x – 7y = –11
5x + 2y = -18
Answer:
hope this help you
Step-by-step explanation:
Simplifying
X + -7y = -11
Solving
X + -7y = -11
Solving for variable 'X'.
Move all terms containing X to the left, all other terms to the right.
Add '7y' to each side of the equation.
X + -7y + 7y = -11 + 7y
Combine like terms: -7y + 7y = 0
X = -11 + 7y
Simplifying
X = -11 + 7y
------------------------------------------------------------------------------------------------------------
Solving
5x + 2y = -18
Solving for variable 'x'.
Add '-2y' to each side of the equation.
5x + 2y + -2y = -18 + -2y
Combine like terms: 2y + -2y = 0
5x = -18 + -2y
Divide each side by '5'.
x = -3.6 + -0.4y
Simplifying
x = -3.6 + -0.4y

If Triangle ABC ≈ Triangle DBE, find the value of x.
Answer:
x = 49
Step-by-step explanation:
The sum of angles in a triangle add up to 180°.
∠CBA = ∠EBD (Vertically opposite angles are equal)
= 52°
Since in the triangle DBE, you already know two of the angles, you can find ∠BDE which is equal to ∠CAB (x + 9)°.
∠BDE = 180° - 70° - 52°
= 58°
∠BDE = ∠CAB
= ∠(x + 9)°
= 58°
x + 9 = 58
x = 58 - 9
x = 49

A or B think it's A tho not sure
Answer:
B. -4
Step-by-step explanation:
The slope is -8/2 which is the same as -4.
Another way you could do it is down 4 and right 1. That would be -4/1 which is the same as -4.

Katy bought a $76 dress at 33% off and a $52 pair of shoes at 15% off. If
sales tax is 6.75% how much did she pay in total?
Answer:
101.54
Step-by-step explanation:
Answer:
$103.21
Step-by-step explanation:
33% of 76=$25.08 then 76-25.08=$50.92
12% of 52=$6.24 then 52-6.24=$45.76
50.92+45.76=$96.68
6.75% of 96.68=$6.525-->$6.53
96.68+6.53=($103.21)

What point is the intersection of the graphs of the lines 2 x - y = 3
and x + y = 3?
Answer:
(2, 1 )
Step-by-step explanation:
Given the 2 equations
2x - y = 3 → (1)
x + y = 3 → (2)
Rearrange (2) expressing y in terms of x by subtracting x from both sides
y = 3 - x → (3)
Substitute y = 3 - x into (1)
2x - (3 - x) = 3
2x - 3 + x = 3
3x - 3 = 3 ( add 3 to both sides )
3x = 6 ( divide both sides by 3 )
x = 2
substitute x = 2 into (3) for corresponding value of y
y = 3 - 2 = 1
Solution is (2, 1 )
3x-5y=22: y=-5x+32 solve for y

The function [tex]y= -x^{1/2}+5[/tex] has a domain of all real numbers.
Thus, option (D) is correct.
As, Domain is the input value of the function.
In the function [tex]y= -x^{1/2}+5[/tex] .
The square root is defined for all non-negative real numbers (including zero).
When we subtract this square root from 5, the resulting function has a domain of all real numbers.
In options A, B, and C, which involve fractional exponents or roots, option D does not have any restrictions on the values of x.
The function can be evaluated for any real number x, making its domain all real numbers.
Therefore, [tex]y= -x^{1/2}+5[/tex] , has a domain of all real numbers.
