how do you solve 8 = 3r - 1

Answers

Answer 1

add 1 to both sides then divide by 3. the answer should be r=3

Answer 2

Answer:

r=3

Step-by-step explanation:

First, you would add 1 to both sides so:8+1=3r-1+1 so that gives you 9=3r.

Then, you divide 3 from both sides. 9/3=3r/3 so that gives you r=3

Find the x and y intercepts of the line

Answers

Answer:

x-intercept=1/4     y-intercept= -1/8

Step-by-step explanation:

First, simplify the equation, y= 1/2x-1/8

Then you want to graph the equation with a slope of positive 1/2 starting at -1/8 that'll intercept across the x-axis at 1/4.

To find the y-intercept, you simply have to keep in mind that y=mx+b

b=y-intercept

So our y-intercept is stated in the equation after we simplified it

Answer:

To write .010 as a fraction you have to write .010 as numerator and put 1 as the denominator. Now you multiply numerator and denominator by 10 as long as you get in numerator the whole number.

.010 = .010/1 = 0.1/10 = 1/100

And finally we have:

Step-by-step explanation: 4 times 3 is 12    5 times 3 is 15            6 times 3 is 18 and       7  times 3 is 21

Answer:

It will probably be y = 3(x)

so let's take the first example

x = 4

so use the rule

y = 3(x)

y = 3(4)

y = 3 x 4

y = 12

that's how y became 12.

So use the rule : y = 3(x)

Ryan deposits $775 in an account that pays 1.24% simple interest for 4 years.
Brian deposits $775 in an account that pays 1.24% simple interest for 1 year

How much interest did Ryan's account earn the first year?

Answers

Answer:

19.22 US$

and

38.44 US$

Step-by-step explanation:

The interest Ryan's account earned for the first year is $9.61.

What is Simple Interest?

Simple interest is based on the principal amount of a loan or the first deposit in a savings account.

Mathematically,

SI = PRT/100

here, P is principle amount, R is the rate and T is the time.

Now it is given that,

Principle deposited by Ryan, P = $775

Interest, R = 1.24%

Time, T = 4 years

And for Brian,

Principle, P = $775

Interest, R = 1.24%

Time, T = 1 year

And Simple Interest for Ryan for 1st year,

SI = PRT/100

⇒ SI = (775*1.24*1)/100

⇒ SI = $9.61

Thus, The interest Ryan's account earned for the first year is $9.61.

The given trapezoid is WXYZ. Now, in a trapezoid, one pair of opposite sides are usually parallel. Parallel lines have same slope and slope of line parallel to x axis is 0.

Now, If the line starts at the bottom left and goes towards the top right it means there is a negative slope. Thus, the true statments for Trapezoid WXYZ are:

- Line WZ has the same slope as line XY.

- Line XW has a lesser slope than line YZ.

- Line ZW has the same y-intercept as line WZ.

- Line XY has a greater y-intercept

∠K RQ = 115

Step-by-step explanation:

1st step is to get the internal ∠R

R + P + Q = 180R + 50 + 30 = 180R = 180 - 50 - 30R = 100

to get the angle ∠K RQ (same as step 1)

K + R + Q = 180K + (100/2) + 15 = 180K = 180 - 50 - 15K = 115

therefore, the angle ∠K RQ = 115

–0.4|x + 5.75| – 4.3 = –8.7

Answers

5.25, -16.75
I think it’s wrong

The solution to the absolute value equation –0.4|x + 5.75| – 4.3 = –8.7 is

x  =  -16.75  or  x  =  5.25

The given absolute value equation is:

–0.4|x + 5.75| – 4.3 = –8.7

Collect like terms

–0.4|x + 5.75| = –8.7 +  4.3

–0.4|x + 5.75|   =  -4.4

Divide both sides by -0.4

|x + 5.75|  =  -4.4  / -0.4

|x + 5.75|  =  11

x  +  5.75  =  11

x   =  11  -  5.75

x   =   5.25

x  +  5.75  =  -11

x   =  -11  -  5.75

x   =  -16.75

The solution to the absolute value equation –0.4|x + 5.75| – 4.3 = –8.7 is

x  =  -16.75  or  x  =  5.25

The attributes of EMPLOYEE include Employee ID (identifier), Name, Address, and Birthdate. The company also has several projects. Attributes of PROJECT include Project ID (identifier), Project Name, and Start Date. Each employee may be assigned to one or more projects or may not be assigned to a project. A project must have at least one employee assigned and may have any number of employees assigned.
