For khan academy. Need help . Explain if you can
Answer:
y = 2/3x + 1.5
Step-by-step explanation:
The Formula for that is
y = mx + b
m = slope
b = y -intercept
so to find the slope I would do y/x or rise over run
So your slope is 2/3 ( it goes up 2 and right 3 times)
Since the line is going up and not down, it is a positive slope
y = 2/3x + b
we need to find where the line crosses the vertical / y-axis and it's at the point.... (0,1.5)
y = 2/3x + 1.5
Hope this helped a little!

Which of the following statements is true of the diagram?
Answer:
option 2
Step-by-step explanation:
QR = 15 ( triangle is a 8- 15- 17 Pythagorean triple )
cosP = [tex]\frac{PR}{PQ}[/tex] = [tex]\frac{8}{17}[/tex] ≠ [tex]\frac{8}{15}[/tex]
tanQ = [tex]\frac{PR}{QR}[/tex] = [tex]\frac{8}{15}[/tex] ≠ [tex]\frac{15}{8}[/tex]
sinP = [tex]\frac{QR}{PQ}[/tex] = [tex]\frac{15}{17}[/tex] ≠ [tex]\frac{8}{17}[/tex]
cosQ = [tex]\frac{QR}{PQ}[/tex] = [tex]\frac{15}{17}[/tex] ← correct statement
Answer:
its the cos q = 15/17
Step-by-step explanation:
cos q = 15 (adjacent) / 17 (hypothenuse)

1. multiply and divide(left to right)-1/6
=-1/6+4/5
2.multiply and divide(left to right)4/5
=-1/6+4/5
3. add and subtract(left to right)-1/6+4/5=19/30
=19/30
simplify the equations below
Answer:
Problem 1: 1/64x^8
Problem 2: y^8/9x^2
Step-by-step explanation:
In the first problem, you first need to multiply the -2 exponent to everything in the parenthesis. This is equal to 1/64x^4*-2, simplified to be 1/64x^-8. Finally you simplify the x to 1/64x^8.
For the second problem, you do the same in the first one, getting x^-2/9y^4*-2. This can be simplified to be 3x^-2/y^-8. Finally you make sure there is no negative exponents, so you do y^8/9x^2.
Answer:
1/64x^8 and y^8/9x^2
Step-by-step explanation:
hope this helps have a good night :)
A number plus 17 is 25 algebraic expression
Answer:
x + 17 = 25
Step-by-step explanation:
x is "a number" and you just add it to 17. (Also the answer would be 8 if you need to solve it too)
The algebraic expression is x + 17 = 25 and the number is 8 if the number plus 17 is 25.
What is an expression?It is defined as the combination of constants and variables with mathematical operators.
We have:
A number plus 17 is 25 algebraic expressions:
Let x be the number:
x + 17 = 25
After solving:
x = 25 - 17
x = 8
Thus, the algebraic expression is x + 17 = 25 and the number is 8 if the number plus 17 is 25.

Brandon enters bike races. He bikes 7 1/2 miles every 1/2 hour. complete the table to find out how far Brandon bikes for each time interval
Answer:
12. Since there is no table given I will assume that what you want me to do is to show that Unit rate of Brandon’s biking. SO here are the data that we need: => 8 and ½ miles = 8.5 miles => ½ hour = .5 hours or 30 minutes Now, let’s solve for the unit rate => SO in every 30 minutes he bikes around 8.5 miles => Since 1 hour is equals to 30 minutes, simply multiply 8.5 by 2 => 8.5 * 2 = 17miles => 17 miles / hour
Step-by-step explanation:
divide 612 by 12

Answer:
a) y = (x -4)² -4
b) (4, -4)
c) translated 4 right, 4 down
Step-by-step explanation:
a) Apparently "graphing form" is a reference to "vertex form." That form is ...
y = a(x -h)² +k . . . . . . parabola with vertex (h, k) and vertical scale factor 'a'
The coefficient of x² in your given equation is 1, so a=1. The values of h and k can be found as follows.
'h' is the opposite of half the x-coefficient in your equation, so is h = -(-8/2) = 4. The value of k is the square of h, subtracted from the constant in your equation: k = 12 -h² = 12 -16 = -4. (This applies when a=1, as here.) These calculations are the "cut to the chase" version of "completing the square."
The method of "completing the square" has you consider the x-terms separately from the constant term:
y = (x² -8x) +12
To "complete the square", you want to make the terms in parentheses be a perfect square trinomial. You do that by adding the square of half the x-coefficient. In order to keep the same equation, you need to subtract an equivalent amount outside parentheses:
y = (x² -8x +(-8/2)²) +12 -(-8/2)² . . . . . add and subtract (-8/2)²
y = (x -4)² +(12 -16)
Then the vertex form is ...
y = (x -4)² -4 . . . . and the vertex is (h, k) = (4, -4).
The graphing calculator plot attached confirms this vertex value.
__
The problem statement tells you that you can also find this form by averaging the x-intercepts. If you factor your equation, you get ...
y = (x -6)(x -2)
The x-values that make these factors zero {6, 2} are the x-intercepts. Their average (6+2)/2 = 4 is the x-coordinate of the vertex (h). You can find the y-coordinate of the vertex by evaluating y when x=4: y = 4² -8·4 +12 = -4. So, the vertex by this method is (h, k) = (4, -4), and the equation in graphing form is ...
y = (x -4)² -4 . . . . as above.
__
b) As we saw above, the vertex coordinates are (h, k) = (4, -4).
__
c) The vertical scale factor 'a' is 1, so the only transformation done on the graph is to move the parent vertex (0, 0) to the location (4, -4). That is, the graph has been translated 4 units right and 4 units down. (In the attached, the parent function is shown with a dashed line.)
152=8(3a-2) justify each step
Step-by-step explanation:
152 = 8(3a - 2)
152 = 8 × 3a - 8 × 2
152 = 24a - 16
152 + 16 = 24a
168 = 24a
a = 168/24
a = 7
Answer:
-7
Step-by-step explanation:
152=8(3a-2)
8(3a-2)=152
8(3a-2)/8=(152){8)
3a-2=19
3a-2+2=19+2
3a=21
3a/3=21/3
a=-7

Write an equation of the line that passes through (2,-1) and is parallel to the line y=-3x+8
Answer:
y = - 3x + 5
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = - 3x + 8 ← is in slope- intercept form
with slope m = - 3
Parallel lines have equal slopes, then
y = - 3x + c ← is the partial equation
To find c substitute (2, - 1) into the partial equation
- 1 = - 6 + c ⇒ c = - 1 + 6 = 5
y = - 3x + 5 ← equation of line

The price of a wakeboard that regularly sells for $600 is reduced to $528 by what percentage is the price reduced?
Answer:
12%
Step-by-step explanation:
600-528=72. (subtract)
72/600= 3/25. (simplify)
3/25 = 12%. ( convert to percent)
(answer accuracy not garunteed)
Answer:
600-528 = 72
72/600 = 0.12
0.12 X 100 = 12 %
It is reduced by 12 %
