Find a perfect point, in this case I used the y-intercept (0,5), and find the slope. Then plug into the equation y - y1 = m (x - x1) and simplify. This will give you the slope point form of the line.
Answer:
Step-by-step explanation:
Rise over run.
m= (y2-y1)/ (x2-x1)
plug in (2,1) and (1,3)
so the slope is -2
point slope form y=mx+b
m is the slope
y = − 2 x+
Assume the average child weighs 40 pounds at age 3. Assume the
average child weighs 70 pounds at age 6. What is the average number of
pounds the child gains per year between ages 3 and 6?
Answer:
10 i think
Step-by-step explanation:
Answer: 10 pounds per year
The given unit rate is 30 pounds every 3 years.
Now, we will divide 30 pounds by 3 years.
30 pounds ÷ 3 years = 10 pounds per year
The answer is 10 pounds per year.
The highest point in the mountains of Seattle is 5,833 meters above sea level. The lowest point in the valley is 57 meters below sea level. What is the difference between the highest and lowest point?
Answer: 5890 meters
Step-by-step explanation:
Given: The highest point in the mountains of Seattle is 5,833 meters above sea level.
The lowest point in the valley is 57 meters below sea level.
in integers it is represented by -57 meters. [we use negative integer to represents "below"]
Difference between the highest and lowest point = Highest point - lowest point
= 5,833 meters -(-57) meters
= (5833 + 57) meters [a-(-b)= a+b]
= 5890 meters
Hence, the required difference = 5890 meters

Which line shows the graph of y = 4x - 5 reflected over the y-axis?
y = 4x + 5
y = 4x - 5
Y=2x-5
y = -2x + 5
Answer:
The line y = -4x - 5 shows the reflection over the y-axis.
From the attached graph, the blue line i.e. y = -4x-5 represents the reflection over the y-axis.
Step-by-step explanation:
When we reflect a line function over the y-axis, all we need is to negate the x-coordinate or value of 'x', while y-coordinate or y-value remains the same.
Given the function
y = 4x-5
replace x with -x
y = 4(-x) - 5
y = -4x - 5
Thus, the line y = -4x - 5 shows the reflection over the y-axis.
From the attached graph, the blue line i.e. y = -4x-5 represents the reflection over the y-axis.
From the graph, it is clear that that that x-coordinate of y = 4x-5 is negated.

Answer:
third option
Step-by-step explanation:
Differentiate using the product rule
Given f(x). g(x) then the derivative is
f(x). g'(x) + g(x). f'(x) ← product rule
Given
[tex]\frac{d}{dx}[/tex](x² secx )
with f(x) = x² and g(x) = secx , then
f'(x) = 2x and g'(x) = secxtanx, thus
[tex]\frac{d}{dx}[/tex](x² secx)
= x². secxtanx + secx. 2x ← factor out xsecx from each term
= xsecx(xtanx + 2) → third option

One side of a right triangle is 8 cm shorter than the hypotenuse and 7 cm shorter than the third side. Find the lengths of the sides of the triangle.
Answer:
5 cm
Step-by-step explanation:
Let the shorter side be a, longer side be b, hypotenuse be c
By Pythagorean theorem:
a² + b² = c²
a² + (a + 7)² = (a + 8)²
a² + a² + 14a + 49 = a² + 16a + 64
a² - 2a - 15 = 0
a² + 3a - 5a - 15 = 0
a(a + 3) - 5(a + 3) = 0
(a + 3)(a - 5) = 0
a = -3 or a = 5
Because a is a side length and is a positive number
a = 5

What are coordinates in a graph?The coordinates in a graph indicate the location of a point with respect to the x-axis and y-axis.
The coordinates in a graph show the relationship between the information plotted on the given x-axis and y-axis.
We have,
The equation of a line y = (1/2)x - 1
We will find some coordinates from the equation.
When x = 1,
y = 1/2 - 1
y = -1/2
When x = 2,
y = 1/2 x 2 - 1
y = 1 - 1 = 0
When x = 3,
y = 1/2 x 3 - 1
y = 3/2 - 1
y = 1/2
When x = 4.
y = 4/2 - 1
y = 2 - 1
y = 1
The coordinates that we can plot on the graph are:
(1, -1/2), (2, 0), (3, 1/2), and (4, 1)

First, divide 108 by 12.
The result is 9.
Now square root 9.
The result is 3.
Now, multiply 12 by 3.
The result is 36.
To check that this is the pattern, we multiply 36 by 3, and we indeed see that 3 times 36 is equal to 108.

How can we use ratios and proportional relationships to help us in our daily lives?
Answer:
In cooking (recipes).
Step-by-step explanation:
If the serving size for a recipe is not adequate for the number of people you are serving, you will have to convert the amounts(measurements) of the ingredients to suit your needs. You will do this by first creating a ratio defining the relationship between the serving size of the given recipe to the number of people needed to be served. For example, if a recipe serves 4 people, and you need to serve 8, your ratio would simplify to 1/2. This means you must proportionally relate this ratio to the individual amounts of each ingredient.
