4 x² - x + 1

Answer:

If both numbers have to stay equivalent, then y equals 30 if x = 12. My reasoning is 12/4 = 3. 3 times 10 = 30.

Answer:

[tex]y = \frac{2}{3} x + 12[/tex]

Step-by-step explanation:

[tex]y = - \frac{3}{2} x - 1[/tex]

The gradient of a line is the coefficient of x when the equation of the line is written in the form of y=mx+c.

Thus, gradient of given line=[tex] - \frac{3}{2} [/tex].

The product of the gradients of perpendicular lines is -1.

(Gradient of line)(-3/2)= -1

Gradient of line

[tex]- 1 \div ( - \frac{3}{2} ) \\ = - 1( - \frac{2}{3} ) \\ = \frac{2}{3}[/tex]

Substitute m=[tex]\frac{2}{3} [/tex] into y=mx+c:

[tex]y = \frac{2}{3} x + c[/tex]

To find the value of c, substitute a pair of coordinates.

When x= -6, y= 8,

[tex]8 = \frac{2}{3} ( - 6) + c \\ \\ 8 = - 4 + c \\ c = 8 + 4 \\ c = 12[/tex]

Thus, the equation of the line is [tex]y = \frac{2}{3} x + 12[/tex].

Answer:

[tex]k=3[/tex]

Step-by-step explanation:

Given the following question:

[tex]\frac{9-2k}{3} =k-2[/tex]

To find the answer we need to isolate k, in order to do that we need to use inverse of operations to cancel out integers on each side of the expression.

[tex]\frac{9-2k}{3} =k-2[/tex]
[tex]3\times0=0[/tex]
[tex]2\times3=6[/tex]
[tex]9-2k=k\times3-6[/tex]
[tex]9-9=0[/tex]
[tex]-6-9=15[/tex]
[tex]k\times3=3k[/tex]
[tex]-2k=3k-15[/tex]
[tex]-2k-2k=0[/tex]
[tex]3k+-3k=-5k[/tex]
[tex]-5k=-15[/tex]
[tex]-5k\div-5=k[/tex]
[tex]-15\div-5=3[/tex]
[tex]k=3[/tex]

Your answer is "k =3."

Answer:

1.D(0, 4) → D'(0, –4)

2.E(–2, 0) → E'(–2, 0)

3.The perpendicular distance from G' to the x-axis will equal 2 units.

4.The perpendicular distance from D' to the x-axis will equal 8 units.

5.The orientation will be preserved.

Step-by-step explanation:

D(0, 4) becomes D'(0, –4) and E(–2, 0) becomes E'(–2, 0).

We know that the rule for reflecting over the X axis is to negate the value of the y-coordinate of each point, but leave the x-value the same.

The coordinate of  D(0, 4) becomes D'(0, –4) and coordinate of E(–2, 0) becomes E'(–2, 0).

3.The perpendicular distance from G' to the x-axis is 2 units.

4.The perpendicular distance from D' to the x-axis is 8 units.

Hence D(0, 4) becomes D'(0, –4) and E(–2, 0) becomes E'(–2, 0).

Answer:

[tex]y\leq \frac{1}{2} x+3[/tex]

Step-by-step explanation:

slope intercept form is [tex]y=mx+b[/tex] where [tex]m[/tex] is the gradient and [tex]b[/tex] is the y-intercept (the number at which it crosses the y axis)

firstly find the equation for this line:

the gradient can be found with the formula [tex]\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]

so the gradient is [tex]\frac{4-3}{2-0}=\frac{1}{2} =0.5[/tex]

the y intercept is where it crosses the y axis so it is simply 3

our equation for the line is now [tex]y=\frac{1}{2} x+3[/tex] but the question is asking for an equality where the shaded area is BELOW the line.

so the inequality is [tex]y\leq \frac{1}{2} x+3[/tex]

Answer:

y ≤ [tex]\frac{1}{2}[/tex] x + 3

Step-by-step explanation:

the equation of the line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (- 6, 0) and (x₂, y₂ ) = (0, 3) ← 2 points on the line

m = [tex]\frac{3-0}{0-(-6)}[/tex] = [tex]\frac{3}{0+6}[/tex] = [tex]\frac{3}{6}[/tex] = [tex]\frac{1}{2}[/tex]

the line crosses the y- axis at (0, 3 ) ⇒ c = 3

y = [tex]\frac{1}{2}[/tex] x + 3 ← is the equation of the line

the solution lies below the line and on the line.

as line is solid use ≤

y ≤ [tex]\frac{1}{2}[/tex] x + 3

C: 800 x 20

Step-by-step explanation:

Basically, when you round 778 you see that the 7 and 8 are above 5, which means you round upwards. Therefore it would be best to round up to 800.

Then the 3 in 23 is below 5, meaning you round downwards. 20 Is the closest and best option.

So, C: 800 x 20 is best to do!

Answer:

34 or B

Step-by-step explanation:

180-112=68

68/2=34

Since the 2 angles equal 180, and we already know one is 112, we can subtract that. and because it is 2 times a number, we need to get half of whatever that number is, which was 68, and we got 34. this would be the value of y, because when plugged in, 112+2(34)=180.

Answer:

-1/3

Step-by-step explanation:

2x + 6y = 5

6y = -2x + 5

y = -1/3x + 5/6

Representing the equation in slope intercept form, the slope of the line represented by the equation is - 1/3

Given the equation :

Slope intercept format :

2x + 6y = 5

6y = - 2x + 5

Divide both sides by 6 to isolate y

y = - 1/3x + 5/6

Hence, the value of slope, b in the equation is - 1/3
