Answer:
(- 2, 1 ) and (1, 4 )
Step-by-step explanation:
Given the 2 equations
y = - x² + 5 → (1)
- x + y = 3 → (2)
Rearrange (2) expressing y in terms of x by adding x to both sides
y = x + 3 → (3)
Substitute y = x + 3 into (1)
x + 3 = - x² + 5 ( subtract - x² + 5 from both sides )
x² + x - 2 = 0 ← in standard form
(x + 2)(x - 1) = 0 ← in factored form
Equate each factor to zero and solve for x
x + 2 = 0 ⇒ x = - 2
x - 1 = 0 ⇒ x = 1
Substitute these values into (3) for corresponding values of y
x = - 2 : y = - 2 + 3 = 1 ⇒ (- 2, 1 )
x = 1 : y = 1 + 3 = 4 ⇒ (1, 4 )

Step-by-step explanation:
The framed wall art Modern is 20 and the total is 35 so unless you have to simplify this should be the answer
(−7x 2 −4)+(−7x 2 −6x−2)
-20
Explanation:
( − 7 ^ 2 − 4 ) + ( − 7 ^ 2 − 6 − 2 )
Eliminate the redundant parentheses, subtract the numbers which will get you, combine like terms, rearrange terms, then your solution is:
− 1 4 2 −6 −6
Figure that problem out then you will get -20.
Answer:
−14x^2 − 6x - 6
Step-by-step explanation:
(−7x 2 −4)+(−7x 2 −6x−2) should be written as (−7x^2 −4) + (−7x^2 −6x−2). The " ^ " symbol denotes exponentiation. 7x^2 means "7 times the square of x." We can immediately remove the parentheses, obtaining:
−7x^2 −4 −7x^2 − 6x − 2
Our next step is to combine like terms. For example, -7x^2 appears twice, with the same (negative) sign; summing these up results in -14x^2.
Immediately after doing that, we have:
−14x^2 −4 − 6x − 2
and need to combine the constants -4 and -2:
−14x^2 −6 − 6x
Finally, we write these terms in descending powers of x:
−14x^2 − 6x - 6

At a digital store, Jay paid a total of $31.35 for games and movie rental. He rented 6 games at $3.99 each game and 3 movies.
How much did Jay pay per movie?
$23.94
$3.48
$7.41
$2.47
Answer: 2.47
Step-by-step explanation:
6 times 3.99 is 23.94
31.24 minus 23.94 is 7.30
2.47 times 3 is 7.30

so
y=0
how do write an equation for this hyperbola from the foci?
Answer: Memorize the formula
Step-by-step explanation:
( x / a )^2 - ( y / b )^2 = 1
Where a and b are the semi-axis
The value of a is half the distance from points that cuts off x-axis, in this case
From -5 to 5 there is 10 so 5 is value of "a"
Value of b can find by the formula
c^2 = a^2 + b^2
Which c is the value of the point bold on the rightmost place in x axis. In this case its 13
13^2 = 5^2 + b^2
169 = 25 + b^2
b = 12
SO we got a = 5, b = 12
ANSWER: (x/5)^2 - (y/12)^2 = 1
A pair of jeans at American eagle cost $35.00. if the sales tax is 5% how much do the jeans cost total?
A $36.75
B $1.75
C $33.25
D $33.33
Answer:
$36.75
Step-by-step explanation:
If you take the original cost 35.00 and add 5% to it, you would get 36.75. If you think about it, it has to be above $35 since the sales tax would be more.
Answer: A - $36.75

Find the error for the proposed solution. Then correct the proposed solution.
2x + 18 = 16
2x = 34
2x 34
2 2
X = 17
Answer:
The error is in the second line.
x = -1
Step-by-step explanation:
When solving for "x", you are trying to isolate it, or move everything else to the other side. You may have learned that "what you do to one side, you do to the other" .
2x + 18 = 16
2x = 34 18 was added to the right side, but not to the other.
If you add 18 on both sides, then the equation would be:
2x + 36 = 34 "x" is not being isolated.
Instead, you should subtract 18 from 16.
Correct solutions steps:
2x + 18 = 16
2x + 18 - 18 = 16 - 18 Subtract 18 from both sides to cancel out 18
2x = -2
2x/2 = -2/2 Divide both sides by 2
x = -1 Final answer

