You do multiblecation before addition so you put it in parenthesis
what does this q equal
Answer:
30 degrees
Step-by-step explanation:
Since all triangles' angles add up to 180 degrees, you can add the sum of the angles you already know and subtract it from 180.
126+24=150
180-150=30
so angle Q = 30 degrees

f(x) = 5x + 25 - 1
8(x) - - 2x-3
Answer:
f(x)=5x+25-1
8(x)- -2x-3
=30-1
=8x+6x
=29+14x
43x
The point of intersection of the two functions is (3, 27).
The system of equations is:
f(x) = 5x + 25 - 1 = 5x + 24
g(x) = 2x - 3
To solve this system, we can use the elimination method. We can eliminate the x-term by adding the two equations together.
f(x) + g(x) = 5x + 24 + 2x - 3 = 7x + 21
Solving for x, we get:
x = 21/7 = 3
Now that we know the value of x, we can plug it back into either equation to find the value of y. Let's use the equation for f(x).
f(x) = 5x + 24
f(3) = 5(3) + 24 = 27
Therefore, the point of intersection of the two functions is (3, 27).
To the nearest tenth, the point of intersection is (3.0, 27.0).

A car covers the distance between two cities in 6 hours. A van covers the same distance in 5.5 hours by travelling 4 km/h faster than the car. What is the distance between the two cities? Find the speed of the car and the van.
Step-by-step explanation:
[tex]\large\underline{\sf{Solution-}}[/tex]
Given that,
A car covers the distance between two cities in 6 hours.
A van covers the same distance in 5.5 hours.
The speed of the van is 4 km per hour faster than the speed of car.
Let assume that
Speed of the car be x km per hour
So,
Speed of van is x + 4 km per hour.
Let further assume that
Distance between two cities be y km.
We know, Distance covered = Speed × Time.
➢ Now, Distance (y) covered by car at the speed of x km per hour in 6 hours is
[tex]\rm :\longmapsto\:\boxed{\tt{ y = 6x}} - - - - (1)[/tex]
➢ Also, Distance (y) covered by van at the speed of x + 4 km per hour in 5.5 hours is
[tex]\rm :\longmapsto\:\boxed{\tt{ y = 5.5(x + 4)}} - - - - (2)[/tex]
So, from equation (1) and (2), we have
[tex]\rm :\longmapsto\:6x = 5.5(x + 4)[/tex]
[tex]\rm :\longmapsto\:6x = 5.5x + 22[/tex]
[tex]\rm :\longmapsto\:6x - 5.5x = 22[/tex]
[tex]\rm :\longmapsto\:0.5x = 22[/tex]
[tex]\rm :\longmapsto\:\dfrac{5}{10} \times x = 22[/tex]
[tex]\rm :\longmapsto\:\dfrac{1}{2} \times x = 22[/tex]
[tex]\bf\implies \:x = 44[/tex]
On substituting the value of x, in equation (1), we have
[tex]\rm :\longmapsto\:y = 6 \times 44[/tex]
[tex]\bf\implies \:y = 264[/tex]
So,
[tex]\begin{gathered}\begin{gathered}\bf\: \rm :\longmapsto\:\begin{cases} &\sf{Distance \: between \: cities = 264 \: km} \\ \\ &\sf{Speed \: of \: car \: = \: 44 \: km \: per \: hour}\\ \\ &\sf{Speed \: of \: van \: = \: 48 \: km \: per \: hour} \end{cases}\end{gathered}\end{gathered}[/tex]
Find the measure of each missing angle
I’ll give BRAINLEST!!
Answer:
angle 4 = 115°[vertically opposite angles]
angle 2+ angle 4=180°[linear pair]
angle 2+ 115 = 180°
angle 2 = 180°-115°
angle 2=65°
angle1+angle2+80°=180°[sum of all angles is 180°]
angle1+65°+80°=180°
angle 1 + 140° = 180°
angle 1=180°-140°
angle1 =40°
angle2= angle5[vertically opposite angles]
angle7+angle5+61°+90°=360°[sum of all angles of quadrilateral is 360°]
angle7+ 65°+ 61° +90°=360°
angle7+ 211°=360°
angle7=360°-211°
angle7=149°
angle7+angle6=180°[linear equation]
149°+angle6=180°
angle6=180°-149°
angle6=31°
angle4+angle6+angle3= 180°[by sum of all angles is 180°]
115°+31+angle3=180°
146°+angle3=180°
angle3=180°-149°

