Answer:
3x - y = 10
Step-by-step explanation:
y-5 = 3(x-5)
y - 5 = 3x-15
-3x+y= -10
3x - y = 10

The area of the floor of a cubical room is 49
[tex] {m}^{2} [/tex]
Find the area of 4 walls
Step-by-step explanation:
Since its a cube, Area of Floor = Area of Wall (Area of Square)
Area of 1 wall =
[tex]49 {m}^{2} [/tex]
Area of 4 walls =
[tex]49 \times 4 \\ = 196 {m}^{2} [/tex]
A cubical is a 3D square where all the sides are the same length.
The area of the floor is 49 square metered.
Since all sides are equal the area of the walls would also be 49 square meters each.
The area of the 4 walls would be 49 x 4 = 196 square meters.
Please help! What is the Area of the Triangle?
Answer and explanation please! <3
Answer:
area of a triangle is equals to sum of all side
Answer:
5√5
Step-by-step explanation:
the area of the triangle is, "base len x height"
the base in here is √1^2 + 2^2 = √5
its height is √4^2 + 3^2 = 5
so the area is √5 x 5 = 5√5

Answer:
p = 132 - 30d
Step-by-step explanation:
Here, we can plug in x = 6 into the equation provided at the end of the problem.
p = 6[25 - (3 +5d)]
p = 150 - 18 - 30d
p = 132 - 30d

13. Find 3 fractions that are equivalent to 2/3. Explain how you found your answers
Answer:
[tex]\frac{4}{6} =\frac{6}{9}= \frac{8}{12}[/tex]
Step-by-step explanation:
I'm assuming this is asking for 3 separate fractions that are each equal to 2/3
Remember, multiplying the top and bottom of a fraction by a number will not change the fraction.
[tex]\frac{2}{3} *\frac{2}{2} =\frac{4}{6}[/tex]
[tex]\frac{2}{3} *\frac{3}{3} =\frac{6}{9}[/tex]
[tex]\frac{2}{3} *\frac{4}{4} =\frac{8}{12}[/tex]
These three fractions are all equal to 2/3
A line has a slope of 1/2 and passes through the point (6,2).
a) Write the equation of this line in point-slope form
(b) What is the y-intercept of this line?
Answer:
a) y-2=1/2(x-6) b) The y-intercept of this line is -1.
Step-by-step explanation:
y-y1=m(x-x1)
y-2=1/2(x-6)
------------------
y=1/2x-6/2+2
y=1/2x-3+2
y=1/2x-1
y=mx+b where m=slope and b=y-intercept.
Which of the following numbers would be to
the left of the number -1 on a number line?
8
4
0
-0.5
-4
Answer:
-4
Step-by-step explanation:
Numbers decrease on a number line as you go left. So, to find a number to the left of -1, you need to find a number that is smaller. Since negative numbers decrease in value as they get further from 0, -4 must be smaller than -1. All other values listed will be to the right of -1.
You are given two functions f(x) and g(x). How has the graph of g(x) changed from that of f(x)?

Find the length of the arc, s, on a circle of radius r intercepted by a central angle theta. Express the arc length in terms of pi. Then round your answer to two decimal places. Radius, r = 10 inches; Central angle, theta = 45 degrees
Answer:
arc = 2.5π
Step-by-step explanation:
the circumference of the circle is:
2(10)(π) = 20π
45°/360° = 1/8
(1/8)20π = 2.5π

A construction crew is lengthening a road that originally measured 44 miles. The crew is adding 1 mile to the road each day. The length, L (in miles), after d days of construction is given by the following function.
L(d)= 44+d
What is the length of the road after 35 days?
Answer:
The length of the road after 35 days is of 79 miles.
Step-by-step explanation:
The length of the road, after d days, is given by:
[tex]L(d) = 44 + d[/tex]
What is the length of the road after 35 days?
This is l when d = 35. So
[tex]L(35) = 44 + 35 = 79[/tex]
The length of the road after 35 days is of 79 miles.

Find the value of x
Answer:
x=80
Step-by-step explanation:
(x+30)=110 because they are vertically opposite angles.
x+30=110
x=110-30
x=80
Answer:
x = 80 degrees
Step-by-step explanation:
x + 30 = 110
- 30 = -30
x = 80 degrees
Find the midpoint of the segment with the following endpoint (9,2) and (5,5)
Answer:
(7, 3.5)
Step-by-step explanation:
find the distances between the x and y
9 and 5 are 4 apart, and 2 and 5 are 3 apart
divide those distances by 2
4/2 = 2, 3/2 = 1.5
add those distances to the smaller of the x and y
5 + 2 = 7, 2 + 1.5 = 3.5
those two numbers are the midpoint (7, 3.5)
