Find the slope of the line passing through the 2 points (-7,8), (-4,3
Answer:
5/-3
Step-by-step explanation:
Slope = (y2 - y1)/(x2 - x1)
m = (8 - 3)/(-7 + 4)
m = 5/-3
Which pair of points have a slope of -3/5?
A (4, 0), (-2, 10)
B (10, -2), (0, 4)
C (4, 2), (10, 4)
D (-4, -10), (0, -2)
Answer:
No of these answers has a slope of [tex]\frac{-3}{5}[/tex] . My guess is B becasue its close to [tex]\frac{-3}{5}[/tex] unless the 5 is supposed to be negative
Step-by-step explanation:
You have to use the slope formula [tex]\frac{y_{2} - y_{1} }{x_{2} - x_{1} }[/tex]
([tex]x_{1}[/tex],[tex]y_{1}[/tex]), ([tex]x_{2}[/tex],[tex]y_{2}[/tex])
(4, 0), (-2, 10) [tex]\frac{10 - 0 }{-2 - 4 }= \frac{10}{6}[/tex] you have to simplfy, the answer will be [tex]\frac{5}{3}[/tex]
(10, -2), (0, 4) [tex]\frac{4 - -2 }{0- 10 }= \frac{6}{-10}[/tex] you have to simplfy, the answer will be [tex]\frac{3}{-5}[/tex]
(4, 2), (10, 4) [tex]\frac{4 - 2 }{10 - 4 }= \frac{2}{6}[/tex] you have to simplfy, the answer will be [tex]\frac{1}{3}[/tex]
(-4, -10),(0, -2) [tex]\frac{{-2- -10} }{0 - -4 }= \frac{8}{4}[/tex] you have to simplfy, the answer will be [tex]\frac{2}{1} =2[/tex]
a - 2 + 3 = -2
Please answer with solving steps!
Answer: a=−3
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
a−2+3=−2
a+−2+3=−2
(a)+(−2+3)=−2(Combine Like Terms)
a+1=−2
a+1=−2
Step 2: Subtract 1 from both sides.
a+1−1=−2−1
a=−3
Answer:
a=-1
Step-by-step explanation:
move -2 and 3 to the right side to have the variable by itself and then just add them together.
a = -2+3-2
a= -4+3
a= -1

What is the area of the parallelogram? 9 cm 6 cm 8 cm
Answer:
92 ...... .......... ..........
Answer:
348 square units
Step-by-step explanation:
Let's find the area of the front, the bottom and the end:
(9)(6) + (9)(8) + (6)(8) = 54 + 72 + 48 = 174 square units
Since there are two of each of these areas, double 174 to obtain 348 square units
Find the radius of the button.
A circular button with a diameter of 28 millimeters.
The radius of the button will be 14 millimetres.
What is the radius of the circle?The radius of the circler is defined as the distance from the centre of the circle to the outermost surface of the circle. The diameter of the circle is the distance between the two points on the surface of a circle passing through the centre of the circle.
Given that the diameter of the circle is 28 millimetres. the radius of the circle is calculated as,
Radius = Diameter / 2
Radius = 24 / 2
Radius = 12 millimetres
Therefore, the radius of the button will be 14 millimetres.

Select ALL that apply.
9(x - 3)
3(3x - 9)
x(9x - 3)
3(3x - 7)
3(x - 9)
Answer:
1) 9(x - 3) = 9x - 27. So, 1) applies.
2) 3(3x - 9) = 9x - 27. So, 2) applies.
3) x(9x - 3) = 9[tex]x^{2}[/tex] - 3x. So, 3) dosn't apply.
4) 3(3x - 7) = 9x - 21. S0, 4) dosn't apply.
5) 3(x - 9) = 3x - 27. So, 5) also dosn't apply.
Step-by-step explanation:
1) 9(x - 3) = 9x - 27. So, 1) applies.
2) 3(3x - 9) = 9x - 27. So, 2) applies.
3) x(9x - 3) = 9[tex]x^{2}[/tex] - 3x. So, 3) dosn't apply.
4) 3(3x - 7) = 9x - 21. S0, 4) dosn't apply.
5) 3(x - 9) = 3x - 27. So, 5) also dosn't apply.
The expressions that are equivalent to 9x - 27 are:
9(x - 3)
3(3x - 9)
To determine which expressions are equivalent to 9x - 27, let's simplify each of the given options:
9(x - 3):
Expanding the expression, we get 9x - 27.
This expression is equivalent to 9x - 27.
3(3x - 9):
Expanding the expression, we get 9x - 27.
This expression is equivalent to 9x - 27.
x(9x - 3):
Expanding the expression, we get 9x² - 3x.
This expression is NOT equivalent to 9x - 27.
3(3x - 7):
Expanding the expression, we get 9x - 21.
This expression is NOT equivalent to 9x - 27.
3(x - 9):
Expanding the expression, we get 3x - 27.
This expression is NOT equivalent to 9x - 27.
Therefore, the expressions that are equivalent to 9x - 27 are:
9(x - 3)
3(3x - 9)
So, the correct options are 1 and 2.

