Answer:

[tex]y=\frac{10}{7}x+\frac{8}{7}[/tex]

Step-by-step explanation:

Slope-intercept formula:

[tex]y=mx+b[/tex]

Isolate [tex]y[/tex] on one side:

[tex]10x - 7y = -8[/tex]

[tex]\frac{10x}{7} -\frac{7y}{7} =\frac{-8}{7}[/tex]               divide everything by 7 since 7 is the number next to [tex]y[/tex]

[tex]\frac{10x}{7} -y =\frac{-8}{7}[/tex]

We can't simplify it any further, so let us rearrange it.

[tex]y=\frac{10x}{7}-\frac{-8}{7}[/tex]                According to the formula, [tex]y=mx+b[/tex], the y is first

[tex]y=\frac{10}{7}x+\frac{8}{7}[/tex]

Therefore, [tex]y=\frac{10}{7}x+\frac{8}{7}[/tex] is the slope-intercept form.

we know is a right triangle, so one angle must be 90°, we also know is an isosceles, that means it has twin sides, and we also know that the hypotenuse or slanted side is 8, so the triangle must be a 45-45-90 triangle,  Check the picture below.

200 / 5 = 40 minutes a day

Answer:

Step-by-step explanation:

B) the stone hits the water within the first 2 seconds. Because the stone drops at the speed of 88 feet/second, and 88 x 2 is 176. but the bridge is only 135 feet tall.

so,

88 feet/second

176 feet/2 seconds

135 feet means that it reached the river within 2 seconds. it reached the river in 1.545 seconds

a) The formula that models the height of the stone after t seconds is: s(t) = 135 + 88t + 16.1t²

b) No, the stone does not hit the water within the first 2 seconds.

(a) The formula for the height of an object thrown downward with an initial velocity and under the influence of gravity is expressed as:

s(t) = s₀ + v₀t + ¹/₂gt²

where:

s(t) is the height of the stone at time t,

s₀ is the initial height

v₀ is the initial velocity

g is the acceleration due to gravity

We are given:

s₀ = 135 ft

v₀ = 88 ft/s

g = 32.2 ft/s²

Thus:

s(t) = 135 + (88)t + ¹/₂(32.2)t²

s(t) = 135 + 88t + 16.1t²

(b) To check if the stone hits the water within the first 2 seconds, we need to find s(2) and determine if it is less than or equal to 0 (water level).

s(2) = 135 + 88(2) + 16.1(2)^2

s(2) = 135 + 176 + 64.4

s(2) = 375.4 ft

Since the height at t = 2 seconds is 375.4 feet, and this height is above the water level (which is 0 feet), the stone does not hit the water within the first 2 seconds.

Answer:

19.5 cm

Step-by-step explanation:

The median of a data set is the middle number. It can be easily found by crossing out the first value then the ending value, and you keep repeating that pattern. However, in this case, when we cross them out, we're left with the numbers 18 and 21. When we come across a problem like this, we find the mean of 18 and 21 by adding them up and then dividing them by 2. 18 + 21 is 39, and 39/2 is 19.5.

Therefore, the answer is 19.5 cm.

XD is an emoticon commonly used to symbolize dying from laughter. It represents 2 closed eyes with the X and mouth with the D.

The solution of the equations is (-2, -1)

2x - 3y = -1

11x  - 9y = -13

Using elimination method let multiply the first equation by -3.

Therefore,

-6x + 9y = 3

11x - 9y = -13

5x = -10

x = -10 / 5

x = -2

let's find y as follows;

2(-2) - 3y = -1

-4 - 3y = -1

-3y = -1 + 4

-3y = 3

y = 3 / -3

y = -1

Answer:

1/48 cups of sugar in one muffin

Step-by-step explanation:

We're essentially looking for the unit rate.  

Thus, we can simply do (1/2) / 24, which is 1/48.

The quantity of sugar in each muffin is 0.021 cup.

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

Given that, Steven used 1/2 cups of sugar to make 24 muffins.

Quantity of sugar in each muffin = Quantity of sugar/Number of muffins

= 1/2 ÷24/1

= 1/2 ×1/24

= 1/48

= 0.021 cup

Therefore, the quantity of sugar in each muffin is 0.021 cup.
