on your own paper graph the following equations. describe the graphs and give a solution to the system of equations -2x - 5y = 20 y = 4/5 x + 2
Answer:
Please check the explanation.
Step-by-step explanation:
Given the system of equations
[tex]\begin{bmatrix}-2x-5y=20\\ y=\frac{4}{5}x+2\end{bmatrix}[/tex]
Please check the attached graph.
On the attached diagram:
The blue line represents the line -2x - 5y = 20
The red line represents the line y = 4/5x + 2
It is clear from the graph that both the graphs meet or intersect each other at the point (-5, -2).
In other words,
(x, y) = ( -5, -2) is the point of intersection of the two lines.
We know that the point of intersection of the two lines is the solution of the system of equations.
Therefore, the solution to the system of equations will be:
(x, y) = ( -5, -2)
The solution to the system of equations using the elimination method:
Given the system of equations
[tex]\begin{bmatrix}-2x-5y=20\\ y=\frac{4}{5}x+2\end{bmatrix}[/tex]
Arrange equation variables for elimination
[tex]\begin{bmatrix}-2x-5y=20\\ -\frac{4}{5}x+y=2\end{bmatrix}[/tex]
Multiply -2x - 5y = 20 by 2: -4x-10y=40
Multiply y = 4/5x + 2 by 5: -4x+5y=10
so
[tex]\begin{bmatrix}-4x-10y=40\\ -4x+5y=10\end{bmatrix}[/tex]
now subtracting
[tex]-4x+5y=10[/tex]
[tex]-[/tex]
[tex]\underline{-4x-10y=40}[/tex]
[tex]15y=-30[/tex]
solve 15y = -30 for y
[tex]15y=-30[/tex]
Divide both sides by 15
[tex]\frac{15y}{15}=\frac{-30}{15}[/tex]
[tex]y=-2[/tex]
For -4x-10y=40, plug in y = -2
[tex]-4x-10\left(-2\right)=40[/tex]
[tex]-4x+20=40[/tex]
simplify
[tex]-4x=20[/tex]
divide both sides by -4
[tex]\frac{-4x}{-4}=\frac{20}{-4}[/tex]
Simplify
[tex]x=-5[/tex]
Therefore,
The solution to the system of equations will be:
(x, y) = ( -5, -2)

Answer:
D
Step-by-step explanation:
The statements that is needed in order to prove these triangles are congruent using SSS is; AB ≅ DE
What is the congruent triangle?Two triangles are said to be congruent if the length of the sides is equal, a measure of the angles are equal and they can be superimposed.
ASA or Angle-Side-Angle stated that If two corresponding interior angles of two triangles and the included sides are congruent, the triangles are congruent.
SSS or Side-Side-Side postulate state that If three corresponding sides of two triangles are congruent, the triangles are congruent.
In a triangle BCA≅ EFD
three corresponding sides must be equal.

Solve please
Answer:
(2,-2)
Step-by-step explanation:
Answer:
x = 2, y = -2
Step-by-step explanation:
This means that [tex]-3x + 4 = 4x - 10[/tex]
Now, you just have to solve the equation
[tex]-3x + 4 = 4x - 10\\\\[/tex]
add 3x to both sides
[tex]4 = 7x - 10[/tex]
add 10 to both sides
[tex]14 = 7x[/tex]
divide both sides by 7
[tex]x = 2[/tex]
Substitute this into the equation [tex]y = -3x + 4[/tex]
[tex]y = -3(2) +4\\y = -6 + 4[/tex]
[tex]y = -2\\[/tex]
how would you rewrite the expression 4 times the sum of 14 and 26
Answer:
4 (14+26)
Step-by-step explanation:
in order to multiple a sum you must add the 2 numbers to get the sum then multiply.
in order to do so you must add Parentheses.
(14 + 26)
then you multiply
4 ( 14 + 26 )
Answer:
4(14+26)
Step-by-step explanation:
Here you go! 4 times the SUM of 14 and 26 would mean, you have the addition problem now multiply that by 4 but don't solve the addition problem.

Ben is paid £8.50 per hour.
If he works for more than 8 hours in a day, he is paid
overtime for the additional hours at a rate of 1.4 times his
normal rate of pay.
Yesterday, Ben worked for 11 hours.
How much money did he earn?
Answer:
£103.70
Step-by-step explanation:
Payment per hour = £8.50
Overtime payment = 1.4 × 8.50
= £11.90
Ben worked for 11 hours.
Normal time = 8 hours
Overtime = 3 hours
Total earnings = (8 hours × 8.50) + (3 hours × 11.90)
= £68 + £35.7
= £103.70
Ben earned £103.70 for working for 11 hours

Alexis divided a 5/12 pound bag of apples among her five friends. How many pounds of apples did each friend receive?
Answer: 1 /12 pounds each
Step-by-step explanation:
Alexis has a 5/12 pound bag of apples and 5 friends to divide them amongst.
The number of pounds each friend receives is the number of pounds Alexis has divided by the number of friends she has:
= 5/12 ÷ 5
= 5/12 * 1/5
= 5 / 60
Take the fraction to the lowest form by dividing by 5:
= 1 / 12
Hint: When dividing a fraction by a number, you can instead multiply that fraction by the inverse of that number.
