Step-by-step explanation:
Use the FOIL method
w × 6w =
[tex]6 {w}^{2} [/tex]
w × 2z = 2wz
-7z × 6w = -42wz
-7z × 2z =
[tex] - 14 {z}^{2} [/tex]
this simplified equals
[tex]6 {w}^{2} - 40wz - 14 {z}^{2} [/tex]
first term: 6w^2
second term: -40wz
third term: -14z^2
-25-2x=3x
I know the answer to the problem but i´m not sure how to move the constant (-25) to the other side. When you move the constant to the right side the equation should be -2x=3x+25. How do you move a constant to the other side?
In this case I believe you would add 25 to both sides. The -25 +25 would cancel out and then +25 would be on the right.

At the toy store, 4 toy cars cost $3.84. How much does it cost to buy 20 toy cars?
A. $20.20
B. $17.20
C. $19.20
D. $21.20
Whoever gets the correct answer will get a crown!!!
Step-by-step explanation:
To answer this, we need to find the scale factor which is to find how much one individual car is worth.
So we need to divide 3.84 and 4.
3.84 ÷ 4 = 0.96
So each car is $0.96.
To find 20 toy cars, we need to multiply 0.96 and 20.
The answer is:
$19.20

Answer:
11 73/78 ≈ 11.9359 (not 14)
Step-by-step explanation:
The similarity statement tells us ...
QS/QR = FG/FH
QS = QR·FG/FH
13x -14 = 154(55/60) = 847/6
Adding 14 = 84/6, we have ...
13x = 931/6
x = 931/78 = 11 73/78 . . . . . . . divide by 13
__
Comment on the question
You get a nice integer answer for x if the similarity statement is written ...
∆FGH ~ ∆QRS . . . . . . . note the letters are in alphabetical order
Then you have ...
QS/QR = FH/FG
13x -14 = 154(60/55) = 168
13x = 182
x = 14
This nice answer to a nice similarity statement leads us to believe the question has an error in it.
We suspect you are expected to provide x=14 as the answer, even though that is NOT the answer to the question as written. You may want to discuss this with your teacher.

Find the equation of the straight line with the
slope m= 1/2 and the y intercept is -1
Answer:
y = [tex]\frac{1}{2}[/tex] x - 1
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = [tex]\frac{1}{2}[/tex] and c = - 1 , then
y = [tex]\frac{1}{2}[/tex] x - 1 ← equation of line

Answer:
30° and 150°
Step-by-step explanation:
Supplementary angles sum to 180°
sum the parts of the ratio, 1 + 5 = 6 parts
Divide 180° by 6 to find the value of 1 part of the ratio
180° ÷ 6 = 30° ← value of 1 part of the ratio , then
5 parts = 5 × 30° = 150°
smaller angle = 30°
larger angle = 150°

Scientists measure a bacteria population and find that it has 10,000 organisms. Five days later, they find that the population has doubled. Which function f could describe the bacteria population d days after scientists first measured it, assuming it grows exponentially?
Answer:
f(x)= 10,000(2)^x
Step-by-step explanation:
Exponential equations can be modeled by a(r)^x where a is the initial amount, r is the difference, and x is how many units the equation should be squared by.
A function that describes the bacteria population after d days would be,[tex]\bold{f(d) = 10000\times(1+0.15)^d}[/tex]
What is an exponential growth?An exponential growth function is a function that grows at a constant percent growth rate.
What is an exponential growth function?f(t) = a×(1 + r)^(t)
where f(t) = exponential growth function
a = initial amount
r = growth rate
t = number of time intervals
For given example,
initially a bacteria population (a) = 10,000
Five days later, they find that the population has doubled.
d = 5, f(5) = 20,000
Assuming it grows exponentially, we find the growth rate of a bacteria population by using the formula of exponential growth function.
[tex]\Rightarrow f(d) = a\times(1 + r)^{d}\\\\\Rightarrow f(5) = 10000\times (1+r)^5\\\\\Rightarrow 20000=10000\times (1+r)^5\\\\\Rightarrow 2=(1+5)^5\\\\\Rightarrow 1+r=\sqrt[5]{2}\\\\\Rightarrow 1+r = 1.15\\\\\Rightarrow r = 1.15-1\\\\\Rightarrow \bold{r = 0.15}\\\\\Rightarrow \bold{r=15\%}[/tex]
This means, the exponential growth function would be,
[tex]\bold{f(d) = 10000\times(1+0.15)^d}[/tex], where d represents number of days.
