Which of the following lies on the line y =- 3x + 2?
(A) (-1, 8)
(B) (0, 4)
(C) (2, -4)
(D) (5, - 10)
Answer:
C
Step-by-step explanation:
I can't say for sure, but I am confident that is the right answer.
will the point (2, 6) be on the graph of y=3x
Answer:
the answer is yes it will
Answer:
yes
Step-by-step explanation:
since (x,y) is 2,6, we can take x as 2 and y as 6. For the answer to be yes, y=3x must be equal to the x and y values. Lets plug in the values. Is (6)=3(2)?
3 times 2 is 6! So the answer is yes.
if a quadratic equation with real coefficients has a discriminant of -2, then its roots must be
A:2 real
B:1 real

Answer:
2/11
Step-by-step explanation:
These are division problems.
[tex] \frac{1}{2} \div 2 \frac{3}{4} [/tex]
convert 2 3/4 to an improper fraction. 4 x 2 + 3
[tex] \frac{1}{2} \div \frac{11}{4} [/tex]
keep change flip

The answer to this question
Answer:
113=x
Step-by-step explanation:
seeing as how the sum of all angles in a triangle is 180 degrees, we can get an equation:
28+39+x=180
simplify to get:
67+x=180
subtract 67 from both sides to get your answer:
113=x
Answer:
[tex]x=113[/tex]
[tex]y=67[/tex]
[tex]z=49[/tex]
Step-by-step explanation:
To find x:
We can use the angle sum property of a triangle which states that, The sum of all internal angles of a triangle is always equal to 180°.
Therefore, [tex]28+39+x=180[/tex]
[tex]67+x=180[/tex]
[tex]x=180-67[/tex]
[tex]x=113[/tex]
Now that we know the value of [tex]x[/tex] we can use it to find the value of [tex]y[/tex].
We can see that angle [tex]x[/tex] and [tex]y[/tex] are supplementary which means:
[tex]x+y=180[/tex]
[tex]113+y=180[/tex]
[tex]y=180-113[/tex]
[tex]y=67[/tex]
Now that we know the value of [tex]y[/tex] we can use the angle sum property of a triangle again:
[tex]64+y+z=180[/tex]
[tex]64+67+z=180[/tex]
[tex]131+z=180[/tex]
[tex]z=180-131[/tex]
[tex]z=49[/tex]
please help me!! Will give Brainly if correct
Answer:
-1
Step-by-step explanation:
Let's take two points on the line- (0,2) and (2,0).
To find the slope:
[tex]m = \frac{y_2 - y_1}{x_2-x_1}\\m = \frac{0 - 2}{2-0}\\m = \frac{-2}{2}\\m = -1[/tex]
The slope is -1.

Step-by-step explanation:
If a rock was thrown at t-2.23tp and hits its height at 1.56 meters what was the height of the tower?
Answer:
t = 4.875 s
h(4.875) = 686.25 ft
t ≈ 11.424 s
Step-by-step explanation:
These questions are more easily answered if the equation is written in vertex form. Subtracting the constant and dividing out -16, we get ...
h(t) -306 = -16(t^2 -9.75t)
Adding the square of half the t-coefficient inside parentheses gives ...
h(t) -306 -380.25 = -16(t^2 -9.75t +23.765625)
h(t) = -16(t -4.875)^2 + 686.25
This tells us the maximum height is 686.25 ft at time t = 4.875 seconds.
__
When the rock hits the ground, h(t) = 0, so ...
0 = -16(t -4.875)^2 + 686.25
686.25/16 = (t -4.875)^2 . . . . . subtract 686.25, divide by -16
√42.890625 +4.875 = t ≈ 11.424 . . . . take the square root, add 4.875
The rock hits the ground after about 11.424 seconds.

time in minutes. Define your variables.
How much does 30 minutes of computer time cost?
Answer:
[tex]c = 0.3m + 5[/tex]
define the variables:
c is the cost and m is minutes
It costs $14
Step-by-step explanation:
[tex]c = 0.3m + 5[/tex]
To solve for cost substitute 30 in for m
[tex]c = 0.3(30) + 5[/tex]
