can someone help me with this one 2x2-18=0

Answer:

15

Step-by-step explanation:

for every three boys there are five girls

3 groups of 3 boys

3*5=15 girls

I think the correlation is negative because the graph is going down.

Hope this helps

Answer:

x = 128 degrees

Step-by-step explanation:

So we know that a triangle's interior angles should add up to 180 degrees.

We also know that when a triangle has that little square in a corner, that corner is equal to 90 degrees.

With these clues, we can figure out that the last interior angle is equal to:

180 - (38+90) = 52, however this isn't the answer we are looking for.

We also know that a straight line is 180 degrees. Therefore, to find the exterior angle we just subtract the interior angle from 180 degrees:

180 - 52 = 128

x = 128

Answer:

21

Step-by-step explanation:

First, add the parenthesis

2^4 + 4.50 ÷ 0.9

Second, divide 4.50 by 0.9

2^4 + 5

Third, get rid of the ^4

(2x2x2x2)

16 + 5

Answer:

All real numbers

Step-by-step explanation:

Given: 10x-2-6x=2(2x-1)

Distribute: 10x-2-6x=4x-2

Simplify like terms: 4x-2=4x-2

Subtract 4x to both sides: -2=-2

Add 2 to both sides: 0=0

All real numbers

Answer:

24.46

Step-by-step explanation:

The hundredths place is two places after the decimal. Since the thousandth place is a 9 this would round up the hundredths place to 6.

Answer:

See below

Step-by-step explanation:

I hope you wrote down the right equation using a minus sign instead of a plus.

Rounding 96.26 off to just 96  and then rounding 62.74 off to 62, you can subtract the two in your head real quick.

96 - 62 = 34

So using this estimation you can see that the answer of 159 is no where near correct.

Answer:

Slope = 2

Answer:

[tex]f = 9 \div 5c + 32[/tex]

[tex]f - 32 = 9 \div 5c[/tex]

[tex]5(f - 32) = 9c[/tex]

[tex]5(f - 32) \div 9= 9c \div 9[/tex]

Step-by-step explanation:

C = 5(F–32)/9

everything can be found in the solving hope this helps. if you have any worries or doubts don't hesitate to ask me back

Answer:C

Step-by-step explanation:

F=9/5 x C +32

F = -32 =9/5 x C

5/9 (F-32)+C

all you have to do is count them and write them in ratio

x=0 I think not 100% sure though

Answer: The equation has infinitely many solutions.

Step-by-step explanation:

With George's end result of 3=3, you can assume that the equation is set up in such a way that no matter what you plug in, you will get the same number on both sides of the equals sign, which means the solution is valid. Therefore this means that there are an infinite number of solutions.

Answer: 2/5

Explanation: Ask if you want an explanation!

      The question gives us two points, (-2, 1) and (8,5), from which we can find the slope and later the equation of the line.

Finding the Slope

The slope of the line (m) = (y₂ - y₁) ÷ (x₂ - x₁)      

                                          =  (5 - 1) ÷ (8 - (-2))    

                                          =   ⁴/₁₀

                                          = ²/₅  

Checking my answer:

We can check to see if the answer is correct by drawing the line and seeing if it passes through both points. If it does, then the slope is correct.

We can now use the point-slope form (y - y₁) = m(x - x₁)) to write the equation for this line:

                                ⇒  y - 1 =  ²/₅ (x + 2)

In the graph below (created using Desmos), the line passes through both points. This suggests that we calculated the slope correctly.

Answer:

binary codenis the easiest bro it's just 1 and 0 right?

Answer:

y=3/2x+3/2

Step-by-step explanation:

point at (-6,-5)

slope = m = 3/2

y = mx+b

(-6)=(3/2)(-5)+b >>> substituting x & y to solve for b

-6 = (-15/2)+b >>> simplify previous equation

-6 + (15/2) = b >>> isolate and solve for m

3/2 = b

therefore, the equation of the line passing through the point (-6,-5) with a slope of 3/2 is y=(3/2)x+(3/2)

What is remainder R when the polynomial p(x) is divided by (2x - 1)? is (2x - 1) factor of p(x)?

p(x) = 2x² + 3x + 1

Answer :

R = 3

and (2x - 1) not factor of p(x) because, if (2x - 1) factor of p(x) remainder R when the polynomial p(x) divided by (2x - 1) is R = 0

∴ so the answer is option A
