Answer:
y=0.8*x -19
Step-by-step explanation:
y-5=4/5(x-30)
5*(y-5)=5*(4/5(x-30))
5y-25=4x-120
5y=4x-120+25
5y=4x-95
y=(4/5)*x -19
y=0.8*x -19
find the value of x in the figure
Answer:
the value of y = 160
Step-by-step explanation:
exterior angle=sum of two opposite interior angle
y=(180-50)+30
y=160

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.
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].

Dr. Bethea has 11 pieces of fruit to give out to his 3 children. He wants to give each child the same number of pieces of fruit. How many pieces of fruit will be left over after he gives them out?
Answer:
2
Step-by-step explanation:
Since in this case they aren't going to cut up the fruit, you find how many times 3 will go into 11 evenly. 3x3=9 which is the largest multiple of 3 that will fit into 11. 11 pieces subtract 9 pieces given to children = 2 pieces left. Hopefully this helps.

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!
Modular arithmetic
Pls a little explaine it
Step-by-step explanation:
(72)¹⁴³ ≡ x (mod 7)
Since 72 ≡ 2 (mod 7),
72³ ≡ 2³ (mod 7) ≡ 1 (mod 7).
Therefore (72)¹⁴³ = (72³)⁴⁷ * (72²)
≡ 1⁴⁷ * 4 (mod 7) ≡ 4 (mod 7).

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

Answer:
The number is 42
Step-by-step explanation:
Let the number be [tex]x[/tex]
According to the problem,

Violet owns a food truck that sells tacos and burritos. She only has enough supplies to make 120 tacos or burritos. She sells each taco for $3.25 and each burrito for $7.50. Violet must sell no less than $570 worth of tacos and burritos each day. Also, she must sell a minimum of 30 tacos. If x represents the number of tacos sold and y represents the number of burritos sold, write and solve a system of inequalities graphically and determine one possible solution.
Answer: y>~ 570-3.25x/ 7.50
y>~ -13/30x
x>~30
Step-by-step explanation:
The solution to the inequality in the graph has been shown.
What is inequality?Inequality can be defined as the relation of the equation containing the symbol of ( ≤, ≥, <, >) instead of the equal sign in an equation.
Here,
According to the question,
x + y ≤ 120
x = 120 - y,
x ≥ 30
Or
3.25x+ 7.50 ≥570
Thus, the solution to the inequality in the graph has been shown.

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.

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:

Find the missing angle B
Answer:
The missing angle B:
m∠B = 25⁰Step-by-step explanation:
Given the angles
A = 100⁰
C = 55⁰
B = ?
We know that the sum of the angles of triangles is 180⁰.
so
A + B + C = 180⁰
100⁰ + B + 55⁰ = 180⁰
B = 180⁰ - 55⁰ - 100⁰
B = 25⁰
Therefore, the missing angle B:
m∠B = 25⁰

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.

Answer:
is a mathematics problem and is so easy and square and triangle and rectangle and circle formulas
Step-by-step explanation:
√(a - r) + m = y
√(a - r) = y - m
(a - r) = (y - m)²
a = (y - m)² + r
