Dionna rode her skateboard at a speed of 10 miles per hour. Which statement is correct? *
If she covered 2.5 miles, she rode for 4 hours.
If she covered 2.5 miles, she rode for 0.25 hours.
If she covered 4 miles, she rode for 0.25 hours.
If she covered 4 miles, she rode for 4 hours.
Answer: A
Step-by-step explanation:
Because if she rode 10 mph means that she would ride 2.5 miles in 0.25 hours because if you divide 10 by 2.5 then you would get 0.25.

Answer:
B. 3x + y = 4
Step-by-step explanation:
y = -3x + 4
Check:
3x + y = 4
-3x -3x
y = -3x + 4
Answer:
It is B
Step-by-step explanation:
This is because if you use the point (1,1) for example then both x and y are 1.
1 X 3 = 3 and 3 + 1 = 4.
a portion of the quadratic formula proof is shown. fill in the missing reason.
ax^2+bx+c=0 —— Given
ax^2+bx=-c ——subtract c from both sides of the equation
x^2+b/a x=-c/a —— divide both sides of the equation by a
x^2+ b/a x+(b/2a)^2=-c/a+(b/2a)^2 —— complete the square and add (b/2a)^2 to both sides.
x^2+ b/a x+(b/2a)^2=-c/a+b^2/4a^2 —— square (b/2a) on the right side of the equation.
x^2+ b/a x+(b/2a)^2=-4ac/4a+b^2/4a^2—— find a common denominator on the right side of the equation.
x^2+ b/a x+(b/2a)^2=b^2-4ac/4a^2 —— ?????
A-multiply the fractions together on the right side of the equation
B- subtract 4ac on the right side of the equation
C- add 4ac to both sides of the equation

Which inequality is represented by this graph?
5+
(0,1)
(3,0)
A. ys-3x+1
B. y>-*x+1
C. 72-3x+1
D. y< -1x+1
The inequality is represented by the given graph is y ≤ -x/3+1.
The correct option is B.
What is inequality?An inequality is a relation that compares two numbers or other mathematical expressions in an unequal way. The majority of the time, size comparisons between two numbers on the number line are made.
We have,
A graph of an inequality, passing by (0, 1) and (3, 0).
A and D are eliminated since the line is solid.
C is disregarded because the line is shaded below as well.
Then, the inequality will be y ≤ -x/3+1
Hence, the inequality is represented by the given graph is y ≤ -x/3+1.

Step-by-step explanation:
Before her hike, Lara filled her water bottle with 4 cups of water. During the hike, she drank about 10 fluid ounces every hour. Afterward, she had about 12 fluid ounces left. How many hours did she hike?
Answer:
Lara hiked for 2 hours.
Step-by-step explanation:
1 cup = 8 ounces
4 cups = 32 ounces
32 - 10h = 12
10h = 20
h = 2
Lara hiked for 2 hours.
A cup contains 8 fluid ounces so the total number of ounces that Lara had before the hike was:
= Number of cups x fluid ounces per cup
= 4 x 8
= 32 fluid ounces
After the hike, Lara was left with 12 fluid ounces which means that she consumed:
= 32 - 12
= 20 fluid ounces
She drank 10 fluid ounces per hour so the total number of hours she hiked were:
= Number of fluid ounces consumed / Fluid ounces per hour
= 20 / 10
= 2 hours

Slope-Intercept Form: y = mx + b
m - slope b - y-interceptParallel Lines have the same slope but different y-intercepts.
Step-by-step explanation:
Step 1: Define
y = 2x + 1
Step 2: Break function
Slope m = 2
y-intercept = 1
Step 3: Set up parallel line
y = 2x + b
8 = 2(6) + b
8 = 12 + b
b = -4
y = 2x - 4
Answer:
y = 2x - 4
Step-by-step explanation:
y - y1 = m(x - x1)
y - 8 = 2(x - 6)
y - 8 = 2x - 12
+ 12 + 12
y + 4 = 2x
- 4 - 4
y = 2x - 4 ------- formula for slope-intercept form: y = mx + b

Please just give me a good explanation on how to reflect the x-axis and y-axis so I can learn it on my own as well as answering the question in the picture.
Answer:
Alright! BTW, the answer to the question is D :)
Step-by-step explanation:
Reflecting across the x-axis, the x-coordinate ALWAYS remains the same, but the y-coordinate is transformed into its opposite. If you forget this, fold along the x line, and you should be able to figure it out. Reflecting across the y-axis, the y-coordinate ALWAYS remains the same, but the x-coordinate is transformed into its opposite. If you forget this, fold along the y line, and you should be able to figure it out.

Integers were used in the 15th century by European traders to label barrels of grain or flour. For example, a barrel that was 1 pound too heavy was labeled +1, and a barrel that was 1 pound too light was labeled –1.
A trader checked twenty 50-pound barrels and found the labels to be: five –3s, nine –5s, two +4s, and four –8s. Find the actual total weight of the barrels.

57 is greater than x - 8
This is an inequality.
This is what the statement should look like: [tex]57 > x - 8[/tex]
Now, you can actually "properly" reverse these meaning the equality sign changes too. So basically you can mirror them.
The "mirrored" inequality expression would look like this: [tex]x - 8 < 57[/tex]
Now just like normal algebra, you can transpose these terms from 1 side to another and so, -8 would transpose to the right hand side and the operation would be the inverse or in this case, addition. The expression would look something like this: [tex]x < 57 + 8[/tex]
Add them up and you get: [tex]x < 65[/tex] :D
