Step-by-step explanation:
3x + 4y = 7, 8x + 5y = 12. The value of x and y is
13, 20
20, 13
13/17, 20/17
20/17, 13/17
Answer:
13/17, 20/17
Step-by-step explanation:
3x + 4y = 7 --- Equation 1
Equation 1×5:
15x + 20y = 35 --- Equation 2
------------------------------------------------------------------------------------------------------------
8x + 5y = 12 --- Equation 3
Equation 3×4:
32x + 20y = 48 --- Equation 4
------------------------------------------------------------------------------------------------------------
Equations 4-2:
32x + 20y - 15x - 20y = 48 - 35
17x = 13
x = [tex]\frac{13}{17}[/tex]
Substitute x = [tex]\frac{13}{17}[/tex] into Equation 1:
3x + 4y = 7
3([tex]\frac{13}{17}[/tex]) + 4y = 7
[tex]\frac{39}{17}[/tex] + 4y = 7
4y = 7 - [tex]\frac{39}{17}[/tex]
= [tex]\frac{119}{17}[/tex] - [tex]\frac{39}{17}[/tex]
= [tex]\frac{80}{17}[/tex]
y = [tex]\frac{80}{17}[/tex] ÷ 4
y = [tex]\frac{20}{17}[/tex]
Thus, x = [tex]\frac{13}{17}[/tex], y = [tex]\frac{20}{17}[/tex].
( [tex]\frac{13}{17}[/tex], [tex]\frac{20}{17}[/tex])

Write the simplest polynomial function for each set of zeros
Zeros = 8,-10, 1,
PLEASEEEEE HELPPPPPPPPPP
9514 1404 393
Answer:
p(x) = x^3 +x^2 -82x +80
Step-by-step explanation:
If a polynomial function has a zero at x=a, then (x -a) is a factor. Your list of zeros means the factors are ...
p(x) = (x -8)(x +10)(x -1) . . . . . . . . factored form
When this is multiplied out, it becomes ...
p(x) = x^3 +x^2 -82x +80 . . . . . . standard form
_____
The factored form can be multiplied out using the distributive property.
= ((x(x +10) -8(x +10))(x -1)
= (x^2 +10x -8x -80)(x -1)
= (x^2 +2x -80)x -(x^2 +2x -80)
= x^3 +2x^2 -80x -x^2 -2x +80
= x^3 +x^2 -82x +80
Write an equation of the line in slope-intercept form
(-1,0) (-5,0)
Answer:
if there are no typos, line is y=0
Step-by-step explanation:
slope intercept form is y=mx+b
m= slope
b= y intercept
slope is found by y2-y1 / m2-m1
so using the points (-1, 0) and (-5, 0)
(0-0) / (-5 - -1)
= 0/ -4
= 0
m=0
y=0x+b
plug in a point to find b
0=0*-1 +b
b=0
The line is just y=0

Can someone write an equation out of X= -4 Y= -8 Z= 3
Answer:
2y + 4z = x
Step-by-step explanation:
Given
[tex]x = -4[/tex]
[tex]y = -8[/tex]
[tex]z = 3[/tex]
Required
Write an equation that which is true for the above parameters
This question will be answered using trial by error method and the solution is not limited to one equation.
One equation that matches the values above is:.
[tex]2y + 4z = x[/tex]
To check:
Substitute the values of x, y and z in the above equation.
[tex]2y + 4z = x[/tex]
[tex]2 * -8 + 4 * 3 = -4[/tex]
[tex]-16 + 12 = -4[/tex]
[tex]-4 = -4[/tex]
Hence,
Because both sides of the equation are one and the same (-4), [tex]2y + 4z = x[/tex] is true for the above values of x, y and z.
v= u + at
u=2 a= -5 t=1 half
What’s the value of v?
Answer:
Prime number
Step-by-step explanation: because it doesn't have a value so yeah its a prime number.
Answer:
V = 0.5
Step-by-step explanation:
V = u + at
If U = 2, a = -5, and t = 1/2, then you can replace these in the equation to make the equation: V= 2 + (-5 x 1/2)
Solve the parenthesis first. -5 times 1/2 is -2.5.
Now the equation is V= 2 + -2.5
Simplifying that even more, 2 + -2.5 is 0.5
Therefore, V = 0.5

