Solve x^2+5x=-6 please solve this using quadratics

Answer:

The answer to this is B, because supplementary angles sum up to 180 degrees, which means it is a straight angle.

Answer:

Option B and D

Step-by-step explanation:

Given are four options and we have to select the one which form a straight angle.

The given options are

A. Vertical Angles  ... Vertical angles are formed when two lines intersect and hence cannot combine to form a straight angle.  Incorrect option.

B. Supplementary Angles ... Supplementary angles are a pair of angles which add upto 180 degrees and hence they form a straight angle. Correct option

C. Complementary Angles  ... These pair add up to 90 degrees and cannot combine to form a straight angle.  ..  Incorrect

D. Linear Pair ... A linear pair is a pair of angles formed on a straight line and hence correct option.

Answer:

7/5 time 7/8 is exactly: 2 11/40

Step-by-step explanation:

Hello.

First we need to multiply across.

7 x 7 is 49 so that's our top number.

49

----   5 x 8 is 40 so that would be our bottom number.

?

You would write it  [tex]\fbox{49/40}[/tex].

As a mixed number it would be [tex]\fbox{1 9/40}[/tex] Note that it is not 19 if you read it wrong.

Answer:

206  2/3 ft³

Step-by-step explanation:

The volume of this solid is given by V = (1/3)(base area)(height).

Here, V = (1/3) (62 ft²) (10 ft ) = 206  2/3 ft³

I think the answer is 44

When w is 5 both expressions have the same value 24.

When w is 10 both expressions have the same value 84.

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

Substitute w = 5

12 (w - 3)

= 12 (5 - 3)

= 12 x 2

= 24

And,

12w - 36

= 12 x 5  - 36

= 60 - 36

= 24

Now,

Substitute w = 10

12 (w - 3)

= 12 (10 - 3)

= 12 x 7

= 84

And,

12w - 36

= 12 x 10 - 36

= 120 - 36

= 84

Thus,

When w is 5 both expressions have the same value.

When w is 10 both expressions have the same value.

When [tex]\( w = 10 \),[/tex]both expressions have a value of 84, and the expressions are indeed equivalent.

To determine if the two expressions [tex]\(12(w - 3)\) and \(12w - 36\)[/tex] are equivalent, we can evaluate both expressions for the given values of [tex]\(w\).[/tex]

When [tex]\(w = 5\),[/tex]we substitute [tex]\(5\)[/tex]into both expressions:

For the expression [tex]\(12(w - 3)\):[/tex]

[tex]\[12(5 - 3) = 12(2) = 24\][/tex]

For the expression [tex]\(12w - 36\):[/tex]

[tex]\[12(5) - 36 = 60 - 36 = 24\][/tex]

Both expressions evaluate to [tex]\(24\) when \(w = 5\).[/tex]

Now, let's evaluate both expressions when [tex]\(w = 10\):[/tex]

For the expression [tex]\(12(w - 3)\):[/tex]

[tex]\[12(10 - 3) = 12(7) = 84\][/tex]

For the expression [tex]\(12w - 36\):[/tex]

[tex]\[12(10) - 36 = 120 - 36 = 84\][/tex]

Since the values of both expressions are the same for [tex]\( w = 5 \) and \( w = 10 \),[/tex]we can conclude that the expressions are equivalent.

Answer: [tex]g(x)=\frac{1}{9}x^2[/tex]

Step-by-step explanation:

By definition, he quadratic parent function [tex]f(x)=x^2[/tex] is the simplest form of a quadratic function.

By definition, if the fucntion is multiplied by the factor b and:

 |b|>0  the function is stretched.

If 0<|b|<1 the function is compressed.

Then the new function will have the form:

[tex]g(x)=(\frac{1}{b}x)^2[/tex]

Therefore, keeping the above on mind, if b=3, then the new function is:

[tex]g(x)=(\frac{1}{3}x)^2[/tex]

[tex]g(x)=\frac{1}{9}x^2[/tex]

EXPLANATION

The given line has equation

[tex]3y + 5x = 4[/tex]

Rewrite the equation in the form:

[tex]y = mx + b[/tex]

Add -5x to both sides.

[tex]3y + 5x - 5x = - 5x + 4[/tex]

[tex]3y = - 5x + 4[/tex]

Divide through by 3.

[tex]y = - \frac{5}{3}x + \frac{4}{3} [/tex]

Comparing to the slope intercept formula,

Answer:

5 cm

Step-by-step explanation:

If AB is tangent to the circle k(O), then radius OB is perpendicular to segment AB.

If BC is tangent to the circle k(O), then radius OC is perpendicular to segment AC.

Consider two right triangles ABO and ACO. In these triangles:

By HL theorem, triangles ABO and ACO are congruent. Then

Hence, ∠BAC=∠OAB+∠OAC=30°+30°=60°.

Consider triangle ABC, this triangle is isosceles triangle. In isosceles triangles angles adjacent to the base are congruent, thus

∠CBA=∠BCA=1/2(180°-60°)=60°.

Therefore, triangle ABC is an equilateral triangle, so BC=AB=AC=5 cm.

