Answer:
the domain represents all the x values and range represents all the y value
In a function y=mx+b ( linear equation), the problem is giving the y values so plug in the value of each (y) in the equation to get x.
example: the range is : { 2,4,6} find the domain in the function y=x+1
y=x+1 take value 2
2=x+1
x=1 when y=4 then x=3when y=6 then x=5the domain is { 1,3,5}this goes for linear equation

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!
A small gecko is 3/4 inch long. A larger gecko is 12 2/3 times as long. How long is the larger gecko
Answer:
[tex]9\frac{1}{2}[/tex]
Step-by-step explanation:
Length of small gecko =[tex]\frac{3}{4} \:inches[/tex]
Length of larger gecko = [tex]12\frac{2}{3} \times\: length \: of\: smaller\: gecko[/tex]
= [tex]12\frac{2}{3} \times \frac{3}{4} \\\\\mathrm{Convert\:mixed\:numbers\:to\:improper\:fractions}:\quad 12\frac{2}{3}=\frac{38}{3}\\\frac{38}{3}\times \frac{3}{4}\\\\Multiply\:fractions\\=\frac{38\times \:3}{3\times \:4}\\\\\mathrm{Cancel\:the\:common\:factor:}\:3\\=\frac{38}{4}\\\\\mathrm{Cancel\:the\:common\:factor:}\:2\\=\frac{19}{2}\\\\\mathrm{Convert\:improper\:fractions\:to\:mixed\:numbers}:\\\quad \frac{19}{2}=9\frac{1}{2}[/tex]
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]

Step-by-step explanation:
(-64=)-8+6=-2+(-16=)-4-3=5
Answer:
50Step-by-step explanation:
(6 + √-64) (3 - √-16)
= (6 + 8i) (3 - √-16)
= (6 + 8i) (3 - 4i)
= (6 * 3 - 8 (-4)) + (6(-4) + 8 * 3)i
= 6 * 3 - 8(-4) = 50
= 6(-4) + 8*3 = 0
= 50 + 0i
= 50
2. Sketch the graph: 4y – 3x = 12.
Answer:
see below
Step-by-step explanation:
A graphing calculator is useful for this.
__
To find the x-intercept, set y=0 and solve for x:
0 -3x = 12
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.

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 )
Does anyone know how to do any of these problems? My notes are no help and none of my classmates know what to do either.
Answer:
17) 40°
18) 3x+22
19) (1,-4.5)
20) (-1,-2.5)
Step-by-step explanation:
17) 99=59=40°
18) 2x+7+x+15=3x+22
19) 6-(-8)=14
14/2=7
-8+7=1
-2-(-7)=5
5/2=2.5
-2-2.5=-4.5
midpoint = (1,-4.5)
20) 6-(-8)=14
14/2=7
-8+7=-1
5-(-10)=15
15/2=7.5
-10+7.5=-2.5
Midpoint = (-1,-2.5)

Step-by-step explanation:
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

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

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
