Answer: y = -0.5*x - 1
Step-by-step explanation:
A linear relationship can be written as:
y = a*x + b
where a is the slope and b is the y-axis intercept.
For a line that passes through the points (x1, y1) and (x2, y2), the slope can be written as:
a = (y2 - y1)/(x2 - x1).
Here we know that we have a line that passes through the points (-2, 0) and (0, -1)
Then the slope for this line is:
a = (-1 -0)/(0 - (-2)) = -1/2 = -0.5
Then our line is something like:
y = -0.5*x + b
now we know that this line passes trough the point (0, -1), this means that when x = 0, y must be equal to -1
Then we can replace these values in the equation in order to find the value of b.
-1 = -0.5*0 + b
-1 = b
Then the equation is:
y = -0.5*x - 1
how do you solve (7^-1)^-1 and 5^2 * 5^4 * 5^-3
Answer:
Step-by-step explanation:
exponents raised to a - power is an inverse function probably not the right word
a^-b = 1/(a^b) example 4^-2 = 1/(4^2) = 1/16
so (7^-1)^-1 is a double inverse which is back to the original number 7
inverted 7 twice
(7^-1)^-1 = (1/7)^-1 = 1/(1/7) = 7 trust me or use your calculator
since the coeffients are the same just add the powers... some exponent rule
5^2 * 5^4 * 5^-3 = 5^(2+4-3) = 5³
here is it written out
5^2 * 5^4 * 5^-3 = 5² × 5^4 × 5^-3 = (5×5) × (5×5×5×5) × (1/5×1/5×1/5)
5×5 × 5× (5×5×5 × 1/5×1/5×1/5) (5×5×5 × 1/5×1/5×1/5) = 1
5×5×5 = 5³
so

Find the measure of segment `DE.`
Answer:
DE=24
Step-by-step explanation:
We can see clearly that the two angles, angle A and angle F are congruent with one another, and since they are, we know the two triangles are shifted in a growth, not in an adjustment of angles. the hypotenuse doesnt matter, what does matter is the 5 and the 10, clearing showly the transition of Triangle ABC to Triangle DEF is times 2. Therefore, 12 times 2 is 24.
Answer:
Step-by-step explanation:
segment DE is what we want to find
notice that the two triangles are similar, similar here just means one is an exact copy of the other, except for scale. One is an exact scale copy of the other. sooooo we can make some scaling of one side of one.. to the same side of the other. here we want DE so .. see that BC is the same side on the other , smaller triangle?
now notice AB on the small triangle and FE on the bigger one... sooo just by observation we can see, that the bigger triangle is 2X bigger than the small one , b/c 5 * 2 = 10 . 5 is the AB side of the smaller triangel and 10 is the same side but on the bigger triangle and 2 is our scaling factor.. got it?
So do the same on BC to find DE
12 * 2 = DE
24 = DE
see? :)
A major credit card company requires monthly payments equal to or greater than 8% of the total balance.A consumer has a credit card balance of $320. Write an inequality that represents acceptable payment amounts.
Answer:
320 x 0.08 = X
In the case, a payment equal to or greater than $ 25.60 would be considered acceptable by the company.
Step-by-step explanation:
Given that a major credit card company requires monthly payments equal to or greater than 8% of the total balance, and a consumer has a credit card balance of $ 320, the following calculations must be performed to determine an inequality that represents acceptable payment amounts:
320 x 0.08 = X
25.6 = X
Thus, in the case, a payment equal to or greater than $ 25.60 would be considered acceptable by the company.

Diego is asked to solve 3x−8=4(x+5). What do you recommend he does to each side first?
Answer:
He would factor out 4(x+5)
Step-by-step explanation:
You can't do much until the 4(x+5) is factored out.
Once it is then it'd be 3x-8=4x+20
Then you subtract 3x on both sides and subtract 20 on both sides.
You'd be left with -28=x
Hope this helps

to increase the mean of 4 numbers by 2, by how much would the sum of the 4 numbers have to increase? check image.
Answer:
8
Step-by-step explanation:
x=average
(x+x+x+x)/4=average
to increase x by 2 you add 2
x+2=average
(x+2+x+2+x+2+x+2)=4=(4x+8)/4=x+2
you'd have to increase the sum by 8 to make the numbers' averages' go up by 2

Answer:
D. h(x) = 5x² +12x +9
Step-by-step explanation:
The final constants are mostly different, so you can simplify your work by just figuring that one.
h(x) = g(x) -f(x)
h(0) = g(0) -f(0) = -7 -(-16) = +9 . . . . . matches choice D
__
If you want to figure the whole expression ...
h(x) = g(x) -f(x)
h(x) = 12x² +7x -7 -(7x² -5x -16)
h(x) = 12x² +7x -7 -7x² +5x +16
h(x) = (12 -7)x² +(7 +5)x +(-7 +16)
h(x) = 5x² +12x +9 . . . . . matches choice D

A triangle has side lengths of (6p – 7) centimeters, (7p – 2) centimeters,
and (6q – 9) centimeters. Which expression represents the perimeter, in
centimeters, of the triangle?
Given:
A triangle has side lengths of (6p – 7) centimeters, (7p – 2) centimeters,
and (6q – 9) centimeters.
To find:
The expression that represents the perimeter, in centimeters, of the triangle.
Solution:
We know that, perimeter of a triangle is the sum of its all sides.
[tex]Perimeter=(6p-7)+(7p-2)+(6q-9)[/tex]
Combining like terms, we get
[tex]Perimeter=(6p+7p)+6q+(-7-2-9)[/tex]
[tex]Perimeter=(13p)+6q+(-18)[/tex]
[tex]Perimeter=13p+6q-18[/tex]
Therefore, the perimeter of the triangle is represented by the expression [tex]13p+6q-18[/tex] centimeters.
A triangle has side lengths of (6p – 7) centimeters, (7p – 2) centimeters, and (6q – 9) centimeters.
To find:
The expression that represents the perimeter, in centimeters, of the triangle.
Answer:
-18+13p+6q

which system of equations will yield the same solution to the system below?
x-y=3
2x-3y=-1
A- 2x-2y=-6
2x-3y=-1
B 2x-2y=6
2x-3y=-1
C -2x+2y=-3
2x-3y=-1
D 3x+3y=9
2x-3y=-1
Answer:
Step-by-step explanation:
In order for us to be able to find our answer, we need to show our work.
-3(x-y=3) → -3x + 3y = -9
+2x - 3y = -1
____________________________
-1x = -10
-1 -1
We need to divide -1 both sides in order for us to be able to find our x-value but there's more to this than just solving for X.
x = 10
x - y = 3
10 - y = 3
-10 -10
_________________
-y = -7
-1 -1
We need to divide -1 both sides in order for us to be able to find our y-value. Please note that each y is equivalent to an invisible 1.
y = 7
As a result, your answer will be B.
