Answer:
The total number of cupcakes that Natalie dropped is 7.
Step-by-step explanation:
This question can be solved using a rule of three.
The amount of cupcakes that she has, which is 20, is 100% = 1. How many cupcakes is 35% = 0.35?
20 cupcakes - 1
x cupcakes - 0.35
x = 20*0.35 = 7
The total number of cupcakes that Natalie dropped is 7.
What you would do is that you would use the y=mx+b linear equation
m=5
x=-1
y=-3
b=?
hence, you must solve b to have the equation
-3=(5)(-1)+b
-3=-5+b
-3+5=b
2=b
therefore the equation is
y=5x+2
for standard form you just move everything to equal 0 because there is no fraction next to the x
thus
-5x+y-2=0
Ans: A, you’re correct
(f-g)(x) = f(x)-g(x)
6x3-4-(2x+2)
=6x3-4-2x-2= 6x3-2x-6
Answer:
-5 < x < 10
Step-by-step explanation:
−6 < x − 1 < 9 just get rid of -1 by adding 1 to all three terms
-6 + 1 < x -1 + 1 < 9 + 1
-5 < x < 10

Answer:
Step-by-step explanation:
For this to have infinitely many solutions, the left side and right side must simplify to the same expression. The left side is already simplified, so we need to find the right numbers for the right side.
Coefficient of x:
7x = __x + 3x
4x = __x . . . . . . subtract 3x; next divide by x
4 = __ . . . . . the required x-coefficient is 4
Constant term:
-8 = 8 -__
-16 = -__ . . . . . subtract 8
16 = __ . . . . . . multiply by -1
__
The numbers that go in the boxes are 4 and 16.
