Y’all I need help asap. I also need to show my work for this so if you can find the slope AND explain how that would be AMAZING

DochEvi [55]

Answer:

Step-by-step explanation:

Slope = rise/run

pick two points, (0,2) (3, -7)

take their y values and subtract them

take their x values and subtract them

2-(-7) over 0-3 is 9/-3

simplify

What is the equation of the line that passes through the point (4,3) and has a slope of 1?

Mamont248 [21]

Answer (assuming it can be in point-slope form):

$y-3 = 1(x-4)$

Step-by-step explanation:

Use the point-slope formula $y-y_1 = m (x-x_1)$ to write the equation of the line. Substitute real values for $m$ , $x_1$ , and $y_1$ in the formula.

Since $m$ represents the slope, substitute 1 in its place. Since $x_1$ and $y_1$ represent the x and y values of a point the line intersects, substitute the x and y values of (4,3) in its place. Substitute 4 for $x_1$ and 3 for $y_1$ . This gives the following equation and answer in point-slope form:

$y-3 = 1(x-4)$

What is the solution of Vx2+49 V x2+49 - x+5?

balu736 [363]

Answer:

x = $\frac{12}{5}$

Step-by-step explanation:

Given,

$\sqrt{x^{2}+49 } = x + 5$

Squaring on both L.H.S. and R.H.S.

$\sqrt{(x^{2}+ 49 )} ^{2} = (x + 5)^{2}$

By expanding L.H.S. we get x² + 49

By expanding R.H.S. we get x² + 10x + 25

x² + 49 = x² + 10x + 25

x² will be subtracted:

49 = 10x + 25

Variables are to be arranged:

10x = 49 - 25

10x = 24

x = $\frac{24}{10}$

∴ x = $\frac{12}{5}$

an umbrella is made by stitching 10 triangular pieces of cloth of two different colours where each pieces measuring 48cm,48cm,an

mars1129 [50]

Answer:

Step-by-step explanation:

first we need to calculate the area of isosceles triangle having sides 48cm, 48cm and 30cm

a = 48

b= 30

Area of isosceles triangle using only sides = ½[√(a^2 − b^2 /4) × b]

= 1/2*30√( 48² - 1/4×30²)

=1/2*30√ (2304 -225)

=684sq cm

cost required to make umbrella= 10*684*5

= 34200
