Answer:

x = 1.07

Step-by-step explanation:

13 ( 6x - 9) = -33

78x - 117 = -33 ( opening brackets and multiplying )

78x = 84 ( - 117 taken to the other side makes it positive)

x = 84 / 78

x = 1.07

Step-by-step explanation:

$tan \: 48 \degree = \frac{x}{61} \\ \\ 1.11 = \frac{x}{61} \\ \\ x = 1.11 \times 61 \\\\ x = 67.7 feet\:$

A quadrilateral-shaped land property is drawn on a coordinate grid. Two adjacent sides of the property lie along the lines y = 4

Liono4ka [1.6K]

Answer:

P(-4,-8)

Step-by-step explanation:

Given two lines:

$y = 4x + 8;$ and $ \\y = -0.25x - 9$

To determine the point of intersection P of the lines, we equate the two lines and solve for (x,y).

$4x + 8= -0.25x - 9\\4x+0.25x=-9-8\\4.25x=-17\\$Divide both sides by 4.25$\\x=-4\\$Recall:$\\y = 4x + 8\\=4(-4)+8\\=-16+8\\=-8$

Therefore, the intersection point P of the lines is: P(-4,-8)

Dinesh thinks that the point (1,3) is on the line y = 4x - 2.

olga_2 [115]

To see if the point is on the line, plug in one of the point values to see if it equals out.

y = 4x - 2 I will plug in 1 for x to see if y does = 3

y = 4(1) - 2

y = 4 - 2

y = 2 so (1, 2)

Dinesh is not correct because the point on the line when x = 1 is (1, 2) not (1, 3)

Solve the system of linear equations y=-x y=3x-4

andreev551 [17]

For this equation you will have to substitute the y for (-x)
Therefore,
-x=3x-4
-x-3x=-4
-4x=-4
-4x/-4=-4/-4
X= 1
