Consider the following Expression.
-3(y+3)=2y+3
What Is the value of y?
Answer:
y= -12/5
Decimal form: -2.4
Step-by-step explanation:
Distribute the negative 3 on the left side
-3y-9=2y+3
Add 3y to both sides
-9=5y+3
Subtract 3 from both sides
-12=5y
Divide by 5 on both sides
y=-12/5 or -2.4
hello I need help with graphing my functions it's y = 2x + 3 but I need to graph it
The variable x is a placeholder for a number
Let's say we replace x with 0
y = 2x+3
y = 2(0)+3
y = 0+3
y = 3
This means x = 0 and y = 3 pair up together. In short, the point (0,3) is on the line.
--------------
Let's repeat for x = 1
y = 2x+3
y = 2(1)+3 ... replace x with 1
y = 2+3
y = 5
So (1,5) is another point on the line
---------------
We can keep this process going to generate as many points as we want. But to graph a linear equation like this, we only need two points at minimum.
Graph both (0,3) and (1,5). Then draw a straight line through them both. The graph is shown below.
Last one please this is due in like 5 mins i’m gonna cry
Answer:
A:25
Step-by-step explanation:
Was gonna brute force every question with a calculator but luckily A was correct. Substituted 25 for x and found all the angles. 5x was 125, which I subtracted from 180 to find the interior angle, 55°. 3x was 75.
75+55+50=180°
Which of these equations is in POINT-SLOPE form?
m=(2−4)(5−3)
m is equal to the fraction with numerator open paren 2 minus 4 close paren and denominator open paren 5 minus 3 close paren
y=4x+7
y is equal to 4 x plus 7
y−3=23(x−4)
y minus 3 is equal to 2 thirds times open paren x minus 4 close paren
3 x + 5 y = 8
3 x + 5 y = 8

Answer:
the answer is -2.1
Step-by-step explanation:
you get this by putting that -4 where the x is and solving so it would look something like this
1.7x+4.7 for x= -4
1.7(-4) + 4.7
-6.8 + 4.7
-2.1

-3x2- 24x - 36
What expression is equivalent to the given expression?
Answer:
-3 2 6
Step-by-step explanation:
Consider this expression.
-3x2- 24x - 36
What expression is equivalent to the given expression?
-3 (x + 2)(x+6)
Drop down answer is in bold
The equivalent expression will be : - 3 (x + 2) (x + 6)
We have the following expression -
[tex]-3x^{2}[/tex] - 24x - 36
We have to find out the equivalent expression of above expression.
Expand the following expression - (x + 2)(x + 4).Above expression can be expanded in the following way -
(x + 2)(x + 4) = x(x + 2) + 4(x + 4) = [tex]x^{2}[/tex] + 2x + 4x + 16 = [tex]x^{2}[/tex] + 2x + 16
According to question -
[tex]-3x^{2}[/tex] - 24x - 36
- 3 ([tex]x^{2}[/tex] + 8x + 12)
-3 ([tex]x^{2}[/tex] + 6x + 2x + 12)
-3 [x(x + 6) + 2(x + 6)]
-3(x + 2)(x + 6)
Hence, the equivalent expression will be : -3(x + 2)(x + 6)

What is the value of the expression below when z = • 3?
622 + 2z + 10
Answer:
632.6
Step-by-step explanation:
Z = .3 right? It looks weird on my screen
Anyway, if z is .3 than this is how to solve
First you plug in 0.3 where the z would go, making the expression 622 + 2(0.3) + 10. Then you solve! (below)
622 + 2(0.3) + 10.
622 + 0.6 + 10.
622 + 10 + 0.6
632 + 0.6
632.6
