Find the gradient of the line segment between the points (4,6) and (8,14).
Let a = (x1,y1) = (4,6) and b = (x2,y2) = (8,14)
Then, since the formula of the gradient (or Slope), given two points a and b is :
m = (y2 - y1) / (x2-x1) = (14 - 6) / (8 - 4) = 8 / 4 = 2
Then we know that the gradient is m = 2

Martin is sewing costumes for the school play. He needs 1/3
yard of ribbon for each costume. He has 12 3/4 yards of
ribbon left. How many costumes can he finish making?
Answer:
simple convert to improper to subtract
51/4 turn to a common denominator
so multiply by 3
153/12. 4/12
then just divide 153 by 12 = 12.75* 3 bc 3 costumes are one yard and you get 38.25 costumes or 38 bc you cant have .25 of a costume
The no. of costumes Martin can make is 38.
It is given that 1/3 yards of Ribbon is needed for each costume and [tex]12\frac{3}{4}[/tex] yards of Ribbon is left.
We have to find out the no. of costumes which Martin can make.
What is algebra ?
Algebra is the branch that deals with various symbols and the arithmetic operations and the symbols are called variables.
As per the question ;
Ribbon needed for each costume = 1/3 yards
Ribbon left = [tex]12\frac{3}{4}[/tex] yards
Let's assume no. of costumes Martin can make is x.
The ribbon needed for x costumes will be ;
= [tex]\frac{1}{3}[/tex] × x
= [tex]\frac{x}{3}[/tex] yards
So ;
The no. of costumes will be ;
[tex]\frac{x}{3}[/tex] yards = [tex]12\frac{3}{4}[/tex] yards
[tex]\frac{x}{3}[/tex] yards = [tex]\frac{51}{4}[/tex] yards
or
4x = 51 × 3
or
x = [tex]\frac{51 * 3}{4}[/tex]
x = [tex]\frac{153}{4}[/tex]
or
x ≈ 38
Thus , the no. of costumes Martin can make is 38.

Answer:
x=6.54138
x=0.458619
Step-by-step explanation:
using the Quadratic Formula where
a = 1, b = -7, and c = 3
x=−b±[tex]\sqrt{b^{2} -4ac}[/tex]/2a
x=−(−7)±√[(−7)2−4(1)(3)]/2(2)
x=7±√(49−12)/2
x=7±√37/2
The discriminant b2−4ac>0
so, there are two real roots.
Cannot Simplify the Radical:
x=[tex]\frac{7+-\\\sqrt{37} }{2}[/tex]
which becomes
x=6.54138
x=0.458619

I've been at a loss at how to do this one for a while. Someone, please help? No links, no spam. If you don't know the answer, then don't answer.
Answer:
12.72 m
Step-by-step explanation:
You're going to use the left side from the middle of AD up to point A. You see that's the same as a radius, so its length is 4.5. Then you can use the Pythagorean theorem to find the hypotenuse, the blue line from X to A.
(4.5)^2+(4.5)^2=x^2
40.5=x^2
x=6.36
and AC is two of the line you just figured out so 6.36x2=12.72m

Write an equation for each translation of y = |x|.
15.5 units left
A. y = | x | – 15.5
B. y = | x + 15.5 |
C. y = | x – 15.5 |
D. y = | x | + 15.5
Answer:
B. y = | x + 15.5 |
Step-by-step explanation:
The + inside the absolute value equation really means -.
So there is a horizontal shift of 15.5 units left.
Answer:
B. y = | x + 15.5 |
Step-by-step explanation:
Given : y= |x|.
To find : Write an equation for each translation of y= |x|. 15.5 units left .
Solution : We have given that y= |x|.
By the translation rule :if function transformed to f(x ) →→→ f(x +h) Then graph of the function would shift h units left.
For translation 15.5 unit left we need to add 15.5 in function y= |x|.
y = | x + 15.5 |
Therefore, y = | x + 15.5 |.

the yellow T-shirt cost as the blue T-shirt?
Draw a bar diagram and write and solve
an equation.
Yellow shirt $24
Blue shirt $8
The bar diagram is attached below. As we can see, the price of a yellow T-shirt is as three times as the price of a blue T-shirt. Hence, we can construct the following equation to determine the ratio between both prices:
[tex]y = r\cdot x[/tex] (1)
Where:
[tex]x[/tex] - Price of blue T-shirt, in monetary units.[tex]y[/tex] - Price of the yellow T-shirt, in monetary units.[tex]r[/tex] - Price ratio, no unit.If we know that [tex]x = 8[/tex] and [tex]y = 24[/tex], then the price ratio is:
[tex]r = \frac{y}{x}[/tex]
[tex]r = 3[/tex]
The price of the yellow T-shirt is as three times as the price of the blue T-shirt.

Two sides of a triangle are 11 can and 14 cm what are all the possible values for the length of the third side
Answer:
Step-by-step explanation:
The third side is thus, less than 14 + 11 = 25 cm. The side cannot be less than the difference of the two sides. Thus, the third side has to be more than 14 - 11 = 3 cm. So, the length of the third side could be any length greater than 3 cm and less than 25 cm.

Malik's average pace was 5.5 minutes per mile.
What is a system of equations?A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.
Given; Malik uses an app on his phone to track how far he rides his bike. Yesterday, he biked a new trail in a total of 57.5 minutes, including a 2.5-minute water break. The app notified Malik that he rode 10 miles.
Now, This equation represents the situation.
Now, solve the equation for p;
10p+2.5 = 57.5
Subtract 2.5 from both sides;
10p = 55
Divide both sides by 10
p = 5.5
Therefore, Malik's average pace was 5.5 minutes per mile.
