Answer:

-16.8

Step-by-step explanation:

The equation can be solved by performing the inverse of the operation that is done to the variable. Here, 12 is added to the variable. The inverse of that operation is addition of the "additive inverse", or "opposite" of 12:

12 + d = -4.8 . . . . . . given equation

12 -12 +d = -4.8 -12 . . . . . the same operation is done to both sides

d = -16.8

The value of d that makes the equation true is -16.8.

_____

The addition (subtraction) property of equality tells you that adding (subtracting) the same number from both sides of an equation will not change the value of the variable.

Answer:

d = 7.2

Step-by-step explanation:

12 + d = -4.8

subtract 12 from both sides and you get

d = 7.2

What is the x in 4x-5=8

ale4655 [162]

Answer:

x= 3.25

Step-by-step explanation:

4x-5=8

1. Take the -5 to the other side as a plus so now your question is

4x=13

2. to get the x by its self divide both sides by 4.

13 divided by 4 is 3.25

therefore x=3.25

He tables for f(x) and g(x) are shown below.

astra-53 [7]

Answer:

$(f - g)(5) = 16$

Step-by-step explanation:

Given

See attachment for tables

Required

$(f - g)(5)$

This is calculated as:

$(f - g)(5) = f(5) - g(5)$

From the table, we have:

$f(5) = 29;\ \ g(5) = 13$

So:

$(f - g)(5) = 29 - 13$

$(f - g)(5) = 16$

15 points!! Please help! please explain how you got you answers

Lynna [10]

We observe that a line will pass through 3 points, but to find a slope we only need two.

We see that it passes through points (assuming the scale of graph is 1 : 1) $P_1(x_1,y_1)=P_1(0,1)$ and $P_2(x_2,y_2)=P_2(2,-1)$ .

We can use slope formula that applies for any line and produce the same slope for any two different points on the line

$m=\dfrac{\Delta{y}}{\Delta{x}}=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{-1-1}{2-0}=-1$

So the slope is -1 also it intersects y-axis at $n=1$ so the general form of the linear function is

$f(x)=mx+n$

That is in your case

$\boxed{f(x)=-x+1}$

Hope this helps.
