4x^2+3=43 solve algebraically
Answer:
[tex]a)\ x_1=-3i,\ x_2 =3i[/tex]
[tex]b)\ x_1=-\sqrt{10},\ x_2=\sqrt{10}[/tex]
Step-by-step explanation:
Given equations:
[tex]a)\ x^2+19=10\\\\b)\ 4x^2+3=43[/tex]
A. x² + 19 = 10
Step 1: Subtract 19 from both sides.
[tex]\\\implies x^2+19-19=10-19\\\\\implies x^2=-9[/tex]
Imaginary number rule: For any positive real number "k", [tex]\sqrt{-k} = i\sqrt{k}[/tex]
Note: Two imaginary (complex) solutions indicate that the graph will not intersect the x-axis. As a result, it has no real roots.
Step 2: Take the square root of both sides (positive and negative roots).
[tex]\\\implies \sqrt{x^2}=\sqrt{-9}\\\\\implies x=\pm\ i\sqrt{9}\\\\\implies x=\pm\ 3i[/tex]
Step 3: Separate the solutions.
[tex]\implies x_1=-3i,\ x_2 =3i[/tex]
----------------------------------------------------------------------------------------------------------------
B. 4x² + 3 = 43
Step 1: Subtract 43 from both sides.
[tex]\\\implies 4x^2++3-3=43-3\\\\\implies 4x^2=40[/tex]
Step 2: Divide both sides by 4.
[tex]\\\implies 4x^2=40\\\\\implies \dfrac{4x^2}4=\dfrac{40}{4}\\\\\implies x^2=10[/tex]
Step 3: Take the square root of both sides (positive and negative roots).
[tex]\\\implies \sqrt{x^2}=\sqrt{10}\\\\\implies x=\pm\ \sqrt{10}[/tex]
Step 4: Separate the solutions.
[tex]\implies x_1=-\sqrt{10},\ x_2=\sqrt{10}[/tex]

Maria and Veronica were asked to add two whole numbers. Instead, Maria subtracted the two numbers and got 10 while Veronica multiplied them and got 651. What was the correct sum
Answer:
31 + 21 = 52
Step-by-step explanation:
Calculation for the correct sum
First step is to factor 651 which means that 1 * 3 * 7 * 31 will give us 651
Second step is to find 3 possibilities numbers that will give us 10 as the difference
3 possibilities numbers =(31, 21), (93, 7), (217, 3)
Third step is to make use of equation 1 to find the numbers that has 10 as the difference among the 3 possibilities numbers
The number that has 10 as the difference is (31, 21) because 31-21 will gives us 10
Now Equation 1 = X – Y = 10
Where,
X=31
Y=21
Hence,
31 – 21 = 10
Since 31 – 21 gave us 10 as the difference which means that the correct sum will be:
Correct sum =31 + 21 = 52
Therefore the Correct sum is 31 + 21 = 52
Solve for x.

Write an exponential function in the form y=ab^x that goes through points (0,9) and (3, 576)
Answer:
An exponential function in the form y=9(4ˣ)
Step-by-step explanation:
Step(i):-
Given that exponential function
y = a bˣ ...(i)
The equation (i) passes through the point (0,9)
9 = a (b )⁰ = a
a =9
Step(ii):-
The equation (i) passes through the point (3,576)
576 = 9(b)³
⇒ [tex]\frac{576}{9} = b^{3}[/tex]
⇒ 64 = b³
⇒ 4³ = b³
[tex](4^{3} )^{\frac{1}{3} } = (b^{3} )^{\frac{1}{3} }[/tex]
b = 4
Final answer:-
An exponential function in the form y=abˣ
An exponential function in the form y=9(4ˣ)

Find the value of x.

Answer:
x = 70
Step-by-step explanation:
180* (n-2)
180*(6-2)
180*(4) = 720
102 + 146 + 120 + 124 + 158 = 650
720 - 650 = 70
A polygon is a planar figure characterized by a limited number of straight-line segments. The value of the x is 70°.
What is a polygon?A polygon is a planar figure characterized by a limited number of straight-line segments joined to create a closed polygonal chain in geometry. A polygon is defined as a bounded planar region, a bounding circuit, or both.
The sum of the interior angles of a n-sided polygon is calculated using the formula,
Sum of the interior angles = (n-2) × 180°
For the given polygon, the number of sides is equal to 6. Therefore, the sum of the interior angles of the polygon is,
Sum of the interior angles = (6-2) × 180°
= 4 × 180°
= 720°
Further, the sum of the interior angles for the given polygon can be written as,
Sum of the interior angles = 102° + 146° + 120° + 124° + 158° + x°
720° = 102° + 146° + 120° + 124° + 158° + x°
x = 720° - (102° + 146° + 120° + 124° + 158°)
x = 720° - 650°
x = 70°
Hence, the value of the x is 70°.

Can anybody help me with these two !
Don’t answer if you do not know please
I’ll mark you as a brainliest:) .
Answer:
Step-by-step explanation:
a) Since we know that y=x^3, we can plug the values in
They would be: (-2)^3, (-1)^3, (0)^3, (1)^3, and 2^(3)
Which would be -8, -1, 0, 1, and 8
b) since we know that y=x, we can plug the values in
They would be -2, -1, 0, 1, and 2 because x = y

Do 4x and 15+x have the same value when x is 5?
Are 4x and 15+x equivalent expressions? Explain your reasoning.
Answer:
1. yes 2. no
Step-by-step explanation:
Hi there!
When x is equal to 5, 4x and 15+x have the same value because 4*5= 20 and 15+5 = 20.
4x and 15+x are not equivalent expressions because they cannot be simplified to create the same expression nor will they produce the same answer every time.

determine the slope between the two points
(-2,9) and (1,6) PLS I WILL GIVE BRAINIEST!!
Answer:
The slope between the two given point is -1
Step-by-step explanation:
The rule of the slope between two points (x1, y1) and (x2, y2) is
m = [tex]\frac{y2-y1}{x2-x1}[/tex]
Let us use this rule to solve the question
∵ The given points are (-2, 9) and (1, 6)
∴ x1 = -2 and y1 = 9
∴ x2 = 1 and y2 = 6
→ Substitute them in the rule of the slope above
∵ m = [tex]\frac{6-9}{1--2}[/tex]
→ Remember (-)(-) = (+)
∴ m = [tex]\frac{-3}{1+2}[/tex]
∴ m = [tex]\frac{-3}{3}[/tex]
→ Divide up by down
∴ m = -1
∴ The slope between the two given point is -1
