Which of the following could be the graph of the equation y= -2x + 5? How do you know??(plz answer!!)
Answer:
The answer is c.
Step-by-step explanation:
This is because the slope is a negative, and since letter a, has a positive slope, it's out of the picture. Just by the looks of b, you can tell that the why intercept isn't 5. It looks like its y-intercept is 0. Letter d, also doesn't have a positive y-intercept so it's also out of the picture. Which leaves letter c. It has a positive slope and it looks like it has 5 as a y-intercept.

Step-by-step explanation:
If x = 7 and y = 4, then x + 2y =
Given that if x = 7 and y = 4, the value of x + 2y = 15
Given the following:
x = 7
y = 4
Required:
Find the value of x + 2y.
Therefore, substitute x = 7 and y = 4 into the algebraic expression, x + 2y.
Thus, plug in the values into the expression:(7) + 2(4) = 7 + 8
x + 2y = 15
Therefore, given that if x = 7 and y = 4, the value of x + 2y = 15

What is the unit rate?Unit rate is the ratio of two different units, with denominator as 1. For example, kilometer/hour, meter/sec, miles/hour, salary/month, etc. Arithmetic is probably the most basic and ancient branch of mathematics and is quite commonly used in our day-to-day life.
Given here: Cam 1 clicks 30 pics in 5 secs
∴ Unit rate of Cam 1= 30/5
=6 pics/sec
Similarly we can find
Unit rate of Cam 2=9 pics/sec
Unit rate of Cam 3= 7 pics/sec
Hence, The respective unit rates are 6,9,7

Answer:
y = -x + 9
Step-by-step explanation:
Since the line is going down, you can safely assume that it is a negative slope function. The y-intercept is at (0, 9), so your final slope function should be y = -x + 9.

Two buildings are facing each other on a road of width 12 metre . From the top of the first building, which is 10 metre high , the angle of elevation of the top of the second is found to be 60°. What is the height of the second building ?
So easy question
Can u people solve ?
I dont think so
Answer:
[tex]\displaystyle 10 + 12\sqrt{3}[/tex] metres
Step-by-step explanation:
You are finding the height of the building with an angle of elevation, therefore we need to solve for EC to add it to BA [10 metres] and use TRIGONOMETRIC RATIOS to arrive at our conclusion. Just in case you have forgotten what they were, here they are:
[tex]\displaystyle \frac{OPPOSITE}{HYPOTENUSE} = sin\:θ \\ \frac{ADJACENT}{HYPOTENUSE} = cos\:θ \\ \frac{OPPOSITE}{ADJACENT} = tan\:θ \\ \frac{HYPOTENUSE}{ADJACENT} = sec\:θ \\ \frac{HYPOTENUSE}{OPPOSITE} = csc\:θ \\ \frac{ADJACENT}{OPPOSITE} = cot\:θ[/tex]
We can now solve for EC:
[tex]\displaystyle cot\:60 = \frac{12}{EC} → ECcot\:60 = 12 \\ \\ \frac{ECcot\:60}{cot\:60} = \frac{12}{cot\:60} → 12\sqrt{3} = EC[/tex]
OR
[tex]\displaystyle tan\:60 = \frac{EC}{12} → 12tan\:60 = EC → 12\sqrt{3} = EC[/tex]
Now that you have solved for EC, you can now add it to your original 10 metres to get [tex]\displaystyle 10 + 12\sqrt{3}[/tex] metres. As a decimal, you would get [tex]\displaystyle 30,78460969...[/tex] metres. You can go ahead and round this off if necessary.
** The reason why the cotangent [or tangent] ratio was used was because EA is equivalent to DB by the definition of a rectangle. It has two pairs of parallel and congruent sides with four right angles. Plus, that is the adjacent side of the triangle, while EC is the opposite side of the triangle, so we knew our ratios were correct.

A car uses a litre of petrol to travel 4km. How many litres will it use to travel 32 kilometres.
Given that,
A car uses a litre of petrol to travel 4 km.
To find,
How many litres will it use to travel 32 kilometres.
Solution,
We have,
1 litre = 4 km
or
1 km = (1/4) litre
Let it will use x litres to travel 32 km.
32 km = (32/4) litres
= 8 litres
Hence, 8 litres it will use to travel 32 km.

On a windy morning, a hot air balloon starts rising and flying away from the top of a hill. The altitude, h, in feet, of the balloon x hours after starting its ascent from the hill, can be modeled by the function:
Part A: What is the y-intercept for this function? What does the y-intercept represent in the given situation? Use your equation to explain how you found your answer.
h(x)=-16x2+64x+80
Answer:
The y-intercept is y = 80feet. The initial height of the balloon is 80feet.
Step-by-step explanation:
[tex]h(x)=-16x^2+64x+80[/tex]
The y-intercept of the function happens when the x-value = 0. So let's plugin x=0 into the function:
[tex]h(x)=-16x^2+64x+80\\h(x)=-16(0)^2+64(0)+80\\h(x)=80[/tex]
The y-intercept is y = 80feet
x represents the number of hours after starting its ascent from the hill, so x = 0hr means when the balloon is just starting to ascent. At the start of the ascent, the balloon has an altitude of 80feet. The initial height of the balloon is 80feet.
The y-intercept is y = 80feet.
The initial height of the balloon is 80feet.
Calculation of the y-intercept and initial height:Since the equation is [tex]h(x)=-16x^2+64x+80[/tex]
So here x = 0
So
[tex]h(x)=-16(0)^2+64(0)+80[/tex]
= 80
Here, The y-intercept is y = 80feet
Also,
x means the number of hours after starting its ascent from the hill

Answer:
10 games
Step-by-step explanation:
The team can expect to win 6 matches.
What is ratio?A ratio is a way to show a relationship or compare two numbers of the same kind. We use ratios to compare things of the same type.
Given that, The ratio of wins to losses for the spartan football team is 3:5. and this trend continues, they play a total of 16 games,
Let they won 3k games and loose 5k games.
Then,
3k+5k = 16
8k = 16
k = 2
Therefore, they lose 5·2 = 10 matches and won 3·2 = 6 matches.
Hence, the team can expect to win 6 matches.
