Answer:

 x = -2  and x =12

Step-by-step explanation:

<u><em>Explanation</em></u>:-

Given equation  x² - 10 x - 24=0

                          x² - 12 x +2x - 24 =0

                ⇒   x (x-12) +2( x -12) =0

              ⇒  x+2 =0 and x-12 =0

             x = -2  and x =12

<em>Hi there !</em>

<em>6×7 - 3²×9 + 4³ =</em>

<em>   1. raise the numbers to power</em>

<em>= 6×7 - 9×9 + 64</em>

<em>   2. we perform the multiplications</em>

<em>= 42 - 81 + 64</em>

<em>   3.  we perform addition and subtraction</em>

We have that

<span>y=2sinx-cosx
y=cosx
</span>over the interval 0≤x≤pi/2-------> 0≤x≤1.57

using a graph tool
see the attached figure

the solution in the given interval is the point (pi/4, 0.707)
the y-value of the point of intersection is 0.707 -----> √2/2

the answer is the option

lyudmila [28]

The amount of decrease is $12.00 :$72.00 - $60.00 = $12.00

 you then divide the amount of decrease by the original price to find the  percent decrease:

   $12.00 ÷ $72.00  =  .166666...  =  16.7%

X(1+y)=z solve for x
dem82 [27]
<span>X(1+y)=z
Multiply x by 1 and y
x + xy=z
Divide y on both sides
x + x = z/y
Add x to x
2x = z/y
Divide 2 on both sides
Final Answer: x= z/y/2  
Word Form: x equals z divided by y all over two.

Jacob needs to collect at least 120 cans for a food drive to earn community service credit. He has already collected 64 items.
dalvyx [7]

An inequality that represent  the number of cans, c, that Jacob must still collect is  c\geq 56 .

<u>Step-by-step explanation:</u>

Here we have , Jacob needs to collect at least 120 cans for a food drive to earn community service credit. He has already collected 64 items.  We need to solve the following :

<u>Part A: </u>

Write and solve an inequality to represent the number of cans, c, that Jacob must still collect.

Jacob has collected 64 cans . Jacob need to collect at least 120 cans for a food drive to earn community service credit , Let Number of cans that Jacob have to collect is c , So following is the inequality for above scenario:

⇒ c+64\geq 120

⇒ (c+64)-64\geq 120-64

⇒ c\geq 56

Therefore , An inequality that represent  the number of cans, c, that Jacob must still collect is  c\geq 56 .
