putting x = 1 in (1)
y = -x + 3
y = -1 + 3
y = 2
The equation of a line that passes through a point is an algebraic equation. It can also be referred to as the Slope-Intercept Equation.
The equation of the line that passes through the point (4, 4) and has a slope of 0 is written as: y = 4
The equation of the line through a point (x1, y1) can be represented by the algebraic equation:
y = mx + c
where:
m = slope
c = y - intercept
From the question,
(x1, y1) = (4, 4)
m = slope = 0
Substituting these values into the algebraic equation,
4 = (0 x 4) + c
Hence, y = 4
The equation of the line that passes through the point (4, 4) and has a slope of zero is y = 4

Answer:
y = 0x + 4 or y = 4.
Step-by-step explanation:
The slope is zero, and in other words, m = 0.
The slope intercept form is y = mx + b.
Replace m with 0.
y = 0m + b.
The y intercept is the y point on the line. Since this slope is a straight horizontal line, the y point given is the y intercept. b is the y intercept.
y = 0m + 4
Since any number times 0 is 0 you can right it as
y = 4.
Answer:
She only uses 12 of the applications. Then she downloads another 12 making it 24. Here is the equation: 2/3 = 12/18 (+12 = 24).
Step-by-step explanation:
Answer: In 1 hour, 12720 more times rabbit's heart beat than a dog's rabbits heart beat
Step-by-step explanation:
Since we have given that
Rabbit's heart beat in 1 min 212 times more than dog's heart beat in 1 min.
So, in 1 hour , we get,
So, in 1 hour, 12720 more times rabbit's heart beat than a dog's rabbits heart beat .
The absolute value is the size of the quantity regardless the sign and direction. This is, it tells the magnitude.
A quantity may be a scalar or a vector.
Some scalar quantitiies are mass, density, temperature, distance, number of cars. Some scalar quantities only have size (magnitude) but other also have sign, i.e. may be either positive or negative.
Scalar quantities that only have magnitude are like mass, density, or number of cars. For example, 20 grams, 1 g/cm³, and 12 cars, tell all the information about the quantities of mass, density, and cars. In theses examples the absolute value is the quantity: it tells the size of the quantity.
A good example of scalar with sign is temperature. For example, temperature in a hot day may be 30°C, and temperature in a cold day may be - 8°C. You need to include the negative sign to indicate the whole range of temperatures. But the absolute value of the temperature is the magnitude without the sign. The absolute value of 30°C is 30 and the absolute value of - 8°C is 8. Then, the absolute value tells the magnitude or size of the measurement, regardless the sign.
Some examples of vectors are position, velocity and force. To indicate positiion, velocity and force, you need to include the magnitudeand the direction. For example, 30 m at 30° North of the East is a position, 100 km/h East is a velocity, and 2000 newtons 20° above the horizontal line is a force. Yet the absolute value tells you just the magnitude or size of vector quantities. The absolute value tells the magnitude or size of the quantity regardless the direction: 30m, 100km/h, and 2000 newtons are the absolute values of those quantities; they tell you the size of the measurement but not the direction.
Then, the absolute value is always the size of the quantity regardless the sign and direction.
The absolute value is indicated by enclosing the variable inside two bars: | x | is read absolute value of x and is always positive.
