X1,2= -(-7)±√(-7)^2-4*4(-3)/2*4

-3/7(21x+7)=-7x+11
A.) x=-7/8
B.) x=-7
C.) x=7
D.) x=-7/8
Answer:
B
Step-by-step explanation:
-3/7 (21x + 7) = -7x + 11
Let's simplify the left side real quick
Distribute the -3/7
(-3/7)21x + 7(-3/7)
-63x/7 + -21/7
-9x - 3 = -7x + 11
Move like terms to one side
Let's move the variables to the left side by adding both sides by 7x
-9x - 3 = -7x + 11
+7x +7x
-2x - 3 = 11
Add both sides by 3
-2x - 3 = 11
+3 +3
-2x = 14
Divide both sides by the coefficient, -2, to isolate the variable, x
-2x/-2 = 14/-2
x = -7

Solve the proportion below.
90/x=3/4
x =
O A. 91
B. 120
C. 150
O D. 99
Answer:
B) 120
Step-by-step explanation:
Initial problem: 90/x = 3/4
Cross multiply to get:
90*4 = 3x
360 = 3x
x = 120
Check (optional):
90/120 = 3/4
(simplify):
3/4 = 3/4 so it is correct
If you're confused about any of these steps, just let me know and I'll try to help!
The value of x would be B. 120
To solve the proportion 90/x = 3/4, we can use cross-multiplication. Cross-multiplication involves multiplying the numerator of the first fraction (90) with the denominator of the second fraction (4), and multiplying the numerator of the second fraction (3) with the denominator of the first fraction (x).
So, the equation becomes:
90 * 4 = 3 * x
Simplifying:
360 = 3x
Now we divide both sides of the equation by 3:
360/3 = 3x/3
120 = x
Therefore, x = 120.
The correct answer is option B. 120.

What is the volume of the following
rectangular prism?
2 units
units
7 1/3
Answer:
44/3 units cubed
Step-by-step explanation:
The volume of the given rectangular prism will be 14.67 cubic units.
What is the volume of the rectangular prism?Let the prism with a length of L, a width of W, and a height of H. Then the volume of the prism is given as,
V = L x W x H
The area of one face is 7 ¹/₃ square units. And height is 2 units.
First, convert the mixed fraction number into a decimal number.
L x W = 7¹/₃
L x W = 7 + 1/3
L x W = 7 + 0.33
L x W = 7.33
Then the volume of the prism is calculated as,
V = L x W x H
V = 7.33 x 2
V = 14.67 cubic units
The volume of the given rectangular prism will be 14.67 cubic units.

Statement B is an example of (A. Deducting reasoning B.inducting reasoning)The statement (A. applies and established truth to a specific example B. Uses previous examples to make a conjecture)
Answer: here it is
Step-by-step explanation:
Statement A is an example of inductive statement, whereas, statement B is a example of deductive statement.
What is inductive reasoning?Inductive reasoning is a method of reasoning in which a body of observations is considered to derive a general principle. It consists of making broad generalizations based on specific observations.
For example,
The last few times I’ve driven past the beach on a sunny day, the parking lot was nearly full. Therefore, on sunny days, the beach parking lot will be nearly full.
What is deductive reasoning?Deductive reasoning is the mental process of drawing deductive inferences. An inference is deductively valid if its conclusion follows logically from its premises, i.e. if it is impossible for the premises to be true and the conclusion to be false.
For example,
On Thursdays, the trash gets picked up at the curb of the driveway. Today is Thursday. Therefore, the trash will get picked up at the curb of the driveway today.

Answer: Ray AC is correct
This is because ray AE points in the same direction along ray AC. Put another way, points C and E are on the same line as A. So relabeling from "ray AE" to "ray AC" does not change the ray itself.
Keep in mind that order is important. So saying "ray AE" is completely different from "ray EA" due to the fact that the first letter is the endpoint while the second letter is where the ray goes on forever. So we can think of starting at point A and going in the direction of E to get ray AE, or going in the direction of C to get ray AC, and we're talking about the same ray.

Write expression as a sine or cosine of an angle.
cos 94° cos 18° + sin 94° sin 18°
=========================================================
Explanation:
The original expression is of the pattern cos cos + sin sin. This pattern matches the second identity in the hint. Specifically, we'll say the following:
cos(A - B) = cos(A)cos(B) + sin(A)sin(B)
cos(A)cos(B) + sin(A)sin(B) = cos(A - B)
cos(94)cos(18) + sin(94)sin(18) = cos(94 - 18)
cos(94)cos(18) + sin(94)sin(18) = cos(76)
----------
We can verify this by use of a calculator. Make sure your calculator is in degree mode.
cos(94)cos(18) + sin(94)sin(18) = 0.24192cos(76) = 0.24192Both expressions give the same decimal approximation, so this helps confirm the two expressions are equal. You could also use the idea that if x = y, then x-y = 0. Through this method, you'll subtract the left and right hand sides and you should get (very close to) zero.
