The answer is 94sq inches :D
First distribute -3 to both x and -17
-3(x) = -3x
-3(-17) = 51
y - 5 = -3x + 51
isolate the y, add 5 to both sides
y - 5 (+5) = -3x + 51 (+5)
add all numbers with same variables together
y = -3x + 51 + 5
y = -3x + 56
inside the slope intercept form:
y = y
m = slope
x = x
b = intercept.
y = mx + b (using this equation, we can see that -3 = m)
-3 is slope, and is your answer
hope this helps
Answer:
y = - 3x - 7
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (- 3, 2) and (x₂, y₂ ) = (- 2, - 1)
m = = = - 3, thus
y = - 3x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (- 2, - 1), then
- 1 = 6 + c ⇒ c = - 1 - 6 = - 7
y = - 3x - 7 ← equation in slope- intercept form
Answer:
12+x=12+4=16
3x+y=3*4+7=12+7=19
4y-10=4*7-10=28-10=18
1/2xy=1/2*4*7=28/2=14
Step-by-step explanation:
Answer:
b
Step-by-step explanation:
-a-(a-b)
Distribute the negative sign to get -a+a+b
-a cancels out a, and you're left with b.
