Answer:
13
Step-by-step explanation:
4 + 9
[ 9 + 2 = 11 ]
[ 11 + 2 = 13 ]
Answer:
2
Step-by-step explanation:
<em>for </em><em>this </em><em>question</em><em> </em><em>you've </em><em>to </em><em>cross </em><em>multiply</em>
<em>-</em><em>2</em><em>2</em><em>/</em><em>9</em><em>r</em><em>=</em><em>1</em><em>1</em><em>/</em><em>9</em>
<em>9</em><em>9</em><em>r</em><em>=</em><em>-</em><em>1</em><em>9</em><em>8</em>
<em>then </em><em>you </em><em>divide</em><em> both</em><em> sides</em><em> by</em><em> </em><em>9</em><em>9</em><em> </em><em>inorder </em><em>to </em><em>remain </em><em>with </em><em>r </em><em>on </em><em>one </em><em>side</em>
<em>9</em><em>9</em><em>r</em><em>/</em><em>9</em><em>9</em><em>=</em><em>1</em><em>9</em><em>8</em><em>/</em><em>9</em><em>9</em>
<em>r=</em><em>2</em>
<em>I </em><em>hope </em><em>this </em><em>helps</em>
Answer:
14.29
Step-by-step explanation:
Let p be the price of the cd
we take the price of the cd plus the tax and it must be less than or equal to 15
the tax is the price of the cd times 5 %
p + p*.05 ≤15
Combine like terms
p*1.05 ≤15
Divide each side by 1.05
p ≤15/1.05
p ≤14.28571429
Rounding to the nearest cent
p ≤14.29
The maximum price is 14.29
Answer:
Explanation:
The given points are:
- (0, 275)
- (1, 220)
- (2, 165)
- (3, 110)
- (4,55)
- (5, 0)
Since a <em>straight line joins</em> all the points, the equation that models the <em>relationship</em> is linear and you can find the slope-intercept equation which has the general form:
Where:
is the slope
is the y-intercept
<u>1. Find the slope</u>
You can use any two ordered pairs.
- m = rise/run = Δy/Δx = [220 - 275] /[1 - 0] = - 55
<u>2. Find the y-intercept</u>
The y-intercept is the value of y when x = 0; thus it is 275.
<u>3. Substitute in the slope-intercept equation</u>
That is the last option.
