What is the equation of the line that includes the points (1,6) and (2,8)?
Answer: y = 2x + 4
Step-by-step explanation:
y = mx + b
(1,6) and (2,8)
Finding Slope:
(8 - 6) / (2 - 1)
=> 2/ 1 or 2
y = 2x + b
Finding "B":
y = 2x + b
=> 6 = 2(1) + b
=> 6 = 2 + b
=> b = 4
so y = 2x + 4
5 x 143 = 5 x ( + + ) write 143 in expanded form.
Answer:
Step-by-step explanation:
143 = 100 + 4 0 + 3
5*(143) = 5 * (100 + 40 + 3)
= 5*100 + 5*40 +5*3
= 500 + 200 + 15
= 715
How can you use similar triangles to solve problems?
Answer:
you can use similar triangle to make known degrees in problems to make then easier to solve. With similar triangle, the angles are the same, but the scale is different. So by using this, one can solve both at the same time, and just just scale up the smaller one or scale down the larger, by the given/found scale.
Step-by-step explanation:
Answer:
You can indirectly determine the measure or size of something that is tedious to measure by hand.
Or by knowing that the triangles are similar, you can find the corresponding sides, angles or even other variables based on the information that is given.
If a triangle is similar to another, they are proportional; usually have congruent angles, which means that the only differing variable is the scale factor, or relative position.
What is the product of (3x + 1)(3x – 4)?
Step by step.
Answer:
9x^2-9x-3
Step-by-step explanation:
3x*3x=9x^2
3x*-4=-12x
1*3x=3x
1*-4=-3
9x^2-12x+3x-3
9x^2-9x-3
Answer:
9x^2 - 9x - 4
Step-by-step explanation:
(3x + 1)(3x – 4)
Here you can use the FOIL method (FOIL stands for: First, Outer, Inner and Last)
First you multiply 3x by 3x since these are the First inside both binomials.
3x * 3x = 9x^2
Then you multiply 3x by -4 since these are the Outer inside both binomials.
3x * -4 = -12x
Then you multiply 1 by 3x since these are the Inner inside both binomials.
1 * 3x = 3x
Then you multiply 1 by -4 since these are the Outer inside both binomials.
1 * -4 = -4
And finally add everything together:
9x^2 + (-12x) + 3x + (-4)
Since adding a negative number is the same as subtracting it:
9x^2 - 12x + 3x - 4
We can now simplify this a little by adding all the x's together:
9x^2 - (12x + 3x) - 4 =
9x^2 - 9x - 4

Step-by-step explanation:
A middle school football player, Bo, is just learning how to kick field goals. Currently, he only makes 1/3 of his kicks. A die is being used to simulate the result of Bo's kicks where the numbers 1 or 2 represent a made field goal the numbers 3, 4, 5, or 6 represent a missed field goal. Use the following 20 trials of rolling a fair die to answer the question.
Based on the outcomes given, what is the estimate of the probability that Bo does not make any field goals? Write your answer as a fraction
Answer:
The correct answer is 75%.
Step-by-step explanation:
If you count all the misses in each trial as one whole miss, then you will have 15 total misses which would then leave to 5 makes. Then you divided 15 by 20 which would give you a perfect 75% of him missing the field goal. So basically, your answer is 75%.

Write an equation in point-slope form of the line that passes through the point (5, 6) with slope 3/5
Answer:
(y - 6) = 3/5(x - 5)
Step-by-step explanation:
First, let's look at what point-slope form is: (y - y₁) = m(x - x₁)
Let's plug in the vallues we know.
m is the slope: 3/5
x₁ is 5
y₁ is 6
Therefore:
(y - 6) = 3/5(x - 5)
This is your equation.

Write a linear equation that represents the area and a linear equation that represents the perimeter of the rectangle.
(3x-3) cm and
6 cm
I need a linear equation for for area and a linear equation for perimeter.
Answer:
Assuming that (3x - 3) and 6 are the sides of the rectangle,
Area:
A = l × w
y = (3x - 3) × (6)
y = 18x - 18
Perimeter:
P = 2l + 2w
y = 2(3x - 3) + 2(6)
y = 6x - 6 + 12
y = 6x + 6
The required linear equation for the area and perimeter of the rectangle is y = 18[x - 1] and z = 6[x + 1] respectively.
Given that, to determine the linear equation that represents the area and a linear equation that represents the perimeter of the rectangle.
The rectangle is 4 sided geometric shape whose opposites are equal in length and all angles are about 90°.
here,
Length = 3x + 3
Width = 6
Area of the rectangle = y, = length × width
y = [3x - 3 ] × [6]
y = 18x - 18 = 18[x -1]
Perimeter of the rectangle = 2[length + width]
z = 2 [3x - 3 + 6]
z = 2 [3x + 3]
z = 6[x + 1]
Thus, the required linear equation for the area and perimeter of the rectangle is y = 18[x - 1] and z = 6[x + 1] respectively.

