What is the difference? PLEASE HELP

Answer:

x = 19

Step-by-step explanation:

Assuming the question was (5x + 4)° (8x – 71)°=180° not (5x + 4)° (8x – 710°,

Simplifying

(5x + 4) + (8x + -71) = 180

Reorder the terms:

(4 + 5x) + (8x + -71) = 180

Remove parenthesis around (4 + 5x)

4 + 5x + (8x + -71) = 180

Reorder the terms:

4 + 5x + (-71 + 8x) = 180

Remove parenthesis around (-71 + 8x)

4 + 5x + -71 + 8x = 180

Reorder the terms:

4 + -71 + 5x + 8x = 180

Combine like terms: 4 + -71 = -67

-67 + 5x + 8x = 180

Combine like terms: 5x + 8x = 13x

-67 + 13x = 180

Solving

-67 + 13x = 180

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '67' to each side of the equation.

-67 + 67 + 13x = 180 + 67

Combine like terms: -67 + 67 = 0

0 + 13x = 180 + 67

13x = 180 + 67

Combine like terms: 180 + 67 = 247

13x = 247

Divide each side by '13'.

x = 19

Simplifying

x = 19

Step-by-step explanation:

Given the following :

Equation of regression line :

Yˆ = −114.05+2.17X

X = Temperature in degrees Fahrenheit (°F)

Y = Number of bags of ice sold

On one of the observed days, the temperature was 82 °F and 66 bags of ice were sold.

X = 82°F ; Y = 66 bags of ice sold

1. Determine the number of bags of ice predicted to be sold by the LSR line, Yˆ, when the temperature is 82 °F.

X = 82°F

Yˆ = −114.05+2.17(82)

Y = - 114.05 + 177.94

Y = 63.89

Y = 64 bags

2. Compute the residual at this temperature.

Residual = Actual value - predicted value

Residual = 66 - 64 = 2 bags of ice

Answer: 5r+63

Step-by-step explanation: Combine Like Terms:

=10+71+−18+5r

=(5r)+(10+71+−18)

=5r+63

Problem 1

--------------------------------

Explanation:

The x intercepts are -1 and 3, meaning that (x+1) and (x-3) are factors.

This is because x = -1 leads to x+1 = 0 when you add 1 to both sides. And x = 3 leads to x-3 = 0 when you subtract 3 from both sides.

The quadratic equation would be y = a(x+1)(x-3) = a(x^2-2x-3) for some constant 'a'. Use the point (x,y) = (1,-8) to find the value of 'a'.

y = a(x^2-2x-3)

-8 = a(1^2-2*1-3)

-8 = a(-4)

-4a = -8

a = -8/(-4)

a = 2

Therefore,

y = a(x^2-2x-3)

y = 2(x^2-2x-3)

y = 2x^2-4x-6

======================================================

Problem 2

--------------------------------

Explanation:

We'll follow the same idea as the previous problem.

The factors are (x-0) and (x-1). This is the same as saying the factors are x and (x-1)

So we have y = ax(x-1) = a(x^2-x)

Plug in (x,y) = (2,-2) and solve for 'a'.

y = a(x^2-x)

-2 = a(2^2-2)

-2 = a(2)

2a = -2

a = -2/2

a = -1

The equation updates to

y = a(x^2-x)

y = -1(x^2-x)

y = -x^2+x

Answer:  1) y = 2(x + 1)(x - 3)

               2) y = -(x)(x - 1)

Step-by-step explanation:

Use the Intercept form of a quadratic equation: y = a(x - p)(x - q) where

1) p = -1, q = 3, (x, y) = (1, -8)

y = a(x + 1)(x - 3)

-8 = a(1 + 1)(1 - 3)

-8 = a(2)(-2)

-8 = -4a

2 = a

Equation: y = 2(x + 1)(x - 3)

2) p = 0, q = 1, (x, y) = (2, -2)

y = a(x - 0)(x - 1)

-2 = a(2 - 0)(2 - 1)

-2 = a(2)(1)

-2 = 2a

-1 = a

Equation: y = -(x)(x - 1)

Answer:

In general, an unresolved nth root, commonly involving a radical symbol ^n√x, is known as a surd. However, the term surd or "surd expression" (e.g., Hardy 1967, p. 25) can also be used to mean a sum of one or more irrational roots. In the mathematical literature, the term arises most commonly in the context of quadratic surds.

Answer:

Hope this help

Step-by-step explanation:

Plug in the y value found from the first equation in to the second equation in order to find the x value. In the previous example, this means the second equation becomes "x + 5(2- 3x) = 20"

Solve for x. The example equation becomes "x + 10 - 15x = 20," which is then "-14 x + 10 = 20." Subtract 10 from each side, divide by 14 and you have end up with x = -10/14, which simplifies to x = -5/7.

Plug in the x value in to the first equation to find out the y value. y = 2 - 3(-5/7) becomes 2 + 15/7, which is 29/7.

Answer:

Step-by-step explanation:

We know that the sum of the angles of a triangle is 180

HCA + CAH + AHB = 180

80+ CAH + 90 = 180

Combine like terms

170 + HAC = 180

HAC= 180-170

HAC = 10

We also know that HCA + ACB is a straight line so it adds to 180

HCA + ACB = 180

80+ACB = 180

ACB = 180-80

ACB = 100

Since ACB is isosceles the base angles have the same measure so CAB = ABC

We know that the sum of the angles of a triangle is 180

CAB + ABC + ACB = 180

Replacing ABC with CAB

CAB + CAB + 100 = 180

2CAB + 100 =180

2 CAB = 180-100

2 CAB = 80

Divide by 2

CAB = 80/2

CAB = 40

Now find HAB

HAB = HAC + CAB

        = 10 + 40

         = 50

Answer:

[tex]\huge\boxed{6.2 + (\frac{6.2}{2}) + x = 14.5}[/tex]

Step-by-step explanation:

To create an equation for this, we have to note a couple of things.

We know that the longest side is 6.2 cm long. We also know that the longest side is twice the length of the shortest side. Therefore, the shortest side will be half the amount of the longest side.

Basically - we divide the longest side by 2 (6.2) so [tex]\frac{6.2}{2}[/tex].

We don't know the third side. However, we know the total perimeter (14.5). Therefore, we can use a placeholder for the third side - [tex]x[/tex].

Adding up all the sides, we have [tex]6.2 + (\frac{6.2}{2}) + x = 14.5[/tex].
