Answer:
Ok, we know that we have a parabola (a quadratic equation) that is concave down.
This means that the "arms" of the graph will go down, then, the vertex is the maximum of the parabola.
Now we know that the vertex (again, the maximum) is on the third quadrant, this quadrant is on the negative region of x and on the negative region of y.
So, if from this point the arms of the parabola go down, then the arms will never intersect the x-axis.
So we do not have x-axis intercepts, which means that this parabola as no real roots.
And a parabola has always a y-intercept, but we have no enough information to conclude which is the y-intercept.
Ed's birthday is less than 16 days
away. Ann writes the inequality
d< 16, where d equals the number
of days, to represent this. Is Ann
correct? Explain.
Answer: Yes
Step-by-step explanation:
From the question, we are informed that Ed's birthday is less than 16 days
away and that Ann writes the inequality
d< 16, where d equals the number
of days, to represent this.
The inequality d < 16 is correct as it explains that the number of days left is less than 16.
Answer:
Ann is correct because d is less than 16.
Step-by-step explanation:
Ed's Birthday is *less than 16* days away so d<16
please and thank you
The answer is D. Y = 63 + 2 = 65
The given equation is y = x + 2, the height is given as 63. The height is the x value so you would replace x in the equation with 63 and solve for y.
The lengths of two line segments are shown. Use the ruler provided to measure the length of a third line segment to the nearest 12 inches. Which statement is true about these e three-line segments?
Answer:
These line segments can form a triangle, because the longest side of the triangle can be exactly 4 inches long.

Solve the simultaneous equations
4x + 5y = 9
4x - 2y = 2
Answer:
x = 1 and y = 1
Step-by-step explanation:
Let's solve your system by substitution.
4x + 5y = 9 ; 4x − 2y = 2
- Solve 4x + 5y = 9 for x:
4x + 5y = 9
4x + 5y + − 5y = 9 + − 5y (Add -5y to both sides)
4x = − 5y + 9
[tex]\frac{4}{x} = \frac{- 5y + 9}{4}[/tex]
[tex]x = \frac{- 5}{4} y + \frac{9}{4}[/tex]
Then Substitute [tex]\frac{- 5}{4} y + \frac{9}{4}[/tex] for x in 4x - 2y = 2
4x − 2y = 2
4([tex]\frac{- 5}{4} y + \frac{9}{4}[/tex]) − 2y = 2
− 7y + 9 = 2 (Simplify both sides of the equation)
− 7y + 9 + − 9 = 2 + − 9 (Add -9 to both sides)
− 7y = − 7
[tex]\frac{- 7y}{- 7} = \frac{- 7}{- 7}[/tex] (Divide both sides by -7)
y = 1
Substitute 1 for y in x = [tex]\frac{- 5}{4} y + \frac{9}{4}[/tex]
[tex]x = \frac{- 5}{4} y + \frac{9}{4}[/tex]
[tex]x = \frac{- 5}{4} (1) + \frac{9}{4}[/tex]
x = 1
So, x = 1 and y = 1

Of the 645 students in the freshman class, 85 are left-handed. About what percentage of the students are left-handed? Round to the nearest tenth.
About % of the freshman class are left-handed.
Answer:
About 13% of the freshman class are left-handed
Step-by-step explanation:
To find the percentage of a whole you need to divide the part by the whole number (85/645 = 0.1316), then you round to the nearest tenth (0.13) and change it into a percentage by moving the decimal point 2 numbers to the right. (13%)

PLEASE HELP!!!!!! PLEASE WILL MARK BRAIN FOR FIRST AND RIGHT ANSWER!!!
Answer:
yes
Step-by-step explanation:
Answer:
No
Step-by-step explanation:
All you need to do is solve for x and y because the intersection of both lines will only have one intersection.
since both equations are equal to y then you can set them equal to each other:
7x+8=x+1
6x=-7
x=-7/6
then inset back into y=x+1
y=-7/6+1
y=1/6
so that is the only point of intersection of the lines and it cannot be (3,8)

Answer for 2y + 4/x = 10
Answer:
Y = 5 - 2/x
Step-by-step explanation:
Answer:
x=2
Step-by-step explanation:
You want to isolate x so first, you have to multiply the whole equation by 1/4 so it will look like 1/4(2y+4/x=10). Simplify this to get 1/2y+x=5/2. You want to isolate x, so you have to subtract 1/2 from each side, this will make the equation x=5/2-1/2. Simplify this to get x=4/2 which can also be simplified to x=2. Therefore, the answer is x=2

What is the equation of the line that passes through the point (-4, 2) and has a
slope of 1/4?
Answer:
y = (1/4)x + 3
Step-by-step explanation:
I have put my answer in slope-intercept form as that is usually the most common. Inputing the slope as "m" into the equation "y=mx+b" and substituting the x and y coordinates given to find b gives the equation "2=(1/4)(-4)+b" By solving this we get "b=3" to finish the equation.
Answer:
y=1/4x+3
Step-by-step explanation:
y-2=1/4(x-(-4))
y-2=1/4(x+4)
y-2=1/4x+1
y=1/4x+1+2
y=1/4x+3

what is the equation of the line?
Answer:
x=3
Step-by-step explanation:
the x axis is going across by 2 and the number in between 2 and 4 is 3 and the line is going through the x axis hence the equation of the line is x=3
Answer:
[tex]x=3[/tex]
Step-by-step explanation:
Normally, linear equations would be written in slope-intercept form, [tex]y=mx+b[/tex], where [tex]m[/tex] is the slope and [tex]b[/tex] is the y-intercept (the value of y when the line crosses the y-axis). However, linear equations for horizontal or vertical lines are organized differently.
Here, we're given a vertical line. Vertical lines are written like [tex]x=d[/tex], where [tex]d[/tex] is the x-intercept, or the value of x when the line crosses the x-axis.
From the graph, we can tell that the x-intercept is 3. Therefore, our equation would be [tex]x=3[/tex].
