What is the value of x?
Answer:
x = 8
Step-by-step explanation:
Δ RST is equiangular since all 3 sides are congruent, thus
Each angle in the triangle is 60° , then
7x + 4 = 60 ( subtract 4 from both sides )
7x = 56 ( divide both sides by 7 )
x = 8
HELP PLEASE !!!
What is the vertex of this parabola?
y-5 = x^2?
====================================================
Work Shown:
y-5 = x^2
y = x^2 + 5 ... add 5 to both sides
y = 1x^2 + 5
y = 1(x-0)^2 + 5 ... x replaced with (x-0)
The equation is now in the form y = a(x-h)^2 + k
We have a = 1, h = 0, k = 5.
The vertex is (h,k) = (0,5)
The value of 'a' determines how vertically stretched or compressed the parabola is. Also, if a > 0, then the parabola opens upward; or if a < 0, then the parabola opens downward.

On Monday, Sarah has to meet her friend at the park after school The distance from her house to school is 2x+5 The distance from the school to the park is z If the total distance she was that day is 10x +9 how far is it from the park back to her
house?
Answer:
8x + 4 - z
Step-by-step explanation:
Given the following :
The distance from her house to school is 2x+5 The distance from the school to the park is z If the total distance she was that day is 10x +9 how far is it from the park back to her
Distance from house to school = 2x + 5
Distance from school to park = z
Total distance covered = 10x + 9
Distance from park to house =?
Total distance = (distance from house to school + distance from school to park + distance from park to house)
Let p = distance from park to house
10x + 9 = (2x + 5 + z + p)
10x + 9 - 2x - 5 - z = p
8x + 4 - z

Answer:
the answer is 300
Step-by-step explanation
there are 16 people so we divide that by the total number of students
400 divided by 16 = 25
since there are 12 right handed in each group we multpily it by 12
25 x 12 = 300

The ratios in an equivalent ratio table are 3:12, 4:16, and 5:20. If the first number in the ratio is 10, what is the second number? Justify your reasoning
Answer:
The second number is 40, because the first number is 5 times 2, so the second number is 20 times 2. Each ratio simplifies to be 1:4.

A and B are vertical angles. If mA=(7x-20° and mB =(6x-1)º, find the
measure of A.
Answer:
[tex]\angle A=113\textdegree[/tex]
Step-by-step explanation:
We know that ∠A and ∠B are vertical angles.
Remember that vertical angles have the same measure. So:
[tex]\angle A=\angle B[/tex]
Substitute them for their equations:
[tex]7x-20=6x-1[/tex]
Solve for x. Add 20 to both sides:
[tex]7x=6x+19[/tex]
Subtract 6x from both sides. So, the value of x is:
[tex]x=19[/tex]
To find ∠A, we can use its equation again:
[tex]\angle A=7x-20[/tex]
Substitute 19 for 7:
[tex]\angle A=7(19)-20[/tex]
Multiply and subtract:
[tex]\angle A=133-20=113\textdegree[/tex]
So, the value of ∠A is 113°.
And we're done!

A student did an experiment to determine the number of letters recognized on an eye chart to see if it was affected by distance. What is the independent and dependent variable in this experiment?
Answer:
Independent variable: distance
Dependent variable: number of letters recognized on an eye chart
Step-by-step explanation:
Independent variables are stand-alone. This means that it does not depend on another variable but affects the dependent variable.
Dependent variables are dependent on another variable. When the independent variable changes, dependent variables are changed.
Since the hypothesis is that the distance affects the number of letters recognized,
the distance causes a change in the number of letters recognized not the other way around.
Thus, the dependent variable is the number of letters recognized on the eye chart while the independent variable is the distance.

x and y
