Answer:

(46 , -17)

Step-by-step explanation:

hello :

x + y = 29...(*)

x + 2y = 12 ...(**)

multiply (*) by -1 : -x-y=-29   ...(***)

add (**) and(***) : y=-17

put this value in (*) : x-17 =29

so : x=46

one solution : (46 , -17)

Which of the following linear equations has the steepest slope
Pani-rosa [81]

Option B: 8x+1 has the steepest slope

Step-by-step explanation:

Slope is defined as the rate of change of a line

The steepness of a slope means how close it is to being vertical

The greater value of slope means, more steepness. The value of slope can wither b positive or negative

We have to compare the slopes of all given options to find the steepest slope

As the options are in slope-intercept form, the coefficients of x will be the slope

So,

a. Slope = -4

b. Slope = 8

c. Slope = 2/3 = 0.66

d . Slope = 1/7 = 0.14

We can see that the largest value of slope in negative and positive is 8

So,

Option B: 8x+1 has the steepest slope

Keywords: Slope, steepness

How do I find the answer?
seraphim [82]

Answer:

96

Step-by-step explanation:

Formulas for area:      Parallelogram= Base * Height  

                                     Triangle= Base * Height / 2

1st triangle to the left: 8*6=48/2=24

2nd triangle to the right:

<u>1st step:   </u>6²+b²=10²

                 36-36+b²=100-36

                 √b²=√64²

                    b=8

2nd step:  6*8=48/2=24

only parallelogram:

6*8=48

Final step: 24+24+48=96

Choose the set that consists of only prime numbers.
butalik [34]
The answer is C because 2, 5, 23, and 29 are prime numbers (you can also look up a chart and highlighted numbers are prime). prime numbers is a whole number greater than 1 and cannot be formed when multiplying two smaller numbers that are whole. it must involve itself in a multiplication equation.

What is 6 to the power of 2 divided by 2 times 3 plus 4
lidiya [134]
6^{2} ÷ 2*3+4

You use the order of operations with PEMDAS

P⇒Parentheses 

E⇒Exponents

M⇒Multiplication 

D⇒Division

A⇒Addition

S⇒Subtraction

6^{2} ⇒  6*6=36

36*3=108

108 ÷ 2=54

54+4=58

Answer: 58
