Answer:
A = 92y + 81
Step-by-step explanation:
Because A = number of attendees and if it adds 92 each year, you times the number of years by 92 and add 81 for the ones that were already there
1/2a - 6 = 3 + a solve for a plssss

1. (2, -3) → (-3, 2) reflection across both axes
2. (2, -3) → (2, 3) reflection across the x-axis
3. (2, -3) → (-2, -3) not a reflection
4. (2, -3) → (-2, 3) reflection across the y-axis
Answer:
(2, -3) → (2, 3) reflection across the x-axis
(2, -3) → (-2, -3) reflection across the y-axis
(2, -3) → (-2, 3) reflection across both axes
(2, -3) → (-3, 2) not a reflection
Step-by-step explanation:
Reflection across the x-axis:
When we reflect a point across the x-axis, it's x coordinate keeps the same value, while the signal of the y-coordinate is changed, having the same value, with different signal.
So the correct option is:
(2, -3) → (2, 3) reflection across the x-axis
Reflection across the y-axis:
When we reflect a point across the y-axis, it's y coordinate keeps the same value, while the signal of the x-coordinate is changed, having the same value, with different signal.
So the correct option is:
(2, -3) → (-2, -3) reflection across the y-axis
Reflection across both axis:
Both change the signal. So
(2, -3) → (-2, 3) reflection across both axes
Rotations:
When we have a rotation, not only the signals can change, but also the numbers, x with y and y with x. Rotations are not reflections. So
(2, -3) → (-3, 2) not a reflection

3/4 х36 how do I solve it
Hi there!
Convert 36 into 35 and 4/4 since if it is just a number, it can’t be multiply by 3/4.
[tex]36= 35 \frac{4}{4}[/tex]
Multiply both fractions now but also turn 35 4/4 into a mixed number:
[tex]36=\frac{144}{4}[/tex]
[tex]\frac{3}{4} x \frac{144}{4}= \frac{27}{1} = 27[/tex]
Final Result: 27

What are the wavelengths for X-rays with frequency 3 x 10187
O 1x 10-10 m
O 3 * 10-10 m
O 3 * 1026 m
O 9 1026 m
Answer:
[tex]\lambda=10^{-10}\ m[/tex]
Step-by-step explanation:
Given that,
The frequency of x-rays, [tex]f=3\times 10^{18}\ Hz[/tex]
We need to find the wavelength for x-rays. The relation between wavelength, frequency and speed of light is given by :
[tex]v=f\lambda\\\\\lambda=\dfrac{c}{f}\\\\\lambda=\dfrac{3\times 10^{8}}{3\times 10^{18}}\\\\=10^{-10}\ m[/tex]
So, the wavelength for x-rays is [tex]10^{-10}\ m[/tex].
Answer:
1x 10-10 m

Which expression are equivalent to 3p + 15? choose ALL THAT APPLY
A) 3(p + 5)
B) 2p - p + 15
C) 7p - 4p + 15
D) 3(p + 15)
Answer:
A and C
Step-by-step explanation:
The equivalent expressions are:
3(p + 5) and 7p - 4p + 15
Options A and C are the correct answer.
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
3p + 15
Taking out common factors.
3 (p + 5) ____(1)
And,
7p - 4p + 15
3p + 15
3(p + 5) _____(2)
From (1) and (2),
3(p + 5) and 7p - 4p + 15 are equivalent expression.
Thus,
The equivalent expressions are:
3(p + 5) and 7p - 4p + 15

7/8 - 1/12 its a math question
Answer:
19/24 = 0.791666667
Step-by-step explanation:
7/8 - 1/12
Least common multiple of 8 and 12 is 24. Convert 7/8 and 1/12 to fractions with denominator 24.
21/24 - 2/24
Since 21/24 and 2/24 have the same denominator, subtract them by subtracting their numerators.
21 - 2 / 24
Subtract 2 from 21 to get 19.

Answer:
3/8
Step-by-step explanation:
First convert 1/2 into eights. 1/2 as eighths is 4/8.
So 4/8-1/8=3/8.
Therefor, 3/8 is the answer you're looking for.
I hope I helped :)
Answer:
3/8
Step-by-step explanation:
you have to find the LCM (least common multiplier) of 2,and 8 and that would be 8 therefore youd change the fractions from 1/2-1/8 to 4/8-1/8 you subtract the tops and keep the bottoms the same as 8. so 4-1=3 therefore the anwser would be 3/8

the sum of two consecutive even integers is 138
Answer:
68 and 70
Step-by-step explanation:
if the first integer is x, the next would be x + 2
so your equation is x + x+2 = 138
2x + 2 = 138
minus 2 on both sides
2x =136
x = 68
so if x is 68
x + 2 would be 70
if you add those up, im pretty sure you'll get 138

What are the y-intercept and axis of symmetry of this quadratic function? 5 Select two answers: one for the y-intercept and one for the axis of symmetry
Answer:
y intercept: (0,1)
Axis of symmetry: x=-2
Step-by-step explanation:
The y intercept is where the curve crosses the y axis.
y intercept: (0,1)
The axis of symmetry is the x value where drawing a vertical line has the left side of the curve a mirror image of the right side of the curve.
Axis of symmetry: x=-2
The required y-intercept is (0, 1) and the axis of symmetry is x = -2. Options A and C are correct.
What is the intercept in the equation?In the equation intercept is the value of the linear function where either of the variables is zero.
Here,
From the above definition in the graph locate the value of y when x is zero,
So, in the graph, when x is zero y is 1
There is why the y-intercept of the given function is 1,
Now,
For the axis of symmetry, just draw a line with a vertex that part the function in two equal halves,
So vertex of the given function is (-2, -3), and the line that divides the function in two equal halves is x = -2
Thus, Options A and C are correct.

What is the value of a?
Answer:
a=22
Step-by-step explanation:
2a+2=46
2a=46-2
2a=44
a=44÷2
a=22
Answer:
a = 22°
Step-by-step explanation:
Since vertical angles are always congruent we know that 46° = 2a + 2°, therefor...
46° = 2a + 2°
2a = 46° - 2°
2a = 44°
a = 44° / 2
a = 22°

Step-by-step explanation:
The complete table:
Days 1 2 3 4 5

The equation for the number of bacteria analyzes after x days.
B = 15x
Now,
x = 1, B = 15
x = 2, B = 30
x = 3, B = 45
x = 4, B = 60
