HELP ASAP PLEASE
Answer:
y=1/2x-3
Step-by-step explanation:
I hope you meant slope of the line...
You can find the slope like this-
1/2x= how you move (so m for move)
-3 =where you begin (so b for begin)
So next time you find the slope, just ask yourself where you "begin" (where the line starts) and how you "move" (how the line moves)

the area of an isosceles triangle is 60 CM square and its base is 10 cm find the length of the equal sides
Step-by-step explanation:
Area = (1/2) *b*h
60 =(1/2)*10h
120 =10h
h=120/10
h= 12 cm
From the figure,
AB=BC(since the given triangle isosceles).
AE is perpendicular to BC.
BE =EC = 5cm ( since is AE bisects BC)
AB= h=12cm (height of the isosceles triangle)
Applying Pythagoras theorem in triangle ABE,
AB² = BE²+ AE²
AB² = 5²+12²
AB² = 169
AB =√169
AB= 13 cm
Hence AB=BC =13cm
Length of equal sides =13cm
Quadrilateral ABCD is a parallelogram. Determine the measure of _A.
OA) 96°
B) 78°
C) 52°
OD) 39°
Answer:
The measure of angle A is: m∠A = 96
Therefore, option A is true.
Step-by-step explanation:
Given
m∠C = 3x
m∠D = x+52
We know that the opposite angles of a parallelogram are also equal.
Determining m∠A
It is clear that A is the opposite angle of C.
i.e.
m∠A = m∠C
as m∠C = 3x
so m∠A = 3x
Determining m∠B
It is also clear that B is the opposite angle of D.
i.e.
m∠B = m∠D
as m∠D = x+52
so m∠B = x+52
We know that the sum of the angles of a parallelogram is 360°.
so
m∠A + m∠B + m∠C + m∠D = 360°
3x + (x+52) + 3x + (x+52) = 360°
Group like terms
[tex]3x+x+3x+x+52+52=360^{\circ \:}[/tex]
[tex]8x+104=360^{\circ \:}[/tex]
Subtract 104 on both sides
[tex]8x+104-104=360^{\circ \:}-104[/tex]
Simplify
[tex]8x=360^{\circ \:}-104[/tex]
[tex]8x=256[/tex]
Divide both sides by 8
[tex]\frac{8x}{8}=\frac{256}{8}[/tex]
Simplify
[tex]x=32[/tex]
Thus,
The measure of the angle A is:
m∠A = 3x
substitute x = 32
m∠A = 3(32)
m∠A = 96
Hence, the measure of angle A is: m∠A = 96
Therefore, option A is true.

A student is 7 years old. If you triple the teachers age and add the student's age the answer is 163. How old is the teacher?
Answer:
52
Step-by-step explanation:
We can write this out as an equation. Let's say that the teacher's age is x. Triple the teachers age plus the students age is 163, which can be written out as:
[tex]3x + 7 = 163[/tex]
We want to isolate the variable, so subtract 7 from both sides. This gives us:
[tex]3x = 156[/tex]
Finally, we divide both sides by 3, giving:
[tex]x=52[/tex]
So the teacher is 52 years old.
Hope this helps!
Answer: The teacher is 52.
Equation: 7+3t=163
Of 3,400 babies in a hospital, 1244 are boys and the rest are girls. What
percentage are girls?
9514 1404 393
Answer:
63.4% are girls
Step-by-step explanation:
The percentage that is boys is ...
1244/3400 × 100% = 36.6%
The remaining fraction is girls:
100% -36.6% = 63.4% . . . girls
The quotient of two algebraic expressions is a fractional expression, and the quotient of two polynomials is
Answer:
rational expression
Step-by-step explanation:
From the given information:
Since the quotient of two algebraic expressions seems to be a fractional expression,
Then the quotient of two polynomials;
For example:
[tex]\dfrac{1}{w}, \dfrac{2w-1}{w+1} \ or \ \dfrac{w^2-1}{w^2+1}[/tex] is a rational expression.
Kelly goes to the store and buys 9 boxes of cookies. The cost of each box is represented with the letter c. Which expression could you use to show how much money Kelly spent?
Answer:
9c because you don't know how much money Kelly actually spent so instead of doing 9 x the price of each box, you replace it with c, so it's 9c

what is the range of the following numbers
12, 20, 18, 25, 6
Answer:
The answer is 19
Step-by-step explanation:
Range is the difference between the largest and smallest number, so in this case the largest number is 25 and the smallest number is 6. Subtract 25 and 6 to get the range. So the answer would be, The range of the following numbers is 19.
Max was assigned to make 64 cookies for the bake sale. He made 125% of that number. 90% of the cookies he made were sold. How many of Max's cookies were left after the bake sale?
Answer: there are 8 cookies left
Step-by-step explanation:
Let's count how many cookies Max baked:
125% = 1.25
64 × 1.25 = 80
Let's count how many cookies were sold:
90% = 0.9
80 × 0.9 = 72
Leftover cookies:
80 - 72 = 8
