-x+3=4 plz solve and Explain
Answer:
x=-1
Step-by-step explanation:
-x+3=4
-3 -3
-x=1
multiply by negative one to get rid of negative in front of x
x=-1
Answer:
here we have to bring the +4 into first part then -x in second part then it will be 3-4=x
then solve now -1=x
If x and y are positive integers is x - y always positive explain
Note that x and y are nonzero integers. It means that x and y will always have same sign (both are either positive or negative, since they are nonzero). Hence, xy term is always positive.
Answer:
No, if y happens to be a larger integer than x, then the result will be negative.
Step-by-step explanation:
For example, lets say that x=4 and y=9, so x-y = 4-9 = -5.
But if we were to reverse it and make x=9 and y=4, then x-y = 9-4 = 5.
write a function G whose graph represents the indicated transformation of the graph f
[tex]f(x) = \frac{2}{3} {x}^{2} + 2[/tex]
vertical stretch by a factor of 3
Answer:
[tex]G(x) = 2x^2+6[/tex].
Step-by-step explanation:
The given function is
[tex]f(x) = \frac 2 3 x^2 +2[/tex]
On vertical stretch by a factor of 3, the new function G(x) is
G(x) = 3 f(x)
So, [tex]G(x) = 3 \times ( \frac 2 3 x^2 +2)= 2x^2+6[/tex]
Hence, the required function is [tex]G(x) = 2x^2+6[/tex].

Gracie is sharing 75 marshminnows among 4 of her friends. If each of her friends gets the same number of marshminnows, and she gives them as many marshminnows as
possible, how many are left for Gracie?
none
3
18
19
Answer:
18
Step-by-step explanation:
If you want to give people something, you need to divide the number that she is sharing (75) and the number of how many people she is sharing with (4).
So 75/4 = 18
So 18 marshminnows are left for Gracie.
Suppose that a new employee starts working at $7.72 per hour and receives a 4% raise each year. After time t, in years, his hourly wage is given by the equation y=$7.72(1.04)t. Find the amount of time after which he will be earning $10.00 per hour.
Answer:
6.5978 years
Step-by-step explanation:
y=7.72(1.04)^t
10=7.72(1.04)^t
1.04^t=1.2953367875647668
log 1.04^t=log 1.2953367875647668
t log 1.04=log 1.2953367875647668
t=6.5978 years .............

Answer:
[tex]T_n=(4-n)\text{log}_a(3)+\text{log}_a(2)[/tex]
Step-by-step explanation:
nth term of an A.P. is given by the explicit formula,
[tex]T_n=a+(n-1)d[/tex]
Here, 'a' = First term
n = number of term
d = common difference
For an A.P. given as,
[tex]\text{log}_a(54),\text{log}_a(18),\text{log}_a(6),....[/tex]
First term 'a' of the given A.P. = [tex]\text{log}_a(54),[/tex]
Common difference 'd' = [tex]T_2-T_1[/tex]
= [tex]\text{log}_a(18)-\text{log}_a(54)[/tex]
= [tex]\text{log}_a(\frac{18}{54})[/tex]
= [tex]\text{log}_a(\frac{1}{3})[/tex]
= [tex]-\text{log}_a(3)[/tex]
[tex]T_n=\text{log}_a(54)+(n-1)[-\text{log}_a(3)][/tex]
[tex]=\text{log}_a(54)-(n-1)\text{log}_a(3)[/tex]
[tex]=\text{log}_a(3^3\times 2)-(n-1)\text{log}_a(3)[/tex]
[tex]=\text{log}_a(3^3)+\text{log}_a(2)-(n-1)\text{log}_a(3)[/tex]
[tex]=3\text{log}_a(3)+\text{log}_a(2)-(n-1)\text{log}_a(3)[/tex]
[tex]=3\text{log}_a(3)+\text{log}_a(2)-n\text{log}_a(3)+\text{log}_a(3)[/tex]

