fill in blanks to write the function when x=3 h(x)=-4-7, when x=3:
h(__)=__
Answer:
h(x)= -4x-7, when x=3
Answer= h(3)= -19
Step-by-step explanation:
Substitute 3 for x in the function and simplify:
h(x) = -4x – 7
h(3) = -4(3) – 7
= -12 – 7
= -19
The value of the function h(x) = -4x - 7 at x = 3 will be -19.
What is function ?The function is defined as a relation between a set of inputs having one output each.
We have,
h(x) = -4x - 7,
So,
When
x = 3
So,
Substituting x = 3 in the given function,
i.e.
h(x) = -4x - 7
We get,
h(3) = -4 * 3 - 7
h(3) = -12 - 7
So,
h(3) = -19
So, the given function at x = 3 is -19.
Hence, we can say that the value of the function h(x) = -4x - 7 at x = 3 will be -19.

A. They are supplementary angles,
What is mean by Angle?An angle is a combination of two rays (half-lines) with a common endpoint. The latter is known as the vertex of the angle and the rays as the sides, sometimes as the legs and sometimes the arms of the angle.
Given that;
Measure of angle m ∠AXC and m ∠BXC are,
m ∠AXC = 100 deg.
m ∠BXC = 80 deg.
Hence, We get;
m ∠AXC + m ∠BXC
= 100 + 80
= 180 degree

Help me with this!!!!
Answer:
u = 21
Step-by-step explanation:
WX = XY because (VW = VY)
WX = u + 42
XY = 3u
u + 42 = 3u
42 = 3u - u
42 = 2u
u = 42 / 2
u = 21
Answer:
u = 21
Step-by-step explanation:
Consider triangle XWV and triange XYV
XV = XV (common)
Angle XVW = Angle XVY (given)
VW = VY (given)
∴triangle XWV ≅ triange XYV (SAS)
∴ XW = XY (corr. sides, ≅ triangles)
u + 42 = 3u
u = 21

The school band will sell pizzas to raise money for new uniforms. The supplier charges $97.00 plus $6.00 per pizza. The band members sell the pizza for $8.00 each. Enter and solve an inequality to find how many pizzas the band members will have to sell to make a profit. Let p be the numbers of pizzas sold. The inequality is ? The band members will need to sell at least __. pizzas.
Answer:
49 pizzas
Step-by-step explanation:
Start by writing it as a equation,
P stands for Pizza
6p +97 = 8p
Minus 6p from both sides
97=2p
Divide by 2
P= 48.5
You would need to round up, so it would be 49 pizza

Answer and Step-by-step explanation:
4. We are finding line AC.
AB is congruent to BC because the angles at the top are both 30 because of angle bisector. BD is congruent to BD, so triangles are congruent by SAS theorem. That means AB is congruent to BC by CPCTC (Congruent Parts of Congruent Triangles are Congruent).
With that being said, we can equal the expressions together.
-x + 25 = 3(2x - 8)
-x + 25 = 6x - 24
49 = 7x
7 = x
-(7) + 25 = 18
3(2(7) - 8) = 3(14 - 8) = 3(6) = 18
18 + 18 = 36
AC = 36
6. We are finding measure of angle UTW.
We have another angle bisector, so that side is equal to itself (TV ≅ TV)
We have UV and VW having the same length, so those are congruent.
Since this is a right triangle, these triangles are congruent by the HL (Hypotenuse-Leg) Theorem.
So, now we can equal the angles together.
2x + 3 = 5x - 24
27 = 3x
9 = x
2(9) + 3 = 18 + 3 = 21
5(9) - 24 = 45 - 24 = 21
21 + 21 = 42

Answer:
1) AC = 6 cm
2) AB = 16.2 cm ( note that ^{2} is = square and \sqrt{ this is = square root)
3) BC = 12.65cm
Step-by-step explanation:
1) a^{2} + b^{2} = c^{2}
4.8^{2} + 3.6^{2} = AC^{2}
36 = AC^{2}
\sqrt{ }36 = AC
AC = 6
2) a^{2} + b^{2} = c^{2}
AB^{2} + 6.75^{2} = 17.55^{2}
AB^{2} = 308.0025 - 25.5625
AB = \sqrt{ }262.44
AB = 16.2
3) a^{2} + b^{2} = c^{2}
BC^{2} + 6^{2} = 14^{2}
BC^{2} = 196 - 36
BC = \sqrt{ } 160
BC = 12.65

A cylinder has a radius of 3.2 meters its volume is 190 Cubic meters find its height to the nearest 10th of a meter
Answer:
volume = pi r^2 h
or, 190 = pi (3.2)^2 h
or, 190/10.24 = pi h
or, 18.56 = 22/7 h
or, 18.56×7/22 = h
thus , h = 5.9037
