Answer:
-15, -17
Step-by-step explanation:
x^2 + 32x = –255 move the -255 to the left
x^2 + 32x +255=0
What two number when multiplied equal 255? Those same two numbers when added make 32. 17*15 make 255 and added is 32
(x+15)(x+17) For x+15=0 move the 15 to the other side. x= -15. Same with x+17=0 is x= -17
x= -15, -17
4/3 divided by 2/5...............
Answer:
[tex]3 \frac{1}{3}[/tex], or 10/3
Step-by-step explanation:
4/3 ÷ 2/5 = 4/3 × 5/2 = 20/6 = [tex]3 \frac{2}{6} = 3\frac{1}{3}[/tex]
Answer:
3 1/3
Step-by-step explanation:
When we divide two fractions, such as 4/3 ÷ 2/5, we flip the second fraction and then we simply multiply the numerators with each other and the denominator with each other.
We also simplify the answers to fraction problems whenever possible.
So first we will change 2/5 into its reciprocal, in simple words what fraction is it when its flipped over, 5/2 right? So now we change the division into multiplication, you may or may not have heard this phrase:
Keep, Change, Flip
so now our equation looks like this:
4/3 (5/2)
In a multiplication problem it dosent matter if the denominators are the same so we just straight up multiply, which gives us 20/6. We can still simplify this by 2, so 20 divided by 2 is 10, and 6 divided by 2 is 3, so our new fraction is 10/3, now we can simplify it again to make it proper, so its 10 divided by 3, the numerator goes inside and the denominator goes outside, this gives us 3r1, the denominator (the outside number) will becomes the mixed number, the remainder will become the numerator, and the answer will become the denominator, which gives us our final answer of:
3 1/3

Is y = 9x + 1/2 proportional?
Answer:
Yes it is
Step-by-step explanation:
The equation is proportional since as the value of x is increasing, y is also increasing
Equations can either be direct, inverse, or even joint. For instance, if y is directly proportional to x, this is expressed as:
y = kx
k is the variation constant
For a proportional equation, there an increase in a variable will lead to a decrease or increase in other variables
Given the expression y = 9x + 1/2,
when x = 1
y = 9(1) + 1/2
y = 9.5
when x = 2
y = 9(2) + 1/2
y = 18.5
We can see that the equation is proportional since as the value of x is increasing, y is also increasing

Find the slope-intercept equation of the line that
passes through (0,4) and has a slope of 1.
Answer:
y=1x+4 is the answer :))))
Answer:
y = x + 4
Step-by-step explanation:
slope intercept equation: y = mx + b
m = slope
b = y-intercept(when x =0)
use the points given; (0,4) and m = 1
to find b
y = mx + b
4 = 1(0) + b
4 = b
now put your equation together.
y = 1x + 4
or y = x + 4
