Winston needs at least 80 signatures from students in his school before he can run for class president. He has 23 signatures already. He and two of his friends plan to get the remaining signatures during lunch. If each person gets the same number of signatures, which inequality can Winston use to determine the minimum number of signatures each person should get so he can run for class president?Solve the inequality algebraically.
Answers
Answer:
At least 19 signatures.
Step-by-step explanation:
Winston already has 23 signatures, so he has 57 left to go (80 - 23).
There are 3 people collecting signatures, so the equation will be as following:
3x ≥ 57
To break down this equation, 3x because each person is collecting x number of signatures, and 57, because if you add those signatures upp, then it will have to be at least 57, therefore the operator should be ≥ .
If you solve 3x ≤ 57, then you will find that x ≥ 19, so they each have to have at least 19 signatures.

Which inequality contains (0,0)
Answers
Answer:
D
Step-by-step explanation:
D
Explanation: If it helps, plug both the x and y values in each inequality. For the first, 0 is greater than -5, so A is not the answer. For the second, 0 is less than 3, so B is not the answer. For the last, there is no equal sign, so D is not the answer. (In order to make the inequality true, it has to be a greater than or equal to sign.) Now, for the third, 0 IS greater than -4, making that inequality true.

En tu trabajo de ciencias te toco realizar un experimento de cultivó de hongos en una pieza de pan de harina de trigo y una tortilla de maiz. La secuencia de revisión para la toma de datos será, en el primer caso, cada 15 dias; y en el otro, cada 20 por tres meses. ¿A los cuantos días te tocaría revisar ambos cultivos?
Answers
Responder:
60 días
Explicación paso a paso:
Primer caso = cada 15 días
Segundo caso = cada 20 días
El número de días en los que habrá que comprobar ambos cultivos se puede obtener encontrando el mínimo común múltiplo de 15 y 20
Múltiplo de:
15:15, 30, 45, 60, 75, 90, 105
20:20, 40, 60, 80, 100, 120
El mínimo común múltiplo de 20 y 15 es 60
El día en el que habrá que controlar ambos cultivos es de 60 días

If the point (0, 20) is the y-intercept of the parabola with the vertex is (8, -12), What is the equation for this parabola.
Answers
Answer:
f(x) = ¹/₂(x - 8)² - 12Step-by-step explanation:
f(x) = a(x - h)² + k - vertex form of the equation of the parabola with vertex (h, k)
so the equation of parabola with the vertex (8, -12) is
f(x) = a(x - 8)² - 12
The point (0, 20) is the y-intercept means if x=0 then f(x)=20
20 = a(0 - 8)² - 12
20 +12 = 64a - 12 +12
32 = 64a
a = ³²/₆₄ = ¹/₂
Therefore the equation (in vertex form) of parabla is:
f(x) = ¹/₂(x - 8)² - 12

The college student who is looking for a data plan for her cell phone found a third option,
which also offers a 2 gigabyte monthly allowance for data.
The monthly cost of this option can be represented by function C defined by:
C(x) = 30x + 5, where x is the gigabytes of data used over the monthly allowance.
1. Find C(0.7) and explain what it means in this situation,
Answers
Answer:
C(0.7) = 26
Step-by-step explanation:
Given:
C(x) = 30x + 5
where,
x = gigabytes of data used over the monthly allowance.
1. Find C(0.7) and explain what it means in this situation
C(0.7) means he used 0.7 gigabytes of data over the monthly allowance
Substitute x = 0.7 into the equation to find the monthly cost of the option
C(x) = 30x + 5
C(0.7) = 30(0.7) + 5
= 21 + 5
= 26
C(0.7) = 26
When x = 0.7, his total cost will be 26

X-3y=9 into a slope intercept form
Answers
Answer:
y=1/3x-3
Step-by-step explanation:
Slope intercept form is: y=mx+b
so you need to leave y on one side and the others on the other side:
First, you need to move the x to the other side by subtracting x on both sides:
x-x-3y=-x+9
Simplify:
-3y=-x+9
Now you divide -3 on both sides to eliminate the -3 on -3y:
y=1/3x-3
Hope this helps!
- Slope is m which is the gradient.
- the gradient formula is y=mx+b
-I.e mx represent the gradient and b is y-intercept.
- x-3y=9–> 3y=x-9
Then divide 3 to both side to cancel the 3y=y.
—> y=x/3-3

Step-by-step explanation:
The angles 76° , 34°, and c make up a triangle. A triangle has a sum of 180°.
180° = 76° + 34° +c
c=70°
The parallel lines create 2 congruent triangles so we can use the same angles from the first triangle for the second one.

b. 48 girls
c. 15 more girls than boys
Step-by-step explanation:
a. if the ratio for the question is 2:3 with a refernce ratio of 24:X, with cross multiplication we find out the x=36
b. now we must separate 80 into the 2:3 ratio making 32:48 with 48 girls
c. the same thing will be done with 75, making its 2:3 ratio 30:45, to find the difference of the two numbers you must subtract, this shows that the difference is 15 more girls.

f(x) = 5x^3 + 2x^2 – 7x + 4
g(x) = 3x – 7
Find (f +g)(x)
Answers
Answer:
d
Step-by-step explanation:
I am pretty sure that is the answer
A function assigns the values. The value of (f +g)(x) for the two given functions f(x)=5x³+2x²–7x+4 and g(x)=3x–7 is 5x³ + 2x² – 4x – 3. The correct option is D.
What is a Function?A function assigns the value of each element of one set to the other specific element of another set.
Given the two functions such as,
f(x) = 5x³ + 2x² – 7x + 4
g(x) = 3x – 7
Now, the value of (f +g)(x) is the value of the function which is produced when the two of the given function are added together, therefore, the value of the added function can be written as,
(f +g)(x) = f(x) + g(x)
(f +g)(x) = (5x³ + 2x² – 7x + 4) + (3x – 7)
= 5x³ + 2x² – 7x + 4 + 3x – 7
= 5x³ + 2x² – 4x – 3
Hence, the value of (f +g)(x) for the two given functions f(x)=5x³+2x²–7x+4 and g(x)=3x–7 is 5x³ + 2x² – 4x – 3.
