5) 6x + 5y =-15

Need help it’s writing linear equations!!

Answer:

"line" a straight line graph is always linear once the line isn't straight, it'll no longer be called a line and will never be linear anymore

Answer:

it is linear because it has a constant rate of change

Step-by-step explanation:

Answer:

13 yards

Step-by-step explanation:

Required distance moved from original position should be ≥ 10 yards in other to get a first down.

Run on first play = 6 yards

Second play = - 9yards

The least number of yards needed on third play :

Let yard needed on third play = x

First play + second play + third play = 10

6 + (-9) + x = 10

6 - 9 + x = 10

-3 + x = 10

x = 10 + 3

x = 13 yards

At least 13 yards is needed on third playbto get a first down.

Answer:

x=5

Step-by-step explanation:

6(5)= 30

Answer:

54 cents

Step-by-step explanation:

The best way to solve this is by writing this as a fraction...

24/44

Next, we should divide both sides by their GCF (Greatest Common Factor) Which in this case is 4.

Now, our fraction is...

6/11

So, our final answer is 6/11 or 0.54 repeating or 54 cents

Hope this Helps!!! :)

Let me know in the comment section if I should change anything or if this answer was perfect!!!

Answer:

2.2

Step-by-step explanation:

the equation was not the only way that could change in a single year of growth

we have:(x, y1)=(1,0)

(x2,y2)=(0,1)

then the equation of circle is

(x-1)(x-x2)+(y-y1)(y-y2)=0

=(x-1)(x-0)+(y-0)(y-1)=0

=x2-x+y2-y=0

=x2++y2-x-y=0.

Hence this is the answer.

Answer:

True

Step-by-step explanation:

7y and 8y are like terms, so you can add them together

True.

How? By combining like terms.

7y + 8y = what?

We keep the variable y and simply add the numbers.

7 + 8 = 15

We now include y in our answer.

So, 7y + 8y = 15y.

Answer:

a) $7.50

b) 10 miles

Step-by-step explanation:

a)

y=mx+b

y=$29.50

x=8

m=$2.75

b=unknown

29.50=2.75(8)+b

29.50-22=22-22+b

7.50=b

Check:

2.75(8)+7.50=29.50

b)

y=$35

x=unknown

m=2.75

b=7.50

35-7.50=2.75x+7.50-7.50

27.5/2.75=2.75/2.75x

10=x

Answer:

y=-3/2+1

Step-by-step explanation:

Answer:

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

x + y : x - y = 3 : 2

Therefore,  x + y : x - y= 3 : 2 is proved.

Step-by-step explanation:

Given

x + y : x - y = 3 : 2

As

[tex]x + y = 3[/tex]

[tex]x - y = 2[/tex]

Solving to find x and y

[tex]\begin{bmatrix}x+y=3\\ x-y=2\end{bmatrix}[/tex]

[tex]x-y=2[/tex]

[tex]-[/tex]

[tex]\underline{x+y=3}[/tex]

[tex]-2y=-1[/tex]

[tex]\begin{bmatrix}x+y=3\\ -2y=-1\end{bmatrix}[/tex]

solve for y

[tex]-2y=-1[/tex]

Divide both sides by 2

[tex]\frac{-2y}{-2}=\frac{-1}{-2}[/tex]

[tex]y=\frac{1}{2}[/tex]

[tex]\mathrm{For\:}x+y=3\mathrm{\:plug\:in\:}y=\frac{1}{2}[/tex]

[tex]x+\frac{1}{2}=3[/tex]

[tex]x+\frac{1}{2}-\frac{1}{2}=3-\frac{1}{2}[/tex]

[tex]x=\frac{5}{2}[/tex]

so

[tex]x=\frac{5}{2},\:y=\frac{1}{2}[/tex]

Thus,

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

x + y : x - y = 3 : 2

Therefore,  x + y : x - y= 3 : 2 is proved.

The curve is y = sqrt{x}.

Replace x in the curve with 1 and then with 4 to find your point.

y = sqrt{1}

y = 1

First point (1, 1).

y = sqrt{4}

y = 2

Second point (4, 2).

Take it from here.

Answer:

well, if we want to know the measure angle c. we need to know the other angles measures. We know that c. is 57 more than a. and b.  

So, if the triangle is 180 degrees in total, than we need to subtract 57 frm 180 to get 123. Now we divide that by 2 because that is what the other 2 angles will measure. 123 divides by 2 is 61.5.

now we subtract 61.5 from 180 to get 118.5

now to subtract 61.5 again because the 2 angles are the same measure. 118.5-61.5 is 57. so it cant be any of the answers you provided if angle a and b are the same

Answer:

F. Outta. Here

Step-by-step explanation:

Answer:

a. 260m

b. 50m

Step-by-step explanation:

First, triangle POQ and triangle PNR are similar triangles, b/c they have one same angle(OQP), and OQ//NR.

Therefore, OP/OQ = NP/NR.

NP = OP + ON = 175 + 175 = 350

(a) 175/130 = 350 /NR, NR = 260

(b) 175/ (X+10) = 350/ (3X+5) , x = 15, NR = 50

The graph's y-intercept is -9, which is the zero of g.

Answer:

x = -24

Step-by-step explanation:

1. Subtract 2 from -46 to cancel out the addition. 2x = -48

2. Divide both sides by 2. x = -24

Answer:

39=6t+3f+e

39=19f+1

5 touchdowns, 3 extra points, and 2 field goals.

Step-by-step explanation:

e=f+1

6t=15f

39= 6t   +3f   +e

       ^       ^      ^

39=(15f)+(3f)+(f+1)           |             e=f+1                     |                      6t=15f

39=19f+1                         |             e=2+1                    |                      6t=15(2)

38=19f                            |             e=3                        |                      6t=30

Answer:

A and D

Step-by-step explanation:

When you have an equation that has an x on one side with other things you do the opposite of the thing on the same side as the x. You would add 5 to 17 then you would divide by 4 to seperate the four from the x.

In functions one input has only one output. Since 3 has two outputs it is not a function.

Answer: 201.06

Step-by-step explanation: The formula is pi times the radius squared.

You did not clearly mention the second function. So, I am assuming you meant to say that the second function has the table values such as:

x           y

0           4

-2          2

So, I am solving the question based on this information table of the 2nd function, which anyways will clear your concept.

Answer:

We conclude that the rate of change of a function '1' is greater than the rate of change of function '2'.

Step-by-step explanation:

Given the function 1

[tex]y = 2x + 6[/tex]

Comparing the function with the slope-intercept form of the line equation of a linear function

where m is the rate of change or slope of the line

so

[tex]y = 2x + 6[/tex]

rate of change = m = 2

Now, given the function 2

x           y

0           4

-2          2

Taking the slope of the two points in the table

(0 4), (-2, 2)

[tex]\mathrm{Slope\:between\:two\:points}:\quad \mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]\left(x_1,\:y_1\right)=\left(0,\:4\right),\:\left(x_2,\:y_2\right)=\left(-2,\:2\right)[/tex]

[tex]m=\frac{2-4}{-2-0}[/tex]

[tex]m=1[/tex]

So, the rate of change or slope of the function 2 is: m = 1

Hence, we observe that:

As the rate of change of a function '1' is greater than the rate of change of function 2.

i.e.

m = 2 > m = 1

Therefore, we conclude that the rate of change of a function '1' is greater than the rate of change of function '2'.
