Step-by-step explanation:
let the number be x
1/2(x) - 1/6(x) =10 -1/8(x)................this is the equation
1/12(x) + 1/8(x)=10
5/24(x)=10
cross multiply
5x= 240
x=240/5
x=48
Which parabola(s) have an axis of symmetry of x = -1
Answer:
b,c
Step-by-step explanation:
The axis of symmetry is along the vertex
a has a vertex at x=1
b has a vertex at x = -1
c has a vertex at x=-1
d has a vertex at x =2
Explanation:
Notice how the vertical line through the center of these parabolas is at x = -1. In other words, the vertical line cuts through -1 on the x axis. Reflecting one half of the parabola over this line will result in the other half.
find the midpoint between this pair of points (-4,10) and (14,0)
Explanation:
The x coordinates are -4 and 14. They add up to -4+14 = 10. Then this cuts in half to get 10/2 = 5. This is the x coordinate of the midpoint.
We'll follow this same idea for the y coordinates as well.
10+0 = 10 which cuts in half to 10/2 = 5, and this is the y coordinate of the midpoint.
Therefore, the midpoint is (5,5).
Coincidentally, the x and y coordinates are the same for the midpoint (both are 5). This won't always happen.

Please help……………………….
Let’s start with the easy part: half of the base is 3.
Therefore, 3 x h + 1 = 18
3 x h = 3h and 3 x 1 = 3
3h + 3 = 18
To solve these equations, you have to do the inverse. First you would need to minus 3:
3h = 15
3h is a simpler way of saying 3 x h, so the inverse would be a divide.
h = 5
A triangle has an area of 10 square feet. The height is 10 feet. What is the length of the base (in feet)?
Answer:
2 feet
Step-by-step explanation:
for area of a triangle it's (height times width) divided by 2, and 10 times 2 divided by 2 is 10
Answer:
Length of base of triangle = 2 feet
Step-by-step explanation:
Given:
Area of triangle = 10 square feet
Height of triangle = 10 feet
FInd
Length of base of triangle
Computation:
⇒ Area of triangle = (1/2)(Base)(Height)
⇒ 10 = (1/2)(Base)(10)
⇒ 10 = Base(5)
⇒ Length of base of triangle = 10 / 5
Length of base of triangle = 2 feet

O 5x + 3y = 18
O 5x - 3y = 30
O 5x - y = 30
O 5x + y = 18
Answer:
Hello the answer is 5x - y = 30!
Step-by-step explanation:
m = (0 (-5))/(6 - 3) = (0 + 5)/(3) = 5/3
y = mx + b
O = (5/3)(6) + b
O = (30/3) + b
O = 10 + b
-10 = b
3y = 5x - 30
3y + 30 = 5x
5x - 3y = 30

The diagram shows a square with side length 5cm.
The length of the diagonal is y cm.
Find the exact value of y.
Answer:
5sqrt2
Step-by-step explanation:
Using the pythagorean theorem, we get 5^2+5^2=c^2. C is the diagonal here. 25+25=c^2, c^2=50. c=sqrt50. Simplifying it, we get the diagonal as 5sqrt2.
Given the following information, give as complete a description of this figure as possible, including the measure of any sides and angles and any terms that can be used to describe the polygon.
Answer:
It's a square with four equal sides each side is 6cm. The angles at the four edges are all same have 90° between each two sides. You can calculate the area of the four triangles by using the formula 1/2 × hight × base. The hight will be 6 divided by 2 which is equal 3cm, and the base will be 6cm. So the area of each triangle is 1/2×3×6=9cm^2.

S is the centroid of the triangle. Find IT if ST =9
Answer:
27
Step-by-step explanation:
The centroid divide a median in two parts, with ratio 1/3 and 2/3.
In particular the part between the centroid and the point where the median touches the side is 1/3 of the median.
We can build this proportion:
ST : 1/3 = IT : 3/3
9 : 1/3 = IT : 1
IT = 9 * 3 = 27
