Step-by-step explanation:

Answer:

Smaller number: 12

Larger number: 34

Step-by-step explanation:

Let x represent the smaller number.

Let 3x - 2 represent the larger number (The larger number is two less than three times the smaller number, or x)

x + 3x -2 = 46

   Add 3x + x:

4x - 2 = 46

   Add 2 to both sides:

4x = 46 + 2

   Add 46 + 2:

4x = 48

    Divide both sides by 4:

4x/4 = 48/4

x = 12 is the smaller number

Since 12 is the smaller number, and the sum of the two numbers is 46, than the larger number must be 34.

I hope this helped you. If it did, please consider, rating, pressing thanks and/or giving my answer 'Brainliest.' Have a great day! :)

Answer:

y = 2x + 2

Step-by-step explanation:

given       : line passes through the points (4,10) and (9,20)

Required :  write a linear function in terms of x and y

solution   :

substitute the coordinate points into the equation: y = mx + b

(x=9, y=20)      _   20 = 9m + b

(x=4, y=10)            10 = 4m + b  

subtracting           10 = 5m

                               m = 10/5

                               m = 2

substitute x=2 back into eq.1 to solve for b

20 = 9m + b

20 = 9(2) + b

20 - 18 = b

b = 2

therefore the straight line equation is:

y = mx + b

y = 2x + 2

Answer:

Read left to right

Do parenthesis first

-4 ( 1 + 5) ^2

-4 (6) ^2

Then exponent

6^2 = 6 x 6 = 36

-4 x 36 = -144

Then divide

-144 / 6 = -24

Then the next parenthesis

(42+5) = 47

-24 - 47 = -71

Answer:

$2,184

Step-by-step explanation:

Simple interest = (Principal × Rate × Time) / 100

Principal = $6,500

Rate = 2.8%

Time = 12 years

Simple interest = (Principal × Rate × Time) / 100

= (6,500 × 2.8 × 12) / 100

= 218,400 / 100

= 2,184

Simple interest = $2,184

The simple interest on $6,500 at 2.8% for 12 years is $2,184

The equation represents the relationship between the number of raspberry smoothies and the number of strawberry smoothies Joel made

[tex]\frac{2}{3}x+\frac{3}{2}y=10[/tex]

Given :

Each raspberry smoothie uses 2/3 cup of yogurt , and each Strawberry smoothie uses 1 1/2 cups of yogurt Joel used a total of 10 cups of yogurt.

Let x represents number of raspberry and y represents the number of strawberry smoothies made.

Each raspberry smoothie uses [tex]\frac{2}{3}[/tex] cup of yogurt

x   raspberry smoothie uses [tex]\frac{2}{3} x[/tex] cup of yogurt

each Strawberry smoothie uses [tex]1\frac{1}{2} =\frac{3}{2}[/tex] cups of yogurt

y  Strawberry smoothie uses [tex]\frac{3}{2} y[/tex] cups of yogurt

Total of 10 cups of yogurt used

raspberry smoothie(yogurt) + strawberry smoothie (yogurt)=10 cups

[tex]\frac{2}{3}x+\frac{3}{2}y=10[/tex]

Answer:

? = 9

Step-by-step explanation:

you know 99 + 33 = 132 so you can substitute that: 132 = 11 (? + 3). im going to change ? into x for now: 132 = 11 (x + 3). then distribute the 11 so 132 = 11x + 33. then subtract 33 from both sides (99 = 11x) and divide both side by 11 (x = 9) and you get 9!

Step-by-step explanation:

Answer:

Inequalities are used to demonstrate relationships between numbers or expressions. An inequality describes a relationship between two different values.

The notation  

a

<

b

means that  

a

is strictly smaller in size than  

b

, while the notation  

a

>

b

means that  

a

is strictly greater than  

b

.

The notion  

a

≤

b

means that  

a

is less than or equal to  

b

, while the notation  

a

≥

b

means that  

a

is greater than or equal to  

b

.

Inequalities are particularly useful for solving problems involving minimum or maximum possible values.

Answer:

[tex] f(x) = 7x + 5 [/tex].

Step-by-step explanation:

The equation that represents the function can be written in the slope-intercept form, [tex] f(x) = mx + b [/tex].

To create an equation, we need to find the slope (m) and the y-intercept (b) of the function.

First, calculate the slope of the function using two points, (1, 12) and (2, 19).

[tex] slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{19 - 12}{2 - 1} = \frac{7}{1} = 7 [/tex]

Next, find b by substituting x = 1, f(x) = 12, and m = 7 into [tex] f(x) = mx + b [/tex].

[tex] 12 = (7)(1) + b [/tex]

[tex] 12 = 7 + b [/tex]

Subtract 7 from each side

[tex] 12 - 7 = b [/tex]

[tex] 5 = b [/tex]

[tex] b = 5 [/tex]

Substitute m = 7 and b = 5 into [tex] f(x) = mx + b [/tex].

✅Thus, the equation that represents the function would be:

[tex] f(x) = 7x + 5 [/tex].

Step-by-step explanation:

-7*7*16/8*14= -7*16/8*2=-7

Answer:

I can use variables to represent the coordinates of the vertices for a general triangle, ∆ABC. Then I can calculate the midpoints of the sides in terms of those variables. Using the point-slope formula for the equation of a straight line, I can build the symbolic equations for the three medians, AE, BF, and CD. I can solve for the point of intersection for two of the medians, AE and BF, for example. Finally, I can prove the lines (i.e., medians) concurrent if the point I found also satisfies the equation of the line for CD.
