Answer:

B. Megan is correct. When two lines have different slopes, they must intersect, producing one solution.

Step-by-step explanation:

A system of two lines has:

No solutions: When both lines have the same slope but a different x and y-intercept.

One solution: When both lines have different slopes.

Infinitely many solutions: When both lines have the same slope and same x and y-intercept.

Since it is given that the lines have different slopes, the equation has only one solution.

We do not need to check the y-intercept.

Megan is correct.

Answer:

Step-by-step explanation:

-4 times -6x is 24x and-4 x -3 = 12

isolating 24x on the right side we subtract twelve on the right and on the left to get 24x=0 and 24 divided by zero is 0

A truck is carrying pear juice, pineapple juice, and grapefruit juice bottles in a ratio of

sweet [91]

Answer:

120

Step-by-step explanation:

We let N be such that

9N = number pear juice bottles,

1N = number of pineapple juice bottles,

2N = number of grapefruit juice bottles.

Then, 20 = 2N, so that N = 10, and

The total number of juice bottles =

9N+1N+2N =

9(10)+1(10)+2(10)=

90+10+20=120

Geometry question, any help is appreciated

kodGreya [7K]

Answer:

Hence, the ratios are given by 5:7, 25:49, 125:343.

Step-by-step explanation:

We are given two spheres such that:

Volume of small sphere $V_{s}$ = 250 $yd^{3}$

Volume of large sphere $V_{l}$ = 686 $yd^{3}$ .

Then the ratio of volume = 250 : 686 = 125 : 343.

Since, the volume of a sphere = $\frac{4 \pi \times r^{3}}{3}$ , this gives us that the ratio of the radius = ∛ $V_{s}$ : ∛ $V_{l}$

i.e. The ratio of the radius = ∛125 : ∛343 = 5 : 7.

Further, as the surface area of a sphere = $4 \pi \times r^{2}$ , this gives us that the ratioof surface area = $r_{s} ^{2}$ : $r_{l} ^{2}$

i.e The ratio of the surface area = $5^{2}$ : $7^{2}$ = 25 : 49

So, the ratio of the surface areas = 25 : 49.

Hence, the ratios are given by 5:7, 25:49, 125:343.

Freddy spent $56.07 on four pairs of jeans at the store. His cost included $4.15 sales tax.

S_A_V [24]

$12.98 each. You would do $56.07 - $4.15. Then divide the answer of that by four.
