HELPP. Write the following as an algebraic expression. The sum of a and a quarter of b.

Fynjy0 [20]

Answer: $a + \frac{1}{4}b$

This is the same as $a + \frac{b}{4}$

All we're doing is adding 'a' and $\frac{1}{4}b$ since the term "sum" is the result of adding two or more numbers.

One quarter of a number is the same as dividing by 4.

Example: one quarter of 28 = $\frac{1}{4}*28 = \frac{28}{4} = 7$

Find the equation of the line with slope = 6 and passing through (-4,-22). Write your equation in the form

dusya [7]

Answer:

y = 6x +2

Step-by-step explanation:

It is useful to start with the point-slope form of the equation for a line when you are given a point and a slope.

y -k = m(x -h) . . . . line with slope m through point (h, k)

y -(-22) = 6(x -(-4))

y +22 = 6x +24 . . . simplify

y = 6x +2 . . . . . . subtract 22

Write a proportion for each of the following equations and perform all changes: a 2·9=3·6

just olya [345]

$\boxed{\frac{2}{3}=\frac{6}{9}}$

Step-by-step explanation:

The equation we are given is the following:

$2\cdotp9=3\cdotp6$

A proportion is a relationship between two ratios. This tells us that two ratios are equal. That is, suppose you have two ratios:

$(1) \ \frac{a}{b} \\ \\ (2) \ \frac{c}{d}$

Then, we can write a proportion as follows:

$\frac{a}{b}=\frac{c}{d}$

For:

$2\cdotp9=3\cdotp6$

If you divide both sides by (3)(9):

$\frac{1}{3\cdotp9}(2\cdotp9)=\frac{1}{3\cdotp9}(3\cdotp6) \\ \\ \boxed{\frac{2}{3}=\frac{6}{9}}$

egoroff_w [7]

Answer: 281.1 degree

Step-by-step explanation:

Given that a jogger leaves his house runs 15 km on a straight track in a North westerly direction to a lake. The lake is 2.9 km north of the joggers house.

Using pythagorean theorem to find the third side, which is 14.72

The angle at the lake side will be achieved by using sine rule.
