The solution to a system of linear equations is the point at which the lines representing the linear equations intersect, let's graph to determine the solution:

As we can see on the graph, the lines intersect on (5, 2). Now, let's check substituing into the equations:

\begin{gathered} \text{Subtituing y=2, into the first equation:} \\ 2=x-3 \\ x=2+3 \\ x=5 \end{gathered}

So, the solution is correct.

What is the slope of a line perpendicular to the<br> graph of the equation 5x - 3y = 2?)
Advocard [28]

The slope of a line perpendicular to the

graph of the equation 5x - 3y = 2 is -3/5.

<h3>How to find the slope of a line?</h3>

given that the equation is 5x - 3y = 2.

now write the equation in standard form y = mx + b

then -3y = 2 - 5x

y = -2/3 + 5x/3

y = 5/3x - 2/3

m 1*m 2 = - 1 is the formula for the slopes from a pair of perpendicular lines. where the slopes of the lines are m 1 and m 2.

Here m1 = 5/3 and m2 = -3/5.

Hence,the slope of a line perpendicular to the

graph of the equation 5x - 3y = 2 is -3/5.

A line had a slope of 2/3 and a y intercept at (0,14).What is the x intercept of the line?​
pychu [463]

Answer:

y=2/3x+14

Step-by-step explanation:

The standard form of an equation in slope-intercept form is y=mx+b where m=slope and b=y-intercept.

Given a y-intercept of 14 and a slope of 2/3, we can plug into the variables and get the equation y=2/3x+14

The x-intercept would be when y=0, so plugging in y=0 to the equation gets us:

0=2/3x+14

-14=2/3x

21=x

So the x-intercept is 21

ASAP!!! PLEASE HELP &amp; EXPLAIN.
Vika [28.1K]

Answer:

B

Step-by-step explanation:

the domain of a graph consists of all the input values shown on the x-axis.

so because the only parts shown on the x axis are 6 and -6 that is the answer!

hope this helps!

Use the diagram to determine which statement is true
hichkok12 [17]
A. Area of ABCD - Area of DGA = Area of DEFG
s^2 - 1/2bh = s^2
(5)^2 - 1/2(4)(3) = (3)^2
25 - 1/2(12) = 9
25 - 24 = 9
1 not equal to 9

B. Area of ABCD - Area of GHIA = Area of DGA
s^2 - s^2 = 1/2bh
(5)^2 - (4)^2 = 1/2(4)(3)
25 - 16 = 1/2(12)
9 not equal to 6

C. Area of ABCD + Area of DGA = Area of GHIA
s^2 + 1/2bh = s^2
(5)^2 + 1/2(4)(3) = (4)^2
25 + 1/2(12) = 16
25 + 6 = 16
31 not equal to 16

D. Area of DEFG + Area of GHIA = Area of ABCD
s^2 + s^2 = s^2
(3)^2 + (4)^2 = (5)^2
9 + 16 = 25
25 = 25

The answer is D.

Find the x and y intercept of 8x+10y=15. NO LINK TO ANSWER PLEASE TYPE
oee [108]

Answer:

x intercept: 15/8 and yintercerpt is 3/2

Step-by-step explanation:

to find y intercept you have to put equation in standard form.

10y=-8x+15

y=--4/5x+3/2

x intercept is when y=0, so we plug in 0

0=-4/5x+3/2

4/5x=3/2

x=15/8