Answer:

h(-8) = 22

Step-by-step explanation:

Plug  -8 in for t and simplify...

h(-8) = 2(-8 + 5)² + 4

    h(-8) = 2(-3)² + 4

        h(-8) = 2(9) + 4

          h(-8) = 18 + 4

             h(-8) = 22

Answer:

Step-by-step explanation:

Given h(f)=-2(t+5)^2 +4

There is an intermediate step which is

h(f) = -2(f + 5)^2 + 4

h(-8) = -2(-8 + 5)^2 + 4

h(-8) = -2(-3)^2 + 4

h(-8) = -2(9) + 4

h(-8) = -18 + 4

h(-8) = - 14

Answer:

B) 44

Step-by-step explanation:

Let's start with the triangles. Normally, when dealing with triangles, you would use the formula (B*H*1/2), but since there's two identical triangles, we can just do (B*H) and get the area for both:

2.5*5.5=13.75

Then to solve for the square, it is also (B*H):

5.5*5.5=30.25

At this point, to solve for the total area, you just add the areas together:

13.75+30.25=44

Hope this helps!

[tex]\large\boxed{x^2+y^2+4x-2y+1=0}[/tex]

Step-by-step explanation:

The standard form of an equation of a circle:

[tex](x-h)^2+(y-k)^2=r^2[/tex]

(h, k) - center

r - radius

The general form of an equation of a circle:

[tex]x^2+y^2+Dx+Ey+F=0[/tex]

We have the center (-2, 1). Substitute to the equation in the standard form:

[tex](x-(-2))^2+(y-1)^2=r^2\\\\(x+2)^2+(y-1)^2=r^2[/tex]

Put thr coordinates of the point (-4, 1) to the equation and calculate a radius:

[tex](-4+2)^2+(1-1)^2=r^2\\\\r^2=(-2)^2+0^2\\\\r^2=4[/tex]

Therefore we have the equation:

[tex](x+2)^2+(y-1)^2=4[/tex]

Convert to the general form.

Use [tex](a\pm b)^2=a^2\pm 2ab+b^2[/tex]

[tex](x+2)^2+(y-1)^2=4\\\\x^2+2(x)(2)+2^2+y^2-2(y)(1)+1^2=4\\\\x^2+4x+4+y^2-2y+1=4\qquad\text{subtract 4 from both sides}\\\\x^2+y^2+4x-2y+1=0[/tex]

Answer:

C

Step-by-step explanation:

Let's break down the definitions.

diameter = a line across the circle that crosses the center

radius = a line from the center of the circle to any edge

chord = a line with both endpoints on the edge of the circle

arc = the outside part of the circle

Since this line has both endpoints on the edge of the circle and does not cross the center, the line is a chord.

Answer:

80

Step-by-step explanation:

The median is the middle value of the data arranged in ascending order. If there is no exact middle then the median is the average of the 2 values either side of the middle

Arrange the data in ascending order ( smallest to largest )

32, 77, 78, 82, 85, 87

There is no value exactly in the middle, use the average

median = [tex]\frac{78+82}{2}[/tex] = [tex]\frac{160}{2}[/tex] = 80

ANSWER

y=x

y=x³

EXPLANATION

A function, f(x) has an inverse if and only if

[tex]f(a) = f(b) \Rightarrow \: a = b[/tex]

Thus, the function is one to one.

For y=x or

[tex]f(x) = x[/tex]

[tex]f(a) = f(b) \Rightarrow \: a = b[/tex]

Hence this function has an inverse.

For the function y=x² or f(x)=x².

[tex]f(a) = f(b) \Rightarrow \: {a}^{2} = {b}^{2} \Rightarrow \: a = \pm \: b[/tex]

This function has no inverse on the entire real numbers.

For the function y=x³ or f(x)=x³

[tex]f(a) = f(b) \Rightarrow \: {a}^{3} = {b}^{3} \Rightarrow \: a = b[/tex]

This function also has an inverse.

For y=x⁴ or f(x) =x⁴

[tex]f(a) = f(b) \Rightarrow \: {a}^{4} = {b}^{4} \Rightarrow \: a = \pm \: b[/tex]

This function has no inverse over the entire real numbers.

Answer:

The function [tex]x=y[/tex] and [tex]y=x^{3}[/tex] are inverse function.

Step-by-step explanation:

Function inverse definition:

If a provided function f(x) is mapped x to y, then the inverse of the provided function f(x) is mapped y to x.

Or  [tex]f(x)=f(y)\Rightarrow x=y[/tex]

Now, consider the function y = x.

Interchange the variables x and y.

[tex]x=y[/tex]

Now, solve [tex]x=y[/tex] for [tex]y[/tex].

[tex]x=y[/tex]

Therefore, this function has an inverse.

Consider the function [tex]y=x^{2}[/tex].

Interchange the variables x and y.

[tex]x=y^{2}[/tex]

Now, solve [tex]x=y^{2}[/tex] for [tex]y[/tex].

[tex]\pm \sqrt{x} =y[/tex]

Therefore, the function has no inverse.

Consider the function [tex]y=x^{3}[/tex].

Interchange the variables x and y.

[tex]x=y^{3}[/tex]

Now, solve [tex]x=y^{3}[/tex] for [tex]y[/tex].

[tex]\sqrt[3]{x}=y[/tex]

Therefore, the function has inverse.

Consider the function [tex]y=x^{4}[/tex].

Interchange the variables x and y.

[tex]x=y^{4}[/tex]

Now, solve [tex]x=y^{4}[/tex] for [tex]y[/tex].

[tex]\pm \sqrt[4]{x}=y[/tex]

Therefore, the function has no inverse.

Hence, the function [tex]x=y[/tex] and [tex]y=x^{3}[/tex] are inverse function.
