Answer:

the product of 4 and a number decreased by 7

Step-by-step explanation:

Answer:

y = 2/3x - 9

Step-by-step explanation:

Slope-Intercept Form: y = mx + b

m - slope

b - y-intercept

Step 1: Define

Point (9, - 3)

2x - 3y = -6

Step 2: Rewrite given equation

-3y = -2x - 6

y = 2/3x + 2

So our m = 2/3 (Parallel lines have the same slope but different y-intercepts)

Step 3: Find y-int of parallel line

y = 2/3x + b

-3 = 2/3(9) + b

-3 = 6 + b

b = -9

Step 4: Write parallel line equation

y = 2/3x - 9

Answer:

y=x+4

Step-by-step explanation:

Use slope formula: (y2-y1)/(x2-x1)

(6-4)/(2-0)

2/2

1

Slope Intercept Form: y = m(slope) times x plus b(y-intercept)

y=1x+b

Plug in one of your points into the equation:

4=1(0)+b

4=0+b

4=b

Final Answer: y=x+4

Sorry if this is confusing; this is my first answer.

Answer: A

Step-by-step explanation: The standard form for linear equations in two variables is Ax+By=C. For example, 2x+3y=5 is a linear equation in standard form. When an equation is given in this form, it's pretty easy to find both intercepts (x and y).

Answer:

A)

Step-by-step explanation:

Trinomial expression had 3 terms. Here x + 7 has only 2 terms. So, it is not a trinomial

Answer:

There's no way to answer this question 100% accurately, because we don't know your teacher's grading scale, or how much tests and quizzes are weighted for your grade in the class. That being said, one test shouldn't bring your grade down too much. As the year goes on, and more assignments are put in the gradebook, it will even out. If you get a 100 percent on 3 tests, and a 60 percent on one test, it evens out to a 90 percent.

Answer:

[tex]\boxed {h = -10.071}[/tex]

Step-by-step explanation:

Solve for the value of [tex]h[/tex]:

[tex]h - (-2.22) = -7.851[/tex]

The opposite of [tex]-2.22[/tex] would be [tex]2.22[/tex]:

[tex]h - (-2.22) = -7.851[/tex]

[tex]h + 2.22 = -7.851[/tex]

-Subtract both side by [tex]2.22[/tex]:

[tex]h + 2.22 - 2.22 = -7.851 - 2.22[/tex]

[tex]\boxed {h = -10.071}[/tex]

So, the value of [tex]h[/tex] is [tex]-10.071[/tex].

Answer:

$3.00

Step-by-step explanation:

7.50/5 = 1.5

12/8 = 1.5

Since each song costs $1.50 each, multiply the cost by the number of songs.

1.50(2) = 3

$3.00

Answer:

y=1/4x-1

Step-by-step explanation:

i knew the general equation of the line and i knew the slope would be a fraction because the line is rlly flat

-1 would be the b and i plugged in simple fraction values for m

i checked in desmos and they look similar

hope this helps and is correct <3

Answer:

[tex]\frac{2}{3}[/tex]

Step-by-step explanation:

For this situation we will use this equation:

[tex]m=\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

This lets us find the slope from a set of points (m being the slope of course), with each one representing a coordinate from our set. (e.g. 7 could be [tex]y_{2}[/tex])

First let's define which coordinates will represent each:

(-1,3): [tex]x_{1} ,y_{1}[/tex]

(5,7): [tex]x_{2} ,y_{2}[/tex]

Now that we have this, we can fill in our coordinates: [tex]m = \frac{7-3}{5-(-1)}[/tex]

Next we simplify: [tex]m = \frac{4}{5+1}[/tex] (double negative = positive)

And simplify some more: [tex]m = \frac{4}{6}[/tex]

Finally, we find the GCF (greatest common factor) of 4 and 6, which is 2, and divide by that to further simplify the fraction: [tex]m = \frac{2}{3}[/tex]

Therefore, the slope of the line that passes through the points (-1,3) and (5,7) is [tex]\frac{2}{3}[/tex].

Answer:

x=25

Step-by-step explanation:

since this is a triangle you would add up all the measure of this and set it equal to 180. 90 is the side with the box. so it would be 2x+15+x+90=180 then solve for x and you would get your answer.

Parallel lines have same slope

Given line, in slope intercept form

Parallel line is

Using point (5, 4) to find b

y = 2/3x + 2/3 in slope-intercept form or

Answer:

-3mn^3 and -5mn^3

Step-by-step explanation:

had it correct on my test - PLATO

Marcus  has to add -3mn^3 and -5mn^3 to complete the polynomial.

Marcus is rewriting a polynomial by combining like terms

Polynomial equation is equation of independent variables.

Here, questions seems to be incomplete.
In polynomial, it can be of maximum endless number of term or minimum 1 term. Marcus can add any number or repeat any number. And if he revised the old number than the number could be -3mn^3 and -5mn^3.

Thus, Marcus  has to add -3mn^3 and -5mn^3 to complete the polynomial.

[tex]\sf{4n=4-20}[/tex]

[tex]\sf{4n= -16}[/tex]

[tex]\sf{n=\dfrac{-16}{4}}[/tex]

[tex]\sf{n = -4}[/tex]

Hope it helps :)

Answer:

-4

Step-by-step explanation:

To solve, you need to isolate the number with the variable (in this case, 4n). To do that, get rid of the 20 on the left side. To do THAT, do the opposite which is subtract; do it to both sides. This leaves you with 4n= -16.

Now, to get rid of the 4 and be left with just the n, do the opposite of what is given. In this case, n is multiplied by 4 so divide by 4 on both sides to isolate n. This gives you the answer of -4.

Hope it helps!
