Answer:

Step-by-step explanation:

in y = mx + b form, the slope is in the m position

y = -6x + 5......slope here is -6

y = -4x + 5....slope here is -4

so the slope changed from -6 to -4

** the slope with the highest absolute value is steepest.....lol...is steepest even a word

so the slope of the new graph would become less steep <==

Please solve, -7x+8=-4(x+1)

omeli [17]

Answer: $x=4$

Simplify both sides of the equation.

$-7x+8=-4(x+1)\\-7x+8=(-4)(x)+(-4)(1)(Distribute)\\-7x+8=-4x+-4$

Add 4x to both sides

$-7x+8+4x=-4x-4+4x\\-3x+8=-4$

Subtract 8 from both sides

$-3x+8-8=-4-8\\-3x=-12$

Divide both sides by -3

$-3x/-3=-12/-3\\x=4$

Justin wants to buy a new bicycle, which costs $266.52. His parents have promised to contribute one-fourth of the cost of the bi

Oliga [24]

Answer:

$199.89

Step-by-step explanation:

The bike costs 266.52

The parents are contributing one fourth of this (1/4)

We need to find 1/4th of 266.52

Divide 266.52 by 4 to find out how much Justin's parents are contributing to the bike

The answer is 66.63

Now subtract 66.63 from 266.52

Justin has to pay a total of 199.89

The weights of bags filled by a machine are normally distributed with a standard deviation of 0.055 kilograms and a mean that ca

Sloan [31]

Answer:

Step-by-step explanation:

Given that the weights of bags filled by a machine are normally distributed with a standard deviation of 0.055 kilograms and a mean that can be set by the operator.

Let the mean be M.

Only 1% of the bags weigh less than 10.5 kilograms

i.e. P(X<10.5) = 0.01

corresponding Z value for P(Z<z) = 0.01 is -0.025

i.e. 10.5 = M-0.025(0.055)

Solve for M from the above equation

M = $10.5+0.025(0.055)\\=10.501375$

Rounding off we get

10.50 kgs

Mean weight should be fixed as 10.50 kg.

Ricky said that two acute angles can be supplementary; but Bobby disagrees. Who is correct? Give an example to prove your argume

saw5 [17]

Answer:

Bobby is correct

Step-by-step explanation:

Acute angles are classified as angles with a measurement of greater than 0° but less than 90°. If you add two acute angles, each as large as possible, the total will be less than 180 degrees.
