Here,

Perimeter (P)=86 feet

Length (l)=25 feet

Let, width(b)= x feet

Then,

Perimeter= 2(l+b)

86=2(25+x)

43=25+x

x=18

Hence, required width is 18 feet...

I need help with this:What is the value of y? Enter your answer in the box. y =
lina2011 [118]

Answer:

y=5 degrees

Step-by-step explanation:

It is an isosceles triangle so that means that there are two angles that equal 75, so that means the third side with 4y + 10 is equal to 30 degrees.

4y+10=30

4y=20

y=5 degrees

Solve to find the value of x.<br> x+27=93<br><br> i need help
igomit [66]

Answer: 66

Step-by-step explanation:

To solve for x in x+27=93, subtract both sides of the equation by 27

X + 27 -27= 93 - 27

X= 66

I hope this helps

Solve the equation for y.<br> 2x + 5y = 5<br> y=x +1<br> y= -10% + 25<br> y=22+1<br> y=x +5
Elena-2011 [213]

Answer:

y=-2/5x+1

y=x+1

y=249/10

y=23

y=x+5

Step-by-step explanation:

Let's solve for x.

y=x+5

Step 1: Flip the equation.

x+5=y

Step 2: Add -5 to both sides.

x+5+−5=y+−5

x=y−5

Answer:

x=y−5

Describe the graph that would be used to solve the equation –x2 + 4 = x + 2 using a system of equations. How will you use the gr
gayaneshka [121]

Answer:

The solutions are (-2 , 0) and (1 , 3)

Step-by-step explanation:

∵ -x² + 4 = x + 2

* y = -x² + 4 ⇒ is quadratic represented by parabola

 The parabola open downward because coefficient of x² is negative

 The x-coordinate of its vertex = -b/2a, where b is the

  coefficient of x and a is the coefficient of x²

∴ x = 0/2(-1) = 0

∴ The y-coordinate of the vertex = (0)² + 4 = 4

∴ The maximum point of the parabola is (0 , 4)

∵ -x² + 4 intersects x-axis at y = 0

∴ -x² + 4 = 0 ⇒ -x² = -4 ⇒ x² = 4

∵ x² = 4

∴ x = ±√4 = ± 2

∴ the parabola intersects x-axis at -2 , 2

∵ y = x + 2 represented by a line its slope = 1

  It intersects y-axis at 2

∵ x + 2 intersects x-axis at y = 0

∴ x + 2 = 0

∴ x = -2

∴ The parabola and the line intersect each other at

  x = -2 and y = 0

To find all the point of intersection between the 2 equations we will solve them as a system of equations

∵ y= -x² + 4  and y = x + 2

∴ -x² + 4 = x + 2

∴ -x² + 4 - x - 2 = 0

∴ -x² - x + 2 = 0 ⇒ × -1

∴ x² + x - 2 = 0 ⇒ factorize

∴ (x + 2)(x - 1) = 0

∴ x + 2 = 0 ⇒ x = -2

∴ x - 1 = 0 ⇒ x = 1

* when x = -2 ⇒ y = -2 + 2 = 0 ⇒ (-2 , 0)

* when x = 1 ⇒ y = 1 + 2 = 3 ⇒ (1 , 3)

The solution graphically
