10v-3v=35 what is the answer to this.
answer is v=5
Step-by-step explanation:
10v-3v=7v
7v=35
v=35/7
v=5
Answer: [tex]v=5[/tex]
Simplify both sides of the equation
[tex]10v+-3v=35[/tex]
[tex](10v+-3v)=35[/tex] (Combine Like Terms)
[tex]7v=35[/tex]
Divide both sides by 7
[tex]7v/7=35/7\\v=5[/tex]

Solve: - (g+ 12) = 5(9 - 12)
Answer:
-27
Step-by-step explanation:
(g+ 12) = 5(9 - 12)
g = 45 - 60 - 12
g = - 27
Answer:
g = 3
Step-by-step explanation:
- (g+ 12) = 5(9 - 12) (remove parentheses by distributive property. See attached for reference)
g(-1) + 12(-1) = 9(5) -12(5)
-g - 12 = 45 - 60
-g - 12 = -15 (add 12 to both sides)
-g = -15 + 12
-g = -3 (multiply both sides by -1)
g = 3

15 - 2(3 - 2x) = 46
Answer:
[tex]9.25[/tex]
Step-by-step explanation:
So we have the equation:
[tex]15-2(3-2x)=46[/tex]
First, distribute the -2:
[tex]15-2(3)-2(-2x)=46[/tex]
Multiply:
[tex]15-6+4x=46[/tex]
Subtract:
[tex]9+4x=46[/tex]
Subtract 9 from both sides:
[tex]4x=37[/tex]
Divide both sides by 4:
[tex]x=37/4=9.25[/tex]
And we're done!

An object is translated by (x-2, y-6). If one point in the pre-image has the coordinates (-3, 7,) what would be the coordinates of this image
Answer:
(- 5, 1 )
Step-by-step explanation:
Given the translation rule
(x, y ) → (x - 2, y - 6 )
This means subtract 2 from the original x- coordinate and subtract 6 from the original y- coordinate, that is
(- 3, 7 ) → (- 3 - 2, 7 - 6 ) → (- 5, 1 )

Step-by-step explanation:
Solve for x. 4x+7y+5xy=0
Answer:
x = -7y/(4 +5y)
Step-by-step explanation:
You can treat y as though it were a constant. As in any 2-step linear equation, you separate the variable term(s) from the constant term, then divide by the coefficient of the variable.
4x +5xy = -7y . . . . . subtract 7y
x(4 +5y) = -7y . . . . . factor out x, so we can see its coefficient
x = -7y/(4 +5y) . . . . divide by the coefficient of x

x = -4 . . . . . . divide by -3
To find the y-intercept, set x=0 and solve for y:
4y - 0 = 12
y = 3 . . . . . . divide by 4
Plot the x- and y-intercepts on their respective axes and draw a line through them.
find the distance between each pair of points (-6,-5) (2,0)
Answer: The distance is about 9.43
Step-by-step explanation:
To find the distance between these numbers find the difference in the x and y values then square them and add them together and finally find the square root of the number you got after adding them.
-5 - 0 = -5
-6 - 2 = -8
-5^2 + -8^2 = d^2 where d is the distance
25 + 64 = d^2
89 = d^2
d = [tex]\sqrt{89}[/tex]
d= 9.43

the length of segment HJ if H lies at (-1,7) and J lies at (8,-5)
Answer:
HJ = 15Step-by-step explanation:
To get the length of segment HJ if H lies at (-1,7) and J lies at (8,-5), we will use the formula for calculating the distance between two points as shown;
D = √(x₂-x₁)²+(y₂-y₁)²
From the coordinates x₁ = -1, y₁ = 7, x₂ = 8, y₂ = -5
HJ = √(8-(-1))²+(-5-7)²
HJ = √(8+1)²+(-12)²
HJ = √81+144
HJ = √225
HJ = 15
Hence the length of segment HJ is 15 units
