What multiplied to -24 and adds to -10?
Answer:
6 × 4 = 25
6 + 4 = 10
hope this helps
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
write the equation
it has y-intercept -8 and x-intercept 2
Step-by-step explanation:
(x/2) +(y/-8)=1
[tex] \frac{x}{2} - \frac{y}{8} = 1[/tex]
well that is the equation
Answer:
y=(y/x+8/x) x-8

Answer:
Number 3 is correct.
129.19m
Step-by-step explanation:
You might be wondering how did I got 32⁰, well, that's because they are alternate angles.
Now, we're trying to find the opposite side of the triangle.
Using the laws,
we got cos32⁰=x/243.8
243.8cos32⁰=x
129.19⁰

Starting at (0,0) if you were to go 8 units down and 10 units left what coordinates
would you end up at? What quadrant would you be in?
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.

What is the slope passing through the points (11,-5) and (1,20)
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

Let y be f(x)
[tex]\\ \sf\longmapsto y=4x-12[/tex]
Swipe the values
[tex]\\ \sf\longmapsto x=4y-12[/tex]
Isolate y[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)
y=4x-12Now interchange the variables
x=4y-12The y we need now
x+12=4yDivide both sides by 4
y=(x+12)/4This is the inverse

Can someone help me please
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.

Ted needs an average of at least 70 on his three day history tests. He has already scored 80 and 60 on two tests. What is the minimum grade Ted needs on his third.
Thank you for your assistance
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.
