yes
Hello!
The slope-intercept form is: y = mx + b. In this form, m is the slope and b is the y-intercept.
Since we are given the slope, which is -1/2, and the y-intercept which is (0, -3/4). This means that the value of b is -3/4.
So therefore, the equation of the function is: y = -1/2x + -3/4.
You can buy 15 ink cartridges from 180 dollars.
Step-by-step explanation:
Given,
Amount you have = 180 dollars
Cost of one cartridge of ink = 12 dollars
We will divide the total amount with the cost of one cartridge of ink to find the number of ink cartridges that can be bought.
Number of ink cartridges =
Number of ink cartridges = 15
You can buy 15 ink cartridges from 180 dollars.

Step-by-step explanation:
Answer:
ED = 4
Step-by-step explanation:
A & B) Triangles FGD and DGE are similar. Set <DFG to x. We can say that m<DGF, m<DGE, and m<EDF are 90 because they are right. Using triangle angle sum theorem in triangle DEF, we can say that m<DEG = 90 - x. And we can use it again to say in triangle FGD to say m<FDG is also 90-x. From AA we can say the triangles FGD and DGE are congruent.
C) In addition to the two triangles above, triangle FDE would also be congruent due to AA. We can write the following equations using the properties of similar triangles:
DGE FDE
EG = ED*y --> 2 = ED*y
ED * 1/y = EF --> ED * 1/y = 8 --> ED = 8y
We can substitute:
2 = 8y^2
1/4 = y^2
y = 1/2
This means ED = 8y = 8(1/2) = 4 --> ED = 4