If Michael made 12 shots out of 18 what is the percentage of shots made by him?
Answer:
At least 66%
Step-by-step explanation:
65% of 18 is 11.7
67% of 18 is 12.06
Therefore, at least 66% of the shots where made by Michael.
Step-by-step explanation:
100% = 18
x% = 12
x% = 100% / 100 × x
so,
18/100 × x = 12
18x = 1200
x = 1200/18 = 200/3 ≈ 66.66666...
so, he made about 67% of the shots.

Q. Which of these represents stope-intercept form of a linear equation?
answer choices
A)Ax+By=c
B)y-yı = m-x)
C)y=kx
D)y=mx + b
Answer:
D
Step-by-step explanation:
this is so easy just plug the question in
Answer:
D.y= mx + b
Step-by-step explanation:
Slope-intercept is a specific form of linear equations. It has the following general structure
y= mx + b
Here, m can be any two real numbers. For example, these are linear equations in slope-intercept form:
y=2x+1
y=-3x+2.7y
y=10-100x
On the other hand, these linear equations are not in slope-intercept form:
2x+3y=5
y-3=2(x-1)y−3=2(x−1)
x=4y−7
Slope-intercept is the most prominent form of linear equations
I NEED SOME HELP! Please? Lines a and b lie in the standard (x,y) coordinate plane. An equation for line a is y = 0.15x + 5000. The slope of line b is 0.2 greater than the slope of line a. What is the slope of line b?
0.35
0.05
0.015

500
In the standard (x,y) coordinate plane, which of the following lines are perpendicular to the line 2y = 3x + 1?
y = - 2/3x + 3
y = -3/2x - 1
y = 2/3x - 1
y = 3/2x + 2
y = 2/3x + 1
a. Just add 0.2 to 0.15 in equation a. y = mx + b shows that m is the slope. Answer would be 0.35.
b. 2y = 3x + 1
y = 3x/2 + 1/2
Perpendicular = negative reciprocal of original function's slope.
3/2 -> -2/3x.
Only the first one fulfills the equation, thus:
-2/3x + 3.
(1) The slope of line b is 0.35. The correct option is A.
(2) The equation perpendicular to the line y = - 2/3x + 3. The correct option is A.
What is an equation of the line?An equation of the line is defined as a linear equation having a degree of one. The equation of the line contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.
The general form of the equation of the line:-
y = mx + c
m = slope
c = y-intercept
Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )
(1) An equation for line a is y = 0.15x + 5000. The slope of line b is 0.2 greater than the slope of the line.
The slope of line b,
b = 0.2 + a
b = 0.2 + 0.15
b = 0.35
(2) The equation of the line perpendicular to the line 2y = 3x + 1 is calculated as:-
The slope of the line perpendicular to the other line is the opposite reciprocal. The equation will be,
y = -2/3x + 3

A taxi charges a flat rate of $1.75, plus an additional $0.65 per mile. If Erica has at most $10 to spend on the cab ride, how far could she travel? Write an inequality expression that represents the situation and solve! Explain your reasoning! You can copy/paste the needed symbols as needed: ≥ ≤
Answer:
The inequality expression would be 1.75+0.65x ≥10
She would be able to ride ~12.7 miles or just 12 miles rounding down.
Step-by-step explanation:
Following mx+b, the m value would be 0.65 because it is added per mile.
The 1.75 would be the b value because it is the starting value.
So the equation would look like 1.75+0.65x. To know if the 10 value would be less than or more than, we have to know if 10 is the limit value or starting value. Because 10 is our limit value, we will use greater than or equal to.
To know how many miles Erica could travel, we would have to subtract 1.75
from 10. We would get 8.25. We would then divide 8.25 by 0.65. so the number of miles she can travel is ~12.7 miles or just 12 miles rounding down.
