Step-by-step explanation:

[tex]15) f(x) = 10-\dfrac{9}{2}x\\10-\dfrac{9}{2}x = -53\\\\-\dfrac{9}{2}x=-53-10\\\\\dfrac{-9}{2}x= - 63\\\\x = -63*\dfrac{2}{-9}\\\\x = 7*2\\\\x = 14[/tex]

[tex]17) \dfrac{1}{8}y = \dfrac{-3}{4}x - 1\\\\Multiply \ the \ entire \ equation \ by \ 8\\\\8*\dfrac{1}{8}y=8*\dfrac{-3}{4}x-1*8\\\\\\y = 2*(-3)x-8\\\\y = -6x - 8\\\\6x + y = -8\\[/tex]

[tex]18) 5y = 35 + 10x\\\\\dfrac{5y}{5}=\dfrac{35}{5}+\dfrac{10x}{5}\\\\y = 7+2x\\\\-2x + y = 7\\\\[/tex]

[tex]19)x -4y = 28\\\\ -4y = -x + 28\\\\\dfrac{-4y}{-4}=\dfrac{-x}{-4}+\dfrac{28}{-4}\\\\\\y = \dfrac{1}{4}x-7[/tex]

x = 0 ; y = 0 - 7 = -7          (0 .-7)

[tex]x = 4 ; y = \dfrac{1}{4}*4-7 = 1 - 7 = -6 ; (4 , -6)\\\\\\x = -4 ; y = \dfrac{1}{4}*(-4) - 7 = -1 - 7 = -8 ; (-4,-8)[/tex]

Plot the points (0,-7)  , (4,-6) and (-4 , -8) in the graph and join the points

Step-by-step explanation:

Answer:

c ^ 2 * r ^ 2

Step-by-step explanation:

T is proportional to c * k * s^2

T is proportional to c * (k / r^2) * s^2

T is proportional to k * c ^ 2 * s ^ 2

T is proportional to infinity

The correct formula would be T is proportional to c ^ 2 * r ^ 2. This indicates that the temperature of the object is directly proportional to the inverse square of the distance from the center of the sun. This is because energy received decreases as the inverse square of the distance.

The line has a slope of -6 and a y intercept of 7.

The linear equation is given by:

y = mx + b;

where m is the slope of the line, b is the y intercept, y, x are variables.

The equation of the line passing through the points (6.-29) and (-4,31) is:

[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)\\\\y-(-29)=\frac{31-(-29)}{-4-6}(x-6)\\\\y+29=-6(x-6)\\\\y=-6x+7[/tex]

Hence the line has a slope of -6 and a y intercept of 7.

Answer:

u = < 25, - 15 >

Step-by-step explanation:

To find u subtract the coordinates of the terminal point from the coordinates of the initial point.

u = < 8 - (- 17) , - 11 - 4 > = < 8 + 17, - 15 > = < 25, - 15 >

Multiply 1 & 2 from 3 and 4 respectively and add to get product.

Answer:

18 and 6

Step-by-step explanation:

The sum of two numbers is twice their difference: 18 + 6 = 24, 18 - 6 = 12. 24 is twice of 12.

The larger number is 5 more than twice the smaller. Twice of 6 is 12. 5 more than 12 is 18.

Answer/Step-by-step explanation:

"Side AB is parallel to side DC so the alternate interior angles, angle ABD and angle CDB, are congruent." True

"Side AB is equal to side DC and DB is the side common to triangles ABD and BCD."  True

Now we have 2 triangles, with 2 congruent sides, and the angles between these pairs of congruent sides, are also congruent..

This means that:

Therefore, the triangles ABD and CDB are congruent by SAS postulate, NOT SSS postulate, which would require 3 pairs of congruent sides.

Answer: Triangles ABD and CDB are congruent by the SAS postulate.

Answer:

(2,-9)

Step-by-step explanation:

Multiply out the polynomial to get:

x^2-4x-5

the vertex formula is -b/2a (use the coefficients of the equation above)

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

we know the x value of the vertex is 2. Now we can plug that into the original equation to get the y value.

(2-5)(2+1)

(-3)(3) = -9

so the coordinate is (2,-9)

Answer:

so you're going to need to find the slope. in order to do that use (y2-y1)/(x2-x1)

(7-(-2))/(0-8)

simplify

9/-8

simplify -9/8

now using y=mx+b, we need to find b. so we can plug in the coordinates of (0,7) or (8,-2). let's use (8,-2) because it involves more math.  

y=mx+b

-2=(-9/8)(8)+b

multiply (-9/8) by 8 to get -9

-2=-9+b

add 9 to both sides

7=b

so our equation is now

y=-(9/8)x+7

Step-by-step explanation:

Answer:

y=-(9/8)x+7

Answer:

it is 64 m long is making me type 20 letters

Step-by-step explanation:

Normally we write equation of functions like this: f(x) = x - 5

When we say f(5) = 7, we are implying that the x is 5.

The equation could look something like this: f(x) = x + 2

In this case, if you put x as 5, you will get 7 or 5 + 2

Means that 5 times of f equals to 7
