Answer:

74.05

Step-by-step explanation:

1st step: plug -3.5 in for all values of x

y = 1/5(-3.5) + 7(-3.5)^2 - 11

2nd step: follow the order of operations by doing (-3.5)^2 to get 12.25

y = 1/5(-3.5) + 7(12.25) -11

3rd step: multiply 1/5 and -3.5 to get -0.7

y = -0.7 + 7(12.25) -11

4th step: multiply 7 and 12.25 to get 85.75

y = -0.7 + 85.75 - 11

Lastly, now that all operations are either addition or subtraction, work left to right

y = 85.05 - 11.00

y = 74.05

Answer:

3450 miles

Step-by-step explanation:

Multiply the number 17.25 by 200 since the boat is traveling for 200 hours and each hour is 17.25 miles to get 3450 miles which is your answer.

Answer:

[tex]\boxed {\boxed {\sf 3,450 \ miles}}[/tex]

Step-by-step explanation:

Distance can be found by multiply the speed by the time.

[tex]d=st[/tex]

Where d is the distance, s is the speed, and t is the time.

1. Define Variables

The speed is 17.25 miles per hour and the time is 200 hours.

[tex]s= 17.25 \ mi/hr[/tex]

[tex]t= 200 \ hr[/tex]

2. Calculate Speed

Substitute the values into the formula.

[tex]d=17.25 \ mi/hr * 200 \ hr[/tex]

Multiply. The hours (hr) will cancel each other out and leave miles as the units.

[tex]d=17.25 \ mi *200\\[/tex]

[tex]d=3450 \ mi[/tex]

The voyage was 3,450 miles

Step-by-step explanation:

for 1 book=480

for 4 books= 480×4

=1920

Answer:

If one book costs 480, then four books will cost the quadruplee. To calculate it, we can multiply by 4 the price of one book:

480 * 4 = 1920

So we know it wouldd cost 1920 rp to buy four.

Answer:

Solution is invalid

Step-by-step explanation:

Let the time when they will have the same water content be x hours

At x hours;

For the first tank, the content will be;

50 + 10x

For the second;

29 + 3x

Equating both, will give us x

29 + 3x = 50 + 10x

We will get x as a negative number here

Since number of hours can not be negative, the solution is invalid

When he played outside how many object did he fetch in all is 12+r

An expression is combination of variables, numbers and operators.

Given that Spot fetched 12 sticks and some rocks

Let the rocks be denoted as r

We need to check when he played outside how many object did he fetch in all

The number of sticks are 12

The number of rocks are r

They are asking for total which means we have to sum the number of sticks and number of rocks

12+r

Hence, when he played outside how many object did he fetch in all is 12+r

Answer:

x=2/3, y=0

Step-by-step explanation:

3x + 7y = 2,

6x - 5y = 4

Make the x coefficient the same in both equations.

3x + 7y = 2

(whole thing multiplied by 2)

6x + 14y = 4

Now subtract the equations to eliminate the x variable.

 6x + 14y = 4

-(6x - 5y   = 4)

        19y  = 0

           y = 0

Substitute 0 for y in one of the equations.

3x + 7(0) = 2

         3x = 2

           x = 2/3

Step-by-step explanation:

Answer:

x = 30

y = 7

Step-by-step explanation:

The triangle given is an equilateral triangle.

Equilateral Triangle

A triangle that has same length of all sides of triangle. They have same congruent internal angles as well.

So, If length of one side = 7

Length of other two sides will also be same i,e 7

Length of 2nd side = 7

Length of 3rd side = 7

Now, finding angles and value of x

The one angle is 2x, so the other two angles will be also 2x (because all angles of equilateral triangle are same)

We know that sum of all sides of angles of triagle = 180

We can write: [tex]2x+2x+2x=180[/tex]

Solving the equation to find x

[tex]2x+2x+2x=180\\6x=180\\x=180/6\\x=30[/tex]

So, x = 30

Since y is not given in picture, I think it is length of other sides i.e y = 7

Answer:

m = -60

b = 300

y = -60x + 300

Step-by-step explanation:

(0,300) and (5,0)

m = y2 - y1/x2 - x1

m = 0 - 300/5 - 0

m = -300/5

m = -60/1

m = -60

y-intercept = b = 300

slope intercept form: y = mx + b

y = mx + b

y = -60x + 300

Answer:

m = -60

b = 300

y = -60x + 300

Step-by-step explanation:

(0,300) and (5,0)

m = y2 - y1/x2 - x1

m = 0 - 300/5 - 0

m = -300/5

m = -60/1

m = -60

y-intercept = b = 300

slope intercept form: y = mx + b

y = mx + b

y = -60x + 300
