Leah is writing an equivalent equation which solves for y. What should be her next step?

3 x + 4 y = 8. 3 x minus 3 x + 4 y = 8 minus 3 x. 4 y = 8 minus 3 x.

Add 4y to both sides of the equation.
Subtract 4y from both sides of the equation.
Multiply both sides of the equation by 4.
Divide both sides of the equation by 4

line w passes through point (-6,-7) and has a slope 1/2. what is the equation for the line in point-slope form?

Answers

Answer:

y + 7 = [tex]\frac{1}{2}[/tex] (x + 6)

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b ) a point on the line

Here m = [tex]\frac{1}{2}[/tex] and (a, b ) = (- 6, - 7 ) , then

y - (- 7) = [tex]\frac{1}{2}[/tex] (x - (- 6) ) , that is

y + 7 = [tex]\frac{1}{2}[/tex] (x + 6)

The required equation is ~

[tex] \boxed{ \sf{y = \frac{x}{2} + 2 }}[/tex]

[tex] \large \boxed{ \mathfrak{Step\:\: By\:\:Step\:\:Explanation}}[/tex]

Let's find the slope of given line ~

[tex]y = - 2x + 5[/tex]

comparing it with general slope - intercept form of line (y = mx + c) we get, m = -2 (that is slope of the line)

let the slope of the required line be n

And, now since the required line Is perpendicular to the given line. the product of their slopes is -1

that is ~

[tex] - 2 \times n = - 1[/tex]

[tex]n = \dfrac{ - 1}{ - 2} [/tex]

[tex]n = \dfrac{1}{2} [/tex]

slope of required line is ~ 1/2

now, let's use the point - slope form of line to find the equation of required (perpendicular) line (using point (0 , 2) ~

that is ~

[tex]y - y_1 = m(x - x_ 1)[/tex]

here, m = slope ~

[tex] y - 2 = \dfrac{1}{2} (x - 0)[/tex]

[tex]y - 2 = \dfrac{x}{2} [/tex]

[tex]y = \dfrac{x}{2} + 2[/tex]

y = –16x2 + 119x + 57

Answers

Answer:

7.89 seconds

Step-by-step explanation:

using the quadratic formula (-b+-√(b^2-4ac))/2a

a=-16 b=119 c=57

x=-0.451

and

x=7.889

time cant be negative so use the positive x

Time required for the rocket to hit the ground would be 7.9 s.

What is a quadratic equation?

A quadratic equation is the second-order degree algebraic expression in a variable. the standard form of this expression is  ax² + bx + c = 0 where a. b are coefficients and x is the variable and c is a constant.

We are given the quadratic equation as;

-16x² + 119x + 57 = 0

By using the quadratic formula,

x = [-b ± √b² - 4ac]/2a

Here, a = -16, b = 119 and c = 57

b² - 4ac = (119 )² - 4(-16)(57)

= 14161 + 3648

= 17809

So, x = [-(119) ± √17809]/ 16(2)

= (-119 ± 133.4)/32

Therefore, the time is 7.9 s.

Find the perimeter of a rectangle whose length is 12 longer than its width
with an area of 45 square feet. To earn 5 points write the mathematical
sentence, the value of Length, width and perimeter

Answers

Answer:

l = 21

w = 9

P = 60

Step-by-step explanation:

l = 12 + w

A = l*w = 45

substitute l = 12 +w

45 = (12 + w) * w

45 = 12w + w^2

w^2 + 12w - 45 = 0

w^2 + 2*6*w +36 = 45 + 36 (added 36 on both sides 6^2)

(w + 6) ^2 = 45+36 = 81

w + 6 = +-9

As width cannot be negative w = 9

so l = 12 + 9

= 21

Perimeter = P = 2 (l + b)

= 2 ( 21 + 9)

= 2 (30)

= 60

Evaluate the expression.

2−[(2+10(−1)÷2)+1]

What is the value of the expression?

Answers

Answer:

4

Step-by-step explanation:

Review

To evaluate the expression, lets use BODMAS. Before we get to the solving part, lets revise BODMAS.

=> B in BODMAS is brackets. This means that whatever operations are inside a bracket, we must solve that first.

=> O in BODMAS is Orders. The O is used very rarely, there is a possibility that there is no powers, exponents.

=> D in BODMAS is Division. This means that whatever division is occurring in the expression must be done first (Unless if there is a bracket).

=> M in BODMAS is Multiplication. This means that whatever multiplication is occurring in the expression must be done next.

=> A in BODMAS is Addition. This means that whatever addition is occurring in the expression must be done then.

=> S in BODMAS is Subtraction. This means that whatever subtraction is occurring in the expression must be done last.

Solution:

Now, lets get to the point. We need to find the expression '2−[(2+10(−1)÷2)+1]'. Using the help of BODMAS, we can solve it.

Step 1: Simplify the innermost bracket.

2 − [( 2 + 10(−1)÷2)+1]

=> 2-[(2-10÷2)+1]

Note: Since in the innermost bracket there is no operation, we can open the innermost bracket and get along with the second inner bracket.

Step 2: Simplify the second inner bracket.

=> 2 - [(2 - 10 ÷ 2) + 1]

=> 2 - [(2 - 5) + 1]

=> 2 - [(-3) + 1]

=> 2 - [-3 + 1]

Step 3: Simplify the third inner bracket.

=> 2 - [-3 + 1]

=> 2 + 2

Step 4: Solve.

=>  2 + 2

=> 4

Triangle R S T is shown. Angle R S T is a right angle. The length of R S is 10, the length of R T is 26, and the length of S T is 24. Use the diagram and side lengths of triangle RST to determine the angles used for the trigonometric ratios. sin( ) = Twelve-thirteenths tan( ) = Five-twelfths

Answers

Answer:

sin(R) = 12/13tan(T) = 5/12

Step-by-step explanation:

The mnemonic SOH CAH TOA is intended to remind you of the relationship between sides of a right triangle and trig functions of the acute angles. It tells you ...

  Sin = Opposite/Hypotenuse

  sin(R) = 24/26 = 12/13

and ...

  Tan = Opposite/Adjacent

  tan(T) = 10/24 = 5/12

Answer: SIN = R and TAN = T
