Answer:
Lucky for you i'm good at algebra:)
Step-by-step explanation:
Slope: -2/3
Y-intercepts: (0,7)
Answer:
Slope = -1.333/2.000 = -0.667
x-intercept = 21/2 = 10.50000
y-intercept = 21/3 = 7
Step-by-step explanation:
Rearrange:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
y-(-2/3*x+7)=0
Step 1:
Simplify 2/3
Equation at the end of step 1:
y - ((0 -(2/3• x)) + 7) = 0
Step 2: Rewriting the whole as an Equivalent Fraction
Rewrite the whole as a fraction using 3 as the denominator :
7 = 7/1 = 7 · 3 /3
Equivalent fraction : The fraction thus generated looks different but has the same value as the whole
Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator
Adding fractions that have a common denominator :
Adding up the two equivalent fractions
Add the two equivalent fractions which now have a common denominator
Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:
-2x+7·3/3 = 21-2x/3
Equation at the end of step 2:
y-(21-2x)/3=0
Step 3:
Rewriting the whole as an Equivalent Fraction :
Subtracting a fraction from a whole
Rewrite the whole as a fraction using 3 as the denominator :
y=y/1=y·3/3
Adding fractions that have a common denominator :
Adding up the two equivalent fractions
y • 3 - ((21-2x)) 3y + 2x - 21
————————————————— = ————————————

Equation at the end of step

:
3y + 2x - 21
———————————— = 0

When a fraction equals zero :
4.1 When a fraction equals zero ...
Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.
Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.
Here's how:
3y+2x-21
———————— • 3 = 0 • 3
3
Now, on the left hand side, the 3 cancels out the denominator, while, on the right hand side, zero times anything is still zero.
The equation now takes the shape :
3y+2x-21 = 0
Equation of a Straight Line
4.2 Solve 3y+2x-21 = 0
Tiger recognizes that we have here an equation of a straight line. Such an equation is usually written y=mx+b ("y=mx+c" in the UK).
"y=mx+b" is the formula of a straight line drawn on Cartesian coordinate system in which "y" is the vertical axis and "x" the horizontal axis.
In this formula :
y tells us how far up the line goes
x tells us how far along
m is the Slope or Gradient i.e. how steep the line is
b is the Y-intercept i.e. where the line crosses the Y axis
The X and Y intercepts and the Slope are called the line properties. We shall now graph the line 3y+2x-21 = 0 and calculate its properties
Graph of a Straight Line :
Calculate the Y-Intercept :
Notice that when x = 0 the value of y is 7/1 so this line "cuts" the y axis at y= 7.00000
y-intercept = 21/3 = 7
Calculate the X-Intercept :
When y = 0 the value of x is 21/2 Our line therefore "cuts" the x axis at x=10.50000
x-intercept = 21/2 = 10.50000
Calculate the Slope :
Slope is defined as the change in y divided by the change in x. We note that for x=0, the value of y is 7.000 and for x=2.000, the value of y is 5.667. So, for a change of 2.000 in x (The change in x is sometimes referred to as "RUN") we get a change of 5.667 - 7.000 = -1.333 in y. (The change in y is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)
Slope = -1.333/2.000 = -0.667
Geometric figure: Straight Line
Slope = -1.333/2.000 = -0.667
x-intercept = 21/2 = 10.50000
y-intercept = 21/3 = 7

thank u!
Answer:
x = 41
y = 65
z = 107
Step-by-step explanation:
y and 65 are vertically opposite angles. Vertically opposite angles are equal.
y = 65
74 + y + x = 180
74 + 65 + x = 180
139 + x = 180
x = 180 - 139
x = 41
z is the exterior angle, whereas 66 and x are interior angles in a triangle.
Formula : -
Exterior angle = Sum of two interior angles
z = 66 + x
= 66 + 41
z = 107

