Answer:
x = 28, y = 23
Step-by-step explanation:
5y - 4 and 3y are alternate exterior angles and are supplementary, thus
5y - 4 + 3y = 180
8y - 4 = 180 ( add 4 to both sides )
8y = 184 ( divide both sides by 8 )
y = 23
Thus
3y = 3 × 23 = 69
2x + 13 and 3y are corresponding angles and congruent, thus
2x + 13 = 69 ( subtract 13 from both sides )
2x = 56 ( divide both sides by 2 )
x = 28
Answer:Y= -1/2x+7
Step-by-step explanation:
Write an equation of the line that has slope -1/2 and passes through the point (-4,5)
Y=mx+b
Y= 5
X=-4
M= -1/2
5=-1/2(4)+b
5=-2+b
5+2=b
7=b
Y= -1/2x+7
Wow, lots of points, easy qeustion and nobody anwering
ok so
basically solve for y
6x+4y=700
minus 6x from both sides
4y=-6x+700
divide both sides by 4
y=-3/2x+175
ok so
y=mx+b
m=slope
b=yintercept or where the line crosses the y axis
so
y=-3/2x+175
yintercept is 175 so go 175 units up on teh y axis and put a point there
slope is -3/2
slope=rise/run
go 3 units down and 2 units to the right from that first point you ploted
that is new point
connect the 2 points to get graph, or input a value for x and get a value for y to get a point
basically just find 2 differn points and connect them to graph
I have attached graph
Answer:
The arrow can be broken into a rectangle and a triangle.
And the area of the arrow is 22 ft^2
Step-by-step explanation:
Area of the rectangle:
length • width = 7 • 2 = 14 ft^2
Area of the triangle:
(base • height) / 2
You must add 1 + 2 + 1 in order to get the base which is 4
And to get the height, you must do 11 - 7 = 4 (height)
(4 • 4) / 2 = 8 ft^2
Add both areas together to get the area of the arrow:
14 ft^2 + 8 ft^2 = 22 ft^2
Hope this helps!
