What is 3/7 +1/5 and how would I get it<br>

Aleks04 [339]

Answer:

22/35

Step-by-step explanation:

3/7 + 1/5

First, find a common denominator.

7*5=35 multiply the numerator by 5 too: 3*5=15

5*7=35 multiply the numerator by 7 too: 1*7=7

15/35 + 7/35

=22/35

Cannot be simplified.

It is about 350 miles from Ruidoso, New Mexico, to Abilene, Texas. Haruko has already driven 75 miles and made it to Roswell, Ne

kvv77 [185]

Answer:

55 miles per hour

Step-by-step explanation:

Given that:

Distance from Mexico to Texas 350 miles

Miles already traveled = 75 miles

Hence, miles left ;

(350 miles - 75 miles) = 275 miles

To complete 275 miles in 5 hours ;

Speed = distance / time

Speed = 275 / 5

Speed = 55 miles per hour

Graph each absolute value function. State the domain, range, and y-intercept.

Inessa05 [86]

Answer:

i. D:All real numbers

ii.R: $y\le-2$

iii. Y-int: $b=-2.5$

Step-by-step explanation:

The given function is

$y=-\frac{1}{2} |x-1|-2$

The domain of this function are the values of x that makes the function defined.

The absolute value function is defined for all real values.

The domain is all real numbers.

ii. The range refers to the values of y for which x is defined.

$y=-\frac{1}{2} |x-1|-2$

The vertex of this function is

$(1,-2)$

The function is reflected in the x-axis.

The vertex is therefore the maximum point on the graph of the function.

The range is therefore;

$y\le-2$

Or

$(-\infty,2]$

iii. To find the y-intercept, we substitute $x=0$ into the funtion.

$y=-\frac{1}{2} |0-1|-2$

$y=-\frac{1}{2} (1)-2$

$y=-2.5$

The y-intercept is $b=-2.5$

The graph is shown in the attachment.

Help me please answer this question

vichka [17]

Answer:

y = 7x + 12

Step-by-step explanation:

Slope (m) = 7

Line is passing through the point (0, 12)

y-intercept (b) = 12

Equation of line in slope-intercept form is given as:

$y = mx + b \\ \\ y = 7x + 12$
