Use these graphs to solve the simultaneous equations 5x-9y = -46
y = -2x
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

A rectangle has side lengths of (7.5a - 1.5b) cm, (3,5a + 4.5c) cm, and (6.5C + 2a) cm, and (8.50 -6.5c). Which expression represents the perimeter, in centimeters, of the
rectangle?
Answer:
Step-by-step explanation:
our lengths are:
7.5a-1.5b, 3.5a+4.5b, 6.5c+2a, 8.5-6.5c
P=7.5a+3.5a+2a-1.5b+4.5b+6.5c-6.5c+8.5=16a+3b+8.5

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.
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.

A different camera is selling for $7.50 off the regular price. It was discounted 15%. What was the original price of the camera?
A)$112.50
B)$75.00
C)$50.00
D)$45.00
Answer:
C) $50.00
Step-by-step explanation:
$7.50 is the 15% discount
1% of the original price would be ($7.50 / 15)=0.50
100% of the original price would be 100 x 0.50 = $50.00

Determine the length of AC and DE, and the value of x.
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

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.
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

Find a quadratic polynomial with integer coefficients which has x = 2/9, ± SQRT23/9 as its real zeros.
Answer:
The quadratic polynomial with integer coefficients is [tex]y = 81\cdot x^{2}-36\cdot x -19[/tex].
Step-by-step explanation:
Statement is incorrectly written. Correct form is described below:
Find a quadratic polynomial with integer coefficients which has the following real zeros: [tex]x = \frac{2}{9}\pm \frac{\sqrt{23}}{9}[/tex].
Let be [tex]r_{1} = \frac{2}{9}+\frac{\sqrt{23}}{9}[/tex] and [tex]r_{2} = \frac{2}{9}-\frac{\sqrt{23}}{9}[/tex] roots of the quadratic function. By Algebra we know that:
[tex]y = (x-r_{1})\cdot (x-r_{2}) = x^{2}-(r_{1}+r_{2})\cdot x +r_{1}\cdot r_{2}[/tex] (1)
Then, the quadratic polynomial is:
[tex]y = x^{2}-\frac{4}{9}\cdot x -\frac{19}{81}[/tex]
[tex]y = 81\cdot x^{2}-36\cdot x -19[/tex]
The quadratic polynomial with integer coefficients is [tex]y = 81\cdot x^{2}-36\cdot x -19[/tex].
The dimensions of a triangle are multiplied by 1S_4.Thearea of the smaller triangle can be found by multiplying the area of the original triangle by what number?
Answer: 16
Step-by-step explanation:
This explanation is all based on the fact that I read 1S_4 as 1/4 which is the most sensable assumption.
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.

(PLEASE ANSWER FOR BRAINILEST ASAP!!) (EXPLAIN!!) 3 boxes all way the same amount. All together they weigh 54.3 pounds. How much does 1 box weigh?
Answer:
Step-by-step explanation:
Let B = the weight of box B
Let 2B = the weight of box A
Let 2B + 30 = the weight of box C
B + 2B + 2B + 30 = 640
5B = 610
B = 122 pounds, weight of box B
2B = 2(122) = 244 pounds, weight of box A
2B + 30 = 2(122) + 30 = 274 pounds, weight of box C

Find L if A=LW, A=55 m2, and W=11 m.
Answer:44
Step-by-step explanation:subtract 55-11 which would equal L
Answer:
If you are multiplying L*W the answer would be 5 because w=11 ok and we don't know what L is but we know what A is and a=55 so you have to think what do we multiply 11 by to get 55 weel it's 5 so that's how we would know it's 5 IF you were multiplying. now if you just adding L+W that answer would be 44 because 55-11=44
