What's substitution for y=4x-1, 2x+y=5
Answers
Step-by-step explanation:
y = 4x-1
2x+y = 5
2x+(4x-1) = 5
6x - 1 = 5
6x = 6
x = 1
Answer:
(1,3)
Step-by-step explanation:
Since we already have the variable to it self, we can substitute y=4x-1 into 2x+y=5.
So it would be 2x+(4x-1)=5
Remove the parentheses
Combine like terms
Move the constant to the right
Divide 6 on both sides to get the variable by it self.
x=1
Then we substitute x=1 into y=4x-1, so..
y=4(1)-1
y=4-1
y=3
So the answer would be (1,3).

Use these graphs to solve the simultaneous equations 5x-9y = -46
y = -2x
Answers
Answer:
(-2, 4)
Step-by-step explanation:
In the first equation substitute -2x for y, obtaining: 5x - 9(-2x) = -46
Then 5x + 18x = -46, or 23x = -46, resulting in x = -2
Since y = -2x, y = -2(-2) = 4
The solution is (-2, 4)
The value of x coming is -2 and the value of y=4 by plotting the equations 5x-9y=-46 and y=-2x.
What is a equation?
A statement that the values of two mathematical expressions are equal.
How to plot graph of an equation?
First we have to find the values of x and y as we can see in the figure1.
By plotting these points we can make graph of both the equations and the intersection point will be the solution of these equations.
Blue line is the line of the equation 5x-9y=-46 and the green line is the line of the equation y+2x=0

let b be base and h be height of the triangle
if each b and h is divided by 4
=> b/4 and h/4
using triangle area formula
1/2 x b/4 x h/4 = (bh)/32
the original triangle
=> 1/2 x b x h = (bh)/2
(bh)/32 x (something) = (bh)/2
that something is
(bh)/32/((bh)/2) = 16
Or
you could use the fact that the ratio of sides of those two triangles is 1 to 4 and because we are comparing the ratio of the area 1^2 to 4^2 which results in a 1 to 16 ratio which simply means you just have to multiply the smaller triangle by 16.

Step-by-step explanation:
The diagram shows a right angled triangle.
The length of the base of the triangle is 2 square root 3 cm. the length of the hypotenuse of the triangle is 6cm. The area of the triangle is A cm squared.
Show that A = k square root 2 giving the value of k.
Answers
Answer:
6 root 2
Step-by-step explanation:
Pythagous Therom
A^2 = B^2 + C^2
B^2 = C^2 - A^2
B^2 = 36 - (2 Root 3)^2
B^2 = 24
B = 2 root 6
Base x Height / 2 for area of Triangle
2 root 3 x root 24 = 12 root 2
12 root 2 / 2 = 6 root 2
The right triangle is the one where one of the angles is a right angle (90 degrees) or two of the sides are perpendicular.
Finding the value of k:The right-angled triangle is one where one of the angles is equal to 90°. The sum of the other 2 aspects is 90°. The perpendicular and the base of the triangle are indeed the sides that include the right angle. The hypotenuse, which would be the longest of the three sides, is the third side.In [tex]\Delta[/tex] ABC
h² = 6² -(2√3)²
h² = 36-2² × √3²
h² = 36- 4× 3
h² = 36- 12
h² = 24
h =√24
h = 2√6 cm
Area = [tex]\frac{1}{2}[/tex]× BC × h
= [tex]\frac{1}{2}[/tex] × 2√3 × 2√6
= 2√18
= 6√2
compare it with A= K√2 So K= 6

Elle and Layla are collecting data on student use of the school library. They collect data samples from the same population of students. After collecting their data, they each determine the standard deviation for their data sets. Layla's standard deviation is much larger than the standard deviation from Elle's data set.
Answers
Answer:
Layla's data set has a greater spread than Elle's data set
Eplanation:
I just got it right on the test I took..
The conclusion is Layla’s data set has more outliers or extreme values than Elle’s data set.
What do you mean by standard deviation?In statistics, Standard deviation is a measure of the variation of a set of values.
σ = standard deviation of population
N = number of observation of population
X = mean
μ = population mean
We are given that;
E and L collect data on library use from same students. L’s SD > E’s SD.
Now,
Since Elle and Layla collected data samples from the same population of students, we can assume that they have the same mean for their data sets. Hence, if Layla’s standard deviation is much larger than Elle’s standard deviation, it means that Layla’s data set has more variation or dispersion than Elle’s data set. In other words, Layla’s data set has more outliers or extreme values than Elle’s data set. This could be due to random sampling error or some other factor that influenced Layla’s data collection.
Therefore, by the standard deviation the answer will be Layla’s data set has more outliers or extreme values than Elle’s data set.

Which set of side lengths cannot form a triangle? (screen shot attached)
Answers
Answer:

Step-by-step explanation:
Based on the Triangle Inequality Theorem that states that the sum of any 2 sides of a triangle must be greater than the measure of the third side, we can find what set of lengths cannot form a triangle.
The only set that does not follow the theorem is the set with lengths 7in, 7in, and 15in. It does not follow the theorem because...

Determine the length of AC and DE, and the value of x.
Answers
Answer:
n = 16, AC = 60, DE = 30
Step-by-step explanation:
DE joins the midpoints of 2 sides of the triangle and is half the length of the third side, that is
DE = [tex]\frac{1}{2}[/tex] AC , substitute values
n + 14 = [tex]\frac{1}{2}[/tex] (3n + 12) ← multiply both sides by 2 to clear the fraction
2n + 28 = 3n + 12 ( subtract 2n from both sides )
28 = n + 12 ( subtract 12 from both sides )
16 = n
Then
AC = 3n + 12 = 3(16) + 12 = 48 + 12 = 60
DE = n + 14 = 16 + 14 = 30
