Find the range of this equation

Complete question :

A fish is swimming at a constant rate toward the ocean floor. The equation y = -7x - 3 can be used to represent this situation, where y is the depth of the fish in meters below sea level and x is the number of seconds the fish has been swimming

Which statement best describes the depth of the fish

From a starting position of 7 meters below sea level, the fish is descending 3 meters per second.

From a starting position of 7 meters below sea level, the fish is ascending 3 meters per second.

From a starting position of 3 meters below sea level, the fish is descending 7 meters per second.

From a starting position of 3 meters below sea level, the fish is ascending 7 meters per second.

Answer:

From a starting position of 3 meters below sea level, the fish is descending 7 meters per second.

Step-by-step explanation:

Given the equation :

y = - 7x - 3

y = depth of fish in meters ; x = Number of seconds fish has been swimming

From the equation ; which is written according to the slope - intercept equation, ; y = mx + c

The slope, m = - 7 is the rate of change in y per unit of x

c = intercept, constant, value of y when x = 0

Hence, the true statement in the equation is :

-7 represents descent and meams fish descents at a rate of 7 m per second

At x = 0, the fish is at a depth of 3 m

Answer:

48

Step-by-step explanation:

80 over 100*150

80 divided by 100=0.8 *150=1208student

0.8 *60 = 48

Answer:

45%

Step-by-step explanation:

25% is the same as .25. By taking .25 times 180 you get 45 or 45%.

Answer:

990

Do 100+890

its simple math

The number that is one hundred more than 890 would be,

⇒ 990

The process of combining two or more numbers is called the Addition. The 4 main properties of addition are commutative, associative, distributive, and additive identity.

Given that,

To find a number that is one hundred more than 890.

Let us assume that,

The number that is one hundred more than 890 = x

Hence, it can be written as,

⇒ x = 890 + 100

Solve for x,

⇒ x = 990

Therefore, the number that is one hundred more than 890 = 990

Answer:

y=0x - 4

Step-by-step explanation:

perpendicular to the y-axis means parallel to the x-axis.

that would be a horizontal line and they have no slope. so m=0

(0, -4) is the y-intercept since the y intercept is when x is zero.

b=-4

y=mx+b

y=0x - 4

Answer:

(y − 9) (y − 2)

Step-by-step explanation:

Factor  y^2 − 11y + 18 using the AC method.

(y − 9) (y − 2)

The “AC” method or factoring by grouping is a technique used to factor trinomials. A trinomial is a mathematical expression that consists of three terms.

Answer:

the missing side is √65

Step-by-step explanation:

a^2 + b^2 = c^2

4^2 + 7^2 = c^2

16 + 49 = c^2

65 = c^2

√65 = √c^2

√65 = c

Answer:

Here,

x + 25° + 3x + 95° + 80°=360° (Sum of angles of a quadrilateral is 360°)

or,x+3x + 25° + 95° + 80° =360°

or,4x + 200 = 360°

or,4x = 360 - 200

or,4x = 160

or,x = 160÷4

or,x = 40

Now,

Angle K = (x + 25)° = 40 + 25° = 65°

Angle L = 3x° = 3 × 40° = 120°

Answer:

The answer should be A

Step-by-step explanation:

y=3x+2

First, check the y-intercept, which is 2 in this case. Only A, B, and D crosses the y-axis at 2.

Next, check the slope (I didn't calculate every one of the slopes)

the slope, from the equation is 3, so the graph should be positive (left to right always)

Only graph A has a positive slope and a y-intercept of 2.

The value of n is 2.

Step-by-step explanation:

The total number of people in the choir = 60

Number of  women in the choir = 30

Let the number of men in the choir be represented by x, so that;

Number of women = 3x

So that;

3x = 30

x = [tex]\frac{30}{3}[/tex]

 = 10

The number of men in the choir is 10.

the number of children in the choir: the number of men in the choir = n:1

number of children in the choir = 60 - (number of women + number of men)

                                                    = 60 - 40

                                                    = 20

number of children in the choir = 20

Thus,

the number of children in the choir: the number of men in the choir = 20:10

                                                            = 2:1

The value of n is 2.

Answer:

20 men in the choir and 40 children

Answer:

The new granite countertop will cost $824.

Step-by-step explanation:

Step 1: The problem is to determine how many yards per square that the countertop is made up of.

This is the equivalent of finding the square area of the countertop.

The formula for the square area of a rectangle is given as L x W.

Where L = Lenght which is equal to 3 yards

W = 1 yard

Step 2:

Cost of per square yard required therefore is

3 x 1 = 3 square Yards.

The granite required for the countertop project therefore will cost:

$206 x 3 = $824.00

52[tex]\pi[/tex]

Step-by-step explanation:

The total shaded are will be the area of big circle - not shaded circle + little shaded circle.

The are of big shaded circle: [tex]\pi[/tex][tex]r^{2}[/tex] So, A=[tex]\pi[/tex](8^2)= 64[tex]\pi[/tex]

The are of not shaded circle: [tex]\pi r^{2}[/tex] So, A= [tex]\pi[/tex](4^2)= 16[tex]\pi[/tex]

The are of little shaded cirlce: [tex]\pi r^{2}[/tex] So, A=[tex]\pi[/tex](2^2)= 4[tex]\pi[/tex]

64[tex]\pi[/tex] - 16[tex]\pi[/tex] + 4[tex]\pi[/tex]= 52[tex]\pi[/tex]

Answer:

JL is 111 miles

Step-by-step explanation:

When we talk of round trips, we mean the distance going plus the distance coming

To get the actual distance between the two places, we need to divide by 2

K to L is round trip 548 miles

K to L distance is 548/2 = 274 miles

K to J round trip is 326 miles

K to J distance is 326/2 = 163 miles

From what we have ;

KL = KJ + JL

274 = 163 + JL

JL = 274-163

JL = 111 miles

To justify our answer, we can see that J is between K and L

if we added the distance KJ and JL, we should get the distance KL

from the calculations we have made, we can see that this is correct and our answer is justified

Given:

Cost of lunch = $40

Rate of sales tax = 15%

Rate of tip = 20% on $40.

To find:

The amount Damon pay.

Solution:

We have,

Cost of lunch = $40

Rate of sales tax = 15%

[tex]\text{Sales tax}=\dfrac{15}{100}\times 40[/tex]

[tex]\text{Sales tax}=6[/tex]

Rate of tip = 20% on $40

[tex]\text{Tip}=\dfrac{20}{100}\times 40[/tex]

[tex]\text{Tip}=8[/tex]

Now,

Total amount = Amount + Sales tax + Tip

                      = [tex]40+6+8[/tex]

                      = [tex]54[/tex]

Therefore, Damon pays total $54.
