Step-by-step explanation:
ok so for number 1 you first have to group the like terms therefore you will now have:
9r-4r+8-6
and now you calculate:
9r-4r=5r
8-6=2
so that means 5r-2 is simplied version for no.1
for number you 2 you first multiply why is inside the brackets by what is in the outside:
2(x+3y)
2x+6y (simplified version)
hope this helps! no problem
In ΔXYZ, z = 75 inches, x = 26 inches and ∠Y=135°. Find the length of y, to the nearest inch.
Answer:
95
Step-by-step explanation:
The length of the y of the triangle is y = 96 inches
What is Law of Cosines?The Law of Cosines is a mathematical formula used to find an unknown side or angle of a triangle, given the lengths of the other two sides and the angle opposite the unknown side. It is also known as the Cosine Rule.
The Law of Cosines states that for any triangle with sides a, b, and c and angle C opposite side c, the following equation is true:
c² = a² + b² - 2ab cos(C)
where cos(C) is the cosine of angle C. This formula can be rearranged to solve for any of the variables, depending on which values are known.
Given data ,
Let the triangle be represented as ΔXYZ
And , the measures of the sides of the triangle are
z = 75 inches
x = 26 inches
And , the measure of ∠Y = 135°
We can use the Law of Cosines to find the length of y, since we know two sides and the included angle of the triangle.
The Law of Cosines states that:
c² = a² + b² - 2ab cos(C)
where c is the side opposite angle C, and a and b are the other two sides.
In this case, we want to find the length of side y, which is opposite angle Y. So we can write:
y² = x² + z² - 2xz cos(Y)
Substituting in the given values, we get:
y² = 26² + 75² + 2(26)(75) cos(135°)
Simplifying, we get:
y² = 676 + 5625 - 2925√2
y² ≈ 9163
Taking the square root of both sides, we get:
y ≈ 95.76
Rounding to the nearest inch, we get:
y ≈ 96 inches
Hence , the length of y, to the nearest inch, is 96 inches

Help me please I will give brainly
Find the equation of the line.
Use exact numbers.
Y=“blank”x+ “blank”
Answer:
y=mx+b
b= y intercept
mx=slope
First lets find the y intercept = the y intercept is 3
Now lets find the slope = the slope is 3x because each time it goes 3 up it goes one right
So the answer is y=3x+3

A line has a slope of 6 and passes through the point (1,4). What is its equation in
slope-Intercept form?
Write your answer using Integers, proper fractions, and improper fractions in simplest form.
y-x-O
The slope intercept form of the line that passes through the point (1, 4) and has the slope 6 is y = 6 x - 2.
The point that the line passes through is:
(1, 4)
The slope of the line is:
m = 6
The slope intercept form of the line is:
y - y₁ = m (x - x₁)
Substitute the values in the equation, we get that:
y - 4 = 6 ( x - 1)
y - 4 = 6 x - 6
y = 6 x - 6 + 4
y = 6 x - 2
Therefore, we get that, the slope intercept form of the line that passes through the point (1, 4) and has the slope 6 is y = 6 x - 2.

Find f(-5) if f(x) = 5x + 11.
A) 4
B) 5
C) 6
Step-by-step explanation: Since f(x) = 5x + 11, we find f(-5)
by substituting a -5 in for the x in the function to get f(-5) = 5(-5) + 11.
Now just simplify the right side to get -25 + 11 or -14.
So f(-5) = -14.
Ana went to a book store and bought a pen and pencils and the total money she spent is $850 and a pen cost $150 and a pencil cost $100 what are all the possible purchases that she could have made.
Answer: So there are three ways...
$850=150(1)+100(7)
$850=150(3)+100(4)
$850=150(5)+100(1)
Step-by-step explanation:
The equation is 150x+100y=850 where x and y are any whole number of items that she was able to purchase with $850
So there are three ways...
$850=150(1)+100(7)
$850=150(3)+100(4)
$850=150(5)+100(1)
These are the purchases where x is pens and y is pencils

A container can hold three orange slices. If a company had twenty-six orange slices to put into containers, how many more slices would they need to fill up the last container?
Answer:
The last container needs one more slice to be filled up.
Step-by-step explanation:
From the question, we know that only 3 oranges can fit into a container.
However, the company has 26 oranges that need to be inside containers.
We can find out the number of containers that will be filled up completely and the remainder left.
We will do this by dividing the number of orange slices available by the number that can fit into a container.
This is 26 / 3 = 8 remainder 2
Therefore, 8 containers will be filled up, with only two oranges left in the last container.
Remember that each container needs up to 3 oranges to be filled up. Since the last container has only 2 orange slices in it, it needs one more slice to be filled up.

Group of answer choices
(t – 12)(t + 3)
(t – 6)(t – 6)
(t + 6)(t – 6)
(t – 12)(t – 3)
Answer:
(t + 6)(t - 6)
Step-by-step explanation:
(t - 6)(t + 6)
(t . t) + (t . (6) + ((-6) . t) + ((-6) . 6)
= t² - 6t + 6t - 36
= t² - 36
so,
t² - 36 = (t + 6)(t - 6)