Solve log x = 3
a. x=3
b. x=30
c. x=1,000
d.x=10,000
Answer:
c. x=1,000
Step-by-step explanation:
log x = 3
Imagine that it's log10 x = 3
So, x = 10^3 (10 to the third power)
x = 10 * 10 * 10
x = 1,000
In a store, 7/200 of the shirts are yellow and 69/600 are pink . What percent of the shirts are not yellow or pink.?
Answer:
510/600 of the shirts are not yellow or pink.
Step-by-step explanation:
First we turn 7/200 with a denominator of 600.
7/200 = 21/600
Next we add 69/600 with 21/600.
69/600 + 21/600 = 90/600
Now we subtract 600 by 90.
600 - 90 = 510.
So, the answer is 510/600

round 0.009 to the nearest hundredth
Answer:
0.01
Step-by-step explanation:
Rounded to the nearest hundredth 0.009 is 0.01.
The term "Rounding off" means the process of approximating a number to a specified degree of accuracy by replacing it with a neighboring value that is efficient to work with, and makes calculation easy or more meaningful in a given context. This involves reducing the number of significant digits or decimal places in a numerical value while retaining its overall magnitude.
To round off 0.009 to the nearest hundredth, 1 is added to the digit in second place after the decimal, i.e., 0, and the digit in the third place after the decimal, i,e, 9 is replaced by 0.
Thus, when rounded to the nearest 100th, 0.009 results as 0.01.

If I have 50 envelopes I put equal amounts of money in each one how much will I have at the end of 50 days
Answer:
At the end of 50 days , Amount of money = $2500x
where x is the value that added every day.
Step-by-step explanation:
Let daily amount added in 1 envelope = $x
As, we have 50 envelope,
so, daily added amount in 50 envelope = $ 50x
⇒ Each day , we add money = $ 50 x
After 50 day, it becomes $50×50x = $2500x
For example -
If we add $ 1 every day in each envelope
then ,
Total amount added in 50 envelope each day = $50×1 = $ 50
Then,
After 50 days,
Total amount = $ 50×50 = $2500
∴ we get
At the end of 50 day, total amount we have = $2500

4. 5.75%
5. $15,785
6. $20,960
Step-by-step explanation:
I (interest) = p(principal, or money deposited) x r (rate, converted from percentage to decimal) x t (time, in years)
Plugging in info for #4:
241.50 = (1,050) (r) (4)
241.50 = 4200r
divide both sides by 4200
r = 0.0575
multiply by 100 to change from decimal to percentage, = 5.75% is the rate
Plugging in for #5:
(remember to divide percentage by 100 to go from percent to decimal)
I = (410,000)(0.0385)(1)
Interest = $15,785
Number 6 takes two steps. One is the equation we've been doing, the other is to add that interest to the amount deposited in the first place.
I = (8,000)(0.09)(18)
Interest = $12,960
Now add the $12,960 to the $8,000 deposit in the first place, and you have $20,960
If f(x) = x^3 + 8x² + 11x-20 and x+5 is a factor of f(x), then find all of the zeros of f(x) algebraically
Answer:
The zeros are (-5,-4,-1)
Step-by-step explanation:
Since we have a linear factor, we can use the method of long division to get the other factors
What this mean is that we simply divide the polynomial by the linear expression
we have this division result as;
By dividing, we have the other factor as ;
x^2 + 3x - 4
so we simply factorize this
x^2 -x + 4x - 4
x(x-1) + 4(x-1)
(x + 4)(x-1)
So the complete factors are;
(x + 5)(x + 4)(x-1)
To get the zeros, we simply equate each of the terms to zero
and we have our answer as;
-5 , -4 , 1
90% of what equals 81?? Please show how you got the answer!!
Answer:
90Step-by-step explanation:
First you want to divide 81 by 90%. You do this because 81 is the number you have and 90 is the percent you have.
81/90% = 90
Doing this will get you 90. This works for all percentages too.
Also you can check your answer by reversing this.
90 × 90% = 81
Calcule o saldo de salário, o funcionário foi admitido em 10 de janeiro como mensalista, salário R$ 1400,00?
Responda:
$ 980
Explicação passo a passo:
Dado que:
Salário mensal = $ 1400
Data de emprego = 10 de janeiro
Usando o sistema de mês de 30 dias:
Taxa diária =. $ 1400/30 = $ 46.66666
Dias não trabalhados = janeiro - 9 de janeiro = 9 dias
Subtraia o salário de 9 dias do total:
Salário total - (9 * taxa diária)
$ 1400 - (9 * $ 46,66666)
$ 1400 - $ 420
= $ 980
Portanto, o saldo do salário é de $ 980
