Answer:

y = 2 (x + seven-halves) squared minus one-fourth [y =  [tex](x + \frac{7}{2} )^{2} - \frac{1}{4}[/tex] ]

Step-by-step explanation:

We know that,

vertex form is y = a(x-h)² + k

vertex is (h, k)

Now,

Given that the equation is -

y = (x+3)² + (x+4)²

 = x² + 3² + 2×3×x + x² + 4² + 2×4×x

= x² + 9 + 6x + x² + 16 + 8x

= 2x² + 14x + 25

= [tex]x^{2} + 7x + \frac{25}{2}[/tex]

= [tex]x^{2} + 7x + \frac{25}{2} + \frac{49}{4} - \frac{49}{4}[/tex]

= [tex](x + \frac{7}{2} )^{2} + \frac{25}{2} - \frac{49}{4}[/tex]

= [tex](x + \frac{7}{2} )^{2} - \frac{1}{4}[/tex]

∴ we get

The vertex form is -

y = [tex](x + \frac{7}{2} )^{2} - \frac{1}{4}[/tex]

So,

The correct option is - y = 2 (x + seven-halves) squared minus one-fourth (y =  [tex](x + \frac{7}{2} )^{2} - \frac{1}{4}[/tex] )

Answer:

Step-by-step explanation;

54+8p+4=90

58+8p=90

8p=90-58

8p=32

p=32/8

thus,p=4

8p+4=8×4+4=32+4=36

Answer:

Reflected across thhe Y-Axis (I think thats what your looking for)

Answer:

y=-2x-6

Step-by-step explanation:

Slope intercept form of a line: y=mx+b (m is the slope and b is the y-intercept)

Convert our given line 6x+3y=4 into slope-intercept form to find the slope

Subtract 6x on both sides

3y=-6x+4

Divide 3 on both sides

y=-2x+4/3

The slope of the given line is the coefficient of x, -2

Parallel lines have the same slope, so the equation we're solving for also has a slope of -2

We also know that the y-intercept is -6, so we now have all the info we need to make the equation:

y=-2x-6

Answer:

no solution

Step-by-step explanation:

Answer:

If the slope is different - always one solution

if the slope is the same but the y intercept is different - no solution

if the slope and y intercept are the same - infinite number of solutions

Answer:

Step-by-step explanation:

Width, Length, and Height being combine it by multiplying.

For a regular prism (where all the sides are the same) calculate the area of one of the sides and multiply by the total number of sides. For irregular prisms (with different sides) calculate the area of each side. Add your two answers together (ends × sides) to find the total surface area of the prism.

Model 2

Step-by-step explanation:

1.56 + 0.33 = 1.89

Answer:

Step-by-step explanation:

So let the angles be 2x,3x,5x

∠A + ∠B + ∠C + ∠C = 360  

[Sum of all the angles of a quadrilateral ]

⇒2x+3x+5x+130=360  

⇒10x = 360 -130  

⇒x =  23

The angles are ,

∠A = 2x = 2×23 = 46

∠B = 3x = 3×23 = 69  

∠C = 5x = 5×23=115

Let the angles be 2x,3x and 5x

We know that 2x+3x+5x+130=360

10x+130=360

10x=230

Therefore x=23°

2x=46°

3x=69°

5x=115°

Answer:

-2

Step-by-step explanation:

This looks super complicated, but it can actually be solved with the application of a couple of area equations.

Let's establish one fact before we start this question that may have been the reason why this was so confusing for you. No matter what kind of triangle, the area will always be [tex]\frac{1}{2}[/tex] times the length of the base times height.

Alright, with that established, let's start trying to solve for the area.

In this question, we seem to have a triangle with a circle shape taken out of it. We are told to find the area of the shaded area.

The overall equation would be:

[tex]Area_{triangle}[/tex] - [tex]Area_{circle}[/tex]

This makes sense, right? If we find the area of the triangle and subtract the area of the circle within it, it should give us the total shaded area.

Now, let's begin solving for said shaded area:

[tex]Area_{triangle}[/tex] - [tex]Area_{circle}[/tex]

([tex]\frac{1}{2}[/tex] * base * height) - (π*[tex]r^{2}[/tex])

The given base of the triangle is 40 km, the height 27 km, and the circle's diameter is 12. Therefore:

([tex]\frac{1}{2}[/tex] * 40 * 27) - (π * [tex](\frac{12}{2})^{2}[/tex])

(540) - (π * [tex]6^{2}[/tex])

540 - 36π

Use 3.14 as the value for pi:

540 - 36(3.14)

426.96

Round to the nearest tenth:

427.0

Shaded area = 427 ([tex]km^{2}[/tex])

Answer:

x=32, x=0

Step-by-step explanation:

[tex](x-16)^2=256[/tex]

Take the square root of both sides

[tex]\sqrt{ (x-16)^2}=\±\sqrt{256}\\x-16=\±16[/tex]

x=16+16 or x=16-16

Therefore, x=32 or x=0

I hope this helps!
