Answer:

SSS

Step-by-step explanation:

because the triagles are pretty much the same the one on the left is half of the one on the right

I got similar SAS on mine

Answer:

135 points

Step-by-step explanation:

We can solve this easily, 30x4=120+15=135

So, after shopping 30 times you would have 120 points plus the 15 you got when making the account, in total 135 points.

Answer:

Step-by-step explanation:

h(t)=30000-2000t

A) h(5)=30000-2000(5)=20000ft

B) h(8)=30000-2000(8)=14000ft

C) h(12)=30000-2000(12)=6000ft

D) 30000-2000t=0

Answer:

Sure Amaya  , the grouping is the parenthesis, right?

Step-by-step explanation:

so  just add up.. the things outside of the parenthesis

-  [tex]4^{2}[/tex] * 4

so exponents come first in the order of what to do... right?

[tex]4^{2}[/tex] =16    okay , got that part, the next part is

16 * 4 = 64   okay got that part,  now

- 64   is what is subtracted from the grouping   , got it?

Answer:

26 degrees.

Step-by-step explanation:

We are given

We are trying to find angle measure of j.

Since we are given a side opposite of our angle we are trying to find and a side adjacent to the angle we are trying to find we are going to use tan ratio.

[tex] \tan(x) = \frac{opp}{adj} [/tex]

[tex] \tan(x) = \frac{46}{93} [/tex]

since we are trying to find the angle measure apply inverse trig function

[tex] \tan {}^{ - 1} ( \frac{opp}{adj} ) [/tex]

Plug 46 for opp and 93 for adj.

[tex] \tan {}^{ - 1} ( \frac{46}{93} ) [/tex]

which is about 26 degrees.

Answer:

-12

Step-by-step explanation:

(-5)-(7) can easily be called -5-7 when all the brackets are taken away

-5-7= -12

Answer:

You can use the additive inverse to solve for x

Step-by-step explanation:

The additive inverse acquits you to change two things: the negative sign and -7

Therefore, after implementing the additive inverse, here's your expression: -5 + -7. Remeber, the rule for adding negative rational numbers: the sum of 2 negative numbers will be negative. Therefore, simply add 7 + 5 to get 12. Remebering out rule of adding negative rational numbers, you should receive -12 as your answer.

Answer:

x - 15 = - 20

Step-by-step explanation:

x - 15 = - 20

Add 15 to each side:

x - 15 + 15 = - 20 + 15

x = - 5

Answer:

[tex]\Huge\boxed{74}[/tex]

Step-by-step explanation:

Hello There!

First things first, we need to find the value of x

If you didn't know the measures of supplementary angles add up to equal 180 so we can use this equation to solve for x

180 = 2x + 3x - 5

step 1 combine like terms

2x + 3x = 5x

now we have

180 = 5x - 5 step 2 add 5 to each side

-5 + 5 cancels out

180 + 5 = 185

now we have 185 = 5x

step 3 divide each side by 5

5x/5=x

185/5=37

we're left with x = 37

Now we want to plug in 37 into x for angle A

angle a = 2(37)

2*37=74

so we can conclude that angle A = 74

Answer:

Let's verify is the corresponding sides have same ratio:

Ratios:

The ratios are same, so the triangles are similar

The scale factor (ΔABC to ΔXYZ) is 2/7 (or ΔXYZ to ΔABC is 7/2 = 3.5)

Answer:

-1.25

Step-by-step explanation:

a=15

b=-5

If you plug the values into the equation you get

-5^2/15+5

-25/20

If you simplify that you will get:

-4/5

Or:

-1.25

Answer:

Answer = -13 or 12

Step-by-step explanation:

let the two numbers be y and y+1

y(y+1)=156

y2 + y -156=0

y2 -12y+13y-156

y(y-12) +13(y-12)

(y+13) (y-12)

y+13=0

y= -13

y-12=0

y=12

Answer:

-3x+3=5x+19

5x+3x=3-19

8x=-16

x=-2

Hope this helps <3

Answer:

x = -2

Step-by-step explanation:

we know,

y is common in both

so ,

-3x + 3 = 5x + 19

-3x +3-19=5x

-3x - 16 = 5x

-3x -5x = 16

-8x = 16

x = 16 / -8

x= -16/8

x= -2

also if you put value of x = -2 in both the expression you will get y = 9

Answer: C

Step-by-step explanation:

Answer:

a) )12,6)

b) (12,2)

c) (4,-7)

d) (9,-7)

Step-by-step explanation:

a) Dilation

When we dilate, we multiply the given scale factor by each of the coordinates

We have this as follows;

(20 * 3/5, 10 * 3/5) = (12, 6)

2. Here, we will add 5 to the x-axis value and subtract 6 from the y-axis value

We have this as;

(7+ 5, 8-6) = (12,2)

3. By reflecting across the x-axis

we have (x,y) changing to (x,-y)

so we have ;

(4,7) becomes (4,-7)

4. Rotation by 270 degrees (7,9)

If clockwise;

(x,y) becomes (y,-x)

so we have

(7,9) becoming (9,-7)

Answer:

x = 70

Step-by-step explanation:

The total sum of all of the angles in a parallelogram is equal to 360 degrees. Opposite angles are also congreuent meaning that angle ADC and angle ABC are equal. Adding the sum of the two angles gives you 220. Subtract 220 form 360 and you get 140 which is equal to the sum of angles BCD and BAD. Angles BCD and BAD and the sam so dividing 140 by 2 would give you the angle measure of x.
