Answer: D. 38x + 1,450 > 4,000
Step-by-step explanation:
It has to be greater than 4,000 so A makes no sense
The parentheses are in the wrong place completely changing the meaning for B
C disregards the info we have about how she's already typed 1,450 words
The answer has to be D
Answer:
78
Step-by-step explanation:
Use PEMDAS for questions like these (Parenthesis, Exponents, Multiplication, Division, Addition, Subtraction) It gives an order in which you should solve the problem. In this case, put 46 instead of T to get (46*2)-14. If we look at PEMDAS, it shows that we need to do what is in the parenthesis first. So, 46x2=92. You get 92-14. Solve that and you get 78
There 2 angles are corresponding angles, in which the angle measurements would have the same degree.
Set the two angles equal to each other, and solve for x.
7x - 1 = 8x - 14
Isolate the x. Subtract 8x from both sides, and add 1 to both sides
7x (-8x) - 1 (+1) = -14 (+1)
7x - 8x = -14 + 1
-x = -13
Isolate the x. Divide -1 from both sides
(-x)/-1 = (-13)/-1
x = -13/-1
x = 13
13 is your answer for x.

6x-y+33=0
Step-by-step explanation:
m=y2-y1/x1-x2
m=1-(-3)/18-(-6)
m=4/24m=6
m=y-y1/x-x1
6=y-y1/x-x1
6x-y+33=0
Answer:
y = 10
Step-by-step explanation:
Given the 2 equations
y = - 2x + 4 → (1)
y = x² + 4x + 13 → (2)
Since both equations express y in terms of x we can equate them
x² + 4x + 3 = - 2x + 4 ( subtract - 2x + 4 from both sides )
x² + 6x + 9 = 0 ← in standard form
(x + 3)² = 0 ← in factored form
x + 3 = 0 ⇒ x = - 3 with multiplicity 2
Substitute x = - 3 into (1)
y = 6 + 4 = 10
