The parabola f(x) = 2x² - 5x + 1 has been D. The parabola is translated down 2 units.
What is a quadratic equaton?A quadratic equation is an algebraic expression in the form of variables and constants.
A quadratic equation has two roots as it's degree is two.
We know the graph of a quadratic equation ax² + bx + c is a parabola that opens upwards and is symmetrical about the y-axis.
Given, a parabola f(x) = 2x² - 5x + 3.
Now it is changed to f(x) = 2x² - 5x + 1 which also can be written as,
f(x) = 2x² - 5x + 3 - 2, So it has been translated 2 units down along the y-axis.

solve for d, s = 2d / t
s = 2d / t
Multiply both sides by t

which expression has the same value as 3y+2x
a. 3y+(-2x)
b.-2+3y
c.2x-(-3y)
d.-3y-2x
Answer:
Hey there!!
Your required answer is option C.
The reason is;
In option A when you simplify the signs, you will get it as 3y-2x.In option B it's totally not matching. In option C, when you simplify the signs, you will get as 2x + 3y {as( - )× (- )= (+)}.Option D is not matching.Therefore, the possible answer is option D.

If a=0 and b≠0, where will the graph of the complex number a+bi always lie?
Answer:
On the horizontal axis
Step-by-step explanation:
The complex number is represented by the complex plane or z-plane which is the representation geometrically of the real (number) axis and the imaginary (number) axis
When plotting complex numbers, the real part of the complex number is always plotted on the horizontal axis while the imaginary part is plotted on the vertical axis
The complex plane concept facilitates the description of complex numbers geometrically.

The error in this congruence statement is that we don't know if these are actually congruent.
Saying that the triangles "look the same" simply isn't enough. We do know that all three angles are the same, but the AAA (Angle Angle Angle) postulate only works for similar triangles.
Additionally, even if they were congruent, it would still be triangle ABC ≅ triangle FED, not triangle DEF.

Ms. Anderson made a New year's resolution to go on a diet and exercise more. On January 1st , she weighed 160 pounds. Two months later, she had dropped to 136 pounds. What was the percent of decrease in her weight?
Answer: 15%
Step-by-step explanation:
From the question, we are informed that Mrs Anderson weighed 160 pounds earlier and two months later, she had dropped to 136 pounds. To. Calculate the percent of decrease in her weight goes thus:
We've to find her decrease in weight first. This will be:
= 160 pounds - 136 pounds
= 24 pounds
Percentage decrease will now be:
= Change in weight/Original weight × 100
= 24/160 × 100
= 0.15 × 100
= 15%
The percent of decrease in her weight is 15%.

36. GEOMETRY Write an algebraic expression to
represent the area of the triangle. Then evaluate it to
find the area when h = 12 inches.
Answer:
108 in²
Step-by-step explanation:
Area of a triangle is given as ½*base*height
The base of the given triangle = h + 6
height = h
Algebraic expression for its area = [tex] \frac{1}{2}*(h + 6)*h = \frac{1}{2}(h^2 + 6h) = \frac{h^2 + 6h}{2} [/tex]
Evaluate the area if h is given as 12 inches.
Plug in the value of h into the algebraic expression:
[tex] \frac{h^2 + 6h}{2} = \frac{12^2 + 6(12)}{2} [/tex]
[tex] = \frac{144 + 72}{2} [/tex]
[tex] = \frac{216}{2} = 108 in^2 [/tex]

A carpenter and his assistant can do a piece of work in 3 days. If the carpenter himself could do thework alone in 5 days, how long would the assistant take to do the work alone?
Answer:
7 1/2 days
Step-by-step explanation:
The carpenter can do 1/5 of the work in 1 day. The assistant, who takes 'a' days to do the work, can do 1/a of the work in 1 day. Together, they can do 1/3 of the work in 1 day:
1/5 + 1/a = 1/3
1/a = 1/3 -1/5 = 2/15
a = 1/(2/15) = 15/2 = 7.5
The assistant takes 7.5 days to do the work alone.

The probability that a randomly selected customer who is on plan B uses the phone most often to text is 13/23
What is the probability?Probability refers to a possibility that deals with the occurrence of random events. The probability of all the events occurring need to be 1.
The formula of probability is defined as the ratio of a number of favorable outcomes to the total number of outcomes.
P(E) = Number of favorable outcomes / total number of outcomes
