Factor f(x) = x2 + 3x − 4.
Answer:
(x - 1)(x + 4)Step-by-step explanation:
Find zero's of function:
x² + 3x - 4 = 0x = (-3 ± √(3² + 4*4))/2x = (-3 ± √25)/2x₁ = (-3 + 5)/2 = 1x₂ = (-3 - 5)/2 = -4The factors are:
x² + 3x - 4 = (x - 1)(x + 4)The hypotenuse of a right triangle is 10 meters and its
legs measure x and x + 2. How long are the legs?
Let's solve by using Pythagoras theorem,
[tex] \hookrightarrow \: (10) {}^{2} = {(x})^{2} + (x + 2) {}^{2} [/tex]
[tex] \hookrightarrow \: 100 = {x}^{2} + {x}^{2} + 4x + 4[/tex]
[tex] \hookrightarrow \: 100 - 4 = 2 {x}^{2} + 4x[/tex]
[tex] \hookrightarrow \: 96 = 2 {x}^{2} + 4x[/tex]
[tex] \hookrightarrow \: 2 {x}^{2} + 4x - 96 = 0[/tex]
[tex] \hookrightarrow \: 2( {x}^{2} + 2x - 48) = 0[/tex]
[tex] \hookrightarrow \: {x}^{2} + 2x - 48 = 0[/tex]
[tex] \hookrightarrow \: {x}^{2} + 8x - 6x - 48 = 0[/tex]
[tex] \hookrightarrow \: x(x + 8) - 6(x + 8) = 0[/tex]
[tex] \hookrightarrow \: (x + 8)(x - 6) = 0[/tex]
now there are two cases
Case 1 : when (x + 8) = 0
[tex] \hookrightarrow \: x + 8 = 0[/tex]
[tex] \hookrightarrow \: x = - 8[/tex]
but the value of x can't be negative, since side of a triangle isn't a negative value .
Case 2 : when (x - 6) = 0
[tex] \hookrightarrow \: x - 6 = 0[/tex]
[tex] \hookrightarrow \: x = 6[/tex]
therefore the measure of other two sides are :
[tex] \hookrightarrow \: x = 6 \: units[/tex]
[tex] \hookrightarrow \: x + 2 = 6 + 2 = 8 \: units[/tex]
[tex] \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \mathrm{TeeNForeveR } [/tex]

For the function f(x)=11x−169‾‾‾‾‾‾‾‾‾‾√3, find f(4).
Answer:
you replace the x with 4 that is
4= 11*4-169
Step-by-step explanation:
A farmer builds a fence for his chickens in the shape
of a pentagon, as shown. Each of the 5 sides has equal
length, but the fence along the highway costs twice as
much as any one of the other 4 sides. If the total cost
of fencing was $1800, how much did the highway
fence cost?
3 Find y if the slope between ( – 7, y) and (1, 13) is 3/4
Step-by-step explanation:
[tex]slope \: = \frac{y2 - y1}{x2 - x1} = \frac{3}{4} [/tex]
point 1 ( -7,y)
point 2 (1,13)
[tex] \frac{13 - y1}{1 - ( - 7)} = \frac{3}{4} [/tex]
[tex] \frac{13 - y1}{8} = \frac{3}{4} [/tex]
[tex]13 - y2 = \frac{8 \times 3}{4} = 6[/tex]
[tex]y2 = 13 - 6 = 7[/tex]
y = 7
what is the average of 34 and 91?
Answer:
62.5
Step-by-step explanation:
To find average, add up all numbers and divide by how many numbers there are.
34 + 91 = 125
125 / 2 = 62.5
Answer:
62.5
Step-by-step explanation:
Average = (34 + 91)/2 = 125/2 = 62.5
The sum of twice a number and five is fifteen. Find the number.
hi <3
we need to form an equation
lets call our unknown number 'x'
so now we have:
2x + 5 = 15
subtract 5 from both sides
2x = 10
divide both sides by 2 to get your answer of:
x = 5

Solve for x 4(x + 2) = 3 (x - 2)
Answer:
x = -14
)Step-by-step explanation:
To find the value of x
Transpose
4(x + 2) = 3 (x - 2)
4x + 8 = 3x - 6
4x - 3x = -6 -8
x = -14
we can even cross check
putting the value of x by -14
4(x + 2) = 3 (x - 2)
4 (-14 +2) = 3 (-14 -2)
-56 +8 = -42 -6
-48 = -48
same = same
so CROSS-CHECKED
Answer:
x = -14
Step-by-step explanation:
4(x + 2) = 3 (x - 2)
4x + 8 = 3x - 6
x + 8 = -6
x = -14

Maggie's brother is 4 years younger than twice her age. The sum of their ages is 29.
How old is Maggie?
Maggie is____
years old.
Answer:
11
Step-by-step explanation:
You have to make a system of equations. So the first equation would be b=2m-4 (b is brother m is maggie). The next equation is 29=m+b (sum of their ages). Then you can use substitution so plug in 2m-4 for b in the second question. So it would be 29=m+2m-4. Simplify and solve for m and you get 11.
