Answer 1

Answer:

−1.01

Step-by-step explanation:

Simplify the expression!

Answer 2

Answer: -1.01

Step-by-step explanation:

a double negative equals a positive. -(-1.9) = 1.9

-0.85 + 1.9 = 1.05

when you have a positive number and add a negative number you just subtract the negative number from the positive.

1.05 + - 2.06 = 1.05 - 2.06

1.05 - 2.06 = -1.01

the answer is -1.01

hope this wasn’t confusing!

Answers

Answer:

? = 9

Step-by-step explanation:

you know 99 + 33 = 132 so you can substitute that: 132 = 11 (? + 3). im going to change ? into x for now: 132 = 11 (x + 3). then distribute the 11 so 132 = 11x + 33. then subtract 33 from both sides (99 = 11x) and divide both side by 11 (x = 9) and you get 9!

Answers

y=-2x because the formula for slope intercept form is y=mx+b and m is gonna be the slope, -2, and then b is going to be the y intercept, which is 0 in this particular situation. so your answer is y=-2x because your y intercept is 0

Part 1: Given triangle ABC and AC = BC, find a and the side lengths of the triangle.
a=
Side BC=
Side AC=
Part 2: Based off your knowledge of side lengths and triangles, what can you for sure classify the above triangle as
Triangle ABC:

Answers

Answer:

Part 1)

a=3; BC=10; AC=10

Part 2)

Isosceles Triangle

Step-by-step explanation:

Part 1)

We know that AC=BC.

Therefore, their lengths are equivalent.

So, we can write the following equation:

[tex]6a-8=4a-2[/tex]

Let’s solve for a. Subtract 4a from both sides:

[tex]2a-8=-2[/tex]

Add 8 to both sides:

[tex]2a=6[/tex]

Divide both sides by 2. Therefore, the value of a is:

[tex]a=3[/tex]

Now, we can substitute the value back to find AC and BC.

For AC, we have:

[tex]AC=6a-8\\[/tex]

Substitute 3 for a:

[tex]AC=6(3)-8=18-8=10[/tex]

So, the value of AC is 10.

For BC, we have:

[tex]BC=4a-2[/tex]

Substitute 3 for a:

[tex]BC=4(3)-2=12-2=10[/tex]

Therefore, both AC and BC measure 10 units, which was expected.

Part 2)

Remember that:

A triangle is scalene if all three of its sides are different. A triangle is isosceles if two of its sides are equal. And a triangle is equilateral when all of its sides are equal.

We know that AC is equal to BC. So, two sides are equal.

We don’t know anything about AB. AB could or could not be equal.

Therefore, the best answer is that Triangle ABC is an isosceles triangle.

An x-intercept is a point where a parabola crosses the x-axis and is also known as a zero, root, or solution. Some quadratic functions cross the x-axis twice while others only cross the x-axis once, but this tutorial focuses on quadratic functions that never crosses the x-axis.

The best way to find out whether or not the parabola created by a quadratic formula crosses the x-axis is by graphing the quadratic function, but this is not always possible, so one might have to apply the quadratic formula to solve for x and find a real number where the resulting graph would cross that axis.

The quadratic function is a master class in applying the order of operations, and although the multistep process may seem tedious, it is the most consistent method of finding the x-intercepts. The easiest way to interpret quadratic functions is to break it down and simplify it into its parent function. This way, one can easily determine the values needed for the quadratic formula method of calculating x-intercepts. Remember that the quadratic formula states:


x = [-b +- √(b2 - 4ac)] / 2a
This can be read as x equals negative b plus or minus the square root of b squared minus four times ac over two a. ​The quadratic parent function, on the other hand, reads:


y = ax2 + bx + c
This formula can then be used in an example equation where we want to discover the x-intercept. Take, for instance, the quadratic function y = 2x2 + 40x + 202, and try to apply the quadratic parent function to solve for the x-intercepts. In order to properly solve this equation and simplify it down using the quadratic formula, you must first determine the values of a, b, and c in the formula you’re observing. Comparing it to the quadratic parent function, we can see that a is equal to 2, b is equal to 40, and c is equal to 202.

Next, we’ll need to plug this into the quadratic formula in order to simplify the equation and solve for x. These numbers in the quadratic formula would look something like this:


x = [-40 +- √(402 - 4(2)(202))] / 2(40) or x = (-40 +- √-16) / 80
In order to simplify this, we’ll need to realize a little something about mathematics and algebra first. In order to simplify the above equation, one would have to be able to solve for the square root of -16, which is an imaginary number that does not exist within the world of Algebra. Since the square root of -16 is not a real number and all x-intercepts are by definition real numbers, we can determine that this particular function does not have a real x-intercept.

To check this, plug it into a graphing calculator and witness how the parabola curves upwards and intersects with the y-axis, but does not intercept with the x-axis as it exists above the axis entirely.

The answer to the question “what are the x-intercepts of y = 2x2 + 40x + 202?” can either be phrased as “no real solutions” or “no x-intercepts,” because in the case of Algebra, both are true statements.

Find the value of W please help due tomorrow

Answers

Answer:

59 degrees

Step-by-step explanation:

All the angles of a triangle (when combined) result in 180 degrees. This means that:

Angle 1 + angle 2 + angle 3 = 180 degrees.

We can see here that the shape here is a right triangle (noted by the square in the corner). This means that the angle set with the square is equal to 90. With this, we already have two of our angles! All we need is to set the equation using w, the angle you'll want to find:

31 + 90 + w = 180

w = 59

And there you are! Make sure to practice a few more problems like these to really get the hang of it. Good luck!

D)

Answers

Correct Question:

If OQ and RT are parallel lines and QPS= 77°, what is TSU?

Answer:

77°

Step-by-step explanation:

Since OQ and RT are parallel to each other, and, <TSU and QPS are corresponding angles lying on the same side of the transversal as well as being positioned in the same corner, therefore:

<TSU is congruent to <QPS.

Thus:

m<TSU = m<QPS

m<TSU = 77° (substitution).

Based on the graph of the function y=g(x) shown below, answer the following questions.a) Evaluate each of the following.Illustrate with a point graph.
g(-2)= g(0)=
g(3)= g(7)=
(b) What values of x solve the equation g(x)=0? These are called the zeros of the function

(c)How many values of x solve the equation g(x)=2? How many can you illustrate your answer on the graph?

Answers

a. g(-2)=-3. g(0)=-3
g(3)=4. g(7)=0
b. -3,1,5,7
c. 4 values can solve it

The value of a function is its point on the graph that corresponds to the value of the input variable.

[tex]g(-2) = g(0) = -3[/tex]       [tex]g(3) = 4[/tex]       [tex]g(7) = 0[/tex].The values of x when g(x) = 0 are -3, 1, 5 and 74 values of x solve g(x) = 2

Given that:

[tex]y = g(x)[/tex]

(a) g(-2), g(0), g(3) and g(7)

From the graph, we have:

[tex]g(-2) = -3[/tex]

[tex]g(0) = -3[/tex]

[tex]g(3) = 4[/tex]

[tex]g(7) = 0[/tex]

So, we have:

[tex]g(-2) = g(0) = -3[/tex]

[tex]g(3) = 4[/tex]

[tex]g(7) = 0[/tex]

(b) The values of x when g(x) = 0

These are the points where the graph crosses the x-axis.

The graph crosses the x-axis at: x = -3, 1, 5 and 7

Hence, the values of x are: -3, 1, 5 and 7

(c) The count of values of x for g(x) = 2

This is the number of times the graph passes g(x) = 2

The graph passes g(x) = 2, 4 times.

Hence, 4 values of x solve g(x) = 2
