Use the quadratic formula to find the solutions to the
quadratic equation below.
2x2 - 5x + 5 = 0

Let's solve your equation step-by-step.

2(x+4)=−5x+1

Step 1: Simplify both sides of the equation.

2(x+4)=−5x+1

(2)(x)+(2)(4)=−5x+1(Distribute)

2x+8=−5x+1

Step 2: Add 5x to both sides.

2x+8+5x=−5x+1+5x

7x+8=1

Step 3: Subtract 8 from both sides.

7x+8−8=1−8

7x=−7

Step 4: Divide both sides by 7.

Hey there!☺

[tex]Answer:\boxed{11x+10y=-10}[/tex]

[tex]Explanation:[/tex]

[tex]y=\frac{-11}{10}x -1[/tex] in standard form

Rewrite in standard form.

[tex]{11x+10y=-10[/tex]

Hope this helps!

The standard form of the equation is 11x + 10y = -10.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

The given equation is  y=-11/10x-1. The standard form of the equation can be written as,

y=-11/10x-1

10y = -11x - 10

11x + 10y = -10

Hence, the standard form of the equation is 11x + 10y = -10.

Answer:

t ≤ 15

Step-by-step explanation:

One third of 15 is equal to five (1/3 × 15 = 5)

One third of t is lesser than or equal to five (1/3 × 5 ≤ 5)

So, t cannot be more than 15. It can be equal to 15, though.

∴t ≤ 15

Answer:

area =729 feet square

perimeter =  108 feet

Step-by-step explanation:

Given the side of a square is 9 cm.

The scale is given as :

1 cm = 3 feet

Since 1 cm represents 3 feet.

Therefore, 9 cm will represent = 9 x 3 feet

                                                  = 27 feet

So the side of the square is 27 feet.

Therefore, its area = Side x side

                               = 27 x 27

                               = 729 feet square

And the perimeter =  4 x side

                               = 4 x 27

                                = 108 feet

Answer:

Step-by-step explanation:

The equation 6x + 3 = 27 is equivalent to 2x = 8 because you can divide 8 by 2x to get X=4. To solve 6x + 3 = 27, you can subtract 3 to both sides of the equal sign to end up with 6x = 24, and from there you can divide 24 by 6x and also end up with X = 4. Both equations have the same answer.

The 10th term of the given sequence is -10190.

Functions are the fundamental part of the calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.

The given function is f(1)=30; f(n)=2×f(n-1)-50.

Here,

When n=2

f(2)=2×f(2-1)-50

=2×f(1)-50

= 2×30-50

= 10

When n=3

f(3)=2×f(3-1)-50

=2×f(2)-50

= 2×10-50

= -30

When n=4

f(4)=2×f(4-1)-50

=2×f(3)-50

= 2×(-30)-50

= -60-50

= -110

When n=5

f(4)=2×f(5-1)-50

=2×f(4)-50

= 2×(-110)-50

= -220-50

= -270

When n=6

f(4)=2×f(6-1)-50

=2×f(5)-50

= 2×(-270)-50

= -540-50

= -590

When n=7

f(4)=2×f(7-1)-50

=2×f(6)-50

= 2×(-590)-50

= -1180-50

= -1230

When n=8

f(4)=2×f(8-1)-50

=2×f(7)-50

= 2×(-1230)-50

= -2510

When n=9

f(4)=2×f(9-1)-50

=2×f(8)-50

= 2×(-2510)-50

= -5070

When n=10

f(4)=2×f(10-1)-50

=2×f(9)-50

= 2×(-5070)-50

= -10190

Therefore, the 10th term of the given sequence is -10190.

[tex]x=-2[/tex]

Step-by-step explanation:

So we have the equation:

[tex]6-4x=7x-9x+10[/tex]

First, combine like terms on the right:

[tex]6-4x=-2x+10[/tex]

Add 4x to both sides. The left cancels:

[tex]6=2x+10[/tex]

Subtract 10 from both sides. The right cancels:

[tex]-4=2x[/tex]

Divide both sides by 2:

[tex]x=-2[/tex]

So, the value of x is -2.

And we're done!

Step-by-step explanation:

[tex]6 - 4x = 7x - 9x + 10 \\ 6 - 4x = - 2x + 10 \\ 6 - 10 = - 2x + 4x \\ - 4 = 2x \\ x = \frac{ - 4}{2} \\ x = - 2[/tex]

Answer:

3x + 8 is equal to 14 when x = 2.

Step-by-step explanation:

To evaluate the expression 3x + 8 when x = 2, we simply subsititute the value of x into the expression.  We can write this expression as the function:

f(x) = 3x + 8

And we can evaluate the function when x = 2 by simply plugging in the value 2 for x:

f(x) = 3x + 8

f(2) = 3(2) + 8

f(2) = 6 + 8

f(2) = 14

Hence, the expression 3x + 8 is equal to 14 when x = 2.
