The function f(x)=0.39x+10.9 can be used to predict diamond production. For this function, x is the number of years after 2000, and f(x) is the value (in billions of dollars) of the year's diamond production. Use this function to predict diamond production in 2006 The diamond production in 2006 is predicted to be $[ ] nothing billion.
Answer:
The diamond production is 2006 is expected to be 13.24 billion
Step-by-step explanation:
Here, we want to predict the diamond production is 2006
The equation to use is given in the question as;
f(x) = 0.39x + 10.9
Since x is the number of years after 2006, in this particular question, x will be 2006-2000 = 6
So f(6) = 0.39(6) + 10.9
f(6) = 2.34 + 10.9
f(6) = 13.24 billion

The sets of numbers 3, 4, 5, and 8, 15, 17 are Pythagorean triples. Use what you know about the Pythagorean Theorem and explain or show why they are Pythagorean triples. Be sure to show your work for each set of triples!
Answer:
Pythagorean Theorom: a^2+b^2=c^2
Take the largest number of each as C (hypotenuse)
3,4,5
(3)^2+(4)^2= (5)^2
25=25
Therefore it is a Pythagorean Triple.
8,15,17
(8)^2+(15)^2=(17)^2
289=289
Therefore it is a Pythagorean Triple.

Write an equation of the line that passes through point (−3, 8) and has the slope m=−2.
Answer:
y=-2x+8
Step-by-step explanation:
slope formula is y=mx+b
slope(m)=-2, and y-value(b)=8
so ya just plug in what ya know to get y=-2x+8
The equation of the line that passes through point (−3, 8) and has the slope m=−2 is [tex]y=-2x+2[/tex]
What Is y = mx + c?The slope-intercept form of the equation of the line is represented by the equation y = mx + c. It requires the line's y-intercept and slope value, "m." We must first comprehend the line's slope m and y-intercept in order to comprehend this equation for the line.Slope: The letter "m" stands for the line's gradient or slope. The slope here could be zero, positive, or negative. With reference to the x-axis, the tangent of this line's angle of inclination can likewise be used to compute the slope.Intercept: The term "intercept" in this equation refers to the value "c," which is the line's starting point. The length of the line's y-axis intersection, measured from the origin, is known as the intercept. It can also be thought of as the line's intersection point at (0, c) on the y-axis.The slope formula can be used to create the equation y = mx + c. Here, we choose a random point (x, y) on the line and a point (0, c) on the y-axis. We try to determine the slope'm' of the line using these two points. The slope of the line is equal to the difference between the two points' y coordinates divided by the difference between their x coordinates.m = (y - c)/(x - 0) mx = y - c and m = (y - c)/xy = mx + c So, using the formula for the slope of a line, we can successfully deduce the slope-intercept form of the equation of a line.Given, x= -3, y = 8 and m = -2
usiny y =mx+c
we get,
8 = -2*-3+c
8 = 6+c
c = 8-6 = 2
Therefore, The equation of the line that passes through point (−3, 8) and has the slope m=−2 is [tex]y=-2x+2[/tex]

Use the figure to find the measures of Z1 and 22
Answer:
∠ 1 = 149°, ∠ 2 = 31°
Step-by-step explanation:
∠ 1 and 31° are same-side interior angles and are supplementary, thus
∠ 1 = 180° - 31° = 149°
∠ 2 and 31° are alternate angles and congruent, thus
∠ 2 = 31°

Find the slope of each line (each block is one unit):
Answer:
1. 7
2. -3
4. -4/6
Step-by-step explanation:
i solved using y2-y1/x2-x1
Answer:
1. slope= 7
2. slope= -3
3. slope= -2/3
Step-by-step explanation
you find slope by doing rise over run (how much you have to go up/down and left/right to get to the next point.
for the first one, to get from the bottom point to the top point, you have to rise 7, and go to the right 1, which makes 7/1, simplified to 1.
for the second one, you go to rise 6, and then go to the left 2, which makes 6/-2, it is negative because when you have to go left, it just means a negative slope. this simplifies to -3
for the third one, you rise 4 and go to the left 6 from the bottom point to the top point. this makes 4/-6, simplifies to -2/3/

Is 2,710,506 divisible by 8?
Answer:
no
Step-by-step explanation:
Solve the inequality. −2≤x−11≤6
Answer:
9≤x≤17
Step-by-step explanation:
In order to solve this equation, you need to just add 11 to each side
-2≤x-11≤6
to
9≤x≤17
The reason that 11 was added to this equation was that we were trying to isolate x, and it goes without saying that (x-11)+11 is x . 11 was added to the other sides because it is an inequality and that will keep it balanced.
The value of the variable 'x' will be more than or equal to 9 and less than or equal to 17.
What is inequality?Inequality is defined as an equation that does not contain an equal sign. Inequality is a term that describes a statement's relative size and can be used to compare these two claims.
The inequality is given below.
−2 ≤ x − 11 ≤ 6
Add 11 on each side of the inequality. Then we have
−2 + 11 ≤ x − 11 + 11 ≤ 6 + 11
9 ≤ x ≤ 17
The value of the variable 'x' will be more than or equal to 9 and less than or equal to 17.

Two-thirds of the T-shirts in a T-shirt shop are blue. Three-fifths of those T-shirts are on sale. One-half of the blue T-shirts that are on sale are size medium. What fraction of the shop's T-shirts are blue T-shirts that are on sale and are size medium? Explain.
Let, total number of T-shirts are x.
Number of blue T-shirts = (2/3)x = 2x/3 .
Number of blue shirts on sale = (3/5)(2x/3) = 2x/5 .
Number of medium sized blue shirts on sale = (1/5)(2x/5) = 2x/25 .
Fraction of the shop's T-shirts are blue T-shirts that are on sale and are size medium = [tex]\dfrac{2x/25}{x}[/tex]= 2/25 . ( Number of medium sized blue shirts on sale divided by total number of T-shirts )
