Answer:

[tex]y=-\frac{4}{3}x+1[/tex]

Step-by-step explanation:

Hi there!

What we need to know:

1) Determine the slope (m)

[tex]y=\frac{3}{4} x - 6[/tex]

Looking at the given equation, we can identify clearly that [tex]\frac{3}{4}[/tex] is in the place of m, making it the slope of the line. Because perpendicular lines always have slopes that are negative reciprocals, we know that the slope of the line we're solving for will be [tex]-\frac{4}{3}[/tex]. Plug this into [tex]y=mx+b[/tex]:

[tex]y=-\frac{4}{3}x+b[/tex]

2) Determine the y-intercept (b)

[tex]y=-\frac{4}{3}x+b[/tex]

Plug in the given point (-3,5)

[tex]5=-\frac{4}{3}(-3)+b\\5=4+b[/tex]

Subtract 4 from both sides

[tex]5-4=4+b-4\\1=b[/tex]

Therefore, the y-intercept is 1. Plug this back into [tex]y=-\frac{4}{3}x+b[/tex]:

[tex]y=-\frac{4}{3}x+1[/tex]

I hope this helps!

Answer:

5^6 × 5^(-2) × 5^(-7)

= 5^{6+(-2)+(-7)}

= 5^{6-2-7}

= 5^(-3)

Option c 5^-3

Answer:

x= -7

Step-by-step explanation:

x+4= -3

x= -3-4

x= -3+(-4)

x= -7

Answer:

fist multiply x and 4 by 7 then subtract 28 from -21 which gives you 7 and 7 divided by 7 equals 1

Answer:

c=-18 d=2

Step-by-step explanation:

[ 6 8 -11 15 ]-[c+2 3 -5 d-4 ]=[ 22 5 -6 17]

The equation tells that when the two matrices are subtracted we get the resultant matrix.

Each element of the first matrix corresponds to each element of the second matrix

From above

6- (c+2)= 22

6- c-2= 22

4-c= 22

-c= 22-4

-c= 18

c= -18

And

15-( d-4)= 17

15- d+4= 17

19-d= 17

-d= 17-19

-d= -2

d= 2

Answer:

D

Step-by-step explanation:

c= -18

d= 2

Answer:

16.2feet

Step-by-step explanation:

Using the SOH CAH TOA identity

Given the following

Base side = 24feet

angle of elevation = 34degrees

Required

Height of the tree (opposite)

tan theta = opposite/adjacent

tan 34 = H/24

H = 24tan34

H = 24(0.6745)

H = 16.2feet

Hence the height of the tree is 16.2feet

Answer:

171 [tex]in^2[/tex]

19.5 [tex]in^2[/tex]

Step-by-step explanation:

To find the area of a parallelogram, one uses the following formula,

[tex]A=(base)(hieght)[/tex]

Substitute in the given values, and find the area of the parallelogram.

1.

Base = 16

Hieght = 11

 [tex]Area=(base)(height)\\= (11)(16)\\=176[/tex]

2.

Base = 1.5

Hieght = 13

[tex]Area=(base)(hieght)\\=(1.5)(13)\\=19.5[/tex]

What is the question?.

Step-by-step explanation:

I didn't see any MatHS problem.

Answer:

Nathan

y = 2x + 30

Olivia

y = 4x + 15

x = 7.5

This means by the 8th week Olivia will have more saved

Step-by-step explanation:

Nathan

y = 2x + 30

Olivia

y = 4x + 15

-------------------------

substitute 4x + 15  for y in the first equation

4x + 15 = 2x + 30

Subtract 2x from both sides

2x + 15 = 30

Subtract 15 from both sides

2x = 15

Divide both sides by 2

x = 7.5

This means by the 8th week Olivia will have more saved

Answer:

Nathan: 2x+30

Olivia: 4x+15

Week 7.5

Step-by-step explanation:

They add money (x) and there was already money in the account so you need to add that.  4(7.5)+15=45, 2(7.5)+30=45. It means that the week 7.5, they will each have the same amount in their bank account. After that, olivia will have more money in her bank account, and nathan did, but after week 7.5 he will not.

Answer:

The slope is 1

Step-by-step explanation:

Slope = (y₂-y₁)/(x₂-x₁) = (2-3)/(4-5) = (-1)/(-1) = 1

Therefore, the slope of the line that passes through (5,3) and (4,2) is 1

Answer:

11 cats

Step-by-step explanation:

Given :

Jane's initial = 23

My initial = 2

Jane gives out 5 cats to me ;

Jane's new = 23 - 5 = 18

My new = 2 + 5 = 7

Number of cats Jane has than me :

Jane's new - My new

18 - 7 = 11 cats
