Is (0,5) a solution to the equation y=2x?​

Answers

Answer 1
Answer:

Answer:

No.

Step-by-step explanation:

If (0,5) is a solution to y=2x, then 5=2(0) has to be true.

It is not because 5=2(0) is not true.

2(0)=0 and 0 is definitely not 5.

An example of a point on y=2x is (5,10) since 10=2(5) is true.

Answer 2
Answer:

Answer:

No

Step-by-step explanation:

The coordinate points are x and y.

So, in this case, 0 would be x and 5 would be y.

We can substitute those numbers into our equation to get:

5=(2)(0)

2 multiplied by 0 equals 0.

0 CANNOT equal 5.

Therefore, your answer is NO, (0,5) isn't the solution to the equation y=2x.

If h(x) = -2x+5/4, find h(x) = 3/4

Answers

Answer:

x=(1)/(4)

Step-by-step explanation:

So we have the function:

h(x)=-2x+(5)/(4)

And we want to find h(x)=3/4.

So, we want to find the value of x such that h(x) equates to 3/4.

So, substitute 3/4 for h(x):

(3)/(4)=-2x+(5)/(4)

First, subtract both sides by 5/4. The right will cancel.

(3)/(4)-(5)/(4)=-2x+(5)/(4)-(5)/(4)

Subtract on the left:

-(2)/(4)=-2x

Reduce on the left:

-(1)/(2)=-2x

Now, multiply both sides by -1/2. The right will again cancel:

-(1)/(2)(-(1)/(2))=-(1)/(2)(-2x)

Multiply on the left:

x=(1)/(4)

So, for h(x) to be 3/4, the value of x is 1/4.

And we're done!

Answer:

x = 1/4

Step-by-step explanation:

We are given the function as h(x) = - 2x + 5/4. If we have to determine h(x) = 3/4 given this function, let's substitute this value into our function and solve for 'x.' This will be our solution -

3/4 = - 2x + 5/4,

If we subtract 5/4 from either side : - 2x = - 1/2

Now divide either side by - 2 : x = 1/4

Therefore our solution is x = 1/4

Which graph represents the compound inequality

Answers

Answer: C

Step-by-step explanation:

When looking at compound inequalities, the inequalities are very important. You can see that on the graphs, there are some points that have a white open circle and others have blue, closed circle. The 2 different circles tells you the inequality itself. If you see ≤ or ≥, it is a closed circle. This is a closed circle because it is less than/greater than or equal to. That means it is also equal to the point, therefore it is a closed circle. If you see < or >, it is an open circle. That means it is not closed because it is greater than. It is not equal to on that specific point.

Now that we have covered the basics, we can start to eliminate. our first condition is n<-2. Above, we have established that < is an open circle. We can eliminate A and B because the points on -2 are both closed circles.

That leaves us with C and D. Since C and D both follow the points, let's look carefully at what the inequality tells us. n<-2 means n is less than -2. This means the arros should be pointing in the left side. As you go more towards the negative, the smaller the number becomes.

We can eliminate D because at -2, the numbers are going towards the right, not the left.

Therefore, our answer is C.

When you solve any equation always remember to use PEMDAS (Parentheses Exponents, Multiplication, Division, Addition and Subtraction) use also move left to right. The correct way to solve this is

2(4-16)-30

2(-12)-30

Hope this helped

Answer:

Step-by-step explanation:

Third line. "24 - (-30)" has to multiply 2 with -12, so it would be "-24" and not "24".

2(4 - 16) - (-30)

2(-12) + 30

-24 + 30 = 6