The area of a rectangle is 38.5 square inches. The base of the rectangle is 4 inches. What is the height of rectangle?
Pls help me on this one. PLSSS :(
Answer:
The answer is 9.625
Step-by-step explanation:
So what you have is the area and the base of the rectangle. To find the height, just divide 4 into 38.5
38.5 / 4 = 9.625
To double check just multiple 9.625 by 4
9.625 x 4 = 38.5

Given the isosceles trapezoid EFGH and side length JL = 93 units. If the length of KN = (3x + 1) and MN = (5x - 4), what is the length of KM?
Answer:
KM=JL=93 units
or KM=KN + MN= 8x-3
Step-by-step explanation:
The value of length of KM can be equal to either JL or obtained by adding KN = (3x + 1) and MN = (5x - 4) depending on the diagram.
An isosceles trapezoid has non parallel sides congruent.
In the isosceles trapezoid the diagonals are also equal.
There is a pair of parallel lines in an isosceles trapezoid.
In the 1st figure trapezoid JL and KM are diagonals.
If we take the JM and KL to be the parallel lines then the opposite sides can be JK and LM
And N is the middle line or the mid segment.
In the figure 2
The value of length of KM is obtained by adding KN = (3x + 1) and MN = (5x - 4)
KM=KN + MN = (5x - 4) +(3x + 1)
KM=8x- 3
Triangle DAN is graphed on the set of axes below.
The vertices of ADAN have coordinates D(-6,-1),
A(6,3), and N(-3,10).
The area of the triangle DAN is 60 square units if the vertices of ΔDAN have coordinates D(-6,-1), A(6,3), and N(-3,10) option first is correct.
What is the triangle?The triangle can be defined as a three-sided polygon in geometry and it consists of three vertices and three edges. The sum of all the angles inside the triangle is 180°.
We have triangle DAN which is graphed on the set of axes.
The vertices of ΔADN have coordinates:
D(-6, -1), A(6, 3), and N(-3, 10)
We can find the area of the triangle using the coordinates of the triangle such as:
[tex]\rm Area \ of \ the \ triangle = \frac{1}{2} [x_1(y_2-y_3)+x_2(y_3-y_1)+x_3(y_1-y_2)][/tex]
Let's denote the coordinates N(-3, 10), D(-6, -1), andA(6, 3), and with
[tex]\rm (x_1, y_1), (x_2, y_2), \ and \ (x_3,y_3)[/tex] respectively.
Put these points in the above expression, we get:
[tex]\rm Area \ of \ the \ triangle = \frac{1}{2} [-3(-1-3)-6(3-10)+6(10-(-1))][/tex]
[tex]\rm Area \ of \ the \ triangle = \frac{1}{2} [-3(-4)-6(-7)+6(11)][/tex]
[tex]\rm Area \ of \ the \ triangle = \frac{1}{2} [12+42+66][/tex]
[tex]\rm Area \ of \ the \ triangle = \frac{1}{2} [120][/tex]
Area of the triangle = 60square units
Thus, the area of the triangle DAN is 60 square units if the vertices of ΔDAN have coordinates D(-6,-1), A(6,3), and N(-3,10) option first is correct.

Answer:
The answer is C
Explain:
Solve for x in the first equation.
Add 4y to both sides of the equation
3x=12+4y
12y-9x=36
Divide each term by 3 and simplify
X=4+4y/3
12y-9x=36
Replace all occurrences of x with 4+4y/3 in each equation.
-36=36
X=4+4y/3
Since -36=36 is not true, there is no solution
