X-y=0 and 5x-2y=6 solve by elimination
Answer:
(2,2)
Step-by-step explanation:
first take x-y=0 and multiply it by -5 you will then get this
-5x+5y=0
5x-2y=6
add those together
3y=6
divide by 3
y=2
now plug 2 in for y
x-2=0
add 2 to both sides
x=2
Clear x.
5x-5 one
———= ——-
X-2 3
Answer:
5x-5 = 5(x−1)
X-23 = =x−23

perfume is sold in two diffrent sizes of bottle.
Answer: get the 2 perfums in the size 50ml
Step-by-step explanation:
80ml is 55 pound
50 ml is 45 pound
2nd is half of 45 pound which is 22.5
the 2 perfum in the size 50 ml with the special price is: 45 + 22.5 = 67.5 now per ml is 0.675 pound per ml i found the price per pound by dividing the ml by the price
for the 80ml the price per ml is 0.6875
Find the value of x. Your answer must be exact.
х
45° 18
Answer:
x = 63
Step-by-step explanation:
Simplifying
x + -18 = 45
Reorder the terms:
-18 + x = 45
Solving
-18 + x = 45
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '18' to each side of the equation.
-18 + 18 + x = 45 + 18
Combine like terms: -18 + 18 = 0
0 + x = 45 + 18
x = 45 + 18
Combine like terms: 45 + 18 = 63
x = 63
Simplifying
x = 63
3x^3+10x^2+7x divided by x+1

Exactly how long is PR?
P
8 cm
30°
6 cm
R
Answer:
PR = 10
Step-by-step explanation:
Pythagoras
hypotenus ² = base² + attitude ²
substitution ; PR² = 6²+8²
PR² = 100
PR = √100
So, PR = 10

The ratio of ebooks to novels is 4:5. if there are 32 ebooks how many novels are there?
================================================
Work Shown:
n = number of novels
(32 ebooks)/(n novels) = 4/5
32/n = 4/5
32*5 = n*4 ............ cross multiply
160 = 4n
4n = 160
n = 160/4 .............. dividing both sides by 4
n = 40
There are 40 novels.

Turn this equation into a sentence: 5x - 8 - 7
Answer:
5 times x minus 8 minus 7
Step-by-step explanation:
whenever you see an x right next to a number, it means that it's being multiplied for that number. For example: 2x mean 2 times x
This symbol - is a minus symbol. So when it's in front of a number, you say "minus" and then the number. For example: 4 - 3 means, Four minus three.

Find the possible values for m<1
Answer:
its the last choice
Step-by-step explanation:
you can't find the exact angle with the given info so option 1 is automatic out, m<1 is also clearly an obtuse angle so it will be larger then 90° so option 2 is out, and like I said before m<1 has to be larger then 90° so its not option 3 leaving only option 4

15(2x+2)=10(3x+4) equations with special cases
Answer:
no solution
Step-by-step explanation:
15(2x+2)=10(3x+4) Distribute.
30x+30=30x+40 Subtract 30x from both sides.
-30x -30x
30=40
30 does not equal 40, so there is no solution.

KEVI is an isosceles trapezoid.
If KN 10, NV = x, and IE = 2x+6,
what is the length of KV?
Answer:
14
Step-by-step explanation:
A trapezoid is a quadrilateral (has four sides and four angles) with a pair of opposite parallel sides. The pair of opposite parallel side is known as the base.
An isosceles trapezoid is a trapezoid with equal legs. The diagonals are also equal and both the upper and lower base angles are congruent.
From the question:
KV = IE = 2x + 6 (diagonals of a trapezoid are congruent)
From line segment addition postulate:
KV = KN + NV
substituting:
2x + 6 = 10 + x
2x + 6 - x = 10
x + 6 = 10
x = 10 - 6
x = 4
KV = 2x + 6
substituting x = 4:
KV = 2(4) + 6
KV = 14
Over what interval is f(x) negative? Justify your answer.
Answer in interval notation is (-3, 1)
This is the same as saying -3 < x < 1
=====================================================
Explanation:
Since y = f(x), this means we're looking for points on the red curve such that they have a negative y coordinate. Visually, we're looking for points that are below the horizontal x axis.
These points are shown in the diagram below. I've marked the section we're after in blue. This blue section spans from x = -3 to x = 1. We exclude both endpoints because each x value leads to f(x) = 0, but we want f(x) values smaller than zero.
