Answer:

x = 14

Step-by-step explanation:

3x/-8 = -21/4

(3x/-8)×-8 =( -21/4)×-8

3x = 42

3x/3 = 42/3

x = 14

Answer:

x = 14

Step-by-step explanation:

to solve this you have to first move 3/-8 to the other side and divide while keeping x on the same side.

now to divide you must flip over 3/8 and multiply so 21/4 x 8/3 ( negative sign cross off because there are two of them) so 3 and 21 cross off leaving 7 in the numerator 4 and 8 cross of leaving 2 in the numerator and then 7 and 2 get multiplied and you will get 14.

3x-8<23 and -4x+26>6
Papessa [141]

Answer:

3x-8<23 and -4x+26>6

x<31/3            x<5

Step-by-step explanation:

3x-8<23

Add 8 to both sides

3x<31

Then divide 3 to both sides

x<31/3


and -4x+26>6

Minus 26 to both sides

-4x>-20

You divide -4 to both sides

Keep in mind that everytime you divide a negative the inequality will change so > will be <

x<5

What is the sequence of second differences for ax +b?
MAVERICK [17]

Answer:

ZERO

Step-by-step explanation  

Write the given function as

F(x) = ax + b

i.e Y = ax + b

now differentiate Y with respect to X

dY/dX = d (ax + b)/ dx

dY/dX = a

now again differentiate this function with respect to x

so,  d^2Y/dX^2 = d^2 (a)/dX^2

                         = 0 (ZERO)

note: differentiation of constant function is zero

Arby’s sells brisket last year there was drought and farmers were able to raise fewer cows is this a change in supply or demand
kiruha [24]

This is a change in both supply and demand. Due to farmers raising fewer cows the supply of cows goes down. Because there is more of a need of cows due to the shortage the demand or need for them goes up. Due to the limited amount of cows and the high demand prices will go up.

Which lists all of the y-intercepts of the continuous function in the table?
Rainbow [258]

Answer:

A (0,0)

Step-by-step explanation:

When a function intersects the y-axis then the point of intersection is called y-intercept of the function,

Also, for y-intercept x = 0.

That is, if f(x) is the function then its y-intercept is (0, f(0) )

By the given table for x = 0, f(x) = 0

Hence, the y-intercept of the given function is (0,0),

Option A is correct.
