\blue{\textsf{\textbf{\underline{\underline{Question:-}}}}

          What is the equation of the line in slope intercept form if its slope is 8 and its y-intercept is -3?

\blue{\textsf{\textbf{\underline{\underline{Answer:-}}}}

y=8x-3

\blue{\textsf{\textbf{\underline{\underline{How to solve:-}}}}

Slope Intercept form, as the name implies, has slope & intercept in its equation.

It looks like y=mx+b, where "m" is the slope and "b" is the y-intercept.

To determine the equation of the line, we need to write the value of m, which in this case is 8, in lieu of m:-

y=8x+b

Same with the y-intercept:-

\tt{y=8x+(-3)}

Which simplifies to

\tt{y=8x-3}

<h3>Good luck.</h3>

The values are x=8 and y=10

Explanation:

From the figure, we can see that the two quadrilaterals are similar.

Thus, by the property of quadrilateral, for similar quadrilaterals, their corresponding angles and sides are congruent. Thus, we have,

∠D = ∠S, ∠E = ∠P, ∠G = ∠R and ∠F = ∠Q

Also, GF = QR and DE = PS

Where QR = 2x-4 and ∠D = 102°, ∠G = 84° and ∠F = 68°, ∠Q = (6y+x)°

Hence, to determine the value of x for the side QR, we have,

Equating the values in GF = QR,we get,

12=2x-4\\16=2x\\8=x

Thus, the value of x is 8.

Substituting x in the angle Q to determine the value of y.

Thus, we have,

∠F = ∠Q

68=6y+x\\68=6y+8\\60=6y\\10=y

Thus, the value of y is 10.

Hence, The values are x=8 and y=10

A tv costs £800 plus VAT at 20% what is the total cost of the tv?
slamgirl [31]

hello friend ☺

Given :

TV cost = 800 £

VAT = 20 %

Amount of VAT

= 20% of 800

= 800 × 20 /100

= 160 £

So Total cost of TV

= original price + VAT

= 800 + 160

= 960 £

Thanks ❤

Use the figure to find the measures of the numbered angles. ∠5 = ∠6 =
Gwar [14]

Answer:

∠ 5 = 49°, ∠ 6 = 131°

Step-by-step explanation:

∠ 5 and 49° are corresponding angles and are congruent, then

∠ 5 = 49°

∠ 5 and ∠ 6 are adjacent angles and are supplementary, sum to 180° , that is

∠ 6 + ∠ 5 = 180°

∠ 6 + 49° = 180° ( subtract 49° from both sides )

∠ 6 = 131°

Three different equations that have x=5 as a solution
gulaghasi [49]

Answer:

The easiest ways to do this is to add, subtract, multiply, or devide 5 from a number, do that operation to x, and set that number as the equivelent.

For example

3 * 5=15

so

3x=15
