Crosby had $300 in his checking
account. Over one week, he
withdrew $50, wrote a check for
$20, and deposited $60. What was
his account balance at the end of
the week?

Answer:

no because the lines are not parallel

Calculation:

[tex]\log ^2_3\left(\frac{1}{3}\right)=-1[/tex]

[tex]\log _3\left(\frac{1}{3}\right)[/tex]

[tex]\frac{1}{3} = 3^{-1}[/tex]

[tex]=\log _3\left(3^{-1}\right)[/tex]

[tex]=-1[/tex]

Answer:

Answer:

1a 2a

Step-by-step explanation:

n × (−2+5 ) = −8+20

n × 3 = 12

n = 4

2 + (n+6) = −1+6

n + 8 = 5

n = -3

Answer:

2/1 or 2

Step-by-step explanation:

so first, you have to count the rise/run. This line rises up 2 and runs to the right 1. To find out the rise/ run, find a place in the graphed line where it is on a plot point. For example: (40, 30). Then just see how much it rises and how much it runs.

Answer:

$133.50

Step-by-step explanation:

100%-11%=89%

89%=0.89

Step-by-step explanation:

4x -5 = 3x +11 corresponding angles

x= 16

y + 4x - 5 = 180

y + 4(16) = 185

y - 64 =185

y = 121

Answer:

-3a + 4ab

Step-by-step explanation:

-5a + 2a = -3a

-6ab + 10ab = 4ab

=−5a+−6ab+10ab+2a

=−5a+−6ab+10ab+2a

=(−6ab+10ab)+(−5a+2a)

=4ab+-3a

=4ab-3a

Let the number be multiplied be 'x'.

Therefore, according to the given conditions:

[tex] \rm\longmapsto {3}^{ - 3} \times x = 4[/tex]

We know that:

[tex] \rm\red⇛ {x}^{ - a} = \dfrac{1}{ {x}^{a} } [/tex]

Therefore:

[tex] \rm\longmapsto \dfrac{1}{ {3}^{3} } \times x = 4[/tex]

[tex] \rm\longmapsto \dfrac{x}{27 } = 4[/tex]

Multiplying both sides by 27, we get:

[tex] \rm\longmapsto27 \times \dfrac{x}{27 } = 4 \times 27[/tex]

[tex] \rm\longmapsto x = 4 \times 27[/tex]

[tex] \rm\longmapsto x = 108[/tex]

So, 108 must be multiplied to get 4.

Verification:

Substitute x = 108, we get:

[tex] \rm = {3}^{ - 3} \times 108 [/tex]

[tex] \rm = \dfrac{1}{27} \times 108 [/tex]

[tex] \rm = \dfrac{1}{27} \times 27 \times 4[/tex]

[tex] \rm =4[/tex]

Answer:

The six is bigger

Step-by-step explanation:

They both are inside the absolute value sign, meaning, the the numbers are negative, they will turn positive and if they are positive, then they will remain positive. So, in this case 4 and 6 are both positive and remain positive. And obviously 6 is greater than 4 because 6 comes after 4 in a number line.  

Answer:

Step-by-step explanation:

Perpendicular lines have negative reciprocal slopes. This means that when you multiply the slopes of the perpendicular lines, its product = -1.

Given the linear equation, y = -9x - 1, and the point, (-3, 7):

Since the slope of the given linear equation is: m1 = -9, then it means that the slope of the other line (m2) = 1/9:

m1 × m2 = -1

-9 × 1/9 = -1

Next, we need to find the y-intercept of the other line. The y-intercept is the point on the line where it crosses the y-axis, and has coordinates (0, b). It is also the value of the y-coordinate when its corresponding x-coordinate = 0.

Using the given point, (-3, 7), and the slope of the other line, m2 = 1/9:

We need to substitute these values into the slope-intercept form, y = mx + b, to solve for the y-intercept, (b):

y = mx + b

7 = 1/9(-3) + b

7 =   -1/3 + b

Add 1/3 to both sides of the equation to solve for b:

7 + 1/3  = 1/3 -1/3 + b

22/3 = b

Therefore, the y-intercept (b) = 22/3.

The linear equation of the other line is: y = 1/9x + 22/3  

Answer:

−8x^2+11x−10

Step-by-step explanation:

Answer:

-8x² + 11x - 10

Step-by-step explanation:

5(3x - 2) - 4(2x + 1)x

15x - 10 - 8x² - 4x

11x - 10 - 8x²

= -8x² + 11x - 10

Answer:

x = 30

Step-by-step explanation:

-6 + 24 = x - 24 + 24

x = 24 + 6 - 24 - 24

x = 30 - 0

 x = 30
