Answer:
9
Step-by-step explanation:
UT^2 = UV * UW
6^2 = (x - 7)(x - 7 + 5)
36 = (x - 7)(x - 2)
36 = x^2 - 2x - 7x + 14
x^2 - 9x - 22 = 0
(x - 11)(x + 2) = 0
x - 11 = 0 or x + 2 = 0
x = 11
UW = x - 7 + 5
UW = 11 - 7 + 5
UW = 9
Answer:
y = 6x +2
Step-by-step explanation:
It is useful to start with the point-slope form of the equation for a line when you are given a point and a slope.
y -k = m(x -h) . . . . line with slope m through point (h, k)
y -(-22) = 6(x -(-4))
y +22 = 6x +24 . . . simplify
y = 6x +2 . . . . . . subtract 22
Answer
I think 10
Hope this help
Answer:
I sorry to tell you but there is really no way to figure out that problem... I would need an abreviation denom. in order to answer it and there isnt one . Just let your teacher know.
Step-by-step explanation:
Answer:
1 Sweater = <em>$</em><em>1</em><em>2</em>
1 Shirt = <em>$</em><em>1</em><em>0</em>
1st.
Sw = y
Sh = x
2nd: <em>set</em><em> </em><em>the</em><em> </em><em>problem</em><em> </em><em>into</em><em> </em><em>a</em><em> </em><em>function</em><em>. </em>
<em>-</em><em> </em><em>One</em><em> </em><em>sweater and four shirts cost $52</em><em>.</em>
y+x+x+x+x = $52
and
- Four sweaters and five shirts cost $98.
y+y+y+y+x+x+x+x+x = $98
3rd.
y+x+x+x+x = $52
y = 52-x-x-x-x
y = 52-4x
4th. <em>if</em><em> </em><em>y</em><em> </em><em>=</em><em> </em><em>5</em><em>2</em><em>-4x</em><em>,</em><em> </em><em>we</em><em> </em><em>will</em><em> </em><em>substitute</em><em> </em><em>on</em><em> </em><em>the</em><em> </em><em>second</em><em> </em><em>equation</em><em>. </em>
y+y+y+y+x+x+x+x+x = $98
52-4x+52-4x+52-4x+52-4x+5x = 98
208-16x+5x = 98
-16x+5x = 98-208
-11x = -110
x = -110/-11
x = 10
5th. if <em>x</em><em> </em><em>=</em><em> </em><em>1</em><em>0</em><em>,</em><em> </em>now that we know what x equals to, we will substitute on the first equation to find out what y equals to.
y = 52-4x
y = 52-(4)(10)
y = 12
----------,-----------,---------,-----------,--------,--------,---------
Sweater = $12
Shirt = $10
