Answer:
y = -1
Step-by-step explanation:
Given x = 30 , y = 14 -0.5x
Find y
let (x = 30) fill in y
y = 14 - 0.5(30)
y = 14 - 15
Thus , y = -1what's the value of

X = 15
PQ = 26
Answer:
x = 31.4
PQ = 58.8
Step-by-step explanation:
Set up a proportion:
SQ/QP = ST/PR
Substitute in the values they give you:
[tex]\frac{x-9}{x-9+x+5} = \frac{8}{21}[/tex]
[tex]\frac{x - 9}{2x - 4} = \frac{8}{21}[/tex]
[tex]21x - 189 = 16x - 32\\5x = 157\\x = 31.4[/tex]
This means that PQ = 2x - 4 = 2(31.4) - 4 = 62.8-4 = 58.8
Answer:
x = 15, PQ = 26
Step-by-step explanation:
x+13/9 = 21/x-9
x^2+4x−117=168
x^2+4x−285=0
(x−15)(x+19)=0
x=15
it cannot be a negative number so x cannot be -19
PQ= x+13
15+13=26

If [tex]ac^3+bx^2+c[/tex] is divided by (x-3) then the remainder is:
Silly answers will not be tolerated
Answer:
27a + 9b + c is reminder
Step-by-step explanation:
Remainder theorem says that when p(x) is divided by (x – a) the remainder is given
by p(a)
Let p(x) = ax³ + bx²+ c
P(x) when divided by (x – 3)
Using Remainder theorem, we have
Remainder = p(3) = a(3³) + b(3²) +c
= 27a + 9b + c

Step-by-step explanation:
A circle with a radius of r units is dilated by a scale factor of 7 to create a new circle. Which statement about the area of the new circle is true?
A. The area of the new circle is 7 times the area of the original circle.
B. The area of the new circle is 14 times the area of the original circle.
C. The area of the new circle is 49 times the area of the original circle.
D. The area of the new circle is squared root 7 times the area of the original circle.
Answer:
A
Step-by-step explanation:
The scale factor can be defined as the ratio of new dimension of an object after scaling to the original dimension. The are of the new circle is 49 times the area of the original circle. The correct answer is option C.
What is Scaling factor ?Scaling factor is a conversion factor used to change the size of a figure without changing its shape. When the size of a figure is increased, it called scaled up and when it decreases it is called as scaled down.
Given that, Scale factor of circle = 7.
Since, the scale factor of a circle is the ratio of new radius to original radius.
The new radius of circle can be written as,
r' = 7r
Thus, the area of new circle is π × (r')^2= π × (49r^2).
Hence, the area of new circle is 49 times the original circle.

If Rihanna deposite 1500 rupees in the school fund at 9 p.C.P.A for 2 years, what is the total amount she will get?
Answer: 1770 rupees
Step-by-step explanation:
To solve this, we first calculate the simple interest which will be:
= (P × R × T) / 100
= (1500 × 9% × 2) / 100
= (1500 × 0.09 × 2) / 100
= 270
The total amount tha she'll get will be:
= 1500 + 270
= 1770 rupees

log Subscript 3 (2x-7)= 4
Answer:
x = 44
Step-by-step explanation:
You can rewrite logarithm equations like so:
[tex]log_{b}(x) = y\\\\x = b^y[/tex]
A way to remember this is the base in the logarithm is also the base in the exponent - then remember this base b is to the power of what's on the other side - and all this is equal to whatever's in the parentheses.
In this case,
[tex]log_3(2x-7) = 4\\2x - 7 = 3^4\\x = (3^4 + 7)/2 = 44[/tex]

9.9, 10.8, 10.8, 6.2, 10.8, 7.2
Answer:
The mean of the data set is 9.3 rounded to the nearest tenth
Step-by-step explanation:
First you add them all together: 9.9 + 10.8 + 10.8 + 6.2 + 10.8 + 7.2 = 55.7
Then you divide it by how many numbers there are which is 6 in this situation:
55.7 ÷ 6 = 9.28333333333. but if we round it to the nearest tenth we get 9.3
So the answer is 9.3

A bag of skittles contains only red, yellow, and green colors. The respective ratios are 1:3:5 for those three colors. If there are a total of 36 skittles in the bag, how many of each skittles red, yellow, and green are in the bag?
Answer:
Red skittles = 4 skittles
Yellow skittles = 12 skittles
Green skittles = 20 skittles
Step-by-step explanation:
A bag of skittles contains only red, yellow, and green colors.
The respective ratios are 1:3:5 for those three colors.
We have
red: yellow: green
1:3:5
The sum of the proportion = 1 + 3+ 5 = 9
If there are a total of 36 skittles in the bag, how many of each skittles red, yellow, and green are in the bag?
Hence,
Number of red skittles is calculated as:
1/9 × 36 skittles
= 4 skittles
Number of yellow skittles is calculated as:
3/9 × 36 skittles
= 12 skittles
Number of green skittles is calculated as:
5/9 × 36 skittles
= 20 skittles
Therefore, the number of
Red skittles = 4 skittles
Yellow skittles = 12 skittles
Green skittles = 20 skittles

The expression represents the distance in feet an object falls after seconds. The object is dropped from a height of 906 feet.
What is the height in feet of the object 2 seconds after it is dropped?
Write an expression representing the height of the object in feet seconds after it is dropped.
Answer:
[tex]842\ \text{ft}[/tex]
[tex]y(t)=906-16t^2[/tex]
Step-by-step explanation:
Let [tex]y[/tex] be the height the object from the ground.
[tex]s[/tex] be the initial height of the object = 906 ft
[tex]u[/tex] = Initial velocity = 0
[tex]g[/tex] = Acceleration due to gravity = [tex]32\ \text{ft/s}^2[/tex]
[tex]t[/tex] = Time
The expression would be
[tex]y(t)=s-ut-\dfrac{1}{2}gt^2\\\Rightarrow y(t)=906-16t^2[/tex]
The required expression is [tex]y(t)=906-16t^2[/tex]
At [tex]t=2\ \text{s}[/tex]
[tex]y(2)=906-16\times 2^2\\\Rightarrow y(2)=842\ \text{ft}[/tex]
The height of the object after 2 seconds of falling is [tex]842\ \text{ft}[/tex].

The equation of a line in slope- intercept form is
y = mx + c
Given
y - 3 = - 4(x + 2) ← distribute
y - 3 = - 4x - 8 ( add 3 to both sides )
y = - 4x - 5 ← in slope- intercept form
(b)
The equation of a line in standard form is
Ax + By = C ( A is a positive integer and B, C are integers )
From the slope- intercept form
y = - 4x - 5 ( add 4x to both sides )
4x + y = - 5 ← in standard form
