Answer:

The x=8 is only for the x interecept, and the x-intercept is (8,0). You assume y to be 0 then you say it's 2, that is incorrect. x and y interecepts should not be combined. The correct x-intercept and y-intercept are (8,0) and (0,2) respectively

heres a neat trick you can do instead of doing that long process to get 15% of 5321 just use a calculator and do 5321 x .15

Answer:

Triangle RST is an equilateral triangle.

Step-by-step explanation:

All three sides of the triangle are of equal length, therefore, because an isosceles triangle is when 2 sides of the triangle are the same length, a scalene triangle being when all sides are of different lengths, and a right triangle having a right angle (a 90 degree angle), this only leaves equilateral, all three sides being the same length, like in the triangle shown.

Answer:

The first one is

Answer:

1/14

Step-by-step explanation:

slope = difference of y over difference of x

= (-3-(-4)) /(8 -(-6)) = 1/14

Answer:

Ummm...

8,784/61=

Answer:

Step 1: Subtract x from both sides.

2x+3−x=x−4−x

x+3=−4

Step 2: Subtract 3 from both sides.

x+3−3=−4−3

x=−7

Answer:

x=−7

Answer:

A: x = 20

Step-by-step explanation:

Answer: Its x=40

Step-by-step explanation: multiply 20 by 50 then divide the answer by x i got a 100 so yeee

Answer:

D

Step-by-step explanation:

cause its going bigger, but it also has 0 in the line so it could have 0 in it. So its D

Answer:

75 degrees

Step-by-step explanation:

All the angles within a triangle added together equals 180 degrees, so:

x + 25 + 2x - 5 + x = 180

add like terms

4x + 20 = 180

subtract 20 from both sides

4x = 160

divide by 4

x = 40

Now input 4 into the equation for C

2(40) - 5 = 80 - 5 = 75

Answer:

Step-by-step explanation:

y÷2+x

2÷2+1

1+1

2

Answer:

2

Step-by-step explanation:

If you insert what y and x are, the equation would be 2 divided by 2 plus 1.

2 divided by 2 is 1 then add one to get 2.

Answer:

Pretty sure its C becuase there is no “people” on the graph.

Answer:

1/2^4

Step-by-step explanation:

Answer:

(0,0) , (a,b) , (2a,2b) is the answer

Step-by-step explanation:

for a triangle to be isosceles, then two sides must be equal

To picture this, if we have a point at the origin, with coordinate (0,0); we can have the coordinates of the other points being the same so as to make the distance from the origin the same

Then from here, we can get that the length of the two sides are equal

From what we have, option 4 can be correct

This is because , finding the distance between two points is;

D = √(x2-x1)^2 + (y2-y1)^2

From what we have

The distance between (0,0) and (a,b) will give same answer for the distance between (a,b) and (2a,2b)

Answer:

Scalene – none of the sides of the triangle have equal lengths

Isosceles – two sides of the triangle have the same length

Equilateral – all sides of the triangle have the same length

1. Equilateral

2. Scalene

3. Isosceles

4. Isosceles

5. Isosceles

6. Isosceles

7. Isosceles

8. Equilateral

Answer:

Milla's account would earn $63 more that Gino's account after 1 year.

Step-by-step explanation:

Both Gino and Milla made an initial deposit of $6300.

Principal = $6300

Gino's rate = 2% = 0.02

Milla's rate = 3% = 0.03

number of years = 1

Interest = Principal x Rate x Time

So that,

for Gino;

Interest = 6300 x 0.02 x 1

            = 126

The interest on Gino's savings after a year is $126.

for Milla;

Interest = 6300 x 0.03 x 1

             = 189

The interest on Milla's savings after a year is $189.

Milla's interest - Gino's interest = 189 - 126

                                                   = 63

Milla's account would earn $63 more that Gino's account after 1 year.

Answer:

Answer:

-160

Step-by-step explanation:

All you have to do is substitute -2 for all values of x!

Is that last x raised to the power of 4 (looks like [tex]x^4[/tex])?

If so, the equation is:

[tex]f(-2)=2(-2-3)(-2)^4[/tex]

2(-5)(16)

-10(16)

-160

Answer:

You have to substitute the x-values into the function :

[tex]f(x) = {11}^{x} [/tex]

[tex]f( - 2) = {11}^{ - 2} = \frac{1}{121} [/tex]

[tex]f( - 1) = {11}^{ - 1} = \frac{1}{11} [/tex]

[tex]f(0) = {11}^{0} = 1[/tex]

[tex]f(1) = {11}^{1} = 11[/tex]

[tex]f(2) = {11}^{2} = 121[/tex]

Answer:

as long as the equation has no exponents or square roots it is linear

Step-by-step explanation:

Answer:

-2/1

Step-by-step explanation:

to find the slope it is rise over run so the rise is two and the run is 1 so its 2/1 but its negative so it would be -2/1

hope that halepd have a good night!! :)
