x + x + 1 + 2 = 48?
Answers
Step-by-step explanation:
x + x + 3 = 48
2x = 48 - 3
2x = 45
x = 45/2
Answer:
x = 45/2
Step-by-step explanation:
x+x+1+2 = 48
combine like terms
2x + 3 = 48
2x - 3 = -3
2x = 45
2x/2 = 45/2
x = 45/2
To prove triangles similar, we only need to prove corresponding angles congruent OR corresponding sides are proportional. However, with a quadrilateral we need to prove corresponding angles congruent AND corresponding sides are proportional. Explain in your own words why it takes more to prove quadrilaterals congruent. Include examples demonstrating how “just angles” or “just sides” is not enough.

Find the slope “m” and the y-intercept “b”. a. y = 3x − 4 b. 4x − 5y = 15
Answers
Step-by-step explanation:
Equation of a line is y = mx + b
where
m is the slope
b is the y intercept
First question
a.)y = 3x - 4
Comparing with the general equation above
Slope / m = 3
The y intercept / b = - 4
Second question
b).4x - 5y = 15
First we must write the equation in the general equation above by making y the subject
That's
5y = 4x - 15
Divide both sides by 5
That's
[tex] \frac{5y}{5} = \frac{4}{5} x - \frac{15}{5} [/tex]
We have
[tex]y = \frac{4}{5} x - 3[/tex]
Comparing with the general equation above
Slope = 4/5
Y intercept = - 3

Use the following graph to estimate the rate of change of the function at x=0.6 using the points (0,0) and (1,−0.5)
Answers
Answer:
The rate of change of the function at x = 0.6 is approximately -0.72
Step-by-step explanation:
The given information from the graph are;
Points (0, 0) and (1, -0.5)
We have that the graph is that of a cubic function, therefore;
f(x) = ax³ + bx² + cx + d
At f'(x) at (0, 0) and (1, -0.5) = 0 gives;
3ax² + 2bx + c = 0
∴ c = 0
Also
ax³ + bx² + cx + d = 0
d = 0
We have
3a(1)² + 2b(1) + 0 = 0
3·a + 2·b = 0..............(1)
a(1)³ + b(1)² + c(1) + d = -0.5
a + b + 0×(1) + 0 = -0.5
a + b = -0.5..........(2)
Multiplying equation (2) by 2 and subtracting it from equation (1) gives;
2 × (a + b = -0.5) = 2·a + 2·b = -1
3·a + 2·b - (2·a + 2·b) = 0 - (-1) = 0 + 1 = 1
a = 1
From
a + b = -0.5, we have;
1 + b = -0.5 = 0
b = -0.5 - 1 = -1.5
The equation becomes
f(x) = x³ - 1.5·x²
The rate of change of the function at x = 0.6 is therefore given as follows;
f'(x) = 3 × x² - 2 × (1.5)·x = 3·x² - 3·x
At x = 0.6, we have;
f'(0.6) = 3·(0.6)² - 3·(0.6)
f'(0.6) = 3×0.6² - 3×0.6 = -0.72
The rate of change of the function at x = 0.6 ≈ -0.72

Mount Kosciuszko is the highest mountain in Australia, with a peak of about 2,228 meters above sea level. Lake Erye has the lowest point at 15 meters below sea level. What is the difference in elevation between Mount Kosciuszko and Lake Eyre? You must show your work on your sheet on notebook paper.
A)2,243
B)2,213
C)2,250
D) 2,210
Answers
Answer:
Option (A)
Step-by-step explanation:
Heights above the sea level are denoted with positive notations and depths below the sea level with negative.
Height of the highest peak of the mountain = +2228 meters
Lowest point of the lake = -15 meters
Difference between these elevations = 2228 - (-15)
= 2243 meters
Therefore, Option (A) will be the correct option.

Step-by-step explanation:
Ax − B = C
Dy + E = F
Solve for x and y:
x = (B + C) / A
y = (F − E) / D
So the sum of x and y is:
x + y = (B + C) / A + (F − E) / D
For x + y to be as large as possible, A, E and D must be small, and B, C, and F must be large. With some trial and error:
x + y = (9 + 8) / 1 + (7 − 3) / 2
x + y = 17 + 2
x + y = 19
For x + y to be as small as possible, we want the first term to be a small fraction, and the second term to be as negative as possible. So A must be large, B + C must be small, F must be less than E, and D must be small.
x + y = (3 + 4) / 8 + (2 − 9) / 1
x + y = ⅞ − 7
x + y = -6⅛
The property can be used to remove the parentheses in the expression 1.7(x + 9).
