Answer:

(x - 5) (x + 1)

Step-by-step explanation:

x² - 4x - 5

= x² + x - 5x - 5

= x(x + 1) - 5(x + 1)

= (x - 5) (x + 1)

If 5x-26=x+50, then the value of x is
horsena [70]
Let's work this problem out!

First: 5(x) - 26 - x + 50 = ? 

Second: 4(x) - 76 = ? 

Third: 4 = ? 
          ↑
(Solve Step 3) 

Fourth: x - 19 = 0 
                   ↑
(Add the number 19 to each of your sides for Step 4)

Finally we get to your answer

19 + 0 = 19 ; 19 - 19 = 0

So, therefore the value of "x" is 19 

x = 19

For what value of the constant c is the function fcontinuous on (−[infinity], [infinity])?
Arlecino [84]

Answer:

For c=\frac{1}{7} the function f(x) is continuous on (-\infty,\infty).

Step-by-step explanation:

We have the following function

f(x) = \left\{        \begin{array}{ll}            cx^2+5x & \quad x

For the function f(x) to be continuous on (-\infty,\infty) it is sufficient to have continuity at x = 6, we need to ensure that as x approaches 6, the left and right limits match, this means that

\lim_{x \to 6^{-} } f(x)=\lim_{x \to 6^{+} } f(x)=f(x),

which holds if and only if

c\left(6\right)^2+5\left(6\right)=\left(6\right)^2-c\left(6\right)\\36c+30=36-6c\\42c=6

namely if c=\frac{1}{7}.

Triangle ABC has verrocktes A (2,-1) B ( -3,0) and C ( -1,4) . Find the vertices of the image of triangle and after a translatio
belka [17]

Answer:

A(2,1) , B(-3,2) , C(-1,6)

Step-by-step explanation:

A translation of 2 units up means the y values will be shifted up 2 units

A (2,-1) -> A(2,1)

B (-3,0) -> B(-3,2)

C (-1,4) -> C(-1,6)

NO LINKS Write an inequality to represent the phrase: The sum of a number and seven less than a number
german

Answer:

The sum of a number, which I have named 'n', and 7 can be written as the expression:

n+7

remember the word 'is' in a written problem indicates where you'll most likely use an =,≥,≤ sign. Since they say that it is 'no more than' we know that n+7 is less than or equal to the given number, so we use '≤'.

n+7≤ 1

I need help i will mark brainliest
Kipish [7]

Answer:

Both triangles are scalene & Both triangles have an obtuse angle.

Step-by-step explanation:

<u>Key skills needed: Triangle recognition, Comparing Triangles</u>

1) We are given those 2 triangles, and we need to see if they are isosceles, scalene, obtuse, and acute.

2) To get this, let's define each thing:

Acute triangle - Means that all the angles in triangle are acute, which means they are less than 90 degrees in measure.

Obtuse triangle - Means that one angle in the triangle is obtuse, which means it is greater than 90 degrees in measure.

Scalene triangle - All the sides of the triangle are different in size/length

Isosceles triangle - 2 sides of the triangle are the same length

3) Now, we can use this to see what both triangles are:

--> Both triangles are not isosceles, they are both scalene. This is because all the sides of each triangle are different in size/length. This makes it scalene.

--> Both triangles are not acute triangles, they are both obtuse triangles. This is since the largest angle in each triangle is clear an obtuse angle (it looks like it is more than 90 degrees). Refer to the image I post as help.

With the observations above: We can say that both triangles are scalene, and both triangles are obtuse triangles.
