The slope-intercept form of a line:
m - slope
b - y-intercept
Convert 2x + 3y = -6 to the slope-intercet form:
<em>subtract 2x from both sides</em>
<em>divide both sides by 3</em>
Let 
and 
We have 
Therefore
We have the equation of a line:
Put the coordinates of the point (0, 0) to the equation:
Answer: 
Step-by-step explanation:
w = 2
x = 5
y = 8
z = 3
= x² + 2y ÷ w + 3z
= (5)² + 2(8) ÷ (2) + 3(3)
= 25 + 16 ÷ 2 + 9
= 25 + 8 + 9
= 42
Answer:
1.- 140 in²
2.- 2.25 in²
3.- 43.25 in²
4.- 7.5 in²
5. 349.75 in²
Step-by-step explanation:
4 congruent triangles mean 4 triangles same measurement
area 1 triangle=(B*H)/2=(10*7)/2=35in²
for area of the roof are 4 by area 1 triangle=4*35=140 in²
2.- area hole. Hole is a square so area Is side by side
area=1.5*1.5=2.25
3.- area front except the hole. As the side of front is isosceles trapezoide which it’s area is (B1+B2)H/2 where B1=8 in and B2=5 in and H=7 in
so arera with hole=(8+5)*7/2=45.5 in²
Answer:
Step-by-step explanation:
2x - 5y = 10
2(-3.5) - 5y = 10
-7 - 5y = 10
+7 +7
-5y = 17
-5 -5
y = -3.4
The value of y is equal to A. -3.4.
To find this answer, we need to multiply 3.57 by 12.
Therefore, 12 planks will cost $42.84.
