ANSWER:-45 - 5 = -50

EXPLANATION:

When we subtract we move left down the number line and when we add we move right up the number line

..., -50 , -49, -48, -47, -46, -45 , ... , 0, 1, 2, 3, 4, 5, ...

We are at -45 on the number line

..., -50 , -49, -48, -47, -46, -45 , ... , 0, 1, 2, 3, 4, 5, ...

We want to subtract 5 so we move 5 numbers to the left

..., -50 , -49, -48, -47, -46, -45 , ... , 0, 1, 2, 3, 4, 5, ...

This puts us at -50 therefore -45 - 5 = -50

If m<1=6x+50 and m<2=4x+40 find x

dolphi86 [110]

Angle 1 and 2 are supplementary angles and need to equal 180 degrees

so angle 1 + angle 2 = 180:

6x+50 + 4x+40 = 180

combine like terms:

10x + 90 = 180

subtract 90 from each side:

10x = 90

divide both sides by 10

x = 9

Howie wants to get a car loan with 4% simple interest rate. If the car costs $25,000, how much would Howie need to pay back at t

likoan [24]

The amount Howie will pay back at the end of one year is $26000.00

The given parameters are:

$P =25000$ -- the principal amount

$R = 4\%$ -- the interest rate

$T=1$ --- the duration

The amount to pay back in this duration is then calculated using:

$A = P(1 + RT)$

So, we have:

$A = 25000(1 + 4\% \times 1)$

$A = 25000(1 + 4\% )$

Express percentage as decimal

$A = 25000(1 + 0.04)$

$A = 25000(1 .04)\\$

Multiply

$A = 26000$

Hence, the amount to pay back is $26000.00

Which line is parallel to y= -52 + 6 and passes through (4, -2)?

Alexxandr [17]

Answer:

\[y=-5x+18\]

Step-by-step explanation:

Given that the line is parallel to \[y = -5x + 6\]

Hence the slope of the line is given by -5

Hence the equation of the required line can be represented by \[y = -5x + c\]

This line passes through (4,-2). Substituting:

\[-2 = -5 * 4 + c\]

=> \[-2 = -20 + c\]

=> c = 20-2 = 18

So the required equation of the line is given by : \[y = -5x + 18\]

From the given options, option 3 is the correct one.

Sketch the graph of y = (x + 3)2 – 4 and identify the axis of symmetry.

Sloan [31]

Answer: Thought I’d return the favor and help u with this question! But anyways, the axis of symmetry is at x = -3.

Explanatio: This can be found by looking at the basic form of vertex form:

y = (x - h)^2 + k

In this basic form the vertex is (h, k). By looking at what is plugged into the equation, it is clear that h = -3 and k = -4. This means the vertex is at (-3, -4).

It is a fact that the axis of symmetry is a vertical line of x = (vertex value of x). So we can determine that the axis of symmetry is at x = -3

i hope this helps u
