Solve for x I need help on questions 5 & 6

Effectus [21]

Answer:

#5 x=8, #6 x=5

Step-by-step explanation:

Theyre vertical so for number 5 you would have the equation

5x+15=55

-15 -15 from both sides

5x=40

divide by 5 from both sides and you get

x=8

Same thing vertical so you would have

16x+7=87

-7 -7 from both sides

16x=80

divide by 16 from both sides

x=5

Solve the following equation. log Subscript 2 Baseline (3 x plus 7 )equals 5 The solution set is StartSet nothing EndSet . (Sim

tigry1 [53]

Answer: $x=\dfrac{25}{3}$

Step-by-step explanation:

The given equation : $\log_2(3x+7)=5$

Using logarithmic property : $\log_a N=M\to N=a^M$

The given equation will be equivalent to $(3x+7)=2^5$

$\Rightarrow\ 3x+7=32$

Subtract 7 from both sides , we get

$3x=25$

Divide both sides by 3 , we get

$x=\dfrac{25}{3}$

Hence, the solution is $x=\dfrac{25}{3}$

Y= -1/2x-3 <br> Plot the x- and y-intercepts to graph the equation.

viva [34]

Answer:

Graph is attached below

Step-by-step explanation:

Intercepts are values of x and y at which the graph of the function intersects coordinate axis.

Given equation,

$y=-\frac{1}{2}x - 3$

For x-intercept,

y = 0,

$\implies 0 =-\frac{1}{2}x - 3$

$3 =-\frac{1}{2}x$

$\implies x =-6$

Thus, x-intercept is at (-6, 0)

For y-intercept,

x = 0,

$\implies y =-\frac{1}{2}(0) - 3=-3$

Thus, y-intercept is at (0, -3)

Now, join these two points to show the line in coordinate plane.

- 3x + y = 6<br> what is the slope-intercept

tatiyna

Answer:

Slope: 3 Y-intercept: 6

Step-by-step explanation:

You want to put this equation into y=mx+b form so it's easier to tell.

Add 3x on both sides.

y = 3x + 6

The slope is always the coefficient (number) in front of the x in the y = mx + b form. 6 is the y-intercept (reason: the y-intercept is when x=0, and when you substitute 0 for x in this, you get y=6).
