Answer:

a total of 9 days

Step-by-step explanation:

20% of 45 is 9

answer

=9days

step by step explanation

20% is always over 100,so you are to do 20 over a hundred of 45 days....since 45 can't divide 100 do 20

[tex] \times [/tex]

45 divide by one hundred and the final answer will be 9

Answer:

I don't think it is

Step-by-step explanation:

I checked with desmos graphing calculator and the line produced is a parabola. I believe the y^2 made it into a parabola

No,  5x+y^2=25 is not a linear equation.

For the given equation;

5x+y^2=25

the highest power of the equation is 2.

Thus, the given equation is a quadratic equation or 2 degree equation.

Therefore, the given equation is not a linear equation.

Step-by-step explanation:

Slope= - 4/7

y-intercept: 1

The slope is negative. 4 down from y=1 and seven to the right and 4 up from y=1 and 7 to the left. You only need two points to trace a line.

Answer:

-32

Step-by-step explanation:

if we multiply - 2 and -6 it becomes positive so it will be 12.

-2 multiply 22 will be -44

12 - 44 is -32.

answer : -32

you distribute so you do -2 times -6 which is 12. then -2 times 22 which is -44.

you end up with 12 - 44, which equals -32.

Answer:

The slope is 4 or 4/1.

Step-by-step explanation:

Since these are all in numbers evenly divisible by 10, we can go ahead and make this easier by dividing everything by 10. When we do this, we can see a point crossing an intersection at (3,1), or if you left it, (30, 10). Next, we can see another point crossing another intersection at (4,5) or (40, 50). Since we have two points that are easy for us to subtract, we can use the slope formula. The formula is as follows: y2-y1 / x2-x1. We can pick which of these we want to be 1 or 2, but whichever one we pick has to be 1 or two on both the top on the bottom. for example, I did (50-10) / (40-30). That gets us 40/10. If you divided by ten in the first place, you would get 4/1. From there, if you have the bigger answer, you need to simplify to simply 4. The shorter answer doesn't need to be simplified because we already simplified. I hope this helps!

Answer: 3

Step-by-step explanation: 8 + (-5) is the same as saying 8 - 5 and 8-5 = 3

8 + (-5)

A negative and a positive make a negative therefore 8 + (-5) changes to

8 - 5

8 - 5 = 3

Answer: 3

Answer: See explanation

Step-by-step explanation:

Do you mean the greatest common factor (GCF), or the lowest common multiple (LCM).

If you mean GCF, then it is 1 because 7 is a prime number and has two facotrs (1 and itself) and since 9 isn’t divisible by 7, the GCF must be 1.

If you mean the LCM, the answer is 63. Using prime factorisation, we find the lowest prime factor of both numbers:

9 = 3^3

7= 7^1

Then, we multiply these together to give 63.

You cannot have a GCM, because you can’t find a greatest common multiple as numbers go on forever.

I hope this helps!

Answer:

y=x+3

Step-by-step explanation:

Start with the slope equation [tex]\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]

Since the first point is actually further along the x-axis that x-value becomes [tex]x_{2}[/tex] and its corresponding y-value is [tex]y_{2}[/tex]

[tex]\frac{9-8}{6-5}[/tex]=[tex]\frac{1}{1}[/tex]

The slope for the equation is just one so now find the y-intercept by rearranging the slope-intercept equation.

y=mx+b

y-mx=b

Now Substitute either point in to find b

9-1(6)=b

9-6=b

b=3

Your y-intercept is 3 so now we can write the slope-intercept equation for the two points:

y=x+3

Answer is C

Andy's Y value increases 2 times more

Answer:

B)

Step-by-step explanation:

If you look at Kate's y column, you will see that her pattern goes by 2,4,6 and 8.

It increases by 2.

At the same rate, Andy's increases by 4.

Therefore, B would be the correct answer.

Answer:

w = 20

Step-by-step explanation:

2 (3w - 6) = 5w + 8

distribute the 2

6w - 12 = 5w + 8

subtract 5w from both sides

w - 12 = 8

add 12 to both sides

w = 20

Answer:

The value of w is 20.

Step-by-step explanation:

Solution :

[tex]{\longmapsto{\tt{2(3w - 6)=5w + 8}}}[/tex]

[tex]{\longmapsto{\tt{(3w \times 2 )- (6 \times 2)=5w + 8}}}[/tex]

[tex]{\longmapsto{\tt{(6w)- (12)=5w + 8}}}[/tex]

[tex]{\longmapsto{\tt{6w - 12=5w + 8}}}[/tex]

[tex]{\longmapsto{\tt{6w - 5w = 8 + 12}}}[/tex]

[tex]{\longmapsto{\tt{w = 20}}}[/tex]

Hence, the value of w is 20.

Tina charges $39 for 4 hours

The given parameters are:

[tex]Base = 15[/tex] --- amount charged for the first hour

[tex]Rate = 8[/tex] --- amount charged for the extra hours

If Tina babysits for 4 hours, it means that:

Step-by-step explanation:

Answer:

It would cost $39 to serve 24 people

Step-by-step explanation:

If the recipe makes enough stew for 6 people, and the ingredients cost $9.75, then for 24 people it will cost $x. You can write this statement as

6 people - $9.75,

24 people - $x.

Or as proportion,

6/24=9.75/x

Find x:

6·× =9.75·24,

x=9.75·24/6=9.75·4=39

Answer: It would cost $39 to serve 24 people
