3x - 7 (4+2x) = -x +2

Answer:

Step-by-step explanation:

An investment banker received a bonus and invested that money in two investments. He put a certain sum

of money in the first investment that returned 7% interest after one year. In the second investment he

Invested four times that of the first investment and got a 12% interest return after one year. If the total

interest from his investments after one year was $8,525.00, find the amount invested at each interest rate.

Based on the inscribed angle theorem, the measure of angle BED in the diagram given is: 57°.

The inscribed angle theorem states the measure of the inscribed angles subtended by the same arc are the same.

∠BCD and ∠BED are subtended by the same arc BD.

Therefore, based on the inscribed angle theorem, we have:

m∠BCD = m∠BED = 57°.

m∠BED = 57°

Answer:

(5.5, 12.5) OR (11/2, 25/2)

I would put in the decimal value as the answer, but of you like then you can add the fraction as an answer.

Step-by-step explanation:

We are given the endpoints (-4, 15) and (22, 3) to find the midpoint. In order to find the midpoint, we will use its formula.

Midpoint formula :- (x1 + x2 / 2, y1 + y2 / 2)

(x1 + x2 / 2, y1 + y2 / 2)

(-4 + 15 / 2, 22 + 3 / 2)

(11 / 2, 25 / 2) ---> (5.5, 12.5) Midpoint

x = - 3

Step-by-step explanation:

The axis of symmetry is a vertical line passing through the vertex of the parabola with equation

x = c

where c is the value of the x- coordinates the line passes through

The line passes through (- 3, - 6), (- 3, 4 ) with x- coordinates - 3

Then equation of axis of symmetry is x = - 3

Answer:

Joe hit 11 balls       Roy hit 41

Step-by-step explanation

Joe = J

Roy = 4J-3 (4times Joe  less 3)

J+ 4J-3 = 52

5J -3 = 52

Add 3 on both sides  

5J = 55

Divide both sides by 5

J= 11

Joe = 11

11X4 = 44

44-3 = 41

Roy 41

11+41 = 52

Step-by-step explanation:

The formula of finding the surface is length * width * height or LxWxH.

Since everything is 6 you just multiply 6*6*6 which gives you 36*6 which gets you 216. You don't need the top 6 just to find the surface she will paint.

Answer:

False

Step-by-step explanation:

False, because whenever you subtract a negative number, you always end up adding because two negatives make a positive. Lets say n is 4 and m is -3, 4-(-3) is going to turn into 4+3=7.

The Awad'claims that "when m is a negative integer and n is a positive integer, n - m is always negative". which is false.

A number system is defined as a way to represent numbers on the number line using a set of symbols and approaches. These symbols, which are known as digits, are numbered 0 through 9. Based on the basic value of its digits, different types of number systems exist.

Awad claims that when m is a negative integer and n is a positive integer, n - m is always negative.

The above claim is false because subtracting a negative integer always results in an addition because two negatives equal a positive.

For example, n is 6 and m is -2; 6 -(-2) will equal 6 + 2 = 8.

Hence, the Awad'claims that "when m is a negative integer and n is a positive integer, n - m is always negative". which is false.

Answer:

C) y = 2x

Step-by-step explanation:

That's the only equation that if x = 0, y will = 0

Answer:

C

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

A

y = x + 1 ← has a y- intercept of 1

B

y = x - 1 ← has a y-intercept of - 1

C

y = 2x ← has a y- intercept of 0

D

y = 2x + 2 ← has a y- intercept of 2

Thus y = 2x passes through the origin → C

Answer:

(a) 2 degree celsius per hour

(b) 3 degree celsius per hour.

Step-by-step explanation:

From the question,

(a) Avearge rate of rise in temperature per hour(T') = Rise in temperature(T)/Time required for the rise(t).

T' = T/t.................... Euqation 1

Rise in temperature (T) = 4 degree celsius, t = 10.00 am to noon = 2 hours.

Substitute into equation 1

T' = 4/2

T' = 2 degree celsius per hour.

(b) Also,

Average rate of fall in temperature per hour (T') = Fall in temperature (T)/Time(t)

T' = T/t

Given: T = 6 degree celsius, t = 3:00 pm to 5:00 pm = 2 hours

T' = 6/2

T' = 3 degree celsius per hour
