Answer:
a = 4
Step-by-step explanation:
2a + 7 = 15
- 7 - 7
2a = 8
/2 /2
a = 4
Hope this helps!
Answer:
a=4
Step-by-step explanation:
We need to find a way to get (a) alone on one side.
first, we will subtract 7 from 15 to get 8.
Next, We will divide 8 by 2. to get 4
your work should look like this.
2a+7=15
2a=15-7
2a=8
a=8/2
a=4

Answer:
The functions have the same y-intercept.
OPTION C is correct.
Step-by-step explanation:
DEFINITIONS AND FORMULAS
The equation of a linear graph is given to be:
[tex]y=mx+b[/tex]
Where m is the slope of the graph and b is the y-intercept.
To calculate the slope given a table, we can use the formula:
[tex]m=\frac{y^{2}-y^{1} }{{}x^2 -x^1}[/tex]
SOLUTION
Function 1: The equation of the graph is given to be
[tex]p=-\frac{3}{2}r-5[/tex]
Therefore, the y-intercept of the graph is given to be:
[tex]b=-5[/tex]
Function 2: Recall that the y-intercept of a graph is the y-value when x = 0.
On checking the graph, we can see that when r = 0, p = -5.
Therefore, the y-intercept is:
[tex]b=-5[/tex]
ANSWER
The functions have the same y-intercept.
OPTION C is correct.
this took me awhile but the answer is function 1

Jordan says that the shortest side
of any isosceles triangle has to be
at least 6 units, but Tierra says
there is no minimum length for the
shortest side of an isosceles
triangle. Who is right? Why?
Answer: I'm pretty sure Tierra is right because an isosceles triangle does not have a minimum side length. It's just the shortest length has to be equal to the other shortest length.
Step-by-step explanation: properties of an isosceles triangle.

Answer:
106.62729675 ft

write the equation if this line below
Answer:
Step-by-step explanation:
The first step to finding the equation of this line we must find two points that are on this line.
Two points on the lines are (0,3) and (1,0).
Now we must find the slope:
[tex]slope = \frac{y2-y1}{x2-x1} = \frac{3 - 0}{0-1} =-3[/tex]
Now after finding the slope which is -3, now let us put it into the point-slope form using the point (0,3) which is also on the line. You could also use (1,0) in this case, but I am using (0,3).
[tex]y-3 = -3(x-0)\\y=-3x +3[/tex]
Thus the equation is [tex]y=-3x +3[/tex]
Hope that helps!
people keep putting nonsense answers on my questionsomeone plsss help me. the answer is y=2x+16 and y=-2x-20
Answer:
[tex]y=(x+8)(x+10)=x^2 + 18x + 80[/tex]
[tex]\frac{dy}{dx} = 2x + 18[/tex]
[tex]y=0[/tex] when [tex]x=-8[/tex] and [tex]x=-10[/tex]
so the tangent slopes are [tex]\frac{dy}{dx} = 2[/tex] and -2 at those x.
The lines are y = 2x + b and y = -2x + c.
We need to find b and c.
The first line must go through (-8,0) and the second one through (-10,0).
For the first line: 0 = 2*(-8) + b and b = 16.
For the second line: 0 = -2*(-10) + c and c = -20.

Write the following as an inequality.
x is greater than or equal to -2 and less than or equal to 5
Use x only once in your inequality.
Answer:
-2 ≤ x ≤ 5
Step-by-step explanation:
x is greater than or equal to -2 and less than or equal to 5
⇒ x ≥ -2 and x ≤ 5
⇒ -2 ≤ x ≤ 5
From eq(1) and (2)
Combine them
[tex]\\ \rm\hookrightarrow -2\leqslant x\leqslant 5[/tex]

Answer:
[tex]\frac{41}{11}.[/tex]
Step-by-step explanation:
1) to make up the equation of the given line:
[tex]\frac{x-X_R}{X_S-X_R} =\frac{y-Y_R}{Y_S-Y_R}; \ => \frac{x+5}{1+5} =\frac{y+6}{5+6}; \ => \frac{x+5}{6} =\frac{y+6}{11}.[/tex]
2) to substitute y=10 into the equation of the given line, then to calculate the value of 'x':
[tex]\frac{x+5}{6} =\frac{10+6}{11}; \ => \ x=\frac{96}{11}-5=\frac{41}{11}.[/tex]
Equation of ST :-

Answer:
100
Step-by-step explanation:
Write in an equation:
4=4%x, then divide 4% from both sides, and then you get 100.
Answer:
Step-by-step explanation:
We have, 4% × x = 4
or,

100
× x = 4
Multiplying both sides by 100 and dividing both sides by 4,
we have x = 4 ×

what is the value of x if the volume is 24 ft cubed?
PLS ANSWER FAST IM IN THE MIDDLE OF A TEST
Answer:
8 since cubed is x3 24 divided by 3 is 8
Answer:
x= 6
Step-by-step explanation:
The formula for volume of a rectangle is V= Length x Width x Height.
Therefore: 24 = 3 * 2 * x
24= 6 * ?
24 = 6 * 4
The value of x is 6
A utility pole makes a 90° angle with the ground. A cable wire

B.)90°
C.)70°
D.)20°
Answer:
C- ) 70 degrees
Step-by-step explanation:
180 is the degree of half circle you already have the first number 110 now you need to find out which number gets you to 180 and the only one that works it 70
110+70

what do you add to 35 over 8 to make 6
Answer:
You would add [tex]\frac{13}{8}[/tex] or 13/8 (fraction)
Step-by-step explanation:
First we make an equation with the following evidence:
We know 35 over 8 is [tex]\frac{35}{8}[/tex]
And we know were trying to get 6
The unknown is the "add" which gives us X
Equation: x + [tex]\frac{35}{8}[/tex] = 6
When we solve the equation we get x = 13/8
How do we solve it?
Subtract 35/8 on both sides:
x + 35/8 -35/8 = 6 - 38/8
And leaves us with x = 6

C(x) = (12,000x - 0.02x^3) - (3000x - 0.002x^3)
Write a simplified expression for C(x).
A. C(x) = -0.022x^3 + 9000x
B. C(x) = -0.018x^3 + 9000x
C. C(x) = -0.022x^3 + 15,000x
Answer:
B
Step-by-step explanation:
C(x) = (12,000x - 0.02x^3) - (3000x - 0.002x^3)
C(x) = 12,000x - 0.02x^3 - 3000)x + 0.002x^3
C(x) = (12,000 - 3,000)x + (-0.02 - 0.002)x^3
= 9000x - 0.018x^3
Simplify the equation.