Jordan is another employee at the same coffee shop. He has worked there longer than Gabe and earns 3 more per hour than Gabe. How much money will he earn after the following hours: 4, 8 ,12 and 16
Answer:
1.
- Gabe earns 13.5 per hour
2.
x ------------------ 4 ---- 8 --------- 12 ------ 16
Earnings ----- 57 ---- 111 ------- 165------ 219
Step-by-step explanation:
See attachment for complete question
Solving (a): Gabe's earnings per hour,
To do this, we simply calculate the slope (m) of the table.
[tex]m = \frac{y_2 - y_1}{x_2- x_1}[/tex]
Where
[tex](x_1,y_1) = (3,40.5)[/tex]
[tex](x_2,y_2) = (6,81.0)[/tex]
[tex]m = \frac{y_2 - y_1}{x_2- x_1}[/tex]
[tex]m = \frac{81 - 40.5}{6 - 3}[/tex]
[tex]m = \frac{40.5}{3}[/tex]
[tex]m = 13.5[/tex]
Hence, Gabe earns 13.5 per hour
Solving (b): Jordan earnings
First, we calculate the equation of Gabe's table using:
[tex]y - y_1 = m(x - x_1)[/tex]
Where
[tex]m = 13.5[/tex] and [tex](x_1,y_1) = (3,40.5)[/tex]
[tex]y - 40.5 = 13.5(x - 3)[/tex]
[tex]y - 40.5 = 13.5x - 40.5[/tex]
[tex]y = 13.5x[/tex]
If Jordan earns 3 more per hour than Gabe, then: Jordan's equation would be;
[tex]y = 13.5x + 3[/tex]
When x = 4
[tex]y = 13.5*4 + 3 = 54 + 3 = 57[/tex]
When x = 8
[tex]y = 13.5*8 + 3 = 108 + 3 = 111[/tex]
When x = 12
[tex]y = 13.5*12 + 3 = 162 + 3 = 165[/tex]
When x = 16
[tex]y = 13.5*16 + 3 = 216 + 3 = 219[/tex]

Kristy asks Lonnie to think of a number , Add 3 to it, multiply the sum by 2, and then subtract 6. Let n stand for lonnie's starting number. Which expression represents Lonnie's final number?
Answer:
2(n+3) - 6 = 2n
Step-by-step explanation:
Let n stand for lonnie's starting number.
Kristy asks to add 3 to the number. It will become (n+3)
Now he ask to multiply the sum by 2. It will become 2(n+3).
Finally, he ask to subtract 6. It will become 2(n+3) - 6
The expression is : 2(n+3) - 6.
We can simplify it as follows :
= 2n+6-6
= 2n
Hence, the required expression is 2n.

Consider the function f(x) = 3x - 2 and the function g(x), which is represented by the table below. Which of the following statements about f(x) and g(x) is true? Select all that apply.
1. The slope of f(x) is smaller than the slope of g(x)
2. The lines represented by f(x) and g(x) are parallel.
3. The line represented by f(x) crosses the x-axis to the right of the line represented by g(x).
4. The y-intercept of f(x) is smaller than the y-intercept of g(x).
5. The values of f(x) and g(x) are the same at x = 3
Answer:
4. 5. 3. are correct im pretty sure
Step-by-step explanation:
Statements 1, 2, and 3 about f(x) and g(x) are "true".
What are the functions?The function is defined as a mathematical expression that defines a relationship between one variable and another variable.
Consider the function f(x) = 3x - 2 and the function g(x), which is represented by the table below.
x : 1 3 5 7 9
g(x): 3 7 11 15 19
Here the slope of the function g(x) is 2.
This means statements 1 and 2 are false because slopes are different.
To compare the position of the lines at the x-axis, you can evaluate the function at x=0. f(0) = 3×0 - 2 = -2 and g(0) = -1.
Since g(0) is less than f(0), the line represented by g(x) crosses the x-axis to the right of the line represented by f(x). So, statement 3 is true.
The y-intercept of f(x) is -2, while the y-intercept of g(x) is 1. So, statement 4 is true.
To compare the values of f(x) and g(x) at x=3, you can evaluate the functions at x=3. f(3) = 3×3 - 2 = 7 and g(3) = 7. So, the values of f(x) and g(x) are the same at x=3. So, statement 5 is true.
Therefore, the true statements are 2, 3, and 4.

The 8th Grade wants to raise money for a field trip that costs $800. 15 students are in charge of fundraising. What is the minimum amount of money they each have to raise to achieve their goals (if they each raise the same amount of money)?
Answer: $54.35
Step-by-step explanation:
If each one of the 15 students raises the same amount, let's define this amount by the variable X, then the total amount they will collect is 15 times X, or:
15*X
And the minimum amount they need to collect is $800
Then we will have the inequality:
15*X ≥ $800
Now we can divide both sides by 15 to get the minimum amount that each student needs to raise:
(15*X)/15 ≥ $800/15
X ≥ $54.33...
Where we should round up the right number to $54.35, because we can not have a $0.0333... and if we round down, they would collect less than $800.
Then the inequality is:
X ≥ $54.35
This means that the minimum amount that each one of the 15 students needs to collect is $54.35

Anybody know this question
Here as by the given information ,
♦ sinA = Opposite/Hypotenuse
♦ cosA = Adjacent/Hypotenuse
♦ TanA = Opposite/adjacent
So here we need to find the same for angle B so we need to use the same formulas for angle B also .
→ sinB = Opposite/Hypotenuse = 12/13
→ cosB = Adjacent/Hypotenuse = 5/13
→ tanB = Opposite/Adjacent = 12/5
