X-1/3 = y-2/4
4(x-1) = 3(y-2)
4x-4 = 3y-6
4x-3y = -2 --->1
4x +3y =8 ---->2
2-1 ; 6y = 10
y = 10/6 or 5/3
And 4x + 3(10/6) = 8
4x =3
X = 3/4

Type a digit that makes this statement true.

The possible digits that will make 14, 213, 1__2 to be divisible by 4 are;

1, 3, 5, 7 and 9

<h3>Divisibility of Numbers</h3>

We are given the digit as 14, 213, 1__2.

Now, we see that the first of the last two digits is blank and for the give digit 14, 213, 1__2 to be divisible by 4 then the last two digits must be divisible by 4.

Now, since the last 2 digits must be divisible by 4, then it means any singe digit odd number we put in the blank space will yield a combined digit that is divisible by 4. Let us check them;

For 1; 14, 213, 112 ÷ 4 = 3, 553, 278

For 3; 14, 213, 132 ÷ 4 = 3, 553, 283

For 5; 14, 213, 152 ÷ 4 = 3, 553, 288

For 7; 14, 213, 172 ÷ 4 = 3, 553, 293

For 9; 14, 213, 192 ÷ 4 = 3, 553, 298

Y=-x^2-10x+24 What is the y value of the vertex?

emmasim [6.3K]

Answer:

Step-by-step explanation:

1.) Get the equation in the form y = ax^2 + bx + c.

2.) Calculate -b / 2a. This is the x-coordinate of the vertex.

3.) To find the y-coordinate of the vertex, simply plug the value of -b / 2a into the equation for x and solve for y. This is the y-coordinate of the vertex.

1.) y = -x^2 - 10x + 24

2.) -(-10) / 2(-1) = -5

3.) y = -(-5)^2 - 10(-5) + 24

y = -25 + 50 + 24

y = 49

Answer:

$\frac{4x^3-3x^2+5x+6}{x+6}=4x^2-27x+167-\frac{996}{x+6}$

Step-by-step explanation:

The division problem given to us is $(4x^3-3x^2+5x+6)\div (x+6)$ .

To perform the synthetic division, we write out the coefficient of the polynomial. We set the linear factor to zero and solve for x, this becomes our divisor. That is $x+6=0\implies x=-6$ .

We carry out the synthetic division as shown in the attachment.

The result of the synthetic division is 4 -27 167 -996

The first three terms are the coefficients of the quotient and the last term is the remainder.

Therefore the quotient is $q(x)=4x^2-27x+167$ and the remainder is $r(x)=-996$ .

The dividend, the quotient and the divisor are written as

$\frac{4x^3-3x^2+5x+6}{x+6}=4x^2-27x+167-\frac{996}{x+6}$

The correct answer is A

Please someone solve this problem <br>I really need answers

Answer:

x = 50°

y = 50°

z = 80°

Step-by-step explanation:

working out x:

angles on a straight line add up to 180°

x + 130° = 180°

subtract 130 on both sides

x = 180° - 130°

x = 50°

working out y:

two vertical lines means that both sides are equal, so both angles are also equal (it's an isosceles triangle). This means that y is the same angle as x = 50°

y = 50°

working out z:

the sum of a triangle add up to 180°

add up the angles of x and y and equate to 180°

50 + 50 + z = 180

100 + z = 180

subtract 100 on both sides

z = 180 - 100

z = 80°