If 1/3 is equivalent to 33 1/3%, what percent is equivalent to 2/3?
A: 33 2/3%
B: 150%
C: 66 2/3%
D: 65%
Answer:
C 66 2/3%
Step-by-step explanation:
1/3 = 33 1/3%
1/3 = 33 1/3 ∙ 1/100 % means 1/100
1/3 = 100/3 ∙ 1/100 33 1/3= (33∙3+1)/3=100/3
1/3 = 100/300 Reduce
1/3 = 1/3 Check so
1/3 = 33 1/3%
Now 2/3=?%
We know that 2/( 3) = N ∙ 1/100 meaning of percent (%)
2/3 = N/100
200 = 3N
200/3 = N
66.66 =N
Therefore 2/3 = 66 2/3 %

Cómo se resuelve esto?
(2-x)²=36
Answer:
Step-by-step explanation:
You have to factor but we start by simplifying both sides which will be x^2-4x+4=36. Then you subtract 36 from both sides
x^2-4x+4-36=36-36
x2-4x-32
Now that the equation is set up, you can factor
(x+4)(x-8)Set the factors equal to 0
x=-4 or
x=8

The answer to this question
Answer:
113=x
Step-by-step explanation:
seeing as how the sum of all angles in a triangle is 180 degrees, we can get an equation:
28+39+x=180
simplify to get:
67+x=180
subtract 67 from both sides to get your answer:
113=x
Answer:
[tex]x=113[/tex]
[tex]y=67[/tex]
[tex]z=49[/tex]
Step-by-step explanation:
To find x:
We can use the angle sum property of a triangle which states that, The sum of all internal angles of a triangle is always equal to 180°.
Therefore, [tex]28+39+x=180[/tex]
[tex]67+x=180[/tex]
[tex]x=180-67[/tex]
[tex]x=113[/tex]
Now that we know the value of [tex]x[/tex] we can use it to find the value of [tex]y[/tex].
We can see that angle [tex]x[/tex] and [tex]y[/tex] are supplementary which means:
[tex]x+y=180[/tex]
[tex]113+y=180[/tex]
[tex]y=180-113[/tex]
[tex]y=67[/tex]
Now that we know the value of [tex]y[/tex] we can use the angle sum property of a triangle again:
[tex]64+y+z=180[/tex]
[tex]64+67+z=180[/tex]
[tex]131+z=180[/tex]
[tex]z=180-131[/tex]
[tex]z=49[/tex]
under which circumstances will a right angle triangle have a line of symmetry give reasons

A model of a building is 18 inches tall. If the building is really 678 feet tall, how tall is a window that is 1/9 in on the model? Round to the nearest tenth if needed.
Answer:
50.2in or 4.2ft
Step-by-step explanation:
This is a problem about proportions so I generally set up my problems like below. I just set some variable here to make it easier to refer back to the measurements for each. You don't have to do this, I am just showing it for clarity. I will convert everything to inches too. We need to find the real window height.
Mb = model building = 18in
Mw= model window = [tex]\frac{1}{9}[/tex]in
Rb = real building = 678ft = 8136in
Rw = real window = ?
[tex]\frac{Mw}{Mb}[/tex] = [tex]\frac{Rw}{Rb}[/tex]
[tex]\frac{1/9}{18}[/tex] = [tex]\frac{Rw}{8136}[/tex]
[tex]\frac{1}{9*18}[/tex] = [tex]\frac{Rw}{8136}[/tex]
[tex]\frac{1}{162}[/tex] = [tex]\frac{Rw}{8136}[/tex]
[tex]\frac{1*8136}{162}[/tex]= [tex]\frac{8136*Rw}{8136}[/tex]
[tex]\frac{8136}{162}[/tex] = Rw
[tex]\frac{452}{9}[/tex] = Rw
Rw ≈ 50.2in ≈ 4.2ft

Answer:
4x+9=x+15
x = 2
Step-by-step explanation:
Let's solve this equation I just made:
4x + 9 = x + 15
Subtract 9 from each side:
4x = x + 6
Subtract x from each side:
3x = 6
Divide each side by 3:
x = 2
