What is the value pls help

Answer:

(-10, -8), third quadrant

Step-by-step explanation:

8 down from (0, 0) is the same as subtracting 8 from the y coordinate → (0, -8). 10 left from (0, -8) is the same as subtracting 10 from the x coordinate → (-10, -8). You would be in the third quadrant where both coordinates are negative.

Let y be f(x)

[tex]\\ \sf\longmapsto y=4x-12[/tex]

Swipe the values

[tex]\\ \sf\longmapsto x=4y-12[/tex]

[tex]\\ \sf\longmapsto 4y=x+12[/tex]

[tex]\\ \sf\longmapsto y=\dfrac{x+12}{4}[/tex]

[tex]\\ \sf\longmapsto y=\dfrac{1}{4}x+3[/tex]

Hence.

[tex]\\ \sf\longmapsto f^{-1}(x)=\dfrac{1}{4}x+3[/tex]

Let y=f(x)

Now interchange the variables

The y we need now

Divide both sides by 4

This is the inverse

Answer:

Step-by-step explanation:

To solve, we first need to know how to find the average of a group of numbers. To find the average of a group of numbers, you add all the numbers together and divide that answer by the number of numbers you have. For instance, to find the average of 1, 2, 3, 4 and 5, we would add all the numbers together, which would equal 15. We would then divide that number by 5, because there are 5 numbers total: 15/5 = 3. So the average is 3.

Now, to find the average in your problem, we need to look at what we know:

He received an 85 and 60 on two of the test scores

He needs an overall average of 70

Let's set this up in equation form:

%2885+%2B+60+%2B+x%29%2F3+%3E=+70

Now, let's get rid of our fraction on the left. We can do this by multiplying the entire equation by 3, giving us:

85 + 60 + x >= 210

Next, combine the numbers on the left, which will give us:

145 + x >= 210

Finally, subtract 145 from both sides, which will give us our answer:

145 + x - 145 >= 210 - 145 =

x >= 65

So, in order to average at least 70, he must score a 65 or higher on his third test.

Answer:

250 : 500 : 750 : 1000

Step-by-step explanation:

Therefore the answer is,

1 : 2 : 3 : 4

250 : 500 : 750 : 1000

Answer:

an apple costs 0.24 and a pear costs 0.28

Step-by-step explanation:

      3a + 4p = 1.84                                 3a + 4p = 1.84

     -5a + 2p = 1.76   m(-2)                 -10a - 4p = -3.52

        3a + 4p = 1.84

 +   -10a - 4p = -3.52

       -7a          = -1.68

           a         = -1.68/-7

           a        =  0.24

       3a + 4p = 1.84

       3(0.24) + 4p = 1.84

       0.72  + 4p = 1.84

                   4p = 1.84 - 0.72

                    4p = 1.12

                      p = 0.28

The cost of an apple is £0.24 and the cost of pear is £0.28

A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.

Let a represent the cost of one apple and p represent the cost of one pear.

Then the system of equation will be;

     3a + 4p = 1.84                                

    -5a + 2p = 1.76   m(-2)                

-10a - 4p = -3.52

Solving both the equation;

-7a   = -1.68

a   = -1.68/-7

a   =  0.24

For solving p;

3a + 4p = 1.84

3(0.24) + 4p = 1.84

0.72  + 4p = 1.84

4p = 1.84 - 0.72

4p = 1.12

p = 0.28

Hence, the cost of an apple is £0.24 and the cost of pear is £0.28

Step-by-step explanation:

5⁴×5² = 5⁶

10⁶/10³ = 10³

so, we have 5⁶/10³ = 15.625

and in scientific notation we have to write the first digit (which is not 0) in front of the decimal point, and the following digits of the number as pairings after the decimal point, and then indicate a multiplication with a power of 10 to tell us the right position of the decimal point in the plain number.

so, 15.625 as plain number is

1.5625 × 10¹ in scientific notation.

therefore option 1 is correct.

Answer:

Step-by-step explanation:

x * y=-21

x+y =-10

we use elimination method to solve

x * y = -21

x + y = -10

x = -11

then replace the y s with -11

x * y = -21

x * -11 =-21

x *-11 + -11 = -21+-11

x = -32

x + y = -10

x +-11 = -10

x + -11--11 = -10--11

x + 0 = -10+11

x = 1

x =1

y = -11

Answer:

-2.5 or -5/2

Step-by-step explanation:

To find the slope we need to find the change in y and divide it by the change in x:

m = change in y ÷ change in x

m = (-5 - 20) ÷ (11 - 1)

m = 25 ÷ -10

m = -2.5 or -5/2
