7 3/4 - 2 2/5
(7-2)+(3/4-2/5)

Answer:

5 7/20

Step-by-step explanation:

basically, you are going to want to turn these into improper fractions

7 3/4 = 28/4 + 3/4

        = 31/4  (no further simplification)

2 2/5 = 10/5 + 2/5

         = 12/5

now get common denominator to subtract

31/4 - 12/5

155/20 - 48/20 = 107/20

if you want this back into mixed fraction then convert

107/20 = 5 7/20

Hey there,

Your question states: <span>The coordinates of A, B, and C in the diagram are A(p, 4), B(6, 1), and C(9, q). Which equation correctly relates p and q? 

Your correct answer would be </span><span>D. p − q = 7 BECAUSE . . .we would have to back the number up because we would need to basically subtract </span>P-Q which would give you 7. So D.) would be your answer.

Hope this helps.

The line L passes through the points (5, -5) and (1, 2).<br> Find the gradient of line L.
Free_Kalibri [48]

gradient of L = -7/4

Explanation:

\sf gradient = \dfrac{y_2-y_1}{x_2-x_1}

<u>Insert the following values.</u>

\rightarrow \sf \dfrac{2-(-5)}{1-5}

\rightarrow \sf \dfrac{7}{-4}

\rightarrow \sf -\dfrac{7}{4}

Can someone help assist me on this Honors Algebra 2 Problem? Challenge Problems #6. The distance from a point on the curve y=√x
ahrayia [7]

Answer:  (0, 0) & (3, √3)

<u>Step-by-step explanation:</u>

Since we need a distance of 2, I graphed y = √x and then drew a circle at center (2, 0) and radius of 2 to see where they intersect.

The coordinates of intersection can be determined by solving a system of equations.

Equation 1: y = √x

Equation 2: (x - 2)² + y² = 2²

I will use the Substitution method with Equation 2 to solve for x:

(x - 2)² + (√x)² = 2²        substituted y with √x

x² - 4x + 4 + x = 4           expanded binomial

x² - 3x + 4 = 4                 added like terms

x² - 3x = 0                       subtracted 4 from both sides

x(x - 3) = 0                       factored

x = 0     x - 3 = 0             applied Zero Product Property

            x = 3

Next, solve for y using Equation 1:

x = 0:    y = √0 = 0

x = 3:    y = √3

Coordinates of intersection are: (0, 0) & (3, √3)

Brainliest for correct answer!!
satela [25.4K]

Answer:

Step-by-step explanation:

Use the distance formula:

d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2} For us that will look like this:

d=\sqrt{(6-(-3))^2+(-2-4)^2} which simplifies to

d=\sqrt{(9)^2+(-6)^2} and a bit more to

d=\sqrt{81+36} so

d=\sqrt{117}
