what is the slope?
please hurry!
y=-x - 3
Answer:
Step-by-step explanation:
slope =
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
y + 3 = (x - 2) is in this form
with slope m =
Answer:
-x is the slope

4
8
6
2
Answer:
4
Step-by-step explanation:
First, solve for x:
4 + 2(3x - 4) = 8
4 + 6x - 8 = 8
6x = 12
x = 2
Now, plug x into 4x - 4:
4(2) - 4 => 8 - 4 = 4
Drag each tile to the correct box
Place the circles in order from the circle with the SMALLEST area to the circle with the LARGEST area.
Answer:
Smallest to largest:
The circle with a diameter of 19
The circle with a circumference of 87.92
The circle with the area of 1,040.09
The circle with the radius of 27
Step-by-step explanation:
-The formula for the area is pi x r^2
-The diameter is double the radius, meaning divide it by 2 to get the radius.
-The formula for a circumference is 2 x pi x r meaning, do the reverse to get the radius. (87.92 divided by pi and then by 2 gives you the radius.)
-pi is equal to 3.14

What is the solution to the equation?
Answer:
Step-by-step explanation:
[tex]\sqrt[3]{x+4}+\sqrt[3]{2x +8}=0\\\\\sqrt[3]{x+4}= -\sqrt[3]{2x + 8}\\\\(x +4)^{\frac{1}{3}}=-(2x+8)^{\frac{1}{3}}\\\\[/tex]
Take cube,
[tex][(x+4)^{\frac{1}{3}}]^{3} =- [(2x +8)^{\frac{1}{3}}^{3}]\\\\(x+4)^{3*\frac{1}{3}}=-(2x + 8)^{3*\frac{1}{3}}\\\\[/tex]
x + 4 = - (2x + 8)
x +4 = 2x *(-1) + 8 *(-1)
x+ 4 = -2x - 8
x +2x+4 = - 8
3x + 4 = - 8
3x = - 8 -4
3x = -12
x = -12/3
x = -4

Isabella opened a savings account and deposited $25,000.00. The account earns 20% interest, compounded annually. If she wants to use the money to buy a new car in 2 years, how much will she be able to spend on the car?
Answer:
$11,000
Step-by-step explanation:
1st year the account earned 20% from $25,000 = $5,000 | total = $30,000
2nd year the account earned 20% from $30,000 = $6,000
by adding the earnings of 2 years, she will be able to spend $5,000 + $6,000 = $11,000

Darrens garden is 4 4/6 feet long. Zanique’s garden is 2 1/3 shorter. Find the length of Zanique’s garden.
4 - 2 = 2
If you take 3 and add 3, you get 6, and if you take 1 and add 1 you get 2, so 2/6.
4/6 - 2/6 = 0.33333333333
So I'd say about 2.3333333333 is the length of Zanique's garden, in a fraction... um... 233333333333/10000000000
That's all I could come up with. Don't judge me
Use prime factorization to reduce the fraction 36/180
Answer:
Step-by-step explanation:
36 = 6* 6 = 2* 3 * 2* 3 = 2*2*3*3
180 = 2 * 2 * 3 * 3 * 5 = 2 * 2 * 3*3*5
[tex]\frac{36}{180}= \frac{2*2*3*3}{2*2*3*3*5} = \frac{1}{5}[/tex]

Sum of exterior angles of a polygon is 360°#8
2x + 2(64°) + 36° + 48° = 360°2x + 212° = 360°2x = 360° - 212°2x = 148°x = 74°#9
x + 73° + 109° + 90° = 360°x + 272° = 360°x = 360° - 272°x = 88°Simplify (8.3) 2.10.(6-1)

Filipe is buying materials for making his new comic books. He purchases a notebook for $7
and when he rings up it shows he also owes $0.42 in tax. If he buys markers the next day for
$6 and pays the same tax rate, how much will he pay in tax?
Answer:$0.36
Step-by-step explanation:
0.42 devided by 7= 0.06
0.06 times 6= 0.36
Answer:
He would pay $0.36 the next day if he buys markers and pays the same tax rate as day 1.

Solve the system of equations
-12x+9y=7
3x+4y=2
Show all workings please
Answer:
x = -2/15 & y = 3/5
Step-by-step explanation:
- 12x + 9y = 7 ...(1) ; 3x + 4y = 2 ...(2)
Multiply both sides of (2) by 4:
12x + 16y = 8
Add the new equation & (1):
12x + 16y = 8
-12x + 9y = 7
0 + 25y = 15 => y = 15/25 = 3/5
Thus, substitute the value of y in (2):
3x + 4y = 2 => 3x = 2 - 4(3/5) = (10-12)/5
=> 3x = -2/5
=> x = - 2/15
Answer:
[tex]x=-\frac{2}{15}=-0.133333333\\y = \frac{3}{5}= 0.6[/tex]
Step-by-step explanation:
−12x+9y=7
3x+4y=2
In order to solve by elimination, coefficients of one of the variables must be the same in both equations so that the variable will cancel out when one equation is subtracted from the other.
−12x+9y=7,3x+4y=2
To make −12x and 3x equal, multiply all terms on each side of the first equation by 3 and all terms on each side of the second by −12.
3(−12)x+3×9y=3×7,−12×3x−12×4y=−12×2
Simplify.
−36x+27y=21,−36x−48y=−24
Subtract −36x−48y=−24 from −36x+27y=21 by subtracting like terms on each side of the equal sign.
−36x+36x+27y+48y=21+24
Add −36x to 36x. Terms −36x and 36x cancel out, leaving an equation with only one variable that can be solved.
27y+48y=21+24
Add 27y to 48y.
75y=21+24
Add 21 to 24.
75y=45
Divide both sides by 75.
y=3/5
Substitute 3/5 for y in 3x+4y=2. Because the resulting equation contains only one variable, you can solve for x directly.
3x+4×(3/5)=2
Multiply 4 times 3/5
3x+12/5=2
Subtract 12/5 from both sides of the equation.
3x=-2/5
Divide both sides by 3.
x=-2/15
The system is now solved.
x=−2/15 ,y=3/5

B)

C)
65.825
D)
124.365
Answer:
[tex]\Huge\boxed{B.18.610}[/tex]
Step-by-step explanation:
Hello There!
We can find y by using trigonometric ratios
sine, cosine and tangent
[tex]tan= \frac{opposite}{adjacent}[/tex]
the opposite of the angle that has a measure of 28 degrees is y and the side that is adjacent to the angle is 35
so...
[tex]tan28=\frac{y}{35}[/tex]
now we solve for y using basic algebra
we want to isolate the variable (y) using inverse operations
to get rid of the 35 we multiply each side by 35
[tex]\frac{y}{35} =y\\tan28*35=35tan28[/tex]
now we let the calculator do the rest of the work
[tex]35tan(28)=18.60983011[/tex]
*round to the nearest thousandth*
we're left with
y = 18.610
hence your answer is B
