Step-by-step explanation:

Answer:

EF=35

EG=22

Step-by-step explanation:

EF

7y-14=2y+21

5y=35

y=7

EF=7(7)-14=49-14=35

EG

15x+7=12x+10

3x=3

x=1

EG=15(1)+7=15+7=22

Answer:

(a). 35 units ; (b). 44 units

Step-by-step explanation:

(a). 7y - 14 = 2y + 21 ⇒ y = 7

EF = 7(7) - 14 = 35 units

(b). EJ = JG

15x + 7 = 12x + 10 ⇒ x = 1

EG = 2 × (15(1) + 7) = 44 units

Answer:

1. 1/2, 2. 2, 3. 1/-3, 4. -2

Step-by-step explanation:

1) I know that the equation for slope is y2-y1/x2-x1. For number one I first found two points of the graph which is (0,3) and (2,4) (not sure if I see it correctly, its kind of blurry). I decided that (0,3) would be my y1 and x1 and (2,4) will be my y2 and x2. I later plugged the number in the equation and got 4-3/2-0 which the answer turns out to be 1/2.

2) For the rest of the questions it is kinda the same business as question 1. For question two I chose two points out of the table which wrer (-1, -12) and (1,-8) and plugged them into the equation and got -8-(-12)/1-(-1) which the answer turns out to be 2.

3) similar to question 2. The two points(2,-6) and (-4,-3) are given to you. so I plugged them in again and got -3-(-6)/-4-2 which the answer turns out to be 3/-6 into 1/-3.

4) Same with question 1 find two points of the graph. I chose (0,3) and (1,1) (again might not be accurate it's kind of blurry) I plugged them into the equation again and got 1-3/1-0 which equals -2.

Just always remember y2-y1/x2-x1=m is the equation for slope.

(m is the variable for slope)

Answer: 38 is not a perfect square.

square root of 38 is 6.164

Step-by-step explanation:

it is between 6 and 7

Answer:

6 and 7

Step-by-step explanation:

Choose the closest perfect squares either side of 38, that is

36 < 38 < 49 , then

[tex]\sqrt{36}[/tex] < [tex]\sqrt{38}[/tex] < [tex]\sqrt{49}[/tex] , that is

6 < [tex]\sqrt{38}[/tex] < 7

the answer is  2 13/5 you cant reduce it its not a proper equation

Answer:

4 1/6

Step-by-step explanation:

have an amazing day!

Answer: 2/3

Step-by-step explanation:

Number of red cubes = 2

Number of green cubes = 1

Total cubes in the bag = 3

The question relates to a probability with replacement. The probability of getting two reds will be the probability of picking red the first time multiplied by the probability of picking red the second time. This will be:

= 2/3 × 2/3

= 2/3

Answer:

8 boxes

Step-by-step explanation:

Divide 175 by 24 since you have 175 avocados and 24 can be put in each box. This gives you 7.29166666667. You have to round up to get 8.

Answer:

8 boxes would be needed

Step-by-step explanation:

175/24 = 7 with a remainder of 7 and you cannot just leave out those 7 avocados, they will be lonely so therefor you will need another box and 7+1=8

Answer:

y = -3x +11

Step-by-step explanation:

notice how on the y column the values go down by three, meaning that the slope is -3

to find the y-intercept, look at the x column and find 0 and its corresponding y value

Answer:

(x-rooot1)(x-root2)

Step-by-step explanation:

a quadratic ax²+bx+c=0 can be factor as those 2 pharanthesis

(x-rooot1) (x-root2)=0

and you can find the roots by making each parenthesis equal to 0 because of the zero product rule

x-root1 = 0, x=root1

x-root2 =0, x=root2

Answer:

204 R45

Step-by-step explanation:

Answer: The answer will be 205 R2

Step-by-step explanation:

I know this because the steps to dividing are:

D - Divide

M - Multiply

S - Subtract

B - base(total)

If you do all of those steps then you'll get 205 R2

R = remainder(left overs)

So, the answer will be 205 R2

Trigonometric Ratios

The ratios of the sides of a right triangle are called trigonometric ratios. There are six trigonometric ratios, sine, cosine, tangent, cosecant, secant, and cotangent.

The longest side of the triangle is called the hypotenuse and the other two sides are the legs.

Selecting any of the acute angles as a reference, it has an adjacent side and an opposite side. The trigonometric ratios are defined upon those sides.

The tangent ratio is defined as:

[tex]\displaystyle \tan\theta=\frac{\text{opposite leg}}{\text{adjacent leg}}[/tex]

The cotangent ratio is defined as:

[tex]\displaystyle \cot\theta=\frac{\text{adjacent leg}}{\text{opposite leg}}[/tex]

As shown above, the tangent and the cotangent are the ratios of the two legs in any possible order.

If the triangle has angles of 30°, 60°, and 90°, then we can take one of the acute angles and find the tangent and cotangent to know the required ratios:

Let's take for example the 30° angle:

[tex]\displaystyle \text{ratio of legs: }\tan 30^\circ=\frac{\sqrt{3}}{3}[/tex]

[tex]\displaystyle \text{ratio of legs: }\cot 30^\circ=\sqrt{3}[/tex]

Thus the possible ratios from the list are:

[tex]\sqrt{3}:3\\1:\sqrt{3}[/tex]

The reciprocals of those ratios are also applicable

Answer:

y = -24

General Formulas and Concepts:

Pre-Alg

Step-by-step explanation:

Step 1: Define

y = -4x² - 8

x = 2

Step 2: Solve

Answer:

Given, input (x) is 2,

[tex]y = -4x^2 - 8\\y = -4(2)^2 - 8\\y = -4(4) - 8\\y = -16 - 8\\y = -24[/tex]

Output (y) is 24
