Which of the following inequalities matches the graph? (1 point)
x<2
y> 2
y<2
x>2
Answer:
The inequality [tex]x>2[/tex] matches the graph.
Step-by-step explanation:
The graph shows that the shaded graph is headingtowards the +ve ∞ from the [tex]x > 2[/tex].
As the graph involves a dotted line, meaning the inequality must
contain < or > inequality.
The dotted line illustrates that [tex]x=2[/tex] will not be in the solution of the inequality.
so (2, ∞) is the interval of the domain of the inequality will be:
Therefore, inequality [tex]x>2[/tex] matches the graph.

2(4x + 3) = 10x - 2
Answer:
x = 4
Step-by-step explanation:
2(4x + 3) = 10x - 2
2 × 4x + 2 × 3 = 10x - 2
8x + 6 = 10x - 2
8x - 10x = - 6 - 2
- 2x = - 8
2x = 8
x = 8/2
x = 4
-TheUnknownScientist
Answer:
x= 4
Step-by-step explanation:
we open brackets first
2(4x + 3) = 10x - 2
8x+6=10x-2
transpose
6+2= 10x-8x
8= 2x
x= 8/2

Is this graph a function
Answer:
No.
Step-by-step explanation:
If you perform the "vertical line test" you will see that if that line intersects more than once, it is not a function.
Inspect the graph to see if any vertical line drawn would intersect the curve more than once.
If there is any such line, the graph does not represent a function.
If no vertical line can intersect the curve more than once, the graph does represent a function.

2t + 2 = 20
2t = 18
Add 2 to both sides
Subtract 2 from both sides
Multiply both sides by 2
Divide both sides by 2
Apply the distributive property
Please tell me what t is too
Answer:
t = 18/2
= 9
Sorry only thing I know is this!!
The value of t from the given equation is 9.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
The given equation is 2t+2=20.
The solution of an equation is the set of all values that, when substituted for unknowns, make an equation true.
Now, 2t=18 (Subtract 2 on both the sides of an equation)
t=9 (Divide 2 on both the sides of an equation)
Therefore, the value of t from the given equation is 9.

Step-by-step explanation:
The length of a rectangle is four times its width.
If the perimeter of the rectangle is 90 yd, find its length and width.
Answer:
Length of rectangle = 36 yd and width of rectangle = 9 yd
Step-by-step explanation:
Let width of rectangle = w
Length of rectangle = 4w (four times the width)
Perimeter of rectangle = 90 yd
We need to find length and width of rectangle.
The formula used will be: [tex]Perimeter \ of \ rectangle=2(l+w)[/tex]
Where l is length and w is width
Putting values and finding length and width of rectangle
[tex]Perimeter \ of \ rectangle=2(l+w)\\90=2(4w+w)\\90=2(5w)\\90=10w\\w=\frac{90}{10}\\w=9[/tex]
So,width (w) of rectangle is w= 9 yd
Finding length of rectangle = 4w = 4*9 = 36 yd
So, length of rectangle = 36 yd and width of rectangle = 9 yd
An integer is 15 more than 2 times another. If the product of the two integers is -27, then find the integers
Answer:
The required integers are x=3 and y= -9
Step-by-step explanation:
Let one the integers be x and y
An integer is 15 more than 2 times another: x=15+2y
product of the two integers is -27: x*y=27
[tex]x=15+2y ---eq(1)\\x*y=-27----eq(2)[/tex]
Solving both equations to find values of x and y
Putting value of x from equation 1 in equation 2
[tex](15+2y)*y=-27\\15y+2y^2=-27\\Rearranging:\\2y^2+15y-27=0[/tex]
This can be solved using quadratic formula:
[tex]$y=\frac{-b\pm\sqrt{b^2-4ac}}{2a}$[/tex]
Putting values and finding factors
[tex]$y=\frac{-(15)\pm\sqrt{(15)^2-4(2)(-27)}}{2(2)}$\\$y=\frac{-(15)\pm\sqrt{225+216}}{4}$\\$y=\frac{-(15)\pm\sqrt{441}}{4}$\\$y=\frac{-(15)\pm21}{4}$\\$y=\frac{-(15)+21}{4} \ or \ y=\frac{-(15)-21}{4}$\\$y=\frac{6}{4} \ or \ y=\frac{-36}{4}$\\$y=\frac{3}{2} \ or \ y=-9$[/tex]
Since y is integer so, we consider only y= -9
The value of x will be:
[tex]x*y=-27\\x*(-9)=-27\\x=\frac{-27}{-9} \\x=3[/tex]
So, the value of x is x=3
The required integers are x=3 and y= -9
