Use the quadratic formula to solve the equation, which has one solution. y2+2y+1=0

Answer:

x = 38

y = 41

z = 123

Step-by-step explanation:

x + y + z = =202

y = x + 3

z = 3y = 3(x + 3) = 3x + 9

x + y + z = x + x + 3 + 3x + 9 = 5x + 12 = 202

5x + 12 = 202

5x = 190

x = 38

y = x + 3 = 41

z = 3y = 123

Answer: 30x⁴

Step-by-step explanation:

2x⁴ + (-3x²)² + 10(x²)² + (-3x²)²

2x⁴ + (9x⁴) + 10 (x⁴) + (9x⁴)

2x⁴ + 9x⁴ + 10x⁴ + 9x⁴

2x⁴ + 10x⁴ 9x⁴ + 9x⁴

Answer:

[tex]\boxed{\textsf{ The first negative term of the sequence is \textbf{-4} .}}[/tex]

Step-by-step explanation:

A sequence is given to us . And we need to find the first negative term of the sequence. So the given sequence to us is :-

[tex]\sf\implies Sequence = 31 , 26 , 21 , 16 ..... [/tex]

Here first term of the sequence is 31. And the common difference is 26 - 31 = -5 . Hence here (-5) is added to each number to obtain the second number of the sequence .

Here the last term mentioned is 16. And we are subsequently adding (-5) to each term to obtain the next term . Next third term will be obtained after adding 5×(-3) = -15 .

And that term will be , 16 - 15 = 1 .

Hence the last positive term is 1 . The next term term after adding (-5) will be the first negative term.

[tex]\sf \implies 1st \ negative \ term = 1 -5 =\pink{-4} . [/tex]

Answer:

39 degrees

Step-by-step explanation:

Vertical angles are opposite angles made by two intersecting lines, this means they share a vertex. Vertical angles are always congruent. Congruent angles have the same measurements, so the other angle must be 39 degrees.

Answer:

A

Step-by-step explanation:

-4 is the y-intercept, so there will always be an arrow that crosses over that point. And for the slope (2x) you need to go up two places from the y-intercept and then one to the right :)

Answer:

A

Step-by-step explanation:

The 2 in 2x-4 tells us that the line is rising, so that disqualifies answer B and C.

The -4 tells us the line passes the y axis at -4, so that disqualifies C and D.

Leaves A!

Answer:

Step-by-step explanation:

Because the function is a product, the zeros will occur when any term is equal to zero. For

(x-1)(x+3)(2x+1) the value will be zero when x=1,-3, or -1/2 so the points are

(-3,0), (-1/2,0), and (1,0)

The zeroes of the polynomials are, x=1,-3, or -1/2,Because the function is a product, zeros will appear whenever any term equals zero.

Zeros  are the Intersection points of the curve of the considered function on the input axis.

y-intercept Points on the output axis where the curve of the considered function intersects.

On the x-axis, the value of the y-coordinate is 0. On the y-axis, the value of the x-coordinate is 0.

Thus, if the function is y=f(x), then placing y = 0 yields the function's zeros. Putting x = 0 produces the function's y-intercept.

Because the function is a product, the zeros will occur when any term is equal to zero.

(x-1)(x+3)(2x+1) =0

x=1,-3, or -1/2

The zeroes of the polynomials are, x=1,-3, or -1/2

8x6=48 =x

6x6=36

equation= 6x*6-48=x

Answer:

There are 3 possible answers because you didn't state which value was base or height.

Going off the assumption that the base is 15 cm and the height is 8 cm, the area is 60 cm. (same answer if base is 8 cm and height is 15 cm)

A = 1/2(b*h)

A = 1/2(15*8)

A = 1/2(120)

A = 60

Going off the assumption that the base is 17 cm and the height is 8 cm, the area is 68 cm. (same answer if base is 8 cm and height is 17 cm)

A = 1/2(b*h)

A = 1/2(17*8)

A = 1/2(136)

A = 68

Going off the assumption that the base is 15 cm and the height is 17 cm, the area is 127.5 cm. (same answer if base is 17 cm and the height is 15 cm)

A = 1/2(b*h)

A = 1/2(15*17)

A = 1/2(255)

A = 127.5
