Step-by-step explanation:
David wants to purchase some pens. The pens he likes cost $2 each, not including tax. This is represented by the graph below.
Notice triangle BAC.
Notice triangle BDE.
Explain how the triangles demonstrate that the rate of change is consistent for number of pens purchased and the cost.
The rate of change is always the same for a straight line no matter the points used.
The equation of a straight line is given by:
y = mx + b;
where y, x are variables, m is the rate of change and b is the y intercept.
In triangle BAC:
Rate of change = change in y(cost) / change in x(pens) = (6 - 0) / (3 - 0) = 2
In triangle BDE:
Rate of change = change in y(cost) / change in x(pens) = (8 - 0) / (4 - 0) = 2
The rate of change is always the same for a straight line no matter the points used.

-6k–10=10–10k
Answer:
k=5
Step-by-step explanation:
-6k-10=10-10k
-6k-10=-10k+10
-6k-10=-10k+10
-6k-10+10=-10k+10+10
-6k=-10k+20
-6k=-10k+20
-6k+10k=-10k+20+10k
4k=20 4k/4 = 20/4
k=20/4
k=5
Step-by-step explanation:
Rearrange your terms
-6k - 10 = 10 - 10k - Before
-6k - 10 = -10k + 10 - after rearrange
Then add 10 to both sides-6k - 10 = -10k + 10 - before adding 10
-6k - 10 + 10 = -10k + 10 + 10 - After adding 10
Simplify- add the numbers-6k - 10 + 10 = -10k + 10 + 10
-6k = -10k + 10 + 10
-6k = -10k + 10 + 10
-6k = -10k + 20
-6k = -10k + 20
Add 10k to both sides again-6k = -10k + 20
-6k + 10k = -10k + 20 + 10
Simplify again- combine like terms-6k + 10l = -10k + 20 + 10k
4k = -10k + 20 + 10k
4k = -10k + 10 + 10k
4k = 20
Divide both sides by K4k = 20 = K = 5

The y-intercept of 35 means that in 1960 there were 35 births per thousand people.The slope of , 1 point 1, means that the birth rate is increasing by about 11 births per 1000 people every 10 years. The , y, -intercept of 35 means that in 1960 there were 35 births per thousand people.The slope of 1.1 means that the birth rate is decreasing by about 110 births per 1000 people every 10 years. The y-intercept of 50 means that in 2010 there will be 50 births per thousand people.The slope of , 1 point 1, means that the birth rate is decreasing by about 110 births per 1000 people every 10 years. The , y, -intercept of 50 means that in 2010 there will be 50 births per thousand people.The slope of −0.3 means that the birth rate is decreasing by about 3 births per 1000 people every 10 years. The y-intercept of 35 means that in 1960 there were 35 births per thousand people.
Using technology, the least square regression line equation which models the data is : y = -0.3x + 35.
b.) The slope of −0.3 means that the birth rate is decreasing by about 3 births per 1000 people every 10 years. The y-intercept of 35 means that in 1960 there were 35 births per thousand people.
Given the data :
X : __ 0 ___ 10 ____ 20 ___ 30 ___ 40 ___ 50Y:__35.4 __33.6 ___28.3 __27.0 __22.4 _ 20.0Using either a linear regression calculator or excel :
y = -0.3x + 35 Slope, b = - 0.3 Intercept, c = 35The value of the slope, gives the rate of change in y per unit increase in x.
Hence, the slope value of - 0.3 means that birth rate is decreasing by about 30 births per 1000 people.The intercept is the value of y when x = 0 ; This means that the number of births in 1960(beginning of the data collection), there were 35 births per thousand people.

2(7x-34) = 22
Find X
Brainliest
Answer:
x = 6.428
Step-by-step explanation:
2(7x-34) = 22
Distribution:
2 times 7x = 14x
2 times -34 = -68
Your equation is now:
14x - 68 = 22
Add 68 on both sides to leave 14x alone
68+22 = 90
You are left with this equation:
14x = 90
Divide by 14 to isolate the x
90/14
x = 6.428 (approximately)
Answer:
The value of x is 45/7.Work:
2(7x - 34) = 22=> 14x - 68 = 22=> 14x = 22 + 68=> 14x = 90=> x = 90/14=> x = 45/7Hence, the value of x is 45/7.

Find gradient using given points:
m = gradient
Formula:
m = Δy/Δx
m = 9/3 = 3
So, equation of line will be:
y = 3x + a
a is 2 as the point (0, 2) is on the line, 2 units above origin point
The options remaining are:
y > 3x + 2 and y < 3x + 2
Consider any point in the shaded region and compare the y-value of that point with the y-value at the same value of x along the line, e.g. (0, 3) is within the shaded region, the y-value of the line at x = 0 is 2, i.e. the coordinates are (0, 2)
3 > 2 ∴ the correct inequality is y > 3x + 2

Point K is located at (7, 4) in the coordinate plane. Its image is created by the following rule: K' = Ro270°(K).
Which transformation of point K would produce the same result for K as seen in the previous question?
P.S. Pervious question
Point K is located at (7,4) in the coordinate plane. Its image is created by the following rule:
K'=Ro 270°^(k)
What are the coordinates of k'?
A. (4,-7)
B. (4, 7) This is the correct answer.
C. (7, -4)
D. (-7, 4)
After the transformation of 270° clockwise rotation we get K(7, 4)→K'(-4, 7). Therefore, option B is the correct answer.
The given coordinate point is (7, 4).
What is the transformation?A transformation is a general term for four specific ways to manipulate the shape and/or position of a point, a line, or geometric figure. The original shape of the object is called the Pre-Image and the final shape and position of the object is the Image under the transformation.
Rotation of object 270° clockwise direction
The rule of rotating a figure 270 degrees clockwise is (x, y)→(-y, x)
So, K(7, 4) rotated by 270° clockwise we get K'(-4, 7).
After the transformation of 270° clockwise rotation we get K(7, 4)→K'(-4, 7). Therefore, option B is the correct answer.

help me with which triangle it is and how do I find x?
Answer:
isosceles
x=14
Step-by-step explanation:
isosceles because of the two I symbols on the triangle
x+5=2x-9
5+9=2x-x
14=x
Step-by-step explanation:
it's an isosceles triangle,
as an Isosceles triangle have two equal sides so
→ 2x - 9 = x + 5
→ 2x - x = 5 + 9
→ x = 14
therefore, value of x is 14.
2(14) - 9 = 28 - 9 = 19
14 + 5 = 19
