Answer:
2x+3y=13 ------(1)
4x-y=-2 -----(2)
Multiply (1) by 2,
=> 4x + 6y = 26. ---(3)
Subtract (2) from (3),
4x - 4x + 6y + y= 26 + 2
7y = 28
y = 4
x = (13-3(4))/2
x = 1/2.

what is the answer to this? −1.2b−5.3≥1.9
Answer:
b≤−6
here u go
Answer:
b ≤ -6 ✅Step-by-step explanation:
To solve an inequality, we will solve just like a normal equation. The goal is to isolate b, so we can determine the set of values it can take on.
Step 1: Add 5.3We need to reverse the operation - 5.3, so we add 5.3.
-1.2b - 5.3 + 5.3 ≥ 1.9 + 5.3
-1.2b ≥ 7.2
Step 2: Divide by -1.2We need to reverse the multiplication that is multiplying b by -1.2, so we will divide. However, we must remember an important rule first.
Important: When we divide by a negative number in an inequality, we must reverse the inequality sign, so ≥ becomes ≤.
-1.2b / -1.2 ≥ 7.2 / -1.2
b ≤ -6 (remember to reverse the sign!)
Step 3: CheckWe now substitute our answer in and see if it is correct. We will use a number that is smaller than -6, for example, -8.
-1.2(-8) - 5.3 ≥ 1.9
9.6 - 5.3 ≥ 1.9
4.3 ≥ 1.9 ✅
We can check again with -6, since this and all numbers smaller than it should be a solution set.
-1.2(-6) - 5.3 ≥ 1.9
7.2 - 5.3 ≥ 1.9
1.9 ≥ 1.9 ✅

Answer:
Option (2) 1.5
Step-by-step explanation:
Rule for the dilation of an image by a scale factor is,
Scale factor = [tex]\frac{\text{Radius of image circle A'}}{\text{Radius of pre-image A}}=\frac{r'}{r}[/tex]
= [tex]\frac{(2\pi) r'}{(2\pi) r}[/tex]
= [tex]\frac{\text{Circumference of image}}{\text{Circumference of pre-image}}[/tex]
= [tex]\frac{10.5}{7}[/tex]
= 1.5
Therefore, scale factor was used to create a circle A' = 1.5

can anyone help me with these questions please? 5 + 2x = 19 and also 4x + 3 = 27
Answer:
x= 7
x=6
Step-by-step explanation:
5+2x=19
Subtract 5 from both sides
so...
2x=14
then divide by two to isolate the x
so..
x=7
4x+3=27
Subtract 3 from both sides
so...
4x=24
then divide by 4 to isolate the x
so....
x=6
Answer: x = 7
5 + 2x = 19
-5 2x = 14 -5
/2 x = 7 /2
Answer: x = 6
4x + 3 = 27
-3 4x = 24 -3

The 4th term of the geometric progression is a₄ = 24/5
What is Geometric Progression?A geometric progression is a sequence in which each term is derived by multiplying or dividing the preceding term by a fixed number called the common ratio.
The nth term of a GP is aₙ = arⁿ⁻¹
The general form of a GP is a, ar, ar2, ar3 and so on
Sum of first n terms of a GP is Sₙ = a(rⁿ-1) / ( r - 1 )
Given data ,
Let the GP be represented as A
Now , the value of A = -3/5, 6/5, -12/5 ...
Let the first term of the GP be a = -3/5
Let the second term of the GP be ar = 6/5
Now , the common ratio of the GP = second term / first term
Substituting the values in the equation , we get
The common ratio r = ( 6/5 ) / ( -3/5 )
The common ratio r = -2
Now , the 4th term of the GP is a₄ = ar³
Substituting the values in the equation , we get
a₄ = ( -3/5 ) ( -2 )³
a₄ = ( -3/5 ) ( -8 _
a₄ = 24/5
Hence , the 4th term of the GP is 24/5
