Answer:

y=52x+b.

Step-by-step explanation:

since point (2,1) satisfies the equation.

Answer:

a+b=6

a-b =4

______subtract

(a-a)+(b-(-b))=6-4

0+2b = 2

b= 1

put the value of b at any equation

a+1 =6

then a=6-1=5

a square+b square= 25+1= 26

Answer:

A. Cosine

Step-by-step explanation:

It is cosine because ADJ/HYP is Cosine in Soh Cah Toa.

The ratio adjacent/hypotenuse shows the Cosine function.

Trigonometric ratios are based on the value of the ratio of sides of a right-angled triangle and contain the values of all trigonometric functions. The trigonometric ratios of a given acute angle are the ratios of the sides of a right-angled triangle with respect to that angle.

We have,

To find the ratio equivalent to Adjacent / Hypotenuse.

We know that the ratio of an angle's perpendicular (opposite) side to its hypotenuse is known as its sine.

and, Cosine of an angle is defined as the ratio of the side adjacent to that angle to the hypotenuse.

or Cosine ratio = Adjacent/ Hypotenuse

Answer:

$600

Equation:

(Base) x (percent as a decimal) x (years) = interest

(B x .16 x 7.5 = 720)

Steps:

(Base) x (percent as a decimal) = (interest) / (years)

(B x .16 = 96)

Base = (interest / years) / (percent as a decimal)

(B = 600)

Answer:

$1200 each month

Step-by-step explanation:

So Craig pays $720 each year, so he pays 720/12 = $60 each month

Since $60 is 1/20 of his monthly income, we multiply 60 by 20

60* 20 = 1200

Craig earns $1200 each month

Answer:

y=3x-36

Step-by-step explanation:

slope must be negative reciprocal

-1/3 changes to +3

then use point slope form with new points TO FIND NEW Y INTERCEPT

y=MX+B

0=3(12) + b

b= -36

new problem is y= 3x-36

Answer:

21/32 gal

Step-by-step explanation:

1 gallon equals 16 cups, so we first need to convert the rate from cups to gallons

1.5cup/1 x 1/16 gal

can be simplified to 3/32 gal

so we now multiply this rate by 7 for a week

so in total it leaks

3/32 x 7/1 = 21/32

Answer:

x = 6

Step-by-step explanation:

150 - x - 2x = 120 + 2x

place the like terms at the same side . So,

150 - x - 2x - 2x - 120 = 0

now add/subtract like terms

30 - 5x = 0

adding 5x on the both sides

30 = 5x

30/5 = x

6 = x

Answer:

Quadratic equation in vertex form: y = 2(x + 3)²+ 0

Step-by-step explanation:

The vertex form of a quadratic equation is:

y = a (x - h)² + k  where:

The value of a determines that the graph opens up or down.  If a is positive, the graph opens up. The value of a also makes the parent function wider or narrower.  

The vertex of the given parabola occurs at point (h, k) where the parabola intersects the axis of symmetry, x = h. It is also determines whether it is either the maximum or minimum point on the graph.

The quadratic equation of the graph in vertex form is: y = 2(x + 3)²+ 0

where:

a = 2

vertex (minimum point) = (-3, 0)

axis of symmetry: x = -3

Distance» 245

Answer:

245 units

Step-by-step explanation:

Anna drives her car at a speed of = 70 kmph

To Find:

How much distance will she cover in 3 hours 30 minutes.

Solution:

We'll use here the formula of Speed,then plug the values which are given.

Speed = Distance/Time

70 = D/7/2

7/2*70 = Distance

7*35 = Distance

Distance = 245

We can conclude that Anna can cover 245 units in 3 hrs 30 mins.

The solution of the inequality ( - 5 / 2 ) ( 3x- 2 )< 6 - 2x. will be x < ( 18 / 11 ).

inequality is the relationship between two expressions that are not equal, employing a sign such as ≠ “not equal to,” > “greater than,” or < “less than.”.

Given inequality will be solved as below:-

( - 5 / 2 ) ( 3x - 2 ) < 6 - 2x

Multiply the other hand by 2 and solve further.

( - 5  ) ( 3x - 2 ) < 2 ( 6 - 2x )

( - 5  ) ( 3x - 2 ) < ( 12 - 4x )

Take like terms to the same side and solve.

-15x + 30 < 12 - 4x

-15x + 4x < 12 - 30

-11x < - 18

x < 18 / 11

Therefore, the solution of the inequality ( - 5 / 2 ) ( 3x- 2 )< 6 - 2x. will be x < ( 18 / 11 ).
