SHOW YOUR WORK WILL MARK BRAINLIEST IF YOU GET IT RIGHT solve by completing the square X²+6x-22=0
9514 1404 393
Answer:
x = -3±√31 ≈ {-8.568, +2.568}
Step-by-step explanation:
The usual steps are to ...
group the x-terms
(x² +6x) -22 = 0
add and subtract the square of half the x-coefficient
(x² +6x +(6/2)²) -22 -(6/2)² = 0
simplify to a binomial square
(x +3)² -31 = 0
Solve for x.
(x +3)² = 31
x +3 = ±√31
x = -3 ±√31 . . . . . solution to the quadratic

Slope intercept form
Given:
The equation of the parallel line is
[tex]y=-\dfrac{5}{2}x+7[/tex]
The required line passes through the point (-4,1).
To find:
The equation of line in slope slope intercept form.
Solution:
The slope intercept form of a linear function is
[tex]y=mx+b[/tex]
Where m is slope and b is y-intercept.
On comparing the equation [tex]y=-\dfrac{5}{2}x+7[/tex] with slope intercept form, we get
[tex]m=-\dfrac{5}{2}[/tex]
We know that the slopes of parallel lines are always same. So, the slope of the required line is [tex]m=-\dfrac{5}{2}[/tex].
The line passes through the point (-4,1) with slope [tex]m=-\dfrac{5}{2}[/tex]. So, the equation of line is
[tex]y-y_1=m(x-x_1)[/tex]
[tex]y-(1)=-\dfrac{5}{2}(x-(-4))[/tex]
[tex]y-1=-\dfrac{5}{2}(x+4)[/tex]
[tex]y-1=-\dfrac{5}{2}x-10[/tex]
Adding 1 on both sides, we get
[tex]y=-\dfrac{5}{2}x-10+1[/tex]
[tex]y=-\dfrac{5}{2}x-9[/tex]
Therefore, the correct option is C.

The next model of a sports car will cost 12.2% less than the current model. The current model costs $34,000 . How much will the price decrease in dollars? What will be the price of the next model?
Answer:
Price decrease in dollars = $4,148Price of next model = $29,852Step-by-step explanation:
The next car will be 12.2% cheaper. This amount in dollars is:
= Percentage decrease * Current model price
= 12.2% * 34,000
= $4,148
The price of the next model will therefore be:
= 34,000 - 4,148
= $29,852
Find the equation of the line given the two points below
A(−3,−2) B(6,−8)
Answer:
y = -2/3x - 4
Step-by-step explanation:
Formula: y = mx + b
m (slope)
b (y-intercept)
Slope Formula: y2 - y1 ÷ x2 - x1
Substitute: -8-(-2) = -8+2 = -6
6-(-3) = 6+3 = 9
-6/9 (funny, I know)
Simplify --> -2/3
slope = -2/3
Substitute for the y-intercept --> to do this, we plug in a coordinate pair
-8 = -2/3(6) + b
-8 = -4 + b => add 4 to both sides
b = -4, and thus, our y-intercept is -4
Plug our values into the formula: y = mx + b
y = -2/3x + (-4)
simplify to get our final equation
y = -2/3x - 4
✓ = 2x²-4

Mike needs his bathroom painted. The flat rate for the painting is $25 plus $5 for each hour that they spend painting. If the total cost of the paint job was $75, how many hours did it take for the painting to be completed?
Answer:
10 hours
Step-by-step explanation:
t = 5h + 25
75 = 5h + 25
5h = 50
h = 10
Solve the system and determine whether it is consistent or inconsistent and dependent or independent.
y = -5x – 2
5x + y = 0
1) Find the values of 'a' and 'b' for the given parallelogram *
b+6
a
2a
1229
10
a= 29 and b = 4
O a= 61 and b = 16
O a= 4 and b = 58
none of these
Please please
Answer:
first option
Step-by-step explanation:
In a parallelogram consecutive angle are supplementary, sum to 180, so
2a + 122 = 180 ( subtract 122 from both sides )
2a = 58 ( divide both sides by 2 )
a = 29
---------------
In a parallelogram the opposite sides are congruent, then
b + 6 = 10 ( subtract 6 from both sides )
b = 4
find the direction angel of this vector <-5, 9>
Answer:
θ = -60.94°
Step-by-step explanation:
The given vector is:
v = -5i+9j
We need to find the angle of this vector.
The angle of this vector form is given by :
[tex]\tan\theta=\dfrac{y}{x}\\\\\tan\theta=\dfrac{9}{-5}\\\\\tan\theta=-1.8\\\\\theta=\tan^{-1}(-1.8)\\\\=-60.94^{\circ}[/tex]
So, the angle of this vector is -60.94°.

The volume of a rectangular prism is 360 cm^3. If the length of the prism is 12 cm and the width is 5 cm, what is the surface area of the prism?
Answer:
C) 324 cm^3
Step-by-step explanation:
So you know the volume and 2 side lengths. 360 divided by 12 divided by 5 to find the third side. The third side is 360 / 60 (answer of 12x5), which is 6. Surface area of prism is 324 (c)

15 cm
Find the size of angle x.
Give your answer correct to 1 decimal place.
Answer:
x ≈ 31.0°
Step-by-step explanation:
From the right triangle given in the picture,
By applying tangent rule,
tan(x) = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]
tan(x) = [tex]\frac{9}{15}[/tex]
x = [tex]\text{tan}^{-1}(\frac{9}{15} )[/tex]
x = [tex]\text{tan}^{-1}(0.6)[/tex]
x = 30.96
x ≈ 31.0°
Therefore, measure of angle x is 30.0°
