Answer:

2, 3

Step-by-step explanation:

Answer:

y = mx + b

Since it is perpendicular to the given line, its slope is the negative reciprocal of the slope of the given line.

Slope of given line:

m0 = -a/b = -(-3) / (1) = 3

Slope of perpendicular line:

m = -1/3

y = (-1/3)x + b

Use the given point to find b.

2 = (-1/3)(3) + b

2 = -1 + b

b = 3

y = (-1/3)x + 3

Step-by-step explanation:

Answer:

Step-by-step explanation:

Perpendicular lines have their slope negative reciprocal

y= -3x +3 has the slope -3

y = (1/3)x +b is the line that is ⊥ so it has the slope (1/3)

The line passes trough the point (x=-2, y=8) so substitute the x and y to find b

8 = (1/3)(-2) +b, multiply (1/3)(-2) = -2/3 and add 2/3 on both sides

8+(2/3) = b, find the common denominator and add the fractions

[(3*8)+2 ]/3 =b

(26/3)  = b

The equation of the line described is y= (1/3)x +(26/3)

BIDMAS

Step-by-step explanation:

In order to solve equations correctly, we use BIDMAS ( Brackets, Indices, Division, Multiplication, Addition and Subtraction).

For example, if we have 5+2x7, we would multiply 2 by 7 first, then add 5 to the value.

Answer: 25 miles per hour

Step-by-step explanation:

Speed=Distance/Time

The distance is 150, and the time is 6. So, all we need to do is divide 150 by 6, and we get 25 miles per hour. Hope this helped!

Answer:

Step-by-step explanation:

r = d/t

d = 150 miles

t = 6 hours

r = 150 / 6

r = 25 miles / hour

Answer:

An expression that represents repeated multiplication of the same factor is called a power. The number 5 is called the base, and the number 2 is called the exponent. The exponent corresponds to the number of times the base is used as a factor.

Answer:

Step-by-step explanation:

Out of 30 numbers, half is multiple of 2 and the third is multiple of 3.

We have 15 even numbers and 10 multiples of 3. Out of 10, half is even numbers and  therefore counted twice.

So we subtract 5 to get:

Answer:

x = - [tex]\frac{15}{16}[/tex]

Step-by-step explanation:

2 + [tex]\frac{x}{5}[/tex] + x = [tex]\frac{7}{8}[/tex]

Multiply through by 40 ( the LCM of 5 and 8 ) to clear the fractions

80 + 8x + 40x = 35

48x + 80 = 35 ( subtract 80 from both sides )

48x = - 45 ( divide both sides by 48 )

x = - [tex]\frac{45}{48}[/tex] = - [tex]\frac{15}{16}[/tex]

Answer:

The number of bags bought by Javier will be 2.

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.

Given that Javier bought three more bags of Reese's than lollipops and two fewer bags of starburst than lollipops. bags of lollipops cost $3.75 each, bags of Reese's cost $5.50 each, and bags of starburst cost $4.25 each. He spends a total of $48.50.

From the equations and solve them to get the number of lollypops.

R = L+3

L = S - 2

The equation for total cost will be,

3.75L + 5.5R + 4.25S = 48.5

3.75( s - 2) + 5.5( S + 1) + 4.25S

3.75S - 7.5 + 5.50S + 5.5 + 4.25 S = 48.5

13.5S = 48.5 + 2

13.5S = 50.2

S = 4

The number of lollypops will be,

L = S - 2

L = 4 - 2

L = 2

Therefore, the number of bags bought by Javier will be 2.

Answer:

Antonia saved $5.39

Step-by-step explanation:

Candle:

$9.59 - $0.50 (coupon) = $9.09

Towel:

$21.43 - $2.75 (coupon) = $18.68

Dishes:

$21.43 x 10% = 2.143

$21.43 - $2.143 = $19.287, rounded to the nearest cent and it’s $19.29.

Calculate the amount of money saved by adding 0.50 + 2.75 + 2.143, which is 5.393. Round to the nearest cent and it will be $5.39.

Answer:

P=145.8m

Step-by-step explanation:

Answer: The perimeter is 145.8 square meters

Step-by-step explanation:

Area=513.5 square meters

513.5=l (length) times w (width)

513.5= 7.9 times w

513.5= 7.9w

(DIVIDE 513.5 AND 7.9 BY 7.9)

65= w

Perimeter= 2l + 2w

Perimeter=2(7.9) + 2(65)

Perimeter=15.8 + 130

Perimeter=145.8 square meters

Thus, the linear equation models the increase in the price of a loaf of bread will be 50x+12=70.

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

It is given that, the average cost of a loaf of bread in 1950 was approximately 12 cents, and by 1990 the cost was about 70 cents.

(Let x represent the number of years since 1900.)

The linear equation models the increase in the price of a loaf of bread will be.

y = bx + +c

70 = 50x + 12

The linear equation models the increase in the price of a loaf of bread will be 50x+12=70.