A library has 2000 books. There are 3 times as many non fiction books as fiction books. Write and solve an equation. PLEASE HELP ASAP!!!???
Answer:
x = fiction books
3x = nonfiction books
x + 3x = 2000
After you solve for x, (which is the number of fiction books), you can plug its value into the equation for nonfiction books (3x) and that will give you the number of non fiction books.

Write an exponential function to describe the given sequence of numbers, assuming that the first number in the sequence corresponds to x = 0.
5.30, 180, 1080, 6480...
Answer:
[tex]y = 5(6) {}^{x} [/tex]
Step-by-step explanation:
A exponential function is represented by
[tex]y = ab {}^{x} [/tex]
where a is the vertical stretch and b is the base and x is the nth
power of x
Since the first number corresponds with zero, that means our y intercept is the first number.
This means when x=0 , y=5 so let find the value of 5.
[tex]5 = ab {}^{0} [/tex]
b to the 0th power equal 1 so
[tex]5 = a \times 1[/tex]
[tex]a = 5[/tex]
Our equation is for now
[tex]y = 5b {}^{x} [/tex]
Now let plug in 1,30
[tex]30 = 5b {}^{1} [/tex]
Divide 5 by both sides
[tex]6 = b {}^{1} [/tex]
Anything to the 1st power is itself so b equal 6.
So our equation is
[tex]y = 5(6) {}^{x} [/tex]

Answer:
4 12/18, simplified is 4 6/9
Step-by-step explanation:
You change the fractions to improper fractions so 10 1/2 to 21/2 and 2 1/4 to 9/4. Since we can't divide, we change 9/4 to 4/9 and multiply. 21 times 4 is 84 and 2 times 9 is 18. Since that is an improper fraction, we have to change it to a mixed number. 18 can go into 84 4 times, and 18 x 4 is 72. 84 minus 72 is 12 so the final answer is 4 12/18 (simplified 4 6/9)

Answer:
$129,992
Step-by-step explanation:
The sum of a geometric series is given by ...
Sn = a1·(r^n -1)/(r -1)
Here, the first term is 24000, and the growth factor r is 1+4% = 1.04. The sum is then ...
S5 = 24000·(1.04^5 -1)/(1.04 -1) ≈ 129992
The total earned over 5 years was $129,992.

Add 5 to both sides
[tex]3x-5+5=9+5[/tex]
Simplify
[tex]3x=14[/tex]
Divide both sides by 3
[tex]\frac{3x}{3}=\frac{14}{3}[/tex]

Therefore, the value of x = 14/3

Find the area of the shape below giving your answer to 1 decimal place.
Answer:
198.5 cm²
Step-by-step explanation:
From the figure above we can treat the two semi circles as 1 circle.
Now, the diameter is 10 cm
Thus;
Radius; r = 10/2
r = 5cm
Now, formula for area of a circle is;
A = πr²
Thus;
Area of 2 semi circles = Area of 1 circle = π × 5²
A_circle = 78.54 ≈ 78.5 cm²
When we take out the 2 semi circles, what we have left is a rectangle.
Now, the length of the rectangle will be;
Length; L = 22 - 5 - 5 = 12 cm
*This is because the radius of the semi circle is 5 and distance from the edge of the 22 cm length to the centre of the semi circle is 5 cm
Thus, area of rectangle is given by;
A_rect = LW
W in the image is 10 cm
Thus;
A_rect = 12 × 10
Total area of shape is;
A_total = 120 + 78.5
A_total = 198.5 cm²
