Answer:
([ 1 ], [ 2 ], [ 3 ])
Step-by-step explanation:
y – 3z = -7; z = 3 => y = 2
x + 4y +z = 12 => x + 4(2) + 3 = 12 => x = 1

An input-output machine generates the information below
a- Find the values to fill in the table for variables a and b
b- write up a rule that describes the relationship between the input output.
c- what is the value of the output and input in 20?
d- what is the value of the input when the output is 77.
Using a linear function, we have that:
a) The values are: a = 11 and b = 5.
b) The rule is:
[tex]y = 3x + 2[/tex]
c) The value of the output is 62.
d) The value of the input is 25.
The equation of a linear function is given by:
[tex]y = mx + b[/tex]
In which
m is the slope, which is the rate of change.b is the y-intercept, which is the initial value.First, we are going to solve item b to find the rule, then we solve other items.
Item b:
In the table, we have two points: (1,5) and (2,8).
The slope is given by change in y divided by change in x, thus:
[tex]m = \frac{8 - 5}{2 - 1} = 3[/tex]
Then
[tex]y = 3x + b[/tex]
Point (1,5) means that when [tex]x = 1, y = 5[/tex], and this is used to find b.
[tex]5 = 3(1) + b[/tex]
[tex]b = 2[/tex]
Thus, the rule is:
[tex]y = 3x + 2[/tex]
Item a:
a is the value of y when x = 3, thus:
[tex]y = a = 3(3) + 2 = 11[/tex]
Thus, a = 11.
b is the value of x when y = 17, thus:
[tex]3b + 2 = 17[/tex]
[tex]3b = 15[/tex]
[tex]b = 5[/tex]
The values are: a = 11 and b = 5.
Item c:
The value of the output is y when x = 20, thus:
[tex]y = 3(20) + 2 = 60 + 2 = 62[/tex]
Thus, the value of the output is 62.
Item d:
The value of the input is x when y = 77, thus:
[tex]3x + 2 = 77[/tex]
[tex]3x = 75[/tex]
[tex]x = \frac{75}{3}[/tex]
[tex]x = 25[/tex]
The value of the input is 25.

Answer:
? =64.62306
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
cos theta = adjacent side / hypotenuse
cos ? = 3/7
Taking the inverse cos of each side
cos ^-1 ( cos ? ) = cos ^-1 (3/7)
? =64.62306
Answer:
The angle is approximately 23°
Step-by-step explanation:
let the angle be ∆
using trigonometrical identity,
tan ∆=3/7
tan∆=0.4286
∆=tan^-1(0.4286)
∆=23.19°

Ben wants to have his birthday at the bowling alley with a few of his friends, but he can spend no more than $80. The bowling alley charges a flat fee of $45 for a private party and $5.50 per person for shoe rentals and unlimited bowling. Write an inequality that represents the total cost of Ben's birthday for p people given his budget. Use your inequality to solve for how many people Ben can pay for (including himself) while staying within the limitations of his budget? *
Answer:
He can pay for 5 friends plus himself while staying within the budget.
Step-by-step explanation:
No parents are allowed in.
45 + 5.5p = 80 80-45=35 5.5p = 35 35/5.5 = 6.4
So he can pay for himself plus 5 people, and probably a drink.

Answer:
x = 8
x = 21/14
x = 8
x = 15/21
x = 1/4
x = 7
Step-by-step explanation:
(For all instances of number, let it be x)
Double the sum of a number and 15. The result is the same as the product of 23 and the number.
2x + 15 = 23 + x
2x - x + 15 = 23 + x - x
x + 15 = 23
x + 15 - 15 = 23 - 15
x = 8
Multiply a number by 15 and add 2. The result is the same as the sum of 23 and the number.
15x + 2 = 23 + x
14x + 2 = 23
14x = 21
x = 21/14
Double a number and add 15. The result is the same as the sum of 23 and the number.
2x + 15 = 23 + x
x + 15 = 23
x = 8
Double a number and add 15. The result is the same as the product of 23 and the number. (This time we will move the x to the other side as the right side has a larger x than the left side)
2x + 15 = 23x
15 = 21x
x = 15/21
Multiply a number by 15 and add 2. The result is the same as the product of 23 and the number.
15x + 2 = 23x
2 = 8x
2/8 = x
x = 1/4
Double the sum of a number and 15. The result is the same as the sum of 23 and the number.
2(x + 15) = 23 + x
2x + 30 = 23 + x
x + 30 = 23

[tex]\\ \sf\longmapsto cos\Theta=\dfrac{12}{24}[/tex]
[tex]\\ \sf\longmapsto cos\Theta=\dfrac{1}{2}[/tex]
Option C
The value of the cosine for the given triangle XZW will be ( 12 / 24 ). the correct option is C.
What are trigonometric functions?The trigonometric functions in mathematics are real functions that connect the right-angled triangle's angle to the ratios of its two side lengths. They are extensively utilized in various geosciences, including navigation, and solid mechanics.
Trigonometry is the branch of mathematics that set up a relationship between the sides and angle of the right-angle triangles.
The cosine ratio will be calculated by first calculating the perpendicular WZ.
WZ = 12 x tan60
WZ = 12 x √3
WZ = 12√3
Then calculate the hypotenuse of the triangle.
XZ² = 20.78² + 12²
XZ² = 430+ 144
XZ² = 574
XZ = 24
The cosine ratio will be calculated as:-
cosФ = Base / hypotenuse = 12 / 24.
Therefore, the value of the cosine for the given triangle XZW will be ( 12 / 24 ). the correct option is C.

If 1llm, find the value of y
Answer:
y = 70°
Step-by-step explanation:
4x - 50 and 2x + 30 are equal, because they are corresponding angles
4x - 50 = 2x + 30
4x = 2x + 80
2x = 80
x = 40°
The angle below 2x + 30 = y, because they are vertical angles
Since we know what x is, we can substitute x from 2x + 30
And since two angles that take up a line are 180°, we can add them
2(40) + 30 + y = 180
80 + 30 + y = 180
110 + y = 180
y = 180 - 110
y = 70

a baker is making cupcakes. he has 36 pounds of dough. each cupcake is made from ⅙ pound of dough. how many cupcakes can be made?
explain with answer
Answer:
First you have to understand a one cupcake has 1/6 pound of dough.
Then to calculate the number of cupcakes, divide the total 36 pounds of dough by a 1/6 pound.
36/(1/6)
= 36 ×(6/1)
= 216 cupcakes
Answer: 216 cupcakes can be made
Step-by-step explanation:
Given information
36 pounds of dough in total
⅙ pound of dough per cupcake
Set variables
Let x be the number of cupcakes that could be made
Set equations from given information
Total = unit × number
36 = (1/6) × x
Multiply 6 on both sides to isolate [x] variable
36 × 6 = (1/6) × x × 6
216 = 1 × x

6x + 2 - 2 = - 10 - 2
Simplify
6x = - 10 - 2
Simplify the arithmetic:
6x = - 12
Then Isolate x:
6x = - 12
Divide both sides by 6:
(6x)/6 = - 12/6
Simplify the fraction:
x = - 12/6
Find the greatest common factor of the numerator and denominator:
x = (- 2 × 6)/(1 ×6)
