Answer:

Step-by-step explanation:

In the equation ...

  y = x² +3

the largest variable exponent is 2, which is not 1. The equation is not linear.

__

In the equation ...

  y = (1/4)x +7

the largest variable exponent is 1, so the equation is linear.

Answer:

C. 1/8

Step-by-step explanation:

Dimensions of the Original Box:

Length = 40 inches

Width = 20 inches

Height = 8 inches

Volume of original box = L*W*H = 40*20*8 = 6,400 in³

Dimensions of the New Box (½ of the dimensions of the original box):

Length = ½*40 = 20 in

Width = ½*20 = 10 in

Height = ½*8 = 4 in

Volume of original box = L*W*H = 20*10*4 = 800 in³

Constant of proportionality between the volume of the new box and the volume of the original box = [tex] \frac{800}{6,400} = \frac{1}{8} [/tex]

Answer:

1) b. 1.562x10⁸

2) a. 4.8x10⁶

4) d. 2.3x10³

5) a. 4.21x10 -⁶

6) 6.6835x10⁵

Step-by-step explanation:

1) (2.2x10⁴)•(7.1x10³)= 156200000

2) 9.6x10⁹÷2x10³= 4800000

4) 6.9x10⁸= 2300

5) 5.6x10 -⁷ + 3.65x10 -⁶= 4.21x10 -⁶

6) 6.72x10⁵ - 3.65x10³= 668350

Answer:

84.3

Step-by-step explanation:

843 ÷ 10

The place value of 843 is

8 = Hundreds

4 = Tens

3 = Units or ones

Hence,

843 ÷ 10

= 843/10

= 84.3

Step-by-step explanation:

Answer:

y = 11t + 8

Step-by-step explanation:

Since the starting fee is 8 dollars and the additional costs are 11 dollars per ticket, you can write the equation as:

y = 11t + 8

Where "t" represents the amount of tickets bought.

Answer:

X = -16.75

Step-by-step explanation:

Distribute.

(x + 12)23 = 23x + 276

12 + 5x -1 = 11 + 5x

Combine like terms.

23x - 2x - 5x = 16x

11 - (276 + 3+16 ) = -284

16x = -284

x = -17.75

Answer:

c.  (-4, 4)

Step-by-step explanation:

y = 0.8x + 7.2

20x + 32y = 48

20x + 32y = 48

20x + 32(0.8x + 7.2) = 48

20x + 25.6x + 230.4 = 48

45.6x + 230.4 = 48

45.6x = -182.4

x = -4

y = 0.8x + 7.2

y = 0.8(-4) + 7.2

y = -3.2 + 7.2

y = 4

Thank you ☺️

Answer:

Step-by-step explanation:

Given the function  f(x)=-x+1,x<0 and f(x) = x^2-1,x>0

when x = 4

f(4) =  -4+1

f(4) =  -3

Also f(4) = 4^2 -1

f(4) = 8-1

f(4) = 7

when x = -1

f(-1) =  -(-1)+1

f(-1) =  2

Also f(-1) = (-1)^2 -1

f(-1) = 1-1

f(-1) = 0

when x = -2

f(-2) =  -(-2)+1

f(-2) =  3

Also f(-2) = (-2)^2 -1

f(-2) = 4-1

f(-2) = 3

when x = 1

f(1) =  -1)+1

f(1) =  -2

Also f(1) = (1)^2 -1

f(1) = 1-1

f(1) = 0

From the calculation above, the correct statements are

A. F(4)=7

B f(-1)=2  

d. F(1)=0

Answer:

y = 150x + 200

Step-by-step explanation:

Given the table :

Week (x) __ 0 ____ 1 ____ 2 ____3 _____ 4

Balance(y) :$200_ $350_ $500_ $650_ $800

Equation in slope - intercept form:

y = mx + c

Where

x and y are the independent(x) and dependent variables (y)

C = intercept, value of y, when x = 0

m = gradient change in y per change in x

Hence,

c = $200 ; y value when x = 0

m = change in x / change in y

m = (500 - 350) / ( 2 - 1)

m = $150

Hence, equation becomes :

y = 150x + 200

Answer:

13000

Step-by-step explanation:

because 851 is above 500 you add 1 to the 2 then put 000 for the other numbers

Answer:An important category of percentage exercises is markup and markdown problems. For these, you calculate the markup or markdown in absolute terms (you find by how much the quantity changed), and then you calculate the percent change relative to the original value. So they're really just another form of "increase - decrease" exercises.

Answer:

1+18-11+16

Step-by-step explanation:

if the elevator went up it will be plus but if the elevator came down it will be minus and then you will get 1+18 because it went up and then it go down 11 floor and it will be 1+18-11 and then it went up again 16 floor so the last answer will be 1+18-11+16
