Answer 1

Answer:

D (4.34,3.22)

Step-by-step explanation:

Line Y (2,4), (-4,6)

**y=mx+b   slope-intercept form

  m=slope; b=y-intercept

[tex]m_Y=(6-4)/(-4-2)=2/-6=(-1/3)\\y=-1/3x+b[/tex]

plug in 1 point

[tex]4=-1/3(2)+b; b=14/3[/tex]

Line Z (8,8) (-5,9)

[tex]m_Z=(8-(-9))/(8-(-5))=17/3\\y=(17/3)x+b\\8=17/3(8)+b; b=-32/13\\[/tex]

Substitution

[tex]-\frac{1}{3} x +\frac{14}{3}=\frac{17}{13}x-\frac{32}{13} : x=139/32\\y=-\frac{1}{3}(\frac{139}{32})+\frac{14}{3}\\ : y=103/32[/tex]

in a trivia game, you lose point for wrong answers. You answer the first 5 questions incorrectly. Your score after the 5 questions is -90. How many points is each incorrect answer worth?

Answers

5x=-90. Set up this linear equation and solve for x. Which in this case all you have to do is divide, divide 5 on both sides. 5x/5=x. -90/5=-18. X=-18. Now check your answer by plugging back into the original equation. 5(-18)=-90=-90. Checks out. Hope this helps!

Sarah had 6 yards of ribbon. She needs 1 1/4 yards of ribbon for her project. How many complete ribbons can she cut from the 6 yards

Answers

Answer:

4 complete ribbons

Step-by-step explanation:

From the above question,

We can deduce that a project = complete ribbons

Hence,

1 1/4 yards = 1 complete project

6 yards = x

Cross Multiply

1 1/4 yards × x = 6 yards × 1 complete project

x = 6 yards ÷ 1 1/4 yards

x = 6 yards ÷ 5/4 yards

x = 6 yards × 4 yards/5

x = 24 /5

x = 4 4/5 complete projects(ribbons)

Therefore, she can cut 4 complete ribbons from 6 yards

Four points are drawn on the coordinate plane and connected with straight lines to form a rectangle. Three of the
vertices of the rectangle are located at (2, 1), (2,4), and (-4,4).
a. What are the coordinates of the fourth vertex of the rectangle?
b. What are the dimensions of the rectangle?
c. What is the area of the rectangle?



Answers

Answer:

Step-by-step explanation:

the two diagonals of a rectangle have the same middle point

middle point

x = (2-4)/2 = -1

y = (1+4)/2 = 5/2

The diagonal BD must have the same middle point, so we can find vertex D in this way

(x +2)/2 = -1

x+2 = -2

x = -4

(y+4)/2 = 5/2

y+4 = 5

y = 1

fourth vertex :  (-4, 1)

2) for find the first dimension we can use this formula

|y2 - y1| = |4-1| = 3

for find the second we can use this one:

|x2-x1| = |-4-2| = |-6| = 6 (a dimension can’t be negative)

3)

A = dimension 1 x dimension 2 =  3 x 6 = 18

a= 10 divided by sin(48)= 13
b=cos(48)x13=9

Answer:

a = 14.9; b = 11.1

Step-by-step explanation:

SOHCAHTOA:

Sine = Opposite / Hypotenuse

Cosine = Adjacent / Hypotenuse

Tangent = Opposite / Adjacent

[tex]cos48[/tex]° : adjacent is 10, and hypotenuse is a

    [tex]cos48=10/a; a*cos48=10;a=10/cos48[/tex]

    type 10/cos48 into calculator to get a = 14.9

[tex]sin48[/tex]° : opposite is b, and hypotenuse is a

    [tex]sin48=b/a; sin48=b/14.9; b=14.9*sin48[/tex]

    type 14.9*sin48 into calculator to get b = 11.1

Step-by-step explanation:

Using the addition formula for sine

sin(A + B) = sinAcosB + cosAsinB

Given

sin105°cos35° + sin35°cos105°

= sin105°cos35° + cos105°sin35° ← right side of expansion above

A restaurant meal for a group of people cost $85 total. This amount included a 6% tax and an 18% tip, both based on the price of food. Which equation could be used to find f, the cost of the food?

Answers

The equation that should be used is
$85 = f + 6% + 18%

6% = $5.10
18% = $14.40

$5.10 + $14.40 = $19.50

$85 - $19.50 = 65.50

The cost of the food would have been around $65.50
