Simplify 5x ax 5 x a

Answer:

B

Step-by-step explanation:

Quadratic inequalities are inequalities involving quadratics.

A is not an inequality.

B is an inequality and we can rewrite B as:

[tex]x^2+x<0[/tex]

So, B is a quadratic inequality, and is the answer.

C is not a quadratic. The x terms are not squared.

Likewise, D is not a quadratic either since no x terms are being squared.

Given:

The graph of a quadratic function [tex]y=x^2-4x+3[/tex].

To find:

(a) The coordinates of the turning point.

(b) The roots of the equation [tex]y=x^2-4x+3[/tex]

Solution:

(a)

From the given graph it is clear that first the graph is decreasing after that it is increasing. So, the minimum point is the turning point.

The turning is at (2,-1) because the distance between the turning point from the y-axis is 2 and from the x-axis is 1 in the downward direction.

Therefore, the coordinates of the turning point are (2,-1).

(b)

The x-intercepts are the roots of an equation because roots are the x-coordinates of the points where the graph intersect the x-axis.

From the given graph it is clear the graph intersect the x-axis at x=1 and x=3.

Therefore, the roots of the given equation are 1 and 3.

Answer:

(4,7)

Step-by-step explanation:

Answer:

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

[tex]y - x = 5[/tex]

[tex]x = y - 5[/tex]

Step-by-step explanation:

No options were given but the question can still be solved

Given

From the first statement, we have:

[tex]Maria = x[/tex]

From the second, we have:

[tex]Anika = 5\ more[/tex]

Required

Determine the relationship between the amount of rice they bought

5 more means 5 + Maria.

So, [tex]Anika = 5\ more[/tex] becomes

[tex]Anika = 5 + Maria[/tex]

Substitute x for Maria

[tex]Anika = 5 + x[/tex]

For proper expression, let Anika be y

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

Subtract x from both sides

[tex]y - x = 5[/tex]

Make x the subject

[tex]x = y - 5[/tex]

Answer:

The statement that is not true is;

c) m∠ABO = m∠ODC

Step-by-step explanation:

With the assumption that the lengths AO, and OD are equal, we have that in ΔABO and ΔOCD, the following sides are corresponding sides;

Segment AO on ΔABO is a corresponding side to segment OD on ΔOCD

Vertices B and C on ΔABO and ΔOCD are corresponding vertices

Therefore;

Segments AB and OB on ΔABO are corresponding sides to segments OC and OD on ΔOCD respectively

Therefore, ∠ABO on ΔABO is the corresponding angle to ∠OCD on ΔOCD

Given that ΔABO ≅ ΔOCD, we have that ∠ABO ≅ ∠OCD

Therefore;

m∠ABO = m∠OCD by definition of congruency

Answer:

Step-by-step explanation:

Answer:

55

Step-by-step explanation:

AB // DC

∠B + ∠C = 2x + 15 + x = 180

3x = 165

x = 55

Answer: B. 55

Step-by-step explanation:

You need to know that within one parallelogram, the same-side interior angles are supplementary angles, meaning that they add up to 180°.

---------------------------------------------------------------------------------------

Given

(2x+15)+x=180

Expand parenthesis

2x+15+x=180

Combine like terms

3x+15=180

Subtract 15 on both sides

3x+15-15=180-15

3x=165

Divide 3 on both sides

3x/3=165/3

x=55

Please let me know if you have any questions

Answer:

Yes, they will be.

Step-by-step explanation:

Congruent means when they are the same shape and same size.

If triangle ABC is dilated to form triangle DEF, that means that they will have the same shape and the same size.

So yes Triangles ABC and DEF will be congruent to one another because they will be the same shape, and they will have the same size as well.

Answer:

do your work and ask a teacher or parent for help to solve it and stop asking random strangers for the answer and learn how to do it. <3

Step-by-step explanation:

Answer: x= 18

Step-by-step explanation: these are corresponding angles which means they are equal.

(4x-7) = (7x-61)

-7 = 3x -61

54 = 3x

18 = x
