Answer:

a=7

Step by step Explanation:

Step 1: Simplify both sides of the equation.

1.3(a+2)+5.6=17.3

(1.3)(a)+(1.3)(2)+5.6=17.3(Distribute)

1.3a+2.6+5.6=17.3

(1.3a)+(2.6+5.6)=17.3(Combine Like Terms)

1.3a+8.2=17.3

1.3a+8.2=17.3

Step 2: Subtract 8.2 from both sides.

1.3a+8.2−8.2=17.3−8.2

1.3a=9.1

Step 3: Divide both sides by 1.3.

1.3a      9.1

1.3     =   1.3

a = 7

[tex]\boxed{\textsf{ The value of x is }\bf{ \dfrac{-5\pm\sqrt{21}}{2}}.}[/tex]

Step-by-step explanation:

A quadratic equation is given to us and we need to find the Solutions of the quadratic equation . So the given equⁿ is ,

[tex]\sf\implies (x+4)^2 -3(x+4) -3 = 0 [/tex]

Firstly let's simpify the quadratic equation and then use the quadratic formula also known as " Shreedhacharya's Formula" .

Taking the given equation :-

[tex]\sf\implies (x+4)^2 -3(x+4) -3 = 0\\\\\sf\implies x^2 + 16 + 8x -3x -12 -3 = 0 \\\\\sf\implies x^2+5x +1 = 0 [/tex]

Now let's use the Quadratic formula ,

Quadratic Formula :-

[tex]\qquad\boxed{\boxed{ \sf x =\dfrac{ -b \pm \sqrt{ b^2-4ac}}{2a} }} [/tex]

With respect to Standard form ax² + bx + c form. Here a = 1 , b = 5 and c = 1 .

[tex]\sf\implies x = \dfrac{ -5\pm \sqrt{ (5)^2-4(1)(1)}}{2(1)} \\\\\sf\implies x = \dfrac{ -5 \pm \sqrt{ 25 -4 } }{2} \\\\\sf\implies \boxed{\pink{\sf x = \dfrac{-5+\sqrt{21}}{2}, \dfrac{-5-\sqrt{21}}{2} }}[/tex]

A number squared is just the number times itself.

[tex]n(n)=n^2[/tex]

Answer:

A number squared is a number to the power of 2 or the number times itself.

Step-by-step explanation:

Lets say you have a 4 to the 2nd that would mean that the 4 is multiplied by 4. Dont get the exponent confused as the number to multiply it as. Look at [tex]9^{2}[/tex] for example, you would multiply the number 9 2 times not 9 times 2 so it would be 9x9.

The solutions of the given equation are x=4 and x=-4. Therefore, options B and E are the correct answers.

The solutions to the quadratic equation are the values of the unknown variable x, which satisfy the equation. These solutions are called roots or zeros of quadratic equations. The roots of any polynomial are the solutions for the given equation.

The given quadratic equation is x²-16=0.

Here, x²=16

x=±√16

x=±4

So, the solutions are x=4 and x=-4.

Therefore, options B and E are the correct answers.

Answer:

A)

[tex]\sqrt{290}\approx 17.0\text{ units}[/tex]

B)

[tex]\sqrt{53}\approx7.3\text{ units}[/tex]

Step-by-step explanation:

To find the distance between any two points, we can use the distance formula:

[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2[/tex]

Problem 1)

We have the two points (-4, 5) and (7, 18).

Let (-4, 5) be (x₁, y₁) and let (7, 18) be (x₂, y₂).

Substitute:

[tex]d=\sqrt{(7-(-4))^2+(18-5)^2}[/tex]

Evaluate:

[tex]\begin{aligned}d&=\sqrt{(11)^2+(13)^2}\\&=\sqrt{121+169}\\&=\sqrt{290}\approx17.0\end{aligned}[/tex]

Problem 2)

We have the two points (-2, -3) and (-4, 4).

Similarly, we will let (-2, -3) be (x₁, y₁) and (-4, 4) be (x₂, y₂).

Substitute:

[tex]d=\sqrt{(-4-(-2))^2+(4-(-3))^2[/tex]

Evaluate:

[tex]\begin{aligned}d&=\sqrt{(-2)^2+(7)^2}\\&=\sqrt{4+49}\\&=\sqrt{53}\approx7.3\end{aligned}[/tex]

Answer:

y = 6/5x -5

Step-by-step explanation:

Points are (5,1) (0,-5)

-5 - 1/ 0-5 = 6/5 slope

y-y1= m(x-x1)

y- 1 = 6/5(x-5)

y -1 = 6/5X - 6

y = 6/5X -5

Answer:

y = 3x + 11

Step-by-step explanation:

obviously since y is 11 when x is zero the constant term is 11.

Then use the other coordinates to find the cooefficent of x.

-4= c × -5 + 11

-4= -5c + 11

5c=15, c=3

Therefore the equation should be:

y= 3x + 11
