In 10 years Clayton will be three times older than Sarah is now.
What is a numerical expression?A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.
Given, Sarah is 5 years old and Clayton is x years older than Sarah.
∴ Clayton is (x + 5) years old.
So, In (x + 5) = 3×5 years Clayton will be three times older than Sarah is now.
∴ (x + 5) = 15.
x + 5 = 15.
x = 15 - 5.
x = 10.

Answer:
[tex] \huge{ \boxed{ \bold{ \tt{2 \sqrt{26}}} \: \: \text{units} } } [/tex]
♁ Question :Find the distance between ( 5 , -6 ) and ( 3 ,4 ).♁ Step by step explanation:Let the points be A and B. Now,
Let, A ( 5 , -6 ) ⇢ ( x₁ , y₁ )Let, B ( 3 , 4 ) ⇢ ( x₂ , y₂ )Use the distance formula to determine the distance between A ( 5 , -6 ) and B ( 3 , 4 ).
[tex] \boxed{ \underline{ \sf{distance = \sqrt{ {(x2 - x1)}^{2} + {(y2 - y1)}^{2} } }}}[/tex]
Substitute the actual value of the points into the distance formula and then simplify.
[tex] \dashrightarrow{ \sf{ \sqrt{ {(3 - 5)}^{2} + {(4 - ( - 6))}^{2} } }}[/tex]
Remember : The positive and negative integer are always subtracted but posses the sign of the bigger integer.
[tex] \dashrightarrow{ \sf{ \sqrt{ {( - 2)}^{2} + {(4 - ( - 6))}^{2} } }}[/tex]
Remember : ( - ) × ( - ) = ( + )
[tex] \dashrightarrow{ \sf{ \sqrt{ {( - 2)}^{2} + {(4 + 6)}^{2} } }}[/tex]
Add the numbers : 4 and 6
[tex] \longrightarrow{ \sf{ \sqrt{ {( - 2)}^{2} + {(10)}^{2} } }}[/tex]
Evaluate the power

Therefore , The distance between ( 5 , -6 ) and ( 3 , 4 ) is [tex] \sf{2 \sqrt{26}} [/tex] units .

Write the expression as the
sine or cosine of an angle.
Answer:
sine(pie/5+pie/2)
Step-by-step explanation:
The expression, written as the sine of an angle is sin (7π/10)
Trigonometry Identities
From the question, we are to write the given expression as the sine or cosine of an angle.
The given expression is
sin(π/5)cos(π/2) + sin(π/2)cos(π/5)
Let A = π/5
and
B = π/2
Thus, we get
sinA cosB + sinB cosA
From the given information, we have that
sin(A ± B) = sinA cos B ± cosA sinB
∴ sin(A + B) = sinA cos B + cosA sinB
Now,
sinA cosB + sinB cosA = sinA cosB + cosA sin B
∴ sinA cosB + sinB cosA = sin (A + B)
Put A = π/5
and
B = π/2
sinπ/5 cosπ/2 + sinπ/2 cosπ/5 = sin (π/5 + π/2)
sinπ/5 cosπ/2 + sinπ/2 cosπ/5 = sin (7π/10)
Hence, the expression, written as the sine of an angle is sin (7π/10)

Answer:
C(-2,-5).
Step-by-step explanation:
FOR A CLOCKWISE 270° ROTATION:
Given point A(x,y) its image is given
as A`(y,-x).
For the image of C which is C`(-5,2)
Comparing this to A`(y,-x)
y = -5 and -x = 2,x = -2
hence C compared to A(x,y)
will be C(-2,-5).
Struggling to do my math work haha please help. Worth 14 points!!!
Answer:
C. y = -1/2 + 2
Step-by-step explanation:
First, we need to find the Slope.
Points: ( -4,4) and (8,-2)
Formula: m = y2 - y1/x2 - x1
m = y2 - y1/x2 - x1
m = -2 - 4/8 - (-4)
m = -6/8 + 4
m = -6/12
m = -1/2
Alright, now that we have the Slope, we can now use the Slope Form to find the Slope Intercept Form.
Point: (8,-2) (You may choose any points, but I would like to choose these for no reason)
Slope: -1/2
Formula: y - y1 = m(x - x1)
y - y1 = m(x - x1)
y - (-2) = -1/2(x - (8))
y + 2 = -1/2x + 4
y = -1/2 + 4 - 2
y = -1/2 + 2
The Slope Intercept Form is: y = -1/2 + 2

What is the point-slope form of an equation for a line that passes through the point (5, –5) with the slope of 2?
Answer:
y + 5 = 2(x - 5)
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
Here m = 2 and (a, b) = (5, - 5) , thus
y - (- 5) = 2(x - 5) , that is
y + 5 = 2(x - 5)
find the difference. (12m + 1) - (5m - 4)
Answer:
7m + 5
Step-by-step explanation:
1) Simplify.
(12m + 1) - 1 (5m - 4) -> (12m + 1) - 5m + 4
2) Eliminate unnecessary parenthesis.
(12m + 1) - 5m + 4 -> 12m + 1 - 5m + 4.
3) Combine like terms.
12m - 5m = 7m, 4 + 1 =5 -> 7m + 5
The solution is 7m + 5

2x - 6y = - 24 and x + -5y = -22
by substitution
Answer:
2x-6y=-24
2x=-24+6y
x=-24+6y÷2
x=-12+3y equation 1
x+(-5y)=-22
-12+3y-5y=-22
-13-2y=-22

A farmer has enough feed to last his 15pigs for 20days. How long would the feed last if he had 10pigs
40/3 days, (13.33 days)
Step-by-step explanation:
Set up the equation, 15/20 = 10/x, and then use cross mutiply to solve it.
10 * 20 = 15x, x = 200/15 = 40/3
Why?
b/c if each pig eats the same amount of food, then the ratio between the number of pigs and days should remain constant.

As the slope is -2, so the rate of change of the function is:
rate of change of function = -2Step-by-step explanation:
The slope is basically the rate of change of a function.
Let us take the two points from the graph
(0, 5)(4, -3)Taking the slope between two points to determine the rate of change of a function
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
