Answer:

Answer in explanation

Step-by-step explanation:

We can use a number line to explain this subtraction.

The first thing to do is to locate the number 7 on the number line. This should be located to the right of the number line.

Then, since we are subtracting, we need to count left from the position of interest. So we will count 12 integers to the left of 7.

If things are right, we would land at -5

If it was a case of addition, we will need to keep counting right from the position of origin

Liono4ka [1.6K]

Answer:

7/11

Step-by-step explanation:

- 11 =  \frac{ - 7}{y}

=  >  - 11y =  - 7

=  > y =  \frac{ - 7}{ - 11}

=  > y =  \frac{7}{11} (ans)

Sheldon needs to buy 8 gallons of ice cream,
kolbaska11 [484]

Answer:

The <u>larger </u>size container and the Cold farms is the better deal for Sheldon.

Step-by-step explanation:

Given:

1 gallon = 8 pints

2.50 \times 8 =20

Multiply  the gallons to 20

8 × 20 = 160

Then, the large size is 18.

4.50 ×4 =18 (1 Gallon= 4 quartz)

Therefore, the <u>larger </u>size container and the Cold farms is the better deal for Sheldon.

7 - r/8 - 3d <br><br><br><br> Variables <br><br> r=32 and d= 2
satela [25.4K]

The required value if r = 32 and d = 2 is -3

Given the expression

7-\frac{r}{8} - 3d

Substituting the given variables

r = 32

d = 2

The expression becomes

= 7-\frac{32}{8} - 3(2)\\= 7 - 4 - 6\\= 3 - 6\\= -3

Hence the required value is -3

Sketch the curve represented by the parametric equations (indicate the orientation of the curve), and write the corresponding re
raketka [301]

Answer:

(See explanation below for further details).

Step-by-step explanation:

Let be a parametric curve represented by x = 3\cdot t - 5 and y = 5\cdot t + 1, where t is the parametric variable.

The curve is represented graphically with the help of a graphing tool, whose outcome is included in the image attached below. The corresponding rectangular equation is found by eliminating t of each equation.

t = \frac{x+5}{3} and t = \frac{y-1}{5}

\frac{x+5}{3} = \frac{y-1}{5}

5\cdot (x+5) = 3\cdot (y-1)

5\cdot x +25 = 3\cdot y - 3

5\cdot x -3\cdot y = -28

The parametric equations represents a linear function (first-order polynomial).

If an object is projected upward from ground level with an initial velocity of 128 ft per sec, then it's height in feet after t
antoniya [11.8K]

Answer: t= 4 seconds

Maximum height = 256 feet

Step-by-step explanation:

The height of the object projected upwards after t seconds is given by

s(t)=-16t^2+128t.

The expression is a quadratic equation. When this equation is plotted on a graph, height against time, it takes the shape of a parabola whose vertex represents the maximum height attained by the object.

To get the value of t at the maximum height,

t = -b/2a

From the equation,

a = -16

b = 128

t = -128/-2×-16

= -128 /- 32= 4

it will take 4 seconds to reach its maximum height

To find maximum height attained, put t= 4 in the equation

s(t)=-16t^2+128t

S = -16× 4^2 + 128×4

S = -256+512

S = 256 feet
