How many solutions does the following equation have? -6(x + 7) = -4.x - 2

Mathematics

Answer:

x=-20

Step-by-step explanation:

Given

-6(x+7)= -4x - 2

First of all, we have to solve brackets

So,

-6x-42=-4x-2

To find the solution of this equation, we have to isolate x on one side of the equation.

Adding 4x on both sides

-6x-42+4x = -2-4x+4x

-2x-42 = -2

Adding 42 on both sides

-2x-42+42 = -2+42

-2x=40

Dividing both sides by -2

-2x/2 = 40/-2

x = -20

The equation has only one solution which is x=-20 ..

Carmen runs 7 miles in 60 minutes. At the same rate, how many miles would she run in 24 minutes?
zhuklara [117]
Hey there,
60 minutes = 7 miles
1 minute = 7 / 60  
               = 7/60
24 minutes = 7/60 x 24
                   =2.8 miles

Hope this helps :))

(-4)(-4) use an exponent to rewrite the expression
DiKsa [7]
For this case we have the following expression:
<span> (-4)(-4) &#10;
 By properties of exponents we have:
 Same basis, the exponents are added.
 We have then:
 (-4)^{1+1}
 Then, rewriting the exponent we have:
 (-4)^{2}
 Therefore, an exponent to rewrite the expression is:
 2
 Answer:
 
(-4)^{2}
 an exponent to rewrite the expression is 2.</span>

Answer:

C) f(x) = 6.25x + 3

Step-by-step explanation:

In order to know which one of the functions could produce the results in the table we simply need to substitute the number of candy bars for x in the function and solve it to see if it provides the correct total weight shown in the table. If we do this with the functions provided we can see that the only one that provides accurate results would be

f(x) = 6.25x + 3

We can input the # of candies for x and see that it provides the exact results every time as seen in the table.

f(x) = 6.25(1) + 3 = 9.25

f(x) = 6.25(2) + 3 = 15.50

f(x) = 6.25(3) + 3 = 21.75

f(x) = 6.25(4) + 3 = 28
