Answer:
y=3/4x
Step-by-step explanation:
y-y1=m(x-x1)
y-(-3)=3/4(x-(-4))
y+3=3/4(x+4)
y=3/4x+12/4-3
y=3/4x+3-3
y=3/4x
Para encher 2/5 de uma piscina são necessários 60.000 litros de água. Qual é a capacidade dessa piscina?
Answer:
A capacidade dessa piscina é de 150.000 litros de água.
Step-by-step explanation:
A capacidade da piscina é de x.
Para encher 2/5 de uma piscina são necessários 60.000 litros de água.
Isto implica que:
[tex]\frac{2x}{5} = 60000[/tex]
[tex]2x = 60000*5[/tex]
[tex]x = \frac{60000*5}{2}[/tex]
[tex]x = 150000[/tex]
A capacidade dessa piscina é de 150.000 litros de água.
The sum of -3 times a number and 0.3 is at most 6.3. What are all the possible
values of the number?
Answer:
Step-by-step explanation:
Lets write an equation for this :)
So, the sum of -3 times a number and 0.3
This would be : -3x +0.3
Is at most, 6.3
so, it is equal to, or less than 6.3
-3x +0.3 < 6.3
Now lets solve!
x> -2
the number is greater than or equal to -2

A ladder leans against the side of a house. The angle of elevation of the ladder is 62 degrees and the top of the ladder is 14 ft above the ground. Find the distance from the bottom of the ladder to the side of the house. Round your answer to the nearest tenth.
Answer:
7.4 feets
Step-by-step explanation:
Distance from bottom of ladder to side of the house = d
θ = 62 ; height, h = 14
Using trigonometry :
Tan θ = opposite / Adjacent
Opposite = height ; adjacent = d
Tan 62° = 14 / d
1.8807264 * h = 14
d = 14 / 1.8807264
d = 7.44

Step-by-step explanation:
find the value of triangle.
Answer:
8
Step-by-step explanation:
[tex]\frac{8}{10}[/tex] = Δ / 10
Multiply both the sides by 10 to remove the denominator, 10 in the right of the equation.
[tex]\frac{8}{10}[/tex] × 10 = Δ / 10 × 10
Δ = [tex]\frac{8}{10}[/tex] × 10
The '10' can be cut off.
Δ = 8
What is the SUM of the INTERIOR angles in the figure
9514 1404 393
Answer:
sum of interior angles: 720°x = 97.5Step-by-step explanation:
The sum of interior angles of a hexagon is ...
180°(n -2) = 180°(6 -2) = 720°
__
The sum of the angles shown is ...
4x +330 = 720
x = 390/4 = 97.5 . . . . . . . . subtract 330 and divide by 4
__
The angle measures CW from lower left are 90°, 150°, 145°, 137.5°, 80°, 117.5°.

if you apply the changes below to the linear parent function, f(x) = x, what is the equation of the new function?
Given:
The linear parent function is
[tex]f(x)=x[/tex]
To find:
The new function after vertical stretch by a factor of 4 and flip over the x-axis.
Solution:
The transformation is defined as
[tex]g(x)=kf(x)[/tex] .... (i)
Where, k is either vertical stretch or vertical compression.
If 0<|k|<1, then the graph compressed vertically by factor |k| and if |k|>1, then the graph stretch vertically by factor |k|.
If k<0, then the graph flip over the x-axis.
It is given that the graph of f(x) vertically stretch by a factor of 4. So, |k|=4.
The graph flip over the x-axis. So, the value of k must be negative, i.e., k=4.
Using (i), we get
[tex]g(x)=-4f(x)[/tex]
We have, [tex]f(x)=x[/tex]
[tex]g(x)=-4x[/tex]
Therefore, the correct option is B.
Answer: g(x)= -4x

help! Solve for the value of k
Answer:
k = 42
Step-by-step explanation:
These are complementary angles so they add to 90°
90 = 47 + (k + 1)
90 - 47 = k + 1
43 = k + 1
k = 42

Answer:
y int (0, -45) x int (-10, 0)
Answer:
Step-by-step explanation:
When x = 0, y = -45, so the vertical intercept is (0, -45).
When y = 0, x = -10, so the horizontal intercept is (-10, 0).
The triangle-shaped entrance to the cavern is 2 1/2 feet tall and 4 feet wide. What is the area of the entrance?
Answer:
5 feet²
Step-by-step explanation:
The area of entrance = area of triangle
Height, h = 2 1/2 feets
Width, w = 4 feets
The Area of a triangle is given as :
1/2 * base * height
Base = width = 4 feets
Area of entrance = 0.5 * 4 * 2.5
Area of entrance = 5 feet²
Hence, the area of the entrance is 5 feet square.
