I dont get it yall help​

Mathematics
1 answer:
docker41 [41]3 years ago
5 0

Answer:

(-2,6)

Step-by-step explanation:

The solution to the system of equations should be true for both equations.  This means that if you substitute -2 into both equations, you should get 6 as the y value for both equations.

They gave you a graph, and to find the solution from the graph, you just look at which point is shared by both lines, or at which point both lines intersect.

There is also a mathematical way to do it using substitution and elimination, but you should master the graphing method first before moving onto those.

I HAVE 1 MORE DAY TO TURN THIS IN SO HURRY
SCORPION-xisa [38]

Hello there! I am EnjoyingLife, and I hope you find my answer helpful.

First of all, since all books cost less than $5, the most expensive a book could be is $4.99 (remember, less than, not less than or equal to)

Now, let's write an inequality to represent the cost of books.

We know that all books cost less than $5.

We have a sign for "less than". It's "<"

Thus,

p<5

Hope it helps!

Have an awesome day!

Good luck!

Passing through (-2,1 ) and perpendicular to<br> 4x + 7y + 3 = 0.
Lunna [17]

Answer:

<h2>7x - 4y + 18 = 0</h2>

Step-by-step explanation:

The slope-intercept form of an equation of a line:

y=mx+b

m - slope

b - y-intercept

========================================

Let

k:y=m_1x+b_1\\\\l:y=m_2x+b_2\\\\l\ \perp\ k\iff m_1m_2=-1\to m_2=-\dfrac{1}{m_1}\\\\l\ \parallel\ k\iff m_1=m_2

========================================

We have the equation of a line in a general form (Ax + By + C = 0)

Convert it to the slope-intercept form:

4x+7y+3=0             <em>subtract 7y from both sides</em>

4x+3=-7y         <em>divide both sides by (-7)</em>

-\dfrac{4}{7}x-\dfrac{3}{7}=y\to m_1=-\dfrac{4}{7}

Therefore

m_2=-\dfrac{1}{-\frac{4}{7}}=\dfrac{7}{4}

We have the equation:

y=\dfrac{7}{4}x+b

Put the coordinates of the point (-2, 1) to the equation, and solve for <em>b</em> :

1=\dfrac{7}{4}(-2)+b

1=-\dfrac{7}{2}+b     <em>multiply both sides by 2</em>

2=-7+2b           <em>add 7 to both sides</em>

9=2b            <em>divide both sides by 2</em>

[te]x\dfrac{9}{2}=b\to b=\dfrac{9}{2}[/tex]

Finally:

y=\dfrac{7}{4}x+\dfrac{9}{2} - <em>slope-intercept form</em>

Convert to the general form:

y=\dfrac{7}{4}x+\dfrac{9}{2}         <em>multiply both sides by 4</em>

4y=7x+18      <em>subtract 4y from both sides</em>

0=7x-4y+18

Graph f(x)=−3/4x−4 . Use the line tool and select two points to graph the line.
lions [1.4K]

Answer:

Two points on the line would be (0, -4) and (4, -7)

Step-by-step explanation:

In order to find this, we can start at the y-intercept. The y-intercept is the constant at the end of the equation. In this case it is -4, which gives us the first point of (0, -4).

We can find the second point by using the numerator of the slope to determine how much we go up or down (-3) and the denominator for how much we go left to right (4). So we add the 4 to the x value and add the -3 to the y value.

(4, -7)

Vikentia [17]

Answer:

$2.47

Step-by-step explanation:

Pretend if Mr. Yasin didn't pay for the 3rd box, find out how much he had left after paying for the first 2 boxes.

9.43 - 3.99 - 2.97 = 2.47
