Answer:
x = (-2)y = 2Step-by-step explanation:
2x + 3y = 6________( 1 )
-3x + 5y = 10_______( 2 )
( 1 ) × 3 ---- 6x + 9y = 18_____( 3 )
( 2 ) × 2 ---- -6x + 10y = 20_____( 4 )
[tex](4) + (3) \\ 6x + 9y + ( - 6x + 10y) = 20 - 18 \\ 6x + 9y - 6x - 10y = 2 \\ y = 2[/tex]
y = 2 ,
[tex]2x + 3y = 6 \\ 2x + 3(2) = 2 \\ 2x + 6 = 2 \\ 2x = 2 - 6 \\ 2x = - 4 \\x = \frac{ - 4}{2} \\ x = ( - 2) \\ [/tex]

Please answer this big question nobody ever answers my questions im sad :(
Answer:
Step-by-step explanation:
1.
3,4,5 will make a triangle.
2.
sum of any sides > third side
difference of any two sides < third side
3+4=7>5
4+5=9>3
5+3=8>4
again
4-3=1<5
5-3=2<4
5-4=1<3
so it makes one triangle.
3.
3,4,8
4.
3+4=7 not >7
again
8-4 =4 not <3
so they do not make a triangle.
Find the sum.

( PLASE HELP ME) Solve the following equation.
5(x−4)=−10
Please provide both your answer AND your work. You will not receive full credit if you do not show your work for this question.
Answer:
x = 2
Step-by-step explanation:
5(x-4) =-10
Distribute 5 by multiplying x and -4 by 5
5x - 20 = -10
Add 20 to both sides
5x - 20 + 20 = -10 + 20
5x = 10
Divide both sides by 5
5x ÷ 5 = 10 ÷ 5
x = 2

the sales-tax rate in new york is 8 and 1/4%. how much city sales tax would be charged on a purchase of $428.86? what will be the total cost of the purchase
Answer:
$464.24095
Step-by-step explanation:
8 1/4% = NY sales-tax rate
8 1/4 % = .0825
428.86 x .0825 = 35.38095
428.86 + 35.38095 = $464.24095

divide inverse function 2x³+1
Answer: The Inverse Function goes the other way: So the inverse of: 2x+3 is: (y-3)/2. The inverse is usually shown by putting a little "-1" after the function name, like this: f -1(y) We say "f inverse of y". So, the inverse of f(x) = 2x+3 is written: f -1(y) = (y-3)/2.

A = (b1 + b2) h / 2
I'm so confused, and i need to solve for h.
Answer:
Step-by-step explanation:
Begin by multiplying both sides by 2
2*A = 2*(b1 + b2) * h/2 Cancel the 2s
2A = (b1 + b2 ) * h Divide both sides by (b1 + b2)
2A/(b1 + b2) = (b1 + b2)*h / (b1+b2) Cancel B1 + b2
2A/(b1 + b2) = h

If the measure of ∠3=(2y+20)∘ and the measure of ∠5=(210−4y)∘, what is the measure of ∠4 ?
Enter the correct answer in the box.
Answer:
∠4 = 110
Step-by-step explanation:
∠3 + ∠5 = 180 {Co-interior angles are supplementary}
2y + 20 + 210 - 4y = 180
2y - 4y + 20 + 210 = 180 {Combine like terms}
-2y + 230 = 180
Subtract 230 from both sides
-2y = 180 - 230
-2y = -50
Divide both sides by (-2)
y = -50/-2
y = 25
∠5 = 210 - 4y
= 210 - 4*25
= 210 - 100
∠5 = 110
∠4 = ∠5 {Alternate interior angles are equal}
∠ 4 = 110°
Answer:
Step-by-step explanation:
110

(4,-3),m=-1 in standard form
Answer:
Step-by-step explanation:
m = -1 ; ( 4 , -3)
y - y1 = m(x - x1)
y - (-3) = -1(x - 4)
y+ 3 = -x + 4
Add x to both side.
x +y + 3 = 0
Subtract 4 from both sides
x + y + 3 - 4 = 0
x +y - 1 = 0
Solve for t:
t + 7 = 21
A: t= 28
B: t= 14
C: t= -28
D: t= -14
t + 7 = 21
---Subtract 7 from both sides
t + 7 - 7 = 21 - 7
t = 14
Hope this helps!! :)
Answer:
B) t = 14

in the blanks.
Devon just became a personal trainer and is finalizing her pricing plans. One plan is to charg
$51 for the initial consultation and then $48 per session. Another plan is to charge $38 for
the consultation and $49 per session. Devon realizes that the two plans have the same cost
for a certain number of sessions. What is that cost? How many sessions is that?
The cost on either plan is $|
for
sessions.
Submit
Answer:
13 sessions
The cost for either plan: $675
Step-by-step explanation:
48x + 51 = 49x + 38
51 - 38 = 49x - 48x
13 = x
