What is Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given:
x + 2y = 14............(1)
x + y = 8
x = 8 - y.................(2)
Solving equation (1) and (2), we get
8 - y + 2y = 14
y + 8 = 14
y = 14 - 8
y = 6
and, x + y = 8
x + 6 = 8
x = 8 - 6
x = 2

(a) The table
[tex]\begin{array}{cc}x & {f(x)} & {0} & {0} & {1} & {7}& {2} & {12} & {3} & {15} & {4} & {16} & {5} &{15} & {6} & {12} & {7} &{7} & {8} & {0}\ \end{array}[/tex]
(b) See attachment for graph
(c) He swapped the values of the x and y coordinates for one another
Step-by-step explanation:
Given
See attachment for complete question
Solving (a): Complete the table
[tex]f(x) = -x^2 + 8x[/tex]
[tex]x = 0[/tex]: [tex]f(0) = -0^2 + 8*0 = 0 + 0 = 0[/tex]
[tex]x = 1[/tex]: [tex]f(1) = -1^2 + 8*1 = -1 + 9 = 7[/tex]
[tex]x = 2[/tex]: [tex]f(2) = -2^2 + 8 *2 = -4 + 16 = 12[/tex]
[tex]x = 3[/tex]: [tex]f(3) = -3^2 + 8 *3 = -9 + 24 = 15[/tex]
[tex]x = 4[/tex]: [tex]f(4) = -4^2 + 8 *4 = -16 + 32 = 16[/tex]
[tex]x = 5[/tex]: [tex]f(5) = -5^2 + 8 *5 = -25 + 40 = 15[/tex]
[tex]x = 6[/tex]: [tex]f(6) = -6^2 + 8 *6 = -36 + 48 = 12[/tex]
[tex]x= 7[/tex]: [tex]f(7) = -7^2 + 8 *7 = -49 + 56 = 7[/tex]
[tex]x = 8[/tex]: [tex]f(8) = -8^2 + 8 *8 = -64 + 64 = 0[/tex]
So, the complete table is:
[tex]\begin{array}{cc}x & {f(x)} & {0} & {0} & {1} & {7}& {2} & {12} & {3} & {15} & {4} & {16} & {5} &{15} & {6} & {12} & {7} &{7} & {8} & {0}\ \end{array}[/tex]

Step-by-step explanation:
a) For the 4 letters of the word ROCK
Selecting any first letter, we have 4 options
for the second, we have 3 options

for the fourth, we have only one option
So the number of ways will be ;
4 * 3 * 2 * 1 = 24 ways

An engineer needs to determine the distance across a river without swimming to the other side. The engineer notices a tree on the other side of the river and suddenly has an idea.
Describe how she will sketch her idea to be able to determine the distance. Make a sketch and support you figure by number use meter as unit.
Answers
Answer:
Step-by-step explanation:
The engineer can use a clinometer to measure the angle of elevation of the top of the tree. Let the height of the tree be represented by x, the she could determine the distance across the river, d, by applying the trigonometric function.
Tan θ = [tex]\frac{opposite}{adjacent}[/tex]
= [tex]\frac{x}{d}[/tex]
the the distance, d = x ÷ Tan θ
Assume the angle of elevation of the top of the tree is [tex]30^{o}[/tex], and the height of the tree is 10 m, then the distance, d, across the river would be;
d = [tex]\frac{10}{0.5774}[/tex]
= 17.3190
d = 17.32 m

Create the equation of a quadratic polynomial, in standard form, that has zeroes of -5 and 2 and which passes through the point (3,-24).
Answers
9514 1404 393
Answer:
y = -3x^2 -9x +30
Step-by-step explanation:
When a polynomial has a zero at x=p, it has a factor of (x -p). The factors of your quadratic are ...
f(x) = (x +5)(x -2)
At the point x=3, the value of this product is ...
f(3) = (3 +5)(3 -2) = (8)(1) = 8
In order for that value to be -24, it needs to be multiplied by a scale factor of -3. The quadratic you want is ...
y = -3(x +5)(x -2)
y = -3x^2 -9x +30 . . . . . standard form

Step-by-step explanation:
The given parameters are;
The line of symmetry of f(x) = The line of the reflection of g(x) over the y-axis
f(x) = 3·x² + b·x + c
From the given graph of g(x), we have;
The vertex point of g(x) = (-1, 8)
The line of symmetry is the line x = -1
The image of the reflection of (x, y) over the y-axis is (-x, y)
The image of the vertex of g(x) following a reflection across the y-axis is (1, 8)
Therefore;
The line of symmetry of the image of g(x) following a reflection over the x-axis is the line x = 1
The line (axis) of symmetry of a quadratic function is the line x = -b/(2·a), which is a line that always go through the vertex of the parabola
Where;
a = The coefficient of x²
b = The coefficient of 'x'
For f(x) = 3·x² + b·x + c, a = 3, and b = b
Given that f(x) and the image of g(x) have the same line of symmetry, we have;
The line of symmetry of f(x) is x = 1
Therefore, from the formula for the line of symmetry, we have;
x = -b/(2·a)
x = 1
By substitution, we have;
1 = -b/(2·a)
∴ -2·a = b
Given that a = 3, we get;
-2 × 3 = -6 = b
b = -6

A sculptor is planning to make two triangular prisms out of steel. The sculptor will use ABC for the bases of one prism and DEF for the bases of the other prism.
a) is ABC similar to DEF explain
b) suppose the sculptor makes both prisms with the same height. which prism will have a greater volume? how many times greater? show your work
Answers
Answer:
a) yes, they are similar
b) ΔDEF will have a greater area
1.2 times greater (which is the same proportion as 36/30)
Step-by-step explanation:
a) 40/48 = 0.8333
30/6 = 0.8333
Same ratio so they are similar
b) ΔDEF will have a greater area because EF is longer than BC.
area of ΔABC = 1/2(30)(40) = 600 cm²
area of ΔDEF = 1/2(36)(40) = 720 cm²
720/600 = 1.2 x greater

Step-by-step explanation:
I just did it on EDG, got it wrong so i could give you the answer XD
The likelihood that a randomly chosen consumer on plan B would text on the phone the most frequently is 13/23.
What is probability?Probability is a number that expresses the likelihood or chance that a specific event will take place. Both proportions ranging from 0 to 1 and percentages ranging from 0% to 100% can be used to describe probabilities.
According to the given data,
Number of customers on plan B = 13 + 10 = 23
Number of customers on plan B who text = 13
P(text|plan B) = P(text and plan B) / P(plan B),
where P(text and plan B) is the probability of a customer being on plan B and texting, and P(plan B) is the probability of a customer being on plan B, can be used to calculate the likelihood that a randomly chosen customer on plan B will text the most.
So,
P(text|plan B) = 13/23
Therefore, the probability that a randomly selected customer who is on plan B uses the phone most often to text is 13/23.
