The equation x2 = d has how many real solutions when d > 0?
Answer:
Two: [tex]\sqrt{d}[/tex] and [tex]\left(-\sqrt{d}\right)[/tex].
Step-by-step explanation:
The question is asking for the number of real numbers [tex]x[/tex] whose square is equal to [tex]d[/tex] (where [tex]d > 0[/tex].)
Naturally, the square root of [tex]d[/tex]: [tex]\sqrt{d}[/tex] would satisfy the requirement. [tex]\left(\sqrt{d}\right)^{2} = d[/tex].
However, keep in mind that [tex](x)^2[/tex] and [tex](-x)^{2}[/tex] have the same value. Therefore, if [tex]x =\sqrt{d}[/tex] would satisfy the equation, the opposite [tex]x = -\sqrt{d}[/tex] would also do.
Since [tex]d > 0[/tex], [tex]\sqrt{d}[/tex] and [tex]\left(-\sqrt{d}\right)[/tex] would both take real values.
Because [tex]d \ne 0[/tex], the value of [tex]\sqrt{d}[/tex] and [tex]\left(-\sqrt{d}\right)[/tex] would be distinct.
Hence, [tex]\sqrt{d}[/tex] and [tex]\left(-\sqrt{d}\right)[/tex] would correspond to the two real solutions of this equation.

Quadratic functions g(x) and h(x) are graphed on the same coordinate grid. The vertex of the graph of h(x) is 12 units above the vertex of the graph of g(x) .
Which pair of functions could have been used to create the graphs of g(x) and h(x)?
h(x)=(x+12)2 and g(x)=x2
h(x)=x2−12 and g(x)=x2
h(x)=x2+12 and g(x)=x2
h(x)=(x−12)2 and g(x)=x2
Answer:
h(x) = x^2 + 12 and g(x) = x^2
Step-by-step explanation:
In this case there is a positive, vertical translation of 12 units up.
The original g(x) = x^2 has its vertex at (0, 0), whereas h(x) has its vertex at (0, 12). The function h(x) is found by adding 12 to g(x) = x^2:
h(x) = x^2 + 12
The third answer choice is the correct one: h(x) = x^2 + 12 and g(x) = x^2

Answer:
128 in.^2?
Step-by-step explanation:
a rectangle is also a parallelogram, so find the area of the rectangles.
if it is a 30-60-90 triangle, 8 inches is x, and to find the sides, it is either (x)sqrt(3), or in this case, 2x, so 16x8= 128?

You’re supposed to use the points (4,-3) and (1,-4).
Slope = (difference of y-coordinates)/(difference of x-coordinates)
= (-3 - (-4))/(4 - 1) = 1/3
Answer:
slope = [tex]\frac{1}{3}[/tex]
Step-by-step explanation:
Calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (1, - 4) and (x₂, y₂ ) = (4, - 3) ← 2 points on the line
m = [tex]\frac{-3+4}{4-1}[/tex] = [tex]\frac{1}{3}[/tex]

Write an equation for a line that passes through the points (4, -3) and (-1,2). can someone help me how?
Answer:
Y=-x+1
Step-by-step explanation:
Answer:
y=-x+1
Step-by-step explanation:
to get this you use the point-slope formula
y-y1=m(x-x1) - plug in the coordinates and find the slope
y--3=-1(x-4) - change the sign and solve the parentheses
y+3=-x+4 - subtract 3 from both sides to get y by itself
y=-x+1

If x = 2 and y = 6 , evaluate the following expression: 2 ( x + y )
Answer:
Step-by-step explanation:
If x = 2 and y =6
Then
2 ( x+ y)
= 2 ( 2 + 6)
= 2 * 8
= 16
hope it helps :)
Answer:
16
Step-by-step explanation:
you will do 2 + 6 = 8
so it = 8
x=2
y=6
and than u will 8 x 2 = 16
the answer is = 16

The distance between Franklin City and Williamsville on a map is 3.2 inches. If the scale of the map is 1 inch = 15 miles, how many miles apart are the two cities?
Answer: 48 miles
Step-by-step explanation:
From the question, the distance between Franklin City and Williamsville on a map is 3.2 inches and the scale of the map is 1 inch = 15 miles.
The distance between the cities will be to multiply 3.2 by 15 to get the number of miles since 1 inch = 15 miles. This will be:
= 3.2 × 15 miles.
= 48 miles
The distance between Franklin City and Williamsville is 48 miles.
Answer:
48 Miles
Step-by-step explanation:
Good Luck
