Question 7 which graph represents a function
Answer:
Where are the graphs?
Step-by-step explanation:
Anyway use this method.
Use the vertical line test to determine whether or not a graph represents a function. If a vertical line is moved across the graph and, at any time, touches the graph at only one point, then the graph is a function. If the vertical line touches the graph at more than one point, then the graph is not a function.
Write and solve an equation to answer the question. 14 is what percent of 70?
Answer:
20%
Step-by-step explanation:
An equation is 14=x/100*70 or 14=(x%)*70, either one works
solve for x:
14=x/100*7014/70=x/100 (Divide each side by 70)1/5=x/100 (Simplify 14/70)100/5=x (Multiply each side by 100 to isolate x)x=20 (Simplify 100/5)20% (Rewrite as a percent)hope this helps!!

Solve : 2 (m + 1) = 3(m - 1)
Step-by-step explanation:
hope this helps. if you have any questions don't hesitate to ask :))
Answer:
m = 5
Step-by-step explanation:
Given
2(m + 1) = 3(m - 1) ← distribute parenthesis on both sides
2m + 2 = 3m - 3 ( subtract 2m from both sides )
2 = m - 3 ( add 3 to both sides )
5 = m

** please help its due soon **
Answer:
x = {-4, -2}Step-by-step explanation:
To find the intersection we need to solve the system:
y = 2x + 3(x - 3)² + (y + 6)² = 50Solve by substitution, replace y with 2x + 3 in the second equation:
(x - 3)² + (2x + 3 + 6)² = 50x² - 6x + 9 + 4x² + 36x + 81 - 50 = 05x² + 30x + 40 = 0x² + 6x + 8 = 0x² + 6x + 9 = 1(x + 3)² = 1x + 3 = ± 1x = -4, x = -2WILL GIVE BRAINLIEST TO THE BEST ANSWER

Determina la EPG que adquiere una trapesista de 52 kg de masa cuando sube a un trapecio de 8 metros de altura. Considera g=9.81
Responder:
4080,96 Julios
Explicación paso a paso:
La energía potencial gravitacional adquirida se puede obtener mediante la relación:
EPG = masa * aceleración por gravedad * altura
Masa = 52 kgb; aceleración debida a la gravedad = 9,81; h = 8 metros
EPG = 52 * 9,81 * 8
EPG = 4080,96 julios

Answer:
I believe it might be C. -3
Answer:
The answer is C. -3
Step-by-step explanation:
You could go about solving this mathematically or graphically. I'll explain both ways.
Mathematically: Plug the points into this equation
y(2) - y(1) / x(2) - x(1)
If you do this, it will be -2- 4 / 1 - -1, which equals -6/2. You can simplify this to -3 and there you go.
Graphically: Start on the point (-1,4) and count on the graph until you get to (1,-2) That will be down six units and right two units. This can be written as -6/2, which of course, can be simplified to -3.

Tom made fruit punch for a party. He mixed 2 gallons of orange juice, 4 quats of pinnapple juice, 3 pints of cranberry juice. How many quarts did he make in all?
Answer:
13.5
Step-by-step explanation:
Tom made fruit punch for a party
He used the following amount of fruits
2 gallons of orange juice
= if 1 gallon is 4 quart then 2 gallon is 4×2= 8 quarts
3 pints of cranberry juice
= if 1 pint is 0.5 quart then 3 pints is 0.5×3 = 1.5 quarts
The amount of quartz he made can be calculated as follows
= 1.5 + 8 + 4
= 13.5
Hence he made 13.5 quarts of fruit punch

Answer:
Angle ADC = 80 degrees
Step-by-step explanation:
Here, we want to find the measure of angle ADC
mathematically, sum of angles at a point is 360
Thus;
x + 3x + x + 10 = 360
5x + 10 = 360
5x = 360-10
5x = 350
x = 350/5
x = 70
From the diagram;
angle ADC is (x + 10)
so we have; (70 + 10) = 80 degrees

Triangle congruence and similarly (picture included) SAS, ASA, SSS, or AAS?
Answer:
SAS
Step-by-step explanation:
SAS Postulate: "If two sets of corresponding sides on two triangles and there included angle are congruent, then the triangles are similar".
We see that line segments XY-ST and XZ-SR are congruent along with the included angles X and S. Therefore, we can justify that SAS fits the situation.

En una granja se crían gallinas y cerdos. Entre las dos clases de animales hay 40 cabezas y 110 patas. ¿Cuántos animales hay de cada clase?
Answer:
Total pigs in the farm = 15
Total chickens in the farm = 25
Step-by-step explanation:
Given - Chickens and pigs are raised on a farm. Between the two classes
of animals there are 40 heads and 110 legs.
To find - How many animals are there of each class?
Proof -
Given that , there are two types of animals - Chicken and pigs.
Let Chicken is represented by c
Pigs are represented by p
Given , there are 40 heads and 110 legs.
As we know that both chicken and pigs has 1 head
⇒1c + 1p = 40
⇒c + p = 40 .........(1)
Also, we know
Chicken has 2 legs whereas pigs have 4 legs
⇒2c + 4p = 110
Divide the whole equation by 2, we get
⇒c + 2p = 55 .............(2)
∴ we get
c + p = 40 .........(1)
c + 2p = 55 .............(2)
subtract equation (1) from equation (2) , we get
c + 2p - ( c+ p) = 55 - 40
⇒c + 2p - c - p = 15
⇒p = 15
Now,
Put the value of p in equation (1), we get
c + 15 = 40
⇒c = 40 - 15
⇒c = 25
∴ we get
c = 25
p = 15
So, Total pigs in the farm = 15
Total chickens in the farm = 25
What is the distance between (4, 7) and (-8, 3)? Round to the nearest tenth.
Answer:
The distance is approximately 12.6.
Step-by-step explanation:
Moving from (-8, 3) to (4, 7), we see x (the horizontal dimension) increasing by 12 and y (the vertical dimension) increasing by 4. Think of 12 and 4 as the legs of a right triangle whose hypotenuse represents the distance between these two given points.
This distance, from the Pythagorean Theorem, is
d = √(12^2 + 4^2) = √(144 + 16) = √160 = √16√10.
The desired distance is approximately 12.6.
