Answer:

System of Linear Equations with No Solutions

The red line is the graph of y=4x+ 2, and the blue line is

the graph of y=4x+5. When two equations have the

same slope but different y-axis, they are parallel. Since

there are no intersection points, the system has no

solutions.

hope it help ❤️

Find the maximum value of c=4x+2y 2x+2y less than or equal to 10 3x+y less than or equal to 9

svp [43]

Answer: 14

Step-by-step explanation:

Step 1: Graph both equations to find the vertices (see attached):

The graph shows vertices at: (0, 0), (3, 0), (0, 5) and (2, 3)

Step 2: Input the coordinates of the vertices into the given function (c = 4x + 2y):

(0, 0): 4(0) + 2(0) = 0
(3, 0): 4(3) + 2(0) = 12
(0, 5): 4(0) + 2(5) = 10
(2, 3): 4(2) + 2(3) = 14

Step 3: Evaluate the value from Step 2 to find the maximum (largest).

the largest value between {0, 12, 10, 14} is 14

Sams dog weighs 72 pounds the vet suggests that for the dogs health its weight should decrease by 12.5 percent According to the

rewona [7]

Answer:

63.1 pounds

Step-by-step explanation:

1. Change the percentage into a decimal.

12.5% ↔ .125

2. multiply the percentage as a decimal with 72.

72x.125= 9 (this is the same as what is 12.5% of 72)

3. Subtract the number you just got from 72

72-9= 63

Find a linear equation that is perpendicular to y= 2x + 4 and passes through (-5, -3)

Trava [24]

Answer:

y=-1/2x+7/2

Step-by-step explanation:

two lines are perpendicular if the product of the slopes is equal to -1

the slope for y=2x+4 is 2

2*x=-1

x=-1/2

the formula for the slope is

(y2-y1)/(x2-x1)=m

we know y1 and x1

(y+5)/(x+3)=-1/2

y+5=x+3/2

2y+10=x+3

2y=x-7

y=-1/2x+7/2

Alan needs to manufacture a circular metal plate with a perimeter of `10pi` centimeters. If the allowed error tolerance in the p

AnnZ [28]

The ideal radius Alan must control is $\frac{1}{2\pi }$ cm.

<h3>Define perimeter of circle.</h3>

The measurement of the circle's perimeter, also known as its circumference, is called the circle's boundary. The area of a circle determines the space it takes up. A circle's diameter is equal to the length of a straight line traced through its center. Usually, it is stated in terms of units like cm or m.

Given data -

Perimeter of circular plate = 10 $\pi$ cm

We know that perimeter of a circle is 2 $\pi$ r

Therefore 10 $\pi$ = 2 $\pi$ r

r = 5 cm

The given error Alan can make is +-1 cm.

Minimum radius is given by

2 $\pi$ r = 10 $\pi$ - 1

r = $\frac{10\pi - 1 }{2\pi }$

r = 5 - $\frac{1}{2\pi }$

Maximum radius is given by

2 $\pi$ r = 10 $\pi$ + 1

r = $\frac{10\pi + 1 }{2\pi }$

r = 5 + $\frac{1}{2\pi }$

The ideal radius Alan must control is $\frac{1}{2\pi }$ cm.

Isaiah puts a 10 gram weight on a pan balance.how many 1-gram weights does he need to balance the scale

Vikki [24]

Isaiah puts a 10 gram weight on a pan balance. To balance the scale, he needs to put 10 pieces of 1 gram weights which will be equivalent to 10 grams of weight. Hope this answers the question. Have a nice day.
