Answer:

Left: yes it is linear

Right: No it is not.

Step-by-step explanation:

Left Problem

The table on the left is linear. It's general form is

y = 6x + 7

x = 5

y = 5*6 + 7

y = 37

-------------------

x = 8

y = 6*8 + 7

y = 48 + 7

y = 55

------------------

y = 6*12 + 7

y = 72 + 7

y = 79

=============

Right Problem

The right problem looks like it is linear. It is not, I don't think. Do the same thing you did above.

y = 62x

x = 2

y = 2*62

y = 124

-----------------------

y = 62x

x = 6

y = 62 * 6

y = 372

---------------------

y = 62*x

x = 9

y = 62 * 9

y = 558            

It should be 558 not 552

Alex is y years old. Bella is 4 years older than him .Carla is double Alex's age. The sum total of their age is 32
Form and solve an equation to work out the ages of the three children

Answers

Answer:

Alex is 7, Bella is 11, and Carla is 14

Step-by-step explanation:

Equation is 32=y+2y+(y+4)

To solve:

First combine like terms (the y's)

32=4y+4

Subtract 4 from both sides

28=4y

Divide both sides by 4 to get y alone

7 =y (Alex's age)

Bella is 4 years older than Alex so 7+4 = 11

Carla is 2 times older than Alex so 2 • 7 = 14

Their ages are supposed to add up to 32.

7+11+14

18+14

32

Two triangles can be formed with the given information. Use the Law of Sines to solve the triangles
A = 59°, a = 13, b = 14

Answers

angle A = 59o and sides a = 13, b = 14.
Lets find remaining angles are B and C and the remaining side c.
Law of sines : a/sinA = b/sinB ⇒ sinB = (b*sinA)/a
sinB = (14*sin59o)/13 = (14*0.857167)/13 ≅ 0.923
B ≅ sin-1(0.923) ≅ 67.384.
There are two triangles, B₁ = 67.4 and B₂ = 180 - 67.4 = 112.6
find the angle c for B₁ = 67.4
A+ B +C = 180.
Angle C = 180 - (59 + 67.4) = 53.6.
Law of sines : b/sinB = c/sinC ⇒ c = b*sinC/sinB
c = (14)*sin(53.6)/sin(67.4) = (14)*(0.805)/(0.923) = 12.21.

find the angle c for B₂ = 112.6
A+ B +C = 180.
Angle C = 180 - (59 + 112.6) = 8.4.
Law of sines : b/sinB = c/sinC ⇒ c = b*sinC/sinB
c = (14)*sin(8.4)/sin(112.6) = (14)*(0.146)/(0.9232) = 2.27.

Answer:

67.4°, C = 53.6°, c = 12.2; B = 112.6°, C = 8.4°, c = 2.2

a/sinA=b/sinB=c/sinC

a/sinA=13/0.8572=15.1662

sinB=b/a *sinA

sinB=14/13 *sin59=0.9231

B=67.4

B1=90+22.6=112.6

because sin67.4=sin112.6=0.9231

C=180-59-67.4=53.6

C1=180-59-112.6=8.4

c=a* sinC/sinA=13* sin53.6/sin59=12.2

c1=a* sinC1/sin59=13*sin8.4/sin59=2.2

A whale can stay underwater 7 times as long as x minutes more than a platypus can. Write an equation that states the relationship of the minutes these two mammals can stay underwater

Answers

Answer:

Step-by-step explanation:

Using the information provided we can create the following two equations each of which calculates the total number of minutes that the whale (w) or the platypus (p) can stay underwater. In order to solve each, you would need the value of at least 1 of the mammals.

w = 7 * (p+x)

p = (w / 7) - x

The w in these equations represents the number of minutes the whale can stay underwater while the p represents the number of minutes that the platypus can stay underwater.

A rectangle measures 2 1/3 inches by 1 2/3 inches. What is its area?

Answers

Answer:

35/9 inches

Step-by-step explanation:

you can put this in a mixed fraction, its still correct:

3 8/9

The area of the rectangle is 35/9 square inches.

What is a rectangle?

A rectangle is a 2-D shape with length and width.

The length and width are different.

If the length and width are not different then it is a square.

The area of a rectangle is given as:

Area = Length x width

We have,

To find the area of a rectangle,

We multiply the length by the width.

Length = 2 1/3 = 7/3 inches

Width = 1 2/3 = 5/3 inches

Area = Length x Width

Area = (7/3) x (5/3)

Area = 35/9 square inches

Therefore,

The area of the rectangle is 35/9 square inches.

Zahn takes a summer job selling ice cream bars at the pool. He receives a fixed salary and then additionally a commission for each ice cream bar he sells. The table shows Max's total earnings, y, in dollars, from selling x ice cream bars:

a

b

c
y = 4x + 42


d
y = x + 42


Answers

Answer: B

If you look at the table, you notice that he earns 30 without selling ice cream bars. This is his fixed salary.

When he sells one ice cream bar, he earns 34, which means he gets 4 dollars for each bar he sells.

The equation that best represents the relationship between x and y is b) y = 4x + 30, because 4 dollars × number of ice cream bars + fixed salary equals his total earnings.

Linear function definition: a function that will create a straight line when graphed.

11 is not a linear function (not a straight line), but 12 is.

For the tables, you can either plot out the graph or just look at the number patterns. A linear function's numbers will always increase/decrease accordingly at a constant rate. For example, in 14, you notice that as x increases by 1, y decreases by 2. This means it is a linear graph.

In 13, as x increases by 1, the output y increases but at a different rate each time. It increased by 3 at first, then 5, then 7. Hence, it is not a linear function. What is it then? It is an exponential function.

What is the equation of the line that passes through (-3, -1) and has a slope of 3/5 ? Put your answer in slope-intercept form.

y = 3/5x + 4/5
y = -3/5 x - 4/5
y = 3/5x - 4/5

Answers

Answer:y=3/5x+4/5A

I hoped this helped

THE ANSWER IS: y = 3/5 + 4/5

first plug the slope and the given point into point-slope from: (y-y1) = m (x-x1)
m=slope= 3/5
point=(x1,y1) = (-3,-1)

(y+1) = 3/5 (x+3)
solve for y to get slope-intercept form
y+1 = 3/5x + 9/5
y = 3/5x + 4/5
