Answer:
6 movies
Step-by-step explanation:
45-30=15 spent on movies
divide the 15 by 2.5 to get 6.
$30+$2.50m=$45
where m is the amount of movies
Answer:
let he purchaseed x movies
30 + 2.5x = 45
or 2.5x = 15
x=15/2.5 =6

A coordinate plane with a line passing through the points (0, negative 4) and (2, 2).
What is the equation of the graphed line written in standard form?
–3x + y = –4
y = 3x – 4
y + 3x = 4
3x – y = 4
Answer:
The answer is D
Step-by-step explanation:
The only logical explanation
Equation of the graphed line passing through the points (0, - 4) and (2, 2) is equals to [tex]y = 3x - 4[/tex].
What is coordinate plane?" Coordinate plane is defined as the two dimensional plane formed by number line named x-axis and y-axis."
Formula used
Standard equation of the line
[tex]\frac{y-y_{1} }{x-x_{1} } =\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]
According to the question,
Points passing through coordinate plane,
[tex](x_{1} ,y_{1} ) = (0,-4)\\\\(x_{2} ,y_{2} ) = (2,2)[/tex]
Substitute the coordinates in the formula to get the equation of line ,
[tex]\frac{y-(-4) }{x-0 } =\frac{2-(-4) }{2-0}[/tex]
⇒ [tex]\frac{y+4 }{x } =\frac{6 }{2}[/tex]
⇒[tex]y + 4= 3x[/tex]
⇒[tex]y=3x-4[/tex]
Hence, the equation of the line is [tex]y=3x-4[/tex].

the product of -3 and the square of a number decreased by 8.
Answer:
[tex]n^{2}(-3) -8[/tex]
Step-by-step explanation:
So the "product of" means the answer to a multiplication problem. That means -3 is being multiplied by a number which is squared. I used the variable "n" for number but you could use any letter you want.
This is what we have so far,
[tex]n^{2} \\[/tex] x -3 or [tex]n^{2}[/tex](-3)
The term decreased means to reduce or subtract. Which means we are left with....

Given: f(x)=4x-9 and g(x)= 2x-3. What is the value of (f+g)(0)=?
A.-9
B.-10
C.-11
D.-12
Answer:
D. -12
Step-by-step explanation:
if f=4x-9, and g=2x-3, and the value is (f+g), then we have to add the equations. This is equal to 6x-12. And then, in '(f+g)(0)', it is asking what is the y-value at x=0. Plug in 0 into the equation, and the y-value equals -12.

(30 points) find the measure of each lettered angle a= b= c= d= e= f= g= h= i=
Answer:
a=90 b=90 c=90 d=148 e=32 f=148 g= 122 h=58 l=122
Step-by-step explanation:
a is supp. to 90 degrees, therefore it is 90 (180-90)=90.
b and c are vertical angles, therefore they are the same as the angle directly across from them
d is supp. to 32 degrees, therefore it is 148 (180-32)=148
e and f are vertical angles, therefore they are the same as the angle directly across from them
g is supp. to 58 degrees, therefore it is 122 (180-58)=122
h and l are vertical angles, therefore they are the same as the angle directly across from them

express 6^1/4 b^3/4 c^1/4 using a radical
Answer:
B
Step-by-step explanation:
[tex]6^{\frac{1}{4} } b^{\frac{3}{4} }c^{\frac{1}{4} }\\\\=(6^1b^3c^1)^{\frac{1}{4} }\\\\=(6b^3c)^\frac{1}{4} \\\\=\sqrt[4]{6b^3c}[/tex]
so answer is B
[tex]6^{\frac{1}{4} }b^{\frac{3}{4} }c^{\frac{1}{4} }[/tex] expressed as a radical is d. [tex]\sqrt[4]{(6b^{3}c )}[/tex]
To answer the question, we need to know what radicals are.
What are radicals?Radicals are roots of numbers. They are written in the form [tex]\sqrt[n]{x}[/tex] where n is the nth root of x.
Now given that we want to express [tex]6^{\frac{1}{4} }b^{\frac{3}{4} }c^{\frac{1}{4} }[/tex] as a radical, we having using the laws of indices
[tex]6^{\frac{1}{4} }b^{\frac{3}{4} }c^{\frac{1}{4} } = (6b^{3}c )^{\frac{1}{4} } \\6^{\frac{1}{4} }b^{\frac{3}{4} }c^{\frac{1}{4} }= \sqrt[4]{(6b^{3}c )}[/tex]
Thus, we have expressed it as a radical.
So, [tex]6^{\frac{1}{4} }b^{\frac{3}{4} }c^{\frac{1}{4} }[/tex] expressed as a radical is d. [tex]\sqrt[4]{(6b^{3}c )}[/tex]
