solve for x
A)8
B)9

D)-8
Answer:
C) -9
Step-by-step explanation:
x + 19 must be half x + 29 because triangles RBC and RST are similar by SAS and RB is half of RS and RC is half of RT.
2(x + 19) = x + 29
2x + 38 = x + 29

If ABC is reflected across the y-axis, what are the coordinates of C?
A. (6,-3)
B. (3,-6)
C. (-6,-3)
D. (-6,3)
Answer:
Step-by-step explanation:
The correct answer would be C (-6,3). The y axis is the bold line going up and down on the middle of the page. If you were able to pick up triangle and flip it over the y axis. Point C would land at (-6,3).
Also, you can see that point C is six spaces to the right of the y axis. That means when we flipped it over the axis, it will now be six paces to the right of the y axis. Since the point did not go up or down when you flipped it. It is still 3 spaces above the x axis.
Answer:
D (-6, 3)
Step-by-step explanation:
the point C is originally (6, 3).
that means the x coordinate is 6, the y coordinate is 3.
now, if we reflect (= mirror) that point across the y axis, that means we mirror it to the other side of the y axis.
the y axis is the vertical coordinate axis in the middle of the graph.
so, what is going to happen to the point ?
will the y coordinate change ? no. the point will move over to the other side of the y line in the same "height" as before. nothing will move it higher or lower.
so, it will keep the same y coordinate : 3.
will the x coordinate change ? oh, yes. because the point will move from the right of the y axis to the left of the y axis. and it will be the same distance to the left as it was originally to the right.
so, +6 turns into -6 (as the y axis represents x=0).

Answer:
a) x = 1.5 or x = -0.3
b) x = 5 or x = -8
Explanation:
Quadratic formula:
[tex]\sf x = \dfrac{ -b \pm \sqrt{b^2 - 4ac}}{2a} \quad when \:\: ax^2 + bx + c = 0[/tex]
Here given equation: 5x² - 6x - 2 = 0
Identify variable constants: a = 5, b = -6, c = -2
Putting these values into equation:
[tex]\sf x = \dfrac{ -(-6) \pm \sqrt{(-6)^2 - 4(5)(-2)}}{2(5)}[/tex]
[tex]\sf x = \dfrac{ 6 \pm \sqrt{36 + 40}}{10}[/tex]
[tex]\sf x = \dfrac{ 6 \pm \sqrt{76}}{10}[/tex]
[tex]\sf x = \dfrac{ 3\pm \sqrt{76}}{5}[/tex]
[tex]\sf x = \dfrac{ 3+ \sqrt{76}}{5} \quad or \quad \dfrac{ 3- \sqrt{76}}{5}[/tex]
In one decimal point:
[tex]\sf x = 1.5 \quad or \quad -0.3[/tex]
b) Here use "middle term split" method
⇒ x² + 3x = 40
relocate
⇒ x² + 3x - 40 = 0
The factors of 40 are 8 and 5
⇒ x² + 8x - 5x - 40 = 0
factor common terms
⇒ x(x + 8) - 5(x + 8) = 0
collect into groups
⇒ (x - 5)(x + 8) = 0
set to zero
⇒ x - 5 = 0 or x + 8 = 0
relocate
⇒ x = 5 or x = -8
Step-by-step explanation:
a) The quadratic formula can help find answers to a quadratic equation when it is equal to 0. The formula is [tex]x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}[/tex] for a quadratic equation of the form [tex]ax^2+bx+c=0[/tex].
In this question, a is 5, b is -6, and c is -2. Let's put them in the equation and solve.
[tex]x=\frac{6\pm\sqrt{(-6)^2-4(5)(-2)}}{2(5)}\\x=\frac{6\pm\sqrt{36+40}}{10}\\x=\frac{6\pm\sqrt{76}}{10}\\x=\frac{6\pm2\sqrt{19}}{10}\\x=\frac{3\pm\sqrt{19}}{5}[/tex]
This means that the value of x is both [tex]\frac{3+\sqrt{19}}5[/tex] and [tex]\frac{3-\sqrt{19}}5[/tex], since both values make x equal to 0. Putting both into the calculator, we get that [tex]x=1.5[/tex] or [tex]x=-0.3[/tex].
b) We can easily solve this equation using factoring, which turns a quadratic into two factors, and finds the solutions by setting both to 0. This will only work if the quadratic is equal to 0.
[tex]x^2+3x-40=0[/tex]
Now, we have to find two numbers that add to 3 and multiply to -40. The numbers 8 and -5 work, as 8-5=3 and 8*-5 is -40.
we can now make our factors x+8 and x-5
[tex](x+8)(x-5)=0[/tex]
If two numbers, say A and B, are being multiplied and equal 0, then either A is 0, or b is 0, or both. Similarly, if x+8 and x-5 are being multiplied and equal 0, either x+8 = 0, or x-5=0.
[tex]x+8=0\\x=-8[/tex] [tex]x-5=0\\x=5[/tex]
This makes our solutions x=-8 and x=5.
If you are not familiar with factoring or the process I have went through above, I highly recommend learning about it.

