line r passes through on the same spot on the y axis as line z and also passes through the point (1,4). If the equation for line z is y= -2x + 3, what is the equation of line r
Answer:
r= x + 3
Step-by-step explanation:
They share the same y intercept so we can know the vertical shift up. The Y intercept of line z would be 3, so line r would share the intercept too. From this we can find that the slope would be one since moving one unit to the right also makes the equation go 1 unit up, from (0,3) to (1,4). This would mean that the equation of line r is r= x + 3

Sandra is choosing an Internet service provider.
• Smart Dot Company costs $12 per month plus $0.50 for each hour of Internet used.
• Communication Plus costs $2.50 for every hour of Internet used.
a. Create an equation to represent the cost of using the internet with each company. (2 marks) Let C represent the cost of using internet in any month.
Let t represent the number of hours used
Smart Dot, multiply the cost per hour by number of hours (t) and add to the monthly fee:
C = 0.50t + 12
Communication plus: Multiply the cost per hour by number of hours (t)
C = 2.50t

The area (A) of a triangle is calculated as
A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the perpendicular height )
Here b = 10 and h = 9 , then
A = [tex]\frac{1}{2}[/tex] × 10 × 9 = 5 × 9 = 45 in² → a
45
The area (A) of a parallelogram is
A = bh ( b is the base and h the perpendicular height )
Here b = 2 and h = 4 , then
A = 2 × 4 = 8 m² → a
46
A = bh ( with b = 4 and h = 10 )
A = 4 × 10 = 40 m² → d

Answer:
x = 16.4
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
sin theta = opp / hyp
sin 66 = 15/x
x sin 66 = 15
x = 15/sin 66
x=16.41954
Rounding to the nearest tenth
x = 16.4

Answer:
y= -6
x = 2
(2,-6)
Step-by-step explanation:
Indepedent variable = x = 2
Plug 2 in for x
f(2) = -5(2) + 4

why is 0.71875 a rational number
Answer:
Because it is terminating.
Step-by-step explanation:
0.71875 is rational because it is terminating (has a clear end). If it were a bunch of random numbers that never ended, then it would be irrational.
0.71875 is a rational number because it is a terminating and non-repeating decimal.
What are rational numbers and irrational numbers?Rational numbers are numbers that can be written as the ratio of two integers. For example: 1/2, 3/4, are rational numbers
Irrational numbers, any real number that cannot be expressed as the quotient of two integers—that is, p/q, where p and q are both integers. For example, there is no number among integers and fractions that equals Square root of√2.
Now,the given number is 0.71875
Here we see that digits after decimal 71875 stops,
hence the given number can be convert into fraction of the form a/b
So,
0.71875 = 71875/100000
So 0.71875 can be expressed in the form of a/b
Therefore 0.71875 is rational because it is a terminating and non-repeating decimal.

Can someone please help me with my maths question
Answer:
[tex]a. \ \dfrac{625 \cdot m}{27 \cdot n^{11}}[/tex]
[tex]b. \ \dfrac{x^{3 \cdot m - 2}}{y^{ 3 + n}}[/tex]
Step-by-step explanation:
The question relates with rules of indices
(a) The give expression is presented as follows;
[tex]\dfrac{m^3 \times \left (n^{-2} \right )^4 \times (5 \cdot m)^4}{\left (3 \cdot m^2 \cdot n \right )^3}[/tex]
By expanding the expression, we get;
[tex]\dfrac{m^3 \times n^{-8} \times 5^4 \times m^4}{\left 3^3 \times m^6 \times n^3}[/tex]
Collecting like terms gives;
[tex]\dfrac{m^{(3 + 4 - 6)} \times 5^4}{ 3^3 \times n^{3 + 8}} = \dfrac{625 \cdot m}{27 \cdot n^{11}}[/tex]
[tex]\dfrac{m^3 \times \left (n^{-2} \right )^4 \times (5 \cdot m)^4}{\left (3 \cdot m^2 \cdot n \right )^3}= \dfrac{625 \cdot m}{27 \cdot n^{11}}[/tex]
(b) The given expression is presented as follows;
[tex]x^{3 \cdot m + 2} \times \left (y^{n - 1} \right )^3 \div (x \cdot y^n)^4[/tex]
Therefore, we get;
[tex]x^{3 \cdot m + 2} \times \left (y^{n - 1} \right )^3 \times x^{-4} \times y^{-4 \cdot n}[/tex]
Collecting like terms gives;
[tex]x^{3 \cdot m + 2 - 4} \times \left (y^{3 \cdot n - 3 -4 \cdot n}} \right ) = x^{3 \cdot m - 2} \times \left (y^{ - 3 -n}} \right ) = x^{3 \cdot m - 2} \div \left (y^{ 3 + n}} \right )[/tex]
[tex]x^{3 \cdot m - 2} \div \left (y^{ 3 + n}} \right ) = \dfrac{x^{3 \cdot m - 2}}{y^{ 3 + n}}[/tex]
[tex]x^{3 \cdot m + 2} \times \left (y^{n - 1} \right )^3 \times x^{-4} \times y^{-4 \cdot n} =\dfrac{x^{3 \cdot m - 2}}{y^{ 3 + n}}[/tex]

10. What is the measure of angle y?
Answer:
50°
Step-by-step explanation:
Angles in a triangle always add up to 180°.
The square (bottom left of triangle) is a right angle and right angles always equal 90° and the other one is 40°, so you would add them up. This equals 130°.
To find y, you would have to do 180° minus 130° which is 50°.
