Y = 2x
X - Y = 10
Answers
Answer:
x=-10, y=-20
Step-by-step explanation:
first you substiture the y in the second equation with the first
x-2x=10
then solve
1x-2x=-1
-x=10
multiply both sides by a negative to make the varible a
positive
x=-10
now we substitue the x in the first equation with -10
y=2(-10)
y=-20

What is the distance between (2, 5) and (2,-5) on the coordinate plane
Answers
Answer:
10
Step-by-step explanation:
When you find the distance, you just add both of the numbers as if they were in absolute value 5+|-5|
so then since the x values are the same, you would go up/down 10 spaces on the Y-axis
Answer:
10 units
Step-by-step explanation:
Use the distance formula:
[tex]\sqrt{ (x_{2} - x_{1} )^2 -(y_{2} - y_{1} )^2[/tex]
Plug in values:
[tex]\sqrt{ (-5-5 )^2 -(2-2 )^2[/tex]
[tex]\sqrt 100[/tex]

Two friends, Sasha and Maria, are growing out their hair. They plan to cut it off at a certain
point and donate it to a charity that makes wigs for people with cancer. Sasha's hair is
already 10 centimeters long and grows at a constant rate of 3 centimeters per month. Maria's
hair is 36 centimeters and growing at a speed of 1 centimeter per month. If the girls get their
hair cut on a certain day, they will have exactly the same length to donate. How long will that
take? How long will their hair be?
In
months, both girls' hair will be
centimeters long,
Answers
Answer:
13 months, 49 cms
Explanation:
For Sasha, multiply 3 and 13 together for the growth per month. You should get 39, then add the 10 cm Sasha already has. The sum is 49.
For Maria, multiply 13 and 1 for the growth per month. You should get 13, then add the 36 Maria already has. The sum is also 49.

A line perpendicular to QR is given by the equation 5x + 2y = 9
Find an expression for b in terms of a. W
Answers
Answer:
b= (2a+11)/5
Step-by-step explanation:
5x + 2y = 9
2y=9-5x
y= 9/2 - 5x/2
slope, m1= -5/2
for perpendicularity, m1 × m2 = -1
slope for QR= m2=
[tex] = - 1 \div \frac{ - 5}{2} = - 1 \times \frac{2}{ - 5} = \frac{ - 2}{ - 5} = \frac{2}{5} [/tex]
m2 is 2/5
[tex]qr = \frac{b - 3}{a - 2} [/tex]
[tex] \frac{2}{5} = \frac{b - 3}{a - 2} [/tex]
5(b-3)=2(a-2)
5b-15=2a-4
5b=2a-4+15
5b= 2a+11
[tex]b = \frac{2a + 11}{5} [/tex]
An expression for b in terms of a is b = (2a + 11)/5.
What are lines and their slopes?We know lines have various types of equations, the general type is
Ax + By + c = 0, and the equation of a line in slope-intercept form is
y = mx + b.
Where slope = m and b = y-intercept.
the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.
Given an equation of a line 5x + 2y = 9 ⇒ 2y = - 5x + 9 ⇒ y = (-5/2)x + 9/2.
So, the slope of the line parallel to QR is the slope negative reciprocal of (-5/2) which is (2/5).
We know slope m = (b - 3)/(a - 2).
∴ (2/5) = (b - 3).(a - 2).
2(a - 2) = 5(b - 3).
2a - 4 = 5b - 15.
2a + 11 = 5b.
b = (2a + 11)/5.
