2x+5y =5
Answer:
(5,-1) or x=5 y=-1
Step-by-step explanation:
I used the substitution method to solve this!
1. Pick one of your equations and solve for one of the variables. I chose the first equation and solved for x.
x-2y=7
(Move the -2y to the other side of the equation in order to get the x by itself. You do the opposite, so it becomes +2y.)
x=2y+7
2. Now take your second equation and plug in what you got for x into the x variable.
2(2y+7)+5y=5
(Multiple 2 by everything inside of the parentheses.)
4y+14+5y=5
(We want to get the y by itself, so move the 14 to the other side.)
4y+5y=-14+5
(Combine all the like terms.)
9y=-9
(Divide the 9 from the y. What you do to one side you must do to the other.)
y=-1
3. Since you have one variable solved for. Now take the first equation and plug in your y.
x-2(-1)=7
(Multiple -2 by -1)
x+2=7
(Move the 2 to the other side in order to get the x by itself.)
x=5
4. If needed, plug in your x and y values into the equations in order to check your answer.
Hope this could help!

6.Line 2x -2y = 6 is transformed by a dilation a scale factor of 2 and centered at the (4, 1). What is the equation of the line after the dilation?
9514 1404 393
Answer:
y = x - 3
Step-by-step explanation:
The given point is on the line. The dilation stretches the line along its length, but does not change its equation. In slope-intercept form the equation of the given line, and that of the dilated line, is ...
y = x - 3
In standard form, it is ...
x - y = 3
In the given form, it is ...
2x -2y = 6

30. Scott purchased a painting in 2006 for $1,250. Since then, its value has increased by 6% each year. Use an exponential function find the value of the painting in 2017.
Step-by-step explanation:
28. a=422000 (1+12%)^8
=1044856.46
29 a=13000 (1+15%)^-5
=6463.29

Answer:
radius: 3 units <----> Circumference: 18.84 units
Diameter: 12 units <----> Circumference: 37.68 units
Diameter: 36 units <----> Circumference: 113.04 units
Radios: 5 unites <----> Circumference: 31.4 units
Step-by-step explanation:
How I got the answers for the radiuses:
3 (this is only half the diameter so if you do 3 x 2 you will get the diameter.)
3 x 2 = 6
C = pi x d
C = 3.14 x 6
C = 18.84 [this is the first radios]
5 (this is only half the diameter so if you do 5 x 2 you will get the diameter.)
5 x 2 = 10
C = pi x d
C = 3.14 x 10
C = 31.4 [this is the second radios]
How I got the diameters:
12 (this is the full diameter so we do not have to multiply it by 2)
C = pi x d
C = 3.14 x 12
C = 37.68 [this is the first Diameter]
36 (this is the full diameter so we do not have to multiply it by 2)
C = pi x d
C = 3.14 x 36
C = 113.04 [this is the second Diameter]

What is the y-intercept for the following:
5x – 7y = - 14
Answer:
5x-7y+14=0
y= -14/5+7/5y
Step-by-step explanation:
Answer:
y-intercept = 2
Step-by-step explanation:
Write in slope y-intercept form
y = mx + b
5x - 7y = -14
-7y = -5x - 14
Divide the equation by (-7)
[tex]\frac{-7y}{-7}=\frac{-5x}{-7} -\frac{14}{-7}\\\\y = \frac{5}{7}x+2[/tex]
A phone company charges a $35 fee for signing up for their service plan and $40 for each month of service. Write a linear equation to model this situation.
Will give brainliest please take seriously
Answer:
y = 40x + 35
Step-by-step explanation:
Let x represent each month of service in the equation
Since it is $40 for each month, the price for each month can be represented by 40x.
The $35 fee will represent the y intercept, and will be added to 40x in the equation.
Put this together in the equation y = mx + b
y = 40x + 35
So, the linear equation to model the situation is y = 40x + 35

The Soup Shack usually makes tomato soup with 999 tomatoes for every 121212 bowls of soup. Today, they made 888 bowls of soup with 666 tomatoes.
Answer:
Same quanitity.
Step-by-step explanation:
The Soup Shack usually makes tomato soup with 9 tomatoes for every 12 bowls of soup.
Today, they made 8 bowls of soup with 6 tomatoes.
We need to compare today's soup to the usual recipe.
For 9 tomatoes for every 12 bowls of soup = [tex]\dfrac{9}{12}=\dfrac{3}{4}[/tex]
For 8 bowls of soup with 6 tomatoes = [tex]\dfrac{6}{8}=\dfrac{3}{4}[/tex]
It means we can see that both the soup has the same quantity. Hence, this is the required solution.

Mixed numberMixed number is the combination of the whole number and the fraction number. The whole and the part of the whole combined can be expressed as a mixed numbers.
Now the given mixed number has to be divided. This number can be divided by converting into the proper fraction numbers. Let I is the result when the two numbers are divided. Thus,
[tex]x=8\dfrac{1}{2} \div 2\dfrac{2}{3} \\ [/tex]
To solve this convert the mixed numbers into the fraction number. For this multiply the denominator to the whole number and then add in the numerator. Thus,
[tex]x=\dfrac{16+1}{2} \div \dfrac{6+2}{3} \\ x=\dfrac{17}{2} \div \dfrac{8}{3} \\ [/tex]
Convert the divide sign into the multiply sign by changing the numerator to the denominator of one of the fraction.
[tex]x=\dfrac{17}{2}\times \dfrac{3}{8} \\ x=\dfrac{51}{16}\\[/tex]
As 16 can divide the number 51 in 3 times with reminder 3. Thus the mixed number for the above fraction can be written as,
[tex]x=3\dfrac{3}{16}[/tex]
Thus the result of the division of the two mixed number is [tex]3\dfrac{3}{16}[/tex].

Triangle ABC is a right triangle.
m∠A=5x°
m∠B=(3x−4)°
m∠C=90°
What is the value of x?
Answer:
11.75
Step-by-step explanation:
5x+3x-4+90 = 180
(the sum of interior angles of a triangle is always 180
8x-4+90 = 180
+4 +4
8x+90=184
-90 -90
8x=90
/8 /8
x = 11.75
The value of x from the given right triangle ABC is 11.75°.
What is angle sum property of a triangle?Angle sum property of triangle states that the sum of interior angles of a triangle is 180°.
Given that, triangle ABC is a right triangle with m∠A=5x°, m∠B=(3x−4)° and m∠C=90°.
Here, m∠A+m∠B+m∠C=180°
5x°+(3x−4)°+90°=180°
5x°+(3x−4)°=90°
8x°-4°=90°
8x°=94°
x=94/8
x=11.75°
So, 5x= 5×11.75 =58.75° and (3x−4)°=3×11.75-4
= 35.25-4
= 31.25°
Therefore, the value of x is 11.75°.