Answer:
This would be true for a rectangle and a square.

Oops, looks like I’m stuck. Can someone please explain to me in detail why 1 plus 1 isn’t 3? (Giving brainliest to the lengthiest and best answer)
By assuming that 1 + 1 = 3, we will reach an absurd.
How to prove that 1 + 1 isn't 3?
To do this, we need to reach an absurd.
Let's assume that we are working with integer numbers, and let's assume that 1 + 1 is equal to 3.
Then we can write:
1 + 1 = 3
Now, if we subtract 1 in both sides, we get:
(1 + 1) - 1 = 3 - 1
1 = 2
Now we can subtract 1 again so we get:
1 - 1 = 2 - 1
0 = 1
This is an absurd, then the statement:
1 + 1 = 3
is false.
So we conclude that:
1 + 1 isn't 3.

Yes, the given line can be used to make reasonable predictions of the number of cheese pizzas that will be sold, since the scatter points clearly show a trend.
As time goes on, the number of pizzas sold is getting bigger, and the trend is what created the line.
The data was taken over 8 consecutive weeks, so we can assume that it can be used in our prediction.
Since the trend has been pretty consistent over periods of time, we can expect it to continue in the upcoming weeks.

the 4th answer option. W = 153°, P = 71°
Step-by-step explanation:
PQRS ~ TUVW
that means both figures are similar.
and that means that the angles at the corresponding vertexes are the same, and all 4 corresponding sides (and any other pair of corresponding lines like diagonals) have the same scaling factor.
we see due to the proportions of the different parts of the shapes
U corresponds to Q.
T corresponds to P.
W corresponds to S.
V corresponds to R.
therefore, as the angle at S = 153°, so is W.
and as the angle at T = 71°, so is P.

On a coordinate plane, line k l goes through (negative 6, 8) and (6, 0). point m is at (negative 4, negative 2). which point could be on the line that is parallel to line kl and passes through point m?
The equation of the line parallel to the line KL passing through the points (-6, 8) and (6, 0), and going through the point M (-4, -2) is 2x + 3y = -6. The point satisfying this equation is (-6, 2). Thus, the 2nd option is the right choice.
Slope of the line KL = (8 - 0)/(-6 - 6) = 8/(-12) = -2/3.
Using the formula of the slope of the line passing through the points (x₂, y₂) and (x₁, y₁), as m = (y₂ - y₁)/(x₂ - x₁).
The slope of the line parallel to the line KL will be equal to the slope of KL.
Thus, the slope of the required line is m = -2/3.
The required line also passes through point M (-4, -2).
Thus, the equation of the required line will be,
y - (-2) = (-2/3)(x - (-4)) {Using the equation of the line passing through the point (x₁, y₁) and a slope m, as y - y₁ = m(x - x₁)},
or, y + 2 = (-2/3)(x + 4),
or, 3(y + 2) = -2x - 8,
or, 2x + 3y = -6.
From the given points, only the point (-6, 2) satisfies the equation.
Thus, the equation of the line parallel to the line KL passing through the points (-6, 8) and (6, 0), and going through the point M (-4, -2) is 2x + 3y = -6. The point satisfying this equation is (-6, 2). Thus, the 2nd option is the right choice.

In a right triangle, one acute angle is 22 degrees less than 3 times the other acute angle. What is the measure of the larger acute angle
The measure of the acute angles are 62° and 28° .
What is the larger acute angle in a right triangle?The Triangle Angle Sum Theorem states that the sum of all interior angles in a triangle is . Additionally, the Right Triangle Acute Angle Theorem states that the two non-right angles in a right triangle are acute; that is to say, the right angle is always the largest angle in a right triangle.Let x represent the measure of one of the acute angles of the right angle triangle.
Let y represent the measure of the other acute angle of the right angle triangle.
One of the acute angles in a right triangle measures 22 degrees less than 3 times the other acute angle. This means that
x = 3y - 22
The sum of two acute angles in a right triangle is 90 degrees.
We write as
x + y = 90 - - - - - - - (1)
Substituting x = 3y - 22 into equation 1, it becomes
3y - 22 + y = 90
4y = 90 + 22= 112
y = 112/4 = 28