Step-by-step explanation:
what is the area of a shaded region in the quarter circle
radius 12
Answer:
I guess that the shaded area is a quarter of a circle of radius 12 units.
Is easy to know that the area, will be equal to the quotient between the area of a circle of radius 12, and 4
We know that the area of a circle of radius R is:
A = pi*R^2
in this case, R = 12
pi = 3.14
Then:
A = 3.14*12^2 = 452.16
And a fourth of that is:
A/4 = (452.16)/4 = 113.04
The area of the shaded region is 113.04 square units
the mean of a,b,c,and d is 9 and the mean of a,b,c,d,e and f is 12. find the mean of e and f
Answer:
mean of e + f = 18
Step-by-step explanation:
(a + b + c + d)/4 = 9 Multiply by 4
a + b + c + d = 9 * 4 = 36
(a + b + c + d + e + f ) / 6 = 12
but a + b + c + d = 36
(36 + e + f)/6 = 12 Multiply by 6
36 + e + f = 72 Subtract 36 from both sides
e + f = 36 Divide by 2 to find the mean.
(e + f)/2 = 36/2
mean of e + f = 18
Which statement describes the graph of function g?
f(x) = 2x
g(x) = 2x + 3
The graph of g is 3 units to the left of the graph of f.
The graph of g is 3 units below the graph of f.
The graph of g is 3 units above the graph of f.
The graph of g is 3 units to the right of the graph of f.
9514 1404 393
Answer:
The graph of g is 3 units above the graph of f.
Step-by-step explanation:
Adding 3 to each y-value shifts the graph up 3 units.
__
In the case of the straight line given here, it also has the appearance of shifting the graph left. The left-shift, however, is not 3 units. The amount of apparent horizontal shift will depend on the slope of the original line.

Im confusion? Could someone help me out.
Answer:
20cm
Step-by-step explanation:
for the triangle:
Perimeter = 30cm
a + a + a = 30
3a = 30
hence a = 10cm
For the rectangle:
Perimeter = 30cm
a + a + b + b = 30
but a = 10cm
10 + 10 + b + b = 30
20 + 2b = 30
2b = 10
hence b = 5cm
Perimeter of square = b + b + b + b
= 5 + 5 + 5 + 5 = 20cm

Let us pick -5 and -4 which are one unit apart.We will find the difference by finding the slope: -3-(-11)/-4-(-5)= 8 Next for 2 units apart we will choose 1 and 3We do the same thing: 53-37/3-1= 16/2=8 Next we will pick something 2 units apart. Let's pick 0 and 3 Hence we will do the same: 53-29/3-0= 24/3=8No matter what difference we pick, whether that be one, two or three units, the difference is the same and consistent.Rate brainlist and drop a followWhat is the value of u? 6.4u−5.1u=−3.25

• b² = 5×5
= 25
• a² + b² = c²
= 144 + 25 = 169
• c = _/169

The equation modeling the population growth of a small town is P(t)=30000(1.02)^t, where P represents the population, and t represents the years from now. What is the approximate population change that occurs between 2 years from now and 10 years from now.
Answer:
5358
Step-by-step explanation:
The equation modeling the population growth of a small town is given as:
P(t)=30000(1.02)^t
When t = 2
P(2) = 30000(1.02)^2
P(2) = 31212
When t = 10
P(10) = 30000(1.02)^10
P(10) = 36569.8326
The approximate population change that occurs between 2 years from now and 10 years from now is calculated as:
= P(10) - P(2)
= 36569.83259984272 − 31212
= 5357.8325998
Approximately ≈ 5358

Step-by-step explanation:
y = 250 (1+0.2)
First add the 1 and 0.2
y=250(1.2)
multiply 250 with 1.2
y = 300

At the moment there are 54,210 tagged birds in a certain wildlife refuge. If exactly 20 percent of all birds in the refuge are tagged, what percent of the untagged birds must be tagged so that half of all birds in the refuge are tagged?
Answer:
37.5%
Step-by-step explanation:
OOF DIS COMPLICATED
I messed up big timeeeeeeeee
A lot of percent problem are very simple by just assuming values, especially in case the answer is also a percentage.
If there are 100 birds, 20% are tagged so 20 are tagged.
Out of the rest 80, 30 should be tagged so that a total of 50% are tagged.
30/80 = 37.5%
(The huge number given is unnecessary, just to make you waste your valuable time. Read the question again to realize that it is not needed.)
The percent of the untagged birds that must be tagged so that half of all birds in the refuge are tagged is 37.5%.
Untagged birds percentage:First step
Currently Tagged birds= 54210 ×20/100
Currently Tagged birds=10842
Second step
Untagged birds=54210 - 10842
Untagged birds=43368
Third step
Untagged birds percentage:
Untagged birds percentage=( 54210/2)-10842/43368
Untagged birds percentage=(27105-10842)/43368
Untagged birds percentage=16263/43368
Untagged birds percentage=0.375×100
Untagged birds percentage=37.5%
Inconclusion the percent of the untagged birds that must be tagged so that half of all birds in the refuge are tagged is 37.5%.

The sum of three consecutive numbers is 72 what is the smallest of the numbers
Answer:
23
Step-by-step explanation:
Suppose,
the first number = x
the second number = x+1
the third number = x+1+1 = x+2
Question wise,
x+x+1+x+2 = 72
3x+3 = 72
3x = 72-3 = 69
x = 69/3 = 23
so the numbers are,
23,(23+1)=24 and (23+2)=25
