thus :
[tex]3x + 5 = 7x - 39[/tex]
Add both sides 39
[tex]3x + 5 + 39 = 7x - 39 + 39[/tex]
[tex]3x + 44 = 7x[/tex]
Subtract both sides 3x
[tex]3x - 3x + 44 = 7x - 3x[/tex]
[tex]44 = 4x[/tex]
Switch sides
[tex]4x = 44[/tex]
Divide both sides by 4

What is the surface area of these cuboids?
Answer:
To find the surface area of a cuboid, add the areas of all 6 faces. We can also label the length (l), width (w), and height (h) of the prism and use the formula, SA=2lw+2lh+2hw, to find the surface area.

Mr. Martin is giving a math test next period. The test, which is worth 100 points, has 29 problems. Each problem is
worth either 5 points or 2 points. Write a system of equations that can be used to find how many problems of each
point value are on the test.
Let x be the number of questions worth 5 points and let y be the number of questions worth 2 points.
O x + y = 29, 5x + 2y = 100
O x + y = 100, 5x + 2y = 29
O 5x + y = 29, 2y + x = 100
O 2x + y = 100, 5y + x = 29

n = 8
measurements: 4, 3, 6, 7, 5, 5, 4, 6
Calculate the mean.
Answer:
5
Step-by-step explanation:
mean=4+3+6+7+5+5+4+6/8mean=40/8mean =5dani uses cotton balls to make snow men for an art project. dani has 14 cotton balls, and she uses 3 cotton balls to make each snow man.dani makes as many as she can.how many snowmen does dani make
Using the appropriate arithmetic operation, the number of snowmen Danny makes is 4
Total number of cotton balls = 14
Number of cotton balls per snowmen = 3
Creating a proportional relationship thus :
3 cotton = 1 snowman
14 cotton balls = x
Cross multiply
3x = 14
Divide both sides by 3
3x/3 = 14/3
x = 4.667
Hence, the number of snowmen that can be made is 4

A tower that is 128 feet tall casts a shadow 163 feet long. Find the angle of elevation of the sun to the nearest
degree.
The angle of elevation is
degrees. (Round to the nearest degree.)
Tan(angle) = opposite/ adjacent
Tan(angle) = 128/163
Angle = arctan(128/163)

$500*0.045 = $22.5
A: Tyler makes $22.5 in commision
($55-$20)/$20*100 = 175% markup

4. If f(x) = x2, g(x) = 5x, and h(x) = x +4, find each value.
Find h[f(4)].
Step-by-step explanation:
f(x) = x²
g(x) = 5x
h(x) = x + 4
= h[f(4)]
= x + 4
= f(4) + 4
= (4)² + 2
= 16 + 2
= 18
h[f(4)] = 18
A linear function contains the points (-3, -7) and (6,-4). Which of the following points does it also include?
A.(-9,3)
B.(3,-6)
C.(12,2)
D.(9,-3)
The given points defines a line from which the linear function can be
determined and the included point on the line can be found.
The point also included on the line is D. [tex]\underline {(9, \, -3)}[/tex]
Reasons:
The given points on the linear function are; (-3, -7), (6, -4)
The slope of the line is given as follows;
[tex]Slope, \, m =\dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
Therefore, we get;
[tex]Slope, \, m =\dfrac{-4-(-7)}{6-(-3)} = \dfrac{1}{3}[/tex]
The equation of the function is therefore;
[tex]y - (-4) = \dfrac{1}{3} \cdot (x - 6)[/tex]
[tex]y = \dfrac{x}{3} - 6[/tex]
Graphing the above equation on the calculator gives the points;
(-9, -9), (3, -5), (12, -2), and (9, -3)
Therefore;
The point also included on the line is D. [tex]\underline {(9, \, -3)}[/tex]

What is the range of the function y= 2e7-1?
Answer:
The range of y = ex is all numbers greater than 0, so since the function has been shifted up 1, the new range of the function is all numbers greater than 1. Since the argument of any log must be greater than 0, (x-1)/2 > 0. Thus x - 1 > 0, so x > 1
Answer:
defines the set of values [ 1, 2, 3, 4, 5 ], and the range
1 : 3 : 5
defines the set of values [ 1, 4 ].
Although a range constant specifies a row vector, Octave does not normally convert range constants to vectors unless it is necessary to do so. This allows you to write a constant like 1 : 10000 without using 80,000 bytes of storage on a typical 32-bit workstation.
A common example of when it does become necessary to convert ranges into vectors occurs when they appear within a vector (i.e., inside square brackets). For instance, whereas
x = 0 : 0.1 : 1;
defines x to be a variable of type range and occupies 24 bytes of memory, the expression

Write an equation in point-slope form for the line through the given point with the given slope.
(4, –6); m = 3/5
A. y - 6 = 3/5 (x+4)
B. y - 4 = 3/5 (x+6)
C. y + 6 = 3/5 x-4
D. y + 6 = 3/5 (x-4)
Answer:
D. y + 6 = 3/5 (x-4)
Step-by-step explanation:
Use the given slope and point to substitute into the point-slope formula y − y 1 = m ( x − x 1 ) .
Slope-intercept form: y = 3 /5 x − 42 /5
Point-slope form: y + 6 = 3 /5 ⋅ ( x − 4 )

QUESTION TWO Determine whether or not a constant function can be
(a)one-to-one.
(b)an onto function. [10 marks]
=========================================================
Explanation:
The graph of any constant function is a horizontal flat line. The output is the same regardless of whatever input you select. Recall that a one-to-one function must pass the horizontal line test. Horizontal lines themselves fail this test. So this is sufficient to show we don't have a one-to-one function here.
Put another way: Let f(x) be a constant function. Let's say its output is 5. So f(x) = 5 no matter what you pick for x. We can then show that f(a) = f(b) = 5 where a,b are different values. This criteria is enough to show that f(x) is not one-to-one. A one-to-one function must have f(a) = f(b) lead directly to a = b. We cannot have a,b as different values.
----------------------------
The term "onto" in math, specifically when it concerns functions, refers to the idea of the entire range being accessible. If the range is the set of all real numbers, then we consider the function be onto. There's a bit more nuance, but this is the general idea.
With constant functions, we can only reach one output value (in that example above, it was the output 5). We fall very short of the goal of reaching all real numbers in the range. Therefore, this constant function and any constant function can never be onto.
A tournament has 187 athletes. There are 91 more girls than boys. Let X represent the number of girls and let Y represent the number of boys. Write the system of equations that represents this situation
Answer: Need more info
Step-by-step explanation:
The system of equations that represents this situation will be;
⇒ 2Y + 91 = 187
What is linear expression?
A linear expression is an algebraic expression where each term is either a constant or a variable raised to the first power.
Given that;
Total athletes in a tournament = 187
And, In a tournament 91 more girls than the boys.
Now,
Let X represents the number of girls.
Let Y represents the number of boys.
Since, There are 91 more girls than the boys.
So, We can formulate;
X = 91 + Y
And, There are 187 athletes in a tournament.
So, We can formulate;
X + Y = 187
Substitute X = 91 + Y in above equation as;
91 + Y + Y = 187
91 + 2Y = 187
Thus, The system of equations that represents this situation will be;
⇒ 2Y + 91 = 187
