Jennifer's bank account is modeled by the following equation where equals the number of months and y equals the balance: y = 24x + 50

We can solve this problem in three steps.

1) find the area of the square

[tex]a=lw\\\\a=(7.5)(6)\\\\a=45ft^{2}[/tex]

2) find the area of the triangle

[tex]a=\frac{1}{2}bh\\\\a=\frac{1}{2} (6)(4)\\\\a=12ft^{2}[/tex]

3) add the areas together

[tex]a=45+12[/tex]

a = 57 ft²

Step-by-step explanation:            

let angles be 3x, 5x, 10x

3x+5x+10x=180(angle sum property)

18x=180

x=180/18

x=10

therefore, angles are 3*10=30

5*10=50

10*10=100..

Answer: -3/4 is greater

Step-by-step explanation:

If you plot the fractions on a number line, -6/4 would be farther left than -3/4, meaning -3/4 is a bigger number.

One of the ways to solve a system of equation is by using the substitution method

The values of x and y are -9 and 5

The equations are given as:

2x + 6y = 12

x + y = -4

Make x the subject in the second equation

x = -4 - y

Substitute x = -4 - y in the first equation

2(-4 - y) + 6y = 12

Expand

-8 - 2y + 6y = 12

Add 8 to both sides

- 2y + 6y = 20

So, we have:

4y =20

Divide through by 4

y = 5

Recall that:

x = -4 - y

So, we have:

x = -4 - 5

x = -9

Hence, the values of x and y are -9 and 5

Step-by-step explanation:

The sine inverse of 1 is 90

Answer:

sin 90° = 1 is a true statement.

Step-by-step explanation:

Answer:

Area of square field = 900 m²

To find :

Time to take 10 round with the speed of 6 km/h

Now, firstly we'll find the distance for one round which is perimeter of the square field.

=> Perimeter = 4 × side.

We'll find side the helps of area

=> Area = 900 m²

=> Side × Side = 900

=> Side = √900

=> Side = 30 m

Now, perimeter of the field

=> Perimeter = 4 × 30

=> Perimeter = 120 m

Now, he have to take 10 round,. so distance covered in 10 round will be 10 × distance in one round

=> Total distance = 10 × 120

=> Total distance = 1200 m

Now we'll find time

=> Time = Distance/speed

Now the distance is in meter and we have to convert it in Km

=> 1200 m = 1200/1000 km

=> 1200 m = 1.2 km

Now putting all the values

=> Time = Distance/speed

=> Time = 1.2 / 6

=> Time = 0.2 hour

Or

=> Time = 0.2 × 3600 seconds

=> Time = 720 seconds.

Answer:

y = 4, x=1 or x=110

Step-by-step explanation:

1. 4y-2=18                      2. x/2+5=11

       -2  -2                         x/10=11

4y = 16                               x=1

4y/4 = 16/4                         or

y=4                                  x/10=11

                                       0.1x=11

                                        0.1x/0.1 = 11/0.1

Answer: y= 3x-1

Step-by-step explanation:

Equation of a straight line:

y = mx + b ------(i)

Step by Step Solution:

Step 1: Calculating Slope (m).

m =

y2-y1

x2-x1

m =

2--1

1-0

m =

3

1

m = 3

Now putting value of m in equation (i)

y = 3x + b -----(ii)

Step 2: Calculating Y-intercept (b).

Lets choose the first point, (0,-1) for calculating y-intercept:

y = mx + b

-1 = 3(0) + b

-1 = 0 + b

-1 = b

b = -1

Answer:

y=3x-1

Step-by-step explanation:

Hi there!
We are given a line, and we want to find the equation of that line in slope intercept form

Slope-intercept form is given as y=mx+b, where m is the slope, and b is the y intercept

First, we need to find the slope of the line

The slope of the line can be calculated from 2 points with the equation [tex]\frac{y_2-y_1}{x_2-x_1}[/tex], where [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex] are points

We can take any 2 points from the line to help us; for example, we can take (0,-1), and (1,2), which are both on the line

We can label the values of the points to avoid confusion while we calculate the slope:
[tex]x_1=0\\y_1=-1\\x_2=1\\y_2=2[/tex]
Now let's plug these values into the formula to solve for the slope:

m=[tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

m=[tex]\frac{2--1}{1-0}[/tex]

Simplify:

m=[tex]\frac{2+1}{1-0}[/tex]

Add/subtract:

m=[tex]\frac{3}{1}[/tex]

m=3

The slope of the line is 3
Remember that our equation is y=mx+b; we can plug 3 as m into the equation right now.

This is our equation so far:

y=3x+b

Now we need to find b
The y intercept (b) is the point in where the line intersects with the y axis; the value of x is 0 at that point

Since we have the graph given, we can find the value of the y intercept by finding the point that crosses (intersects) the y axis.

That point would be (0, -1)

The value of b is simply the value of y at this point; in this case, the value of b is -1

So plug -1 as b into the equation:

y=3x-1

Hope this helps!

Answer :

A) y = 7x + 4

Step-by-step explanation:

we need to see the equations 1 by 1

instead of y and x we need to put the value given

I am taking the last x and yes values as they are small numbers and will be easy to calculate

x = -1

y = -3

placing the values in equation :

A) y = 7x + 4

-3 = 7 × -1 + 4

-3 = -7 + 4

-3 = -3

So we got the answer same ! so the correct answer will be A) y = 7x + 4

let's check other one too to confirm overselves

b) y = 4x + 7

-3 = 4 × -1 + 7

-3 = -4 + 7
