Answer:

8.3 is to 1d.p so to find the error interval, you divide 0.1 by 2 = 0.05

8.3 + 0.05 = 8.35

8.3 - 0.05 = 8.25

8.25<y<8.35

Answer:

a.) x²+h²+2xh-8x-8h

b.) h+2x-8

Step-by-step explanation:

A.) you just plug in x+h wherever there's an x

which means you have

(x+h)²-8(x+h)

simplify and get

x²+h²+2xh-8x-8h

we already know what f(x+h) is so we just need to subtract f(x) we have

x²+h²+2xh-8x-8h-x²+8x

simplify and get

h²+2xh-8h

Divide this by h and get

h+2x-8

Answer:

h+2x-8

Answer:

11 [tex]\frac{3}{8}[/tex] miles.

Step-by-step explanation:

To find how many miles Brandon rode, we can create an equation in slope-intercept form: y = mx + b

$2.25 is the flat fee, or the unchanging variable. This is our y-intercept, or b.

$0.40 is the changing variable, as it changes value depending on the amount of miles ridden. This is our slope, or m.

We know Brandon spent $6.80 on the cab ride. So, this is our y.

We get the equation: 6.80 = 0.40x + 2.25.

To solve, first subtract 2.25 from both sides of the equation:

6.80 - 2.25 = 0.40x + 2.25 - 2.25

We get: 4.55 = 0.40x

Now, just divide by 0.40 on both sides:

4.55 ÷ 0.40 = 0.40x ÷ 0.40

We get: 11.375 = x

So, Brandon rode for 11.375 miles. When converted to a mixed number, we get 11 [tex]\frac{3}{8}[/tex] .

Answer:

[tex]y = -\frac{5}{2}x +6[/tex]

Step-by-step explanation:

Given

[tex]m = -\frac{5}{2}[/tex] -- slope

[tex](x_1,y_1) = (2,1)[/tex] --- point

Required

Determine the line equation

In slope intercept form, a line equation is:

[tex]y - y_1 = m(x - x_1)[/tex]

This gives:

[tex]y - 1 = -\frac{5}{2}(x - 2)[/tex]

Open bracket

[tex]y - 1 = -\frac{5}{2}x +5[/tex]

Add 1 to both sides

[tex]y - 1+1 = -\frac{5}{2}x +5+1[/tex]

[tex]y = -\frac{5}{2}x +6[/tex]

Answer:

2 hours

Step-by-step explanation:

To solve this question, we can convert the fraction into decimal form momentarily, so that 5 1/2 is now 5.5, and 3 1/2 is now 3.5. We know that Sara has already driven 3.5 hours, and it takes 5.5 to get to her aunts house. To dins how much longer Sara has left to drive, simply subtract the total amount of hours by the hours already completed:

5.5 - 3.5 = 2.0

Meaning, Sara has 2 hours left to drive

Answer:

∠DGB = 101°

Step-by-step explanation:

Given:

∠CGB = 79°

Find:

∠DGB

Computation:

We know that CD is a straight line

So,

∠CGB + ∠DGB = 180

79 + ∠DGB = 180

∠DGB = 101°

Answer:

x = 20

Step-by-step explanation:

4(x + 7) - 5x + 2 = 10

open the parenthesis

4 * x + 4 * 7 - 5x + 2 = 10

4x + 28 - 5x + 2 = 10

combine like terms

-x + 30 = 10

subtract 30 from both sides of the equation

-x + 30 - 30 = 10 - 30

-x = 10 - 30

-x = -20

mutiply the equation by -1

-1 * -x = -20 * -1

x = 20

Answer:

Area = 396 units²

Step-by-step explanation:

Let's assume:

Length = 2c - 5

Width = 5c + 9

Perimeter = 2(L + W) = 106 units

Thus:

2[(2c - 5) + (5c + 9)] = 106

Find the value of c

2[2c - 5 + 5c + 9] = 106

2[7c + 4] = 106

14c + 8 = 106

14c = 106 - 8

14c = 98

Divide both sides by 14

c = 98/14

c = 7

✔️Area of the rectangle = Length × Width

Area = (2c - 5)(5c + 9)

Plug in the value of c

Area = (2×7 - 5)(5×7 + 9)

Area = (14 - 5)(35 + 9)

Area = (9)(44)

Area = 396 units²

The value of P for the given angles of the quadrilaterals is 6.

One of the earliest areas of mathematics is geometry, along with arithmetic. It is concerned with spatial characteristics like the separation, shape, size, and relative placement of objects.

Given that the two opposite angles are 4P + 12 and 36 respectively.

The value of P for the two opposite angles will be calculated as:-

4P + 12 = 36

4P = 36 - 12

4P = 24

P = 24 / 4

P = 6

Hence, the value of P for the given angles of the quadrilaterals is 6.

In table 4, for increasing x value, the y values are decreasing. Therefore, option 4 is the correct answer.

Scatter plots are used to observe and plot relationships between two numeric variables graphically with the help of dots. The dots in a scatter plot shows the values of individual data points.

A scatter plot with an increasing value of one variable and a decreasing value for another variable can be said to have a negative correlation.

In the given table 4, we can see for increasing x value, the y values are decreasing.

Therefore, option 4 is the correct answer.
