Answer:
b. The line passes through the ordered pair (0,5) and has a slope of 3.
Step-by-step explanation:
The equation given is in slope-intercept form.
[tex]y= mx+b[/tex]
m = slope
b = y-intercept
The slope is 3 in the equation. 3 is in m's spot.
[tex]y=\boxed{m}x+b\\\\y=\boxed{3}x+b[/tex]
The y-intercept is 5. This means that the line will pass through (0,5).
[tex]y=mx+\boxed{b}\\\\y=3x+\boxed{5}[/tex]
The correct option should be B.
Hope this helps.
If an angle has a measure of x radians, what is the measure of the angle in degrees?
 degrees
Write a function ff that determines the degree measure of an angle in terms of the radian measure of the angle, x.
f(x)=
Answer:
Step-by-step explanation:
2π radians = 360°
x radians · 360°/(2π radians) = (180x/π)°
f(x) = 180x/π
The measure of the angle in degrees would be (180x/π)° and the function would be f(x) = 180x/π which determines the degree measure of an angle in terms of the radian measure of the angle x.
What is a function?The function is defined as a mathematical expression that defines a relationship between one variable and another variable.
Given that an angle has a measure of x radians,
So the measure of the angle in degrees
Since 2π radians = 360°
Therefore x radians · 360°/(2π radians)
= (180x/π)°
A function f represents the degree measure of an angle in terms of the radian measure of the angle, x.
⇒ f(x) = 180x/π
Hence, the measure of the angle in degrees would be (180x/π)° and the function would be f(x) = 180x/π which determines the degree measure of an angle in terms of the radian measure of the angle x.

Answer:
1. 1900 children.
2. 600 adults.
Step-by-step explanation:
Let c represent the number children.
Let a represent the number of adult.
From the question given above, we were told that 2500 people entered the fair. This can be obtained as follow:
2500 = c + a ..... (1)
From the question given above, we were told that:
Cost per child = $ 2
Cost per adult = $ 4
Total amount collected = $ 6200
Thus, we can write the above as:
6200 = 2c + 4a .....(2)
Summary:
2500 = c + a ..... (1)
6200 = 2c + 4a .....(2)
1. Determination of the number of children that attended the fair.
From equation 1
2500 = c + a
Make a the subject by rearranging
a = 2500 – c ....... (3)
Substitute the value of 'a' in equation 3 into equation 2
6200 = 2c + 4a
a = 2500 – c
6200 = 2c + 4(2500 – c)
Clear bracket
6200 = 2c + 10000 – 4c
Collect like terms
6200 – 10000 = 2c – 4c
–3800 = –2c
Divide both side by –2
c = –3800 / –2
c = 1900
Thus, 1900 children attended the fair
2. Determination of the number of adults that attended the fair.
Substitute the value of c into equation 3.
a = 2500 – c
c = 1900
a = 2500 – 1900
a = 600
Thus, 600 adults attended the fair.
the formula C = 6p + 200 gives C , the total cost in dollars of hosting a birthday party for p guests at a local ice cream parlor .
A : solve the formula for p .
B : isabella can spend $350 for her birthday party . how many people can she invite ?
y = 2x + 4
and
y = 2x - 8
Solve the systems by substitution
Answer:
-x - y - z = -8 ........ (1a)
-4x + 4y +5z = 7 ..... (2a)
2x + 2x = 4 .......... (3a)
since (3a) a is an equation solely in x make x the subject of the equation
2 ( x + x) = 4
divide both sides by 2
(x + x) = 2
2x = 2
x = 1 ....... (3b)
substitute x in (3b) for x in (1a)
-(1) - y - z = -8
make y the subject of the equation
-y - z = -8 + 1
-y = -7 + z
y = 7 - z ..... (1b)
substitute y in (1b) for y in (2a) as well as the value of x ( x= 1)
-4(1)+ 4( 7 - z ) +5z = 7
- 4 + 28 - 4z + 5z = 7
-24 + z = 7
z = 7 + 24
z = 31
By using (1a) solve for y
-(1) - y - (31)= -8
-1 - y - 31 = -8
y = -1 - 31 + 8
y = -24
∴ the solutions of the system are x = 1 ; y = -24 ; z = 31
Hope this helps!!!!!!!

Urgent!!!! Solve 3∣∣x+2∣∣<12.
Graph the solutions on the number line.
Step-by-step explanation:
First, you have to solve the inequality of x :
| x + 2 | < 12
x + 2 < 12
x < 10
AND
- x - 2 < 12
- x < 14
x > - 14
Therefore, the values of x is -14 < x < 10 so you have to draw it on the number line.

Find the values of a, b and c
a =
b =
c =
Answer:
a = -3
b = 3
c = 4
Step-by-step explanation:
Let's do this the long way!
[tex]x = \frac{-3 \pm\sqrt{3^2 - 4 \times (-3) \times 4}}{2 \times (-3)}\\-6x = -3 \pm\sqrt{3^2 - 4 \times (-3) \times 4}\\-6x + 3 = \pm\sqrt{3^2 - 4 \times (-3) \times 4}\\(-6x + 3)^2 = 3^2 - 4 \times (-3) \times 4\\36x^2 - 36x + 9 = 9 + 48\\36x^2 - 36x - 48 = 0\\3x^2 - 3x - 4 = 0[/tex]
So a = 3, b = -3, and c = -4
HOWEVER:
When you look at the terms in the solution originally given, the are all the negatives of what we see here. That however makes sense, as we can simply multiply both sides of the equation to get the results they used:
[tex]3x^2 - 3x - 4 = 0\\-1(3x^2 - 3x - 4) = -1(0)\\-3x^2 + 3x + 4 = 0[/tex]

Four sisters are all 2 years apart in age. The
total of their ages is equal to 36 years. How
old is the youngest sister
The equation that represents the age of the youngest sister is 4x + 12 = 36. Then the age of youngest sister will be 6 years old.
What is Algebra?The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
The four sisters are all 2 years apart in age. The total of their ages is equal to 36 years.
Let x be the age of the youngest sister. Then the age of other sister will be x + 2, x + 4, and x + 6. Then the equation is given as,
x + x + 2 + x + 4 + x + 6 = 36
4x + 12 = 36
4x = 36 - 12
4x = 24
x = 24 / 4
x = 6
The equation that represents the age of the youngest sister is 4x + 12 = 36. Then the age of youngest sister will be 6 years old.
