A. 90°
B. 180°
C. 80°
D. 100

Answers

Answer:

c 80

Step-by-step explanation:

by the process of elimination you can already tell that it's not 90° futhetmore 180° and 100° are way too much, you can guess these answers based on the size of it though to confirm it you should use the proper math equations, Don't forget that the angles should add up to 180 degrees meaning since there is 100° in the opposite side the answer is 80.

Answer:

I believe the answer is C.

Step-by-step explanation:

Same side interior angles tend to add up to 180 degrees, so I think you subtract 100 from 180. You get 80 degrees.

Subtract −5x^2 −9x+8 from -6x^2+5

Answers

Answer:

-(x^2 - 9 x + 3)

Step-by-step explanation:

Simplify the following:

-(-5 x^2 - 9 x + 8) - 6 x^2 + 5

Factor -1 out of -5 x^2 - 9 x + 8:

--(5 x^2 + 9 x - 8) - 6 x^2 + 5

(-1)^2 = 1:

5 x^2 + 9 x - 8 - 6 x^2 + 5

Grouping like terms, 5 x^2 - 6 x^2 + 9 x - 8 + 5 = (-6 x^2 + 5 x^2) + 9 x + (5 - 8):

(-6 x^2 + 5 x^2) + 9 x + (5 - 8)

5 x^2 - 6 x^2 = -x^2:

-x^2 + 9 x + (5 - 8)

5 - 8 = -3:

-x^2 + 9 x + -3

Factor -1 out of -x^2 + 9 x - 3:

Answer:  -(x^2 - 9 x + 3)

6х + 17 = -7
justify each step

Answers

Answer:

x = -4

Step-by-step explanation:

Subtract 17 on both sides to get 6x = -24 then divide 6 to both sides to get your answer of x = -4

First, you need to get 6x by itself. So you would subtract 17 from both sides. After that you should have 6x= -24.Then you need to get x by itself. You divide 6 from both sides. The answer is x= -4.

Solve for u in terms of s, t, v, and w.
vt= -swu

u=

Answers

Answer. u=vt/-sw
In order to solve for u, we must isolate it.
v•t=-s•w•u. To isolate the variable, u, all other variables must be moved to the other side of the equation. So, divide -sw by vt and you get u= vt/-sw. Hope this helps, let me know if it’s correct so others can use it :)
Good luck.

The value of the expression given in terms of u is -vt / sw

What is an expression?

Expressions in math are mathematical statements that have a minimum of two terms containing numbers or variables, or both, connected by an operator in between.

Given that, an expression, vt = -swu, we are asked to find the expression in terms of u,

vt = -swu

u = -vt / sw

Hence, the value of the expression given in terms of u is -vt / sw

How is solving literal equations like solving equations in one variable

Answers

Answer:

When given a literal equation, you will often be asked to solve the equation for a

given variable. The goal is to isolate that given variable. The process is the same

process that you use to solve linear equations; the only difference is that you will

be working with a lot more letters, and you may not be able to simplify as much as

you can with linear equations. This packet will hopefully show you the process in a

simple manner so that you will be able to solve literal equations yourself. See

examples before for the method to solving literal equations for a given variable:

Answer:

Step-by-step explanation:

To solve a literal equation means to rewrite the equation so a different variable stands alone on one side of the equals sign. We have to be told for which variable we want to solve.

Linear equations in one variable may take the form a x + b = 0 \displaystyle ax+b=0 ax+b=0 and are solved using basic algebraic operations. We begin by classifying linear equations in one variable as one of three types: identity, conditional, or inconsistent. An identity equation is true for all values of the variable.

Answers

DONT LISTEN TO THEM. The slope is 6.
It’s y2-y1/x2-x1
EXPLANATION
Therefore
x1=3
y1=1
x2=1
y2= -11
So -11 -1= -12 and 1 - 3 = -2 then you divide it
-12/-2 two negatives makes a positive so it’s 6

In the table shown, the ratio of miles biked to hours biked is constant.

Answers

Answer:

B

Step-by-step explanation:

You can see it would come out to be one with 44/4 so if you made it m/7 it would have to come out with a one so it would be 77.

The proportion 44/4=m/7 can be used to determine the value of m.

What is Ratio?

A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0.

The  ratio of miles biked to hours biked is constant.

The given table is

Miles biked    11        44     m        132    165

Hours biked    1         4       7         12      h

We have to find the value of m.

m is the number of miles biked in 7 hr.

By using the proportion we can find m.

44/4=m/7

11=m/7

Apply cross multiplication

m=77

Hence, the proportion 44/4=m/7 can be used to determine the value of m.
