Answer:
Step-by-step explanation:
Let's solve your system by substitution.
5x+3y=35;2x+4y=28
Step: Solve 5x+3y=35 for x:
5x+3y=35
5x+3y+−3y=35+−3y(Add -3y to both sides)
5x=−3y+35
5x/ 5 = −3y+35/ 5 (Divide both sides by 5)
Step: Substitute −3/ 5 y+7 for x in 2x+4y=28:
2x+4y=28
2( −3/ 5 y+7)+4y=28
14/ 5 y+14=28 (Simplify both sides of the equation)
14/ 5 y+14+−14=28+−14 (Add -14 to both sides)
14/ 5 y=14
14/ 5 y/ 14/ 5 = 14/ 14/ 5
(Divide both sides by 14/5)
y=5
Step: Substitute 5 for y in x= −3/ 5 y+7:
x= −3/ 5 y+7
x= −3/ 5 (5)+7
x=4 (Simplify both sides of the equation)
Answer:
x=4 and y=5
Find the y intercept of the following line (-2,1) and (1, 2.5)
Answer:
2
Step-by-step explanation:
(-2 , 1) ; (1, 2.5)
Slope = [tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\[/tex]
[tex]\frac{2.5-1}{1-[-2]}\\\\= \frac{1.5}{1+2}\\\\=\frac{1.5}{3}\\\\= 0.5[/tex]
m =0.5
y -y1 =m(x -x1)
y - 1 = 0.5(x - [-2])
y - 1 = 0.5(x + 2)
y -1 = 0.5x + 0.5*2
y - 1 =0.5x + 1
y = 0.5x + 1 + 1
y = 0.5x + 2
y-intercept = 2

Pls help me with the question in the pic
Answer:
9/16
Step-by-step explanation:
the breadth of a rectangular handkerchief is 10 cm shorter than its length .if the perimeter of the handkerchief is 100cm. find its length and breadth..
plz help me
Step-by-step explanation:
Perimeter = 2(l+b)
2(x+x-10)=100cm
(x+x-10)= 100 divided by 2
(x+x-10)=50
2x-10=50
2x=50+10,60
x=60 divided by 2
X =30
Length = 30cm
Breadth= 30-10= 20cm
PLEASE MARK MY ANSWER AS THE BRAINILIEST!
Answer:
solution given:
length[l]=xcm(let)
breadth [b]=(x-10)cm
perimeter of rectangle [P]=100cm
we have
P=2[l+b]
100cm=2[x+x-10]
2x-10=[tex] \frac{100}{2} [/tex]
2x=50+10
x=[tex] \frac{60}{2} [/tex]
:.x=30cm
So
length[l]=x=30cm
breadth [b]=(x-10)=30-10=20cm

Answer:
Since they're asking you to find the missing sides "y" and "x" here's what you need to do....
Step-by-step explanation:
1) This is the 45-45-90 Triangle.
2) y = 20 becasue this is an isocelese triangle - meaning a triangle that has 2 sides of equal lengths!
3) in order to find x (which is the hyptoneus) you have to do
[tex]\sqrt{2}[/tex] * leg (use on of the legs)
= [tex]20\sqrt{2}[/tex]
also I think 45 degrees is there just to throw you off. And I'm pretty positive this is the correct answer, and i'm 100% sure that y = 20 is correct!

Actually Welcome to the Concept of the Average rate of change.
The average rate of change can be calculated by, finding the change of the two readings and getting a average between them.
here, for x =3 to x =5
1.) in the interval, x =3 to x = 4
the change is ==> 287 - 125 = 162
2.) in the interval, x = 4 to x=5
the change is ==> 549-287 = 262
Now the average ==> 162+262/2 ===> 212
Hence the average rate of change is 212

Step-by-step explanation:
Find zeros and y intercept of each function algebraically f(x)=x^3-10x^2+24x
Answer:
The zeros are 0, 4, 6.
The y-intercept is 0.
Step-by-step explanation:
f(x) = x^3 - 10x^2 + 24x
x^3 - 10x^2 + 24x = 0
x(x^2 - 10x + 24) = 0
x(x - 4)(x - 6) = 0
x = 0 or x - 4 = 0 or x - 6 = 0
x = 0 or x = 4 or x = 6
y-intercept:
Since x = 0 is a root, that means that the point (0, 0) is part of the function. That makes the y-intercept 0.
You can also solve for the y-intercept by letting x = 0 in the function and solving for f(0).
Let x = 0.
f(0) = 0^3 - 10(0^2) + 24(0)
f(0) = 0
y-intercept: 0

If the nth term of a number sequence is n^2 + 2,
find the first 3 terms and the 10th term
Answer:
The first three terms are [tex]3,6,11[/tex]
The 10th term is [tex]102[/tex]
Step-by-step explanation:
An ordered list of numbers is known as a sequence such that each number in the sequence is called a term.
The nth term is [tex]a_n=n^2+2[/tex].
To find the first 3 terms, put [tex]n=1,2,3[/tex]
[tex]a_1=1^2+2=1+2=3\\a_2=2^2+2=4+2=6\\a_3=3^2+2=9+2=11[/tex]
To find the 10th term, put [tex]n=10[/tex] in [tex]a_n=n^2+2[/tex]
[tex]a_{10} =(10)^2+2=100+2=102[/tex]

A tea shop brewed 8 7/8 pitchers of chamomile tea, of which it sold 2 3/5 pitchers. How many pitchers remained unsold?
Answer:6 11/40
Step-by-step explanation: You can change your units to decimals or to fractions of equal value. Decimals are easier for this so 8 7/8= 8.875 and 2 3/5 =2.6. Then subtract: 8.875-2.6= 6.275 You can now convert back to a fraction by simplifying the .275 into 11 by dividing by 25 and 1000 into 40 by dividing by 25. 6+11/40= 6 11/40 tea left
Answer:
6 11/40
Step-by-step explanation:
First you have to convert the fractions into improper fractions, where 8 7/8 would turn into 71/8 and 2 3/5 would turn into 13/5. Then you have to find a common denominator which would be 40, so you get 355/40 and 104/40. Then to find the remaining amount, you have to subtract 104/40 from the 355/40, so 355/40 - 104/40, which equals 251/40. This turns into 6 11/40, which can't be simplified any further. Hope this helps :)
if the point x,y is on the y-axis which of the following is true x=0 y=0
Hi there!
Answer:
x=0
How it works:
In coordinate planes, x always goes first. Then the y comes next. If x is 0, and y is also zero, none of those would be in the y axis place...
If the x is in 0 and the y is 1,2,3,4,5.... then the y axis would be in the y axis and x would just stay the same...
If the x is 1, then the y would be 0 which means that there would be nothing in the y axis.
Therefore, the answer is x=0..
