write the slop intercept form of the equations below.
1. slope= 1/4,y intercept = 4
2. y-5=-4(x+1)
Answers
2 is y=x+1
Step-by-step explanation:
Given :-
1. slope= 1/4,y intercept = 42. y-5=-4(x+1)And we need to find the slope intercept form of the line . The slope intercept form of a line is y = mx + c , where m is the slope and c is the y intercept. Substitute respective values ,
Solution 1 :-
[tex]:\implies[/tex] y = mx + c
[tex]:\implies[/tex] y = 1/4 x + 4
[tex]:\implies[/tex] 4y = x + 16
[tex]:\implies[/tex] x - 4y + 16 = 0
Solution 2 :-
[tex]:\implies[/tex] y - 5 = -4( x +1)
[tex]:\implies[/tex] y -5 = -4x -4
[tex]:\implies[/tex] y = -4x +1
What is the slope of the line?
Answers
To find the slope, one will need to use the expression Δy/Δx (y final - y initial)/(x final - x initial)
For this problem, that equals 1/3
Now we will use the point slope form
(y - y initial) = m (x - x initial):
y + 1 = 1/3 (x - 2)
y = 1/3x - 5/3

Solve the system of linear equations by substitution 12x+y=−4 y=2x+16
Answers
Answer:
Your solution is (-10/7, 92/7)
Step-by-step explanation:
12x + y = -4
y = 2x + 16
To use substitution, we want to plug one variable's equation into the other equation.
We can see that y is already solved for us. Plug y into the first equation.
12x + y = -4
12x + (2x + 16) = -4
Combine like terms.
14x + 16 = -4
Subtract 16 from both sides.
14x = -20
Divide both sides by 14.
x = -20/14
x = -10/7
Now that we know x, we will plug it into one of the other equations.
y = 2x + 16
y = 2(-10/7) + 16
Multiply.
y = -20/7 + 16
Add.
y = -20/7 + 112/7
y = 92/7
Your solution is (-10/7, 92/7)

YS = 2/3 × ( YV ) *.&.* SV = 1/3 × ( YV )
_____________________________
YS = 2/3 × ( YV )
4x + 14 = 2/3 × ( YV )
Multiply both sides by 3/2
( 4x + 14 ) × 3/2 = ( YV ) × 2/3 × 3/2
YV = 6x + 21 ( ☆ )
¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥
SV = 1/3 × ( YV )
1 + 3x = 1/3 × ( YV )
Multiply both sides by 3
( 1 + 3x ) × 3 = ( YV ) × 1/3 × 3
YV = 9x + 3 ( ♡ )
_____________________________
YV = YV
( ☆ ) = ( ♡ )
6x + 21 = 9x + 3
Subtract both sides 3
6x + 21 - 3 = 9x + 3 - 3
6x + 18 = 9x
Subtract both sides 6x
6x - 6x + 18 = 9x - 6x
18 = 3x
Divide both sides by 3
18 ÷ 3 = 3x ÷ 3
x = 6

Natalie is having a birthday party and it's time to cut
the cake.
Unfortunately she doesn't know how far she needs to
cut from the center to the edge of the cake.
She remembered the baker told her that the
circumference is 46 inches.
How far should Natalie cut?
**NO spaces
**Include units
**Round to the nearest hundredths
Answers
Answer:
7.32 inches
Step-by-step explanation:
The circumference of the circle is 46 inches, and you just have to find the radius... you do the 2xpixr=C backwards. So 2xpixr=46 simplify the expression; 6.28xr=46 then divide... r=46/6.28... Which rounds to 7.32 inches as the radius.
(And yes you are finding the radius if you are finding a line from the middle of the circle to an edge)

Abdullah is kicking a soccer ball into the air. The path of the soccer ball can be modeled by a quadratic equation where the point (6, 12) represents the vertex and the x-axis represents the ground. Which equation could represent the location of the soccer ball when it hits the ground? A 0=−(x−6)2+12 B 0=−(x+6)2−12 C 0=−(x−6)(x−12) D 0=−(x+6)(x+12)
Answers
9514 1404 393
Answer:
A. 0 = −(x−6)^2+12
Step-by-step explanation:
The vertex form of a quadratic equation is ...
y = a(x -h)² +k . . . . . . for vertex (h, k) and scale factor 'a'
When the given vertex (h, k) = (6, 12) is used, we find the form of the equation to be ...
y = a(x -6)² +12
The ball will be on the ground when y = 0. Here, the vertical scale factor 'a' is -1, so the equation representing the ball being on the ground is ...
0 = -(x -6)² +12 . . . . . . matches choice A
