Answer:

5

Step-by-step explanation:

The equation looks like 4x=20
Divide each side by 4 to get x=5
Thus x+5

Answer:

a=10

Step-by-step explanation:

Using Pythagoras theorem

[tex] {(a + 2)}^{2} + {( a- 5)}^{2} = {(a + 3)}^{2} [/tex]

[tex] {a}^{2} + 4a + 4 + {a}^{2} - 10a + 25 = {a}^{2} + 6a + 9[/tex]

simplify:

[tex] {a}^{2} - 12a + 20 = 0[/tex]

(a-2)(a-10)=0

hence a= 2 or a=10 however we must reject 2 as the lengths of the triangle cannot be negative eg. the side for a-5 will be equivalent to -3 cm which is not possible for lengths to become negative

Answer:

12 < x < 13

Step-by-step explanation:

Pythagorean Theorem: a^2 + b^2 = c^2

a is 6, b is 11, c is x.

We have to first replace the items in the Theorem, do the exponents, then add.

1) 6^2 + 11^2 = x^2

2) 36 + 121 = x^2

3) 157 = x^2

To finally solve it we must square root everything

4) sqrt(157) = sqrt(x^2)

5) x = 12.52

So x has to be between 12 and 13

The reflection mapping of the equation p(-2, 4) is [tex]\mathbf{R_{y =1}(P)=(-2,-2)}[/tex]

To solve this question, we must understand what is reflection mapping is all about.

In mathematical concepts, a reflection is indeed a mapping via a Euclidean plane to itself. The isometry of this usually has a hyperplane with designated fixed points that are commonly referred to as axis.

From the given information, we have:

The given points P = (-2, 4)

Required to find:

[tex]\mathbf{R_{y =1}(P)}[/tex]

Hence, the image of P under the axis(point of reflection line) is y = 1

Thus,

[tex]\mathbf{(x,y) = (x,2k-y)}[/tex]

[tex]\mathbf{(x,y) = (-2,2(1)-4)}[/tex]

[tex]\mathbf{(-2,4) = (-2,-2)}[/tex]

Therefore, we can conclude that the [tex]\mathbf{R_{y =1}(P)=(-2,-2)}[/tex]

Answer:

(4xc)-6=2 then c=2

Step-by-step explanation:

because we knew that we had to do 6+2=8 so then 8 divided by 4 = 2 so the answer would be 2!

Answer:

(4c) - 6 = 2

4c - 6 = 2

c = 2

Both equations will work.

Step-by-step explanation:

"The product of 4 and a number" is the same as 4 times that number.

Since the missing number is to be said as c, the correct term for this is 4c

6 less than (4c) is the same as (4c) - 6

We have the left-hand-side of the equation as (4c) - 6

The right-hand side is 2

Now, we have to solve for c.

Answer:

Read below

Step-by-step explanation:

Slope-intercept form: y = mx + b

where:

1. Rewrite 3x - 4y = -12 into slope-intercept form:

3x - 4y = -12 [subtract 3x from both sides]

3x - 3x - 4y = -12 - 3x

-4y = -3x - 12 [divide both sides by -4]

-4y ÷ -4 = -3x - 12 ÷ -4

[tex]\implies y =\dfrac{3}{4}x + 3[/tex]

Note: with the slope-intercept form, we can quickly see that the y-intercept is (0, 3)

2. Randomly choose x-values that can help you graph the equation:

When x = -8:

[tex]y =\dfrac{3}{4}x + 3\\\\y =\dfrac{3}{4}(-8) + 3\\\\y =-\dfrac{24}{4} + 3\\\\y =-6 + 3\\\\\implies y=-3[/tex]

coordinate: (-8, -3)

When x = -4:

[tex]y =\dfrac{3}{4}x + 3\\\\y =\dfrac{3}{4}(-4) + 3\\\\y =-\dfrac{12}{4} + 3\\\\y =-3 + 3\\\\\implies y=0[/tex]

coordinate: (-4, 0)

When x = 8:

[tex]y =\dfrac{3}{4}x + 3\\\\y =\dfrac{3}{4}(8) + 3\\\\y =\dfrac{24}{4} + 3\\\\y =6 + 3\\\\\implies y=9[/tex]

coordinate: (8, 9)

Graph these coordinates and draw a linear (straight) line through them.

Answer:

Step-by-step explanation:

You have to assume that the triangles are congruent or at least similar. If they are not, the question isn't possible.

If that is so, then <M and <X are equal.

You can find < M by stating that 20 degrees.

That's because <L + <M + <N = 180 degrees. All triangles have 180 degrees.

<L = 70                  Given

<N= 90                  So marked.

70 + <M + 90 = 180

<M = 20 degrees.

<X = <M

<X = 20

Answer:

As x increases, y increases, then y decreases, then y increases again.

Step-by-step explanation:

The relationship between x and y in the graph is as x increases, y increases, then y decreases, then y increases again.

Option C is the correct answer.

The coordinates in a graph indicate the location of a point with respect to the x-axis and y-axis.

The coordinates in a graph show the relationship between the information plotted on the given x-axis and y-axis.

We have,

The graph has the following coordinates.

(0, 0), (3, 3), (4, 0), (5, -4), and (9, 0)

Now,

We see that,

From (0, 0) to (3, 3),

y increases as x increases.

And,

From (3, 3) to (4, 0).

y decreases as x increases.

And,

From (4, 0) to (5, -4).

y decreases as x increases.

And,

From (5, -4) to (9, 0).

y increases as x increases.

Thus,

The relationship between x and y in the graph is as x increases, y increases, then y decreases, then y increases again.
