Slope 8 ​; through ​(4​,3​)
Reptile [31]

Answer:

y=8x-29

Step-by-step explanation:

Since we know the slope (m) is 8, we can plug it in the slope-intercept formula y=mx+b, making y=8x+b.

Now we need to find the y-intercept (b). To do that, you would need to plug in the points given to you, which were (4,3).

x=4, y=3... so 3=8(4)+b

Now you can solve for the variable b to find the y-intercept.

3=8(4)+b, multiply...

3=32+b, subtract 32 on both sides...

-29=b

Therefore, the y-intercept, or b, is -29.

The equation would be y=8x-29

3 balloon + 2 cakes = £19
horsena [70]

Step-by-step explanation:

3 balloons + 2 cakes = £19

=> 9 balloons + 6 cakes = £57 (multiply by 3)

9 balloons + 6 cakes = £57

- (9 balloons + 3 cakes = £42)

=> 3 cakes = £15, 1 cake = £5.

Therefore 3 balloons + 2(£5) = £19,

3 balloons = £9, 1 balloon = £3.

Hence each balloon is £3 and each cake is £5.

A 22-ft by 28-ft rectangular swimming pool is surrounded by a walkway of uniform width. If the total area of the walkway is 336
aleksklad [387]
1) we calculate the area of  the swimmning pool
area of this swimming pool=(22ft)(28 ftt)=616 ft².

2) we calculte the total area of the swimming pool + area of the walkway
Total area=area of the swimming pool + area of the wakway
Total area=616 ft²+336 ft²=952 ft².

3) we can suggest this equation :
x=width
(22+2x)(28+2x)=952
616+44x+56x+4x²=952
4x²+100x-336=0
x²+25x-84=0

x=[-25⁺₋√(625+366)]/2=(-25⁺₋31)/2
we have two solutions:
x₁=(-25-31)/2=-28 this solution is not valid.
x₂=(-25+31)/2=3

Answer: the width of the walkway is 3 ft.
