Answer:
f(-2) = - 4
Step-by-step explanation:
f(x) = x² + 3x - 2
f(-2) = ( -2)² + 3 *(-2) - 2
= 4 - 6 - 2
= 4- 8
= - 4

Write an inequality relating NM and NL-
NM < NL
NM<_ NL
NM > NL
NM>_ NL
Answer:
NM > LN
Step-by-step explanation:
Here, we want to write an inequality
we should beat it in mind that, the greater the angle that a side of a triangle faces, the greater its length will be relatively
as we can see, the side NM faces the greater angle of 83, relative to the side LN that faces the angle of 56;
So we can conclude that;
NM > LN

NM > LN

Answer:
X=37
Step-by-step explanation:
Add 4x+2 and 30 it equals to 180. Then you get x.
Solve the system of equations.
y=x+2
y=4x+23
Write your answer as
X=
y=
Answer:
Step-by-step explanation:
The required solutions of the given system of equations is x = -7 and y = -5.
What are simultaneous linear equations?Simultaneous linear equations are two- or three-variable linear equations that can be solved together to arrive at a common solution.
Here,
Given system of equation
y=x+2 - - - - -(1)
y=4x+23 - - - - (2)
From above equations,
x + 2 = 4x + 23
x = -7
Now,
y = -7 + 2
y = -5
Thus, the required solutions of the given system of equations is x = -7 and y = -5.

SUPER EASY
just. determine if function or not
Ok so basically if an input (x) has more than one output (y) it is NOT a function. One output having more than one input is okay though.
So G) is a function, bc for every x there is just 1 y
H) is not a function
I) is not a function either
Then the 6 below ( i can't read their numbers so they're just gonna be 1-6, top 3 from left to right then the bottom three from left to right)
1. function
2. not a function
3. function
4. function
5. not a function
6. not a function
i might be wrong, but i hope this helps!
Answer:
G-Function, H-Not a function, I-Not a Function
Step-by-step explanation:
G is the only one that doesn't repeat its x values
Which expression is equal to 21/48?
a. 1/2 x 11/48
b. 7/12 x 3/4
c. 3/48 x 7/48
d. 10/6 x 11/8
Answer:
option b
Step-by-step explanation:
21/48 reduced to it's lowest term is 7/16 and solving option b... 7/12 ×3/4 3 would divide 12 to give 4 and multiply what you have left which is 7/4 ×1/4 would be equal to 7/16

create a polynomial in the form ax^3+bx^2+cx=0 that has solutions of x=0,x=-5 and x=11, where a=3
3x^3-18x^2-165x=0
Since we are given the solutions, we can rewrite them.
x=-5 is (x+5)
x=11 is (x-11)
x=0 is just x
Now we can write our equation:
3x(x+5)(x-11)=0
*3 comes from the a being 3
Now we multiply, I’d recommend starting by using FOIL on the last two first and getting;
3x(x^2-6x-55)=0
Then distribute the 3x:
3x^3-18x^2-165x=0
Find the value of the variable(s). If your answer is not an integer, leave it in simplest radical form.
x=10/3 x=10,y=30/3 x=30.y=10/3
Answer:
Use the fact that sin(x) = opp/hyp and tan(x) = opp/adj
where opp=opposite, hyp=hypotenuse, adj=adjacent and recall sin(30)=1/2 and tan(30) = 1/sqrt(3)
sin(30) = 1/2 = 17/y
y = 17(2) = 34
tan(30) = 1/sqrt(3) = 17/x
x = 17sqrt(3)
So the answer is (d)
Note that you could have also use the Pythagorean theorem to find x instead of using tan(30).

A website received 2500 registered members in July. And the number of registered members in August decreased to 2245. What was the percentage decrease in the number of registered members?
Number of registrations a website received during July = 2500
Number of registrations a website received during August = 2245
Number by which the registrations decreased :
[tex] =\tt 2500 - 2245[/tex]
[tex] =\tt 255[/tex]
Thus, the registrations decreased by 255.
Let x be the perrcentage of decrease.
Which means :
[tex] =\tt 255 = \frac{x}{100} \: of \: 2500[/tex]
[tex] = \tt255 = \frac{x \times 2500}{100} [/tex]
[tex] =\tt 255 = \frac{2500x}{100} [/tex]
[tex] = \tt255 \times 100 = 2500x[/tex]
[tex] = \tt25500 = 2500x[/tex]
[tex] =\tt \frac{25000}{2500} = x[/tex]
[tex]\color{plum} =\tt \bold{10.2\%}[/tex]
▪︎Thus, the percentage of decrease in the number of registered members = 10.2%
