Answer:
Y= 0
Step-by-step explanation:
A proportional relationship is when two numbers change at a constant rate. They always are modeled by y = kx, which in this case, would be y = 5/3x. The y-intercept would be added to the equation, as y = kx + b, in this case would be y = 5/3x + 0, or the previous equation.

The slope of the line will be +10.
What is the general equation of a Straight line?The general equation of a straight line is -
[y] = [m]x + [c]
where -
[m] → is slope of line which tells the unit rate of change of [y] with respect to [x].
[c] → is the y - intercept i.e. the point where the graph cuts the [y] axis.
We have a table that represents a linear function.
We have -
[x] [y]
-2 -8
-1 2
0 -4
1 -10
2 -16
The slope of the function can be calculated as -
m = (2 + 8)/(-1 + 2) = 10/1 = 10
Therefore, the slope of the line will be +10.

Answer:
T = 2
Step-by-step explanation:
1. Distribute
2. Add the numbers
3. Order summands
4. Subtract 10 from both sides of the equation
5. Simplify
Answer:
t=2
Step-by-step explanation:
Simplify both sides of the equation.
16=4+3(t+2)
16=4+(3)(t)+(3)(2) (Distribute)
16=4+3t+6
16=(3t)+(4+6)(Combine Like Terms)
16=3t+10
16=3t+10
Step 2: Flip the equation.
3t+10=16
Step 3: Subtract 10 from both sides.
3t+10−10=16−10
3t=6
Step 4: Divide both sides by 3.
3/2= 6/3= t=2
An architect is drafting a scale drawing of a house for an upcoming project. The customer wants the front of the house to measure 60 feet long. The architect's sketch shows that the front of the house has a length of 15 inches. Determine the factor of dilation used by the architect as he created the scale drawing for his customer. In your final answer, include all of your calculations.
(HINT: The factor of dilation should be a comparison of the same unit of measurement. Convert 60 feet to inches before you begin your calculations.)

Given: AB ≅ BC , AE ≅ FC Prove: m∠AEC=m∠AFC
Answers
Answer:
EC/AB = FC/MA
Step-by-step explanation:
We are given AB
≅
BC that means that side AB and side BC are equal also we know that angle opposite to equalt
sides are equal.
Hence, ∠BAE=∠BCE-------(1)
Also ∠AEB=∠CEB.
Now we are given that: ∠ABC = 130°30’ i.e. in degrees it could be given as:
60'=1°
30'=(1/2)°=0.5°
Hence ∠ABC = 130°30’=130+0.5=130.5°
Also we know that sum of all the angles in a triangle is equal to 180°.
Hence,
∠BAE+∠BCE+∠ABC=180°.
2∠BAE+130.5=180 (using equation (1))
2∠BAE=49.5
∠BAE=24.75° (DIVIDE BOTH SIDE BY 2)
Now in triangle ΔBEC we have:
∠BEC=90° , ∠BCE=24.75°
SO,
∠BEC+∠BCE+∠EBC=180°.
Hence, 90+24.75+∠EBC=180
∠EBC=180-(90+24.75)
∠EBC=65.25°
Now we are given AE = 10 in
Also ∠BEA= 90°.
And ∠BAE=24.75°; hence using trignometric identity to find the measure of side BE.
\begin{gathered}\tan 24.75=\dfrac{BE}{AE}=\dfrac{BE}{10}\\\\BE=10\tan 24.75-------(2)\end{gathered}tan24.75=AEBE=10BEBE=10tan24.75−−−−−−−(2)
similarly in right angled triangle ΔBEC we have:
\begin{gathered}\tan 24.75=\dfrac{BE}{EC}\\\\\tan 24.75=\dfrac{BE}{EC}\\\\EC=\dfrac{BE}{\tan 24.75}------(3)\end{gathered}tan24.75=ECBEtan24.75=ECBEEC=tan24.75BE−−−−−−(3)
Hence, using equation (2) in equation (3) we get:
EC=10 \text{in.}EC=10in.
Hence AC=AE+EC=10+10=20 in.
Hence side AC=20 in.

The expressions that are equivalent are (3²)⁴ and 3⁸.
What are Expressions?Expressions are mathematical statements which consist of two or more terms and terms are connected to each other using mathematical operators like addition, multiplication, subtraction and so on.
The given expression is (3⁷)² . 3⁻⁶
Simplifying the expression, we get,
(3⁷)² . 3⁻⁶ = 3¹⁴ . 3⁻⁶
We have a rule for exponent xᵃ . xᵇ = xᵃ⁺ᵇ
= 3¹⁴⁻⁶
= 3⁸
Consider the expression in the options.
We have (xᵃ)ᵇ = xᵃᵇ
(3²)⁴ = 3⁽²⁾⁽⁴⁾ = 3⁸
And there is a third option 3⁸.
These two expressions are equivalent to the given expression.
Hence the expressions equivalent to the given expression is (3²)⁴ and 3⁸.

A. 3 1/4
B. 3
C. 2 3/4
D. 2 1/4

Answer:
C
Step-by-step explanation:
initial amount: 12 7/8 lbs
ate: 0.75 lbs= 3/4 lbs = 6/8 lbs
used: 9 3/8 lbs
remainder: 12 7/8 - 9 3/8 - 6/8
= 3 1/8 - 3/8

Answers
Answer:
1) Remember to change the signs when necessary. For example, when you're subtracting a negative with another negative, you add the two numbers to form a bigger negative.
2)
1)) -6 + 11 = 5
2)) -6 + 21 = 15
3)) 5 + 0 = 0
4)) 19 + 19 = 38
5)) (-5) + (-3)
6)) -87 + 87 = 0
7)) -1 + -17 = -18
3) Tom didn't change the sign to make a +, instead he left it as one negative sign and a subtraction sign.
4) The answer will be of a greater value as the two negatives would cancel each other out. For example, -9 - (-9) would end up being 0 as the sign change would make one 9 positive.
5) $-4 + $29 = $25 He added $29 dollars to his bank account, turning himself out of debt.
