Solve the system by substitution.
y = 5x
y = 9x + 4
Answer:
(-1, -5)
Step-by-step explanation:
[tex]\left \{ {{y=5x} \atop {y=9x+4}} \right.[/tex]
1. We must calculate x, for that we must substitute y, so we have:
5x=9x+4
2. Now we solve the equation.
5x-9x=4
-4x=4
x=-1
3. Now we must calculate y
y=5x
y=5(-1)
y=-5
And the answer is (-1, -5)

Graph the line with a slope of 2/3 that contains the point (−3,−5)
Answer:
Step-by-step explanation:
So for the given information, it would be easiest to use slope-intercept form, which is y=mx + b, where m is the slope and b is the y-intercept.
We can plug in 2/3 for the slope, because we are given that.
y=2/3x + b.
To find the y-intercept, plug in the given point for x and y and solve for b.
-5 = 2/3 · (-3) + b
-5 = -2 + b
b = -3
So now we have the complete equation of the line.
y = 2/3x -3
Now to graphing.
We can put the y-intercept, (0, -3), and the given point, (-3, -5) on a graph.

Identify whether the expressions are equivalent or not equivalent: 7y – 15 + 2y and 9y - 15
Answer:
Yes, the two expressions are equivalent
The given expression 7y - 15 + 2y and 9y - 15 are equivalent.
What is equivalent expression?
Two algebraic expressions are said to be equivalent if their values obtained by substituting the values of the variables are same, even they look different.
According to the given question.
We have two expressions
[tex]7y - 15 + 2y ...(i)[/tex]
And, [tex]9y - 15 ...(ii)[/tex]
The expression (i) can be written as
[tex]7y - 15 + 2y[/tex]
[tex]=(7y + 2y)-15[/tex] (adding the like terms)
[tex]= 9y -15[/tex]
Hence, the given expression 7y - 15 + 2y and 9y - 15 are equivalent.

Answer:
they would both be 61°
Step-by-step explanation:
when the angles make out a straight line it equals to 180 and 180 subtracted to 119 comes out to 61 and both b and c are vertical angles which would make them congruent
Answer:
B= 61 C=61
Step-by-step explanation:
You can see how there is a straight line (180 degrees) so if you do 180-119 you get 61 degrees
-6p-3=9 what does p equal
Answer:
-2
Explanation:
-6 x -2 = 12
12 - 3 = 9
Answer:
p=-2
Step-by-step explanation:
Move the -3 to the other side by adding 3 on both sides:
-6p-3+3=9+3
The equation now looks like this:
-6p=12
Divide -6 on both sides:
-6p/-6=12/-6
The equation now looks like this:
p=-2 which is the answer

PLEASE HELPPPP!!! Find the measure of angle A
========================================================
Explanation:
The three angles of this triangle are
20x9026x-2The square angle marker represents 90 degrees. It's also referred to as "a right angle".
As a rule, the three angles of any triangle always add to 180. Let's use this fact to solve for x
(angle1)+(angle2)+(angle3) = 180
(20x)+(90)+(26x-2) = 180
(20x+26x) + (90-2) = 180
46x+88 = 180
46x = 180 - 88 .... subtract 88 from both sides
46x = 92
x = 92/46 ........ divide both sides by 46
x = 2
Now that we know what x is, we can find angle A
angle A = 20x = 20*2 = 40 degrees
-------------
As extra info, we could also find the other angle with this x value
26x - 2 = 26*2 - 2 = 52 - 2 = 50 degrees
The three angles of the triangle are: 40, 50, 90 which add to 40+50+90 = 180. This helps confirm our answer.
