Simply this equation 8-4(7b+5)

Answer:

y =1

Step-by-step explanation:

2(1) +3(1)=5

2+3=5

Answer:

y=5/3-2/3

Step-by-step explanation:

1. Move the variable to the right-hand side and change its sign

3y=5-2x

2. Divide both sides of the equation by

y=5/3-2/3

Answer:

8.5>d+10

Step 1: Flip the equation.

d+10<8.5

Step 2: Subtract 10 from both sides.

d+10−10<8.5−10

d<−1.5

Answer:

[tex]y = -2x +7[/tex]

Step-by-step explanation:

Given

[tex](x_1,y_1) = (-3,13)[/tex]

[tex](x_2,y_2) = (6,-5)[/tex]

Required

Determine the equation in slope intercept form

First, we calculate the slope:

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

The equation becomes:

[tex]m = \frac{-5 - 13}{6 - (-3)}[/tex]

[tex]m = \frac{-5 - 13}{6 +3}[/tex]

[tex]m = \frac{-18}{9}[/tex]

[tex]m = -2[/tex]

The equation is then calculated using:

[tex]y -y_1 = m(x - x_1)[/tex]

Substitute values for y1, m and x1

[tex]y - 13 = -2(x -(-3))[/tex]

[tex]y - 13 = -2(x +3)[/tex]

[tex]y - 13 = -2x -6[/tex]

Make y the subject

[tex]y = -2x - 6 + 13[/tex]

[tex]y = -2x +7[/tex]

Answer:

This system of equations has no solutions

Step-by-step explanation:

in the linear equations, if the variable is disappeared, and

Let us solve the question

∵ x = 2y ⇒ (1)

∵ 6y - 3x = 18 ⇒ (2)

→ Substitute x in equation (2) by the value of x in equation (1)

∵ 6y - 3(2y) = 18

∴ 6y - 6y = 18

∴ 0 = 18

→ 0 can not equal 18

∴ Left hand side ≠ Right hand side

→ From the 2nd note above

∴ This system of equations has no solutions

Answer:

-2

Step-by-step explanation:

f(x) = –x– 5

f(x) = -(-3)– 5

f(x) = 3– 5

f(x) = -2

Answer:

Answer is -2 because - * - = + 3-5=-2

Answer:

B

Step-by-step explanation:

Answer:

P(x) = x³-2ix² - 49x + 98i

Step-by-step explanation:

If the roots of the polynomial P(x) are -7, 2i and 7 then the factors of the polynomial in x is expressed are respectively (x+7), x-2i and x-7

Multiplying the factors together to get the required polynomial function:

P(x) = (x+7)(x-7)(x-2i)

P(x) = (x²-7x+7x-49)(x-2i)

P(x) = (x²-49)(x-2i)

P(x) = x²(x)-x²(2i) - 49x -49(-2i)

P(x) = x³-2ix² - 49x + 98i

Hence the polynomial function with degree 3 is P(x) = x³-2ix² - 49x + 98i

Answer:

252 cubic cm

Step-by-step explanation:

V = (l x w x h ) / 3

V = (6 cm x 9 cm x 14cm) / 3

V = 756/3 =  252 cubic cm

Answer:

252 cubic cm

Step-by-step explanation:

[tex]B_{p}[/tex]=(1/3)Bh

B=l*w

B=6*9=54

h=14

[tex]B_{p}[/tex]=1/3(54)(14)=252 cubic cm

Answer:

5 1/2 hours

Step-by-step explanation:

by a factor of 5 means times 4

6*4=24

22/4=5.5 hours

It will take 88 hours to complete the homework.

Given is that all of the middle school mathletes solve math problems at the same pace. Working together, 6 mathletes complete all of the summer homework in 22 hours.

6 mathletes complete all of the summer homework in 22 hours.

If the number of mathletes increases by a factor of 4, the number of mathletes will be (4 x 6) = 24 mathletes.

We can write -

1 mathlete will complete all of the summer homework in (22/6) hours.

24 mathlete will complete all of the summer homework in (22/6 x 24) hours.

(22/6 x 24)

(22 x 4)

88

Therefore, it will take 88 hours to complete the homework.

Answer:

41

Step-by-step explanation:

Answer:

41

Step-by-step explanation:

angle 7 and angle 4 are corresponding angles.

corresponding angles are equal

∠7 = ∠4

∠7 = 41

41 = ∠4

Answer:

O1: b) linear, proportional

O2: a) linear, non-proportional

O3: c) nonlinear

Step-by-step explanation:

Recall that a proportional function can be drawn as a straight line (linear function) through the origin (0,0).

O1 is a proportional function since it is linear and goes through the origin.

O2 has a y-intercept of y = 5; therefore, it is not proportional because it does not go through the origin (0,0), although it is linear.

O3 resembles a quadratic function, which means it's not a linear function (nonlinear).

Answer:

irrational

Step-by-step explanation:

if we make a square root of 8. We all know that the product of rational and irrational is always irrational. Hence the product will be irrational.

Answer:

-4 and -2

Step-by-step explanation:

Sum = - 6

[tex] - 4 + ( - 2) \\ - 4 - 2 = - 6[/tex]

The product = 8

[tex]( - 4) \times ( - 2) = 8[/tex]

Remind that negative multiply negative equal positive.

Answer:

f(-2)

Step-by-step explanation:

Answer:

- 53, - 207, - 7

Step-by-step explanation:

To obtain f(- 2), substitute x = - 2 into f(x), that is

f(- 2) = - 9(- 2)² + 5(- 2) - 7 = - 9(4) - 10 - 7 = - 36 - 10 - 7 = - 53

(b)

Similarly substitute x = 5 into f(x)

f(5) = - 9(5)² + 5(5) - 7 = - 9(25) + 25 - 7 = - 225 + 25 - 7 = - 207

(c)

f(0) = - 9(0)² + 5(0) - 7 = 0 + 0 - 7 = - 7

Answer:

Slope: -2/3

Y-intercept: (0, 9)

Equation: y = -x + 9

3 blocks away: 6 visits

Step-by-step explanation:

Calculate slope from point (1, 8) to point (3, 7) on the line.

The y-intercept is where the line meets the y-axis.

The equation took a bit of guessing, but the -x is the y = x line, but reversed. 9 is the y-intercept.

Check the point on the line where x = 3.

Hope this helps!
