Answer = –3/2

Use rise/run to find the gradient, while finding the difference between the two points.

Equation of slope:
y2 - y1 / x2 - x1

-1-2 / 3-1

–3/ 2

Slope = –3/2

Complete the following statements to prove that ∠IKL and ∠JLD are supplementary angles. It is given that ∠EIJ ≅ ∠GJI. Also, ∠EIJ
Dima020 [189]

Answer:

1st blank: substitution property of equality

2nd blank: linear pair theorem

3rd blank: substitution property of equality

Step-by-step explanation:

<u>1st blank</u>

∠EIJ ≅ ∠GJI (eq. 1)

∠EIJ ≅ ∠IKL (eq. 2)

∠GJI ≅ ∠JLK (eq. 3)

Substituting eq. 3 into eq. 1:

∠EIJ ≅ ∠JLK

and then, substituting eq. 2:

∠IKL ≅ ∠JLK

which means that m∠IKL = m∠JLK

<u>2nd blank</u>

The Linear Pair Theorem states that two angles that form a linear pair are supplementary

<u>3rd blank</u>

m∠JLK + m∠JLD = 180°

Substituting with the previous result:

m∠IKL + m∠JLD = 180°

Joel and Kevin are each putting money in a savings account to buy a new bicycle. The amount, in dollars, in Joel’s savings accou
anyanavicka [17]

Given:

The amount of money in Joel’s account is:

j(x)=25+3x

The amount of money in Kevin’s account is:

k(x)=15+2x

To find:

The function that correctly represents how much more money, in dollars, is in Joel’s account than in Kevin’s account x weeks after the start of the year.

Solution:

We need to find the difference between the function j(x) and function k(x).

j(x)-k(x)=(25+3x)-(15+2x)

(j-k)(x)=25+3x-15-2x

(j-k)(x)=(25-15)+(3x-2x)

(j-k)(x)=10+x

Therefore, the correct option is D.

A set of data is normally distributed with a mean of 52 and a standard deviation of 5. What percentage of the data is in the int
Elina [12.6K]
68. The 68-95-99.7 percent rule states that 68% falls within one standard deviation, 95% within 2, and 99.7% within 3. Since the standard deviation is 5, 47 and 57 are both one away, and because of that rule, the answer you need is 68%. Hope this helps.
