I GIVEEEEE BRAINLILSTTTTT
Answer:
side of black is 7
side of green is 14
Dilation scale factor is 2
hope this helps :)
please mark branliest
Step-by-step explanation:
Answer:
2
Step-by-step explanation:
To find the scale factor of a dilation, we first have to find two corresponding sides. For example, the top edge of the black shape corresponds with the top edge of the green shape. The length on the black shape measures 7 units and the length on the green shape measures 14 units.
Now, we divide the length taken from the figure by the length taken from the original shape.
14/7=2
Therefore, the scale factor of the dilation is 2.
I hope this helps!

If Y varies directly with X,
find y when X =24 if y =5
when X = 30.
Answer:
We get Y=4 when X =24
Step-by-step explanation:
If Y varies directly with X, find Y when X=24, if Y = 5 when X= 30.
We are given If Y varies directly with X, we can write:
[tex]Y\:\alpha\: X\\Y=kX[/tex]
Where k is constant of proportionality
We need to find Y when X=24, first we need to find k, the constant of proportionality.
Now, we are given: If Y = 5 when X= 30.
We can find value of k
[tex]Y=kX\\5=k(30)\\k=\frac{5}{30}\\k=\frac{1}{6}[/tex]
So, k=1/6
Now, we will find Y when X = 24
and k=1/6
[tex]Y=kX\\Y=\frac{1}{6}(24)\\Y=4[/tex]
So, Y=4 when X =24.
find the slope of the line? (6,-2) and (2,0)
Answer:
-1/2
Step-by-step explanation:
(x1,y1)=(6,-2) and (x2,y2)=(2,0)
now using slope formula
=(y2-y1)/(x2-x1)
=(0+2)/(0-6)
=-(1/2)

The picture shows us that the shape is a square.
To find the area of a square you would use the formula s^2
s= 8ft
8ft^2 = 64ft^2
with area you would need to use the unit ft^2
I hope this helps!!!
Answer: DDDDDDD
Step-by-step explanation: The formula is width x height, so we can use the expression 8 x 8 assuming this is perfectly square. 8 x 8 is 64 square units

Convert the following equation from standard form to slope-intercept form.
x +y = -3
Answer:
y=-x-3
Step-by-step explanation:
Slope intercept form is y=, and so we had to get the x to the other side. To do that you would subtract x from each side and then you get your answer.

What’s the domain and range of this graph?
Given:
The graph of a downward parabola.
To find:
The domain and range of the graph.
Solution:
Domain is the set of x-values or input values and range is the set of y-values or output values.
The graph represents a downward parabola and domain of a downward parabola is always the set of real numbers because they are defined for all real values of x.
Domain = R
Domain = (-∞,∞)
The maximum point of a downward parabola is the vertex. The range of the downward parabola is always the set of all real number which are less than or equal to the y-coordinate of the vertex.
From the graph it is clear that the vertex of the parabola is at point (5,-4). So, value of function cannot be greater than -4.
Range = All real numbers less than or equal to -4.
Range = (-∞,-4]
Therefore, the domain of the graph is (-∞,∞) and the range of the graph is (-∞,-4].
find the coordinates of the foot of the perpendicular from (6,8) the line through(1,5) and (9,3)
Answer:
plz follow and thanks me
Step-by-step explanation:
Let (a,b) be the coordinates of the foot of the perpendicular from the point (−1,3) to the line 3x−4y−16=0
Slope of the line joining (−1,3) and (a,b), is m

=
a+1
b−3
Slope of the line 3x−4y−16=0 or y=

Since these two lines are perpendicular,m

∴{

⇒

⇒3b−9=4a−4
⇒4a+3b=5...(1)
Point(a,b) lies on line 3x−4y=16
∴3a−4b=16....(2)
On solving equation (1) and (2) we obtain
a=

Eduardo is solving this number riddle by using guess and check.
Thirteen less than my number is twenty-nine. What is my number?
This is a
problem.
Eduardo must find
.
To use guess and check, Eduardo can
13 from
.
Thirteen less than
is twenty-nine.
Answer:
subtraction, n - 13 is 29, subtract, different numbers, 42.
Answer:
The number is 42
Step-by-step explanation:
Let the number be [tex]x[/tex]
According to the problem,
[tex]x - 13 = 29[/tex]
⇒ [tex]x = 29 + 13[/tex]
⇒ [tex]x = 42[/tex]
Hence, the number is 42.

Find the perimeter of a rectangle whose length is 4 cm greater than its height, and whose area is 60 cm².
Answer:
Perimeter of the rectangle = 32 cm
Step-by-step explanation:
Explanation:-
Let the height of the rectangle = 'x' cm
Thus the length of the rectangle = x + 4 cm
Perimeter of the rectangle = 2 ( length + height )
Area of the rectangle = length X height
Given area of the rectangle = 60 cm²
( length X height ) = 60
( x + 4) x =60
x² + 4 x - 60 =0
x² + 10 x- 6 x - 60 =0
x ( x+10) - 6 ( x + 10 ) =0
(x+10) ( x -6 ) = 0
x = -10 and x =6
we can choose x =6
The height of the rectangle(H) = 'x' = 6 cm
The length of the rectangle (L)= 6 + 4 = 10cm
Perimeter of the rectangle = 2 ( length + height )
= 2 ( 10 + 6 )
= 32 cm
∴ Perimeter of the rectangle = 32 cm
Answer:
32 cm
Step-by-step explanation:
height = x
length = x+4
x(x+4)=60
x^2 +4x=60
make it into quadratic formula
x^2 + 4x - 60 =0
a=1
b=-4
c=-60
4^2-4*1*(-66)
discriminant equals to 256
square root of 256 equals to 16
x=-4+16/2 = 6
x=-4-16/2 = -10
we will use 6
length is x+4 so 6+4 = 10
width is x = 6
10 plus 10 = 20
6 plus 6= 12
20+12=32 cm
What expression is equivalent to
4/9(2n - 3)
Answer:8/9 n- 12/9
Step-by-step explanation: You do distributive property.Which is 4/9 times 2 n but you make both 4/9 and 2 to a fraction which is 4/9 times 2/1 which gives you 8/9 .Next you do 4/9 times 3 but make to a fraction both which is 4/9 times 3/1 which gives you 12/9 .Next you take the 8/9 n and 12/9 and you subtract it .Which gives you 8/9 n- 12/9 as your expression.

Write the final equation using the slope-intercept form perpendicular to 3y = x − 4 and passes through the point (−2, 1)
Answer:
y=-3x-5
Step-by-step explanation:
given equation:
3y=x-4
slope intercept form is y=mx+b
(m is the slope, b is the y intercept)
divide by 3
y=1/3x-4/3
perpendicular lines have slopes that are negative and reciprocal. If you multiply them together, the result is -1.
so to find the slope of the perpendicular line, use this equation:
1/3m=-1
multiply by 3
m=-3
the slope of the new line is -3.
here is our equation so far:
y=-3x+b
now, we need to find b.
Since the equation of the line passes through the point (-2,1) we can substitute that into the equation to find b
1=-3(-2)+b
multiply
1=6+b
subtract 6
-5=b
so the line is y=-3x-5
Hope this helps!
