Answer:
x=62
Step-by-step explanation:
(x+1)+ x+55=180
-55 -55 (take away the 55)
(x+1)+ x= 125 (take out of parenthesis)
x+1+ x= 125
2x+ 1= 125 (add the two x's together)
-1 -1 (take away the one)
2x= 124 (divide by 2)
2
x=62

What is the suface area of a rectangular prism that measures 2cm × 5cm × 8cm?
Answer: 132 hope that helps
Step-by-step explanation
Fastest way to do it A=2(wl+hl+hw)=2·(5·2+8·2+8·5)=132
Answer:
132 [tex]cm^{2}[/tex]
Step-by-step explanation:
A rectangular prism has 6 sides in total. We need to find the area of each side and add the areas together to find the total surface area.
Each side has an opposite that's parallel and on the opposite side of the prism, so there are 3 different sides whose areas are to be multiplied by 2.
First: let this side be SIDE A: 5 x 8 = 40 [tex]cm^{2}[/tex]
Second, let this side be SIDE B: 8 x 2 = 16 [tex]cm^{2}[/tex]
And thirdly, let this side be SIDE C: 2 x 5 = 10 [tex]cm^{2}[/tex]
These are the areas of 3 of the the sides of the prism. The other 3 are identical.
Now to find the Total SA, we add all of them together,
SA = 2 x (SIDE A) + 2 x (SIDE B) + 2 x (SIDE C).
= (2 x 40) + (2 x 16) + (2 x 10)
= 80 + 32 + 20
SA = 132 [tex]cm^{2}[/tex]

Find the area of the composite shape.
Answer:
For the one on the far left its 104 m2
Step-by-step explanation:
u split the shape in a square and rectangle
them u fin the area of the square by multiplying both sides. (8*8)
then u find the area of the rectangle by using the formula
2*(16+4)
when u find both areas u count them up and it'll become 104 m squared

evaluate the function h(x) = |-2x|-9 for the given values of x a) h(4)=. b) h(-5)=. c) h(0) =
Answer:
h(4) = -1 ; h(-5) = 1 h(0) = -9
Step-by-step explanation:
a) h(x) = |-2x| - 9 Substitute x = 4
h(4) = | -2 · 4| - 9
h(x) = | -8| - 9
h(4) = 8 - 9
h(4) = -1
b) h(x) = |-2x| - 9 Substitute x = -5
h(-5) = |-2 · -5| - 9
h(-5) = |-10| - 9
h(-5) = 10 - 9
h(-5) = 1
c) h(x) = |-2x| - 9 Substitute x = 0
h(0) = |-2 · 0| - 9
h(0) = |0| - 9
h(0) = 0 - 9
h(0) = -9
What is an equation of the line that passes through the points (6,-3) and (-6,-5)
Answer:
y = 6x - 4
Step-by-step explanation:
I drew a graph slope formula is (y2 - y1)/(x2 - x1) and if the line passes through a point that is not zero (in this case it does) we add or subtract that as the y-intercept. we recently passed this so I know it.
Slope-intercept form: (y = mx + b) y = 6x - 4
Standard form: (Ax + By = C) -6x + y = -4
Point-slope form: (y - y1 = m (x - x1)) (let's use the point (6, -3)) y + 3 = 6 (x - 6)
Tell me if I'm wrong :)
Answer:
Step-by-step explanation:
Bu using the formula of Two-Points form:
[tex]\frac{y-y_{1} }{y_{2}-y_{1} } =\frac{x-x_{1} }{x_{2}-x_{1} }[/tex]
Substitute the points in the above equation:
y+3/-5+3=x-6/-6-6
y+3/-2=x-6/-12
-12(y+3)=-2(x-6)
-12y-24=-2x+6
2x-12y-24-6=0
2x-12y-30=0
Or
x-6y-15=0

write the equation of the line that passes through the points (2 , -1) and has a slope of - 3
Answer:
y=-3x+5
Step-by-step explanation:
y=mx+b
m=slope or gradient (=-3)
y=-3x+b
Add your points
(2, -1)
-1=(-3 x 2)+b
-1= -6+b
-1+6=b
b=5
y=-3x+5
Answer:
[tex]\boxed {\boxed {\sf y= -3x+5}}[/tex]
Step-by-step explanation:
We are asked to find the equation of the line that passes through the point (2, -1) and has a slope of -3.
We are given a point and the slope, so we can use the point-slope formula.
[tex]y-y_1=m(x-x_1)[/tex]
In this formula, m is the slope and (x₁, y₁) is the point the line passes through.
The line has a slope of -3 and passes through (2, -1).
m= -3 x₁= 2 y₁= -1Substitute the values into the formula.
[tex]y--1= -3 (x-2)[/tex]
[tex]y+1= -3 (x-2)[/tex]
Distribute the -3 on the right side. Multiply each term inside the parentheses by -3.
[tex]y+1 = (-3*x) + (-3*-2)[/tex]
[tex]y+1=(-3x) + (6)[/tex]
[tex]y+1=-3x+6[/tex]
Subtract 1 from both sides of the equation to isolate the variable y.
[tex]y+1-1=-3x+6-1[/tex]
[tex]y=-3x +5[/tex]
The equation of the line is y= -3x+5.

The question is asking what is ∠ABD, you have to look at when A=0 on the projector, so if you follow along the 0° from A, when it reaches D, the project reads 100°
no guessing here,
you know 80° cannot be correct because this angel is obtuse and not acute
which means greater that 90°
y=-6/5x +4
y-= -1/5x -1
Answer: (5,-2)
Step-by-step explanation:
I'm assuming the equations are:
Y=-(6/5)x +4
y = -(1/5)x -1 [Note that I changed "y-" to just "y."]
We can solve this in one of two ways: Mathematically and Graphically.
Math:
y = -(1/5)x -1
6y = -(6/5)x -6
-(Y=-(6/5)x +4)
5y = -10
y = -2
y = -(1/5)x -1
-2 = -(1/5)x -1
-1 = -(1/5)x
5 = x
x = 5
The solution is (5,-2)
Graph:
See the attached graph. The lines intersect at (5,-2)
