. Identify the slope and y-intercept of the
equation 2x + 5y = 20

Answer:

4

Step-by-step explanation:

we have been given the mean as 5 so it means you have to multiply five with the mean since there are five numbers .If you multiply you will get 25 then add 5+8+2+6 the answer you will get is 21 thn write an equation 21+x=25 because 21 has a positive sign infront of it when it crosses the equal sign it will change to a negative sign the equation will be x=25-21 if you subtract you will get 4 so x=4

Answer:

yes

Step-by-step explanation:

Answer:

B

Step-by-step explanation:

To determine which point lies on the line, substitute the x- coordinate of the point into the equation and if the value equals the y- coordinate of the point then it lies on the line.

A (4, 8)

y = - 3(4) + 4 = - 12 + 4 = - 8 ≠ 8 ← not on line

B (4, - 8 )

y = - 3(4) + 4 = - 12 + 4 = - 8 ← lies on line

C (- 4, 8 )

y = - 3(- 4) + 4 = 12 + 4 = 16 ≠ 8 ← not on line

D (- 4, - 8 )

y = - 3(- 4) + 4 = 12 + 4 = 16 ≠ - 8 ← not on line

The point lying on the line is (4, - 8 ) → B

Answer:

The scale drawing is correct for the length;

[tex]\overline{BC} = 5\dfrac{34}{35} \ in.[/tex]

Step-by-step explanation:

The diagram shows the rectangular cross-section of a roof truss

The given dimension of the side [tex]\overline{AB}[/tex] of the roof truss scale drawing = 9.5 in.

The actual length of the side [tex]\overline{AB}[/tex] on the roof truss = 38 feet

The actual length of the side [tex]\overline{BC}[/tex] on the roof truss = 22 feet

Therefore, the scale of the scale drawing is given as follows;

The scale of the drawing = (Scale dimension)/(Actual dimension)

38 feet = 9.5 inches on the drawing

∴ 1 foot = 9.5 inches/35 = 19/70 inches on the drawing

1 foot = 19/70 inches on the drawing

22 feet = (19/70 inches × 22) on the drawing = [tex]5\frac{34}{35}[/tex] inches on the drawing

The length of [tex]\overline{BC}[/tex] on the scale drawing =  [tex]5\frac{34}{35}[/tex] inches.

Answer:

This is in the simplest form already.

Step-by-step explanation:

The simplified form of the given expression 4x5p would be equal to 20xp.

Polynomials are those algebraic expressions that consist of variables, coefficients, and constants. The standard form of polynomials has mathematical operations such as addition, subtraction, and multiplication.

The given expression is 4x5p. we need to simplify the expression.

but the given expression has unlike terms 4x and 5p so, the, unlike a variable, could not be multiplied.

Now, the simplified form will be

4x5p

= 20xp

Answer:

$1105

Step-by-step explanation:

The area of the shape is 26 square feet.

This is a composite shape. It is made up of a trapezoid at the top and two identical parallelograms on the sides.

Here are the formulas for the area of each.

Trapezoid:

0.5(2)(6 + 8) = 14

Parallelogram:

2(3) = 6

Now, just add up the 3 parts:

14 + 6 + 6 = 26 sq ft

26 * 42.50 = $1105

Answer: here is an example in the screenshot

it is A,B,C, or D

Step-by-step explanation:

For a given perimeter, the area will be maximized when all the sides are the same length, which makes it actually a square. A square is still a rectangle, though! So, if you know the perimeter, divide it by four to determine the length of each side. Then multiply the length times the width to get the area.

BTW U CAN USE A CALCULATOR

Answer:

A

Step-by-step explanation:

The chance the coin will show 'tails' is 1/2, since there are only 2 sides to a coin. The chance that the die will show an even number is also 1/2, since half of the numbers on a die are even, and half are odd. But, since both of these events depend on each other, or in other words, are dependent, we have to multiply both numbers. 1/2 x 1/2 = 1/4, therefore your answer is A.

Starting average customer rating was 5.

Step-by-step explanation:

Equation representing the average customer rating at Austin's bakery over time is,

y = 0.25x + 5

Here, 'x' represents the time or duration.

Starting average customer rating means value of y at x = 0.

Therefore, y = 0.25(0) + 5

y = 5

Starting average customer rating was 5.

Answer:Starting average customer rating was 5.

Answer:

The chance of picking a yellow marble twice in a row without replacement is 0.22

Step-by-step explanation:

The given number of marbles in the bag = 25 marbles

The number of red marbles in the bag = 5 red marbles

The number of blue marbles in the bag = 8 blue marbles

The number of yellow marbles in the bag = 12 yellow marbles

The chance of picking a yellow marble = 12/25

The chance of picking another yellow when the first one is not replaced = 11/24

Therefore, the chance of picking a yellow marble twice in a row = 12/25 × 11/24 = 1/25 × 11/2 = 11/50

Therefore;

The chance of picking a yellow marble twice in a row without replacement = 11/50 = 0.22

Step-by-step explanation:

Total surface area of a sphere = 4πr²

Radius, r = 7x + 7

Total surface area of a sphere = 4πr²

= 4 * π * (7x + 7)²

= 4π * (7x + 7) * (7x + 7)

= 4π * 49x² + 49x + 49x + 49

= 4π * (49x² + 98x + 49)
